Factors Affecting Performance [Text Block]  
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
For the Period, the Fund outperformed its benchmarks returning 27.35% (based on NAV) during the period while the Russell 1000 Value® Index and S&P 500® Index returned 27.09% and 22.32%, respectively. The Fund’s outperformance was due to a combination of sector weightings and good stock selection. Sector weightings reflect the Sub-Adviser’s highest-conviction positioning. These stocks did well because they delivered good earnings and positive outlooks for their businesses going forward.
The largest contributors to the Fund’s performance during the Period were stocks in the Technology, Industrials, Financials, and Communications Services sectors. Specifically, our Technology names benefited from investor’s enthusiasm over the build out of AI, with the semiconductor and chip companies, Applied Materials, Qualcomm, and Texas Instruments among our top performing stocks. In Industrials, FedEx and Generac were the top performers. FedEx has been revitalized under new senior management and Generac is seeing strong new business supplying back up power for data centers. In Financials, the bull market lifted Goldman Sachs and Morgan Stanley who showed strong results from trading, wealth management and investment banking. In Communication Services, Alphabet was a standout performer, receiving positive reviews for its AI capabilities.
Detractors from performance were stocks in the Consumer Discretionary and Consumer Staples sectors. The lackluster performance from these sectors was more about investors gravitating to higher growth areas of the market rather than specific names.
The Sub-Adviser employs a bottom-up stock selection process. The portfolio is built stock by stock with risk controls to manage sector risk. The Sub Adviser does not attempt “to time the market” or mimic a benchmark. The Sub Adviser invests in where it finds the best opportunities for long-term capital appreciation, employing a rigorous valuation disciple on our purchase and sale decisions.
