Benchmark Metrics
SEI Asset Allocation Trust Defensive Strategy Allocation Fund has an annualized alpha of -1.75%, beta of 0.42, and R2 of 0.19 versus S&P 500 Index. Calculated based on daily prices since January 05, 2004.
- This fund participated in 81.65% of S&P 500 Index downside but only 45.73% of its upside - more exposed to losses than it benefited from rallies.
- Beta of 0.42 may look defensive, but with R2 of 0.19 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 0.19 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.
