Dec. 31, 2025
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity Securities Risk - The value of equity securities held by the Fund may decline as a result of factors directly related to a company, a particular industry or industries, or general market conditions that are not specifically related to a company or an industry.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk - The value of the Fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting (or perceived to affect) specific issuers held by the Fund, particular industries represented in the Fund’s portfolio, or the overall securities markets. A variety of factors can increase the volatility of the Fund’s holdings and markets generally, including political or regulatory developments, recessions, inflation, deflation, rapid interest rate changes, bank failures, war or acts of terrorism, sanctions, tariffs, natural disasters, outbreaks of infectious illnesses or other widespread public health issues, general outlook for corporate earnings, or adverse investor sentiment generally. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors and industries more significantly than others. These adverse developments may cause broad declines in an issuer’s value due to short-term market movements or for significantly longer periods during more prolonged market downturns.
Large Size Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large-Size Company Risk - Large-size companies are generally more mature and may be unable to respond as quickly as smaller companies to new competitive challenges, such as changes in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.
Small Or Mid Cap Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Small- and Medium-Size Company Risk - The stocks of small- and medium-size companies often trade in lower volumes, may be less liquid, and are subject to greater or more unpredictable price changes than stocks of larger companies. Such companies may also have limited markets, financial resources or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments. Accordingly, stocks of small- and medium-size companies tend to be more sensitive to changing economic, market, and industry conditions, tend to be more volatile and less liquid than stocks of larger companies, especially over the short term, and are less likely to survive or accomplish their goals, with the result that the value of their stock could decline significantly. In addition, there may be less publicly available information concerning small- and medium-size companies upon which to base an investment decision.
Value Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Value Stock Risk - A value style of investing is subject to the risk that returns on value stocks are less than returns on other styles of investing or the overall stock market. Value stocks tend to trade at lower price-to-book and price-to-earnings ratios, which suggest the market as a whole views their potential future earnings as limited.
Growth Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Growth Stock Risk - A growth style of investing is subject to the risk that returns on growth stocks are less than returns on other styles of investing or the overall stock market. Growth stocks can be volatile for several reasons. Since they usually reinvest a high proportion of earnings in their own business, they may not pay the dividends usually associated with value stocks that can cushion their decline in a falling market. Also, since investors buy these stocks because of the expected superior earnings growth, earnings disappointments may result in sharp price declines.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk - The use of derivatives, including but not limited to futures contracts and forward foreign currency contracts, may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. These risks include imperfect correlations with underlying investments or the Fund’s other portfolio holdings, magnified losses resulting from leverage, counterparty risk, high price volatility, liquidity risk, segregation risk, valuation risk and legal restrictions.
Index Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Index Risk - Because the Keyridge sub-advised portion of the Fund is not actively managed but is designed to track the performance of the S&P 500 Index, investors should generally expect the value of the Keyridge sub-advised portion of the Fund to decline when the performance of the S&P 500 Index declines. There is no guarantee that the Fund will achieve a high degree of correlation to the S&P 500 Index. Additionally, the S&P 500 Index may perform unfavorably or underperform the market as a whole. As a result, the Keyridge sub-advised portion of the Fund may have poor investment results even if it closely tracks the performance of the S&P 500 Index because the adverse performance of a particular security normally will not result in eliminating the security from the Keyridge sub-advised portion of the Fund.
Tracking Error Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Tracking Error Risk - The Keyridge sub-advised portion of the Fund may not be able to precisely track the performance of the S&P 500 Index. Unlike the Keyridge sub-advised portion of the Fund, the performance of the S&P 500 Index is not impacted by fees and expenses, including trading costs associated with implementing portfolio changes. In addition, the Keyridge sub-advised portion of the Fund may own less than all the securities of the S&P 500 Index, which also may cause a variance between the performance of the Keyridge sub-advised portion of the Fund and the performance of the S&P 500 Index. Tracking error risk may cause the Keyridge sub-advised portion of the Fund’s performance to be less than expected.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk - A strategy, investment decision, technique, analysis, or model used by the portfolio managers may fail to produce the intended results, or imperfections, errors or limitations in the tools and data used by the portfolio managers may cause unintended results. Therefore, the Fund could underperform in comparison to other funds with similar objectives and investment strategies and may generate losses even in a favorable market.
Multi Manager Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Multi-Manager Risk - Because the Sub-Advisers make investment decisions independently, it is possible that their security selection processes may not complement one another, and the Fund may have buy and sell transactions in the same security on the same day.
Exchange Traded Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Exchange-Traded Fund Risk - Shares in an ETF represent an interest in a portfolio of securities generally designed to track the performance of a particular market index. The Fund could purchase shares issued by an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market, for example, while awaiting purchase of underlying securities. The risks associated with owning an ETF generally reflect the risks of owning the underlying securities it is designed to track, although ETFs have management fees that increase their costs. Fund shareholders indirectly bear their proportionate share of the expenses of the ETFs in which the Fund invests. An ETF may trade at a premium or discount, and, as a result, the Fund may pay more than net asset value when purchasing shares and receive less than net asset value when selling shares.
