1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views of the Reports Crude Oil - Monday saw a decline in international crude oil prices due to factors such as the resumption of normal operations in some Iraqi oil fields, the continuous production - increase plan of OPEC+, high - level US crude oil production, and an increase in crude oil inventory. However, the ongoing Russia - Ukraine peace talks and the expected Fed rate cut next week are likely to support prices. Short - term Brent crude is expected to trade between $60 - 65 per barrel [1]. Natural Rubber - On the supply side, the continuous decline in Thai raw material prices, the expected increase in overseas supply, the weakening of upstream cost support, and the seasonal increase in overseas shipments have led to a continuous build - up of natural rubber inventory, suppressing spot prices. On the demand side, although tire production is gradually recovering, the overall output increase is limited, and the market is mainly focused on inventory digestion. Short - term rubber prices are expected to be weak and volatile [3]. Methanol - Methanol futures fluctuated narrowly. Spot was purchased on - demand, and the basis was firm. Inland supply increased with plant restarts, but coal - and gas - based production profits were weak. Traditional downstream demand increased slightly, and winter fuel demand provided support. In ports, Iranian gas restrictions led to multiple plant shutdowns, strengthening the expectation of inventory reduction, but high overseas shipments and a large number of registered warrants kept prices weak. Attention should be paid to MTO05 [6][7]. LLDPE and PP - The operating load of polyethylene is gradually increasing, and supply is on the rise. Although upstream inventory is being depleted, it is still higher than the same period last year, and the profit from naphtha cracking is low. The supply of polypropylene is expected to increase after maintenance, and inventory depletion is accelerating, but the overall inventory level is still high. The cost of propylene is strong, compressing the profit of PP production processes. Overall, the fundamentals show a pattern of increasing supply and weak demand, with cost support and inventory pressure coexisting [11]. Pure Benzene and Styrene - For pure benzene, domestic supply is expected to remain stable, downstream cash flow has improved slightly, but demand support is limited. There will be a large number of imports arriving at ports, and port inventory is expected to continue to build up. The short - term price driver is weak, and it may follow oil prices and styrene fluctuations. For styrene, although planned and unplanned maintenance is expected to increase, the overall operating rate may rise slightly, and port inventory may continue to decline. However, due to weak cost support and seasonal weakening of terminal demand, the upside space is limited [14]. Urea - Supply pressure is continuously released as the daily production on December 8 reached a recent high. Demand is in the off - season, and downstream procurement willingness is weak. Although the inventory depletion rate of enterprises has accelerated, the overall inventory level is still high. The mismatch between supply and demand is the main reason for price decline, and short - term prices are expected to be weak and volatile [15]. Polyester Industry Chain - For PX, short - term supply is less affected, but there is an expected supply contraction in the medium - term. Demand is relatively strong, and short - term price drivers are limited, but medium - term support is strong. PTA supply is expected to decrease in November - December, and demand is relatively strong, with short - term price support. Ethylene glycol is expected to continue to decline due to high overseas supply and inventory build - up. Short - fiber supply remains high, and demand is seasonally weak, with limited price drivers. Polyester bottle - chip supply is expected to increase in December, and demand is weak, with processing fees expected to be squeezed [16]. LPG - The data shows price fluctuations in LPG futures and spot markets, as well as changes in inventory and operating rates. Overall, the market is in a state of adjustment, and attention should be paid to changes in supply and demand and international market prices [17]. Glass and Soda Ash - Soda ash production is at a high level, and it is expected to return to the inventory - build - up pattern this week. Downstream demand is shrinking, and the supply - demand pattern is bearish. Glass prices in some regions are weakening, and although there is still some short - term demand support, the medium - and long - term demand outlook is not optimistic [19]. PVC and Caustic Soda - Caustic soda industry supply is abundant, demand is weak, and prices are expected to be weak. PVC supply pressure remains high, demand is low, and although there is some export advantage, overall supply exceeds demand, and prices are expected to be weak [20]. 3.

1. Report Industry Investment Ratings - No investment ratings are provided in the reports. 2. Core Views Polyolefins - PP shows a pattern of both supply and demand increasing, with reduced maintenance driving supply recovery and inventory slightly accumulating under new - capacity pressure. PE shows increased supply and decreased demand, with abundant imported goods and weakening demand except for agricultural film. It is recommended to gradually stop losses and reduce positions on previous short positions near the previous low, and the market is expected to have limited rebound space [2]. Methanol - In the inland market, Baofeng continues to purchase externally, and Jiutai has unexpected maintenance. Iranian gas restrictions are postponed, and shipments are accelerating, putting pressure on the port methanol market. The market is trading under the "weak reality" logic, and the 01 - contract inventory contradiction cannot be resolved. It is recommended to pay attention to the marginal device operation [4]. Crude Oil - The short - term crude oil market has no clear direction. The continuous sanctions on Russia by Europe and the United States and the attacks on Russian refineries by Ukrainian drones support the oil price, but the continuous production increase of OPEC+ and the record - high US crude oil production limit the rebound space. Brent oil is expected to fluctuate between 60 - 66 dollars per barrel [7]. Natural Rubber - Supply - side factors such as cold weather in Yunnan and continuous rainy season in southern Thailand may keep raw material prices high. Demand is weak, and the market is expected to enter a range - bound consolidation. If raw material supply is smooth, there may be further downward space; otherwise, the rubber price is expected to run between 15000 - 15500 [10]. Pure Benzene and Styrene - Pure benzene supply is expected to be relatively loose, with limited demand support and high port inventory. The short - term rebound space of BZ2603 is limited, and it is recommended to wait and see. Styrene's supply - demand situation has improved in November, but the rebound space is also limited, and attention should be paid to the pressure around 6600 - 6700 for EB12 [11]. Glass and Soda Ash - Soda ash has an overall surplus pattern, with high production and inventory transfer to the middle and lower reaches. It is recommended to wait and see in the short - term and look for opportunities to short on rebounds. Glass has short - term rigid demand support but faces long - term demand contraction pressure, and it is expected to be weak in the medium - term [12]. Polyester Industry Chain - PX supply remains at a relatively high level, and the short - term demand has support, but the rebound sustainability is insufficient. PTA is expected to be in a tight balance in November and loose in the future. MEG is expected to have inventory accumulation, and short - fiber and bottle - chip also face supply - demand challenges [13]. PVC and Caustic Soda - Caustic soda has supply - demand pressure, with weak demand from the alumina industry, and the price is expected to fluctuate weakly. PVC is in an oversupply situation, with weak demand and limited upward driving force [14]. 3.

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.

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.
