    a. In order to find the expected return of the portfolio, we must first calculate the return of the portfolio in each of the possible states of the economy. The return of a portfolio is:

    Ret of portfolio = wa*Ra + wb*Rb + wc*Rc where wa, wb, wc,... are the weights of each of the components of the portfolio (in this case: wa = 0.28, wb = 0.44, wc = 0.28) and Ra, Rb, Rc are the returns of each component. So, for example, if the state is "Boom", the return would ...
