Every open-market trade on record is a sale: 2 sales worth €214k. Besides market trades, the filings include 1 option exercise. So far in 2025, the count stands at no purchases and 2 sales.

The latest filing, published on 5 May 2025, reports an open-market sale of €210k in Sienna Resources Inc. Typically, a trade is published a median of 5 days after it takes place. This delay matters because a trade only becomes useful information once it is public. 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.
