To run this back-test accurately I’ll need to pin down a few practical details: (1) Stock universe—U.S.-listed common stocks on NYSE + NASDAQ (default), or a different universe? (2) Rebalancing logic—Select the 500 names with the highest dollar trading volume each trading day, buy at that day’s close and sell at the next day’s close (1-day holding period, no overlap), equal-weighted. (3) Frictional costs—Assume zero transaction cost/slippage (default), or specify cost assumptions? (4) Benchmark—Compare the strategy to SPY, equal-weight index, or no benchmark? If the default assumptions above are acceptable, let me know and I’ll proceed with the data-pull and back-test. If you’d like to adjust any of the items, please specify.
