Doing this gives a monthly standard deviation (volatility) of 17.9% for Stock A and just 3.6% for Stock B. This confirms the optics in the chart.

The standard deviation for the portfolio is 20. Hedge Fund A thus has a Sharpe Ratio of 0.8: excess returns of 16%, divided by the standard deviation of 20.

The standard deviation formula for a population is σ = √ (Σ (xi - μ)² / N). In this formula,σ stands for standard deviation, and xi is each value in the population, μ is the mean of all ...
