Benchmark Metrics
Thornburg Summit Fund Class I has an annualized alpha of 5.54%, beta of 0.49, and R2 of 0.49 versus S&P 500 Index. Calculated based on daily prices since March 13, 2019.
- This fund participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (60.77%) than losses (55.14%) - typical of diversified or defensive assets.
- Beta of 0.49 may look defensive, but with R2 of 0.49 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 0.49 means the benchmark explains less than half of this fund's behavior - treat beta with caution or consider switching to a more representative benchmark.
