In 2025, active stock fund managers have experienced mixed performance relative to their benchmarks. Year-to-date data shows that 50% of US large-cap mutual funds have outperformed their benchmarks, marking the highest share since the 2022 bear market and the second-best year in 16 years. However, longer-term data presents a contrasting picture. According to SPIVA statistics, over the past three years, 85% of large-cap active funds have underperformed their benchmarks, with 80-90% of active fund managers failing to beat their benchmarks over the last decade. Specifically, underperformance rates against the S&P 500 stand at 65.24% over one year, 84.96% over three years, 76.26% over five years, 84.34% over ten years, and 89.50% over fifteen years. These figures indicate that while short-term results in 2025 have been relatively favorable for active managers, the prevailing trend over longer periods continues to favor passive index benchmarks.
