On the market, this insider has only ever bought: 4 purchases, €325k in total. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. 2026 to date brings 1 purchase and no sales.

In size, the median ticket on the buying side is €80k. Relative to company size, the median is 0.0004% of market cap (4 purchases with a known value). Of 4 purchases, 3 formed part of a group of insiders buying within 30 days of each other. 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 13 August 2026 with a transaction (€2.0M) in Wärtsilä. The clock since the last published purchase (7 May 2026) now reads 163 days. 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). This summary is built from Nasdaq Helsinki disclosures alone and does not predict where the share price will go.
