Capital Appreciation Fund Investment Risks - Capital Appreciation Fund
May 31, 2026
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk. The investment style or strategy used by the Fund may fail to produce the intended result. A subadviser’s assessment of a particular security or company may prove incorrect, resulting in losses or underperformance.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity Securities Risk. The Fund’s investments in equity securities are subject to the risk that stock prices will fall and may underperform other asset classes. Individual stock prices fluctuate from day-to-day and may decline significantly. The prices of individual stocks may be negatively affected by poor company results or other factors affecting individual prices, as well as industry and/or economic trends and developments affecting industries or the securities market as a whole.
Growth Style Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Growth Style Risk. Generally, “growth” stocks are stocks of companies that have anticipated earnings ranging from steady to accelerated growth. Many investors buy growth stocks because of anticipated superior earnings growth, but earnings disappointments often result in sharp price declines. Growth companies usually invest a high portion of earnings in their own businesses so their stocks may lack the dividends that can cushion share prices in a down market. In addition, the value of growth stocks may be more sensitive to changes in current or expected earnings than the value of other stocks, because growth stocks trade at higher prices relative to current earnings.
Large Cap Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large-Cap Companies Risk. Investing primarily in large-cap companies carries the risk that due to current market conditions these companies may be out of favor with investors. Large-cap companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rate of successful smaller companies, particularly during extended periods of economic expansion.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The Fund’s share price can fall because of weakness in the broad market, a particular industry, or specific holdings or due to adverse social, political or economic developments here or abroad, changes in investor psychology, technological disruptions, or heavy institutional selling and other conditions or events (including, for example, military confrontations, war, terrorism, trade wars, disease/virus outbreaks and epidemics). The prices of individual securities may fluctuate, sometimes dramatically, from day to day. The prices of stocks and other equity securities tend to be more volatile than those of fixed-income securities.
Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Technology Sector Risk. Technology stocks historically have experienced unusually wide price swings. Earnings disappointments and intense competition for market share can result in sharp declines in the prices of technology stocks.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Sector Risk. Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the risk that securities of companies within specific sectors of the economy can perform differently than the overall market. This may be due to changes in such things as the regulatory or competitive environment or to changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain sectors than others, the Fund’s performance may be more susceptible to any developments which affect those sectors emphasized by the Fund.
Securities Lending Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Securities Lending Risk. Engaging in securities lending could increase the market and credit risk for Fund investments. The Fund may lose money if it does not recover borrowed securities, the value of the collateral falls, or the value of investments made with cash collateral declines. The Fund’s loans will be collateralized by securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities, which subjects the Fund to the credit risk of the U.S. Government or the issuing federal agency or instrumentality. If the value of either the cash collateral or the Fund’s investments of the cash collateral falls below the amount owed to a borrower, the Fund also may incur losses that exceed the amount it earned on lending the security. Securities lending also involves the risks of delay in receiving additional collateral or possible loss of rights in the collateral if the borrower fails. Another risk of securities lending is the risk that the loaned portfolio securities may not be available to the Fund on a timely basis and the Fund may therefore lose the opportunity to sell the securities at a desirable price.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] If the value of the assets of the Fund goes down, you could lose money.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] Shares of the Fund are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation.
