Brett Matthew Hall: trading record in brief
Brett Matthew Hall (senior executive) discloses dealings in Immuneering Corp to SEC (Form 4). Over a trading history stretching from 3 August 2021 to 15 January 2026, the count stands at 11 filings.
On the market, this insider has only ever bought: 7 purchases, €91k in total. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 3 share grants. Since January 2026: 1 purchase and no sales on the market.
A typical purchase (the median) is worth €13k. On 7 out of 7 purchases, another insider of the same company was buying within the same 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 January 2026 with an open-market purchase (€9,017) in Immuneering Corp. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
