| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance For the fiscal year, the S&P 500 was driven higher by a handful of mega-cap stocks primarily residing in the Information Technology and Communication Services sectors. The S&P 500 returned 24.56%. However, the S&P 500 Top Ten Index experienced a much higher return of 39.99%. A less top-heavy version of the index, the S&P 500 Equal Weight, returned 11.79%. As of June 30, 2024, the Fund's one year return of 5.00% is primarily attributable to 1) its underweight position in Information Technology and Communication Services and 2) owning only one stock (Microsoft) that was a top ten constituent of the S&P 500. |
