No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. 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 newest entry dates from 4 April 2023: an option exercise, in Sierra Metals Inc. (formerly Dia Bras Exploration Inc.). Filings reach the SEDI feed a median of 4 days after the trade. Until a filing is published, the market cannot know about the trade. This summary is built from SEDI disclosures alone and does not predict where the share price will go.
