Heather Cox

Heather Cox is a declared insider at 4 companies (senior executive); the most frequent names are NRG Energy, Inc., Atlantic Union Bankshares Corp and American Bitcoin Corp. In total, 38 filings cover trades dated from 3 May 2021 to 3 August 2026.

The open-market record is one-sided, with 3 purchases worth €93k and not one sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 32 share grants and 3 option exercises.

The median purchase comes to €37k. Clusters matter here: 2 out of 3 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.

Most recently, on 5 August 2026, the filings show a share grant in NRG Energy, Inc. The latest purchase dates back some time: it was published 642 days ago, on 15 January 2025. 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. Source: insider filings from SEC (Form 4).
