整数关口博弈加剧，供需格局主导后市节奏

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Last week, the corn futures market showed a pattern of falling first and then rising, with the main contract reaching a phased high on Friday. The market sentiment was relatively strong. In the short - term, the market may maintain a moderately strong oscillation. The current strong reluctance of farmers to sell and the obstruction of corn circulation, along with the significant depletion of downstream enterprise inventories and the release of rigid restocking demand, provide support for corn prices. However, the sharp increase in imported corn arrivals in October and the increasing expectation of wheat auctions may have an indirect impact on the corn market demand [8][79].
