Factors Affecting Performance [Text Block]  
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
The Fund delivered strong absolute returns during the Period despite market volatility marked by geopolitical turmoil in the Middle East and Technology sector concerns linked to AI disruption. Positive performance is attributed to regional asset allocation decisions—particularly in Emerging Markets—driven by attractive valuations and a broadening of the AI ecosystem across global supply chains.

Sector positioning and disciplined valuation management within the Technology and Communication Services sectors positively influenced performance. During the Period, the Fund reduced exposure to certain AI beneficiaries and technology-adjacent names trading at elevated valuations and reallocated to broad-based, quality-factor strategies across market caps. Later in the Period, tactical style shifts in Emerging Markets also contributed to strength by balancing legacy growth positions with value positions. Notable detractors came from individual stocks in the Healthcare sector driven by dampening forecasts for medical device volumes and waning sentiment on biotech drug pipelines.
