Strategy Narrative [Text Block]	The Fund employs an active management approach, investing primarily in U.S. common stocks with the potential to generate higher returns relative to the broad U.S. equity market by selecting stocks with relatively lower share prices relative to fundamental values as determined by the advisor. The Fund’s portfolio includes a diverse mix of companies representing many different market sectors and industry groups. The advisor uses a quantitative model to evaluate all of the securities in an investment universe comprised of U.S. large-, mid-, and small-capitalization stocks and to construct a U.S. equity portfolio that seeks to achieve exposure to securities with lower prices relative to fundamental measures of value subject to a rules-based screen designed to promote diversification and to mitigate exposure to certain less liquid stocks. Securities with lower prices relative to fundamental value may be identified by measures such as book to price and earnings to price ratios. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities issued by U.S. companies.
