Roald Brouwer: trading record in brief
Roald Brouwer appears in our data through filings on Amrize Ltd shares, published by SIX SER. The record holds 13 filings, for trades running from 8 August 2025 to 11 August 2026.
No open-market sale appears; the market trades are 11 purchases worth €761k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 2 share grants. In 2026 alone, the filings show 4 purchases and no sales.
The median purchase comes to €60k. Of 11 purchases, 11 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.
The latest filing, published on 13 August 2026, reports an open-market purchase of €60k in Amrize Ltd. The median gap between a trade and its publication by SIX SER is 4 days. That lag is the time during which only the insider knows about the trade. This summary is built from SIX SER disclosures alone and does not predict where the share price will go.
