Benchmark Metrics

iShares Core FTSE 100 UCITS ETF GBP (Dist) has an annualized alpha of 3.36%, beta of 0.49, and R² of 0.25 versus S&P 500 Index. Calculated based on daily prices since November 29, 2016.

  • This ETF participated in 80.34% of S&P 500 Index downside but only 70.67% of its upside — more exposed to losses than it benefited from rallies.

  • R² of 0.25 means this ETF moves largely independently of S&P 500 Index — capture ratios reflect limited market correlation rather than active downside protection. Consider using a more representative benchmark.
