Southwest Airlines Shares Tumble 3.42% Amid Fuel Costs and Union Talks as Stock Ranks 360th in U.S. Equity Market Volume

Southwest Airlines (LUV) closed 3.42% lower on Sept. 25, with a trading volume of $320 million, ranking 360th in U.S. equity market activity. The decline came amid mixed operational updates and broader market volatility.

Recent reports highlighted rising fuel costs and ongoing negotiations with pilot unions over compensation terms, both of which could pressure near-term margins. Analysts noted that the airline’s load factor in July dipped slightly below 2024 averages, signaling potential challenges in maintaining passenger pricing power during peak travel periods.

Separately, Southwest’s decision to extend fleet retirement timelines for certain Boeing 737 models drew scrutiny from short-term investors. While the move aims to optimize asset utilization, it raised concerns about potential maintenance costs and capacity constraints during the 2025-2026 winter travel season.

To run a precise test of a “buy-the-top-500-by-volume, hold one day, rebalance daily” strategy we need to clarify a few practical details so the back-test can be assembled correctly: 1. Universe • Should we use all U.S. common stocks (e.g., Russell 3000 constituents), or a narrower list such as the S&P 1500, NYSE-listed names only, etc.? 2. Volume metric • Dollar volume (price × shares) or share volume? 3. Trade timing assumptions • Rank at today’s close, buy at tomorrow’s open and exit at tomorrow’s close (the most common one-day-hold convention)? • Or buy at today’s close and exit at tomorrow’s close? 4. Weighting & transaction costs • Equal-weight each of the 500 names? • Any commission/slippage assumption you’d like to include? 5. Data availability • Our current single-ticker back-test engine cannot directly hold 500 simultaneous tickers, so we would construct an equal-weight portfolio index behind the scenes and back-test that synthetic series. Are you comfortable with that approach? Let me know your preferences (or simply confirm you’re happy with the default choices below) and I can proceed with the data-gathering and back-test: Default proposal if you’d like me to move forward without further tweaks • Universe: U.S. common stocks – Russell 3000 membership as of each day • Ranking metric: daily dollar volume • Execution: rank on today’s close, enter at next-day open, exit at next-day close • Weighting: equal across the 500 names selected each day • Transaction costs: ignore (0 bp) for a first pass, report gross returns only Just let me know if that works or what you’d like changed, and I’ll start the automated run.
