Stifel’s latest note urges investors to look ahead, not just the present, as copper markets shift toward a supply‑driven 2026. The firm flags legacy supply fragility and a 9% decline in the top 20 mines’ grade over two decades, warning that smelters face a tight concentrate market for future trading.

Despite record copper prices, Stifel argues that sector valuations still favor buying over building new supply. The brokerage names three top picks, noting that smaller, high‑grade projects like Foran’s 2026 ramp can expand profit margins faster than larger Canadian mines, offering a quicker path to throughput for investors in 2026.

Looking ahead, analysts warn that a tight concentrate market could squeeze treatment charges, while legacy supply limits new output. Investors should monitor permitting milestones at Meridian Mining and the ramp‑up pace of Foran’s mine, as these developments could reshape copper’s supply curve in the coming years for long‑term investors in.
