To set up this back-test robustly, I need to pin down a few practical details that weren’t specified: Universe—Should we limit ourselves to U.S. listed common stocks (NYSE + NASDAQ, no ETFs/ADR/penny stocks), or do you have another universe in mind? Rebalancing mechanics—Day-t ranking: use that day’s total traded dollar volume or share volume? Trade price: open at the close of the ranking day and exit at the next day’s close (standard implementation), or some other combination (e.g., next-day open / same-day close)? Weighting—Equal-weight across the 500 names, or volume-weighted / market-cap-weighted? Friction—Ignore transaction costs and slippage, or apply an estimate (e.g., 5 bps per round-trip)? I can assume standard defaults (U.S. common stocks, equal weight, trade at close → close, no frictions) and proceed automatically; or we can refine any of these choices first. Let me know which you prefer so I can start pulling the data and running the test.
