Filings by Stefan Vitorovic span 3 companies, the busiest being Vigil Neuroscience, Inc., Praxis Precision Medicines, Inc. and Tectonic Therapeutic, Inc. Over a trading history stretching from 20 October 2020 to 5 August 2025, the count stands at 11 filings.

Every open-market trade on record is a purchase: 3 purchases worth €24.7M, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 3 share grants.

A typical purchase (the median) is worth €4.0M. Clusters matter here: 3 out of 3 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The newest entry dates from 5 August 2025: a transaction, in Vigil Neuroscience, Inc. The clock since the last published purchase (11 January 2022) now reads 1,746 days. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
