Amerityre  (OTCPK:AMTY) 10-Year Sharpe Ratio Explanation

The 10-Year Sharpe Ratio inidicates the risk-adjusted return of an investment over the past ten years. It is calculated as the annualized result of the average ten-year monthly excess returns divided by its standard deviation in the ten-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.
