8. Risk and return Suppose Kyoko is choosing how to allocate her portfolio between two asset classes: risk-free government bonds and a risky group of diversified stocks. The following table shows the risk and return associated with different combinations of stocks and bonds. Fraction of Portfolio in Diversified Stocks (Percent) Average Annual Return (Percent) 1.50 Standard Deviation of Portfolio Return (Risk) (Percent) Combination 3.50 5.50 7.50 9.50 There is a relationship between the risk of Kyoko's portfolio and its average annual return. Suppose Kyoko currently allocates 25% of her portfolio to a diversified group of stocks and 75% of her portfolio to risk-free bonds; that is, she chooses combination B. She wants to increase the average annual return on her portfolio from 3.5% to 7.5%. In order to do so, she must do whi the following? Check all that apply. O Sell some of her stocks and place the proceeds in a savings account There is a relationship between the risk of Kyoko's portfolio and its average annual return. Suppose Kyoko currently allocates 25% of her portfolio to a diversified group of stocks and 75% of her portfolio to risk-free bonds; that is, she chooses combination B. She wants to increase the average annual return on her portfolio from 3.5% to 7.5%. In order to do so, she must do which the following? Check all that apply. O Sell some of her stocks and place the proceeds in a savings account Sell some of her bonds and use the proceeds to purchase stocks Sell some of her stocks and use the proceeds to purchase bonds O Accept more risk The table uses the standard deviation of the portfolio's return as a measure of risk. A normal random variable, such as a portfolio's return, stays within two standard deviations of its average approximately 95% of the time. Suppose Kyoko modifies her portfolio to contain 50% diversified stocks and 50% risk-free government bonds; that is, she chooses combination C. TI average annual return for this type of portfolio is 5.5%, but given the standard deviation of 10%, the returns will typically (about 95% of the time) vary from a gain of to a loss of
