TREYNOR RATIO

Summary

The Treynor Ratio is a risk-adjusted performance measure that evaluates how much excess return an investment generates per unit of systematic risk (beta). It's calculated by dividing the difference between an investment's return and the risk-free rate by the investment's beta. Unlike the Sharpe ratio which uses total risk, the Treynor ratio focuses specifically on systematic risk that cannot be diversified away. A higher Treynor ratio indicates better risk-adjusted performance relative to market risk.

Usage Context

Critical when studying portfolio performance evaluation, comparing investments with different risk profiles, and understanding risk-adjusted returns in portfolio management and investment analysis courses.

Common Confusions

• Confusing Treynor ratio with Sharpe ratio - students often mix up when to use total risk vs. systematic risk
• Thinking higher beta always means worse Treynor ratio
• Not understanding that Treynor ratio is only meaningful for well-diversified portfolios
• Assuming negative Treynor ratios are always bad without considering market conditions
