- Beta of -0.06 may look defensive, but with R2 of 0.04 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 0.04 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.
