Portfolio Return and Standard Deviation:
1. You are trading in a market that has only two securities available. Security A has an expected return of 8 percent and a standard deviation of 40 percent. Security B has an expected return of 20 percent and a standard deviation of 120 percent.
a) If you place half of your money in each stock, what is your expected return?
b) If you place 40 percent of your money in A and the remaining 60 percent in B, what is your expected return?
c) If the correlation between the returns of Securities a. and b. above is 0.8
what are the variance and the standard deviation of the returns of each of the two portfolios
you found in parts a. and 1 b. above?
2. You are trading in a market that has only two securities. Security C has an expected return of 6% and a standard deviation of 2.5% while security D has an expected return of 15% and a standard deviation of 8%. The correlation of returns between the two securities is -1.
a) If you place half of the money in each stock, then what is the expected return of
b) If you place 40% of the money in stock C and the remaining in stock D, then what is the expected return of the portfolio?
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 4 percent and the expected return on the market is 12 percent. Calculate the expected return on the security.
b) If the beta on the security in a) increases to 2, what is the new expected return? Why does the expected return increase as the beta increases?

b) If the September price of corn rises to $1.85, how much equity is in Zack's commodity account? Compute the profit/loss
