Strategy Narrative [Text Block]	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in a broadly diversified portfolio of equity investments in small-cap U.S. issuers, including foreign issuers that are traded in the United States. Small-cap issuers are companies with relatively small market capitalizations which are generally within the capitalization range of the Russell 2000® Index at the time of investment. As of December 31, 2025, the capitalization threshold of the Russell 2000® Index was between $13.7 million and $26 billion; however, this capitalization range will change over time and with market conditions. The Fund may also invest in securities outside of the then-existing small-cap issuer capitalization range of companies constituting the Russell 2000® Index at the time of investment. The Fund uses a quantitative style of management, in combination with a qualitative overlay, that emphasizes fundamentally-based stock selection, careful portfolio construction and efficient implementation. The Fund’s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Fundamental Mispricings, High Quality Business Models, Sentiment Analysis and Market Themes & Trends. Fundamental Mispricings seeks to identify high-quality businesses trading at a fair price, which the Investment Adviser believes leads to strong performance over the long-run. High Quality Business Models seeks to identify companies that are generating high-quality revenues with sustainable business models and aligned management incentives. Sentiment Analysis seeks to identify stocks experiencing improvements in their overall market sentiment. Market Themes and Trends seeks to identify companies positively positioned to benefit from themes and trends in the market and macroeconomic environment. As a part of the Investment Adviser’s investment selection process, the Investment Adviser utilizes proprietary models that assess a wide range of indicators, which may include certain environmental, social and governance (“ESG”) indicators. No one indicator, risk or consideration is determinative in the investment selection process. The Fund may make investment decisions that deviate from those generated by the Investment Adviser’s proprietary models, at the discretion of the Investment Adviser. In addition, the Investment Adviser may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the Investment Adviser’s proprietary research. The Fund may also invest in fixed income securities that are considered to be cash equivalents. The Investment Adviser measures the Fund’s performance against the Russell 2000® Index.
