Group 1: Report Summary - The report provides a weekly analysis of the polyester industry, covering PX, PTA, MEG, and polyester products. It includes supply, demand, valuation, and inventory information, as well as trading strategies [3][4][5] Group 2: PX Analysis Valuation - Domestic PX drives up the overseas market, and the PXN spread has strengthened significantly. The gasoline market has ended the squeeze and started to build inventories. The disproportionation unit is in a loss, and the PX - MX spread remains high [15][22][23] Supply - The domestic PX operating rate is at a historical high, with an operating rate of 89.5% (+2.7%) this week. The Asian PX operating rate is 79.7% (+1.2%). Some Korean and Japanese devices have maintenance or production reduction plans [42][43] Demand - The PTA operating rate has continued to decline to 72% (-3.7%), reducing the demand for PX [3][4] Inventory - In October, the monthly inventory of PX accumulated by 100,000 tons to 4.02 million tons [65] Strategy - The upside space is limited. For cross - varieties, short PXN and long MEG short PX [3] Group 3: PTA Analysis Valuation - The inventory has continued to accumulate, but the valuation and monthly spread have risen following PX. The processing fee has remained at a low level for a long time [71][81] Supply - The PTA operating rate has declined to 72% (-3.7%). Some devices have stopped or extended the maintenance time, and the weekly output is about 1.41 million tons [4][83] Demand - The polyester device operating rate is 91.3%, with a rigid demand for PTA of 1.33 million tons. Since November, the new orders from the terminal have declined, but the rigid demand still exists [4][5] Inventory - The inventory has slightly accumulated and shifted to the delivery warehouse [106] Strategy - Operate in the range of 4500 - 4800. For cross - periods, conduct a reverse spread for 1 - 5. For cross - varieties, long MEG short PTA [4] Group 4: MEG Analysis Valuation - The monthly spread has declined, the basis has weakened, and the unilateral price trend is weak. The relative valuation has continued to decline, and the device profit is in a loss [120][124][126] Supply - The operating rate has dropped to 70.67% (-1.9%). Multiple coal - chemical devices have short - stopped, and some devices have maintenance plans in the future. The domestic weekly supply is about 405,000 tons [5][129] Demand - The polyester device operating rate remains around 91.3%, with a rigid demand for MEG of 520,000 tons. The new orders from the terminal have declined, but the rigid demand still exists [5] Inventory - The supply - demand balance sheet has improved, and the expected inventory accumulation rate has decreased [139] Strategy - Operate in the range of 3800 - 4000. For cross - periods, conduct a reverse spread for 1 - 5. For cross - varieties, long MEG short PX [5] Group 5: Polyester Analysis Production - The polyester operating rate is 91.3% (+0.8%). In 2025, the polyester production has increased by 8.5% year - on - year, and the growth rate in 2026 is expected to be flat at 5 - 6% [143][150] Export - From January to October, the total polyester export was 12 million tons, +15.2%. The exports of various polyester products have increased to varying degrees [151] Inventory - The downstream sales are sluggish, and the inventory has started to rise [152]

Core Viewpoint - The polyester industry is experiencing a stalemate in supply and demand, with PTA prices showing strength while ethylene glycol continues to weaken, leading to compressed profits for most polyester products and a predominantly weak market outlook in the short term [1] Raw Material Market Performance PTA - Price Trend: The average weekly price in East China is 4626.8 CNY/ton, up 0.90% week-on-week, indicating a strong fluctuation in spot prices [2] - Core Drivers: Supply continues to tighten due to maintenance at Sichuan Energy Investment and Yisheng Ningbo facilities, leading to an expanded inventory reduction in the balance sheet [2] - Inventory and Profit: Social inventory stands at 3.2488 million tons, down 1.21% week-on-week; average weekly profit is -281.76 CNY/ton, showing a recovery of 3.42% [3] Ethylene Glycol (MEG) - Price Trend: The average weekly price in East China is 3942.6 CNY/ton, down 0.92%, marking a new low for the year [4] - Core Drivers: The market sentiment is pessimistic, with weak rebound potential and cost support dragged down by falling crude oil prices [4] - Inventory and Profit: Inventory at East China main ports is 633,000 tons, up 2.4%; average weekly profit is -990 CNY/ton, showing a slight recovery of 2.65% [5] PX - Price Trend: The CFR China market average price is 829.2 USD/ton, up 0.53% week-on-week [6] - Core Drivers: Low operating rates at Korean plants and low disproportionation benefits support the increase in PXN price spreads [6] - Supply and Demand: Domestic production is 748,100 tons, down 0.41%; domestic consumption is 939,400 tons, down 4.38%, indicating a positive supply-demand shift [7] Polyester Industry Core Data Overall Supply - Weekly production is 1.5538 million tons, up 0.27% week-on-week; average capacity utilization rate is 87.59%, slightly up by 0.07% [8] - Driving Factors: The restart of the Jinqiao facility and the commissioning of new facilities by Yuxin and Youshun, along with the delayed maintenance of Dawo, contribute to a slight increase in supply [8] Major Product Performance - **Polyester Filament**: POY 150D/48F average price is 6620 CNY/ton, up 0.61%; profit is 143.32 CNY/ton, up 13.34%; inventory is 14.1 days, up 15.57% [10] - **Polyester Staple Fiber**: Average price is 6287 CNY/ton, down 0.38%; profit is -189.69 CNY/ton, down 33.07%; inventory is 13.88 days, up 1.31% [10] - **Polyester Bottle Chips**: Average price is 5741 CNY/ton, down 0.03%; profit is -154.19 CNY/ton, down 19.63%; supply-demand remains stagnant [10] - **Polyester Chips**: Average price is 5575 CNY/ton, down 0.07%; profit is -101.62 CNY/ton, down 36.31%; inventory is 13.49 days, up 6.14% [10] End Demand and Weaving Market - Weaving Operating Rate: The comprehensive operating rate in the Jiangsu and Zhejiang regions is 67.69%, down 0.30% [11] - Orders and Inventory: The average order days for end weaving is 13.54 days, down 0.95 days; finished product inventory for long fiber cloth is 22.85 days, up 0.68 days [11] - Demand Characteristics: Winter orders are nearing completion, with new orders showing weak growth; spring orders are starting but lack substantial support, leading to a weaker market atmosphere compared to the same period last month [11] Market Outlook for Next Week Raw Material Side - PTA: Supply continues to shrink, with inventory reduction ongoing; however, insufficient end demand is expected to keep prices in the range of 4500-4650 CNY/ton [12] - Ethylene Glycol: Total supply is expected to increase, with weakened cost support; spot prices are projected to run between 3800-3900 CNY/ton [13] - PX: Supply is expected to rise, and with potential declines in crude oil prices, the market is anticipated to remain weak, with CFR China prices around 828 USD/ton [14] Polyester Side - Supply: New facilities are expected to continue releasing incremental output, with weekly polyester production projected to slightly increase to around 1.56 million tons [15] - Demand: End weaving demand is unlikely to see substantial improvement, with new orders not connecting well, leading companies to focus on inventory digestion [15] - Price Trend: Most polyester products lack cost support, and weak demand is expected to lead to a predominantly weak market trend, with prices for polyester filament, bottle chips, and chips likely to decline slightly [15] Key Focus Areas 1. Progress and restart plans for PTA facility maintenance [16] 2. Impact of international crude oil price fluctuations on cost [16] 3. Timing of spring order launches and changes in weaving operating rates [17]

1. Report Industry Investment Rating - All commodities in the report, including crude oil, fuel oil, asphalt, polyester, rubber, methanol, polyolefins, and polyvinyl chloride, are rated as "oscillating" [1][3][5][6][8] 2. Core Views of the Report - **Crude Oil**: On Thursday, oil prices closed down. The macro - non - farm data was below expectations, pressuring the market. European ARA hub inventory data showed mixed trends. The market is fragile and sensitive to negatives, and oil prices are expected to continue oscillating [1] - **Fuel Oil**: Futures prices fell on Thursday. Singapore's October sales data showed growth and decline in different types. In November, sufficient inventory will suppress the low - sulfur market, while the high - sulfur market has relatively healthy downstream demand, and prices are expected to be weak [3] - **Asphalt**: The futures price rose on Thursday. Supply may decline slightly in the short - term due to profit reduction, and downstream demand is limited due to weather, so the price is treated with a bearish view [3] - **Polyester**: Futures prices of related products fell. Some devices had maintenance and restart operations. With the improvement of the PTA fundamentals, its price is expected to oscillate strongly, while the ethylene glycol has short - term supply improvement but medium - term inventory pressure, and its price will adjust widely [5] - **Rubber**: Futures prices fell on Thursday. The supply pressure increases while the downstream demand is weak externally, but winter storage demand supports the price, so the price is expected to oscillate [6] - **Methanol**: Supply has returned to a high level recently, but Iranian devices may stop in the future, and port inventory is expected to decline from December to January, so the price is expected to oscillate at the bottom [6] - **Polyolefins**: The market is gradually shifting to a situation of strong supply and weak demand, but the low valuation may prompt downstream actions, and the price is expected to oscillate weakly at the bottom [6][8] - **Polyvinyl Chloride**: Market prices in different regions decreased. Supply remains high, and demand will decline due to the slowdown of real - estate construction, so the price is expected to oscillate weakly [8] 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: WTI 12 - month contract closed down $0.3 to $59.14/barrel, Brent 1 - month contract closed down $0.13 to $63.38/barrel, and SC2512 closed at 456.7 yuan/barrel, down 1.7 yuan/barrel.

Report Industry Investment Ratings No relevant content provided. Core Views of the Reports Polyolefins - PP shows a pattern of both supply and demand increase, with reduced maintenance leading to increased supply and slight inventory accumulation under new capacity pressure. PE shows increased supply and decreased demand, with abundant imported goods and weak demand except for agricultural film. The cost side has fluctuating crude oil and strong coal, and PDH profits continue to weaken [2]. Crude Oil - The US proposed a new plan to restart the Russia - Ukraine peace negotiation, causing geopolitical premiums to decline and oil prices to fall. OPEC+ is continuously increasing production, and US crude oil production is at a new high, resulting in a weak supply - demand pattern and significant pressure on oil prices. Short - term Brent crude is expected to find support at $60 per barrel [3]. Natural Rubber - Supply: Domestic production areas are entering the production - reducing and cutting - off season, and rainfall in overseas areas keeps raw material prices high. However, the arrival of overseas ships is increasing seasonally, and inventory accumulation suppresses spot prices. Demand: Overall demand is weak, and the market mainly focuses on digesting channel inventory. It is expected that the natural rubber market will enter a range - bound consolidation [5]. Glass and Soda Ash - Soda Ash: The market is in an overall surplus situation. Supply is high, and downstream demand is mainly based on rigid needs. The supply - demand pattern is still bearish, and it is recommended to wait for rebounds to short [7]. - Glass: Recently, prices have been falling, and low prices have driven better sales. However, there are still production line restarts in the future, which will increase supply pressure. In the short term, there is some rigid demand support, but in the long term, demand will shrink, and prices will be under pressure [7]. PVC and Caustic Soda - Caustic Soda: The supply - demand situation is under pressure. The main downstream, alumina, has reduced purchasing enthusiasm. Although there is some supply reduction in the East China region, the long - term supply - demand pressure remains large, and prices are expected to be weak [8]. - PVC: The spot market is in a weak and volatile state. Supply is still at a high level, and demand is in the off - season. The export situation is not optimistic, and the supply - demand surplus pattern continues, with prices expected to remain at the bottom [8]. Polyester Industry Chain - PX: Asian and domestic PX loads have decreased, but supply remains high. Demand is weak, and although there are some supporting factors, the rebound space is limited, and it is expected to be in a high - level shock in the short term [9]. - PTA: After the maintenance of some devices, the basis has strengthened slightly. The supply - demand situation is expected to be relatively balanced in November and more relaxed from December to the first quarter. The rebound space is limited, and it is expected to be in a high - level shock in the short term [9]. - Ethylene Glycol: Domestic supply remains high, and overseas shipments will be concentrated in November, leading to inventory accumulation and a weak basis. It is under pressure above, and corresponding option and spread strategies are recommended [9]. - Short - fiber: Supply remains high, and demand is seasonally weak. The absolute price drive is limited, and processing fees are expected to be compressed [9]. - Bottle - grade PET: Supply changes little, and demand support is insufficient. The supply - demand pattern is loose, and the social inventory is likely to enter the seasonal accumulation period. The processing fee will follow the raw material cost [9]. Methanol - In the inland market, production will continue to increase, and marginal devices are in a loss state. In the port market, Iranian gas restrictions are postponed, and shipments are accelerating, resulting in high inventory and weak prices. The core contradiction is high port inventory, and the "weak reality" logic will continue [10]. Pure Benzene and Styrene - Pure Benzene: Although there are maintenance expectations for some devices, imports are expected to be high, and overall supply may be relatively loose. Demand support is limited, and port inventory is accumulating. The supply pressure is large, and the short - term BZ2603 contract is recommended to be observed [13]. - Styrene: The supply - demand situation has improved, with export expectations and falling port inventory. However, profit recovery may lead to delayed maintenance and new device trials, and downstream EPS demand is expected to weaken, so the upside space is limited [13]. Summaries According to Related Catalogs Polyolefins - **Prices and Spreads**: L2601, L2605, PP2601, and PP2605 have different price changes, and there are also changes in spreads such as L15, PP15, and LP01. Spot prices of PP and LLDPE in some regions have declined [2]. - **Inventory and开工率**: PE and PP enterprise and social inventories have decreased to varying degrees. PE and PP device and downstream weighted开工率 also show different trends [2]. Crude Oil - **Prices and Spreads**: Brent, WTI, and SC crude oil prices have declined, and there are also changes in spreads such as Brent - WTI and SC - Brent.
