To run this back-test robustly I need a few more details: 1. Market universe • Do we restrict the “top-500” ranking to a particular exchange (e.g., all NYSE + NASDAQ common stocks), or the whole US listed universe? 2. Re-balancing and execution prices • When you say “buy the top 500 stocks by daily trading volume, hold 1 day”, do you want to a) rank by the current day’s volume, buy at that day’s close, then sell at the next day’s close, or b) rank by the current day’s volume, buy at next day’s open, sell at next day’s close/open? 3. Transaction costs & slippage • Should we include any commission or slippage assumptions? 4. Benchmark / performance metric preferences • Any specific benchmark for excess return, or is total return sufficient? Once I have these points I can generate the data-retrieval plan and run the back-test.
