Katharine Weymouth: trading record in brief
Filings by Katharine Weymouth span 4 companies, the busiest being Xometry, Inc., Republic Services, Inc. and Cable One, Inc. In total, 33 filings cover trades dated from 21 May 2021 to 31 August 2026.
Market trades split into 7 purchases (€315k) and 6 sales (€2.2M). Netting one side against the other leaves €1.9M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 11 share grants and 7 option exercises. Since January 2026: 1 purchase and 2 sales on the market.
The median purchase comes to €42k. Clusters matter here: 2 out of 7 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.
The latest filing, published on 31 August 2026, reports an option exercise of €19k in Xometry, Inc. The last insider purchase was made public on 2 March 2026, 230 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
