COMEX Silver futures (SI) are the primary vehicle for trading silver. Silver is more volatile than gold, trading both as a precious metal safe haven and an industrial commodity (electronics, solar panels). Each cent move in silver equals $50 on the standard 5,000 oz contract — fast moves can generate (or cost) significant capital quickly.

COMEX Copper futures (HG) track the price of high-grade copper, often called 'Dr. Copper' for its ability to predict economic activity. Copper is essential in construction, electronics, and EV manufacturing. Rising copper prices often signal economic expansion; falling prices signal contraction.
Micro Gold (MGC) provides gold exposure at one-tenth the standard contract size. With a notional of roughly $20,000, it makes gold futures accessible to retail traders and allows for more precise position sizing.
Platinum futures trade on NYMEX with a 50 oz contract size. Platinum has both precious metal and industrial applications (catalytic converters, hydrogen fuel cells). The platinum-gold spread is closely watched by precious metals traders.
Palladium futures are traded in 100 oz lots on NYMEX. Palladium is primarily used in automotive catalytic converters for gasoline engines. Supply constraints from major producers Russia and South Africa can create volatile price swings.
