Suppose a factor model is appropriate to describe the returns on a stock. The current expected return on the stock is 12.2 percent. Information about those factors is presented in the following chart:

a. What is the systematic risk of the stock return?

b. The firm announced that its market share had unexpectedly increased from 12 percent to 15 percent. Investors know from past experience that the stock return will increase by .75 percent for every 1 percent increase in its market share. What is the unsystematic risk of the stock?

c. What is the total return on this stock?
