Zaner Group's Brian Grossman said analysts expect USDA's Grains and Oilseeds Outlook to raise trend-line yield estimates, with corn near 174 bushels and soybeans 47-48. He said the report would likely be bearish if higher yields are adopted.
Higher trend yields imply larger projected supplies and lower ending stocks pressure, which would be bearish for corn and soybean futures and feed costs.
After 1,102 past bearish report events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.8% to +1.3%), and +0.0% over 20.
After 788 past bearish report events, Soybeans moved a median -0.3% over 5 sessions (47% higher; middle half -2.0% to +1.5%), and -0.9% over 20.
