10. Assume an economy in which there are three securities: Stock A with rA = 10% and A = 10%; Stock B with rB = 15% and B = 20%; and a riskless asset with rRF = 7%. Stocks A and B are perfectly negatively correlated (rAB = -1). Which of the following statements is most CORRECT?

a. The expected return on the investor's portfolio will probably have an expected return that is somewhat above 15% and a standard deviation (SD) of approximately 20%.

b. The expected return on the investor's portfolio will probably have an expected return that is somewhat below 15% and a standard deviation (SD) that is between 10% and 20%.

c. The expected return on the investor's portfolio will probably have an expected return that is somewhat below 10%

d. Since the two stocks have a zero correlation coefficient, the investor can form a riskless portfolio whose expected return is in the range of 10% to 15%.

e. The investor's risk/return indifference curve will be tangent to the CML at a point where the expected return is in the range of 7% to 10%.
