To run this back-test accurately I need to clarify a few practical details and assumptions: 1. Stock universe • Should we use all U.S. common stocks listed on NYSE + NASDAQ + AMEX, or a different universe? 2. Ranking frequency and holding logic • The usual interpretation is: – Every trading day at the close we rank that day’s universe by trading volume. – Buy (equal-weight) the top-500 names at that same close. – Exit those positions at the next day’s close (i.e., a 1-day holding period). • Please confirm this “close-to-close” convention (or let me know if you prefer open-to-close or some other variant). 3. Weighting scheme • Equal-weighted across the 500 names (default), or volume-weighted / market-cap-weighted? 4. Cash & transaction assumptions • Ignore transaction costs and slippage (default), or should we include an estimate? Once I have these points confirmed I can generate the retrieval plan, pull the daily volume data, build the daily portfolios and run the strategy back-test from 2022-01-01 through today.
