To run this back-test accurately we’ll need to download a fairly large data set (daily prices and volumes for the entire U.S. equity universe from 2022-01-03 through today, then re-rank the universe every day to pick the 500 most-active stocks). Before I launch the data retrieval and calculations, let me confirm a few assumptions and default settings so the test matches your intent: 1. Universe • All primary-listed U.S. common stocks and ETFs (tickers on NYSE, NASDAQ and NYSE-Arca), excluding OTC and preferred shares. 2. Ranking rule • At each day’s close, rank by that day’s raw trading volume (shares traded) and select the top 500 tickers. • Equal-weight the basket. 3. Trade execution & holding period • Buy at the same day’s official close (T) and sell at the next day’s official close (T+1), i.e. a 1-day holding period. • No transaction costs or slippage (unless you’d like me to include a cost assumption). 4. Corporate-action adjustments • Use fully adjusted close prices (split and dividend adjusted) so the return series is free of mechanical jumps. If these defaults look good, just let me know and I’ll run the data retrieval and back-test. If you’d like any tweaks—different universe, transaction costs, open-to-close instead of close-to-close, etc.—please tell me and I’ll adjust before proceeding.
