The annual returns of three stocks for the past seven years are given in the following table: Year Stock X Stock Y Stock Z 2011 3.00% 14.00% 19.00% 2012 9.00% 7.00% 11.00% 2013 12.00% 19.00% 5.00% 2014 19.00% 13.00% 12.00% 2015 23.00% -7.00% 11.00% 2016 5.00% -3.00% 7.00% 2017 10.00% 9.00% 14.00%
a) Determine the average return and the standard deviation of returns for each stock. Which stock has the highest expected return and which one has the highest risk?
b) Determine the correlation coefficient and the covariance between each pair of stocks.
c) Determine the average return and the standard deviation of returns of equally weighted portfolios consisting of two stocks (XY, YZ, and XZ) and three (XYZ) stocks. How do the returns and standard deviations of the portfolios compare to those of the individual stocks?
d) Create a chart that shows how the standard deviation of the two-stock portfolios changes as the weight of one of the stocks changes.
PLEASE ANSWER C,D AND PROBLEM E IN EXCEL!!
e) Use the Solver to determine the minimum standard deviation that could be obtained by combining each pair of two stocks, and also all three stocks into a single portfolio.
