Benchmark Metrics
iShares U.S. Utilities ETF has an annualized alpha of 4.55%, beta of 0.61, and R2 of 0.39 versus S&P 500 Index. Calculated based on daily prices since June 20, 2000.
- This ETF participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (60.48%) than losses (49.96%) - typical of diversified or defensive assets.
- Beta of 0.61 may look defensive, but with R2 of 0.39 this ETF 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 ETF's risk.
- R2 of 0.39 means the benchmark explains less than half of this ETF's behavior - treat beta with caution or consider switching to a more representative benchmark.
