Risk [Text Block]

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

 

Catalyst Insider Buying Fund | A D Rs Risk [Member]

Risk [Text Block]

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies.

 

Catalyst Insider Buying Fund | Commodity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Commodity Risk. Investing in the commodities markets may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal or plant disease, and geological or environmental factors, as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

 

Catalyst Insider Buying Fund | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. A counterparty to a financial instrument held by the Fund, or by a special purpose or structured vehicle invested in by the Fund, may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

 

Catalyst Insider Buying Fund | Credits Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Credit Risk. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. Credit risk may be substantial for the Fund.

 

Catalyst Insider Buying Fund | Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Currency Risk. Fluctuations in exchange rates may adversely affect the market value of the Fund’s investments. Currency risk includes the risk that the currencies in which the Fund has taken a position, or in which the Fund’s investments are denominated, will decline in value. Some currencies are illiquid, and the Fund may not be able to convert them into U.S. dollars, or may only be able to do so at an unfavorable exchange rate. Currency trading involves significant risks, including market risk, interest rate risk, country foreign investment risk, counterparty credit risk, and short sale risk.

 

Catalyst Insider Buying Fund | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

 

Catalyst Insider Buying Fund | Duration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Duration Risk. Longer-term securities may be more sensitive to interest rate changes. A heightened risk is posed by rising interest rates to a fund whose portfolios include longer-term fixed income securities. Effective duration estimates price changes for relatively small changes in rates.

 

Catalyst Insider Buying Fund | Equity Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Equity Security Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

 

Catalyst Insider Buying Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed-Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments), and extension risk (the risk that the expected rate of prepayments may decline). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

 

Catalyst Insider Buying Fund | Foreign Exchanges Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Exchange Risk. A portion of the derivatives trades made by the Fund may take place on foreign markets. Neither existing CFTC regulations nor regulations of any other U.S. governmental agency apply to transactions on foreign markets. Some of these foreign markets, in contrast to U.S. exchanges, are so-called principals’ markets in which performance is the responsibility only of the individual counterparty with whom the trader has entered into a commodity interest transaction and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty.

 

Catalyst Insider Buying Fund | Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Investment Risk. Foreign investing involves risks not typically associated with U.S. investments, including adverse fluctuations in foreign currency values, adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability, and differing auditing and legal standards. Investing in emerging markets imposes risks different from, or greater than, the risks of investing in foreign developed countries. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

 

Catalyst Insider Buying Fund | Forwards Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Forwards Risk. Forward contracts are individually negotiated and privately traded, so they are dependent upon the creditworthiness of the counterparty and subject to counterparty default risk and liquidity risk. If a counterparty defaults and fails to deliver or settle a forward trade, replacing the transaction may be costly. Liquidity risk exists because no organized secondary market exists to trade or dispose of forward obligations.

 

Catalyst Insider Buying Fund | Futures Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Futures Contract Risk. The successful use of futures contracts draws upon the Advisor’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so; and (g) leverage risk.

 

Catalyst Insider Buying Fund | Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Income Risk. The income from the Fund’s portfolio may decline because of falling market interest rates. This can result when the Fund invests the proceeds from new share sales, or from matured or called bonds, at market interest rates that are below the Fund’s current earnings rate.

 

Catalyst Insider Buying Fund | Interest Rate Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. Bond prices overall, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. For example, if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity and approximately 4.4% for a bond with 5 years to maturity. Rising interest rates pose a heightened risk to the Fund’s longer-term fixed income securities.

 

Catalyst Insider Buying Fund | Large Capitalization Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Large Capitalization Company Risk. The Fund may invest in large capitalization companies. The securities of such companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

 

Catalyst Insider Buying Fund | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of mutual funds that do not use such techniques.

 

Catalyst Insider Buying Fund | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments, and securities may become difficult to sell or illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

 

Catalyst Insider Buying Fund | Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Management Risk. The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect, and there is no guarantee that the portfolio managers’ judgment will produce the desired results.

 

Catalyst Insider Buying Fund | Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, tariffs or trade wars, international conflicts, and political events affect the securities markets.

 

Catalyst Insider Buying Fund | Medium Mid Capitalization Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Medium (Mid) Capitalization Company Risk. The earnings and prospects of mid-capitalization companies are more volatile than larger companies, they may experience higher failure rates than larger companies and normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures.

 

Catalyst Insider Buying Fund | Model And Data Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models is usually based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

 

Catalyst Insider Buying Fund | Options Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

 

Catalyst Insider Buying Fund | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the Fund’s use of options. As the buyer of a call option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not rise above the strike price, which means the option will expire worthless. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless. Conversely, as a seller (writer) of a call option or put option, the Fund will lose money if the value of the underlying reference instrument rises above (written call option) or falls below (written put option) the respective option’s strike price. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction.

 

Additionally, purchased options may decline in value due to changes in the price of the underlying reference instrument, passage of time, and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and, when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk (the risk that an option’s returns will deviate from a benchmark) and sub-strategy risk (the risk that hedging sub-strategies will not perform as expected).

 

Catalyst Insider Buying Fund | Real Estate And R E I T Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Real Estate and REIT Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and property taxes. In addition, some real estate-related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects. REITs are heavily dependent upon the management team and are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation.

 

Catalyst Insider Buying Fund | Regulatory Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Regulatory Risk. Changes in the laws or regulations of the United States or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective and could increase the operating expenses of the Fund.

 

Catalyst Insider Buying Fund | Sector Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Exposure Risk. Securities within the same sector may decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector.

 

Catalyst Insider Buying Fund | Communications Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Communications Sector Risk. Communications companies are subject to the risk that they will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition.

 

Catalyst Insider Buying Fund | Healthcare Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Healthcare Sector Risk. Companies in the healthcare sector may be heavily dependent on clinical trials with uncertain outcomes and decisions made by governments and regulatory authorities. Further, these companies are dependent on patent protection, and the expiration of patents may adversely affect the profitability of the companies. Additionally, the profitability of some healthcare companies may be dependent on a relatively limited number of products, and their products can become obsolete due to sector innovation, changes in technologies or other market developments.

 

Catalyst Insider Buying Fund | Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates, and competition for the services of qualified personnel.

 

Catalyst Insider Buying Fund | Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of an individual security or group of securities in the Fund’s portfolio.

 

Catalyst Insider Buying Fund | Small Capitalization Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Small Capitalization Company Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks, including the risk that earnings and prospects of these companies are more volatile than larger companies.

 

Catalyst Insider Buying Fund | Structured Note Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Structured Note Risk. The Fund may seek investment exposure to sectors through structured notes that may be exchange traded or may trade in the over-the-counter market. These notes are typically issued by banks or brokerage firms, and have interest and/or principal payments which are linked to changes in the price level of certain assets or to the price performance of certain indices. The value of a structured note will be influenced by time to maturity, level of supply and demand for this type of note, interest rate and market volatility, changes in the issuer’s credit quality rating, and economic, legal, political, or other events that affect the industry. In addition, there may be a lag between a change in the value of the underlying reference asset and the value of the structured note. Structured notes may also be subject to counterparty risk. The Fund may also be exposed to increased transaction costs when it seeks to sell such notes in the secondary market.

 

Catalyst Insider Buying Fund | Swaps Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swaps Risk. Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The costs of investing in swaps will be indirectly paid by the Fund.

 

Catalyst Insider Buying Fund | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. By investing in commodities indirectly through the Subsidiary, the Fund will obtain exposure to the commodities markets within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains.

 

Catalyst Insider Buying Fund | Turnover Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Turnover Rate Risk. The Fund may have portfolio turnover rates significantly in excess of 100%. Increased portfolio turnover causes the Fund to incur higher brokerage costs, which may adversely affect the Fund’s performance and may produce increased taxable distributions.

 

Catalyst Insider Buying Fund | U S Government Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Government Obligations Risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government. The Fund may be subject to such risk to the extent it invests in securities issued or guaranteed by federal agencies or authorities and U.S. government sponsored instrumentalities or enterprises.

 

Catalyst Insider Buying Fund | Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Volatility Risk. The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time, however, all investments whether long- or short-term are subject to risk of loss.

 

Catalyst Insider Buying Fund | Wholly Owned Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Wholly-Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. Shareholders of the Fund are indirectly subject to the principal risks of the Subsidiary by virtue of the Fund’s investment in the Subsidiary. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and is not subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, and the Advisor is a “commodity pool operator” registered with and regulated by the Commodity Futures Trading Commission (“CFTC”). As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations apply with respect to the Fund and the Subsidiary and subject each to CFTC penalties if reporting was found to be deficient.

Equity Security Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

Foreign Investment Risk. Foreign investing involves risks not typically associated with U.S. investments, including adverse fluctuations in foreign currency values, adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability, and differing auditing and legal standards. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

Medium (Mid) Capitalization Company Risk. The earnings and prospects of mid-capitalization companies are more volatile than larger companies, they may experience higher failure rates than larger companies and normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures.

Catalyst Energy Infrastructure Fund | Sector Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Exposure Risk. Securities within the same sector may decline in price due to sector-specific market or economic developments. The Fund typically focuses its investments in the energy sector and, therefore, is more susceptible to energy sector risk, as described above.

 

Catalyst Energy Infrastructure Fund | Security Risk [Member]

Catalyst Energy Infrastructure Fund | Distribution Policy Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Distribution Policy Risk. The Fund may, at the discretion of management, target a specific level of monthly distributions (including any return of capital) from time to time. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

 

Catalyst Energy Infrastructure Fund | Energy Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Energy Sector Risk. The Fund focuses its investments in the energy infrastructure sector, which historically has been very volatile. Because of its focus in this sector, the performance of the Fund is tied closely to, and affected by, developments in the energy sector, such as the possibility that government regulation will negatively impact companies in this sector. Energy infrastructure entities are subject to the risks specific to the industry they serve, including, but not limited to, the following:

 

● Fluctuations in commodity prices;

 

● Reduced volumes of natural gas or other energy commodities available for transporting, processing, storing or distributing;

 

● New construction risk and acquisition risk, which can limit potential growth;

 

● A sustained reduced demand for crude oil, natural gas and refined petroleum products resulting from a recession or an increase in market price or higher taxes;

 

● Depletion of the natural gas reserves or other commodities if not replaced;

 

● Changes in the regulatory environment;

 

● Extreme weather;

 

● Rising interest rates, which could result in a higher cost of capital and drive investors into other investment opportunities; and

 

● Threats of terrorist attacks.

 

Catalyst Energy Infrastructure Fund | M L P And M L P Related Securities Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

MLP and MLP-Related Securities Risks. Investments in MLPs and MLP-related securities involve risks different from those of investing in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP or MLP-related security, risks related to potential conflicts of interest between an MLP and the MLP’s general partner, cash flow risks, dilution risks (which could occur if the MLP raises capital and then invests it in projects whose return fails to exceed the cost of capital raised), and risks related to the general partner’s limited call right. MLPs and MLP-related securities are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns. Depending on the state of interest rates in general, the use of MLPs or MLP-related securities could enhance or harm the overall performance of the Fund.

 

Catalyst Energy Infrastructure Fund | M L P Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

MLP Tax Risk. Typically, MLPs do not pay U.S. federal income tax at the partnership level. Instead, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP. Thus, if any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, it could result in a reduction of the value of your investment in the Fund and lower income, as compared to an MLP that is not taxed as a corporation.

 

Catalyst Energy Infrastructure Fund | Nondiversification Risk [Member]

Risk [Text Block]

Non-diversification Risk. Because a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of companies that could be in the same or related economic sectors, the Fund’s portfolio may be more susceptible to any single economic, technological or regulatory occurrence than the portfolio of a diversified fund.

Foreign companies are generally not subject to the same regulatory requirements as U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

Large Capitalization Company Risk. The Fund may invest in large capitalization companies. The securities of such companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities, and may be unable to attain high growth rates during periods of economic expansion.

Medium (Mid) Capitalization Company Risk. The earnings and prospects of mid-capitalization companies are more volatile than larger companies, they may experience higher failure rates than larger companies and normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures.

Risk [Text Block]

Options Market Risk. Markets for options and options on futures contracts may not always operate on a fair and orderly basis. At times, prices for options and options on futures contracts may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for a Fund to effectively implement its investment strategy and achieve its objectives, and could potentially lead to significant losses.

 

Catalyst/MAP Global Equity Fund | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the Fund’s use of options. As the buyer of a call option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not rise above the strike price, which means the option will expire worthless. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless. Conversely, as a seller (writer) of a call option or put option, the Fund will lose money if the value of the underlying reference instrument rises above (written call option) or falls below (written put option) the respective option’s strike price. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction.

 

Additionally, purchased options may decline in value due to changes in the price of the underlying reference instrument, passage of time, and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and, when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk (the risk that an option’s returns will deviate from a benchmark) and sub-strategy risk (the risk that hedging sub-strategies will not perform as expected).

Sector Exposure Risk. Securities within the same sector may decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector.

 

Consumer Staples Sector Risk. The consumer staples sector may be affected by the regulation of various product components and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation.

 

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates, and competition for the services of qualified personnel.

Catalyst Tactical Allocation Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models is usually based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities.

Risk [Text Block]

Interest Rate Risk. Changes in short-term market interest rates will directly affect the yield on the shares of the Fund whose investments are normally invested in floating rate debt. If short-term market interest rates fall, the yield on the Fund’s shares will also fall. Conversely, when short-term market interest rates increase, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in the Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. Rising interest rates pose a heightened risk to the Fund’s longer-term fixed income securities.

Leverage Risk. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of mutual funds that do not use such techniques.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities that may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

These notes are typically issued by banks or brokerage firms and have interest and/or principal payments which are linked to changes in the price level of certain assets or to the price performance of certain indices. The value of a structured note will be influenced by time to maturity, level of supply and demand for this type of note, interest rate and market volatility, changes in the issuer’s credit quality rating, and economic, legal, political, or other events that affect the industry.

Swaps Risk. Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace.

Risk [Text Block]

Tax Risk. Certain of the Fund’s investment strategies, including transactions in total return swaps, may be subject to special tax rules, the effect of which may have adverse tax consequences for the Fund. By investing in commodities indirectly through the Subsidiary, the Fund intends to obtain exposure to the commodities markets within the U.S. federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains. The Subsidiary declares and distributes a dividend to the Fund, no less than annually, as the sole shareholder of the Subsidiary, in an amount approximately equal to the total amount of “Subpart F” income (as defined in Section 951 of the Internal Revenue Code of 1986, as amended) generated by or expected to be generated by the Subsidiary’s investments during the fiscal year. If the Subsidiary were to fail to make sufficient dividend distributions to the Fund, all or a portion of the income from the Fund’s investment in the Subsidiary might not be qualifying income, and the Fund might not qualify as a regulated investment company for one or more years.

Risk [Text Block]

Wholly-Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. Shareholders of the Fund are indirectly subject to the principal risks of the Subsidiary by virtue of the Fund’s investment in the Subsidiary. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the Investment Company Act of 1940, as amended, and is not subject to all the investor protections of the act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns. Your cost of investing in the Fund will be higher because you indirectly bear the expenses of the Subsidiary. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, and the Advisor is a “commodity pool operator” registered with and regulated by the Commodity Futures Trading Commission (“CFTC”). As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations apply with respect to the Fund and the Subsidiary and subject each to CFTC penalties if reporting was found to be deficient.

Risk [Text Block]

Forward Contract Risk. Forward contracts are individually negotiated and privately traded, so they are dependent upon the creditworthiness of the counterparty and subject to counterparty default risk and liquidity risk. If a counterparty defaults and fails to deliver or settle a forward trade, replacing the transaction may be costly. Liquidity risk exists because no organized secondary market exists to trade or dispose of forward obligations.

Futures Contract Risk. The successful use of futures contracts draws upon the Advisor’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so; and (g) leverage risk.

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory or other events or conditions affecting countries within the specific geographic regions in which the Fund invests. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date, or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value may be more volatile than a more geographically diversified fund.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Underlying Fund Risk. Because the Fund may invest in other investment companies, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Equity Security Risk. Equity securities, including common stocks, are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

 

Catalyst Systematic High Income Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, a increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Leverage Risk. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of mutual funds that do not use such techniques.

 

Catalyst Systematic High Income Fund | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and, if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

Catalyst Systematic High Income Fund | Model And Data Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results, and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models are usually based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

 

Catalyst Systematic High Income Fund | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. The Fund’s strategy involves the sale and purchase of call and put options. A seller (writer) of a call option will lose money if the underlying security on which the option was written increases in value to a level above the strike price of the sold option plus the premium received. Since there is no limit on how high a value of an entity can go, there is material risk in being short a call with no offsetting position. A seller (writer) of a put option will lose money if the underlying security on which the option was written decreases in value to a level below the strike price of the sold option less the premium received. The seller of a put option is limited to losing the difference between the strike price less the premium received and $0, reflecting a full loss of all value for the underlying security. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction. A seller of an option can be liquidated if the value of the underlying security advances enough in the case of a call option or declines enough in the case of a put option, given there are no offsetting positions or enough capital to offset the unrealized losses. In a liquidation event, one should expect material realized losses.

 

A buyer of a call or put option risks the loss of the entire premium invested in the option. If the underlying security is not above the strike price at maturity of a call, or not below the strike price at maturity of a put, the option will expire worthless.

 

Additionally, purchased options may decline in value due to changes in price of the underlying reference instrument, passage of time, and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and, when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk (the risk that an option’s returns will deviate from a benchmark), and sub-strategy risk (the risk that hedging sub-strategies will not perform as expected).

Real Estate and REIT Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These risks may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects. REITs are heavily dependent upon the management team and are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation.

Structured Note Risk. The Fund may seek investment exposure to sectors through structured notes that may be exchange-traded or may trade in the over-the-counter market. These notes are typically issued by banks or brokerage firms and have interest and/or principal payments which are linked to changes in the price level of certain assets or to the price performance of certain indices. The value of a structured note will be influenced by time to maturity, level of supply and demand for this type of note, interest rate and market volatility, changes in the issuer’s credit quality rating, and economic, legal, political, or other events that affect the industry.

Distribution Policy Risk. The Fund may, at the discretion of management, target a specific level of monthly distributions (including any return of capital) from time to time. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

The Fund continues to bear the risk that it will lose money if the value of the security falls below the strike price. As the buyer of a call option, the Fund assumes the risk that the market price of the underlying security will not increase above the strike price plus the premiums paid, so the Fund bears the risk that it will lose the premium paid for the option.

Like an open-end investment company (mutual fund), the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop; and (iii) market trading in the ETF may be halted under certain circumstances.

Risk [Text Block]

Managed Volatility Risk. Techniques used by the Sub-Advisor to manage the volatility of the Fund’s investments carry the risks that such techniques may not protect against market declines. The techniques may also limit the Fund’s participation in market gains, particularly during periods where market values are increasing but market volatility is high. Further, such techniques may increase portfolio transaction costs, which could result in losses or reduced gains. They also may not be successful, as the techniques are subject to the Sub-Advisor’s ability to correctly analyze and implement the volatility management techniques in a timely manner.

Risk [Text Block]

Short Position Risk. The Fund will incur a loss as a result of a short position if the price of the short position instrument increases in value between the date of the short position sale and the date on which the Fund purchases an offsetting position. Short positions may be considered speculative transactions and involve special risks, including greater reliance on the ability to accurately anticipate the future value of a security or instrument. The Fund’s losses are potentially unlimited in a short position transaction.

 

Catalyst Buffered Shield Fund | Turnover Risk [Member]

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

 

Catalyst/Millburn Hedge Strategy Fund | Commodity Risk [Member]

Counterparty Risk. A counterparty to a financial instrument held by the Fund, or by a special purpose or structured vehicle invested in by the Fund, may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Risk [Text Block]

Currency Risk. Fluctuations in exchange rates may adversely affect the market value of a Fund’s investments. Currency risk includes the risk that the currencies in which a Fund has taken a position, or in which a Fund’s investments are denominated, will decline in value. Some currencies are illiquid, and a Fund may not be able to convert them into U.S. dollars, or may only be able to do so at an unfavorable exchange rate. Currency trading involves significant risks, including market risk, interest rate risk, foreign investment risk, counterparty credit risk, and short sale risk.

 

Catalyst/Millburn Hedge Strategy Fund | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Equity Security Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

 

Catalyst/Millburn Hedge Strategy Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed-Income Risk. When the Fund invests in fixed-income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline.

 

Catalyst/Millburn Hedge Strategy Fund | Foreign Exchanges Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Exchanges Risk: A portion of the derivatives trades made by the Fund may take place on foreign markets. Neither existing CFTC regulations nor regulations of any other U.S. governmental agency apply to transactions on foreign markets. Some of these foreign markets, in contrast to U.S. exchanges, are so-called principals’ markets in which performance is the responsibility only of the individual counterparty with whom the trader has entered into a commodity interest transaction and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty.

Foreign Investment Risk. Foreign investing involves risks not typically associated with U.S. investments, including adverse fluctuations in foreign currency values, adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability, and differing auditing and legal standards. Investing in emerging markets imposes risks different from, or greater than, the risks of investing in foreign developed countries.

 

Catalyst/Millburn Hedge Strategy Fund | Forwards Risk [Member]  
Prospectus [Line Items]

Forward Contract Risk. Forward contracts are individually negotiated and privately traded, so they are dependent upon the creditworthiness of the counterparty and subject to counterparty default risk and liquidity risk. If a counterparty defaults and fails to deliver or settle a forward trade, replacing the transaction may be costly. Liquidity risk exists because no organized secondary market exists to trade or dispose of forward obligations.

 

 

Catalyst/Millburn Hedge Strategy Fund | Interest Rate Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. Rising interest rates may pose a heightened risk to the Fund’s longer-term fixed income securities.

 

Catalyst/Millburn Hedge Strategy Fund | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. Using derivatives like futures, forwards, options and swaps to increase the Fund’s combined long and short exposure creates leverage, which can magnify the Fund’s potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund’s share price.

 

Catalyst/Millburn Hedge Strategy Fund | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

Market Risk. Overall securities and derivatives market risks may affect the value of individual instruments in which the Fund invests. Factors such as domestic and foreign economic growth and market conditions, interest rate levels, tariffs or trade wars, international conflicts, and political events affect the securities and derivatives markets. When the value of the Fund’s investments goes down, your investment in the Fund decreases in value and you could lose money.

 

Catalyst/Millburn Hedge Strategy Fund | Model And Data Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Sub-Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models are usually based on data supplied by third parties, the success of the Sub-Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives, and could potentially lead to significant losses.

 

Catalyst/Millburn Hedge Strategy Fund | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the sale and purchase of call and put options. As the seller (writer) of a call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received, and gives up the opportunity for gain on the underlying security above the exercise option price. Because they are unhedged, the Fund’s written calls expose the Fund to potentially unlimited losses.

Regulatory Risk. Changes in the laws or regulations of the United States or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective, and could increase the operating expenses of the Fund.

 

Catalyst/Millburn Hedge Strategy Fund | Swaps Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Swaps Risk. Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The costs of investing in swaps will be indirectly paid by the Fund.

 

Catalyst/Millburn Hedge Strategy Fund | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. By investing in commodities indirectly through the Subsidiary, the Fund will obtain exposure to the commodities markets within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains.

Catalyst/Millburn Hedge Strategy Fund | Wholly Owned Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Wholly-Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. Shareholders of the Fund are indirectly subject to the principal risks of the Subsidiary by virtue of the Fund’s investment in the Subsidiary. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the Investment Company Act of 1940 Act, as amended (the “1940 Act”), and is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, as amended, and the Advisor is a “commodity pool operator” registered with and regulated by the Commodity Futures Trading Commission (“CFTC”). As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations apply with respect to the Fund and the Subsidiary and subject each to CFTC penalties if reporting was found to be deficient.

Catalyst/Millburn Hedge Strategy Fund | Underlying Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Underlying Fund Risk. Because the Fund may invest in other investment companies, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

Cash and Cash Equivalents Risk. At any time, the Fund may have significant investments in cash and cash equivalents.

Emerging Market Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Emerging market economies may be based on only a few industries, and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid. There may also be less reliable or publicly available information about emerging markets due to non-uniform regulatory, auditing or financial recordkeeping standards, which could cause errors in the implementation of the Fund’s investment strategy. The Fund’s performance may depend on issues other than those that affect U.S. companies and may be adversely affected by different rights and remedies associated with emerging market investments, or the lack thereof, compared to those associated with U.S. companies.

Futures Contract Risk. The successful use of futures contracts draws upon the Advisor’s or Sub-Advisor’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures a contracts are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Advisor’s or Sub-Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

Catalyst Nasdaq-100 Hedged Income Fund | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the Fund’s use of options. As the buyer of a call option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not rise above the strike price, which means the option will expire worthless. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless. Conversely, as a seller (writer) of a call option or put option, the Fund will lose money if the value of the underlying reference instrument rises above (written call option) or falls below (written put option) the respective option’s strike price. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction.

 

A buyer of a call or put option risks the loss of the entire premium invested in the option. If the price of the underlying security is not above the strike price at maturity of a call, or not below the strike price at maturity of a put, the option will expire worthless.

 

Additionally, purchased options may decline in value due to changes in price of the underlying reference instrument, passage of time, and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and, when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk (the risk that an option’s returns will deviate from a benchmark), and sub-strategy risk (the risk that hedging sub-strategies will not perform as expected).

 

Call Options Risk. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received and gives up the opportunity for gain on the underlying security above the exercise option price. The Fund continues to bear the risk that it will lose money if the value of the security falls below the strike price. Option premiums are treated as short-term capital gains and, when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. As the buyer of a call option, the Fund assumes the risk that the market price of the underlying security will not increase above the strike price plus the premiums paid, so the Fund bears the risk that it will lose the premium paid for the option.

Sector Exposure Risk. Sector exposure risk is the possibility that securities within the same sector will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a mutual fund that invests in a broader range of sectors.

 

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates, and competition for the services of qualified personnel.

Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

Exchange-Traded Fund (“ETFs”) Risk. Like an open-end investment company (mutual fund), the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop; and (iii) market trading in the ETF may be halted under certain circumstances. Shareholders of the Fund will bear the expenses of the Fund’s investment in ETFs as well as the Fund’s own operating expenses.

Risk [Text Block]

Futures Contract Risk: The successful use of futures contracts draws upon the Sub-Advisor’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) investments in futures contracts involves leverage, which means a small percentage of assets in futures or forward contracts can have a disproportionately large impact on the Fund, and the Fund can lose more than the principal amount invested; (d) losses caused by unanticipated market movements, which are potentially unlimited; (e) the Sub-Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (f) the possibility that the counterparty will default in the performance of its obligations; and (g) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

Risk [Text Block]

Currency Risk. Fluctuations in exchange rates may adversely affect the market value of a Fund’s investments. Currency risk includes the risk that the currencies in which a Fund has taken a position, or in which a Fund’s investments are denominated, will decline in value. Some currencies are illiquid, and a Fund may not be able to convert them into U.S. dollars, or may only be able to do so at an unfavorable exchange rate. Currency trading involves significant risks, including market risk, interest rate risk, foreign investment risk, counterparty credit risk, and short sale risk.

 

Catalyst/Aspect Enhanced Multi-Asset Fund | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative instruments may be less liquid than more traditional investments, and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Equity Security Risk. Equity securities, including common stocks, are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

Prospectus [Line Items]  
Risk [Text Block]

Fixed-Income Risk. When the Fund invests in fixed-income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced or fluctuate more than other types of investments.

Risk [Text Block]

Foreign Exchanges Risk. A portion of the derivatives trades made by the Fund may take place on foreign markets. Neither existing CFTC regulations nor regulations of any other U.S. governmental agency apply to transactions on foreign markets. Some of these foreign markets, in contrast to U.S. exchanges, are so-called principals’ markets in which performance is the responsibility only of the individual counterparty with whom the trader has entered into a commodity interest transaction and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty.

Foreign Investment Risk. Since the Fund’s investments may include foreign securities, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements of U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

Forward Contract Risk. Forward contracts are individually negotiated and privately traded so they are dependent upon the creditworthiness of the counterparty and subject to counterparty default risk and liquidity risk. If a counterparty defaults and fails to deliver or settle a forward trade, replacing the transaction may be costly. Liquidity risk exists because no organized secondary market exists to trade or dispose of forward obligations.

 

Catalyst/Aspect Enhanced Multi-Asset Fund | Interest Rate Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. Changes in short-term market interest rates will directly affect the yield on the shares of the Fund whose investments are normally invested in floating rate debt. If short-term market interest rates fall, the yield on the Fund’s shares will also fall. Conversely, when short-term market interest rates increase, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in the Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. Rising interet rates pose a heightened risk to the Fund because its portfolio includes longer-term fixed income securities.

Risk [Text Block]

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Sub-Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models are usually based on data supplied by third parties, the success of the Sub-Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. Certain of the Fund’s investment strategies, including transactions in futures, may be subject to special tax rules, the effect of which may have adverse tax consequences for the Fund. By investing in commodities indirectly through the Subsidiary, the Fund intends to obtain exposure to the commodities markets within the U.S. federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains. The Subsidiary declares and distributes a dividend to the Fund, no less than annually, as the sole shareholder of the Subsidiary, in an amount approximately equal to the total amount of “Subpart F” income (as defined in Section 951 of the Internal Revenue Code of 1986, as amended, generated, or expected to be generated, by the Subsidiary’s investments during the fiscal year. If the Subsidiary were to fail to make sufficient dividend distributions to the Fund, all or a portion of the income from the Fund’s investment in the Subsidiary might not be qualifying income, and the Fund might not qualify as a regulated investment company for one or more years.

Risk [Text Block]

Wholly-Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. Shareholders of the Fund are indirectly subject to the principal risks of the Subsidiary by virtue of the Fund’s investment in the Subsidiary. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, as amended, and the Advisor is a “commodity pool operator” registered with and regulated by the Commodity Futures Trading Commission (“CFTC”). As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations apply with respect to the Fund and the Subsidiary and subject each to CFTC penalties if reporting was found to be deficient.

Underlying Fund Risk. Because the Fund may invest in other investment companies, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

The cost of investing in the Fund will be higher than the cost of investing directly in the ETFs in which it invests, and may be higher than other mutual funds that invest directly in stocks and bonds. Each ETF is subject to specific risks, depending on the nature of the ETF. Like an open-end investment company (mutual fund), the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop; (iii) market trading in the ETF may be halted under certain circumstances; and (iv) the value of an ETF can fluctuate based on the prices of the securities held by the ETF.

Short Position Risk. The Fund will incur a loss as a result of a short position if the price of the short position instrument increases in value between the date of the short position sale and the date on which the Fund purchases an offsetting position. Short positions may be considered speculative transactions and involve special risks, including greater reliance on the ability to accurately anticipate the future value of a security or instrument. The Fund’s losses are potentially unlimited in a short position transaction.

Catalyst/Aspect Enhanced Multi-Asset Fund | Emerging Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Emerging Markets Risk. The Fund may invest in countries with newly organized or less developed securities markets. There are typically greater risks involved in investing in emerging markets securities. Generally, economic structures in these countries are less diverse and mature than those in developed countries, and their political systems tend to be less stable. There may also be less reliable or publicly available information about emerging markets due to non-uniform regulatory, auditing or financial recordkeeping standards (including material limits on PCAOB inspection, investigation, and enforcement), which could cause errors in the implementation of the Fund’s investment strategy. Emerging market economies may be based on only a few industries, therefore security issuers, including governments, may be more susceptible to economic weakness and more likely to default. Emerging market countries also may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. The Fund’s performance may depend on issues other than those that affect U.S. companies and may be adversely affected by different rights and remedies associated with emerging market investments, or the lack thereof, compared to those associated with U.S. companies. Investments in emerging market countries may be affected by government policies that restrict foreign investment in certain issuers or industries.

Catalyst Insider Income Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments), and extension risk (the debtor may pay its obligation later than expected). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

 

Catalyst Insider Income Fund | Interest Rate Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. For example, if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity, and approximately 4.4% for a bond with 5 years to maturity. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

Real Estate and REIT Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and property taxes. In addition, some real estate-related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects. REITs are heavily dependent upon the management team and are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. Subprime mortgages are riskier and potentially less liquid than other mortgage-backed securities.

Risk [Text Block]

Sector Exposure Risk. Securities within the same sector may decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a mutual fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

Convertible Securities Risk. Convertible securities are hybrid securities that have characteristics of both fixed income and equity securities, and are therefore subject to the risks associated with both fixed income and equity securities.

Credit Risk. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. The Fund may invest in high-yield, high-risk securities, commonly called “junk bonds,” that are not investment grade and are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. Credit risk may be substantial for the Fund.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default, illiquidity of the instrument, and changes in value based on public perception of the issuer. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

 

Catalyst/SMH High Income Fund | Fixed Income Risk [Member]

Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments), and extension risk (the debtor may pay its obligation later than expected. These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. For example, if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity, and approximately 4.4% for a bond with 5 years to maturity. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

Medium (Mid) Capitalization Company Risk. The earnings and prospects of mid-capitalization companies are generally more volatile than larger companies, they may experience higher failure rates than larger companies, and normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures.

 

Catalyst/SMH High Income Fund | Sector Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Exposure Risk. Securities within the same sector may decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a mutual fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of an individual security or group of securities in the Fund’s portfolio. There can be no guarantee the securities held by the Fund will appreciate in value.

 

Catalyst/SMH High Income Fund | Nondiversification Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-diversification Risk. Because a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of companies that could be in the same or related economic sectors, the Fund’s portfolio may be more susceptible to any single economic, technological or regulatory occurrence than the portfolio of a diversified fund.

Convertible Securities Risk. Convertible securities are hybrid securities that have characteristics of both fixed income and equity securities, and are therefore subject to the risks associated with both fixed income and equity securities. The market value of convertible securities and other debt securities tends to fall when prevailing interest rates rise. The market value of convertible securities also tends to change whenever the market value of the underlying common or preferred stock fluctuates.

The Fund may invest in high-yield, high-risk securities, commonly called “junk bonds,” that are not investment grade and are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. Credit risk may be substantial for the Fund.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default, illiquidity of the instrument, and changes in value based on public perception of the issuer. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Risk [Text Block]

Underlying Fund Risk. Because the Fund may invest in other investment companies, including mutual funds, ETFs, closed-end funds or private funds, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

Catalyst/SMH High Income Fund | Preferred Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Preferred Stock Risk. The value of preferred stocks will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of preferred stock. Preferred stocks are also subject to credit risk, which is the possibility that an issuer of preferred stock will fail to make its dividend payments. Preferred stock prices tend to move more slowly upwards than common stock prices. In an issuer bankruptcy, preferred stock holders are subordinate to the claims of debtholders and may receive little or no recovery.

 

Catalyst/SMH High Income Fund | Consumer Discretionary Sector Risk [Member]

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, trade policies, exchange rates, competition, consumer confidence, changes in demographics, and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns.

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. In addition to the risks of investing in foreign securities discussed below, there is no guarantee that an ADR issuer will continue to offer a particular ADR. As a result, the Fund may have difficulty selling the ADR, or selling them quickly and efficiently at the prices at which they have been valued. In a sponsored ADR arrangement, the foreign company assumes the obligation to pay some or all of the depositary’s transaction fees.

The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects. REITs are heavily dependent upon the management team and are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation.

Distribution Policy Risk. The Fund may, at the discretion of management, target a specific level of monthly distributions (including any return of capital) from time to time. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that a return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

Business Development Companies (“BDC”) Risk. BDCs may carry risks similar to those of a private equity or venture capital fund. BDC company securities are not redeemable at the option of the shareholder and they may trade in the market at a discount to their net asset value. A BDC is a form of investment company that is required to invest at least 70% of its total assets in securities (typically debt) of private companies, thinly traded U.S. public companies, or short-term high-quality debt securities. The BDCs held by the Fund may leverage their portfolios through borrowings or the issuance of preferred stock. While leverage often serves to increase the yield of a BDC, this leverage also subjects a BDC to increased risks, including the likelihood of increased volatility and the possibility that a BDC’s common share income will fall if the dividend rate of the preferred shares or the interest rate on any borrowings rises.

Foreign Investments Risk. Since the Fund’s investments may include ADRs and foreign securities, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

MLP and MLP-Related Securities Risk. Investments in MLPs and MLP-related securities involve risks different from those of investing in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP or MLP-related security, risks related to potential conflicts of interest between an MLP and the MLP’s general partner, cash flow risks, dilution risks (which could occur if the MLP raises capital and then invests it in projects whose return fails to exceed the cost of capital raised), and risks related to the general partner’s limited call right. MLPs and MLP-related securities are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns. Depending on the state of interest rates in general, the use of MLPs or MLP-related securities could enhance or harm the overall performance of a Fund.

Options Risk. There are risks associated with the sale and purchase of call and put options. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received, and gives up the opportunity for gain on the underlying security above the exercise option price. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option. As a seller (writer) of a put option, the Fund will lose money if the value of the underlying security falls below the strike price; the Fund’s losses are potentially large in a written put transaction. If unhedged, the Fund’s written call options expose the Fund to potentially unlimited losses. As a seller (writer) of a put option, the Fund will lose money if the value of the underlying reference instrument increases above the strike price. The Fund’s losses are potentially unlimited in a written transaction.

The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

Emerging Markets Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Emerging market economies may be based on only a few industries, and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid. There may also be less reliable or publicly available information about emerging markets due to non-uniform regulatory, auditing or financial recordkeeping standards, which could cause errors in the implementation of the Fund’s investment strategy. The Fund’s performance may depend on issues other than those that affect U.S. companies, and may be adversely affected by different rights and remedies associated with emerging market investments, or the lack thereof, compared to those associated with U.S. companies.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

Counterparty Risk. Counterparty risk is the risk that a counterparty to a financial instrument held by the Fund, or by a special purpose or structured vehicle invested in by the Fund, may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

 

Catalyst/CIFC Senior Secured Income Fund | Derivatives Risk [Member]

Risk [Text Block]

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events; changes in interest rates; and inflation and deflation. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. In addition, Rule 18f-4 under the Investment Company Act of 1940, as amended, which governs the use of derivatives and certain related instruments (including non-standard settlement cycle securities, such as bank loans), provides that a transaction with a non-standard settlement cycle will be deemed not to involve a senior security, provided that the Fund intends to physically settle the transaction and the transaction will settle within 35 days of its trade date. Compliance with Rule 18f-4 could have an adverse impact on the Fund’s performance and ability to implement its strategies. If more than a limited number of transactions with non-standard settlement cycles (including bank loans) settle later than 35 days of their trade date, such transactions could be deemed “derivatives transactions” for purposes of Rule 18f-4, requiring the Fund to adopt and implement a derivatives risk management program and apply a value-at-risk based limit to its use of derivatives transactions.

 

Catalyst/CIFC Senior Secured Income Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments), and extension risk (the debtor may pay its obligation later than expected). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

 

Catalyst/CIFC Senior Secured Income Fund | Futures Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Futures Contract Risk. The Fund’s use of futures contracts involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) leverage risk, which means that a small percentage of assets invested in futures contracts can have a disproportionately large impact; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the futures contract may not correlate perfectly with the underlying reference instrument. Investments in futures contracts involve leverage, which means a small percentage of assets invested in futures contracts can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. Futures contracts may become mispriced or improperly valued when compared to the Sub-Advisor’s expectation and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying reference instrument because of temporary, or even long-term, supply and demand imbalances and because futures contracts do not pay dividends unlike the stocks upon which certain futures contracts are based.

 

Catalyst/CIFC Senior Secured Income Fund | Interest Rate Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Fixed-rate bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. For example, if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity and approximately 4.4% for a bond with 5 years to maturity. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

 

In addition, an economic downturn or period of rising interest rates could adversely affect the market for these instruments and reduce the Fund’s ability to sell them, negatively impacting the performance of the Fund. The Fund’s floating rate loans are subject to potentially higher interest rate risk as the interest paid on the floating rate loans adjusts periodically based on changes in widely accepted reference rates, such as the Secured Overnight Financing Rate (“SOFR”). A substantial increase in interest rates could have a material adverse effect on the performance of the Fund.

Catalyst/CIFC Senior Secured Income Fund | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the sale and purchase of call and put options. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received, and gives up the opportunity for gain on the underlying security above the exercise option price. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option. As a seller (writer) of a put option, the Fund will lose money if the value of the security falls below the strike price; the Fund’s losses are potentially large in a written put transaction. If unhedged, the Fund’s written calls expose the Fund to potentially unlimited losses. As a seller (writer) of a call option, the Fund will lose money if the value of the security increases above the strike price; the Fund’s losses are potentially unlimited in a written call transaction.

Risk [Text Block]

Sector Exposure Risk. Securities within the same sector may decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a mutual fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

Junk Bond Risk. Lower-quality bonds and other debt, including lower-quality loans, known generally as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default, illiquidity of the instrument, and changes in value based on public perception of the issuer. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Underlying Fund Risk. Because the Fund may invest in other investment companies, including mutual funds, ETFs, closed-end funds or private funds, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

Foreign Investments Risk. The value of foreign investments is indirectly subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements of U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies. To the extent investments are made in the instruments of issuers from a limited number of countries, events in those countries will have a more significant impact on the Fund. Foreign investments may have less liquid trading markets, extreme price volatility, changes in economic, political, regulatory and social conditions, sustained economic downturns, financial instability, tax burdens, and investment and repatriation restrictions. Withholding and other non-U.S. taxes may decrease the Fund’s return. Non-U.S. issuers may be located in parts of the world that have historically been prone to natural disasters.

CLOs Risk. CLOs are securities backed by an underlying portfolio of loan obligations. CLOs issue classes, or “tranches,” of debt that vary in risk and yield and may experience substantial losses due to actual defaults, decrease of market value due to collateral defaults and exhaustion of subordinate tranches, market anticipation of defaults, and investor aversion to CLO securities as a class. The risks of investing in CLOs depend largely on the tranche invested in and the type of the underlying loans in the tranche of the CLO in which the Fund invests. Subordinate tranche investments involve greater risk of loss than more senior tranches. CLOs also carry risks, including, but not limited to, interest rate risk and credit risk.

 

Catalyst/CIFC Senior Secured Income Fund | Covenant Lite Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

“Covenant-lite” Obligations Risk. Covenant-lite obligations contain fewer maintenance covenants than other obligations, or no maintenance covenants, and may not include terms that allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. Covenant-lite obligations may carry more risk than traditional loans, as they allow borrowers to engage in activities that would otherwise be difficult or impossible under a covenant-heavy loan agreement. In the event of default, covenant-lite obligations may exhibit diminished recovery values, as the lender may not have the opportunity to negotiate with the borrower prior to default. As a result of its investments in covenant-lite obligations, the Fund may suffer increased losses, especially during a downturn in the credit cycle or changes in market conditions.

 

Catalyst/CIFC Senior Secured Income Fund | Credit Risk For Floating Rate Loans [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Credit Risk for Floating Rate Loans. Credit risk is the risk that the issuer of a loan or other instrument will not be able to make principal and interest payments when due, reducing the Fund’s total return. The value of the Fund’s shares, and the Fund’s ability to pay dividends, is dependent upon the performance of the assets in its portfolio. Prices of the Fund’s investments can fall if the actual or perceived financial health of the borrowers or issuers of such investments deteriorates, whether because of broad economic or issuer-specific reasons. The Fund could lose money if the issuer of a loan or debt security defaults or fails to pay interest or principal when it is due, or otherwise fails to honor its obligations. In the event of bankruptcy of a borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a senior loan. Senior loans and other floating rate instruments that are rated below investment grade are considered predominantly speculative with respect to the ability of the issuer to make timely principal and interest payments. The credit risk of a particular issuer’s debt security may vary based on its priority for repayment. For example, higher ranking (senior) debt instruments have a higher priority than lower ranking (subordinated) debt instruments. This means that the issuer might not make payments on subordinated debt instruments while continuing to make payments on senior debt instruments. In the event an issuer fails to pay scheduled interest or principal payments on an investment held by the Fund, the Fund will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid by the Fund, and likely lead to a decline in the net asset value of the Fund’s shares. Credit risk may be substantial for the Fund.

Debtor-In-Possession Loan Risks. Debtor-in-possession (DIP) loans can provide creditors with varying levels of protection, as they may carry super-priority repayment status, be secured by a lien on the borrower’s otherwise unencumbered assets, or be secured by a junior lien on the borrower’s encumbered assets. These financings are subject to the risk that the borrower will not emerge successfully from the bankruptcy/reorganization proceedings and will be forced to liquidate its assets. In the event of liquidation, the Fund’s only recourse will be against the property securing the DIP loan and any remaining unencumbered assets, which might be insufficient to repay the DIP loan in full.

Demand for Loans Risk. An increase in demand for loans may benefit the Fund by providing increased liquidity for such loans and higher sales prices, but it may also adversely affect the rate of interest payable on such loans acquired by the Fund and the rights provided to the Fund under the terms of the applicable loan agreement, and may increase the price of loans that the Fund wishes to purchase in the secondary market. A decrease in the demand for loans may adversely affect the price of loans in the Fund’s portfolio, which could cause the Fund’s net asset value to decline.

Focused Investment Risk. The Fund’s portfolio may be focused on a limited number of industries, asset classes, countries, or issuers. Investments focused on a limited number of industries, asset classes, countries, or issuers that are subject to the same or similar risk factors, and investments whose prices are closely correlated, are subject to greater overall risk than investments that are more diversified or whose prices are not as closely correlated. The focus of the Fund’s portfolio in any issuers would subject the Fund to a greater degree of risk with respect to market price volatility or defaults by such issuers, and the focus of the portfolio in any one industry, asset class or country would subject the Fund to a greater degree of risk with respect to economic downturns relating to such industry, asset class, or country.

Limited Secondary Market for Floating Rate Loans Risk. There is no organized exchange or board of trade on which floating rate loans are traded. Instead, the secondary market for floating rate loans is a private, unregulated inter-dealer or inter-bank resale market. Floating rate loans usually trade in large denominations. Trades can be infrequent and the market for floating rate loans may experience substantial volatility.

Liquidity for Floating Rate Loans Risk. Some instruments held by the Fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid instruments may also be difficult to value. If the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the Fund may be forced to sell at a loss or be unable to sell an investment, thereby having the effect of decreasing the Fund’s overall level of liquidity.

 

Catalyst/CIFC Senior Secured Income Fund | Loan Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Loan Risk. Investments in bank loans, also known as loans or corporate loans, of which senior loans are a type, may subject the Fund to heightened credit risks because such loans tend to be highly leveraged and potentially more susceptible to the risks of interest deferral, default and/or bankruptcy. Senior floating rate loans are often rated below investment grade, but may also be unrated. The risks associated with these loans can be similar to the risks of below investment grade fixed income instruments. An economic downturn would generally lead to a higher non-payment rate, and a senior floating rate loan may lose significant market value before a default occurs. Moreover, any specific collateral used to secure a senior floating rate loan may decline in value or become illiquid, which would adversely affect the loan’s value. Unlike the securities markets, there is no central clearinghouse for loan trades, and the loan market has not established enforceable settlement standards or remedies for failure to settle. Therefore, portfolio transactions in loans may have uncertain settlement time periods, potentially leading to the sale proceeds of such loans not being available to meet redemptions for a substantial period of time after the sale of the bank loans. Certain bank loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the protections of federal securities laws, including anti-fraud provisions.

Prospectus [Line Items]  
Risk [Text Block]

Prepayment and Extension Risks for Floating Rate Loans. Prepayment risk is the risk that principal on a debt obligation may be repaid earlier than anticipated. Floating rate loans typically have no or limited call protection and may be prepaid partially or in full at certain times and, in certain circumstances, without penalty. If a floating rate loan is prepaid, the Fund may realize proceeds that are less than the value that had been assigned to the loan and/or may be forced to reinvest the proceeds in assets with lower yields than the loan that was repaid. Prepayment risk on fixed rate investments is the risk that principal on loans or other obligations underlying a security may be repaid prior to the stated maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity. Extension risk is the risk that an issuer will exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected, which may decrease the value of the obligation and prevent the Fund from investing expected repayment proceeds in instruments paying higher yields.

Senior Loan Risk. Senior bank loans are subject to the risk that a court could subordinate a senior loan, which typically holds the most senior position in the issuer’s capital structure, to presently existing or future indebtedness, or take other action detrimental to the holders of senior loans. Lack of an active trading market, restrictions on resale, irregular trading activity, wide bid/ask spreads, and extended trade settlement periods may impair the Fund’s ability to sell senior loans within its desired time frame or at an acceptable price. Senior loans are generally less liquid than many other debt instruments, and there may be less public information available about senior loans as compared to other debt instruments. Senior loans settle on a delayed basis, potentially leading to the sale proceeds of such loans not being available to meet redemptions for a substantial period of time after the sale of the senior loans. Certain senior loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the protections of federal securities laws, including anti-fraud provisions.

Short Selling Risk. The Fund’s use of short positions to eliminate or reduce risk exposure in the Fund’s long positions may not be successful and the Fund may lose money on its long positions. An increase in the value of a security over the price at which it was sold short will result in a loss to the Fund, and there can be no assurance that the Sub-Advisor will be able to close out the position at any particular time or at an acceptable price. The loss from a short position is potentially unlimited. The Fund’s use of short sales will likely result in the creation of leverage in the Fund.

Risk [Text Block]

Valuation of Loans Risk. The Fund values its assets daily. However, because the secondary market for floating rate loans is limited, it may be difficult to value loans. Reliable market value quotations may not be readily available for some loans, and valuation of such loans may require more research than for liquid securities. In addition, elements of judgment may play a greater role in valuation of loans than for securities with a more developed secondary market because there is less reliable, objective market value data available. In addition, if the Fund purchases a relatively large portion of a loan, the limitations of the secondary market may inhibit the Fund from selling a portion of the loan and reducing its exposure to a borrower when the Sub-Advisor deems it advisable to do so.

Duration Risk. A portfolio with a longer average portfolio duration may be more sensitive to interest rate changes. Rising interest rates pose a risk to the Fund’s longer-term fixed income securities. Effective duration estimates price changes for relatively small changes in rates. If rates increase significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the increase in a security’s price.

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments), and extension risk (the debtor may pay its obligation later than expected). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. For example, if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity, and approximately 4.4% for a bond with 5 years to maturity. The maturity and effective duration of the Fund’s investment portfolio may vary materially from its target, from time to time, and there is no assurance that the maturity or effective duration of the Fund’s investment portfolio will not exceed its target. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector. Some investments held by the Fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid investments may also be difficult to value. If the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the Fund may be forced to sell at a loss.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default, illiquidity of the instrument, and changes in value based on public perception of the issuer. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

 

Catalyst Enhanced Income Strategy Fund | Underlying Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Underlying Fund Risk. Because the Fund may invest in other investment companies, including mutual funds, ETFs, closed-end funds or private funds, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

Catalyst Enhanced Income Strategy Fund | Asset Backed And Mortgage Backed Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Asset-Backed and Mortgage-Backed Securities Risk. When the Fund invests in asset-backed securities, mortgage-backed securities or CMOs, the Fund is subject to the risk that, if the issuer fails to pay interest or repay principal, the assets backing these securities may not be sufficient to support payments on the securities.

 

Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which are guaranteed by the U.S. government, its agencies or instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments and not the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by a Fund and not the purchase of shares of the Fund. Mortgage-backed securities do not have a fixed maturity, and their expected maturities may vary when interest rates rise or fall.

 

Mortgage-backed securities issued or guaranteed by private issuers are also known as “non-agency MBS.” Non-agency MBS generally are a greater credit risk than MBS issued by the U.S. government, and the market for non-agency MBS is smaller and may be less liquid than the market for government MBS.

Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and property taxes. In addition, some real estate-related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

 

Catalyst Enhanced Income Strategy Fund | Sub Prime Mortgage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sub-Prime Mortgage Risk. Lower-quality notes, such as those considered “sub-prime,” are more likely to default than those considered “prime” by a rating evaluation agency or service provider. An economic downturn or period of rising interest rates could adversely affect the market for sub-prime notes and reduce the Fund’s ability to sell these securities. The lack of a liquid market for these securities could decrease the Fund’s share price. Additionally, borrowers may seek bankruptcy protection which would delay resolution of security holder claims and may eliminate or materially reduce liquidity. Subprime mortgages are riskier, and potentially less liquid, than mortgage-backed securities.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund and those losses could be significant.

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in U.S. dollars, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.

Warrants and rights may expire worthless if the price of a common stock is below the conversion price of the warrant or right. Convertible bonds may decline in value if the price of a common stock falls below the conversion price.

Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid-sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.

Options Risk. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received and gives up the opportunity for gain on the underlying security above the exercise option price. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option. As the seller (writer) of a put option, the Fund will lose money if the value of the security falls below the strike price. The use of derivative instruments, such as options, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments, including the risk that the counterparty to an options transaction may not fulfill its contractual obligations.

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.

This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Fund’s ethical screening guidelines.

 

To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Adviser’s values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Adviser’s corporate engagements and related-activities will achieve their intended results. There is a risk that the Adviser’s activities in this regard could limit the Fund’s investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Fund’s investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Adviser’s activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.

Foreign Securities Risk. Since the Fund’s investments may include ADRs and foreign securities, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies thereby resulting in less publicly available information about these companies. In addition, foreign investing involves other risks not typically associated with U.S. investments, including adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability and differing accounting, auditing, financial reporting and legal standards.

Growth Stock Risk. “Growth” stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. “Growth” stocks also tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, “growth” stocks tend to be sensitive to changes in their earnings and more volatile in price than the stock market as a whole. In addition, companies that the Adviser believes have significant growth potential are often companies with new, limited or cyclical product lines, markets or financial resources and the management of such companies may be dependent upon one or a few key people. The stocks of such companies can therefore be subject to more abrupt or erratic market movements than stocks of larger, more established companies or the stock market in general.

Stock Value Risk. Stocks involve the risk that they may never reach what the Adviser believes is their full market value, either because the market fails to recognize the stock’s intrinsic worth, or the Adviser misgauged that worth. Stocks also may decline in price, even though, in theory, they are already undervalued. Investments in private companies that lack readily observable or market-corroborated prices generally increase stock valuation risk because they are more difficult to value. Many private companies are not required to file periodic financial reports, leading to challenges in the Adviser’s ability to evaluate a company’s business prospects and the fair value of its securities. The fair valued prices assigned to the Fund’s investments in private companies are based on a variety of factors, reviewed regularly, and updated as additional information becomes available. However, fair value pricing includes subjective judgments, and it is possible that the fair value assigned to a security may differ materially from the value the Fund would realize if the security were sold.

Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Risk [Text Block]

Interest Rate Risk. Changes in short-term market interest rates will directly affect the yield on the shares of a fund whose investments are normally invested in floating rate debt. If short-term market interest rates fall, the yield on the Fund’s shares will also fall. Conversely, when short-term market interest rates increase, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in the Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

Risk [Text Block]

Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid-sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.

Options Market Risk. Markets for options and options on futures may not always operate on a fair and orderly basis. At times, prices for options and options on futures may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

Options Risk. There are risks associated with the sale and purchase of call and put options. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received and gives up the opportunity for gain on the underlying security above the exercise option price because the Fund will no longer hold the underlying security. The use of derivative instruments, such as options, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments, including the risk that the counterparty to an options transaction may not fulfill its contractual obligations.

Risk [Text Block]

Distribution Policy Risk. The Fund’s distribution policy is not designed to generate, and is not expected to result in, distributions that equal a fixed percentage of the Fund’s current net asset value per share. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the Fund’s distribution rate or the source of a distribution from the Fund is net profit. Shareholders should note that a return of capital will reduce the tax basis of their Shares and potentially increase the taxable gain, if any, upon disposition of their Shares.

Credit Risk. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. The Fund may invest in high-yield, unrated, or otherwise high-risk securities, commonly called “junk bonds,” that are not investment grade and are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities.

Junk Bond Risk. Lower-quality or unrated bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Preferred Stock Risk. Dividends on preferred stocks are generally payable at the discretion of the issuer’s board of directors and Fund shareholders may lose money if dividends are not paid. Preferred stock prices may fall if interest rates increase or the issuer’s creditworthiness becomes impaired.

 

Eventide Balanced Fund | Asset Backed And Mortgage Backed Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Asset-Backed and Mortgage-Backed Security Risk. When the Fund invests in asset-backed securities, mortgage-backed securities or collateralized mortgage obligations, the Fund is subject to the risk that, if the issuer fails to pay interest or repay principal, the assets backing these securities may not be sufficient to support payments on the securities.

 

Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which are guaranteed by the U.S. government, its agencies or instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments and not the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by a Fund and not the purchase of Shares of the Fund. Mortgage-backed securities do not have a fixed maturity and their expected maturities may vary when interest rates rise or fall.

 

Mortgage-backed securities issued or guaranteed by private issuers are also known as “non-agency MBS.” Non-agency MBS generally are a greater credit risk than MBS issued by the U.S. government, and the market for non-agency MBS is smaller and may be less liquid that the market for government MBS.

Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

 

Eventide Balanced Fund | Ethical Investment Risk [Member]

Ethical Investment Risk. The Fund’s ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Fund’s ethical screening guidelines.

 

To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Adviser’s values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Adviser’s corporate engagements and related-activities will achieve their intended results. There is a risk that the Adviser’s activities in this regard could limit the Fund’s investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Fund’s investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Adviser’s activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.

 

Eventide Balanced Fund | Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities Risk. Since the Fund’s investments may include ADRs and foreign securities, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies thereby resulting in less publicly available information about these companies. In addition, foreign investing involves other risks not typically associated with U.S. investments, including adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability and differing accounting, auditing, financial reporting and legal standards.

 

Eventide Balanced Fund | Stock Value Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Stock Value Risk. Stocks involve the risk that they may never reach what the Adviser believes is their full market value, either because the market fails to recognize the stock’s intrinsic worth, or the Adviser misgauged that worth. Stocks also may decline in price, even though, in theory, they are already undervalued. Investments in private companies that lack readily observable or market-corroborated prices generally increase stock valuation risk because they are more difficult to value. Many private companies are not required to file periodic financial reports, leading to challenges in the Adviser’s ability to evaluate a company’s business prospects and the fair value of its securities. The fair valued prices assigned to the Fund’s investments in private companies are based on a variety of factors, reviewed regularly, and updated as additional information becomes available. However, fair value pricing includes subjective judgments, and it is possible that the fair value assigned to a security may differ materially from the value the Fund would realize if the security were sold.

Extension Risk. If interest rates increase, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates increase, which could cause their values to fall sharply.

The liquidity of REITs may change dramatically over time.

Risk [Text Block]

Yieldcos Risk. Investments in securities of yieldcos involve risks that differ from investments in traditional operating companies, including risks related to the relationship between the yieldco and the company responsible for the formation of the yieldco (the “Yieldco Sponsor”). Yieldcos typically remain dependent on the management and administration services provided by or under the direction of the Yieldco Sponsor and on the ability of the Yieldco Sponsor to identify and present the yieldco with acquisition opportunities, which may often be assets of the Yieldco Sponsor itself. To the extent that the yieldco relies on the Yieldco Sponsor for developing new assets for potential future acquisitions, the yieldco may be dependent on the development capabilities and financial health of the Yieldco Sponsor. Yieldco Sponsors may have interests that conflict with the interests of the yieldco and may retain control of the yieldco via classes of stock held by the Yieldco Sponsor. Any event that limits the yieldco’s ability to maintain or grow its distributable cash flow would likely have a negative impact on the yieldco’s share price.

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in U.S. dollars, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. Dollar declines, the ADR price would decline by a similar measure.

Warrants and rights may expire worthless if the price of a common stock is below the conversion price of the warrant or right. Convertible bonds may decline in value if the price of a common stock falls below the conversion price.

If rates drop significantly, effective duration may tend to overstate the rise in a security’s price.

 

Eventide Limited-Term Bond Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the stocks of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than larger companies. These companies may experience higher failure rates than larger companies. Mid-sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.

Risk [Text Block]

Credit Risk. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. The Fund may invest in high-yield, unrated or otherwise high-risk securities, commonly called “junk bonds,” that are not investment grade and are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities.

 

Eventide Limited-Term Bond Fund | Junk Bond Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Junk Bond Risk. Lower-quality or unrated bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Preferred Stock Risk. Dividends on preferred stocks are generally payable at the discretion of the issuer’s board of directors and Fund shareholders may lose money if dividends are not paid. Preferred stock prices may fall if interest rates increase or the issuer’s creditworthiness becomes impaired.

 

Eventide Limited-Term Bond Fund | Asset Backed And Mortgage Backed Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Asset-Backed and Mortgage-Backed Security Risk. When the Fund invests in asset-backed securities, mortgage-backed securities or collateralized mortgage obligations, the Fund is subject to the risk that, if the issuer fails to pay interest or repay principal, the assets backing these securities may not be sufficient to support payments on the securities.

 

Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which are guaranteed by the U.S. government, its agencies or instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments and not the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by a Fund and not the purchase of Shares of the Fund. Mortgage-backed securities do not have a fixed maturity and their expected maturities may vary when interest rates rise or fall.

 

Commercial mortgage-backed securities (“CMBS”) are subject to credit risk because underlying loan borrowers may default. Subordinate tranches of CMBS are more sensitive to defaults. Previously non-defaulting borrowers may not be able to refinance their loans when due, resulting in higher default rates. CMBS, in general, may become illiquid. Recently, hospitality, retail, and office properties have become subject to heightened vacancy rates and an accompanying increase in the risk of default.

 

Mortgage-backed securities issued or guaranteed by private issuers are also known as “non-agency MBS.” Non-agency MBS generally are a greater credit risk than MBS issued by the U.S. government, and the market for non-agency MBS is smaller and may be less liquid that the market for government MBS.

Ethical Investment Risk. The Fund’s ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Fund’s ethical screening guidelines.

 

To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Adviser’s values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Adviser’s corporate engagements and related-activities will achieve their intended results. There is a risk that the Adviser’s activities in this regard could limit the Fund’s investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Fund’s investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Adviser’s activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.

 

Eventide Limited-Term Bond Fund | Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities Risk. Since the Fund’s investments may include ADRs and foreign securities, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies thereby resulting in less publicly available information about these companies. In addition, foreign investing involves other risks not typically associated with U.S. investments, including adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability and differing accounting, auditing, financial reporting and legal standards.

Extension Risk. If interest rates increase, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates increase, which could cause their values to fall sharply.

Risk [Text Block]

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in the U.S. dollar, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.

Equity Security Risk. Common and preferred stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Warrants and rights may expire worthless if the price of a common stock is below the conversion price of the warrant or right. Convertible bonds may decline in value if the price of a common stock falls below the conversion price. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction and global or regional political, economic and banking crises.

At times, prices for options and options on futures may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances.

Prospectus [Line Items]  
Risk [Text Block]

Options Risk. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received and gives up the opportunity for gain on the underlying security above the exercise option price because the Fund will no longer hold the underlying security. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option. As the seller (writer) of a put option, the Fund will lose money if the value of the security falls below the strike price. The use of derivative instruments, such as options, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments, including the risk that the counterparty to an options transaction may not fulfill its contractual obligations.

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. These companies may have limited product lines, markets, financial resources or personnel. The products of these companies may face obsolescence or adoption challenges due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector can be heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment. Many technologies companies are small or mid-sized companies and may be newly organized.

Eventide Exponential Technologies Fund | Growth Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Growth Stock Risk. Not all companies in the Fund’s portfolio will experience growth. “Growth” stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. “Growth” stocks also tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, “growth” stocks tend to be sensitive to changes in their earnings and more volatile in price than the stock market as a whole. In addition, companies that the Adviser believes have significant growth potential are often companies with new, limited or cyclical product lines, markets or financial resources and the management of such companies may be dependent upon one or a few key people. The stocks of such companies can therefore be subject to more abrupt or erratic market movements than stocks of larger, more established companies or the stock market in general.

 

Eventide Exponential Technologies Fund | Stock Value Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Stock Value Risk. Stocks involve the risk that they may never reach what the Adviser believes is their full market value, either because the market fails to recognize the stock’s intrinsic worth, or the Adviser misgauged that worth. Stocks also may decline in price, even though, in theory, they are already undervalued. Investments in private companies that lack readily observable or market-corroborated prices generally increase stock valuation risk because they are more difficult to value. Many private companies are not required to file periodic financial reports, leading to challenges in the Adviser’s ability to evaluate a company’s business prospects and the fair value of its securities. The fair valued prices assigned to the Fund’s investments in private companies are based on a variety of factors, reviewed regularly, and updated as additional information becomes available. However, fair value pricing includes subjective judgments, and it is possible that the fair value assigned to a security may differ materially from the value the Fund would realize if the security were sold.

Financial Technology Companies Risk. Fintech companies could result in new business models, applications, processes or products with an associated effect on the provision of financial services. Certain fintech companies may seek to disrupt or displace established financial institutions and may face competition from larger and more established companies. Fintech companies that utilize disruptive technologies may not be able to capitalize on them when facing political and/or legal attacks from competitors, industry groups or local and national governments. Newer or smaller fintech companies may not currently be profitable, and there can be no assurance that these companies will be profitable in the future. Additionally, fintech companies may be adversely impacted by potential rapid product obsolescence, cybersecurity attacks and disruptions in the technology they depend on. Legal and regulatory changes, particularly related to information privacy and data protection, may impact the products or services of fintech companies. Similarly, the collection and storage of data from consumers and other sources may face increased scrutiny as regulators consider how data may be collected, stored, safeguarded and used.

If rates drop significantly, effective duration may tend to overstate the increase in a security’s price.

 

Eventide Core Bond Fund | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Interest Rate Risk. Changes in short-term market interest rates will directly affect the yield on the shares of a fund whose investments are normally invested in floating rate debt. If short-term market interest rates fall, the yield on the Fund’s shares will also fall. Conversely, when short-term market interest rates increase, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in the Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

Preferred stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change.

 

Eventide Core Bond Fund | Asset Backed And Mortgage Backed Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Asset-Backed and Mortgage-Backed Security Risk. When the Fund invests in asset-backed securities, mortgage-backed securities or collateralized mortgage obligations, the Fund is subject to the risk that, if the issuer fails to pay interest or repay principal, the assets backing these securities may not be sufficient to support payments on the securities.

 

Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which are guaranteed by the U.S. government, its agencies or instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments and not the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by a Fund and not the purchase of Shares of the Fund. Mortgage-backed securities do not have a fixed maturity and their expected maturities may vary when interest rates rise or fall.

 

Commercial mortgage-backed securities (“CMBS”) are subject to credit risk because underlying loan borrowers may default. Subordinate tranches of CMBS are more sensitive to defaults. Previously non-defaulting borrowers may not be able to refinance their loans when due, resulting in higher default rates. CMBS, in general, may become illiquid. Recently, hospitality, retail, and office properties have become subject to heightened vacancy rates and an accompanying increase in the risk of default.

 

Mortgage-backed securities issued or guaranteed by private issuers are also known as “non-agency MBS.” Non-agency MBS generally are a greater credit risk than MBS issued by the U.S. government, and the market for non-agency MBS is smaller and may be less liquid that the market for government MBS.

Ethical Investment Risk. The Fund’s ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Fund’s ethical screening guidelines.

 

To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Adviser’s values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Adviser’s corporate engagements and related-activities will achieve their intended results. There is a risk that the Adviser’s activities in this regard could limit the Fund’s investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Fund’s investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Adviser’s activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.

 

Eventide Core Bond Fund | Foreign Securities Risk [Member]

Risk [Text Block]

Foreign Securities Risk. Since the Fund’s investments may include foreign securities, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies thereby resulting in less publicly available information about these companies. In addition, foreign investing involves other risks not typically associated with U.S. investments, including adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability and differing accounting, auditing, financial reporting and legal standards.

 

Eventide Core Bond Fund | Extension Risk [Member]

Extension Risk. If interest rates increase, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates increase, which could cause their values to fall sharply.

Prepayment Risk. The Fund may invest in debt securities that may be paid off early when the issuer of a debt security can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.

Municipal Bond Risk. The value of municipal bonds may fluctuate as a result of changes in the cash flows generated by the revenue source(s), changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source(s), or changes in federal tax laws or the activity of an issuer which may adversely affect the tax-exempt status of municipal bonds.

Sovereign Debt Risk. Investment in sovereign debt obligations involves special risks not present in corporate debt obligations. The issuer of the sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund and those losses could be significant.

 

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return and the value of the Fund and your investment.

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies. Although an ADR is priced in the U.S. dollar, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. Dollar declines, the ADR price would decline by a similar measure.

Equity Security Risk. Common and preferred stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Warrants and rights may expire worthless if the price of a common stock is below the conversion price of the warrant or right. Convertible bonds may decline in value if the price of a common stock falls below the conversion price. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction and global or regional political, economic and banking crises.

Liquidity Risk. Some securities held by the Fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid investments may also lack a readily observable or market-corroborated price and be difficult to value. If the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the Fund may be forced to sell at an unexpected loss.

Options Market Risk. Markets for options and options on futures may not always operate on a fair and orderly basis. At times, prices for options and options on futures may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

Options Risk. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received and gives up the opportunity for gain on the underlying security above the exercise option price. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option. As the seller (writer) of a put option, the Fund will lose money if the value of the security falls below the strike price. The use of derivative instruments, such as options, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments, including the risk that the counterparty to an options transaction may not fulfill its contractual obligations.

Risk [Text Block]

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.

Eventide Large Cap Focus Fund | M L P Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

MLP Tax Risk. MLPs, typically, do not pay U.S. federal income tax at the partnership level. Instead, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP. Thus, if any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, it could result in a reduction of the value of your investment in the Fund and lower income, as compared to an MLP that is not taxed as a corporation.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, trade policies, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

These may include decreases in real estate values, overbuilding, rising operating costs, interest rates and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

Risk [Text Block]

Growth Stock Risk. “Growth” stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. “Growth” stocks also tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, “growth” stocks tend to be sensitive to changes in their earnings and more volatile in price than the stock market as a whole. In addition, companies that the Adviser believes have significant growth potential are often companies with new, limited or cyclical product lines, markets or financial resources and the management of such companies may be dependent upon one or a few key people. The stocks of such companies can therefore be subject to more abrupt or erratic market movements than stocks of larger, more established companies or the stock market in general.

Healthcare & Life Sciences Sector Risk. Companies in the healthcare and life sciences sectors may be heavily dependent on clinical trials with uncertain outcomes and decisions made by the governments and regulatory authorities. Further, these companies are dependent on patent protection, and the expiration of patents may adversely affect the profitability of the companies. Additionally, the profitability of some healthcare and life sciences companies may be dependent on a relatively limited number of products, and their products can become obsolete due to sector innovation, changes in technologies or other market developments.

Eventide Large Cap Focus Fund | Stock Value Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Stock Value Risk. Stocks involve the risk that they may never reach what the Adviser believes is their full market value, either because the market fails to recognize the stock’s intrinsic worth, or the Adviser misgauged that worth. Stocks also may decline in price, even though, in theory, they are already undervalued. Investments in private companies that lack readily observable or market-corroborated prices generally increase stock valuation risk because they are more difficult to value. Many private companies are not required to file periodic financial reports, leading to challenges in the Adviser’s ability to evaluate a company’s business prospects and the fair value of its securities. The fair valued prices assigned to the Fund’s investments in private companies are based on a variety of factors, reviewed regularly, and updated as additional information becomes available. However, fair value pricing includes subjective judgments, and it is possible that the fair value assigned to a security may differ materially from the value the Fund would realize if the security were sold.

REIT Risk. The Fund’s investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets.

The liquidity of REITs may change dramatically over time.

Yieldcos Risk. Investments in securities of yieldcos involve risks that differ from investments in traditional operating companies, including risks related to the relationship between the yieldco and the company responsible for the formation of the yieldco (the “Yieldco Sponsor”). Yieldcos typically remain dependent on the management and administration services provided by or under the direction of the Yieldco Sponsor and on the ability of the Yieldco Sponsor to identify and present the yieldco with acquisition opportunities, which may often be assets of the Yieldco Sponsor itself. To the extent that the yieldco relies on the Yieldco Sponsor for developing new assets for potential future acquisitions, the yieldco may be dependent on the development capabilities and financial health of the Yieldco Sponsor. Yieldco Sponsors may have interests that conflict with the interests of the yieldco and may retain control of the yieldco via classes of stock held by the Yieldco Sponsor. Any event that limits the yieldco’s ability to maintain or grow its distributable cash flow would likely have a negative impact on the yieldco’s share price.

MLP and MLP-Related Securities. Investments in MLPs and MLP-related securities involve risks different from those of investing in common stock including risks related to limited control and limited rights to vote on matters affecting the MLP or MLP-related security, risks related to potential conflicts of interest between an MLP and the MLP’s general partner, cash flow risks, dilution risks (which could occur if the MLP raises capital and then invests it in projects whose return fails to exceed the cost of capital raised) and risks related to the general partner’s limited call right. MLPs and MLP-related securities are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns. During periods of rising interest rates, the use of MLPs or MLP-related securities could hinder the overall performance of the Fund.
