Benchmark Metrics
munger has an annualized alpha of 7.09%, beta of 0.66, and R² of 0.37 versus S&P 500 Index. Calculated based on daily prices since May 10, 1996.
- This portfolio participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (78.97%) than losses (60.77%) — typical of diversified or defensive assets.
- Beta of 0.66 may look defensive, but with R² of 0.37 this portfolio 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 portfolio's risk.
- R² of 0.37 means the benchmark explains less than half of this portfolio's behavior — treat beta with caution or consider switching to a more representative benchmark.
