Commodities are exchanged on international exchanges, which frequently focus on a small number of commodities or a group of them. All commodity classes, including metals, energy, food, and livestock, are available for trading on OzoneMarkets. Futures contracts, which are agreements to purchase or sell a specific commodity at a predetermined price at a specific point in the future, are the most widely used form of commodity trading. Options on futures, equities, and ETFs/ETNs can also be used to purchase commodities. Trading commodities can help steady your portfolio because their price movement often veers away from that of stocks.
