Questions: a. Determine the expected growth rate for dividends. b. Determine the price earnings ratio (P/E). 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/E) and stock price if the firm could earn 24 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?
