Mark Christopher Greffen

Mark Christopher Greffen discloses dealings in DIRTT Environmental Solutions Ltd. to SEDI. We count 9 filings; the first trade dates from 15 January 2019 and the latest from 17 June 2022.

The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

On 22 June 2022 came the latest disclosure, an option exercise for €27k in DIRTT Environmental Solutions Ltd. The median gap between a trade and its publication by SEDI is 25 days. This delay matters because a trade only becomes useful information once it is public. These figures are compiled from regulatory filings published by SEDI. They describe what insiders did and are not a recommendation.
