Question

Suppose two securities A and B have a covariance COVAB = 20 and are combined to form a portfolio.  The expected returns and standard deviations of the two securities are as follows:

rA = 10%, QA = 3%, rB = 12%, QB = 4%

Finally, $30,000 is the total investment in the two securities and $21,000 is invested in security B. What is the expected portfolio return rP? What is the standard deviation of portfolio return Qp?
