On the market, this insider has only sold: 33 sales, €4.6M in total. No amount is published for 2 filings, which the totals therefore leave out. Other entries cover 6 share grants and 9 option exercises. So far in 2026, the count stands at no purchases and 5 sales.

On 18 September 2026 came the latest disclosure, an open-market sale for €114k in Ambarella Inc. 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. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
