Both sides are active: 1 purchase worth €52 and 2 sales worth €18k, from 1 insider and 1 insider respectively. Taken together, the sales exceed the purchases by €18k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

The most recent open-market purchase was published on 26 August 2026, 59 days ago. Between a trade and the moment it shows up on Nasdaq Helsinki, the median delay is 2 days. For comparison, MAR article 19 gives managers three business days to notify a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.
