Benchmark Metrics

AltShares Merger Arbitrage ETF has an annualized alpha of 2.80%, beta of 0.08, and R2 of 0.10 versus S&P 500 Index. Calculated based on daily prices since May 07, 2020.

  • This ETF captured 8.08% of S&P 500 Index gains and tended to rise during its downturns (downside capture of -7.04%) - a profile typical of hedging or uncorrelated assets.
  • Beta of 0.08 may look defensive, but with R2 of 0.10 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 0.10 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.
