To run a clean, reproducible back-test I’ll need to pin down a few practical details about the universe and the ranking rule: 1. Stock universe • Are we looking at all U.S. common stocks (NYSE + NASDAQ + NYSE Arca), or a narrower list such as the S&P 1500 / Russell 3000 constituents? • ADRs and ETFs excluded? 2. “Daily trading volume” definition • Raw share count, or dollar volume (shares × close price)? • Do you want the ranking taken from the previous trading day (so the list is known before the open), or intra-day selection at the close? 3. Portfolio construction • Equal-weighting each of the 500 names, or weighting by volume / inverse volatility / etc.? • Rebalance every trading day (buy today’s top-500 at the close, hold one session, exit next day’s close)? 4. Transaction costs & slippage • Should we include a round-trip commission or an assumed bid-ask spread? • Any limits on position size vs. ADV? Once these points are confirmed I can generate the data-retrieval plan and run the back-test from 2022-01-03 through the latest trading day.
