c) What is the portfolio standard deviation in b above?

SML and Required Rate of Return:

3. a) A security has a beta of 1.5 when the risk-free rate is 2.6 percent and the expected return on the market is 12 percent. Calculate the expected return on the security.

7. The S&P index is currently is at 1,990. You manage a $5 million indexed equity portfolio (Therefore, the beta of this portfolio is 1, same as the Market) The S&P 500 futures contract has a multiplier of 250.

a) If you are bearish on the stock market, how many contracts should you sell at 1,990 to fully eliminate your risk over the next 6 months?

Portfolio Return Standard Deviation Beta

1 9% 5% 1.50

2 13% 7% 2.10

3 22% 16% 1.75

Market 12% 10% 1.00
