Costco's $1.89 Billion Volume Slump Drags Stock to 42nd in U.S. Rankings Amid Supply Chain Strains and Market Consolidation

On October 2, 2025, Costco Wholesale (COST) closed with a 0.06% decline, trading on a volume of $1.89 billion, a 21.93% drop from the previous day’s activity. The stock ranked 42nd in trading volume among U.S. equities. While no immediate catalysts were cited in publicly available reports, the muted session suggests limited near-term momentum amid broader market consolidation.

Analysts highlighted that Costco’s performance remains tied to macroeconomic signals, including consumer spending trends and inflationary pressures. Recent earnings reports have shown resilience in membership growth and average basket sizes, but rising input costs continue to temper profit margins. Investors appear to be recalibrating expectations as the company navigates a mixed retail environment, balancing high demand for bulk purchases against supply chain uncertainties.

To run this back-test accurately I need to pin down a couple of practical details so the data pull and portfolio construction match your intent: 1. Universe • All U.S. common stocks (NYSE + NASDAQ + NYSE Arca) – or a narrower list such as the Russell 3000, S&P 500, etc.? 2. Volume definition • Number of shares traded (share volume) – or dollar volume (shares × close price)? 3. Execution prices • Enter at next-day open and exit at that day’s close (i.e., 1-day holding period, intraday)? • Or enter at close and exit at the next day’s close? 4. Weighting & rebalancing • Equal-weight the 500 names selected each day and fully rebalance daily? 5. Transaction costs / slippage • Ignore for now, or apply a commission + slippage assumption? Once those points are clear I can generate the daily trade list, create the signal file, and run the back-test from 2022-01-03 through today (2025-10-02).
