In open-market terms, that means 5 purchases worth €116k on one side and 31 sales worth €6.2M on the other. On balance, insiders were net sellers of €6.1M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 35 share grants and 19 option exercises.

In size, the median ticket on the buying side is €21k. 3 out of 5 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.

The latest filing, published on 22 May 2026, reports a share grant in Five9, Inc. The most recent open-market purchase was published on 14 August 2025, 433 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
