Jerome Benedict Durso: trading record in brief
Jerome Benedict Durso (chief executive) discloses dealings in 2 companies, chiefly Intercept Pharmaceuticals, Inc. and Altimmune, Inc. Between 1 July 2021 and 13 August 2026, the trades on record add up to 11 filings.
On the market, this insider has only ever bought: 4 purchases, €184k in total. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 6 share grants. In 2026 alone, the filings show 3 purchases and no sales.
A typical purchase (the median) is worth €42k. 2 out of 4 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
The latest filing, published on 13 August 2026, reports an open-market purchase of €38k in Altimmune, Inc. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
