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 uncorrelated (rAB = 0) .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 below 10% and a standard deviation (SD) of approximately 10%.
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 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%.
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 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%.

If investors are risk averse and hold only one stock, we can conclude that the required rate of return on a stock whose standard deviation is 0.21 will be greater than the required return on a stock whose standard deviation is 0.10.However, if stocks are held in portfolios, it is possible that the required return could be higher on the low standard deviation stock.
