Solution: We are given the individual asset return and along with that investment amount, therefore first we will find out the weights as follows, 1. To construct a portfolio frontier, we first assign values for E (R1), E (R2), stdev (R1), stdev (R2), and ρ (R1, R2). Step 1: Firstly, determine the weight of each asset in the overall portfolio, and it is calculated by dividing the asset value by the total value of the portfolio. This is because increasing volatility (i.e risk) for a negative Sharpe Ratio gives a higher ratio (in constrast to the general assumption that higher risk means a lower Sharpe Ratio). Basically, you are inputting the weight of a column times the sumproducts of the weights column and the covariance column. This is known as the Sharpe Optimal Portfolio.Sample investment returns for the three stocks are provided, but the spreadsheet can be easily adapted to other stocks and a larger investment space.
