I understand you’d like to evaluate a daily-rebalanced portfolio that, , buys the 500 stocks with the highest trading volume and holds them for exactly one day. Before I proceed, could you please clarify a couple of points so that I can set up the back-test correctly and select the right data-retrieval approach? 1. Market universe • Should I limit the universe to U.S. listed equities only, or do you want to include other markets as well? 2. Selection & execution timing • Do you want the ranking done on each day’s COMPLETE volume (i.e., you buy at that day’s close and exit at the next day’s close), or should the ranking be based on the PREVIOUS day’s volume (i.e., you buy at the next day’s open and exit at that day’s close)? • This choice affects whether the strategy is “look-ahead” compliant. 3. Practical constraint of the current tool-set • The built-in back-testing engine available here is designed for single-ticker strategies. • If you’d like a genuine cross-sectional portfolio back-test (500 stocks traded daily), I can still implement it, but I’ll need to handle the portfolio aggregation manually. That is feasible, but it will require loading daily price & volume data for a large universe and computing the portfolio P&L outside the single-ticker engine. • Alternatively, we can approximate by testing a representative ETF (e.g., SPY) or another benchmark if that fits your objective. Please let me know your preferences on the above so I can proceed with the most appropriate (and technically executable) method.
