Consider the following information on two stocks:

	P(State)	Stock A	Stock B
Boom	20%	30%	25%
Normal	30%	15%	-5%
Slow	40%	-5%	5%
Bust	10%	-12%	0%

Calculate the variance of stock A.

Calculate the standard deviation of stock B

Calculate the covariance(A,B).

Calculate the correlation(A,B).

Suppose you invest $60,000 into stock A, and $40,000 into stock B. Calculate the expected return of the portfolio.
