Risk-adjusted returns help you better understand where your investments are thriving and where they're flailing, especially if they have vastly different risk profiles. This can help you make more balanced investments, with an amount of risk you can quantify.
How is risk-adjusted return measured?
There are actually many ways to measure risk-adjusted return, but these are three common methods:
- Sharpe Ratio. The Sharpe Ratio looks at the return per total unit of risk.
- Sortino Ratio. The Sortino Ratio only looks at downside risk potential.
- Treynor Ratio. The Treynor Ratio looks at returns per unit of systematic risk, otherwise known as market risk.
These allow you to look at risk in different ways, and to consider other things like the risk-return trade-off that should be taking place when you're investing in riskier assets. Put another way, if you don't get a bigger reward for taking bigger chances with your money, then what is the point of exposing yourself to the higher chance of loss? Since you can't buy everything, the risk you take has to be worth the payout.
