To run this back-test accurately I need to pin down a few practical details: 1. Stock universe • Do you want all U.S. exchange-listed common stocks (NYSE + NASDAQ), or a different market? 2. Rebalancing mechanics • Do we buy at the close of day t (after we know that day’s volumes) and sell at the close of day t + 1, or use opens instead? 3.
