Joe wants to use a single index model to estimate the expected return and standard deviation of a portfolio. Assume that Joe's portfolio is comprised of three well-diversified protfolios (so that we can ignore the variance of the error terms). Further assume that a and B are the y-intercept and slope parameters of the single index model. Joe invests 20% in Portfolio A, with an a = .01 and B = 1.0, he invests 40% in Portfolio B with an a = .04 and B = 1.5 and he invests 40% in Portoflio C with an a = .03 and = 2.0. If the expected return on the Single Index is 10% and the standard deviation of the single index's returns is 20... what is the estimated expected return and the estimated standard deviation of returns on Joe's portfolio? O Expected return = 16.03% and Standard Deviation of returns = 32% O Expected return = 15.06% and Standard Deviation of returns = 6.71% O None of the answers listed here. O Expected return = 15.06% and Standard Deviation of returns = 30% Joe wants to use a single index model to estimate the expected return and standard deviation of a portfolio.
