David Maxwell Strang: trading record in brief

David Maxwell Strang is a declared insider of Ero Copper Corp., with filings sourced from SEDI. We count 91 filings; the first trade dates from 11 October 2017 and the latest from 28 August 2026.

Sales make up the whole of the open-market record (42 sales). No amount is published for 42 filings, which the totals therefore leave out. Besides market trades, the filings include 6 share grants and 9 option exercises. Since January 2026: no purchases and 4 sales on the market.

The newest entry dates from 29 August 2026: a transaction, in Ero Copper Corp. Filings reach the SEDI feed a median of 3 days after the trade. That lag is the time during which only the insider knows about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEDI disclosures alone and does not predict where the share price will go.
