Helping others understand things one step at a time
Using the CAPM formula we find the expected return on ABC:
r=5%+1(8%-5%)=8% (when beta=1 it is just the return of the market)
Now we treat the dividend as a perpetuity and price the stock as a growing perpetuity:
P=.8/(8%-4%)=$20
a) so ABC should sell for $20 today
now if the growth rate and beta increase we go back to the beginning and resolve for the return of the stock:
r=5%+1.5(8%-5%)=9.5%
P=.8/(9.5%-6%)=$22.86
b) so if the conditions are changed, ABC should sell for $22.86 today
