8. Risk and return Suppose Poornima 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 A 0 0 B 25 2.50 5 50 10 3.50 4.50 D 75 15 E 100 5.50 20 If Poornima reduces her portfolio's exposure to risk by opting for a smaller share of stocks, he must also accept a lower average annual return. higher ree bonds; that is, she Suppose Poornima currently allocates 25% of her portfolio to a diversified group of stocks and 75% of her portfoli chooses combination B. She wants to increase the average annual return on her portfolio from 2.5% to 4.5%. In lower so, she must do which of the following? Check all that apply. Sell some of her bonds and use the proceeds to purchase stocks Accept more risk Sell some of her stocks and use the proceeds to purchase bonds Sell some of her stocks and place the proceeds in a savings account 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 Poornima modifies her portfolio to contain 75% diversified stocks and 25% risk-free government bonds; that is, she chooses combination D. The average annual return for this type of portfolio is 4.5%, but given the standard deviation of 15%, the returns will typically (about 95% of the time) vary from a gain of to a loss of
