Benchmark Metrics

T-REX 2X Inverse MSTR Daily Target ETF has an annualized alpha of -18.72%, beta of -4.77, and R² of 0.22 versus S&P 500 Index. Calculated based on daily prices since September 19, 2024.

  • This ETF participated in 401.50% of S&P 500 Index downside but only -199.05% of its upside — more exposed to losses than it benefited from rallies.
  • Beta of -4.77 may look defensive, but with R² of 0.22 this ETF 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 ETF's risk.
  • R² of 0.22 means this ETF 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.
