To ensure I set up this back-test exactly the way you intend, could you please help me clarify a few key points? 1. Universe of stocks • Which market (e.g., U.S.-listed equities)? • Is the “top 500” re-selected every day based on the previous day’s trading volume, or on the same day’s volume (which would introduce look-ahead bias)? 2. Entry & exit prices • Do you want to buy at the day’s open and sell at that day’s close, or buy at today’s close and sell at tomorrow’s close/open? • If you have another convention in mind, please specify. 3. Weighting & transaction costs • Equal-weight each of the 500 names, or weight by dollar volume / market cap? • Should we include transaction costs (e.g., bid-ask spread, commissions) or slippage? 4. Data scope • Is “from 2022 to now” meant to start on 2022-01-01? • Do you want the test run up to today’s date (2025-09-22)? Once I have these details I can build the data-retrieval plan and run the back-test for you.
