    Dear David, kindly see the below questions:

    consider two stocks, A and B. Assume their annual returns are jointly normaly distributed, the marginal distribution of each stock has mean 2% and standard deviation of 10%, an corrolation of 0.9. what is the expected return of stock A if the annual return of stock B is 3%.


    The answer is 2.9%.. however, shouldn't be 2.7%..(3%*.9)??

    It's a very simple question; however, i can't get 2.9%.
