Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<span style="color:#000000;font-family:Arial;font-size:9.5pt;">Portfolio Turnover</span>
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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund’s shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table.

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests primarily in U.S. common stocks with the potential to generate higher returns relative to the broad U.S. equity market by investing in stocks with strong fundamentals 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 strong fundamentals subject to a rules-based screen designed to promote diversification and to mitigate exposure to certain less liquid stocks. Securities with relatively strong fundamentals may be identified by measures such as strong profitability, sustainable earnings, and healthy balance sheets. Under normal circumstances, at least 80% of the Fund’s assets will be invested in securities issued by U.S. companies.
