1. Report Industry Investment Rating No relevant content provided in the reports. 2. Core Views of the Reports Polyester Industry Chain - PX: The supply increment is obvious due to short - process losses and postponed maintenance of some domestic PX plants. The supply - demand outlook in the fourth quarter is weak, and PXN is expected to compress. Suggest to treat PX11's rebound with a short - bias and focus on the support around 6500 [2]. - PTA: Supply is expected to shrink due to low processing fees and postponed new plant commissioning. However, demand growth is limited, and the basis is weakly volatile. Suggest to treat TA's rebound with a short - bias and focus on the support around 4500; conduct a rolling reverse spread on TA1 - 5 [2]. - Ethylene Glycol (MEG): Supply - demand is gradually weakening. It will enter the inventory accumulation phase in the fourth quarter. Suggest to sell call options EG2601 - C - 4400 at high prices and conduct a reverse spread on EG1 - 5 [2]. - Short - fiber: The short - term supply - demand pattern is weak. It has support at low levels but weak rebound drivers. The strategy is the same as PTA, and the processing fee on the disk fluctuates between 800 - 1000 [2]. - Bottle chips: The supply - demand is loose. PR follows the cost side. Suggest that the strategy for PR is the same as PTA, and the processing fee on the main disk is expected to fluctuate between 350 - 500 yuan/ton [2]. Chlor - alkali Industry - Caustic Soda: The market in Shandong may see price cuts in the short - term. It can be shorted in the short - term [29]. - PVC: The market is weakly volatile. Supply is expected to increase next week, and demand growth is limited. It is expected to stop falling and stabilize during the peak season from September to October. Pay attention to downstream demand [29]. Pure Benzene and Styrene Industry - Pure Benzene: Supply remains at a relatively high level, and demand support is weak. In the short - term, the price is affected by geopolitical and macro factors. Suggest that BZ2603 follows the fluctuations of styrene and crude oil [31]. - Styrene: Demand is fair but with limited growth. Supply is expected to decrease. The absolute price is under pressure. Suggest to treat EB11's rebound with a short - bias and expand the spread between EB11 and BZ11 at low levels [31]. Urea Industry - Urea: The futures price is weakly running due to the contradiction between high supply and weak demand. The supply - demand pattern is likely to remain weak in the future. The price may continue to be under pressure, but it may form a bottom support near the production cost [39]. Polyolefin Industry - LLDPE and PP: PP production has decreased recently, and PE inventory has been destocked. The 01 contract may face large inventory accumulation pressure, limiting the upside space [43]. Methanol Industry - Methanol: The market is trading high inventory and fast Iranian shipments. The price is weakening, and the basis is slightly weakening. The overall valuation is neutral. Pay attention to the inventory inflection point [46]. Crude Oil Industry - Crude Oil: The overnight oil price fell due to concerns about supply surplus outweighing geopolitical risk premiums. The fundamental outlook is bearish. Suggest to wait and see on the single - side trading, and look for opportunities to expand the spread on the option side after the volatility increases [52]. 3.

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - Last week, the subsidy for liquid chlorine in Shandong was alleviated, but due to the significant decline in caustic soda prices, the profit of chlor - alkali in Shandong contracted on a month - on - month basis. The chlor - alkali maintenance plan in September was basically fulfilled. This week, multiple units such as Xinpu Chemical, Gansu Jinchuan, and Heilongjiang Haohua will restart, which is expected to drive the capacity utilization rate of caustic soda to rise on a month - on - month basis [3]. - The profit of alumina continued to shrink. Although enterprises have not yet cut production due to cost, their purchasing intention has weakened significantly. The terminal demand in the traditional peak season is average, and non - aluminum downstream is resistant to high prices. Considering the relatively loose supply of liquid caustic soda during the pre - National Day replenishment period for downstream, the spot price of liquid caustic soda in Shandong is expected to remain under pressure [3][4]. - In the futures market, there are still expectations for anti - involution and restocking of new alumina plants. There is a game between weak reality and strong expectations. SH2601 is expected to fluctuate widely, and the main basis may remain negative. Attention should be paid to the restocking rhythm of new alumina production capacity in the future. The short - term operating range of SH2601 is expected to be around 2580 - 2680 [3][4]. 3.

1. Report's Industry Investment Rating No information provided in the content. 2. Core Views of the Report 2.1烧碱 - This week, the caustic soda futures market stopped falling and stabilized, with a significant rebound on Friday. Next week, the supply is expected to increase, and the operating rate of sample manufacturers will rise. The profit margins of domestic alumina enterprises have been continuously narrowing due to the ongoing decline in alumina prices both at home and abroad. The spot price support is weak. In the North China region, inventory has increased due to the decline in the purchase price of the main downstream in Shandong and the cautious purchasing attitude of downstream buyers. In the East China region, the supply is tight as the maintenance and production - reduction devices of enterprises have not yet resumed, and the inventory is decreasing due to the rigid demand from non - aluminum sectors. In the Shandong market, due to the approaching National Day holiday, there may be a price cut as the short - term inventory of liquid caustic soda needs time to be released, and the current supply is at a high level while the main downstream is facing difficulties in unloading [2]. 2.2 PVC - This week, the PVC futures market rebounded due to the improvement in the macro - environment. However, the supply - demand contradiction in the fundamentals is still difficult to resolve. Next week, many enterprises will end their maintenance, and the production is expected to increase. On the demand side, the improvement in the operating rate of downstream products is limited, and some have completed their inventory replenishment, so they are resistant to high prices, and the purchasing enthusiasm is average. The cost of raw material calcium carbide is on an upward trend, while the ethylene price is stable, providing bottom - line support. It is expected that PVC will stop falling and stabilize during the peak season from September to October. Attention should be paid to the performance of downstream demand [3]. 3. Summary According to Relevant Catalogs 3.1 Caustic Soda 3.1.1 Price and Market Trends - The caustic soda futures price has fluctuated due to various factors such as macro - environment, supply - demand relationship, and cost. For example, the price accelerated its decline when the macro was weak, the operating rate was high, and there were concerns about future supply. It also had rebounds under the influence of positive policies and increased demand [8]. 3.1.2 Supply - As of Thursday this week, the weekly weighted average operating rate of sample enterprises in major regions across the country was 85.44%, a decrease of 1.29 percentage points from last week's 86.73%. The operating rate in Shandong was 85.11%, a decrease of 2.24%. The inventory in the East China region increased by 0.70% from September 10th to September 17th, and the inventory in Shandong increased by 8.28% and 7.46% respectively for different sample enterprises. The overall operating rate of chlor - alkali enterprises in Shandong is still relatively high, and the downstream purchasing enthusiasm is not high, leading to an increase in inventory [27]. 3.1.3 Demand - The alumina industry, the main downstream of caustic soda, has a large number of new production capacity plans from the end of 2024 to 2025. It is estimated that the annual production capacity growth rate will be around 10%, and the annual output in 2025 will be over 88 million tons, with a production growth rate of around 6%. The new alumina projects will increase the demand for caustic soda by about 800,000 tons per year, with a concentrated demand of 150,000 tons from April to June [32]. 3.1.4 Other Related Industries - The price of bauxite is stable, the port inventory fluctuates, and the enterprise raw material inventory has increased significantly. The production of electrolytic aluminum is increasing, and the in - plant inventory is decreasing. The non - aluminum downstream industries such as printing and dyeing, textiles, and papermaking have different trends. The printing and dyeing operating rate is seasonally rising, and the textile industry is gradually entering the peak season [39][45][50]. 3.2 PVC 3.2.1 Price and Market Trends - The PVC futures price has been affected by factors such as supply - demand relationship, macro - environment, and cost. It has experienced continuous declines and rebounds. For instance, it fell when there was no positive supply - demand drive and the commodity atmosphere was poor, and rebounded when the macro - sentiment improved and there were some supply - demand contradictions [62]. 3.2.2 Supply - This week, the operating rate of the domestic PVC powder industry decreased, the weekly maintenance loss increased, and the number of temporarily shut - down devices increased. The overall operating rate of PVC powder was 75.43%, a decrease of 3.96 percentage points compared with the previous week. Among them, the operating rate of calcium - carbide - based PVC powder was 76.91%, a decrease of 3.38 percentage points, and that of ethylene - based PVC powder was 72%, a decrease of 5.2 percentage points [84]. 3.2.3 Demand - The two major downstream industries of PVC, profiles and pipes, are facing great pressure. The real - estate industry, with the goal of "reducing inventory and stabilizing prices," still has a negative impact on demand.
