Benchmark Metrics

Buffet - Japanese Trading Companies has an annualized alpha of 3.85%, beta of 0.53, and R2 of 0.16 versus S&P 500 Index. Calculated based on daily prices since July 16, 2007.

  • This portfolio participated in 85.04% of S&P 500 Index downside but only 73.30% of its upside - more exposed to losses than it benefited from rallies.
  • Beta of 0.53 may look defensive, but with R2 of 0.16 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 0.16 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.
