Suppose Janet 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.

Suppose Janet 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 Average Annual Standard Deviation of Portfolio Return (Risk) Stocks Return (Percent) Combination (Percent) (Percent) 2.50 25 3.50 50 4.50 10 75 5.50 15 100 6.50 20 relationship between the risk of Janet's portfolio and its average annual return There is a Suppose Janet 75% currently allocates of her portfolio to a diversified group of stocks and 25% of her portfolio to free bonds, that is, she chooses combination D. She wants to reduce the level of risk associated with her portfolio from a standard deviation of 15 to a standard deviation of 5. In order to do so, she must do which of the following? Check all that apply. Place the entirety of her portfolio in bonds O Sell some of her stocks and use the proceeds to purchase bonds O Sell some of her bonds and use the proceeds to purchase stocks O Accept a lower average annual rate of return 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 Janet modifies her portfolio to contain 50% diversified stocks and 50% risk-free government bonds; that is, she chooses combination C. The average annual return for this type of portfolio is 4.5%, 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
