Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - The U.S. corn market is in a narrow - range oscillation. Although the Sino - U.S. relations have eased recently and the price has rebounded, the production remains high. The import profit of foreign corn has declined. The domestic corn spot is relatively strong in the short - term, with stable production areas, reduced supply in North China, and strong demand from downstream feed enterprises. The starch price is mainly affected by corn price and downstream stocking. The inventory has increased this week, and the 01 starch follows the corn to oscillate strongly, but there is a possibility of decline later [3][5][6] - The trading strategy suggests that the U.S. corn is expected to continue to oscillate narrowly. The 05 and 01 corn can be put on hold for now, and the spread between 01 corn and starch can be shorted when it is high. For options, a short - term strategy of accumulating puts and calls with rolling operations is recommended [7][8][10] Group 3: Summary by Directory 1. Data - **Futures Disk Data**: The closing prices, price changes, price change percentages, trading volumes, trading volume change percentages, open interests, and open interest change percentages of multiple futures contracts such as CS2605, CS2509, C2601, etc. are provided. For example, the closing price of CS2605 is 2164, with a price increase of 15 and a price change percentage of 0.69%, the trading volume is 549,821 with an increase of 20.06%, and the open interest is 966,186 with a decrease of 1.11% [1] - **Spot and Basis Data**: The spot prices of corn in different regions such as Qinggang, Songyuan Jiji, Zhucheng Xingmao, etc., and the spot prices of starch of different brands such as Longfeng, COFCO, Cargill, etc. are given. Also, the basis data of corn and starch are provided [1] - **Spread Data**: The spreads and their changes of corn inter - period, starch inter - period, and cross - variety are presented. For example, the C01 - C05 spread of corn is - 86 with a change of 6, and the CS01 - CS05 spread of starch is - 93 with a change of 5 [4] 2. Market Judgment - **Corn**: The U.S. corn is in a narrow - range oscillation. The domestic corn has a relatively strong spot in the short - term. The production areas are stable, the supply in North China has decreased, and the price is relatively strong. The price difference between Northeast and North China corn is large. The wheat price in North China is weak, and the corn has cost - effectiveness. The domestic breeding demand is stable, and the inventory of downstream feed enterprises is low. The corn in Northeast China is relatively strong, and the purchase price in the northern port is strong. It is expected that the price of North China corn will be supported at around 2150 yuan/ton, and the 01 corn oscillates strongly [3][5] - **Starch**: The number of trucks arriving at deep - processing plants in Shandong has decreased, and the corn spot in Shandong is stable. The starch inventory has increased this week, with the manufacturer's inventory at 113.8 million tons, a monthly increase of 0.89% and a year - on - year increase of 33.26%. The starch price mainly depends on the corn price and downstream stocking. The by - product price is strong, and the enterprise profit is good. The 01 starch follows the corn to oscillate strongly, but the corn in North China may decline in November, and the starch spot may also decline later [6] 3.

The supply in North China has increased, and the corn spot has started to stabilize. The spread between Northeast and North China corn has widened. The wheat price in North China is stable, and the wheat - corn spread is large. The domestic breeding demand is stable, but the corn spot still has short - term downward space [4][6]. 3.2.2 Starch - The number of trucks arriving at Shandong deep - processing plants has increased, and the Shandong corn spot is stable. The starch inventory has increased this week, with the manufacturer's inventory at 113.8 million tons, an increase of 1.0 million tons from last week, a monthly increase of 0.89% and a year - on - year increase of 33.26%.
