Benchmark Metrics
Simplify National Muni Bond ETF has an annualized alpha of -1.10%, beta of 0.36, and R² of 0.21 versus S&P 500 Index. Calculated based on daily prices since September 11, 2024.
- This ETF participated in 46.39% of S&P 500 Index downside but only 28.87% of its upside — more exposed to losses than it benefited from rallies.
- Beta of 0.36 may look defensive, but with R² of 0.21 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 0.21 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.
