EOG Resources' Trading Volume Plunges 67% to $260M Slipping to 422nd in U.S. Market

On September 22, 2025, , . This placed the stock at the 422nd position in terms of trading volume across the U.S. equity market. .

The drop in EOG’s volume and price occurred amid limited publicly available news directly tied to the company’s operations or strategic announcements. While broader energy sector dynamics often influence EOG’s performance, no specific catalysts were identified in the provided materials to explain the intraday move. The reduced liquidity suggests diminished short-term trading interest, potentially reflecting positioning adjustments or sector-wide risk-off sentiment.

To conduct this test rigorously, we would have to: (1) pull the entire U.S. stock universe each trading day; (2) sort it by that day’s dollar volume and select the top-500 tickers; (3) form an equal-weighted basket of those 500 names, buy at the close (or open) of that day, and liquidate at the next day’s close (one-day holding period); (4) roll the process forward from 2022-01-03 to today and aggregate performance. Unfortunately, the back-testing engine I’m allowed to run here only supports single-ticker or single-event analyses—not a rolling, multi-asset portfolio rebalanced daily. I can still give you something close if you’re willing to adjust the request. A few possibilities: Use a representative benchmark (e.g., SPY or Russell 1000) instead—simpler but not the same strategy; narrow the study to one ticker or ETF that roughly captures high-volume stocks; provide a fixed list of tickers (rather than re-ranking daily) so the engine can treat it as a single basket. Let me know which direction you’d like to take, or if you’d like me to suggest another workaround.
