To construct the 1-day “top-volume 500” strategy precisely as specified, several practical parameters must be defined prior to executing the back-test:
1. Stock universe: • All U.S. listed common stocks (NYSE + NASDAQ + AMEX)? • Only large-cap names (e.g., S&P 1500)? • Another universe?
2. Trade timing convention: • Buy at today’s close → sell at tomorrow’s close, or • Buy at tomorrow’s open → sell at tomorrow’s close? (Either approach is common; please specify.)
3. Position sizing: • Equal weight across the 500 names each day (default)? • Value-weighted or volume-weighted?
4. Frictional costs: • Ignore commissions/slippage (default), or • Include a per-trade cost assumption? (If yes, please specify.)
Once these four parameters are established, the daily trade list can be generated, and the back-test can be run from January 3, 2022, (the first trading day of 2022) to the latest close.
