Benchmark Metrics
PIMCO Corporate & Income Opportunity Fund has an annualized alpha of 7.15%, beta of 0.60, and R² of 0.23 versus S&P 500 Index. Calculated based on daily prices since December 27, 2002.
- This fund participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (88.46%) than losses (77.29%) — typical of diversified or defensive assets.
- Beta of 0.60 may look defensive, but with R² of 0.23 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 0.23 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.
