Peter Feinberg: trading record in brief
Peter Feinberg, listed as board member, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Immuneering Corp and Notable Labs, Ltd. The record holds 12 filings, for trades running from 3 August 2021 to 12 January 2026.
On the market, this insider has only ever bought: 10 purchases, €647k in total. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 1 share grant. Since January 2026: 1 purchase and no sales on the market.
A typical purchase (the median) is worth €57k. On 7 out of 10 purchases, another insider of the same company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.
Most recently, on 14 January 2026, the filings show an open-market purchase worth €75k in Immuneering Corp. Typically, a trade is published a median of 2 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
