Assume a world that meets all assumptions of the portfolio theory. In this world we solely trade in securities A and B like depicted in the graph below. Short selling is allowed. xA and XB indicate the proportions of security A and B within a portfolio respectively. P1, P2, P3 and P4 represent portfolios that can be created by trading (either long and/or short) in securhies A and B. P3 is the portfolio with the lowest risk; the risk of P3 is 0%. The risk of security A and B is measured by the standard deviation of the returns in the particular security and equals 20% for both. The correlation coefficient of the returns between A and B is -1. 40% P1 E(R) A 30% P2 20% P3 10% P4 ++ 30% 0% 10% 20% 40% O(R) Question: Indicate which statements are correct. Take into account that everything is possible, from all correct to all wrong.
