Walmart Stock Rises 2.23% on $1.63B Volume, Ranks 46th in US Trading Activity

On September 11, 2025, Walmart Inc. (WMT) rose 2.23% with a trading volume of $1.63 billion, ranking 46th among U.S. stocks by volume. The retail giant's performance followed a mixed earnings report highlighting margin pressures but reaffirming fiscal 2025 guidance. Analysts noted that the stock's resilience stemmed from strong holiday sales forecasts and ongoing cost-cutting initiatives, though supply chain challenges remain a near-term concern.

Recent developments include Walmart's announcement of a $1 billion investment in U.S. distribution centers to bolster e-commerce capabilities. The move aims to reduce delivery times and inventory costs, with executives emphasizing improved last-mile logistics as a key differentiator against Amazon. Additionally, the company expanded its private-label partnerships with regional suppliers, signaling a strategic pivot to localize product offerings amid rising consumer price sensitivity.

Short sellers reduced exposure to WMT following the rally, with open interest dropping 12% week-over-week. Options data showed increased call buying at the 145-strike level, reflecting renewed bullish sentiment. However, some investors remain cautious, citing underperformance in international markets and regulatory scrutiny over labor practices in select markets.

I can certainly help you evaluate that trading-volume strategy, but to run the back-test I need to nail down a few practical details first: 1. Universe • Which market do you want the 500 names drawn from (e.g., all U.S.-listed common stocks, S&P 1500 constituents, NYSE + NASDAQ, etc.)? • Should we exclude ETFs, preferreds, ADRs, or other non-common-stock listings? 2. Execution price assumptions • Do we open the position at the same day’s close and exit at the next day’s close (close-to-close), or use next day’s open as the exit price? • Any transaction-cost or slippage assumption to apply? 3. Re-balancing mechanics • Equal-weight each of the 500 stocks, or weight by something else (e.g., volume share)? 4. Benchmark / risk-free rate • Do you want the results compared with a specific benchmark (e.g., SPY) and/or excess returns after a risk-free rate? Once we have these points clarified I’ll construct the data-retrieval plan, pull the daily volumes, build the rolling top-500 list, and run the day-ahead portfolio back-test for the 2022-01-03 → present period.
