USDA's September WASDE, released Sept. 12, incorporated objective yield plot results for the first time this season.
Corn yield was cut 1.3 bushels to 173.8 bu/acre, and planted area rose to 94.9 million acres, while soybean yields were also reduced.
A lower US corn and soybean yield projection tightens domestic supply, supporting feed grain and meal prices for buyers, though record ear counts partly offset the cut.
After 747 past bullish report events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.1%), and +0.8% over 20.
After 1,040 past bullish report events, Corn moved a median +0.5% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% over 20.
After 414 past bullish report events, Soybean Meal moved a median -0.1% over 5 sessions (48% higher; middle half -2.1% to +2.3%), and +0.3% over 20.
