The Fund's Institutional Class generated a total return of 5.02% during the six months ended June 30, 2024. This compares to the 15.29% return of the Fund’s broad-based regulatory benchmark, the S&P 500 Index, and 6.17% return of the Fund’s secondary benchmark, the S&P Mid Cap 400 Index, during the same semiannual period. While the Fund delivered positive absolute returns, it underperformed the S&P 500 ® ® The Fund, given its mid-cap focus, did not own any of the mega-cap stocks i.e., the largest of the large-cap stocks, that drove the two strongest sector of the S&P 500 ® These detractors were partially offset by effective stock selection in the industrials sector, which contributed positively. Having underweighted allocations to real estate and materials—the two weakest sectors in the S&P 500 ® During the semiannual period, the Fund’s relative results were hurt most by not owning NVIDIA, whose shares rose approximately 150% during the semiannual period. Additionally, holding positions in swimming pool supplies and equipment distributor Pool and provider of critical decision support tools and solutions for the investment community MSCI detracted. Each experienced a double-digit share price decline. Among the individual stocks that contributed most positively to the Fund’s relative results were semiconductor-based power electronics solutions developer Monolithic Power Systems and aerospace, defense and electronic related products manufacturer HEICO. Each of these companies enjoyed a robust double-digit share price gain during the semiannual period due to stronger than expected operating performance. The Fund also benefited from not owning electric vehicle maker Tesla, whose shares experienced a double-digit share price decline during the semiannual period. | |
