1. Consider the asset allocation with S&P500 and six securities of US companies; Hewlett- Packard (HP), Dell, Walmart (WMT), Target, British Petroleum (BP) and Royal Dutch Shell (SHELL). Risk premium of each asset and the variance-covariance matrix for seven assets can be found in Probl sheet in ps3_data.xls. (a) Find the risk premium, SD, Sharpe ratio and weight on each asset for the global minimum variance portfolio. (b) Find the risk premium, SD, Sharpe ratio and weight on each asset for the tangent portfolio. (C) Draw a graph of the efficient frontier (find the minimum SD when the risk premium is 0.04, 0.045, 0.05, 0.06, 0.07 and connect them along with the minimum-variance portfolio and tangent portfolio). 1.
