Factors Affecting Performance [Text Block] | How did the Fund perform last year? U.S. equities broadly moved higher as the period progressed, resulting in significant positive returns across most market segments. Fears of a U.S. recession waned while major overseas economies returned to positive growth. Signs of easing inflation led to expectations that the U.S. Federal Reserve and other leading central banks were poised to reduce interest rates, leading growth-oriented stocks to outperform value stocks. What contributed to performance? Positive contributions to performance, relative to the benchmark (Russell 1000 ® What detracted from performance? The largest detractors from relative performance included stock selection in financials, along with positioning in communication services and selection in consumer discretionary. Within financials, an overweight to the capital markets industry, specifically overweight positions in market index provider MSCI and rating agency S&P Global, detracted from relative return. An underweight to communication services also weighed on performance, most notably an underweight position in Facebook operator Meta Platforms. Finally, in consumer discretionary an out-of-benchmark position in LVMH within the textiles, apparel and luxury goods sub-sector detracted from relative performance.
