An investiment portfolio consists of two securities, X and Y. The weight of X is 30%. Asset X's expected return is 15% and the standard deviation is 28%. Asset Y's expected return is 23% and the standard deviation is 33%. Assume the correlation coefficient between X and Y is 0.37. A. Calcualte the expected return of the portfolio. B. Calculate the standard deviation of the portfolio return. C. Suppose now the investor decides to add some risk free assets into this portfolio. The new weights of X, Y and risk free assets are 0.21, 0.49 and 0.30. What is the standard deviation of the new portfolio?

9. A portfolio is composed of two stocks, Stock A and B. The standard deviation of return for Stock A is 50% and for Stock B it is 40%. If the covariance between the returns for Stock A and Stock B is -0.04, compute the correlation coefficient between the returns for Stock A and Stock B.

Question: A portfolio consists of two stocks: Stock Expected Return Standard Deviation Weight Stock 1 10% 15% 0.30 Stock 2 13% 20% ??? The correlation between the two stocks’ return is 0.50(a) Calculate the expected return and standard deviation of the portfolio. Expected Return:   Standard Deviation: b) (i) Briefly explain, in general, when there would be “benefits of diversification” (for any portfolio of two securities).   (ii) Describe whether the above portfolio would exhibit “benefits of diversification” (and why). [No calculations are required.]     (c) Show your calculations re: whether the above portfolio exhibits “benefits of diversification”and indicate whether it does/doesn’t (and why).
