What is a variance covariance matrix?
Briefly, the variance for a variable is a measure of the dispersion or spread of scores. Covariance indicates how two variables vary together. The variance-covariance matrix is a compact way to present data for your variables. The variance is presented on the diagonal (where the column and row intersect for the same variable), while the covariances reside above or below the diagonal.

How do you Calculate Stock Beta in Excel?
You need to use the variance and covariance functions in Excel 1. Calculate the covariance of the stock returns with respect to an index 2. Calculate the variance of the index 3. Divide the first number by the second. See the related link for a spreadsheet
