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 34% of the average value of its portfolio.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund pursues its investment objective by investing primarily in the common stocks of small companies that are traded on national security exchanges, the NASDAQ stock market and on the over-the-counter market. Small companies will be defined as companies with market capitalizations that are between the lowest and highest market capitalizations, as measured on a rolling basis over the most recent 36-month period, in either the Russell 2000 Index (which had a rolling 36-month market capitalization range of $2.4 million to $17.3 billion as of October 31, 2020), the Standard & Poor’s Small Cap 600 Index (which had a rolling 36-month market capitalization range of $17.3 million to $13.8 billion as of October 31, 2020), or the MSCI USA Small Cap Index (which had a rolling 36-month market capitalization range of $26.52 million to $33.3 billion as of October 31, 2020).The Fund will normally invest at least 80% of its net assets (which include the amount of any borrowings for investment purposes) in investments in small companies and will notify shareholders at least 60 days in advance of any change in its investment policies that would permit the Fund to normally invest less than 80% of its net assets in investments in small companies. Such definition will be applied at the time of investment and the Fund will not be required to sell a stock because a company has grown outside the market capitalization range of small capitalization stocks.Up to 30% of the Fund’s net assets may be invested in foreign securities. When investing in foreign securities, the Fund’s Adviser and Sub-Adviser (collectively, “Adviser”) may emphasize investment in a particular country or group of countries which may subject the Fund to the risks of investing in such country or group of countries to a greater extent than if the Fund’s foreign security exposure was diversified over a greater number of countries. The Adviser’s process for selecting investments is bottom-up and growth-oriented. The Fund may loan up to 30% of its total assets in the form of its portfolio securities to unaffiliated broker/dealers, banks or other recognized institutional borrowers to generate additional income. The Fund receives cash, U.S. Treasury obligations and/or other liquid securities as collateral. The Fund also may invest up to 15% of its net assets in illiquid securities.The Fund may invest in fixed-income securities, American Depositary Receipts and use derivative contracts (such as, for example, options, swaps and futures contracts) and/or hybrid instruments to implement elements of its investment strategy. For example, the Fund may use derivative contracts or hybrid instruments to increase or decrease the portfolio’s exposure to the investment(s) underlying the derivative or hybrid instruments 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 assurances the Fund’s use of derivative contracts and/or hybrid instruments will work as intended. Derivative investments made by the Fund are included within the Fund’s 80% policy and are calculated at market value.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:8.5pt;font-weight:bold;">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:◾ 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.◾ Risk Related to Investing for Growth. Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. For instance, the price of a growth stock may experience a larger decline on a forecast of lower earnings, a negative fundamental development, or an adverse market development. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.◾ Small-Cap Company Risk. The Fund may invest in small capitalization (or “small-cap”) companies. Small-cap companies may have less liquid stock, a more volatile share price, unproven track records, a limited product or service base, and limited access to capital. The above factors could make small-cap companies more likely to fail than larger companies, and increase the volatility of the Fund’s portfolio, performance and Share price. The Adviser and its affiliated investment advisers also can manage other funds and accounts that use small-cap or similar investment strategies, and investments in small-cap securities by multiple funds and accounts, including those managed by the Adviser and its affiliates, could impact the availability of suitable small-cap securities and cause a capacity constraint associated with the Fund’s small-cap investment strategy◾ Focused Investment Risk. To the extent that the Fund focuses its investments in the securities of a particular issuer or companies in a particular country, group of countries, region, market, industry, group of industries, sector, or asset class, the Fund’s exposure to various risks may be heightened, including price volatility and adverse economic, market, political, or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector, or asset class.◾ Liquidity Risk. Liquidity risk refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract 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.◾ Risk of Foreign Investing. Because the Fund invests in securities issued by foreign companies and national governments, 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 American Depositary Receipts 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.◾ Custodial Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive due to differing settlement and clearance procedures than those of the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. In addition, security settlement and clearance procedures in some emerging market countries may not fully protect the Fund against loss of its assets.◾ Currency Risk. Exchange rates for currencies fluctuate daily. Foreign securities are normally denominated and traded in foreign currencies. As a result, the value of the Fund’s foreign investments and the value of the shares may be affected favorably or unfavorably by changes in currency exchange rates relative to the U.S. dollar.◾ 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.◾ Risk of Investing in Derivative Contracts and Hybrid Instruments. Derivative contracts and hybrid instruments 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 and instruments 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 and hybrid instruments may also involve other risks described in this Prospectus such as stock market, credit, currency, liquidity and leverage risks.◾ Credit Risk. Credit risk includes the possibility that a party to a transaction (such as a derivative transaction) involving the Fund will fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.◾ 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.◾ Leverage Risk. Leverage risk is created when an investment (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.◾ Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. The longer the duration of a fixed-income security, the more susceptible it is to interest-rate risk. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.◾ 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.◾ Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective 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.
