To perform this back-test in a statistically sound way I need to pin down a couple of practical details: 1. Universe. • Do you want all U.S.–listed common stocks (NYSE + NASDAQ + NYSE-Arca) or a specific subset (e.g., S&P 1500, Russell 3000, etc.)? • Should we exclude ADRs, ETFs, preferred shares, and other non-common securities? 2. Price used for entry/exit. • Enter at today’s close and exit at tomorrow’s close (close-to-close)? • Or enter at tomorrow’s open and exit at tomorrow’s close (close-to-open-to-close)? 3. Transaction costs. • Assume zero cost, or would you like to bake in an estimated commission/slippage per trade? 4. Rebalancing method. • Equal-weight the 500 names each day (most common), or weight by volume / market-cap? 5. Benchmark (optional). • Should I compare the strategy to a benchmark index such as SPY? Once you confirm these points I can pull the appropriate data, build the daily buy lists, and run the back-test from 2022-01-03 (first trading day of 2022) through today.
