Southern Copper looks expensive against its sales. At $203.92 and a $172.2 billion market cap, it trades about 98% above the high end of a $80.84-102.89 fair value range based on 5x mid-cycle sales. It also trades at 28x forward earnings, 11x EV/sales and a PEG of 5.41. x.com 

Teck Resources looks expensive against its earnings, trading at 20x when copper miners usually get about 13x. At 13x next year's estimated $3.61 per share, give or take 12%, fair value is $41.26 to $52.52, so the stock trades about 37% above fair. This is a valuation-levels call only, based on reported earnings and revenue estimates rather than fundamental work. x.com 

Copper's structural deficit does not yet look priced in, with the copper/gold ratio still near multi-decade lows. JPMorgan forecasts a 330kt copper deficit in 2026, AI data centers may need over 1 million tons a year by 2030, EVs use about 4x the copper of gas cars, new mines take 15-20 years to build, and ore grades have declined for decades. x.com 

Copper is one of the clearest trades over the next three years because supply is worse than most realize while AI accelerates demand. Chile, about a quarter of global production, just hit a nine-year production low, and copper miners have held up far better than silver and gold. Deutsche Bank forecasts copper soaring 50% to $22,050 a ton. x.com 

Copper will follow the AI trade lower, making it a good catch-up short. x.com 

Hudbay Minerals may be one of the most overlooked copper names. It posts record EBITDA and cash flow on strong copper and gold production, and benefits from demand tied to AI, data centers, EVs and grid infrastructure. The stock is setting up to break out of a 20-year base. x.com  x.com 

Copper miners stand to benefit from a massive undersupply of copper right now, making the copper miners ETF a candidate for selling puts. x.com 

Freeport-McMoRan is an excellent way to capture a structural commodities bull market. Goldman Sachs, in its first Buy rating, calls it the best exposure to a structural copper shortage, plus gold. Per Goldman, electrification lifts copper demand 2.1% a year to 2030 while falling ore grades raise costs. Grasberg's gold by-product and US leaching at about $1 a pound, aiming for 800 million pounds a year by 2030, could lift EBITDA margins above 50% and fund $19 billion-plus of free cash flow. x.com 

Copper miners stand to gain as the massive AI infrastructure buildout drives copper demand sharply higher through 2027, continuously pushing prices up; now is an excellent buying opportunity. LME copper topped $14,000/ton and COMEX $6.65/lb on rebounding Chinese demand, tight Middle East sulfur supply and AI data-center power needs. A 350,000-ton global shortfall is projected for 2026, and miners offer 2-3x leverage to copper price moves. x.com 

Freeport-McMoRan can grow copper output at high margins without building new mines, using proprietary leaching and heated solution injection in Arizona. These already add over 200 million pounds a year, with longer-term targets of 400-800 million. Barclays initiated at Overweight with a $77 target and UBS raised its target to $75. AI data centers, grid upgrades and a forecast copper deficit drive demand, while gold by-product credits lower net copper costs. x.com
