Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
The Fund’s investment strategy seeks both capital appreciation and a high level of dividend income. During the Period, the Fund underperformed the broader U.S. equity market as elevated interest rates weighed on dividend-oriented equities, while market gains remained concentrated in large technology companies benefiting from increased investment in artificial intelligence (AI).

Dividend stocks continued to face headwinds from elevated interest rates as money market yields and other fixed income investments provided income-seeking investors with attractive alternatives. Higher borrowing costs also pressured capital-intensive and leverage-sensitive companies by increasing interest expense and limiting capital available for investment, expansion, and dividend growth. Meanwhile, AI-related infrastructure spending remained comparatively strong, contributing to a widening divergence in growth between AI-related businesses and more traditional segments of the economy.
This divergence was particularly meaningful for the Fund because its investment universe requires companies to meet certain dividend criteria. Many technology companies benefiting from AI-related spending paid dividends below the Fund’s required threshold or did not pay dividends at all, making them ineligible for investment. As a result, the Fund maintained greater exposure to mature, dividend-paying businesses that generally experienced slower growth. Some of these companies also faced pressure as investors assessed the potential for AI to disrupt their industries or limit future growth prospects, even though those risks had not yet materially affected underlying operating results.

Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
The Fund’s investment strategy seeks capital appreciation. During the Period, the Fund benefited from a market environment characterized by several strong momentum trends. These included companies tied to artificial intelligence (AI) infrastructure, semiconductors, and cloud computing, where the Fund's quantitative process identified companies exhibiting strengthening price momentum. The Fund also captured positive trends across the Industrials, Communication Services, and Financials sectors, helping broaden performance beyond the Technology sector.
AI-related infrastructure investment remained one of the strongest market themes during the Period as companies increased capital spending on computing infrastructure and other technology necessary to build and run AI models. The Fund’s quantitative investment process identified strengthening price momentum among companies benefiting from this spending, allowing the portfolio to participate as momentum built. Periodic concerns about the return on AI investment and the outlook for capital spending created volatility, but the broader trend remained relatively persistent.
