pt.alpha {YRmisc} | R Documentation |
Alpha is the intercept of a fitted line when dependent variable is the benchmark return and independent variable is a asset return of the same period. It is a measure of the active return on an investment. Alpha, along with beta, is one of the two key coefficients in the CAPM used modern portfolio theory.
