The risk-free rate of return, rRF, is 7 percent; the required rate of return on the market, rM, is 10 percent; and Proton Companys stock has a beta coefficient of 1.2.

a. If the dividend expected during the coming year, D1, is $2.5, and if g = a constant 6 percent, at what price should Protons stock sell?

b. Now, suppose the Federal Reserve Board increases the money supply, causing the risk-free rate to drop to 6 percent and rM to fall to 9 percent. What would happen to Protons price?

c. In addition to the change in part b, suppose investors risk aversion declines, and this, combined with the decline in rRF, causes rM to fall to 8 percent. Now, what is Protons price?

d. Now suppose Proton has a change in management. The new group institutes policies that increase the expected constant growth rate from 6 to 7 percent. Also, the new management smooths out fluctuations in sales and profits, causing beta to decline from 1.2 to 0.9. Assume that rRF and rM are equal to the values in part c. After all these changes, what is its new equilibrium price? (Note: D1 is now $2.55.)
