Benchmark Metrics

T. Rowe Price U.S. Treasury Long Term Index Fund has an annualized alpha of 7.11%, beta of -0.12, and R2 of 0.04 versus S&P 500 Index. Calculated based on daily prices since January 02, 1990.

  • This fund captured 10.12% of S&P 500 Index gains and tended to rise during its downturns (downside capture of -16.10%) - a profile typical of hedging or uncorrelated assets.
  • Beta of -0.12 may look defensive, but with R2 of 0.04 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 0.04 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.
