Future value FVn=(1+q)n , where n - year, q - grow rate for 1-8 years
Present value PVn=1/(1+r)n , r - required return
D0∗FV=Dn∗PV , D - dividend
Dn=D0∗FVn
Discounted income =Dn∗PVn
Pshare (after year 8) = D0*(1+q9)/(r - q9), where q9 is grow rate after year 8.
Pcorrected = Pshare*PV8 + Total DI, it is the price of the stock today.
