David Happel: trading record in brief
Filings by David Happel span 2 companies, the busiest being Sagimet Biosciences Inc. and Raptor Pharmaceutical Corp. We count 10 filings; the first trade dates from 9 February 2016 and the latest from 20 July 2026.
In open-market terms, that means 3 purchases worth €66k on one side and 3 sales worth €1.0M on the other. Netting one side against the other leaves €934k of net selling. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 4 share grants. 2026 to date brings no purchases and 2 sales.
Half of the purchases are above €6,093 and half below. The 3 purchases reviewed show no overlap with other insiders buying the same stock within a month.
Most recently, on 22 July 2026, the filings show an open-market sale worth €435k in Sagimet Biosciences Inc. The last purchase on record was published on 28 March 2024, which is 934 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
