DTN previews USDA's Sept. 30 Grain Stocks and Small Grains Summary reports, noting the Sept.
1 corn stocks estimate near 2.436 billion bushels and a record first billion-bushel soybean surplus. Analysts see odds leaning bearish for corn if USDA surprises, as demand has fallen.
A stocks surprise would move corn and soybean prices, and the wheat production estimate will reflect difficult spring wheat harvest conditions.
After 406 past neutral report events, Wheat (SRW) moved a median -0.2% over 5 sessions (47% higher; middle half -1.6% to +1.5%), 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.
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.
