| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? Emerging markets equities advanced over the 12-month reporting period. Hopes that the U.S. Federal Reserve would begin lowering interest rates, alongside broadly favorable corporate earnings and investor enthusiasm about prospects for artificial intelligence (AI), supported sentiment. All regions ended higher, with Asia leading the gains. The industrials and business services sector contributed the most to relative returns against the MSCI Emerging Markets Index Net. Singapore-listed Yangzijiang Shipbuilding and Brazilian aircraft manufacturer Embraer were significant contributors on solid earnings and upbeat forecasts. Stock selection in China also contributed to relative performance. Standouts included travel platform Trip.com, which performed well amid an improving outlook for travel demand, and property brokerage KE Holdings, which gained after Beijing unveiled measures to support the real estate sector. Security selection in information technology (IT) detracted the most from relative returns. South Korean tech giant Samsung Electronics was a large detractor due to disappointing earnings and worries that memory chip prices may be nearing a peak. Stock selection in financials also detracted from relative performance. The portfolio invests in undervalued, “forgotten” stocks with asymmetrical risk/reward potential and identifiable fundamental improvement drivers. Over the year, we raised our allocations to IT and utilities, investing in attractive opportunities across several Asian markets. Conversely, our exposure to consumer staples and materials companies decreased. | |||
