Grain markets ended October with harvest weather and US-China trade talks as main drivers. Soybeans sold off Friday without a confirmed trade deal, and China reportedly offered to buy $20 billion of US farm goods over 12 months if it wins further tariff cancellations.
Uncertainty over a US-China deal keeps soybean prices volatile, and a confirmed purchase commitment would support soybean and corn demand while the lack of one leaves prices vulnerable to headline-driven selling.
After 250 past neutral trade events, Soybeans moved a median +0.0% over 5 sessions (50% higher; middle half -1.4% to +1.6%), and -0.2% over 20.
After 480 past neutral trade events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
