What Is a Risk-Adjusted Return?

What Is a Risk-Adjusted Return?

Let me break this down for you: a risk-adjusted return is essentially a way to calculate the profit or potential profit from an investment while factoring in the level of risk you're taking on to get there. We measure that risk against something virtually risk-free, like U.S. Treasuries. Depending on the method, you might see this as a number or a rating. You can use it for individual stocks, investment funds, or even your entire portfolio.

How Risk-Adjusted Returns Improve Investment Analysis

Here's why this matters to you as an investor: the risk-adjusted return shows how much profit your investment generated compared to the risk it carried over a specific period. If two investments deliver the same return, the one with lower risk has the better risk-adjusted return. You can apply something like the MAR ratio to compare trading strategies, hedge funds, or advisors. Common risk measures include alpha, beta, R-squared, standard deviation, and the Sharpe ratio—stick to the same one for each investment to get a true apples-to-apples view. Just remember, different measures can yield different results, so know which one you're using.

Common Risk-Adjusted Return Calculation Methods

Let's get into the nuts and bolts of how you calculate these. Start with the Sharpe ratio: it measures the excess profit over the risk-free rate per unit of standard deviation. You take the investment's return, subtract the risk-free rate—often the 10-year Treasury bond yield—and divide by the standard deviation. Higher is better. For instance, if Mutual Fund A returned 12% with a 10% standard deviation and the risk-free rate was 3%, its Sharpe is 0.9. Mutual Fund B at 10% return and 7% deviation gets a 1, making it better risk-adjusted despite the lower raw return.

Then there's the Treynor ratio, similar but using beta in the denominator instead. Again, higher is better. Using the same funds with a beta of 0.75 each, Fund A gets 0.12 and Fund B 0.09—so here, Fund A wins on systematic risk.

Additional Metrics for Evaluating Investment Risk

Beyond those, you have other tools in your kit. Alpha looks at an investment's return relative to a benchmark. Beta compares it to the market overall—a beta over one means more fluctuation than the market, under one means less. Standard deviation tells you about return volatility around the average, with wider spreads indicating more variability. R-squared shows how much of the performance ties to an index. These each give you a unique angle on risk.

Important Considerations for Risk-Adjusted Returns

Don't get carried away avoiding risk entirely—it's not always smart in investing. If you're looking at short timelines, these numbers might mislead you. In bull markets, a lower-risk fund could underperform what you want, while a higher-risk one might beat its benchmark. Sure, volatile periods hit high-risk funds harder, but over full cycles, they often come out ahead. Balance it out.

Frequently Asked Questions

You might wonder about the four main risk-adjusted measures: they're the Sharpe ratio, alpha, beta, and standard deviation. Yes, the Sharpe is one way to gauge risk-adjusted return, but not the only. For real estate, you can adapt these if you have the data—like average return and standard deviation against the 10-year Treasury for a Sharpe calculation.

The Bottom Line

At the end of the day, these risk-adjusted metrics help you assess an investment's risk-reward setup against a benchmark like the 10-year Treasury. Tools like Sharpe and Treynor, plus alpha and beta, offer varied views. Use the same measure across investments for accurate comparisons, and remember, it's about whether the reward matches the risk you're comfortable with.
