Denise Karkkainen

All filings by Denise Karkkainen on record concern Dirtt Environmental Solutions Ltd, in the capacity of board member. Over a trading history stretching from 18 November 2019 to 2 March 2022, the count stands at 4 filings.

Every open-market trade on record is a purchase: 4 purchases worth €48k, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. In 2022 alone, the filings show 1 purchase and no sales.

In size, the median ticket on the buying side is €13k. Clusters matter here: 4 out of 4 purchases overlapped with buying by a colleague within 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 latest filing, published on 3 March 2022, reports an open-market purchase of €3,347 in Dirtt Environmental Solutions Ltd. Typically, a trade is published a median of 1 day after it takes place. For comparison, the SEC allows two business days to file a Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
