United Tumbles to 161st in Volume as UPS Rises 1.38% on Logistics Sector Shifts

On September 26, 2025, United recorded a trading volume of $0.57 billion, a 23.57% decline from the previous day’s activity, ranking it 161st in market volume among listed stocks. Meanwhile, United Parcel Service (UPS) rose 1.38% during the session.

Market participants noted shifting investor sentiment toward logistics and transportation sectors following recent regulatory updates. A revised Department of Transportation proposal to streamline cross-border freight operations sparked speculation about potential cost efficiencies for major shippers. While the document explicitly excluded specific stock performance details, analysts observed that the sector-wide optimism indirectly supported UPS’s relative strength compared to peers.

Technical indicators suggested mixed momentum for United. Short-term traders highlighted a narrowing volume differential as a cautionary sign, with the stock failing to maintain above its 20-day moving average. However, long-term holders pointed to stable order flow in the $45–$47 price corridor, indicating potential support levels ahead of quarterly earnings reports.

To run this back-test robustly we need to agree on a few practical details that the raw description doesn’t fully pin down: 1. Universe • “All U.S. listed shares” can be 6,000+ tickers, while the S&P 500 is only 500 tickers. • Please confirm whether you really want the entire U.S. equity universe (NYSE + NASDAQ + NYSE‐Arca etc.) screened every day, or a well-defined subset such as the constituents of the S&P 500 or Russell 3000. 2. Ranking frequency and signal timing • I assume we create the ranking after the market close on day t, buy the next day at the open, and liquidate at the next day’s close (1-day hold). • Let me know if you prefer a different timing convention (e.g. buy at today’s close and sell tomorrow’s close). 3. Data availability • The available data connectors let us pull daily price & volume for a finite list of tickers. • If you really need “top 500 by volume across the whole market each day,” we’ll first have to build and maintain a daily ticker list (thousands of symbols), which is heavy but doable if you’re okay with the longer runtime. • Otherwise we can restrict to a commonly followed universe (e.g. S&P 500) and still rank by each day’s volume within that set. 4. Risk controls (optional) • Stop-loss, take-profit, max holding days (beyond the fixed 1-day rule) or drawdown limits—if any—can be coded into the back-test engine. By default I’ll leave them off unless you specify them. 5. Benchmark & metric preferences • Typical outputs are cumulative return curve, annualized return, volatility, max drawdown, Sharpe ratio, and day-to-day equity series. Let me know if anything else is needed. Please let me know (1) which universe you’d like to use and (2) confirm the trade timing. Once that’s settled I’ll proceed straight to data retrieval and the back-test without any further questions.
