On the market, this insider has only ever bought: 4 purchases, €294k in total. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 8 share grants and 1 option exercise. Since January 2025: 1 purchase and no sales on the market.

A typical purchase (the median) is worth €70k. 1 out of 4 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. Ninety days after publication, 4 purchases show a median change of -4.0%, with the price up in 50% of them. Past outcomes like these are no guarantee of what comes next.

Most recently, on 19 August 2025, the filings show an open-market purchase worth €60k in Mercantile Bank Corp. Typically, a trade is published a median of 3 days after it takes place. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
