Here Rt is the return on the stock and Rft is the risk-free rate for the same period. Rmt is the return on a stock market index (in this case the S&P 500 index). a; is the regression intercept, and B; is the slope (and the stock's estimated beta). Et represents the residuals for the regression. 19 20 21
