| Factors Affecting Performance [Text Block] | MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE For the period December 31, 2023 through December 31, 2024 the total return of the Fund was up 12.53% versus the S&P 500 up 25.02% and the S&P 500 High Dividend ETF which was up 15.32%. The S&P 500 has been meaningfully driven by a handful of large cap technology stocks with high valuation levels and virtually no dividend income, both of which are inconsistent with the strategy of the Fund. Our performance will lag when these Technology stocks significantly outperform. We are confident that money will flow back toward value and income stocks and our portfolio should perform relatively well, especially if interest rates decline. The turnover of the Fund in 2024 was below average expectations at 3.74% as we did not feel compelled to realize capital gains only to pay tax and then invest in other high dividend paying opportunities. We liked our portfolio in 2024. The Fund continues to hold what we feel are very high quality companies with stable cash flows and relatively conservative and transparent balance sheets. The Fund begins 2025 with a meaningfully above market internal portfolio dividend yield and strong cash flows which we would expect to perform well going forward. Sincerely, Steven Adams Portfolio Manager | |
