Mark Robert Miller: trading record in brief
This profile gathers the share dealings of Mark Robert Miller in Constellation Software Inc. Over a trading history stretching from 31 December 2015 to 12 December 2025, the count stands at 45 filings.
On the open market, the record shows 2 purchases worth €3.7M and 3 sales worth €69.5M. Taken together, the sales exceed the purchases by €65.8M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 36 share grants. Since January 2025: 2 purchases and no sales on the market.
The newest entry dates from 17 December 2025: an open-market purchase of €3.1M, in Constellation Software Inc. The median gap between a trade and its publication by SEDI is 4 days. The shorter that gap, the sooner other investors can see what insiders have done. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEDI. They describe what insiders did and are not a recommendation.
