GStock calculates a net accumulated Return (R) based on the following formula:

Rn = Y1 * Y2 * Y3... * Yn – 100%

Where:

• Y – The net Yield of a single trade within an investment strategy as calculated by GStock. Y1 is the Yield achieved in the first trade; Y2 is the Yield achieved in the second trade; Yn is the Yield achieved in the last trade of an investment strategy.
• -100% – Since the Yield of every trade was calculated from the base (100%), when calculating the accumulated Return one must reduce the base (100%) from the result in order to get the correct net accumulated Return achieved.
