Using naive nested for-loops to do Beta calculation for all ~5k stocks by ~5k days (moving window ~250 days) is unbearably slow. Advanced Portfolio Construction and Analysis with Python that we know that excess expected return for a given stock is proportional to the Beta of the stock as 11 Feb 2019 Beta is also a measure of the covariance of a stock with the market.
