Treynor Ratio

Definition

The Treynor Ratio is a performance metric that measures the excess return earned per unit of risk, specifically systematic risk, in an investment portfolio. By focusing on systematic risk, which cannot be diversified away, this ratio helps investors evaluate the return generated by an investment relative to its market risk exposure, making it a valuable tool for assessing international portfolios and understanding the benefits and challenges of diversification.

1. The Treynor Ratio is calculated using the formula: $$\text{Treynor Ratio} = \frac{R_p - R_f}{\beta_p}$$ where $R_p$ is the portfolio return, $R_f$ is the risk-free rate, and $\beta_p$ is the portfolio beta.
2. This ratio is especially useful for comparing portfolios that have different levels of systematic risk, as it provides a standardized measure of performance.
3. A higher Treynor Ratio indicates that an investor is receiving more return for each unit of systematic risk taken, making it a key consideration for international investments.
4. When assessing international diversification, understanding the Treynor Ratio can help investors determine if they are adequately compensated for the risks associated with foreign markets.
5. The Treynor Ratio is commonly used by portfolio managers and financial analysts to gauge performance in relation to market movements, allowing them to make informed decisions about asset allocation.
