Benchmark Metrics

Vanguard Extended Duration Treasury Index Fund has an annualized alpha of 9.33%, beta of -0.36, and R2 of 0.10 versus S&P 500 Index. Calculated based on daily prices since November 20, 2007.

  • This fund tended to rise when S&P 500 Index fell (downside capture of -20.20%), but participation in market rallies was also limited (-0.47%) - a profile typical of counter-cyclical assets.
  • Beta of -0.36 may look defensive, but with R2 of 0.10 this fund 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 fund's risk.
  • R2 of 0.10 means this fund 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.
