Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 148% of the average value of its portfolio.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund pursues its investment objective primarily through short positions in domestically traded equity securities and indices. The Fund holds short-term liquid securities such as money market funds, U.S. Treasury securities, government agency securities or other equity securities for liquidity purposes and to cover the Fund’s obligation to purchase securities subject to short sales in the future. The Fund also seeks capital appreciation through long positions on equity securities which the Fund’s Adviser believes are undervalued. The Fund may also invest, to a lesser extent, in securities of foreign issuers.The Adviser believes that the best opportunities to make both “short” and “long” equity investments are when the market’s perception of the values of individual companies (measured by the stock price) differs widely from the Adviser’s assessment of the intrinsic values of such companies. Such opportunities arise as a result of a variety of market inefficiencies, including, among others, imperfect information, overly optimistic or pessimistic forecasts by Wall Street analysts, and swings in investor psychology. These inefficiencies can cause substantially mispriced securities. The Fund’s “short” equity positions consist primarily of short sales of common stocks (which may include shares of ETFs), short sales of stock indices, short sales of stock index futures, purchases of put options on common stocks, purchases of put options on stock indices and purchases of put options on stock index futures. The Adviser will allocate the Fund’s portfolio between “short” equity and “long” equity positions at its discretion. At all times the Fund will have both “short” and “long” equity positions as the Adviser believes in all market conditions there will exist some companies whose stocks are undervalued by the market and some companies whose stocks are overvalued by the market. Long positions can consist both of individual long positions in stocks of companies, as well as long positions on futures instruments of stock market indices, call options on such indices and other related instruments.Under normal market conditions, the Fund will use leverage in implementing its investment strategies, and the aggregate exposure of the Fund’s short positions plus its long positions is expected to exceed the Fund’s net asset value. Normally, however, the Fund is expected to have more short exposure than long exposure on securities and/or the overall market, resulting in net short exposure.The Fund may invest in derivative contracts (such as, for example, options, swaps and futures contracts) to implement its investment strategies. For example, the Fund may use derivative contracts to increase or decrease the portfolio’s exposure to the investment(s) underlying the derivative in an attempt to benefit from changes in the value of the underlying investment(s), to realize gains from trading a derivative contract or to hedge against potential losses. There can be no assurance that the Fund’s use of derivative contracts will work as intended. The Fund can also purchase ETFs.The Adviser actively manages the Fund’s portfolio. The Fund’s annual portfolio turnover rate usually will exceed 100%.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:8.5pt;font-weight:bold;margin-left:0%;">What are the Main Risks of Investing in the Fund?</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:■  Short Selling Risk. The Fund can sell securities short to the maximum extent permitted under the Investment Company Act of 1940 (the “1940 Act”). A short sale by the Fund involves borrowing a security from a lender which is then sold in the open market. At a future date, the security is repurchased by the Fund and returned to the lender. While the security is borrowed, the proceeds from the sale are deposited with the lender and the Fund may be required to pay interest and/or the equivalent of any dividend payments paid by the security to the lender. If the value of the security declines between the time the Fund borrows the security and the time it repurchases and returns the security to the lender, the Fund makes a profit on the difference (less any expenses the Fund is required to pay the lender). There is no assurance that a security will decline in value during the period of the short sale and make a profit for the Fund. If the value of the security sold short increases between the time that the Fund borrows the security and the time it repurchases and returns the security to the lender, the Fund will realize a loss on the difference (plus any expenses the Fund is required to pay to the lender). This loss is theoretically unlimited as there is no limit as to how high the security sold short can appreciate in value, thus increasing the cost of buying that security to cover a short position. The Fund may incur expenses in selling securities short and such expenses are investment expenses of the Fund.■  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. Information publicly available about a company, whether from the company’s financial statements or other disclosures or from third parties, or information available to some but not all market participants, can affect the price of a company’s shares in the market. Among other factors, equity securities may decline in value because of an increase in interest rates or changes in the stock market. Recent and potential future changes in industry and/or economic trends, as well as changes in monetary policy made by central banks and/or their governments, also can affect the level of interest rates and contribute to the development of or increase in volatility, illiquidity, shareholder redemptions and other adverse effects (such as a decline in a company’s stock price), which could negatively impact the Fund’s performance.■ Initial Public Offerings Risk. IPOs are initial public offerings of equity securities. Securities issued in IPOs have no trading history, and there may only be limited information about the companies. In addition, the prices of securities sold in IPOs may be highly volatile and may rise or fall shortly after an IPO.■  Asset Allocation Risk. The Fund’s investment results will suffer if there is a general stock market advance when the Fund has significant “short” equity positions, or if there is a general stock market decline when the Fund has significant “long” equity positions. This risk is in addition to the market risks associated with each of the Fund’s investments. In certain conditions, the Funds may employ risk management strategies. No risk management strategies can eliminate the Fund’s exposure to adverse events; at best, they can only reduce the possibility that the Fund will be affected by such events, and especially those risks that are not intrinsic to the Fund’s investment program. There can be no guarantee that the Adviser will be successful in its attempts to manage the risk exposure of the Fund.■  Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.■ Risk of Investing in Derivative Contracts. Derivative contracts involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts include valuation and tax issues, increased potential for losses and/or costs to the Fund and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts may also involve other risks described in this Prospectus, such as stock market, credit, currency, liquidity and leverage risks.■ Leverage Risk. Leverage risk is created when an instrument (such as a derivative transaction) exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.■ Risk Related to Investing for Value. Due to their relatively low valuations, value stocks are typically less volatile than growth stocks. For instance, the price of a value stock may experience a smaller increase on a forecast of higher earnings, a positive fundamental development or positive market development. Further, value stocks tend to have higher dividends than growth stocks. This means they depend less on price changes for returns and may lag behind growth stocks in an up market.■ Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Economic, political and financial conditions, industry or economic trends and developments or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, cause the Fund to experience volatility, illiquidity, shareholder redemptions or other potentially adverse effects.■ Liquidity Risk. The equity securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. Liquidity risk also refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract or short sale when it wants to. If this happens, the Fund will be required to continue to hold the security or keep the position open, and the Fund could incur losses. OTC derivative contracts generally carry greater liquidity risk than exchange-traded contracts.■ Exchange-Traded Funds Risk. An investment in an exchange-traded fund (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.■ Risk of Foreign Investing. Because the Fund may invest in securities issued by foreign companies, the Fund’s Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case.■ Risk of Investing in ADRs and Domestically Traded Securities of Foreign Issuers. Because the Fund may invest in ADRs and other domestically traded securities of foreign companies, the Fund’s share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.■ Currency Risk. Exchange rates for currencies fluctuate daily. The combination of currency risk and market risk tends to make securities traded in foreign markets more volatile than securities traded exclusively in the United States.■ European Union and Eurozone Related Risk. A number of countries in the European Union (EU), including certain countries within the EU that have adopted the euro (Eurozone), have experienced, and may continue to experience, severe economic and financial difficulties. Additional countries within the EU may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund’s investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.■ Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective(s) and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
