Benchmark Metrics
Water Island Event-Driven Fund has an annualized alpha of 1.12%, beta of 0.16, and R2 of 0.31 versus S&P 500 Index. Calculated based on daily prices since September 30, 2010.
- This fund participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (14.95%) than losses (12.52%) - typical of diversified or defensive assets.
- Beta of 0.16 may look defensive, but with R2 of 0.31 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 0.31 means the benchmark explains less than half of this fund's behavior - treat beta with caution or consider switching to a more representative benchmark.
