No open-market sale appears; the market trades are 9 purchases worth €29.3M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. In 2026 alone, the filings show 7 purchases and no sales.

In size, the median ticket on the buying side is €232k. Measured against the company's value, the median purchase equals 0.066% of market capitalisation, across 9 purchases where it is known. On 6 out of 7 purchases, another insider of the same company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. After 6 purchases with a full 90-day history, the hit rate stands at 0% and the median 90-day move at -14.1%. These figures describe past trades and do not predict future prices.

On 22 May 2026 came the latest disclosure, an open-market purchase for €268k in Coffee Stain Group AB. The median gap between trade and publication is zero days: most filings appear on the same day. The legal deadline for notifying a trade is three business days (MAR article 19). Source: insider filings from Finansinspektionen. Past trades are no guide to future returns.
