1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Report Tin - Supply remains tight with low processing fees and uncertain future supply from Myanmar. Demand is weak, especially in traditional sectors, despite some support from AI and photovoltaic industries. Short - term macro - economic factors may cause price fluctuations. Consider buying on dips due to strong supply - side factors. If Myanmar's supply recovers, prices may weaken; otherwise, prices may remain high and volatile [2]. Aluminum Alloy - Cost support is evident, but raw material supply is tight. Supply is restricted by raw material availability and policy uncertainty, while demand is gradually recovering. Inventory is starting to decline, but the absolute level is still high. ADC12 prices are expected to remain high and volatile in the short term [3]. Alumina - The market is in an oversupply situation. Spot prices are expected to remain under pressure, and the futures main contract may fluctuate between 2750 - 2950 yuan/ton. Key factors to watch include cost - profit changes and policies in resource - rich countries [4]. Aluminum - Macro - economic factors are favorable, providing support for aluminum prices. The fundamental situation is in a tight balance, with supply shortages in some areas and a mixed demand situation. High prices are suppressing downstream procurement. Aluminum prices are expected to remain high and volatile in the short term [4]. Nickel - Macro - economic uncertainties exist. The industry is facing pressure, with nickel - iron prices under stress and shrinking profits. Inventory is increasing, and stainless steel demand is weak. Nickel prices are expected to trade in a range, with the main contract reference range of 120000 - 126000 yuan/ton [5]. Stainless Steel - Macro - economic risks are increasing, and raw material prices are firm, providing cost support. However, downstream demand during the peak season has not met expectations, and inventory is putting pressure on prices. The short - term market is expected to be weak and volatile, with the main contract reference range of 12400 - 12800 yuan/ton [7]. Lithium Carbonate - The futures market is strong, driven by news and strong downstream demand. Production and demand are both increasing, and the industry is in a de - stocking phase. Prices are expected to be strong in the short term, with the main contract price center around 74000 - 76000 yuan/ton [10]. Copper - High copper prices are suppressing demand. Macro - economic factors such as the approaching Sino - US tariff deadline and US employment data may affect prices. Copper supply shortages are a long - term concern, which will support copper prices. The main contract is expected to find support between 84000 - 85000 yuan/ton [12][14]. 3.

1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Methanol - The price may continue to fluctuate under the game of supply and demand. Focus on the stability of overseas device operation, the customs - clearance efficiency of sanctioned vessels, and actual arrival performance. Pay attention to the port destocking rhythm and the implementation effect of overseas gas - limiting expectations [1]. Polyolefins (LLDPE & PP) - The inventory pressure after the holiday is still significant. The supply pressure is prominent in the medium - and long - term, and the demand lacks highlights. The upside space of the 01 contract is limited [5]. Caustic Soda - There is demand support in the medium - and long - term, but it is weak in the short term. It was previously recommended to be bearish, and now the short positions can be temporarily closed as the market stabilizes [8]. PVC - The short - term disk may continue to be under pressure. Although the supply pressure has slightly eased and exports have recovered, the demand in the peak season is weak. Pay attention to cost support and downstream demand performance [8]. PX - The supply and demand are expected to be weak in the fourth quarter. It will mainly fluctuate at a low level in the short term. It is recommended to wait and see and look for short - selling opportunities on rebounds, and mainly conduct reverse spreads on the monthly spread [9]. PTA - The short - term drive is limited, and it will mainly fluctuate at a low level. It is recommended to wait and see TA, pay attention to the support around 4500, and conduct rolling reverse spreads on TA1 - 5 [9]. Ethylene Glycol - It is expected to accumulate inventory in October, and the supply - demand structure is weak in the far - month. It is recommended to short EG01 on rallies, hold the seller of the out - of - the - money call option EG2601 - C - 4350, and conduct reverse spreads on EG1 - 5 [9]. Short Fibers - The absolute price is still under pressure in the short term, but it is relatively strong compared to raw materials due to low inventory. It is recommended to have the same strategy as PTA for the unilateral position, and widen the processing margin at a low level [9]. Bottle Chips - It is likely to enter the seasonal inventory accumulation channel. PR follows the cost end, and the processing margin improves in the short term. It is recommended to have the same strategy as PTA for the unilateral position, and the main contract processing margin is expected to fluctuate between 350 - 500 yuan/ton [9]. Pure Benzene - The overall supply and demand in October are expected to be loose, and the price drive is weak. BZ2603 follows the fluctuations of styrene and oil prices [10].

1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report - The report systematically reviews the price spread between Chinese corn starch and corn from 2021 - 2025, aiming to analyze the profit - gaming logic of the starch industry under the over - supply situation. The main influencing factors of the spread are "cost - supply and demand". The price change of corn at the cost end is the basis for affecting the spread, while the supply - demand relationship of starch is the core driver of the spread's fluctuation. The supply and demand of starch are mainly reflected through processing profit, operating rate, and inventory. High inventory and high operating rate jointly form the greatest downward pressure on the spread, while low inventory and low operating rate are the core drivers for the spread to expand. High inventory limits the upward space of the spread, and industrial concentration strengthens the bottom support of the spread. In the future, the high inventory of starch serves as a major resistance, and the progress of inventory clearance will be a key observation indicator [1][36]. 3. Summary by Related Catalogs 3.1 Corn Starch Industry Chain Situation - Corn starch accounts for about 52% of the deep - processed consumption of corn. Its price is strongly influenced by the cost of corn and its own fundamentals. China's corn starch is mainly self - sufficient, with imports less than 1%. The main production areas are Shandong, Heilongjiang, and Hebei, accounting for 41%, 25%, and 7% respectively [5]. - The supply - related indicators of corn starch include production capacity, operating rate, cost - profit, etc. Downstream consumption is concentrated in starch sugar and papermaking. There is a substitution relationship between starch sugar and white sugar, and the substitution effect is evident when the price difference exceeds 1500 yuan/ton. The price difference between white sugar and F55 high - fructose corn syrup this year has been maintained at a relatively high level of 2500 - 2700 yuan/ton, and the substitution continues. The operating rate of corrugated paper and boxboard is relatively stable, with an annual change of about 5% [6]. 3.2 Corn Starch Production Capacity Changes - In recent years, the production capacity of corn starch has been expanding. In 2024, the production capacity slightly declined to 2630 million tons but still remained in an over - supply situation. The production capacity is mainly concentrated in Shandong, Heilongjiang, Hebei, and Jilin. Since 2020, the industry has witnessed intensified competition, and production capacity has been increasingly concentrated in leading enterprises. The over - supply has compressed industry profits and limited the upward space of the spread, while the concentration has strengthened the bottom support of the spread [9][10][11]. 3.3 Corn Starch and Corn Price Spread Review 3.3.1 2021: Starch Supply - Demand Dominated - The spread showed an M - shaped trend, fluctuating between 300 - 600 yuan/ton. From January to March, the spread widened from 350 to 600 yuan/ton due to high corn prices, limited starch operating rate, and tight inventory. From April to July, it narrowed to around 350 yuan/ton as both corn and starch faced supply - demand pressure. From August to October, it widened again to 600 yuan/ton because of the rebound of corn prices and low starch operating rate. From November to December, it narrowed as starch production increased while demand growth was slower [15][16]. 3.3.2 2022: Strong Cost Support - The spread had a larger amplitude and showed a narrowing trend. From January to February, it expanded from 350 to 580 yuan/ton due to high raw material prices and low operating rate. From March to October, it continuously narrowed to 80 yuan/ton under factors such as weak demand, over - supply, and profit - driven price cuts. From November to December, it fluctuated between 100 - 250 yuan/ton as both corn and starch were in a weak supply - demand balance [19][20]. 3.3.3 2023: Low Operating Rate - The spread showed an oscillating trend with a slowly rising center of gravity. From January to June, it widened to 400 yuan/ton due to stable corn prices and low operating rate caused by continuous losses in processing profit. From July to December, it slightly increased with a shrinking amplitude. In July - August, it narrowed due to high corn prices and weak starch supply - demand. After September, it slightly increased as new - season corn was listed [22][24]. 3.3.4 2024: Weak Supply - Demand - The spread fluctuated between 300 - 500 yuan/ton. From January to May, it first rose and then fell. In January, it reached 500 yuan/ton due to good starch demand and high operating rate. After February, it narrowed to 380 yuan/ton as corn prices rose and processing profit declined. From June to December, it also first rose and then fell. From June to early July, it slightly widened due to limited corn supply and good starch demand. From mid - July to December, it continuously narrowed as new - season corn production was expected to be high and starch inventory accumulated [25][27]. 3.3.5 2025: Supply Pressure - The spread's fluctuation amplitude was about 100 yuan/ton. From January to mid - March, it widened from 300 to 400 yuan/ton as corn prices rose and starch operating rate was high. From late March to early August, it oscillated between 340 - 400 yuan/ton due to corn price fluctuations and weak starch supply - demand. From mid - August to the present, it has been narrowing as new corn was listed, starch inventory remained high, and cassava starch squeezed the demand for corn starch [31]. 3.4 Summary and Outlook - From 2021 - 2025, the spread oscillated with a narrowing range, from 300 - 600 yuan/ton in 2021 to 280 - 400 yuan/ton in 2025, and the high point declined from 600 to 400 yuan/ton. The spread showed seasonal patterns. The spread is mainly affected by "cost - supply and demand", with corn price as the basis and starch supply - demand as the core driver. Starch inventory is a key factor, and "high operating rate + high inventory" is the greatest downward pressure on the spread, while "low operating rate + low inventory" is the core driver for the spread to expand. In the future, the high inventory of starch is a major resistance, and the spread may continue to narrow. Attention should be paid to the change in starch inventory [35][36][40].
