Suppose we have assets A and B with the following distribution of returns: Probability Return for A Return for B .1 .01 -14 .2 .03 .00 .4 .05 .14 .2 .07 .30 .1 .09 .50 a. Compute the expected returns for assets A and B, r and rg. b. Compute the variances of A and B, o and o c. Compute the covariance of A and B, AB d. Use the formulas for portfolio returns and risk to write the expected portfolio return and standard deviation for an equally weighted portfolio of A and B, Tp and Op- e. Use the formula to find the portfolio weights, a" and 1-a" for the minimum variance portfolio of A and B. f. Find the portfolio return and standard deviation of the minimum variance portfolio. 3. Expected return and CAPM Suppose the risk-free rate is 4% and the market portfolio and stock j have the following return distributions: Probability Market return Return for j 1 -.15 -.30 3 .05 .00 4 .15 -20 .2 20 .50 a.
