Benchmark Metrics
T-REX 2X Inverse MSTR Daily Target ETF has an annualized alpha of 19.03%, beta of -4.88, and R2 of 0.23 versus S&P 500 Index. Calculated based on daily prices since September 18, 2024.
- This ETF participated in 361.74% of S&P 500 Index downside but only -164.42% of its upside - more exposed to losses than it benefited from rallies.
- Beta of -4.88 may look defensive, but with R2 of 0.23 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 0.23 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.
