Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

The AAMA Equity Fund returned 23.81% for the twelve months ended June 30, 2026. This may be compared to the S&P 500® Index return of 22.32% and the S&P 500® Equal Weight Index return of 19.20%. The S&P MidCap 400® and SmallCap 600® indices returned 25.87% and 37.49%, respectively.

 

The difference between the capitalization-weighted and equal-weighted indices has narrowed from January to June 2026, although large cap technology issues, led by semi-conductor companies continue to dominate recent market returns.

 

Relative to the Equal-Weighted S&P 500®, The AAMA Equity Fund equity holdings experienced a 8.6% active return contribution over the last twelve months and 23.3% over the last three years. Sector allocations have impacted the active return modestly (1.70% for 1 year and 3.22% over three years). Stock selection boosted active returns by 6.89% for 1 year and 20.13% over three years. The Fund has been over-weight technology and communications companies and under-weight financial companies. The AAMA Equity Fund continues to maintain a portfolio of high-quality large cap companies. One key measure of quality is the Debt to EBITDA ratio. The Fund’s equity holdings average 2.29 times leverage, which is significantly less than the 4.00 leverage for a universe of 1100 large companies.

 

We appreciate your investment in our Funds and encourage you to continue to work with your Financial Advisor in allocating your portfolio to achieve your long-term investment goals and objectives.

Factors Affecting Performance [Text Block]

How did the Fund perform during the reporting period? 

For the twelve months ended June 30, 2026, the Large Cap Equity Fund Class AMF Shares returned 18.08% while the S&P 500® Index (Total Return) generated 22.32%. The Morningstar Large Blend category average returned 20.23%. According to Morningstar, this places the Fund in the top 68% of all Large Cap Blend stock funds for the past year. For the three-and-five year periods ended June 30, 2026, the Fund ranked in the 78th percentile and the 51st percentile, respectively, of the Morningstar Large Blend Category.

 

For the twelve months ended June 30, 2026, high yield, value and low volatility stocks underperformed the benchmark while momentum and growth outperformed. Since the Fund is oriented to value and higher than average dividend yield, this primarily caused the underperformance vs the benchmark.

 

The Fund’s investment adviser, System Two Advisors, continues to prefer companies with low share prices relative to cash flow and sales, and higher than average dividend yields. These are factors that we believe provide more stability and less volatility when markets underperform. In fact, the Fund continues to generate lower return volatility than the S&P 500® Index as well as the average fund in the Morningstar Large Blend category. The Fund’s investment adviser, System Two Advisors, relies on a blend of fundamental and quantitative analysis. We believe that the investment process of System Two Advisors provides an attractive risk-adjusted approach for our shareholders.
