Market trades split into 75 purchases (€1.3M) and 12 sales (€374k). On balance, insiders were net buyers of €890k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 13 share grants and 36 option exercises.

In size, the median ticket on the buying side is €8,478. 4 out of 6 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. For 3 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 0% of cases, with a median move of -8.5%. Past outcomes like these are no guarantee of what comes next.

The record was last updated on 5 October 2026 with an option exercise in Simmons First National Corp. The last insider purchase was made public on 11 August 2025, 439 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction.
