To run this back-test rigorously I need a few additional details and (given the toolset we have available) we may also want to agree on some practical simplifications. Please let me know your preferences on the following: 1. Universe definition • Do you want "all U.S. listed common stocks" (several thousands) or a specific subset (e.g., S&P 1500, Russell 3000, etcETC--.) from which the daily top-500-by-volume list will be drawn? • If you already have a ticker list you’d like me to use, feel free to provide it. 2. Trade timing convention • The classic implementation is: rank today at the close, buy the selected names at today’s close, and liquidate them at tomorrow’s close (close-to-close return). Is that acceptable, or would you prefer a different entry/exit convention (open-to-open, close-to-open, etc.)? 3. Weighting scheme • Equal-weighted across the 500 names (default) or volume-weighted / market-cap-weighted? 4. Transaction costs & slippage • Should we ignore these for now (default), or apply a particular percent cost each side? Once we nail down the above I can generate the data-retrieval plan and run the back-test.
