Karen Bomba (board member) discloses dealings in Wärtsilä to Nasdaq Helsinki. Over a trading history stretching from 22 July 2022 to 7 May 2026, the count stands at 5 filings.

No open-market sale appears; the market trades are 5 purchases worth €162k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. In 2026 alone, the filings show 1 purchase and no sales.

The median purchase comes to €32k. Scaled by market value, the purchases weigh a median 0.0002% of market cap (sample: 4 purchases). 4 out of 5 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

Most recently, on 7 May 2026, the filings show an open-market purchase worth €34k in Wärtsilä. Most trades are made public on the day they happen. The legal deadline for notifying a trade is three business days (MAR article 19). These figures are compiled from regulatory filings published by Nasdaq Helsinki. They describe what insiders did and are not a recommendation.
