As opposed to Jensen's Alpha, the Alpha2 study calculates the excess average return of a benchmark index relative to the average return of a security or portfolio. Thus, it is equal to average rate of change in benchmark index price minus that of the security multiplied by benchmark Beta2. Alpha2 assumes that the security has a Beta2 of 1.0.

By default, this study conducts calculation against the SPX index.
