Factors Affecting Performance [Text Block]
WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD?
US equities posted solid gains for the reporting period, supported by investor enthusiasm around artificial intelligence (AI), resilient corporate
earnings, and three Federal Reserve rate cuts later in the period. Volatility picked up late in the year amid renewed questions about AI-related
investment and elevated valuations, but moderating economic growth and ongoing adoption of AI-technologies helped sustain investor
confidence and risk appetite.
Positions in the information technology, communication services, financials, and industrials sectors were the largest contributors to the Fund’s
solid absolute performance during the reporting period. Relative to the S&P 500 Index, security selection in the industrials, healthcare, and
utilities sectors added the most value. The Fund’s overweight allocation to the communication services sector, combined with a lack of
exposure to the real estate and energy sectors, also benefited relative results.
While the Fund delivered solid absolute performance in 2025, returns lagged the S&P 500 Index for the period. Relative underperformance was
largely driven by stock selection within the information technology, communication services, consumer discretionary, and financials sectors. The
Fund’s overweight allocation to the consumer discretionary sector and underweight allocation to the healthcare sector also acted as headwinds
to relative pe
rform
ance.
