Schlumberger's Stock Slumps 0.14% as $650M Trading Volume Ranks 175th Amid Oilfield Turbulence

Schlumberger (SLB) closed down 0.14% on Sept. 18, 2025, with a trading volume of $650 million, ranking 175th in the U.S. equity market. The decline followed mixed signals from the oilfield services sector amid fluctuating energy prices and evolving project timelines.

Recent reports highlighted Schlumberger’s strategic focus on cost optimization and long-term contracts in key markets. Analysts noted that the company’s recent quarterly performance reflected disciplined capital allocation, though near-term earnings visibility remained constrained by global macroeconomic uncertainty. Operational updates emphasized progress in digital transformation initiatives and enhanced efficiency metrics across North American operations.

Market participants observed that Schlumberger’s stock price was influenced by broader industry dynamics, including client spending patterns and regulatory developments in major energy-producing regions. While the firm reaffirmed its commitment to shareholder returns through its dividend policy, investors remained cautious about short-term volatility linked to commodity price swings and geopolitical risks.

I can certainly set up a back-test for you, but I need to clarify two practical details before proceeding: 1. Universe & data source • Do you want to limit the universe to U.S.–listed common stocks, or a wider global universe? • Is an equal-weight portfolio of the 500 highest-volume names each day acceptable (the most common approach), or do you have a different weighting rule in mind? 2. Platform constraints Our built-in back-test engine currently takes one ticker (or an index) at a time, so to replicate a 500-stock basket we have two choices: • Pull the raw daily volume/price data for every U.S. stock and custom-code an equal-weight portfolio calculation (possible, but will involve several large data pulls and a few minutes of processing). • Use a liquid proxy (e.g., SPDR S&P 500 ETF – SPY) if your intent is roughly “large, liquid U.S. stocks” rather than literally the top-500-by-volume each day. Please let me know which route you prefer (or if you’d like an alternative), and I’ll kick off the appropriate data-retrieval and back-testing sequence right away.
