FAQ

Why is Sharpe ratio used?

The Sharpe ratio is used by investors and analysts to compare the performance of different investments or portfolios on a risk-adjusted basis. It helps to determine whether an investment or portfolio is generating adequate returns relative to the amount of risk it is taking on.

What is the good Sharpe ratio?

Here is a table that provides a general guideline for interpreting Sharpe ratios:

 

Sharpe Ratio Interpretation
< 1 Poor risk-adjusted return
1-1.99 Good risk-adjusted return
2-2.99 Very good risk-adjusted return
3 or higher Excellent risk-adjusted return

 

It is important to note that these are just general guidelines, and what is considered a good Sharpe ratio may vary depending on the industry, investment strategy, and risk appetite of the investor.

How is Sharpe ratio calculated?

The Sharpe ratio is a financial metric used to evaluate the performance of an investment or portfolio in relation to its risk. It is calculated as the excess return of the investment or portfolio above the risk-free rate divided by the standard deviation of those excess returns.

 

The formula for the Sharpe ratio is as follows:

Sharpe Ratio = (Rp - Rf) / σp

 

where:

  • Rp = the expected return of the investment or portfolio
  • Rf = the risk-free rate of return
  • σp = the standard deviation of the investment or portfolio's excess returns
