|---|---|
| Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. |
| Risk Not Insured [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, SIMC or any of its affiliates. |
| Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is non-diversified, which means that it may invest in the securities of relatively few issuers. As a result, the Fund may be more susceptible to a single adverse economic or political occurrence affecting one or more of these issuers and may experience increased volatility due to its investments in those securities. However, the Fund intends to satisfy the asset diversification requirements under the Internal Revenue Code of 1986, as amended (the Code) for classification as a regulated investment company (RIC). |
| Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. |
| Quality Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Quality Securities Risk. There is no guarantee that the past performance of stocks that SIMC determines are quality will continue. Companies that issue these stocks may experience lower than expected returns or may experience negative growth, as well as increased leverage, resulting in lower than expected or negative returns to Fund shareholders. Many factors can affect a stock's quality and performance, and the impact of these factors on a stock or its price can be difficult to predict. |
| Momentum Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Momentum Securities Risk. Stocks that previously exhibited high momentum characteristics may not experience positive momentum or may experience more volatility than the market as a whole. |
| Value Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Securities Risk. Securities issued by companies that may be perceived as undervalued may fail to appreciate for long periods of time and may never realize their full potential value. SIMC may be unsuccessful in identifying undervalued securities. Value securities may go in and out of favor over time. |
| Quantitative Investing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Quantitative Investing Risk. Due to the significant role technology plays in quantitative strategies, they carry the risk of unintended or unrecognized issues or flaws in the design, coding, implementation or maintenance of the computer programs or technology used in the development and implementation of the quantitative strategy. Utility interruptions or other key systems outages also can impair the performance of quantitative investment strategies. |
| Tracking Error Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tracking Error Risk. The risk that the Fund's performance may vary substantially from the performance of the benchmark index it tracks as a result of cash flows, Fund expenses, imperfect correlation between the Fund's investments and the benchmark and other factors. |
| Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market value of a security may move up and down, sometimes rapidly and unpredictably. Market risk may affect a single issuer, an industry, a sector or the equity or bond market as a whole. The Fund's market price may deviate from the value of the Fund's underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the Fund shares bought or sold. This can be reflected as a spread between the bid and ask prices for the Fund quoted during the day or a premium or discount in the closing price from the Fund's NAV. |
| Large Capitalization Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large Capitalization Risk. The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies. |
| Medium Capitalization Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Medium Capitalization Risk. The risk that medium capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, medium capitalization stocks may be more volatile than those of larger companies. Medium capitalization stocks may be traded over-the-counter (OTC). OTC stocks may trade less frequently and in smaller volume than exchange-listed stocks and may have more price volatility than that of exchange-listed stocks. |
| Investment Style Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Style Risk. The risk that the Fund's investment strategy may underperform other segments of the equity markets or the equity markets as a whole. |
| Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. The Fund's use of futures contracts is subject to leverage risk, correlation risk, liquidity risk and market risk. Market risk is described above, and leverage risk and liquidity risk are described below. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument. The Fund's use of derivatives may also increase the amount of taxes payable by shareholders. Both U.S. and non-U.S. regulators have adopted and implemented regulations governing derivatives markets, the ultimate impact of which remains unclear. |
| Risk of Investing in the U.S. [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Investing in the U.S. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure. |
| Issuer Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the Fund to decline. |
| Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. Active trading markets for the Fund's shares may not be developed or maintained by market makers or Authorized Participants (as defined below). Authorized Participants are not obligated to make a market in the Fund's shares or to submit purchase or redemption orders for Creation Units (as defined below). In times of market stress, market makers or Authorized Participants may step away from their respective roles, which could lead to variances between the market price of the Fund's shares and its underlying NAV. Trading in shares on an exchange may be halted in certain circumstances. If a trading halt occurs, a shareholder may temporarily be unable to purchase or sell shares of the Fund. Any of these factors could lead the Fund's shares to trade at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market, particularly during times of market stress. SIMC cannot predict whether shares will trade above (premium), below (discount) or at NAV or whether the spread between bid and ask prices will widen. In addition, there can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the Fund will continue to be met. |
| Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. SIMC may not successfully implement the Fund's investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies. |
| Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. |
| New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is a new fund, with a limited operating history, which may result in additional risks for investors in the Fund. There can be no assurance that the Fund will grow to an economically viable size, in which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer their investments at an inopportune time. |
| Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participant Concentration Risk. Only broker-dealers (referred to as Authorized Participants or APs) that have executed authorized participation agreements with respect to the Trust may engage in creation or redemption transactions directly with the Fund, and no AP is obligated to engage in creation and/or redemption transactions. To the extent that APs exit the business or are unable to proceed with orders, Fund shares may be more likely to trade at a premium or discount to NAV, have wider spreads between bid and ask prices, have wider spreads between bid and ask prices or face trading halts or delisting. |
| Cybersecurity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund, SIMC, the Fund's distributor, and other service providers, market makers, APs or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund's business operations and/or potentially result in financial losses to the Fund and its shareholders. |
| Index-Related Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index-Related Risk. The Fund seeks investment results that correspond generally to the performance, before fees and expenses, of the Underlying Index as published by the Index Provider. There is no assurance that the Index Provider will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. The Index Provider may cease publication of the Underlying Index or may terminate the license agreement allowing the Fund to use the Underlying Index, either of which could have a material adverse effect on the Fund. Market disruptions could cause delays in the Underlying Index's reconstitution and rebalancing schedule. During any such delay, it is possible that the Underlying Index and, in turn, the Fund will deviate from the Underlying Index's stated methodology and therefore experience returns different than those that would have been achieved under a normal reconstitution and rebalancing schedule. Generally, the Index Provider does not provide any warranty, or accept any liability, with respect to the quality, accuracy or completeness of the Underlying Index or its related data, and does not guarantee that the Underlying Index will be in line with its stated methodology. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its stated methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. The Advisor may have limited ability to detect such errors and neither the Advisor nor its affiliates provide any warranty or guarantee against such errors. Therefore, the gains, losses or costs associated with the Index Provider's errors will generally be borne by the Fund and its shareholders. Index-related risk may be higher for a fund that tracks an index comprised of, or an index that includes, foreign securities because regulatory and reporting requirements may differ from those in the US, resulting in a heightened risk of errors in the index data, index computation and/or index construction due to unreliable, outdated or unavailable information. |
| Index Licensing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Licensing Risk. It is possible that the index license, to which an affiliate of SIMC is the licensee and under which the Adviser or the Fund is permitted to use the index, will be terminated or may be disputed, impaired or cease to remain in effect. In such a case, the Adviser may be required to replace the index with another index which it considers to be appropriate in light of the investment strategy of the Fund. The use of any such substitute index may have an adverse impact on the Fund's performance. In the event that the Adviser is unable to identify a suitable replacement for the index, it may determine to terminate the Fund. |
| Index Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Risk. Although the Adviser has licensed from the Index Provider the right to use the Underlying Index as part of implementing the Fund's principal investment strategies, there can be no guarantee that the Underlying Index will be maintained indefinitely or that the Fund will be able to continue to utilize the Underlying Index to implement the Fund's principal investment strategies indefinitely. If the Index Provider ceases to maintain the Underlying Index, the Fund no longer has the ability to utilize the Underlying Index to implement its principal investment strategies, or other circumstances exist that the Adviser or the Fund's Board of Trustees concludes substantially limit the Fund's ability to gain investment exposure to the Underlying Index, the Adviser or the Fund's Board of Trustees may substitute the Underlying Index with another index that it chooses in its sole discretion and upon 60 days' prior written notice to shareholders. There can be no assurance that any substitute index so selected will be similar to the Underlying Index or will perform in a manner similar to the Index. Unavailability of the Underlying Index could affect adversely the ability of the Fund to achieve its investment objective. |
| Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund's investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes. |
