Jean-Marc Gilson

Jean-Marc Gilson is a declared insider at 2 companies (chief executive); the most frequent names are Westlake Chemical Partners LP and Corteva, Inc. Between 22 August 2024 and 28 April 2026, the trades on record add up to 7 filings.

Every open-market trade on record is a purchase: 6 purchases worth €50k, and no sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 1 share grant.

A typical purchase (the median) is worth €7,641. Of 6 purchases, 4 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. Looking at 6 purchases old enough to measure, the stock rose over the following 90 days in 50% of cases; the median change was -5.8%. Past outcomes like these are no guarantee of what comes next.

The record was last updated on 30 April 2026 with a share grant in Corteva, Inc. The clock since the last published purchase (29 August 2025) now reads 421 days. The median gap between a trade and its publication by SEC (Form 4) is 4 days. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
