Apr. 30, 2026
Asset Allocation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Asset Allocation Risk. The sub-advisor’s asset allocation decisions among various equity investment strategies may not anticipate market trends successfully. The sub-advisor may make investment allocations among various market segments that do not perform as expected. The sub-advisor attempts to identify investment allocations that will provide consistent, quality performance for the Fund, but there is no guarantee that the allocation techniques will produce the desired results. You could lose money on your investment in the Fund as a result of these allocation decisions.
Company Size Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •  
Company Size Risk. The smaller companies in which the Fund may invest may have unproven track records, a
    limited product or service base, limited access to capital, and other attributes that can cause their share prices to fluctuate, and they may be more likely to fail than larger companies. Therefore, smaller companies may entail greater risks for investors than larger companies.
Country or Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Country or Sector Risk. Investments in particular sectors or countries may be more volatile than the overall equity or fixed-income markets. Therefore, if the Fund emphasizes one or more industries, economic sectors or countries, it may be more susceptible to financial, market, political or economic events affecting the particular issuers, industries and countries participating in such sectors than funds that do not emphasize particular industries, sectors or countries.
Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Currency Risk. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.
Depositary Receipts Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Depositary Receipts Risk. Foreign securities may trade in the form of depositary receipts. Depositary receipts represent an ownership in an underlying security that is held by the depositary. In addition to investment risks associated with the underlying issuer, depositary receipts may expose the Fund to additional risks associated with non-uniform terms that apply to depositary receipt programs, including credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency, political, economic, market risks and the risks of an illiquid market for depositary receipts. Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. Depositary receipts may not track the price of the underlying foreign securities on which they are based, may have limited voting rights, and may have a distribution subject to a fee charged by the depository. As a result, equity shares of the underlying issuer may trade at a discount or premium to the market price of the depositary receipts.
Emerging Market Countries Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Emerging Market Countries Risk. Emerging market securities typically present even greater exposure to the risks described under “Foreign Investing Risk” and may be particularly sensitive to certain economic changes. Emerging market securities are exposed to a number of risks that may make these investments volatile in price or difficult to trade. Companies in emerging market countries generally may be subject to less stringent financial reporting, accounting and auditing standards than companies in more developed countries. In addition, securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions may be limited.
Exchange Traded Funds ETFs Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •  
Exchange-Traded Funds (“ETFs”) Risk. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies, and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs may be subject to
    the following risks that do not apply to conventional funds: (i) the market price of an ETF’s shares may trade above or below their net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are delisted from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.
Foreign Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Foreign Investing Risk. Economic, political or regulatory conditions may be less favorable, and markets may be less liquid, less transparent and more volatile, in foreign countries, and in particular emerging markets, than in the United States. Currency fluctuations may reduce investment gains or add to investment losses.
Forward Currency Exchange Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Forward Currency Exchange Contract Risk. A forward foreign currency exchange contract is an agreement to buy or sell a specific currency at a future date and at a price set at the time of the contract. When used for hedging purposes, forward foreign currency exchange contracts may reduce the risk of loss from a change in value of a currency, but they also limit any potential gains, do not protect against fluctuations in the value of the underlying position and are subject to counterparty risk.
Growth Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Growth Investing Risk. Due to their relatively high valuations, growth stocks are typically more volatile than value stocks.
Information Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Information Risk. When the quantitative analytical tools (“Tools”) and information and data (“Data”) used in managing the Fund prove to be incorrect or incomplete, any investment decisions made in reliance on the Tools and Data may not produce the desired results and the Fund may realize losses.
Market Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Market Risk. There is a risk that the value of the Fund’s investments may decrease in response to expected, real or perceived economic, political or financial events in the U.S. or global markets. The frequency and magnitude of such changes in value cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market conditions, inflation, changes in interest rates, trade disputes, changes in trade regulation or economic sanctions, elevated levels of government debt, internal unrest and discord, lack of liquidity in the bond or equity markets, volatility in the equity markets, market disruptions caused by local or regional events such as war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions, the threat or occurrence of a government shutdown, or other events or adverse investor sentiment or other political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide due to increasingly interconnected global economies and financial markets. Market risk includes the risk that a particular style of investing, such as growth or value, may underperform the market generally.
Preferred Stocks Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Preferred Stocks Risk. Unlike interest payments on debt securities, dividend payments on a preferred stock typically must be declared by the issuer’s board of directors. In addition, in the event an issuer of preferred stock experiences economic difficulties, the issuer’s preferred stock may lose substantial value due to the reduced likelihood that the issuer’s board of directors will declare a dividend and the fact that the preferred stock may be subordinated to other securities of the same issuer.
Stock Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Stock Market Risk. The value of equity securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s share price may decline suddenly or over a sustained period of time.
Value Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Value Investing Risk. Due to their relatively low valuations, value stocks are typically less volatile than growth stocks and therefore may lag behind growth stocks in an up market.
Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Correlation Risk. The effectiveness of the Fund’s futures hedging program may be reduced if the Fund’s equity positions do not sufficiently correlate to the indices underlying its futures positions.
Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Counterparty Risk. When the Fund invests in financial instruments that involve counterparties, the Fund is exposed to risks associated with the credit quality of the counterparty or the ability of the counterparty to pay the Fund. Such instruments can provide exposure to a particular group of securities, index or asset class without the Fund actually purchasing those securities or investments. The Fund’s use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease.
Derivative Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Derivative Securities Risk. The risk that the Fund’s use of derivatives will cause losses (1) due to the unexpected effect of market movements on a derivative’s price; (2) because the derivatives do not perform as anticipated; (3) because the derivatives are not correlated with the performance of other investments which they are used to hedge; (4) if the Fund is unable to liquidate a position because of an illiquid secondary market or (5) because the other party to the derivative fails to make required payments (counterparty risk).
Derivatives Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Derivatives Tax Risk. Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Fund’s taxable income or gains, and may limit or prevent the Fund from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Fund to change its investment strategy. To the extent that the Fund uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Fund may not realize the intended benefits. There is also the risk that during adverse market conditions, an instrument which would usually operate as a hedge provides no hedging benefits at all. The Fund’s use of derivatives may be limited by the requirements for taxation of the Fund as a regulated investment company.
Event Driven Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Event-Driven Trading Risk. Event-driven trading involves the risk that the special situation may not occur as anticipated, in which case the Fund may realize losses.
Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Leverage Risk. The risk associated with securities transactions or practices that multiply small market movements into larger changes in value. The Fund derives substantially all of its short exposure from its investment in derivatives and other financial instruments that provide leveraged exposure, such as futures contracts. The Fund’s investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Because such instruments are an integral part of the Fund’s investment strategy, the use of such instruments may expose the Fund to potentially dramatic losses or gains in the value of its portfolio. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Fund’s return.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Liquidity Risk. The risk that certain securities or other instruments, such as derivatives, may be difficult or impossible for the Fund to sell or dispose of at the price at which the Fund has valued the security.
Multi Manager Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Multi-Manager Risk. The investment styles employed by sub-advisors may not be complementary. The multi-manager approach could result in a high level of portfolio turnover, resulting in higher brokerage expenses and increased tax liability from the Fund’s realization of capital gains.
Natural Resources Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Natural Resources Risk. Investments in companies that own or develop natural resources (e.g., exploring, mining, refining), or supply goods and services to such companies (e.g., drilling, processing, transporting, fabricating), expose the Fund to the greater volatility of the markets for these companies’ products, and to international economic, political and regulatory influences that frequently affect the operation of these companies.
Options and Futures Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Options and Futures Risk. When options are purchased over the counter, the Fund bears the risk that the counterparty that wrote the option will be unable or unwilling to perform its obligations under the option contract. Such options may also be illiquid, and in such cases, the Fund may have difficulty closing out its position. The risks associated with futures include: the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.
Over the Counter OTC Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •  
Over-the-Counter (“OTC”) Trading Risk. Certain of the derivatives in which the Fund may invest, including
    swap agreements, may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty risk with respect to such derivatives contracts.
Swap Agreement Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Swap Agreement Risk. With respect to an uncleared swap (i.e., negotiated bilaterally and traded OTC between the two parties), the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. Under certain market conditions, swap agreements also may be considered to be illiquid. In addition, the Fund may enter into swap agreements that involve a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties are willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment goal. In the case of a cleared swap (i.e., transacted through a futures commission merchant (an “FCM”) and cleared through a clearinghouse that serves as a central counterparty (e.g., certain credit default swaps)), there is also a risk of loss by the Fund of the margin deposits posted with the FCM in the event of the FCM’s bankruptcy.
Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Valuation Risk. The risk that the Fund has valued certain of its securities at a higher price than it can sell them.
Active Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  •   Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance and increasing the amount of taxes that you pay).
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency.
