Benchmark Metrics
Base11 has an annualized alpha of 3.17%, beta of 0.47, and R² of 0.42 versus S&P 500 Index. Calculated based on daily prices since July 29, 2002.
- This portfolio participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (45.49%) than losses (37.51%) — typical of diversified or defensive assets.
- Beta of 0.47 may look defensive, but with R² of 0.42 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 0.42 means the benchmark explains less than half of this portfolio's behavior — treat beta with caution or consider switching to a more representative benchmark.
