Report Industry Investment Rating No relevant content provided. Core Viewpoints - The report suggests short - term trading for both corn and corn starch. For corn, although the pressure on the import side has decreased due to the non - listing of Brazil's second - crop corn, the expected increase in the US corn ending stocks in the 2025/26 season and concerns about long - term import pressure may restrict prices. In the domestic market, the situation varies by region, and the spring sowing progress in some areas is slower than last year. For corn starch, the supply pressure has declined due to the decrease in the operating rate of enterprises, but the downstream demand is weak, and the inventory remains high [7][8][11][12].
