To run this back-test I need to make two small points clear before we start retrieving data and calculating results: 1. Universe of tradable stocks • Do you want to consider all U.S.-listed common stocks (NYSE + NASDAQ + NYSE Arca), or limit the universe to a standard index such as the Russell 3000 or S&P 1500? • Using the full market is possible, but it greatly increases the data volume and processing time. 2. Execution convention • By default I will assume: – Buy the selected names at the same day’s close. – Hold them one full trading session. – Exit at the next day’s close. • Positions will be equal-weighted across the 500 names each day. If these assumptions are acceptable, please confirm the desired universe (e.g., “all U.S. equities” or “Russell 3000”). Once I have that, I can generate the data-retrieval plan and run the back-test.
