All filings by Thomas Von Koch on record concern DiaMedica Therapeutics Inc. We count 6 filings; the first trade dates from 8 July 2022 and the latest from 23 July 2025.

Both buying and selling appear: 5 purchases worth €19.5M, against 1 sale worth €3.3M. Netting one side against the other leaves €16.1M of net buying. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. 2025 to date brings 1 purchase and no sales.

A typical purchase (the median) is worth €3.3M. 3 out of 4 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.

Most recently, on 25 July 2025, the filings show an open-market purchase worth €8.5M in DiaMedica Therapeutics Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. For comparison, the SEC allows two business days to file a Form 4. Source: insider filings from SEC (Form 4).
