1. Report Industry Investment Rating - Not provided in the content 2. Core Views of the Report - For corn, international price advantage exists, US output outlook is good due to increased planting area and good early - growth rate. In China, Northeast产区 has low remaining grain, strong bullish sentiment, high storage costs for traders, and low selling enthusiasm. Feed demand decreases as wheat is used as a substitute. The futures market is in a volatile state, and short - term participation is recommended [2][3] - For corn starch, production losses lead to low industry operating rates. Supported by reduced supply pressure and firm corn prices, the spot price performs well, and inventory continues to decline. The futures market is also volatile, and short - term participation is recommended [4] 3.

1. Report Industry Investment Rating - No relevant information provided 2. Core Views of the Report - For corn, the good condition of US corn and the easing of trade relations between China and the US have led to concerns about long - term import pressure.

1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - For corn, the domestic Northeast region's mid - month rotation acquisition by Sinograin supports the spot market, but increased auction supply, weakening futures, and compressed profits of deep - processing enterprises lead to a downward adjustment of purchase prices. In the North China and Huanghuai regions, new wheat harvesting and the price proximity of wheat and corn reduce corn demand. The corn futures price has recently declined and short - term trading is recommended [2][3]. - For corn starch, due to high raw material costs, large industry losses, and competition from substitutes, the industry's operating rate is decreasing. The spot price is relatively firm, but downstream demand is limited, and inventory remains high. The starch futures price has been weak recently, and short - term trading is also recommended [3]. 3.
