Determine the intrinsic value of Wal-Mart (price P0) using the dividend discount Model (DDM). Assess the value based on two forms of the DDM: the constant growth version, an assessment based on three years of projected dividends and a projected future stock price. Clearly state any assumptions you make to calculate the intrinsic price, including an estimation of Wal-Mart investor required returns from the Capital Asset Pricing Model (CAPM).
