The profit of a company at time T = 1 is given by ST - $1,780, per ounce of gold, where ST is the price of gold at time T and $1,780 is the production costs (also time-T value). Suppose company wants to hedge its exposure to gold price risk using two options at the same time: a gold put option with strike price $1,820 and a gold call option with strike price $1,840.
