Benchmark Metrics

Quest Diagnostics Incorporated has an annualized alpha of 13.83%, beta of 0.62, and R2 of 0.16 versus S&P 500 Index. Calculated based on daily prices since December 26, 1996.

  • This stock participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (73.26%) than losses (32.73%) - typical of diversified or defensive assets.
  • Beta of 0.62 may look defensive, but with R2 of 0.16 this stock 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 stock's risk.
  • R2 of 0.16 means this stock 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.
