Option Greeks measure how an option's price responds to changes in the stock price (delta and gamma), time (theta), implied volatility (vega), and interest rates (rho).

Gamma, theta, and vega are largest for strikes near the Freeport-McMoran stock price and shrink for strikes far above or below it. Theta grows as expiration gets closer, while vega is larger for expirations further out. Call delta runs from 0 to 1 and put delta from -1 to 0, near 0.50 and -0.50 at the money, and roughly estimates the chance that an option finishes in the money.

Freeport-McMoran IV rank is 41, so implied volatility is near the middle of its one-year range. Higher implied volatility raises option premiums and daily time decay (theta), and spreads delta and gamma across a wider range of strikes. Over the past year, 30-day implied volatility ranged from 32.9% to 63.8%. See the FCX implied volatility history for a longer view.

Across all open Freeport-McMoran options on Nov 4, 2026, net gamma exposure was $412.46K and net delta exposure was $137.74M per 1% move in the stock. The FCX gamma exposure chart shows where that gamma sits by strike.

Freeport-McMoRan owns stakes in 10 copper mines, led by its 49% ownership of the Grasberg copper and gold operations in Indonesia, 56% of the Cerro Verde mine in Peru, and 72% of Morenci in Arizona.
