D 1 = Expected dividend per share to be paid next year; k = Investor’s required rate of return g = Expected dividend growth rate There are basically two forms of the model: Stable model: As per the model, the dividends are assumed to grow at the same rate. ERi = Rf + βi (ERm −Rf) where: ERi = expected return of investment Rf = risk-free rate βi = beta of the investment (ERm −Rf ) = market risk premium 3. The Capital Asset Pricing Model (CAPM) describes the relationship between the expected return and risk on any asset or portfolio. In the graph above, we plotted excess stock returns over excess market returns to find the line of best fit.
