The financial markets of

The financial markets of country X are not very developed: there are only two companies, A and B, which are traded. The expected rate of return on A is 8% and 14% on B; the standard deviations of their rates of return are 5% for A and 10% for B and the correlation coefficient between their returns is 0.1.a. Calculate the expected return and standard deviation of the following portfolios:portfolio Percentage in A Percentage in BP1 0 100P2 40 60P3 60 40P4 80 20P5 100 0b. Represent in a graph (with the standard deviation of the portfolio on the horizontal axis and the expected returns on the vertical axis) the points corresponding to the combinations of expected return-standard deviation for each of the above portfolios. Draw approximately theset of all feasible expected returns-standard deviations that can be obtained by investing in the two stocks A and B.c. Which of the above portfolios are ecient?
