Walmart Gains Ground as $1.38 Billion Volume Ranks 60th in U.S. Equity Trading

On September 25, 2025, Walmart (WMT) closed with a 0.31% gain, trading with a volume of $1.38 billion, ranking it 60th in terms of trading activity across the U.S. equity market. The stock's performance coincided with broader retail sector dynamics and investor sentiment toward value-oriented plays amid shifting economic conditions.

Recent developments highlighted Walmart's strategic focus on e-commerce expansion and cost-cutting measures, which have positioned the retailer to capitalize on evolving consumer spending patterns. Analysts noted that the company's ability to balance inventory management with competitive pricing remains a key driver of investor confidence. However, macroeconomic uncertainties, including inflationary pressures and potential interest rate adjustments, continue to influence short-term trading behavior in the sector.

To run this back-test accurately we’ll need to pin down a few implementation details: (1) Universe—Should we use all actively traded U.S. common stocks (≈ 5,000 names) or another universe? (2) Volume definition—Rank by number of shares traded or by notional (shares × close-price)? (3) Trade timing—Signal is generated on day T (after the market closes). Do we enter positions at the next day’s open or at the same day’s close? (4) Portfolio construction—Equal-weight across the 500 names each day? Any position-level constraints (e.g., max weight, min price)? (5) Transaction costs & slippage—Should we apply any fixed commission or impact assumption? Once those points are clear I can generate the data-retrieval plan and launch the automated back-test for the period 2022-01-03 to today.
