1. Report Industry Investment Rating No information provided in the report. 2. Core Viewpoints of the Report - PTA: The PTA futures oscillated and declined yesterday, with a general negotiation atmosphere in the spot market and a slightly stronger spot basis. The processing margin remains at a low level. It is expected that the PTA spot price will mainly oscillate following the cost side in the short term, and the spot basis will fluctuate within a range. Attention should be paid to the changes in the equipment [5]. - MEG: On Tuesday, the price center of ethylene glycol oscillated and declined, and the spot basis continued to decline. In the long - term, there is still a pressure of inventory accumulation for ethylene glycol. In the near - term, it has improved due to a reduction in some supplies. The short - term price center of ethylene glycol is expected to operate weakly, and there is continuous upward pressure. Attention should be paid to the outflow speed of warehouse receipts in northern Jiangsu [7]. 3. Summary According to the Table of Contents 3.1.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints 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 should not be overly bearish. A low - buy and high - sell range strategy is maintained, but it's advisable to wait and see for now to verify OPEC's export price - support intention through a decline in exports when prices fall [3]. - For methanol, high port inventories are suppressing prices. Overseas production remains high, and the supply pressure persists while demand is weak. It's expected that inventories will be hard to reduce in the short term, and prices may decline further. Given the current significant and rapid drop, it's recommended to wait and see [6]. - For urea, the market is sensitive to positive news due to large internal - external price differences and low domestic prices. Domestic demand lacks support, and supply is high. New export policies have improved the market atmosphere, and inventories are being reduced. It's expected that the downside space is limited, and the market will mainly bottom out through oscillations [9]. - For natural rubber, a short - term long - bias trading strategy is recommended, and a partial position can be established for the hedge of buying RU2601 and selling RU2609 [12]. - For PVC, the fundamental situation is poor. Supply is strong, demand is weak, and export expectations are turning negative. There is a continuous inventory build - up pressure. It's advisable to consider short - selling on rallies in the medium term [14]. - For pure benzene and styrene, the BZN spread has room for upward correction. The supply of pure benzene is relatively abundant, and the production of styrene is increasing. Styrene port inventories are decreasing significantly, and prices may stop falling in stages [17]. - For polyethylene, the crude oil price may have bottomed out, and the downward valuation space of PE is limited. However, a high number of warehouse receipts is suppressing the market. Overall inventories are being reduced from a high level, and prices may remain in a low - level oscillation [20]. - For polypropylene, the cost - end supply surplus may expand. Supply pressure is high, and demand is weak. Overall inventory pressure is high, and the market may be supported when the supply - surplus situation at the cost end changes in the first quarter of 2026 [23]. - For PX, it's expected to have a slight inventory build - up in November, but there is support from aromatics blending for gasoline and the long - term supply - demand structure. There are opportunities for valuation to rise in the medium term [26]. - For PTA, there will be continuous inventory build - up in November due to new device launches, and processing fees will be under pressure. The polyester load is unlikely to increase significantly. There are opportunities for PTA to strengthen driven by an increase in PXN in the medium term [28][29]. - For ethylene glycol, there will be continuous inventory build - up in the fourth quarter. Valuation is relatively low and may be further compressed. It's recommended to short - sell on rallies [31]. 3.

Report Industry Investment Ratings No relevant content provided. Core Views Polyolefins - The polyolefin market is under pressure, with a divergence in the fundamentals of PP and PE. PP shows a dual increase in supply and demand, but there is a slight inventory build - up this week under the pressure of new production capacity. PE has weak supply and demand, and although there is inventory reduction this week, port inventory remains high. The cost side is mixed, with high inventory and cost support in a continuous game [2]. Glass and Soda Ash - For soda ash, the overall supply - demand pattern is still bearish. Short - term observation is recommended, and opportunities to short on rebounds can be awaited later.

Report Industry Investment Rating No relevant information provided. Core Viewpoints of the Report - For crude oil, although the geopolitical premium has dissipated and OPEC's production increase is minimal with supply not yet surging, oil prices should not be overly shorted in the short - term. A low - buy and high - sell range strategy is maintained, but it's advisable to wait and see for now to verify OPEC's export price - support intention [3]. - For methanol, port prices are falling rapidly, the supply - demand pattern is "supply increasing and demand weakening", inventory is difficult to deplete. With the unfulfilled expectation of overseas winter production cuts, there is a risk of further decline in the future. It's recommended to wait and see [6]. - For urea, supply and demand have both increased, the market is in a relatively loose pattern, and there is limited upward momentum. Given the low absolute price, the downside space is also limited. It's recommended to wait and see [9]. - For rubber, the price shows signs of stabilization. Short - term long trading with quick entry and exit is suggested, and partial position building for the hedge strategy of buying RU2601 and selling RU2609 is recommended [13]. - For PVC, the enterprise's comprehensive profit is at a low level, supply is strong and demand is weak, export expectations are weak, and there is a risk of inventory accumulation. It's advisable to look for shorting opportunities on rallies in the medium - term [14][15]. - For pure benzene and styrene, the BZN spread is at a relatively low level and has room for upward repair.

Report Industry Investment Ratings No relevant content provided. Core Views of the Report PVC and Caustic Soda - The caustic soda market has weak demand support in the short - term due to high supply, low downstream alumina prices, and shrinking industry profits. However, there may be support in the medium - to long - term as the demand procurement cycle approaches and there may be concentrated stocking in the fourth quarter and more alumina production in the first quarter of next year [1]. - The PVC market is expected to continue the logic of a lackluster peak season. The supply has returned to a high level as some maintenance enterprises resumed production this week, while domestic downstream demand remains low, and the cost side provides only bottom - line support [1]. Polyester Industry - For PX, the short - term supply is stable with some plant overhauls offset by toluene and xylene supplements. The demand has strengthened slightly but the overall expectation is weak, and the cost support from oil prices is limited [2]. - For PTA, the spot basis is weak due to increased device loads and new production, and the expected rebound is under pressure [2]. - For ethylene glycol, the upward momentum is weakening due to port inventory changes, refinery maintenance, and falling oil prices. The far - month supply - demand structure is weak, and there is significant upward pressure [2]. - For short - fiber, the supply is high, the demand has improved marginally but the downstream's willingness to chase price increases is low. The cost support is limited, and the price is expected to face pressure in the rebound, although it is relatively stronger than raw materials due to low inventory [2]. - For bottle - chips, the demand is in the traditional off - season, and it is likely to enter a seasonal inventory accumulation period. The price mainly follows the cost side, and the processing fee is expected to fluctuate within a certain range [2]. Pure Benzene and Styrene - The supply of pure benzene in China is abundant with device restarts and new capacity expectations. The demand support is limited as most downstream products are in the red and some secondary - downstream inventories are high. The overall supply - demand expectation is loose, and the price drive is limited [5]. - Styrene is under pressure from inventory and industry profits. Although there are more planned and unplanned device shutdowns, new production from some plants maintains supply pressure. The demand support is limited as downstream industries mainly make rigid purchases due to high finished - product inventories. The supply - demand pattern remains weak, and the rebound is expected to face pressure [5]. Methanol - The port methanol market is under significant pressure due to high inventory and weak demand, resulting in a decline in both price and basis. The inland market has weak sales as producers offer discounts and downstream buyers are hesitant. The demand side is weak as multiple MTO units reduce loads and plan more maintenance. The short - term price is expected to continue to decline, and attention should be paid to port inventory reduction and overseas gas restriction expectations [7][8]. Polyolefins - For PP, the supply recovery is slow due to more unplanned maintenance. For PE, the maintenance is peaking, and the supply is expected to increase. The demand side has improved with rising downstream operating rates, especially in the agricultural film sector. Both inventories are decreasing. The 01 contract still has inventory pressure, while the 05 contract may offer long - term low - buying opportunities [10].
