Report Industry Investment Ratings No information provided in the given content. Core Views Polyolefins - PP shows a pattern of both supply and demand increasing, with reduced maintenance driving supply recovery and a slight reduction in inventory. PE shows increased supply and decreased demand, with ample imported goods and weakening demand except for agricultural films. Overall, the 01 contract still faces significant pressure [2]. Crude Oil - During the US Thanksgiving, trading was light, and the Russia - Ukraine peace talks were uncertain, leading to a slight increase in overnight oil prices. However, due to OPEC+ continuous production increase and record - high US crude oil production, the supply - demand pattern remains weak. Oil prices are expected to continue to fluctuate at a low level, with short - term focus on the $60/barrel support for Brent crude and the results of the Russia - Ukraine talks [4]. Natural Rubber - On the supply side, domestic production areas are gradually entering the production - reducing and cutting - off season, and floods in southern Thailand and Vietnam need time to recede, providing strong cost support. However, the arrival of overseas shipments is increasing seasonally, and inventory accumulation suppresses spot prices. On the demand side, overall demand is weak, and the market mainly digests channel inventory. Natural rubber is expected to enter a range - bound consolidation, with the price likely to weaken if raw material supply is smooth, and to run in the 15000 - 15500 range if supply is restricted [6]. Methanol - In the inland market, Jiutai's maintenance is over, and subsequent domestic production will continue to increase. Currently, marginal inland plants are in the red. In Iran, some plants have started gas - restricted shutdowns, improving market sentiment and strengthening the futures price and basis. It is expected to be volatile and slightly stronger in the short term [8][9]. LPG No specific overall view provided in the given content. Pure Benzene - Styrene - Pure benzene: New production capacity and plant restarts are expected, and although some plants are reducing production, supply remains loose. Downstream demand is mainly for rigid needs, and some loss - making varieties are reducing production. Port inventory is rising, and short - term prices may be dragged down by oil prices. The strategy is to short on rebounds for BZ2603 in the short term. - Styrene: With profit recovery, some plants are increasing production, but planned and unplanned shutdowns and maintenance are also increasing, limiting supply. Downstream demand support is limited, and overseas blending demand is cooling, but there are still export expectations. The short - term supply - demand outlook is improving, but the rebound space is limited. EB01 is expected to fluctuate and consolidate in the short term [13]. Ester Industry Chain - PX: Short - term supply is relatively high, and demand is weak due to PTA plant maintenance and weakening terminal demand. The short - term driver is limited, but the medium - term supply - demand outlook is tight, and it is expected to fluctuate at a high level in the short term. - PTA: Supply reduction exceeds expectations, and demand from polyester is supported. Exports are expected to increase. The supply - demand outlook is improving, and the basis is recovering. It is expected to be volatile at a high level in the short term, and the strategy is to go long on the TA month - spread at low levels. - Ethylene Glycol (EG): Polyester demand provides some support, but supply from coal - based plants is increasing, and imports are expected to be high. The port inventory has limited downward space. The strategy is to short the EG1 - 5 spread at high levels. - Short - fiber: Supply remains high, and demand is seasonally weak. The absolute price has limited drivers, and processing fees are expected to be compressed. - Bottle chips: Supply is increasing, and demand is in the off - season. The supply - demand pattern is loose, and the processing fee is expected to decline. The strategy is to short the processing fee [14]. Glass - Soda Ash - Soda Ash: Recent production has declined, and inventory has decreased, supporting the futures price. However, the medium - term oversupply problem persists, and demand is expected to remain at the previous rigid level. The supply - demand pattern is bearish, and the strategy is to wait for short - selling opportunities after rebounds. - Glass: News of production line shutdowns in Hubei has boosted the market sentiment, and the futures price has rebounded, driving better spot sales. There is still some short - term rigid demand, but long - term demand is a concern, especially with the approaching winter in the north. The market still needs capacity clearance to solve the oversupply problem. The 01 contract may face pressure near the delivery month [15]. PVC - Caustic Soda - Caustic Soda: The industry still faces supply - demand pressure. Regional supply in East China will decrease next week, but with the monthly contract signing, the spot price in East China is expected to decline if the futures price remains weakening. The demand from the main downstream, alumina, is weak, and the price is expected to be weak in the long term. - PVC: The spot market remains weak. Supply is increasing, and demand is sluggish, especially during the traditional off - season from November to January. Although the cancellation of India's BIS certification is beneficial, the expected anti - dumping tax implementation limits external demand. The supply - demand pattern is in surplus, and the price is expected to continue to be weak at the bottom [16].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - For crude oil, although the geopolitical premium has disappeared and OPEC's production increase is minimal with supply not yet surging, short - term oil prices are not advisable to be overly bearish. A low - buy and high - sell range strategy is maintained, but it is recommended to wait and see for now, waiting for a decline in OPEC exports when oil prices fall for verification [3]. - For methanol, with reduced import disturbances, prices are expected to return to be priced by its own fundamentals. Supply is high due to increased domestic production and rising imports, while demand is weak. Although the current fundamental situation is weak, short - selling is not cost - effective, and it is recommended to wait and see [5]. - For urea, domestic supply has returned with increased production, and demand is weak in the off - season. It is in a state of low valuation and weak drive, and it is recommended to wait and see [7]. - For rubber, macro disturbances may temporarily decrease, and rubber prices have stabilized in the short term. It is recommended to set stop - losses, buy on dips for short - term trading, and partially build positions for the hedge of buying RU2601 and selling RU2609 [13]. - For PVC, the supply is strong while demand is weak, and export expectations are poor. Although the valuation has declined to a low level, it is still difficult to support the weak supply - demand situation, and it is recommended to short on rallies in the medium term [14]. - For pure benzene and styrene, the cost of pure benzene is high, and the supply of benzene styrene is increasing while demand is declining. Port inventories are being depleted, and benzene styrene prices may stop falling in the short term [18]. - For polyethylene, the cost support has weakened, and although the valuation decline space is limited, high - level warehouse receipts suppress the market. It is expected to maintain a low - level oscillation [21]. - For polypropylene, the cost end is expected to have an oversupply situation, and there is high inventory pressure with weak supply and demand. It is recommended to wait and see [23]. - For PX, the load is high, and the downstream PTA has many unexpected overhauls. The inventory accumulation cycle is expected to continue, and it is recommended to wait and see [26]. - For PTA, the supply overhaul volume is high, and the de - stocking pattern continues, but the processing fee space is limited. The demand is expected to remain high, but the terminal shows signs of weakness. It is recommended to wait and see [27]. - For ethylene glycol, the supply is high, imports are increasing, and inventories are expected to accumulate in the fourth quarter.

Report Summary 1. Report Industry Investment Rating No specific industry investment rating is provided in the report. 2. Core Views - The mid - term trends of p - xylene (PX), purified terephthalic acid (PTA), and monoethylene glycol (MEG) are still weak. Before the holiday, attention should be paid to position management. For MEG, a 1 - 5 month spread reverse arbitrage is recommended [1]. - The trend intensities of PX, PTA, and MEG are all neutral (0) [3]. 3. Summary by Related Catalogs Market Data - **Futures Data**: The previous day's closing prices of PX, PTA, MEG, PF, and SC futures were 6656, 4646, 4213, 6326, and 491.3 respectively, with changes of - 18, - 32, - 33, - 46, and 0.7, and percentage changes of - 0.27%, - 0.68%, - 0.78%, - 0.72%, and 0.14% [2]. - **Month - spread Data**: The previous day's closing prices of PX1 - 5, PTA1 - 5, MEG1 - 5, PF12 - 1, and SC11 - 12 month - spreads were - 32, - 46, - 63, - 44, and - 0.8 respectively, with changes of 10, - 6, 1, 0, and 0.3 [2]. - **Spot Data**: The previous day's spot prices of PX CFR China, PTA East China, MEG, naphtha MOPJ, and Dated Brent were 814 dollars/ton, 4590 yuan/ton, 4300 yuan/ton, 608 dollars/ton, and 71.92 dollars/barrel respectively, with changes of - 3, 0, 10, - 0.5, and 1.39 [2]. - **Spot Processing Fee Data**: The previous day's spot processing fees of PX - naphtha spread, PTA processing fee, short - fiber processing fee, bottle - chip processing fee, and MOPJ naphtha - Dubai crude oil spread were 206 dollars/ton, 217.21 yuan/ton, 222.06 yuan/ton, 59.94 yuan/ton, and - 6.01 respectively, with changes of - 2.5, 19.02, - 12.24, - 29.3, and 0 [2]. Market Dynamics In 2025, on September 5, the US White House issued a presidential order, canceling the exemption from reciprocal tariffs for the tariff codes 3907.61.00 and 3907.69.00 related to polyester bottle chips, and including polyester bottle chips in the scope of reciprocal tariff collection. Recycled PET now has the same tariff system as virgin PET [2]. Views and Suggestions - **PX**: The unilateral trend may still be weak, and a 1 - 5 reverse arbitrage is recommended. The PXN position for compression should be closed with a profit. The domestic PX operating rate is 86.7% (+0.4%), and the Asian PX operating rate is 78% (-0.2%). The PTA load is 76.8% (-). The PTA processing fee has recovered to 217 yuan/ton, and PXN has dropped to 206 dollars/ton. Overseas reforming profits are low, and South Korean plants may reduce their loads in the future. Attention should be paid to the support of overseas MX blending demand for PX valuation [4]. - **PTA**: The unilateral trend may still be weak, and a 1 - 5 reverse arbitrage is recommended. Short the PTA processing fee of 01/05 contracts on rebounds. The PTA load is 76.8% (-). The polyester operating rate this week is 90.3% (-1.3%). Although there are unplanned production cuts, the supply surplus in East China is still difficult to change, and the basis is difficult to strengthen significantly. In the medium - to - long term, the inventory pressure of polyester factories is expected to rise again after the holiday [5]. - **MEG**: The unilateral trend may still be weak, and a 1 - 5 reverse arbitrage is recommended. The overall operating load of ethylene glycol in the Chinese mainland is 73.08% (down 1.85% from the previous period). Factories have announced maintenance plans for October - November. The polyester operating rate this week is 90.3% (-1.3%). The ethylene glycol supply - demand balance sheet is still strong in the near - term, and the basis is expected to be strong [6].

1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - For PTA, with the implementation of near - end TA maintenance, the start - up declined slightly, polyester load remained stable, inventory accumulated slightly, basis weakened, and spot processing fees repaired slightly. PX domestic start - up decreased, overseas devices ran smoothly, PXN weakened month - on - month, disproportionation and isomerization benefits remained stable, and the aromatics price difference between the US and Asia widened. In the future, as device restarts slow down TA de - stocking, polyester has no unexpected performance and new production is expected, the far - month inventory accumulation is expected to continue. However, the processing fees have reached a very low level and lasted for a long time, and PX supply is gradually recovering. Attention should be paid to the opportunity of expanding processing fees under potential additional maintenance [1]. - For MEG, near - end domestic oil - based EG slightly reduced its load, coal - based start - up remained stable, overseas maintenance and restarts coexisted, arrivals remained the same while shipments were dull, and port inventory accumulated slightly at the beginning of next week. Downstream stocking levels increased, the basis weakened month - on - month, and the benefit ratio shrank. Near - end new device feeding was earlier than expected, and the valuation was significantly compressed. In the future, with the increase in arrivals month - on - month and the expectation of high supply in the far - month, ports may start to gradually accumulate inventory, but the actual inventory is still not high, and the valuation may be slowly compressed. Attention should be paid to the cost support of coal - based production [1]. - For polyester staple fiber, the start - up of some devices increased, and production and sales improved month - on - month, with inventory continuing to decline. On the demand side, the start - up of the polyester yarn end remained stable, raw material stocking increased, finished product inventory decreased month - on - month, and benefits were weak. In the future, the speed of increasing the load at the polyester yarn end may slow down due to high finished product inventory, but the start - up of staple fiber remains high due to good spot benefits, and inventory pressure is limited. Processing fees are expected to fluctuate [1]. - For natural rubber, the national explicit inventory remained stable, and the price of Thai cup rubber remained stable. The strategy is to wait and see [1]. - For styrene and its downstream products, the prices of some raw materials and products decreased, and the production profits and start - up rates of some products also changed to different degrees [1]. 3. Summary by Relevant Catalogs PTA - **Device Changes**: Hengli Huizhou's 5 million - ton device reduced its load, and Fuhai Chuang's 4.5 million - ton device restarted [1]. - **Market Conditions**: The basis of the PTA main contract weakened, and the spot processing fee repaired slightly.
