Benchmark Metrics

American Century Multisector Income ETF has an annualized alpha of 0.74%, beta of 0.12, and R2 of 0.19 versus S&P 500 Index. Calculated based on daily prices since July 01, 2021.

  • This ETF participated in 30.26% of S&P 500 Index downside but only 19.31% of its upside - more exposed to losses than it benefited from rallies.
  • Beta of 0.12 may look defensive, but with R2 of 0.19 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 0.19 means this ETF 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.
