Douglas Kerr: trading record in brief
Douglas Kerr (senior executive) discloses dealings in 2 companies, chiefly Generation Bio Co. and Dyne Therapeutics, Inc. In total, 54 filings cover trades dated from 11 January 2021 to 20 October 2026.
Every open-market trade on record is a sale: 27 sales worth €1.6M. Other entries cover 13 share grants and 14 option exercises. In 2026 alone, the filings show no purchases and 6 sales.
The record was last updated on 22 October 2026 with a share grant in Dyne Therapeutics, Inc. The median gap between a trade and its publication by SEC (Form 4) is 3 days. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
