December corn closed up 10.25 cents at $4.30 on September 12 after USDA's Crop Production report put yield at 186.7 bushels per acre, down 2.1 from August. Planted acreage was raised to a near-record 98.728 million, lifting production 73 million bushels to 16.814 billion.
A lower yield estimate tightens the supply outlook, though higher acreage and production keep the balance sheet heavy, leaving corn modestly supported.
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.
