Steven M. Chaouki

Steven M. Chaouki is a declared insider at 2 companies (chief executive); the most frequent names are TransUnion and MAIA Biotechnology, Inc. In total, 57 filings cover trades dated from 7 May 2021 to 15 October 2026.

In open-market terms, that means 4 purchases worth €155k on one side and 35 sales worth €3.9M on the other. The net balance comes to €3.7M on the selling side. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 18 share grants. Since January 2026: no purchases and 7 sales on the market.

The median purchase comes to €40k. Clusters matter here: 4 out of 4 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The record was last updated on 16 October 2026 with an open-market sale (€62k) in TransUnion. The last purchase on record was published on 23 December 2025, which is 299 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. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
