To run this back-test accurately, I need to confirm a few details about the investment universe and implementation rules so the data pull and portfolio construction match what you have in mind: 1. Universe • Do you want the ranking done across all U.S. listed common stocks, or only within a specific index (e.g., S&P 500 constituents)? 2. Weighting & re-balance • Should the 500 selected names be held equal-weighted for the one-day holding period, or weighted by something else (e.g., market-cap)? 3. Price used for fills • Buy at next-day open and exit at same-day close (open-to-close return), or both at close (close-to-close return)? 4. Risk controls • Any stop-loss / take-profit / max holding-days rules beyond the mandatory one-day exit? (Default would be none.) Once I have these points, I can build the retrieval plan, pull the volume data, generate the daily portfolios, and run the back-test from 2022-01-03 to today.
