Chapter 8, Problem 11PS
Portfolio risk and return Mark Harrywitz proposes to invest in two shares, X and Y. He expects a return of 12% from X and 8% from Y. The standard deviation of returns is 8% for X and 5% for Y. The correlation coefficient between the returns is .2.
- a. Compute the expected return and standard deviation of the following portfolios:
- b. Sketch the set of portfolios composed of X and Y.
- c. Suppose that Mr. Harrywitz can also borrow or lend at an interest rate of 5%. Show on your sketch how this alters his opportunities. Given that he can borrow or lend, what proportions of the common stock portfolio should be invested in X and Y?

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?
You are attempting to evaluate two possible portfolios, which consist of the same five assets held in different proportions. You are particularly interested in using beta to compare the risks of the portfolios, so he has gathered the data shown in the following table.
Calculate the betas for portfolios X and Y.
Compare the risks of these portfolios to the market as well as to each other. Which portfolio is more risky?
Assume a Portfolio of two assets A and B whose standard deviations of their returns
are 8.6% and 10.8% respectively, while their correlation coefficient of returns is Pas=
- 0.61. You are given the right to do portfolio optimization without restrictions. What
proportions would you choose and why?

- Show detailed steps to solve the following question. Consider a portfolio comprised of three securities in the following proportions and with the indicated security beta. a.) What is the portfolios beta? b.) Wht is the portfolios expected return?arrow_forwardAn investor wishes to contruct a portfolio consisting of security 1 and security 2. the expected return on the two securities are E(R1) = 0.08 And E(R2) = 0.12 and the standard deviation 1 = 0.04 and Standard deviation 2 = 0.06. the correlation coefficient between thier returns is P1,2 = -0.5. Investor is free to choose the investment proportions W1 And W2 only to requirment that w1+w2=1 and both w1 and w2 are positive.There is no limit to the number of portfolios that meet thses requirements, since there is no limit to the number of proportions that sum to 1.

You expect that after you invest, four possible mutually exclusive scenarios will occur, with associated returns (in %) for each of the three assets as listed below. The probability of each scenario is given below (Attached image). Find the expected returns and standard deviations of Asset A, B & C. (HINT: the expected return is given by the probability-weighted sum of returns in each scenario. The expected standard deviation is given by the square root of the probability-weighted sum of squared deviations from the expected return.) Is there any reason to invest in Asset A given its low expected return and high standard deviation?arrow_forward
