To run this back-test rigorously I need to pin down a few practical details and be sure we model it the way you have in mind: 1. Universe • Should we draw the “top-500 by trading volume” from all U.S.–listed common stocks each day, or from another universe (e.g., only S&P 500 constituents)? 2. Trade timing & prices • Do you want to “buy” at the close of the ranking day and exit at the next day’s close (close-to-close return), or buy at the next day’s open and exit at that day’s close (overnight excluded)? • Equal-weight each of the 500 names? 3. Practical note on tooling • The built-in back-test engine exposed here operates on one ticker or one synthetic index at a time. For a cross-sectional strategy (500 stocks re-selected daily) we’ll have to aggregate returns across tickers before feeding them to the engine. • I can handle that aggregation, but it affects run-time and file sizes—please confirm you’re okay with a “full-universe” run or let me know if you prefer a smaller proxy (e.g., top-500 by volume within the S&P 1500). Let me know your preferences and I’ll set the test up immediately.
