AI Holders Summary · Q2 2026

Schlumberger Limited (ticker SLB, CUSIP 806857108) is the world's largest oilfield services company, providing reservoir characterization, drilling, production, and digital solutions to upstream and midstream operators globally. Its revenue tracks drilling-activity levels, completion spending, and commodity prices, making SLB highly cyclical and sensitive to oil-and-gas cycle timing. In Q2 2026, only eight institutions reported SLB — a $2.96M aggregate representing one of the smallest holder sets in this batch — suggesting the name is not a favored institutional exposure at this moment. MassMutual Private Wealth & Trust, the largest holder at $1.68M and 36,151 shares, reduced its position by 9,222 shares — a 19.4% liquidation that reduced the reported base from 45,373 to 36,151 shares and produced a valueChange of -$651K, the largest negative value movement in the batch. The combination of a large absolute liquidation and a deeply negative valueChange indicates that SLB stock fell materially during the quarter and that MassMutual timed acceleration on the downside. Eastern Bank liquidated 752 shares (-$49K), Versant Capital cut 113 shares (-$35K), CX Institutional cut 424 shares (-$90, roughly flat in value unit terms), and Kozak Associates liquidated their last 2 shares ($-110). The only addition in the entire cohort came from Hilltop National Bank, which increased from 7,550 to 7,945 shares (+395, -$19K value loss). Silverleafe Capital held 10,000 shares flat. The contract on SLB within this cohort is uniformly bearish: eight holders, zero buyers, one new entrant, one small buyer.
