Plot every stock on a graph with beta on the X-axis and expected return on the Y-axis. CAPM says they should all line up on a single straight line - the Security Market Line. Stocks above the line earn more than CAPM expects (positive alpha → maybe undervalued). Stocks below earn less (negative alpha → maybe overvalued). It's CAPM made visual.
