It is estimated that stock A will return 10% if the economy is in normal condition next year, and the returns will be 16% and 3% respectively if the economy is in boom and bust conditions. The probability of the boom, normal, and bust economic conditions are estimated as 20%, 70%, and 10% respectively. What is the expected return of the stock is?
Q2. An investor plans create portfolio. One choice is to combine stocks A and B with 50% and 50% weight in each. If the return of A=20% and the return of B=16%, what will be the portfolio return? Another choice is to combine A with stock C. Stock C has the same return (16%) as B.
