Volume expansion suggests heightened short-term interest in the security, potentially driven by strategic investor positioning or market structure shifts. The elevated trading activity contrasts with broader market trends, indicating idiosyncratic catalysts rather than macroeconomic factors influencing the stock's performance.

For a rigorous back-test, several parameters require clarification: Should the universe include all U.S.-listed common stocks across NYSE, NASDAQ, and AMEX? Will entry/exit prices follow a "buy at today's close, sell at tomorrow's close" convention? How should weighting and capital allocation be structured—equal-weight across 500 names daily? Lastly, should transaction costs and slippage be factored in, , or excluded entirely?

Once these parameters are defined, the process can generate daily lists of top-500-by-volume stocks, calculate one-day forward returns, and aggregate results into a portfolio return series from January 3, 2022, to the present. Confirming these details will enable precise execution of the back-test framework.
