  1. Determine the average return and the standard deviation of returns for each stock. Use sample statistics (e.g., STDEV.S function).
  2. Determine the correlation coefficient and the covariance between each pair of stocks. Use sample statistics (e.g., COVARIANCE.S function).
  3. 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.
  4. Use the Solver to determine the minimum standard deviation that could be obtained by combining all three stocks into a single portfolio.
