Problem 8-17 APT Consider a three-factor APT model. The factors and associated risk premiums are: Factor Change in gross national product (GNP) Change in energy prices Change in long-term interest rates Risk Premium (%) +5.5 0.5 +2.5 Calculate expected rates of return on the following stocks. The risk-free interest rate is 5.4%. a. A stock whose return is uncorrelated with all three factors. (Enter your answer as a percent rounded to 1 decimal place b. A stock with average exposure to each factor (le, with b = 1 for each). (Enter your answer as a percent rounded to 1 dec place.) c. A pure-play energy stock with high exposure to the energy factor (b=1.9) but zero exposure to the other two factors. (En answer as a percent rounded to 2 decimal places.) d. An aluminum company stock with average sensitivity to changes in interest rates and GNP, but negative exposure of b=- energy factor (The aluminum company is energy-intensive and suffers when energy prices rise) (Enter your answer as a rounded to 2 decimal places.)
