| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? • The Fund returned 13.37% for the year ended December 31, 2024. The Fund’s benchmark, the S&P 500® Index, returned 25.02% for the year ended December 31, 2024. • Moderating inflation, strong corporate earnings growth, expectations for interest rate cuts and other factors contributed to strong performance in the overall equity markets and benefited the Fund. • The Fund’s investment strategy focuses on portfolio diversification and therefore was underweight the relative small number of technology-related companies that drove the majority of the benchmark’s performance. • Stock selection decisions in the Materials, Energy and Financials sectors were the largest contributors to the Fund’s relative performance. • The Fund’s underweight positions in the Healthcare and Real Estate sectors also contributed to the Fund’s relative performance. • Stock selection decisions in the Information Technology, Consumer Staples, Consumer Discretionary and Industrials sectors were the largest detractors from the Fund’s relative performance. • The Fund’s overweight positions in the Materials and Energy sectors and underweight position in the Communication Services sector also detracted from the Fund’s relative performance. | |
