COPP aims to replicate an index comprised of 30 to 50 constituents with a significant portion of their revenue derived from copper mining, exploration, development, and production activities. Eligible securities must meet specific criteria, including minimum free float market capitalization and an Average Daily Traded Value threshold. Companies then undergo a selection process involving industry publications, research, and engagements with company management. Securities are weighted based on free float market capitalization, with excess weight redistributed among other constituents, ensuring portfolio diversification and preventing undue influence by individual companies. The index includes securities from domestic and international issuers, covering emerging and frontier markets, with notable representation from Canadian, Chilean, and Australian issuers. Reconstitution and rebalancing occur semi-annually, with deletions possible at any time due to corporate actions. COPP may also invest in publicly traded closed-ended trusts within the index's purview.
