To run this back-test properly I need to pin down a few practical details that aren’t fully specified yet. Could you please confirm (or adjust) the following so I can set the test up correctly? 1. Market universe • Do you want U.S. listed common stocks only (NYSE + NASDAQ), or a different universe? 2. Ranking logic • “Top 500 by daily trading volume” – should the ranking be based on: a) share volume (shares traded), or b) dollar volume (shares × price)? • The ranking date = the same day we enter the trade, correct? 3. Trade mechanics • Entry price: day’s close or the next day’s open? • Exit price: next day’s close, or next day’s open? • Equal-weight the 500 names each day? 4. Transaction costs • Assume zero costs/slippage, or would you like to add a per-trade cost? 5. Benchmark (optional) • Any specific benchmark you’d like to compare the strategy against (e.g., S&P 500)? Once these points are clarified I’ll generate the data-gathering plan and run the back-test from 2022-01-01 to today.
