To run this back-test rigorously I need to pin down a couple of practical details: 1. Market universe • Should we limit the search to U.S. listed equities (NYSE + NASDAQ), or do you have another universe in mind? 2. Re-ranking frequency & execution price • Do we form the “top-500 by volume” list each trading day at the close and buy them at the next day’s open (typical implementation), or buy at the same day’s close? • Positions are then liquidated 1 trading day later—at the next day’s close—correct? 3. Portfolio construction • Equal-weight each of the 500 names for one trading day (so the daily portfolio return is the simple average of the 500 one-day returns)? 4. Practical limit • My back-test engine currently evaluates one ticker at a time; to replicate a 500-stock basket I will compute the equal-weighted portfolio return series externally and feed it into the engine as a synthetic “ticker.” – This is fully supported, but please confirm you are comfortable with that approach. Let me know your preferences on the above, and I will proceed to fetch the data and run the back-test.
