A portfolio consists of 3 securities, 1, 2 and 3. The proportions of these securities are: w1 = 0.2, w2 = 0.4 and w3 = 0.4. The expected returns of these securities are 10%, 7%, and 11% respectively. The standard deviations of returns on these securities are: sl = 3%, s2 = 2%, and s3 = 4%. The correlation coefficients among security returns are r12 = 0.1, r13 = 0.2, r23 = 0.3. What is the expected return and standard deviation of portfolio return?
