- Determine the average return and the standard deviation of returns for each stock. Use sample statistics (e.g., STDEV.S function).
- Determine the correlation coefficient and the covariance between each pair of stocks. Use sample statistics (e.g., COVARIANCE.S function).
- 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.
- Use the Solver to determine the minimum standard deviation that could be obtained by combining all three stocks into a single portfolio.
