The Sharpe Ratio is a fundamental metric in finance that evaluates the performance of investments by adjusting for risk. It measures the excess return per unit of risk, using the risk-free rate and the standard deviation of the investment's excess return. This ratio is crucial for comparing different investments or portfolios on a risk-adjusted basis. While useful, the Sharpe Ratio has limitations and should be used with other financial indicators for comprehensive analysis.
