Treynor Ratio is a key performance metric for portfolio managers and traders. It highlights the effectiveness of a strategy in delivering excess returns relative to its exposure to overall market risk. Unlike other performance measures, it accounts for systematic risk rather than total risk, making it more relevant for diversified portfolios. Investors use this metric to compare funds or strategies that operate under different market conditions. A consistently high Treynor Ratio suggests a well-optimized strategy with strong returns per unit of risk.
