Problem 6-05 Given: E(R1) = 0.13 E(R2) = 0.19 E(01) = 0.03 E(02) = 0.05 Calculate the expected returns and expected standard deviations of a two-stock portfolio in which Stock 1 has a weight of 60 percent under the conditions given below. Do not round intermediate calculations. Round your answers for the expected returns of a two-stock portfolio to three decimal places and answers for expected standard deviations of a two-stock portfolio to four decimal places. a. 1.2 = 1.00 Expected return of a two-stock portfolio: Expected standard deviation of a two-stock portfolio: b. 11,2 = 0.60 Expected return of a two-stock portfolio: Expected standard deviation of a two-stock portfolio: c. P1,2 = 0.25 Expected return of a two-stock portfolio: Expected standard deviation of a two-stock portfolio: 1.2 = 0.00 d. Expected return of a two-stock portfolio: Expected standard deviation of a two-stock portfolio: e. 11,2 = -0.25
