Foresite Labs, LLC: trading record in brief
Foresite Labs, LLC discloses dealings in Alumis Inc. to SEC (Form 4). In total, 10 filings cover trades dated from 1 July 2024 to 1 April 2026.
Every open-market trade on record is a purchase: 5 purchases worth €2.6M, and no sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. So far in 2026, the count stands at 1 purchase and no sales.
Half of the purchases are above €241k and half below. Clusters matter here: 5 out of 5 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. After 3 purchases with a full 90-day history, the hit rate stands at 100% and the median 90-day move at +267.5%. These figures describe past trades and do not predict future prices.
The record was last updated on 3 April 2026 with a transaction in Alumis Inc. The latest purchase dates back some time: it was published 279 days ago, on 12 January 2026.
