Consider four different stocks, all of which have a required return of $20$ percent and a most recent dividend of $$4\mathrm{.}30$ 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 $11$ percent growth rate thereafter. What is the dividend yield for each of these four stocks? What is the expected capital gains yield for each of these four stocks?
