Benchmark Metrics
Buffett Portfolio has an annualized alpha of 8.22%, beta of 0.47, and R2 of 0.35 versus S&P 500 Index. Calculated based on daily prices since May 14, 2019.
- This portfolio participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (87.96%) than losses (83.49%) - typical of diversified or defensive assets.
- Beta of 0.47 may look defensive, but with R2 of 0.35 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 0.35 means the benchmark explains less than half of this portfolio's behavior - treat beta with caution or consider switching to a more representative benchmark.
