Commodity investments involve purchasing physical goods or financial contracts linked to raw materials, such as gold, oil, corn, or copper. Investors typically buy these commodities to diversify their portfolios, hedge against inflation, or capitalize on price fluctuations in the market. Investing in commodities can be done through various methods, including direct purchase of the physical goods, trading in futures contracts, or investing in exchange-traded funds (ETFs) that focus on commodities. These investments can be influenced by factors like supply and demand, geopolitical events, and changes in economic conditions.
