To evaluate a daily-rebalanced portfolio of the top 500 volume stocks, key prerequisites include a comprehensive volume ranking dataset from January 1, 2022, to the present, a defined trade execution rule (e.g., close-to-close or open-to-close), and a methodology for accounting for transaction costs and slippage.
