Consider four different stocks, all of which have a required return of 13 percent and a most recent dividend of $3.75 per share. stocks w, x, and y are expected to maintain constant growth rates in dividends for the foreseeable future of 10 percent, 0 percent, and −5 percent per year, respectively. stock z is a growth stock that will increase its dividend by 20 percent for the next two years and then maintain a constant 5 percent growth rate thereafter. a. what is the dividend yield for each of these four stocks? (do not round intermediate calculations and enter your answers as a percent rounded to 1 decimal place, e. g., 32.1.) b. what is the expected capital gains yield for each of these four stocks? (leave no cells blank - be certain to enter "0" wherever required. a negative answer should be indicated by a minus sign. do not round intermediate calculations and enter your answers as a percent rounded to 1 decimal place, e. g., 32.1.)
