Benchmark Metrics
Principal Inflation Protection Fund has an annualized alpha of 2.41%, beta of -0.03, and R2 of 0.01 versus S&P 500 Index. Calculated based on daily prices since January 03, 2005.
- This fund participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (11.67%) than losses (11.64%) - typical of diversified or defensive assets.
- Beta of -0.03 may look defensive, but with R2 of 0.01 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 0.01 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.
