To run this back-test rigorously we need to make a few practical choices that were not specified explicitly in your request. Please review the default assumptions below and let me know if you’d like anything changed before I pull the data and run the calculation: Market universe includes all common stocks listed on NYSE, NASDAQ, and AMEX. Re-balancing occurs daily by ranking the universe by trading volume, forming an equal-weighted basket of the top 500 names. Prices will be adjusted for splits and dividends, and transaction costs are assumed to be zero. The analysis spans from January 3, 2022, to September 10, 2025. Once confirmed, the process will involve retrieving volume and adjusted-close data, constructing the daily basket, and calculating cumulative returns, , and Sharpe ratios relative to the S&P 500 benchmark.
