Report Industry Investment Rating - Not provided in the content 2. Core Views of the Report - The USDA's December report showed an increase in US corn exports and a decrease in inventory, but the production remains at a high level, so US corn is expected to fluctuate strongly. Domestic corn has different trends in different regions, with Northeast corn being relatively strong and North China corn being weak recently. The spot price of corn is expected to be relatively stable in the short - term, but there is still a risk of decline due to the potential seasonal selling pressure in Northeast China and the situation of downstream inventory building. Corn starch inventory has increased this week, and due to the relatively strong price of corn and weak price of starch, corporate profitability has declined. The short - term 03 starch futures contract is expected to fluctuate weakly [4][6][7]. 3.

The import profit of foreign corn has increased, and the price of Brazilian imports in February is 2159 yuan. The FOB price at northern ports has risen, and the spot price in Northeast China is relatively strong. The supply in North China has increased, and the spot price is weak. The price difference between Northeast and North China corn has narrowed. The wheat price in North China is stable, and the price difference between wheat and corn is still large, so corn has a cost - performance advantage. Domestic breeding demand is stable, and the inventory of downstream feed enterprises has increased. The spot price of corn is expected to be relatively stable in the short - term, but the market is concerned about the seasonal selling pressure of Northeast corn before the Spring Festival and the situation of downstream inventory building [4][6]. Starch - The number of trucks arriving at Shandong deep - processing plants has increased, and the spot price of corn in Shandong is weak. The spot price of starch in Northeast China is stable. This week, the corn starch inventory has increased to 110.2 million tons, an increase of 2.8 million tons from last week, with a monthly increase of 3.1% and a year - on - year increase of 25.4%. The starch price mainly depends on the corn price and downstream stocking. The by - product price is still strong, and the spot price difference between corn and starch is low. Due to the relatively strong corn price and weak starch price, corporate profitability has declined. The 03 starch futures contract has followed the increase of corn, but the corn price in North China may decline in January, and the spot price of corn starch is also expected to decline later. The short - term 03 starch futures contract is expected to fluctuate weakly [7]. 3.3 Trading Strategies - Unilateral: The 03 US corn has support at 430 cents per bushel. Close the long position of 07 corn. - Arbitrage: Wait and see [8][9][10]. 3.4 Corn Options - Option strategy: Use the short - term cumulative put strategy and conduct rolling operations [11]. 3.5 Relevant Attachments - The attachments include charts of corn spot prices in various regions, corn 01 contract basis, corn 1 - 5 spread, corn starch 1 - 5 spread, corn starch 01 contract basis, and corn starch 01 contract spread [15][17][19].
