David Brereton: trading record in brief

David Brereton is a declared insider of Tecsys Inc., with filings sourced from SEDI. We count 31 filings; the first trade dates from 5 June 2026 and the latest from 16 October 2026.

Every open-market trade on record is a sale: 24 sales worth €250k. The rest of the record consists of 2 option exercises.

The newest entry dates from 16 October 2026: an open-market sale of €12k, in Tecsys Inc. Filings reach the SEDI feed a median of 3 days after the trade. That lag is the time during which only the insider knows about the trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
