Sharpe Ratio
A metric measuring risk-adjusted return relative to the volatility of the investment.
Full Definition
The Sharpe ratio measures the excess return earned per unit of risk, calculated by subtracting the risk-free rate from the portfolio return and dividing by the standard deviation of returns. A higher Sharpe ratio indicates better risk-adjusted performance. Values above 1.0 are considered acceptable, above 2.0 is very good, and above 3.0 is excellent. It helps compare strategies with different risk profiles.
