Jan Bertus Marten Warntjes: trading record in brief

Jan Bertus Marten Warntjes is a declared insider of SyntheticMR AB (board member), with filings sourced from Finansinspektionen. The record holds 3 filings, for trades running from 30 May 2017 to 1 July 2025.

Sales make up the whole of the open-market record (3 sales, €4.0M). Since January 2025: no purchases and 1 sale on the market.

The latest filing, published on 3 July 2025, reports an open-market sale of €325 in SyntheticMR AB. The median gap between a trade and its publication by Finansinspektionen is 2 days. The regulation allows three business days to notify a trade (MAR article 19). A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by Finansinspektionen. They describe what insiders did and are not a recommendation.
