Wheat is considered a commodity investment because it is a globally traded agricultural product used as a staple food and as an ingredient in many consumer goods. The price of wheat is influenced by supply and demand factors such as weather conditions, crop yields, and geopolitical events. As a result, investing in wheat can provide exposure to changes in the price of the commodity and potentially offer returns to investors. Wheat can be invested in through futures contracts, ETFs, or stocks of companies in the agriculture sector.
