CAMECO CORPORATION vs RIO TINTO PLC, two Mining stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
What is priced in: Rio Tinto at 15.3 times earnings assumes iron ore and copper stay roughly this good; Cameco at 105.3 assumes uranium becomes a decade-long growth market. Rio delivers now, an 11.1% free-cash yield, a 25.9% operating margin, 15.3% returns on equity; Cameco delivers a contracted book and 1.7% cash while its thesis matures. Both are debt-free. The 90-turn spread is the price of certainty about the future minus certainty about the present. Rio's page pays the reader to wait for nothing; Cameco's charges the reader to wait for everything; the sector rarely states the trade this legibly.
