1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - For PTA, with some proximal TA devices under maintenance, the start - up rate decreased, polyester load increased, inventory was depleted, basis strengthened slightly, and spot processing fees improved. PX domestic start - up increased, overseas devices reduced load, PXN strengthened, and cost - end PX had a good pattern. Attention should be paid to the opportunities of positive spreads at low prices and expanding processing fees [2]. - For MEG, with domestic oil - based production increasing load and coal - based production having some maintenance and load reduction, overall start - up declined. With supply load reduction and high polyester start - up, the inventory accumulation speed is expected to slow down. There are opportunities for short - term selling of put options, but the long - term pattern is expected to be weak [2]. - For polyester staple fiber, the short - term inventory pressure is limited due to high export growth, but the pattern may weaken in the long - term as the downstream enters the off - season and new devices are about to be put into production. Attention should be paid to the warehouse receipt situation [2]. - For natural rubber and 20 - grade rubber, with stable national explicit inventory and stable Thai cup - lump rubber prices affected by rainfall, the strategy is to wait and see [5]. 3.

1. Report Industry Investment Rating No related content provided. 2. Core Views of the Report - For crude oil, although the geopolitical premium has dissipated and OPEC's production increase is minimal with supply not yet surging, short - term oil prices should not be overly bearish. A low - buying and high - selling range strategy is maintained, but it's advisable to wait and see for now to verify OPEC's export price - supporting willingness [2]. - For methanol, high port inventories suppress prices. Overseas production remains high, and with high coal prices squeezing profit margins, corporate production has slightly declined. Demand is weak, so prices may fall further, and it's recommended to wait and see [3]. - For urea, the market is sensitive to positive news due to large domestic - foreign price differentials and low domestic prices. Domestic demand is weak, and supply is high. New export policies may improve the situation, and prices are expected to bottom out with limited downside [6]. - For rubber, a short - term long - biased trading strategy is recommended, and partial hedging positions can be established by buying RU2601 and selling RU2609 [11]. - For PVC, the supply - demand situation is poor with high supply and weak demand. Export expectations are weakening, and it's advisable to consider short - selling on price rallies in the medium term [14][15]. - For pure benzene and styrene, the supply of styrene is under pressure, but the BZN spread has room for upward repair. Port inventories are decreasing, and styrene prices may stop falling temporarily [18]. - For polyethylene, although the price may have bottomed out, high warehouse receipt volumes suppress the market. With seasonal demand picking up, prices may remain range - bound at a low level [21]. - For polypropylene, there is high supply pressure and weak demand. High inventory levels persist, and the market may be supported when the supply - surplus situation changes in Q1 next year [24]. - For PX, it is expected to see a slight inventory build - up in November, but there is support from aromatics blending and long - term supply - demand. There may be opportunities for valuation to rise in the medium term [25]. - For PTA, supply is increasing, and demand is facing challenges. However, there may be opportunities for PTA to strengthen driven by an increase in PXN in the medium term [27][28]. - For ethylene glycol, domestic supply is high, imports are rising, and inventories are building up. It's recommended to short - sell on price rallies [30]. 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 Rating - Not provided in the report Core Viewpoints - For lead, due to high lead prices, downstream purchasing enthusiasm has weakened. Meanwhile, refinery profits are good, and production has recovered, improving the supply shortage. Thus, the lead price is under pressure above [1]. - For zinc, overseas structural risks have weakened, and there is insufficient momentum for the zinc price to continue rising. Attention should be paid to trading opportunities brought by the recovery of the Shanghai-London ratio. In the medium term, the mine end will tighten in the fourth quarter [1].

The supply of refineries is expected to increase, and the export window of zinc ingots is expected to open [1]. - On the demand side, there is no significant improvement [1]. Trading Strategy - Wait for the opportunity to buy on dips after the callback [1]. Other Information - On November 11, the China Zinc Smelters Purchasing Team (CZSPT) held a quarterly meeting in Kunming, Yunnan, and released the guidance price range for the import zinc concentrate procurement US dollar processing fee before the end of the first quarter of 2026: 105 US dollars (average) - 120 US dollars (average) per dry ton [1]. - On November 11, the [LME0 - 3 zinc] was at a premium of $117.04 per ton, and the open interest was 219,916 lots, a decrease of 750 lots [1]. - On November 11, the [LME0 - 3 lead] was at a discount of $20.89 per ton, and the open interest was 153,641 lots, an increase of 2,117 lots [1].

Report Industry Investment Ratings - PX: Unilateral trend is moderately strong in the medium term [1] - PTA: Supply pressure persists, high - level volatile market, backwardation in calendar spreads [1] - MEG: Supply pressure remains high, trend is weak [1] Core Views - PX: The unilateral trend is strong. It is recommended to go long on PX and short on PTA/MEG. Despite the restart of some devices and the high operating rate, the cost support and demand factors make the unilateral strong pattern clear [5]. - PTA: With positive demand feedback and cost support, it should be regarded as unilaterally strong. Although the inventory accumulation in November narrows, the supply is still in excess after some device overhauls end, and the processing fee may continue to be under pressure [6]. - MEG: It is short - term oscillating weakly. The supply pressure persists, and it is recommended to maintain the backwardation operation in calendar spreads. Although the supply pressure eases slightly in the short term, it remains in the long term [6]. Summary by Related Catalogs Market Dynamics - A 300,000 - ton/year polyester bottle - chip device in the southwest has been shut down for maintenance since early November, with a total of 600,000 tons of production shut down at the factory [3]. - The price increase in the previous trading day was mainly driven by increased stock market activity. The sudden increase in market activity may be due to the entry of external funds [3]. - The PX market is currently quite stable fundamentally, and there is no obvious weakness in the short term. The main support for PX comes from China's higher PTA production capacity, especially from new factories launched this year [3]. - Formosa Chemicals & Fiber Corp. restarted its 720,000 - ton/year PX production line in Mailiao on November 4 after completing the planned turnaround, and has been operating at about 70% capacity since then. A 350,000 - ton/year production line has been shut down since early April for planned turnaround [5].

Yulong Petrochemical was sanctioned, resulting in weak MX prices. Although the short - process profit is strong, the operating rate has not actually recovered [5]. - Demand: Some PTA devices were shut down or had reduced loads, and the PTA load declined. The stock prices of polyester leaders rose sharply, but the actual probability of production reduction is low [5]. PTA - Supply: Some factories without supporting facilities reduced their loads, and the inventory accumulation in November narrowed. After the overhaul of some devices such as Xin凤鸣 ended, the supply was still in excess [6]. - Demand: The polyester load remained high (91.5% in November), and the rigid demand for PTA was acceptable [6]. MEG - Supply: The overall operating rate of MEG declined this week, with multiple devices shut down or reducing loads. However, Zhenhai Refining & Chemical's 800,000 - ton device is about to restart, and the long - term supply pressure remains due to concentrated imports [6]. - Demand: Downstream weaving orders weakened locally, and the operating rate declined. However, the polyester load remained high in the short term, providing some demand support [6]. Valuation and Strategy - PX: The PXN spread has risen to a high level, and producers can hedge at high prices. It is recommended to go long on PX and short on PTA/MEG [5]. - PTA: The processing fee of the 01 contract has reached a new low of 219 Yuan/ton, and the spot processing fee is 173 Yuan/ton. The processing fee may continue to be under pressure [6]. - MEG: It is recommended to maintain the backwardation operation in calendar spreads [6].

1. Report Industry Investment Rating The report does not explicitly mention the industry investment rating. 2. Core Viewpoints of the Report - The energy and chemical industry is expected to continue its oscillatory consolidation. Crude oil should be treated with an oscillatory mindset. PX is in a strong position, and the short - term price is expected to be oscillatory and slightly bullish. PTA's supply - demand pattern shows an improvement expectation, and the price is expected to be supported [3][14]. - Most products in the energy and chemical sector are expected to oscillate, with some showing a slightly bullish or bearish tendency in the short - term, depending on factors such as supply - demand relationships, cost changes, and market sentiment [3]. 3. Summary According to Relevant Catalogs 3.1 Market Overview - On November 6, 2025, the Chinese A - share market rose, and the commodity market sentiment generally improved. PX and PTA in the energy and chemical sector performed well, with PX rising more than PTA, and TA's processing fee per ton dropping to 120 yuan/ton. The rise of aromatics is related to the high cracking spread of global gasoline, and there has been arbitrage from Asian blending products to the Americas recently. The downstream demand for polyester remains healthy, and the loom operating rate has increased week - on - week [2]. 3.2 Product - by - Product Analysis 3.2.1 Crude Oil - **Viewpoint**: Supply pressure persists, geopolitical risks remain, and the price is expected to oscillate. - **Main Logic**: Saudi Arabia has lowered the official selling price for Asia, corresponding to the downward shift of the Middle - East oil premium center in the past month. Russian refineries have been attacked, and the US refined oil inventory has decreased smoothly since October. The overseas gasoline and diesel markets remain strong, and the reduction of refined oil inventory pressure and the strong cracking spread support the crude oil demand. However, the continuous inventory build - up in reality is difficult to change, so the price oscillates [9]. 3.2.2 Asphalt - **Viewpoint**: The asphalt futures price may test the 3200 yuan/ton resistance level again. - **Main Logic**: OPEC+ is expected to continue increasing production in December, the Israel - Palestine conflict has ended, and the situation between the US and Venezuela is under control. The asphalt futures price has fallen below the important support level of 3200 yuan/ton, which may turn into a resistance level. The asphalt - fuel oil spread has fallen below 400 yuan/ton, the production schedule in November has decreased significantly, but the demand has entered the off - season. The supply shortage problem has been resolved, and the driving force for the high premium of asphalt has weakened. The pricing weight of asphalt futures has returned to Shandong, and the inventory build - up pressure is still large [11]. 3.2.3 High - Sulfur Fuel Oil - **Viewpoint**: The fuel oil is expected to oscillate weakly. - **Main Logic**: OPEC+ is expected to continue increasing production in December, the Israel - Palestine conflict has ended, but the premium on Russian products in Europe and the US still exists. The fuel oil supply in the Asia - Pacific region in November is expected to decrease due to the decline in Russian exports. However, the refinery processing demand is weak, and the fuel oil demand is still weak as it has entered the off - season [11]. 3.2.4 Low - Sulfur Fuel Oil - **Viewpoint**: The refined oil market is strong, and low - sulfur fuel oil may run strongly. - **Main Logic**: Low - sulfur fuel oil follows the weak oscillation of crude oil, and the 3500 yuan/ton resistance level is effective in the short - term. The main product attribute of low - sulfur fuel oil is strong, and the decline in Russian refined oil exports has driven the rebound of the gasoline and diesel cracking spread, supporting low - sulfur fuel oil. However, it faces negative factors such as the decline in shipping demand, green energy substitution, and high - sulfur substitution. The valuation of low - sulfur fuel oil is low, and it is expected to follow the movement of crude oil [13]. 3.2.5 Methanol - **Viewpoint**: The 2100 yuan/ton integer level provides some support, and methanol is expected to oscillate. - **Main Logic**: The methanol futures price oscillated on November 6. The domestic methanol factory operating rate remains high, resulting in sufficient supply. The port inventory is relatively high, which still suppresses the price in the short - term. However, considering the possible disturbances in Iran in winter, methanol still has long - buying value and should be treated with an oscillatory view in the short - term [28]. 3.2.6 Urea - **Viewpoint**: The export information has been confirmed, and urea is expected to oscillate strongly in the short - term. - **Main Logic**: On November 6, the supply - demand pattern of urea remained loose. Although the supply has returned to a high level after the end of plant maintenance, the demand is weak due to the end of winter wheat sowing. The high inventory pressure still exists, but the coal cost provides strong support. Combined with the speculation about export information in the market, urea is expected to oscillate strongly [28]. 3.2.7 Ethylene Glycol (EG) - **Viewpoint**: Supply and demand are under pressure, and the rebound height is limited under the fermentation of market sentiment. - **Main Logic**: The polyester chain products have strengthened, but EG's own supply - demand is weak, and the port inventory has continued to increase this week. The overall price elasticity of EG will be significantly suppressed in the medium - term. Although the factory operating rate of EG has decreased this week, providing some support to the price, the long - term inventory build - up pressure is large, and the rebound height is limited [20][21]. 3.2.8 PX - **Viewpoint**: PX is leading the polyester chain strongly, and the short - term market sentiment is enthusiastic. - **Main Logic**: The cost change is limited. There are rumors of production cuts and PX factory maintenance in the market, driving PX and PTA prices up. PX has been in a strong position in 2025, with continuous inventory reduction and tight spot liquidity. The supply of PX is expected to be tight in the first half of next year, and the positive growth of downstream demand supports PX demand to some extent [14]. 3.2.9 PTA - **Viewpoint**: After the meeting, PTA plants have stopped production in batches, and the market sentiment continues to ferment. - **Main Logic**: Affected by market news, the PTA futures price has strengthened significantly. Although it is difficult for enterprises to reach a coordinated production - cut agreement, there are many planned plant disturbances in November. The supply - demand pattern of PTA is expected to improve, and the downward compression space of the PTA processing spread is limited, but the upward space depends on whether there is more than expected production cut [14]. 3.2.10 Short - Fiber - **Viewpoint**: Caught between rising costs and falling demand expectations, the processing fee is passively compressed. - **Main Logic**: The price of upstream raw materials has risen due to capital speculation, and short - fiber has followed the cost increase but with a smaller increase, resulting in a passive compression of the processing fee. Although the downstream procurement has increased in the afternoon under the influence of market sentiment, the overall sales this week have been weak, and short - fiber has continued to accumulate inventory [22][23]. 3.2.11 Bottle - Chip - **Viewpoint**: It follows the rise of raw materials passively. - **Main Logic**: The upstream raw material futures have risen, driving some polyester bottle - chip factories to raise their prices. The market trading atmosphere is okay, and the processing fee is within a stable range [24][25]. 3.2.12 Polypropylene (PP) - **Viewpoint**: As the price drops, the trading volume increases, and PP is expected to oscillate. - **Main Logic**: The downstream trading volume has increased as the price drops. The price of crude oil oscillates, and OPEC+ has shown a cautious attitude towards increasing production. PP's own fundamental support is limited. As the peak season fades, the upstream and mid - stream still have the intention to reduce inventory at high prices, and the production pressure is large due to the decrease in maintenance and the increase in production capacity [31][32]. 3.2.13 Linear Low - Density Polyethylene (LLDPE) - **Viewpoint**: The downstream trading volume has increased, and LLDPE is expected to oscillate. - **Main Logic**: The LLDPE futures price oscillates. The price of crude oil oscillates, and OPEC+ has shown a cautious attitude towards increasing production. LLDPE's own fundamental support is limited. As the peak season fades, the upstream and mid - stream still have the intention to reduce inventory at high prices, and the production pressure is large due to the decrease in maintenance and the increase in production capacity [30]. 3.2.14 PVC - **Viewpoint**: The market sentiment has cooled down, and PVC is expected to oscillate weakly. - **Main Logic**: At the macro - level, the macro - disturbances in November have subsided. At the micro - level, the PVC fundamentals are under pressure, with stable costs. The upstream maintenance has ended in early November, and PVC production will increase. The downstream operating rate has recovered, but only the low - price procurement volume has increased. The PVC export order signing has weakened this week, and the anti - dumping measure suppresses the export expectation [34]. 3.2.15 Caustic Soda - **Viewpoint**: With low valuation and weak expectations, caustic soda is expected to oscillate. - **Main Logic**: At the macro - level, the macro - disturbances in November have subsided. At the micro - level, the fundamentals of caustic soda have improved this week, but the driving force for continuous improvement is limited. The alumina production capacity has decreased, the demand for caustic soda from Weiqiao is still high, the new alumina project in Guangxi in the first quarter of 2026 will boost the demand for caustic soda, the non - aluminum operating rate is stable, and the replenishment intention is not high. The maintenance of caustic soda plants will end in early November, and the production will increase month - on - month [35]. 3.3 Data Monitoring - **Inter - period Spreads**: The inter - period spreads of various products such as Brent, Dubai, PX, PTA, etc. have changed to different extents. For example, the 1 - 5 month spread of PX has increased by 22 yuan/ton [37]. - **Basis and Warehouse Receipts**: The basis and warehouse receipts of different products also show different changes. For example, the basis of asphalt has increased by 17 yuan/ton, and the warehouse receipt is 7690 [38]. - **Inter - product Spreads**: The spreads between different products, such as 1 - month PP - 3MA, 1 - month TA - EG, etc., have also changed. For example, the 1 - month TA - EG spread has increased by 78 yuan/ton [40].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The energy and chemical industry will continue to consolidate in a range. Attention should be paid to when the high inventory of liquid chemicals starts to decline. The supply pressure of crude oil persists, and geopolitical risks still exist. The overall chemical industry continues its weak and volatile pattern, with methanol rebounding during the day. The supply of PTA is limited in the short - term, and the processing fee of short - fiber is expected to be compressed. Energy and chemical products generally show a pattern of range - bound movement [2][3][4]. 3. Summary by Relevant Catalogs 3.1 Market Outlook - **Crude Oil**: Supply pressure continues, and geopolitical risks remain. The EIA data shows that the US crude oil inventory increased last week, the refinery operating rate decreased month - on - month, and gasoline and diesel continued to destock. The overseas refined oil inventory pressure has eased, and the crack spread is strong, which still provides phased support for the demand side of crude oil. However, the reality of continuous inventory accumulation is difficult to change, and the price is expected to fluctuate [4][8]. - **Asphalt**: The asphalt futures price may test the 3200 pressure level again. The OPEC + group will continue to increase production in December, and after the end of the Palestine - Israel conflict, the crude oil price has declined. The supply tension problem has been resolved, and the over - valuation premium of asphalt has begun to decline [4][9]. - **High - Sulfur Fuel Oil**: The fuel oil is in a weak and volatile state. The supply of fuel oil in the Asia - Pacific region is expected to decline in November due to the decrease in Russian exports. However, the demand for fuel oil is still weak, and attention should be paid to the development of the Russia - Ukraine conflict [4][9]. - **Low - Sulfur Fuel Oil**: It follows the crude oil and fluctuates weakly. It is affected by the decline in Russian refined oil exports, but it is also facing negative factors such as the decline in shipping demand, green energy substitution, and high - sulfur substitution. It is expected to follow the crude oil to fluctuate, and its current valuation is relatively low [4][11]. - **PX**: The market lacks clear news guidance, and the price fluctuates in a range under the game between cost and sentiment. The cost - side guidance is limited, and the short - term supply - demand pattern is acceptable under the support of the downstream polyester load [12]. - **PTA**: New Fengming starts new and stops old, and the short - term new supply is limited. The upstream cost is in a stalemate, and the supply has not significantly decreased. There is a certain expectation of improvement in the short - term supply - demand pattern, and the price is not likely to fall deeply in the short - term [12]. - **Short - Fiber**: Downstream factories are digesting their previous stockpiles, and the processing fee is expected to be compressed to a certain extent. The upstream cost fluctuates, and the short - fiber itself has no independent market, with limited supply - demand variables and general driving forces [18][19]. - **Bottle Chip**: The cost is in a stalemate, and the supply - demand drive is limited. The upstream polyester raw materials fluctuate within a range, and the polyester bottle chip price follows suit. The medium - term supply - demand is expected to weaken, and the processing fee is in a stalemate [20]. - **Methanol**: There is slight support at the 2100 integer level, and it fluctuates. The domestic methanol factory operating rate is at a high level, and the supply is abundant. The port inventory is high, but considering the possible disturbances from Iran in winter, it still has low - buying value [23]. - **Urea**: High inventory suppression and cost support coexist, and it is expected to fluctuate in a narrow range. The supply is at a high level and fluctuates, the demand for winter wheat is coming to an end, and the high inventory suppresses the upward space of the futures price, while the coal cost provides support [24]. - **Ethylene Glycol**: The supply - demand contradiction has become the focus of the market again, and the pessimistic sentiment is difficult to reverse. The supply pressure is difficult to relieve in the short - term, and the market is worried about a new round of capacity release. The port inventory is expected to continue to increase [16]. - **Styrene**: There are still concerns about inventory over - filling, and it fluctuates weakly. The cost - side pure benzene supply has some disturbances, but it does not reverse the situation. The supply - demand difference in November is negative, and the port inventory pressure is still large [14]. - **PVC**: The market sentiment has cooled down, and it fluctuates weakly. The macro - level disturbances have subsided in November, and the PVC fundamentals are under pressure. The cost is stable, the production will increase after the end of the upstream maintenance, and the export is weak [28]. - **Caustic Soda**: It has a low valuation and weak expectations, and it fluctuates. The macro - level disturbances have subsided in November, and the fundamentals are improving, but the driving force may be limited. Attention should be paid to the cost support [29]. - **Plastic**: The short - term maintenance has decreased, and it is in a weak pattern. The oil price fluctuates, the plastic's own fundamental support is limited, the upper - and middle - stream still have the intention to reduce inventory at high prices, and the short - term maintenance has decreased, increasing the production pressure [25]. - **PP**: The fundamental support is limited, and it weakens. The oil price fluctuates, the PP's own fundamental support is limited, the current maintenance has decreased, the production has increased year - on - year, and the middle - stream inventory is at a high level in the same period of the past five years [26]. - **Propylene (PL)**: The downstream transaction improvement is limited, and it fluctuates. The CP prices of propane and butane announced by Saudi Aramco in November have decreased. The downstream demand is differentiated, suppressing the enterprise's shipment rhythm [27]. 3.2 Variety Data Monitoring - **Inter - period Spread**: The inter - period spreads of various varieties such as Brent, Dubai, PX, PTA, etc. show different changes. For example, the M1 - M2 spread of Brent is 0.4 with a change of 0.03, and the 1 - 5 month spread of PX is - 8 with a change of 8 [31]. - **Basis and Warehouse Receipts**: The basis and warehouse receipts of different varieties are presented. For example, the basis of asphalt is - 26 with a change of - 3, and the warehouse receipt is 7690 [32]. - **Inter - variety Spread**: The inter - variety spreads such as 1 - month PP - 3MA, 1 - month TA - EG, etc. have different values and changes. For example, the 1 - month PP - 3MA spread is 68 with a change of - 147 [33].

Report Industry Investment Ratings No relevant content provided. Core Views Polyolefin Industry - Supply: PP supply recovery slowed due to more unplanned maintenance, while PE supply is expected to increase as maintenance nears its peak. Overseas inventory clearance at the end of the year may impact the market [2]. - Demand: Demand has improved with increased downstream开工率, but the peak season for agricultural film is approaching, and demand is expected to decline [2]. - Strategy: The 01 contract faces inventory pressure, while the 05 contract may present long - term low - buying opportunities. A reverse spread strategy for the monthly spread is recommended [2]. Methanol Industry - Supply: The port methanol market is under pressure due to high inventory, postponed Iranian gas restrictions, and increased imports. The restart of domestic devices and overseas device shutdowns also affect the supply [5][6]. - Demand: Multiple MTO units reduced their loads due to profit issues, and subsequent maintenance is expected to increase [6]. - Strategy: The 01 contract will continue to trade the "weak reality" logic until Iranian gas restrictions take effect [6]. Polyester Industry Chain - PX: Supply is stable despite some plant maintenance, and demand has support in the short term. However, the November supply - demand is expected to be loose, and oil price support is limited. Strategies include reducing long positions above 6600 and short - selling on rallies, and narrowing the PX - SC spread [9]. - PTA: There are many planned maintenance in November, and demand is relatively high. But supply - demand is slightly loose, and oil price support is weak. Strategies include reducing long positions above 4600, short - selling on rallies, and a rolling reverse spread for TA1 - 5 [9]. - Ethylene Glycol: Overseas supply is high in November, and inventory accumulation is expected. Strategies include selling out - of - the - money call options on rallies and a reverse spread for EG1 - 5 [9]. - Short - fiber: Supply is high in the short term, but demand may decline seasonally. Cost support is limited. Strategies are similar to PTA, and narrowing the processing margin on rallies [9]. - Bottle - chip: Supply changes little, and demand is weak in the off - season. The market is in a loose supply - demand pattern, and the price follows the cost. Strategies are similar to PTA, and the processing margin is expected to fluctuate between 300 - 450 yuan/ton [9]. Pure Benzene - Styrene Industry - Pure Benzene: Supply is expected to be loose with many device restarts and new capacity. Demand support is limited as downstream products are mostly in losses. Inventory in East China ports is increasing. Strategies include short - selling on rallies following oil price movements [10]. - Styrene: Supply may slightly decrease, and demand is expected to remain stable. Cost support is weakening. The market is currently in a loose supply - demand situation, and the price drive is limited. Strategies include short - selling on price rebounds for the EB12 contract [10]. PVC - Caustic Soda Industry - Caustic Soda: Supply is expected to increase in November with few maintenance enterprises. Demand support is weak as the alumina price is falling and downstream enterprises are consuming their own inventories. The price is expected to be weakly stable, and the overall trend is bearish [11]. - PVC: The supply - demand surplus situation persists. Demand from real estate and other downstream industries is weak, and new capacity will increase supply in November - December. The price is expected to continue to oscillate weakly at the bottom, and a short - selling strategy on rebounds is recommended [11].
