To run this back-test rigorously I need to pin down a few practical details and be sure the design fits within the capabilities of our current back-testing engine (which is geared to single-ticker or pre-defined basket symbols). Universe definition • Are we looking at all U.S. listed common stocks, only the S&P 500 constituents, or another universe? • If you already have (or can accept) a pre-defined basket symbol for “U.S. Top-500-by-Volume,” we can treat that as a single ticker; otherwise we would have to simulate a 500-stock daily-rebalanced portfolio, which our current engine does not directly support. Weighting & transaction details • Equal-weight each of the 500 names every day? • Ignore commissions/slippage, or apply some assumptions? Data frequency • Use daily close-to-close returns (rebalance at today’s close, hold until tomorrow’s close)? If you can confirm (or adjust) the above, I can proceed to: • Gather the daily volume rankings for the chosen universe from 2022-01-01 onward. • Generate the one-day-holding signals. • Run the back-test and present the return/risk metrics. Please let me know how you’d like to handle the universe and weighting so I can move on to data retrieval.
