William Roy Johnstone

William Roy Johnstone appears in our data through filings on Gratomic Inc. (formerly CKR Carbon Corporation) shares, published by SEDI. We count 3 filings; the first trade dates from 10 December 2019 and the latest from 1 February 2023.

The filings describe grants, exercises and other transfers rather than trades on the open market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

The latest filing, published on 2 February 2023, reports a transaction of €21k in Gratomic Inc. (formerly CKR Carbon Corporation). Between a trade and the moment it shows up on SEDI, the median delay is 5 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.
