To build an accurate back-test for "buy the top 500 stocks by daily trading volume and hold them for one trading day," I first need to pin down a few details and confirm they match the capabilities of our back-testing engine: 1. Stock universe • Which market(s) should we draw the 500 names from? 2. Re-balancing mechanics • Do we select the top-volume list using today’s closing volume and then enter at next day’s open? 3. Weighting scheme • Equal-weight across the 500 names? 4. Practical limitations • Our current single-ticker back-testing engine cannot directly simulate a 500-stock portfolio in one call.
