1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The US corn market is in a narrow - range oscillation.

The northern port flat - price has increased, while the price in the Northeast may decline, and the price in North China is stabilizing. The price difference between Northeast and North China corn is widening. The wheat price in North China has dropped, and the price difference between wheat and corn is still large, giving corn a cost - performance advantage.
