Assume the following: the investor's required rate of return is 15 percent, the expected level of earnings at the end of this year (Upper E1) is $5, the retention ratio is 50 percent, the return on equity (ROE) is 20 percent (that is, it can earn 20 percent on reinvested earnings), and similar shares of stock sell at multiples of 10.000 times earnings per share. Questions: a.Determine the expected growth rate for dividends. b.Determine the price earnings ratio (P/Upper E1). c.What is the stock price using the P/E ratio valuation method? d.What is the stock price using the dividend discount model? e.What would happen to the P/E ratio (P/Upper E1) and stock price if the firm could earn 25 percent on reinvested earnings (ROE)? f.What does this tell you about the relationship between the rate the firm can earn on reinvested earnings and P/E ratios?
