Telefonica Deutschland Holding AG (HAM:O2D) 3-Year Sharpe Ratio Explanation
The 3-Year Sharpe Ratio inidicates the risk-adjusted return of an investment over the past three years. It is calculated as the annualized result of the average three-year monthly excess returns divided by its standard deviation in the three-year period. The monthly excess return is the monthly investment return minus the monthly risk-free rate (typically the 10-year Treasury Constant Maturity Rate). If the risk-free rate for a specific region is not available, U.S. data is used by default.
The greater a portfolio's Sharpe Ratio, the better its risk-adjusted performance. A negative Sharpe Ratio means the risk-free rate is greater than the portfolio’s historical or projected return, or else the portfolio's return is expected to be negative.
