Corn futures may not be impacted much if today's USDA reports show more acres or larger stocks than anticipated. That's because the CBOT has trended lower in recent weeks, with risk premium from the war with Iran being sold and weather generally supportive for U.S. crops. "The downside risk from here is not believed to be that large regardless of what the report says as funds have already built a large net short and farmer selling interest is limited," says Doug Bergman of RCM Alternatives in a note. Most-active corn is flat premarket. (kirk.maltais@wsj.com)
