Abstract

Early in the 1950s, academics and investors started proposing in earnest a variety of summary statistics to capture in a single number the quality of an investment. Sharpe Ratio became the most commonly used, and it's an important metric, but maximizing Sharpe Ratio doesn't always maximize risk-adjusted return. In cases with a leverage constraint, optimal risk-adjusted return depends on both Sharpe Ratio and level of return.
