Factors Affecting Performance [Text Block]
How did the Fund perform last year ?
  • For the 12-month period ended December 31, 2024, the Fund’s Service Shares returned 7.96%.
  • In comparison, the S&P SmallCap 600® Index (the “Index”) returned 8.70% for the same period.
What affected the Fund’s performance?
  • Small-cap equities posted positive returns amid resilient economic growth, moderating inflation, and rising corporate profits, but trailed larger-cap markets.
  • Growth-oriented stocks outperformed value-oriented shares due to the improving economic outlook, rising corporate profits, and the prospect of lower interest rates.
  • The best-performing small-cap sector was financials, which stood to benefit from the reduction in regulatory oversight promised by the incoming presidential administration, followed by industrials and communication services.
  • Only two sectors posted negative returns, with energy stocks hurt by volatile prices and information technology small caps lacking the resources to compete in the development of artificial intelligence.
  • The difference in returns between the Fund and the Index resulted primarily from transaction costs and operating expenses that are not reflected in index results.
