Benchmark Metrics

Berkshire Hathaway has an annualized alpha of 6.46%, beta of 0.63, and R2 of 0.31 versus S&P 500 Index. Calculated based on daily prices since May 09, 1996.

  • This portfolio participates in less of S&P 500 Index's moves in both directions, but captures a larger share of gains (73.28%) than losses (59.74%) - typical of diversified or defensive assets.
  • Beta of 0.63 may look defensive, but with R2 of 0.31 this portfolio 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 portfolio's risk.
  • R2 of 0.31 means the benchmark explains less than half of this portfolio's behavior - treat beta with caution or consider switching to a more representative benchmark.

Sharpe Ratio

The Sharpe ratio helps investors understand how much return they're getting for the level of risk taken. A higher Sharpe ratio indicates better risk-adjusted performance, meaning more reward for each unit of risk.

The current Berkshire Hathaway Sharpe ratio is -0.02 as of Jun 13, 2026 (the value is recalculated daily), calculated over the past 12 months.

Compared to the broad market, where average Sharpe ratios range from 1.54 to 2.41, this portfolio's current Sharpe ratio places it in the bottom 25%. This suggests weaker risk-adjusted returns than most portfolios, possibly due to lower returns, higher volatility, or both. It may be worth reviewing the allocation. You can use the Portfolio Optimization tool to explore options for improving the Sharpe ratio.
