The 1-Year Sharpe Ratio inidicates the risk-adjusted return of an investment over the past year. It is calculated as the annualized result of the average monthly excess return divided by its standard deviation over the past year. The monthly excess return is the monthly investment return minus the monthly risk-free rate (typically the 10-year Treasury Constant Maturity Rate).
