Adtran Networks SE (OTCPK:ADVOF) 3-Year Sortino Ratio Explanation
The 3-Year Sortino Ratio inidicates the risk-adjusted return of an investment over the past three year. It is calculated as the annualized result of the average three-year monthly excess returns divided by the standard deviation of negative returns 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.
