(a) Calculate the expected return and standard deviation for the following portfolios: i. 100% in Z. ii. 75% in Z and 25% in Y. iii. 50% in Z and 50% in Y. iv. 25% in Z and 75% in Y. v. 0 % in Z and 100% in Y. vi. -25% in Z and 125% in Y. Feel free to use a spreadsheet for this calculation and just report the two values per portfolio. (b) Draw the mean-standard deviation frontier. (c) Mark the three regions in which the share in security Z is negative, between 0 and 1, and bigger than 1. Indicate the minimum variance portfolio and the efficient frontier.
