Consider four different stocks, all of which have a required return of 19% 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 -5% 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.
