| Portfolio Turnover [Text Block] | The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio).

During the most recent fiscal year, the fund's portfolio turnover rate was 56 % of the average value of its portfolio. | |||||||||||||||||

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated and if you hold your shares: | |||||||||||||||||
| Strategy [Heading] | Principal Investment Strategies | |||||||||||||||||
| Strategy Narrative [Text Block] | Normally investing at least 80% of assets in equity securities. Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Equity securities include common stocks (including depositary receipts evidencing ownership of common stock), preferred stocks and other preferred securities, convertible securities, rights and warrants, and other securities, such as hybrid securities and trust preferred securities, believed to have equity-like characteristics. Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Investing in common stocks of companies with market capitalizations generally similar to companies in the S&P 500® Index. Using a disciplined approach designed to construct an equity portfolio with similar risk-return characteristics to the S&P 500® Index. Employing a disciplined options-based strategy designed to provide downside protection in certain market conditions (i.e., offset or mitigate a decrease in the value of the fund's investments). The extent of this protection will be determined primarily based on the cost of the put options in the marketplace. Managing the options positions in a way that provides diversification of options strike prices and expirations. | |||||||||||||||||
