Filings by Katriina Tahkola span 2 companies, the busiest being Talenom Oyj and Easor Oyj. Over a trading history stretching from 31 August 2022 to 28 February 2026, the count stands at 5 filings.

The open-market record is one-sided, with 4 purchases worth €94k and not one sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price.

A typical purchase (the median) is worth €22k. As a share of market capitalisation, the median purchase stands at 0.046%, based on 3 purchases. 2 out of 4 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 4 March 2026, the filings show a transaction in Easor Oyj. The latest purchase dates back some time: it was published 306 days ago, on 22 December 2025. Typically, a trade is published a median of 1 day after it takes place. The regulation allows three business days to notify a trade (MAR article 19). These figures are compiled from regulatory filings published by Nasdaq Helsinki. They describe what insiders did and are not a recommendation.
