Boulanger and Company hired you as a consultant to help estimate its cost of capital. You have obtained the following data: D0 = $0.75; P0 = $24.00; and g = 6.00% (constant). The CEO thinks, however, that the stock price is temporarily depressed, and that it will soon rise to $40.00. Based on the DCF approach, by how much would the cost of equity from retained earnings change if the stock price changes as the CEO expects? Show your calculations, if any, and explain your answer.
