Sales make up the whole of the open-market record (8 sales, €1.2M). Outside the open market, there are 7 share grants. 2026 to date brings no purchases and 1 sale.

The record was last updated on 13 August 2026 with an open-market sale (€184k) in Zai Lab Ltd. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
