Benchmark Metrics
iShares MSCI World Mid-Cap Equal Weight UCITS ETF has an annualized alpha of 1.93%, beta of 0.52, and R² of 0.32 versus S&P 500 Index. Calculated based on daily prices since October 07, 2014.
- This ETF participated in 96.59% of S&P 500 Index downside but only 82.34% of its upside — more exposed to losses than it benefited from rallies.
- Beta of 0.52 may look defensive, but with R² of 0.32 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 0.32 means the benchmark explains less than half of this ETF's behavior — treat beta with caution or consider switching to a more representative benchmark.
