  • This fund participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (45.82%) than losses (33.72%) — typical of diversified or defensive assets.
  • Beta of 0.11 may look defensive, but with R² of 0.07 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 0.07 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.
