To run this test rigorously I need to pin down two practical details that aren’t fully specified in the request: 1. Universe definition • “Top 500 stocks by daily trading volume” implies scanning the entire exchange list each day, ranking every ticker and re-forming a 500-stock basket. • With the tools currently available we can back-test a single-ticker strategy or an event impact series, but we don’t have a bulk-ranking interface that automatically handles hundreds of tickers per day. • Two workable alternatives are: a) Use a fixed universe such as the S&P 500 (or Russell 1000/3000) and each day pick the 500 names with the highest volume within that universe, or b) Simplify to a representative ETF (for example an equal-weight high-liquidity ETF) if the goal is just to gauge the general effectiveness of “high-volume names” rather than the precise daily 500-stock re-balance. 2. Trade-timing convention • The usual convention for this type of cross-sectional volume strategy is: – Identify the top-volume list at the close of day t, – Enter positions at the next day’s open, – Exit at that same day’s close (i.e., a 1-day holding period). • If you prefer buy-at-close / sell-next-close or another convention, just let me know. Could you confirm which universe approach (a or b) you’d like me to use, and whether the open-to-close convention is acceptable?
