What is a good Sharpe ratio value?

A Sharpe ratio above 1 is generally considered acceptable, above 2 is very good, and above 3 is excellent. The ratio measures excess return per unit of risk, so higher values indicate better risk-adjusted performance.

Can I use the Sharpe ratio for any investment?

The Sharpe ratio works best for investments with positive expected returns and measurable volatility. It may be less meaningful for assets with very low returns or irregular cash flows where standard deviation is not a reliable risk measure.

Does a higher Sharpe ratio always mean a better investment?

Not necessarily. A very high Sharpe ratio can sometimes result from low volatility combined with modest returns, or from return data that includes outliers. It should be used alongside other metrics and qualitative assessment.

What is the risk-free rate in the Sharpe ratio formula?

The risk-free rate is the return of a theoretically risk-free asset, typically government bonds. It represents the minimum return an investor expects for taking on any risk, and the Sharpe ratio subtracts it to show excess return per unit of deviation.

How often should I recalculate my Sharpe ratio?

For actively managed portfolios, quarterly or monthly recalculations help track performance trends. For buy-and-hold investments, an annual review is usually sufficient unless you are regularly adding or withdrawing capital.
