Benchmark Metrics

1 - optimised has an annualized alpha of 3.52%, beta of 0.41, and R2 of 0.27 versus S&P 500 Index. Calculated based on daily prices since July 25, 2019.

  • This portfolio participated in 56.88% of S&P 500 Index downside but only 54.11% of its upside - more exposed to losses than it benefited from rallies.
  • Beta of 0.41 may look defensive, but with R2 of 0.27 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 0.27 means this portfolio 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.
