Market Analysis - **Corn**: Crude oil is at a high level, US corn prices are rising, and the global corn supply pressure has weakened, so US corn will continue to oscillate strongly. The import profit of foreign corn has increased, with the import price from Brazil in July at 2372 yuan. The closing prices at northern ports are stable, around 2400 yuan, and the spot prices in Northeast corn - producing areas are also stable. The supply of corn for deep - processing has decreased, and the spot price of corn is stable, with the price difference between North China and Northeast corn widening. Wheat and corn auctions are ongoing, the price of North China wheat is rising, around 2600 yuan per ton, the price difference between wheat and corn is narrowing, and the cost - effectiveness of corn is weakening, with wheat being relatively stronger in the short term. The domestic breeding demand is average, the inventory of downstream feed enterprises has increased, and the downstream is replenishing stocks, so the corn spot price is relatively strong in the short term. Recently, the supply of Northeast corn has increased, the downstream and traders are replenishing stocks, the price is stable, the port inventory has increased, the purchase price at the northern port is stable today, and the North China corn price is also stable.

In the past few years, the average income from by - products has been over 600 yuan, and today the by - product contribution in Shandong is 667 yuan (732 yuan in Heilongjiang). Recently, the by - product price has been relatively strong, higher than last year, and the spot price difference between corn and starch is at a low level. North China corn is relatively strong in the short term, while Northeast corn is relatively stable. The supply of corn is expected to increase, the downstream operating rate is increasing, the upward space for the corn spot price is limited, and enterprises are already profitable. The 05 starch contract is oscillating narrowly following corn, and with North China corn remaining strong, the upward space for the starch spot price is limited in the short term. It is expected that the 05 starch contract will oscillate at a high level in the short term [6].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The US corn market is experiencing a bottom - side oscillation. The US corn 12 - contract is expected to have limited downside below 400 cents per bushel. Corn auctions are ongoing, and with the upcoming new - season corn harvest in September, the market anticipates that Shandong corn prices may drop below 2,200 yuan/ton when a large amount of North China corn hits the market in mid - October. The 09 corn contract may trade in a narrow range around 2,250 yuan/ton, while the 01 corn contract may decline to around 2,150 yuan/ton under favorable weather conditions. The 09 starch contract is expected to remain weak due to its high price differentials with corn and the 01 starch contract [4]. - For trading strategies, one can consider buying the US corn 12 - contract below 400 cents per bushel, buying the 01 corn contract around 2,150 yuan/ton, and paying attention to the 9 - 1 starch reverse spread opportunity (around 100) and the opportunity to narrow the spread between the 09 corn and starch contracts (420 - 380). Options trading should be on hold [5]. 3. Summary by Directory 3.1 Chapter 1: Comprehensive Analysis and Trading Strategies - **Corn Situation**: The US corn is at the bottom and oscillating, with the price significantly below the cost (480 cents per bushel). The 12 - contract is expected to have limited downside below 400 cents per bushel. As of August 8, 2.89 million tons of corn were up for auction, with 1.18 million tons sold, a 41% success rate. High 09 - contract warehouse receipts (1.5 million tons), reduced domestic planting costs, and large losses in deep - processing industries are causing domestic corn spot prices to decline. The market is shifting focus to new crops, especially in North China, where it is expected that North China corn prices will likely fall below 2,200 yuan/ton in October. The 09 corn contract may trade narrowly around 2,250 yuan/ton, and the 01 corn contract may drop to 2,150 yuan/ton under good weather [4]. - **Starch Situation**: Starch factory operating rates are rising, but downstream demand remains weak. Although corn spot prices are falling, starch spot prices are also dropping, and starch factories are still facing large losses. The operating rates of North China starch enterprises will decline later, and with the upcoming new - corn harvest, North China starch prices will continue to fall. The 09 starch contract is expected to remain weak due to its high price differentials [4]. - **Trading Strategies**: - **Unilateral Trading**: Consider buying the US corn 12 - contract below 400 cents per bushel. The 09 corn contract may trade in a narrow range of 2,230 - 2,280 yuan/ton, and the 01 corn contract can be bought around 2,150 yuan/ton [5]. - **Arbitrage**: Pay attention to the 9 - 1 starch reverse spread opportunity around 100 and the opportunity to narrow the spread between the 09 corn and starch contracts (420 - 380) [5]. - **Options**: Hold off on options trading [5]. 3.2 Chapter 2: Core Logic Analysis 2.1 International Market - **US Corn Weather and Supply - Demand**: Favorable weather conditions are contributing to the bottom - side oscillation of US corn.
