    Virgin: ”What is the exact definition of this ratio?”

    The Sharpe ratio can be calculated as the amount of:

    Excess Returns divided by the Annualized SD of Account Returns (ER / ASDAR)


    ER = Annualized Account Return - Risk Free Return (AAR - RFR)

    RFR = A risk free investment such as a T-Bill

    There are more complex methods that may, for instance, alter the SD calculation or use projected returns.
