N. Björkman: trading record in brief

N. Björkman appears in our data through filings on Avantium N.V. shares, published by AFM. Over a trading history stretching from 25 January 2022 to 22 September 2025, the count stands at 10 filings.

Market trades split into 8 purchases (€111k) and 1 sale. The totals do not cover 5 filings with an undisclosed amount. 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 2 purchases and 1 sale.

In size, the median ticket on the buying side is €31k. On 2 out of 4 purchases, another insider of the same company was buying within the same 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The record was last updated on 22 September 2025 with an open-market purchase (€38k) in Avantium N.V. Every figure here comes from the filings published by AFM and describes the past, not future prices; it is not investment advice.
