Let's start by looking at the Sharpe Ratio (SR), Sortino Ratio (SORT), and Adjusted Sharpe Ratio (A-SR) via annualized calculations. A brief summary of each:

Sharpe Ratio: a performance metric that adjusts returns based on volatility.

Sortino Ratio: similar to the Sharpe ratio except that this metric only penalizes volatility associated with negative returns whereas SR treats all volatility equally.

Adjusted Sharpe Ratio: a variation of the standard Sharpe ratio that adjusts for skewness and kurtosis by penalizing returns for negative skewness and excess kurtosis. The metric was outlined in Pezier and White (2006).

In all three cases, the risk-adjusted performance metrics currently rank as modestly above their respective median results relative to the historical record for the past 100-plus years. The current 10-year Sharpe ratio, for instance, is 0.46 vs. the median 0.38. The current Sortino ratio: 0.68 vs. the 0.60 median. The Adjusted Sharpe Ratio is currently 0.40 vs. a median of 0.38. Here are the historical results at the quartiles:

Sharpe Ratio Sortino Ratio Adjusted Sharpe Ratio
0% -0.37 -0.36 -0.32
25% 0.07 0.22 0.15
50% 0.38 0.60 0.38
75% 0.84 1.35 0.69
100% 1.70 3.81 1.56
