Benchmark Metrics

Harbor Scientific Alpha Income ETF has an annualized alpha of 0.52%, beta of 0.16, and R² of 0.32 versus S&P 500 Index. Calculated based on daily prices since September 17, 2021.

  • This ETF participated in 33.88% of S&P 500 Index downside but only 23.13% of its upside — more exposed to losses than it benefited from rallies.
  • Beta of 0.16 may look defensive, but with R² of 0.32 this ETF 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 ETF's risk.
  • R² of 0.32 means the benchmark explains less than half of this ETF's behavior — treat beta with caution or consider switching to a more representative benchmark.
