Metals trade across three broad categories. Precious metals — gold, silver, platinum, and palladium — are held primarily as inflation hedges and stores of value, though platinum and palladium carry heavy industrial demand from catalytic converters. Base metals like copper trade on global growth and electrification cycles. And nuclear fuel in the form of uranium has re-emerged as an investable theme with the restart of dormant reactors and the build-out of small modular reactors (SMRs) for AI-data-center electricity.
The four traditional precious metals are gold, silver, platinum, and palladium. Gold and silver are the most widely held as investments; platinum and palladium are more industrial — they're heavily used in catalytic converters and in some chemical applications.
Most US investors gain exposure through ETFs: GLD and IAU for gold; SLV for silver; CPER for copper; PPLT and PALL for platinum and palladium; URA, URNM, and URNJ for uranium. Miner-equity ETFs (GDX, GDXJ, SIL, SILJ, COPX) provide leverage to the underlying metal price but add operational risk. Direct ownership of physical bullion and futures contracts are other channels.
Precious metals like gold and silver move with real interest rates, US-dollar strength, and risk-off sentiment. Industrial metals like copper track global growth, construction, and electrification demand. Platinum-group metals are tied to auto-production cycles. Uranium is driven by nuclear policy, reactor uptime, and long-term utility contracts.
