The period balance: money in, money out
In the Form 4 filings submitted between Sep 12, 2025 and Sep 1, 2026 there is not one open-market purchase of SLB N.V.: 22 sales worth $27.1M and zero dollars bought.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like SLB N.V.'s is the norm in the S&P 500, where much of the pay comes as stock. It is not a recommendation to buy or sell: it is what was filed.
Every transaction, code by code

| F | Tax withholding (shares surrendered for taxes) | 21 | $10.6M |
| M | Option exercise | 8 | $1.3M |

Who has traded
Over the 15 months of history, 15 distinct people or entities have filed SLB N.V. transactions: none bought on the open market and 8 sold. Counted by CIK, the fixed number the SEC gives each filer, and not by name, which each filer types their own way.
Of the 8 who sold on the open market (22 sales in all), the three biggest sellers account for $20.3M of the $27.1M: 75% of the money in three people.

How to read this data
9 of the 20 sales in the table are flagged as scheduled (10b5-1 plan): signed months ahead and executed automatically, so they say nothing about what the insider thinks today. SLB has no open-market purchase (code P) in the history, the most common case in the S&P 500: insiders are already paid in stock. The latest filing is from Sep 1, 2026, and a Form 4 arrives up to two business days after the trade.
14 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.

- Who really moves the market: the types of investorWho sits on the other side of each order, and where a company's own insiders fit among them.
- Supply, demand and price: why it rises and falls constantlyHow a piece of news ends up inside the price, and why the reaction to a filed sale is rarely the one you would expect.
