The Jensen's Alpha study calculates the average return of a security or portfolio relative to that of a benchmark index. In mathematical sense, it is equal to average rate of change in security's price minus that of the benchmark index multiplied by its Beta. Jensen's Alpha assumes that the security has a Beta of 1.0.

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