Discover the Treynor Ratio to learn how portfolios are evaluated using returns generated per unit of systematic risk.
The Treynor Ratio is a core risk-adjusted performance metric used in portfolio management to determine how effectively a portfolio or investment generates excess returns for every unit of systematic risk it carries. Developed by Jack Treynor, the ratio isolates market risk (beta) instead of total volatility, making it particularly relevant for evaluating well-diversified portfolios where unsystematic risk is assumed to be negligible.
Investors, fund managers, and analysts use the Treynor Ratio to compare mutual funds, portfolios, and investment strategies on a like-for-like, risk-adjusted basis. It helps answer an important question: Is an investment producing adequate returns for the market risk taken.
The Treynor Ratio measures the excess return an investment earns over the risk-free rate, relative to its beta (systematic risk). It captures how well a portfolio compensates investors for the risk inherent to market movements.
A higher Treynor Ratio indicates more efficient performance, showing greater returns per unit of market risk. Conversely, a negative or very low Treynor Ratio signals poor risk-adjusted performance.
Uses beta, not standard deviation
Suitable for diversified portfolios
Measures return per unit of systematic risk
Valuable for investment comparison across similar asset classes
Below is the Treynor Ratio formula in clean, plain-text format:
Treynor Ratio = (Portfolio Return – Risk-Free Rate) / Portfolio Beta
Where:
Portfolio Return = total return for the period
Risk-Free Rate = return on a risk-free asset (e.g., 3-month Treasury bill)
Portfolio Beta = sensitivity of the portfolio to market movements
The numerator measures excess return earned from taking market risk.
The denominator isolates that excess return relative to systematic risk only.
A higher output means improved risk-adjusted performance.
Follow these steps:
Calculate absolute or annualised return depending on the time frame.
Use a short-term government bond yield or the official risk-free benchmark of your market.
Beta is typically obtained from:
Portfolio analysis reports
Fact sheets
Market data platforms
Regression analysis vs. a market index
Treynor Ratio = (Portfolio Return – Risk-Free Rate) / Beta
Ensure beta is greater than zero. If beta ≈ 0, the Treynor Ratio becomes mathematically insignificant.
Assume the following:
Portfolio return = 14%
Risk-free rate = 4%
Portfolio beta = 1.2
Using the formula:
Treynor Ratio = (0.14 – 0.04) / 1.2
Treynor Ratio = 0.10 / 1.2
Treynor Ratio = 0.0833 or 8.33%
The portfolio generated 8.33% excess return for every 1 unit of systematic risk. If compared to another portfolio with a Treynor Ratio of 6%, this portfolio is more efficient on a risk-adjusted basis.
A Treynor Ratio calculator typically requires the following inputs:
Portfolio return (annualised or period return)
Risk-free rate
Portfolio beta
The calculator outputs the Treynor Ratio instantly. Many investment platforms and data services provide Treynor Ratio pre-computed for mutual funds and ETFs.
While the Treynor Ratio is powerful, it has several limitations:
Beta is not constant; it changes across market cycles. Incorrect beta estimations distort the Treynor Ratio.
The metric is suitable for:
Large portfolios
Index funds
Diversified mutual funds
If unsystematic risk is high, Treynor Ratio interpretation becomes flawed.
If beta is negative or close to zero, the ratio becomes meaningless.
A slight difference in the assumed risk-free rate can meaningfully alter the outcome.
Unlike the Sharpe Ratio, it ignores specific risk components that may affect real-world performance.
The Treynor Ratio is most effective in the following scenarios:
Suitable for comparing mutual funds or ETFs where unsystematic risk has been diversified away.
Works well for portfolios sensitive to broader market movements.
A common metric in performance evaluation frameworks.
Useful for multi-year performance studies where beta is more stable.
Index funds and passively managed portfolios often use Treynor Ratio as a benchmarking tool.
The Treynor Ratio helps evaluate performance relative to market risk. It focuses on systematic risk, making it particularly useful for diversified portfolios where stock-specific volatility is reduced. By combining simplicity with strong analytical value, it remains one of the widely used tools for evaluating performance in relation to risk.
Key points to remember:
The Treynor Ratio evaluates how effectively an investment earns returns relative to its exposure to market risk.
It uses beta, making it suitable for diversified portfolios where unsystematic risk is minimal.
A higher Treynor Ratio corresponds to improved risk-adjusted performance.
Despite its strengths, it has limitations—beta instability, sensitivity to the risk-free rate, and applicability only to diversified investments.
When used alongside the Sharpe Ratio and Jensen’s Alpha, the Treynor Ratio provides a comprehensive view of portfolio performance.

The Treynor Ratio is a risk-adjusted performance measure that shows the excess return earned for every unit of systematic risk taken, with systematic risk represented by beta.
The Treynor Ratio uses beta to evaluate performance against systematic market risk, making it suitable for well-diversified portfolios. The Sharpe Ratio uses standard deviation, capturing total risk, and can therefore be applied to any portfolio regardless of diversification.
The Treynor Ratio can be limited by unstable beta estimates, sensitivity to the chosen risk-free rate, and reduced relevance for portfolios that are not well diversified. It is also unreliable for assets or portfolios with negative beta values.
A Treynor Ratio of 0.5 indicates that the investment produced 0.5 units of excess return for every unit of systematic risk undertaken, showing the return generated relative to market-linked risk exposure.
The Treynor Ratio is also referred to as the reward-to-volatility measure when specifically applied to systematic risk represented by beta.
