To clarify your request and ensure I design a back-test that genuinely answers your question: Scope of universe—do you want to include all U.S. common stocks (NYSE, NASDAQ, AMEX) when ranking daily trading volume, or a more limited universe (e.g., Russell 3000 constituents)? Weighting and execution assumptions—equal-weight each of the 500 names every day, trading at that day’s close and exiting at the next day’s close, or enter at the next day’s open and exit at the next day’s close? Transaction costs—should we incorporate estimates (e.g., 5 bps each side) or assume frictionless trading? Benchmark—would you like the results compared against any particular index (e.g., SPY) for context? Once I have these details, I can build the data-collection plan and run the back-test.
