Answer: e. 10.65%.
Step-by-step explanation:
First find the expected return of the individual stocks;
Stock A = (0.2 * - 0.182) + (0.51 * 0.108) + (0.29 * 0.28) = 9.99%
Stock B = (0.2 * - 0.036) + (0.51 * 0.082) + (0.29 * 0.155) = 7.96%
Stock C = (0.2 * - 0.225) + (0.51 * 0.168) + (0.29 * 0.314) = 13.17%
Expected return of portfolio = ∑(Stock expected return * weight)
= (0.4 * 0.0999) + (0.3 * 0.0796) + (0.3 * 0.1317)
= 10.65%
Question is missing detail. Stock B return in recession is negative figure.
