Benchmark Metrics

William Blair Emerging Markets Small Cap Growth Fund has an annualized alpha of 3.44%, beta of 0.54, and R2 of 0.35 versus S&P 500 Index. Calculated based on daily prices since October 26, 2011.

  • This fund participated in 77.60% of S&P 500 Index downside but only 72.13% of its upside - more exposed to losses than it benefited from rallies.
  • Beta of 0.54 may look defensive, but with R2 of 0.35 this fund is largely uncorrelated with S&P 500 Index - low beta reflects independence, not downside protection. See the Volatility section for a true picture of this fund's risk.
  • R2 of 0.35 means the benchmark explains less than half of this fund's behavior - treat beta with caution or consider switching to a more representative benchmark.
