To run this back-test rigorously I need to pin down a few practical details: 1. Stock universe • Should we use all primary-listed U.S. common shares (≈4,000 names), the Russell 3000, or another specific list? 2. Trade execution convention • Rank stocks by the prior day’s total dollar volume, then open positions at the next day’s open and close them at that day’s close (a 1-day holding period)? • Or rank and transact at the same day’s close, exiting at the next day’s close? 3. Slippage / transaction costs • Apply none (pure theoretical return) or include a per-trade cost? If the above defaults (U.S. common shares, buy next-day open, sell same-day close, zero costs) are acceptable, let me know and I’ll launch the data pull and back-test. Otherwise feel free to adjust any of the points.
