Since there are three stocks in the portfolio, each weight will be 1/3. It does not matter whether compute the expected return by boom and bust first, or by stocks. The answer provided below is based on, first computing the expected return by stocks, and then by boom and bust. Expected return of portfolio with three stocks during boom =(310.18)+(310.04)+(310.31)=i Expected return of portfolio with three stocks during bust =(310.03)+(310.16)+(31(0.11))=i Final Expected Return of boom bust = Probability of boom Expected return of portfolio with three stocks during
