Report Industry Investment Ratings No relevant content provided. Core Views Methanol Market - The current methanol market is trading on the "weak reality" logic, with the core contradiction centered on high port inventories. The 01 contract faces challenges in inventory digestion, and the weak reality pattern may continue until Iranian gas restrictions are implemented. The 05 contract is expected to see significant inventory reduction, so attention can be focused on the MTO profit shrinkage opportunity of the 05 contract [1][3]. Polyester Industry Chain - PX supply is generally stable with some plant overhauls offset by xylene supplements. Demand has some support in the short - term, but the November supply - demand is expected to be loose, and price drivers are limited. PTA may have a slight inventory build - up, and its price rebound space is restricted. Ethylene glycol is expected to have a high inventory build - up in November - December, facing upward pressure. Short - fiber supply remains high in the short - term, but demand may weaken seasonally, and its price rebound space is limited. Bottle - chip supply and demand are in a loose pattern, and it follows cost fluctuations [6]. Polyolefin Market - PP supply increase is slowing due to more unplanned overhauls, while PE supply is expected to increase as overhauls peak. Demand has improved, but overall, there is pressure from increasing supply and decreasing demand. The 01 contract has inventory pressure, while the 05 contract may offer long - term low - buying opportunities, and the month - spread is biased towards reverse arbitrage [8]. PVC and Caustic Soda Market - Caustic soda supply is expected to increase in November, with weak demand support, and its price is expected to be weakly stable. PVC supply - demand is in an oversupply situation, and its price is expected to continue to fluctuate weakly at the bottom [11]. Pure Benzene and Styrene Market - Pure benzene supply is expected to be loose in November, with limited demand support and increasing port inventories. Its price driver is weak. Styrene supply may slightly decrease in November, demand is expected to change little, and its price driver is also limited [12].

1. Report Industry Investment Ratings No information provided in the reports. 2. Core Views of the Reports Polyester Industry Chain - PX: In November, with few PX unit overhauls in Asia and China, but concentrated PTA unit overhauls, PX supply - demand is expected to be weak. PX absolute prices are expected to gradually face pressure. The strategy is to follow crude oil for unilateral trading and go short on rallies, and try to shrink the PX - SC spread [1]. - PTA: In November, there are still many PTA unit overhaul plans. With better - than - expected terminal and polyester demand in October and low polyester inventory, PTA supply - demand is expected to be slightly loose with a small inventory accumulation expectation. PTA will continue to oscillate at a low level. The strategy is to follow crude oil for unilateral trading and go short on rallies, and treat TA1 - 5 as a rolling reverse spread [1]. - Ethylene Glycol (MEG): In November, domestic supply is high, overseas shipments are concentrated, and inventory accumulation is expected to be high, putting pressure on the price. The strategy is to sell out - of - the - money call options on rallies and do a reverse spread on EG1 - 5 on rallies [1]. - Short Fiber: In November, supply is expected to remain high, demand may weaken seasonally, and cost support is limited. Short - fiber prices will gradually face pressure. The strategy is similar to PTA for PF12, and try to shrink the PF processing margin when it is above 1000 [1]. - Bottle Chips: In November, supply changes little, demand is in the off - season, and the supply - demand pattern remains loose. Bottle - chip prices will follow the cost side, and the processing margin will fluctuate with raw material costs. The strategy is similar to PTA for PR, and the main - contract processing margin is expected to fluctuate between 300 - 450 yuan/ton [1]. Chlor - Alkali Industry - Caustic Soda: In November, supply is expected to increase, demand support is weak, and prices are expected to be weakly stable. The overall trend is bearish, and it is necessary to track downstream restocking rhythm [2]. - PVC: In October, PVC prices continued to decline. In November - December, supply pressure will continue due to new capacity and high - season operation, and demand is in the off - season. Prices are expected to continue to oscillate at the bottom [2]. Methanol Industry The current market is trading the "weak reality" logic centered on high port inventory. Before the Iranian gas restriction, the weak reality will continue to be priced in. The 01 - contract inventory problem cannot be solved [3][4][5]. Pure Benzene - Styrene Industry - Pure Benzene: In November, supply is expected to be loose, demand support is limited, and although the East China port inventory decreased in October, it may increase later. Pure - benzene prices are expected to have weak driving force, but attention should be paid to unit changes [8]. - Styrene: In November, supply may slightly decrease, demand is expected to change little, and the supply - demand may be in a tight - balance state. However, high port inventory will limit price increases. The strategy is to be bearish on EB12 price rebounds [8]. Polyolefin Industry PP supply recovery has slowed down due to unplanned overhauls, while PE supply is expected to increase. Demand has recovered, but the agricultural film peak is approaching. Overall, supply will increase and demand will decrease, and there is inventory pressure on the 01 - contract. The 05 - contract may have long - term low - buying opportunities, and the monthly spread is suitable for reverse spreads [10]. 3.

Report Investment Ratings - No investment ratings are provided in the reports. Core Views Polyolefin (LLDPE & PP) - Supply: PP supply recovery is slowing due to unplanned maintenance, while PE supply is expected to increase as maintenance peaks. Attention should be paid to the potential impact of expanded international sanctions on domestic refinery loads [2]. - Demand: The demand side is warming up, with downstream开工 rising, especially in the agricultural film sector. Both LLDPE and PP inventories are decreasing [2]. - Strategy: The 01 contract still faces inventory pressure, while the 05 contract has less new capacity. Long - term low - buying opportunities for the 05 contract can be considered, and the impact of sanctions on refinery loads should be continuously monitored [2]. Methanol - Market Situation: The port methanol market is under significant pressure due to high inventories and weak demand. The inland market has deeper price drops as some external procurement stops. Overseas, multiple plants have shut down, and many MTO plants have reduced their loads due to profit issues [5]. - Market Logic: The market is trading on the "weak reality vs. strong expectation" logic, with the core contradiction being the game between high port inventories and potential supply reduction (overseas plant shutdowns/geopolitical factors) [5]. - Strategy: In the short - term, prices may continue to fluctuate. Attention should be paid to the port destocking rhythm and the implementation of overseas gas restrictions [5]. Chlor - alkali (PVC & Caustic Soda) - Price and Spread: There are various price changes in PVC and caustic soda products, including futures and spot prices, as well as spreads between different contracts [8]. - Supply and Demand: Caustic soda industry开工 is stable, while PVC开工 has decreased slightly. Downstream开工 of both products has some positive changes, and PVC inventories are increasing [8]. Pure Benzene - Styrene - Price and Spread: Prices of upstream raw materials such as crude oil, naphtha, and pure benzene have declined, while some spreads have changed. Styrene prices have also decreased, and its cash flow has improved to some extent [9][10]. - Inventory and开工: Both pure benzene and styrene inventories in Jiangsu ports have decreased, and there are changes in the开工 rates of related industries [12][13]. Polyester Industry Chain - PX: Supply is expected to contract due to unplanned maintenance or load reduction of some PX plants. Demand is supported by new PTA plants and improved terminal orders. However, the short - term rebound space of PX is limited due to weak oil price support [14]. - PTA: The spot basis is weak due to increased supply from load recovery and new capacity. The futures market is relatively firm but limited by the lack of substantial policies and weak cost - side expectations [14]. - Ethylene Glycol (MEG): Upward momentum is weakened by factors such as port conditions, plant restarts, and weak cost. The supply structure in the far - month is still weak [14]. - Short - fiber: Supply remains high, and demand has improved, leading to inventory reduction. However, the rebound space is limited due to weak downstream chasing willingness and compressed processing fees [14]. - Polyester Bottle - chip: Demand is weak in the off - season, and it is likely to enter a seasonal inventory accumulation period. The processing fee is expected to decline [14].

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views of the Reports - **Polyester Industry**: In the short term, PX, PTA, and other products are mainly in a weak shock state. The supply of PX is expected to shrink, but the overall supply - demand is still weak. PTA's basis has weakened, and the supply of ethylene glycol is abundant with a high probability of inventory accumulation. Short - fiber prices are supported by low inventory, and bottle - chips may enter a seasonal inventory accumulation channel [1]. - **Pure Benzene - Styrene Industry**: The supply - demand of pure benzene in October is expected to be loose, and the price drive is weak. The supply - demand of styrene is also expected to be loose, and the price is under pressure in the short term [2]. - **PVC and Caustic Soda Industry**: The demand for caustic soda is weakly supported in the short term but may have support in the medium - long term. The supply - demand pressure of PVC is large, and the price is weak, but the cost end provides bottom support [3]. - **Methanol Industry**: The price of methanol may continue to fluctuate. Attention should be paid to the stability of overseas device operation, the clearance efficiency of sanctioned vessels, and the actual arrival performance [4]. - **Polyolefin Industry**: The supply - demand structure of polyolefins is loose, and the upside space of the 01 contract is limited. The prices of PP and PE are under pressure [6]. 3.
