Trading corn futures is similar to corn farming, in that they both must pay close attention to seasons and the weather. Trading corn futures can be fairly subdued during the winter months, while the summer months are not for the faint of heart. Corn is planted in the spring and harvested in the fall, and this growing season is when most of the action in corn prices takes place. The movement during the winter months usually stems from demand and how much of the harvested crop is sold every week. During the summer months, corn traders carefully watch every updated weather report for any potential weather problems in corn-growing areas. This report is released at the end of March.
