Consider four different stocks, all of which have a required return of 17% and a most recent dividend of $4.50 per share. Stocks W, X, and Y are expected to maintain constant growth rates in dividends for the foreseeable future of 10%, 0%, and 25% per year, respectively. Stock Z is a growth stock that will increase its dividend by 20% for the next two years and then maintain a constant 12% growth rate thereafter.

a.) For all four stocks, what is the dividend yield and the expected capital gains yield?

b.) Identify the relationship between the various returns, in terms of growth and income, that you find for each of these stocks.
