Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. Core Views Crude Oil - Wednesday saw a rebound in crude oil prices due to geopolitical tensions and the Fed's interest - rate cut. However, the supply - demand pattern remains loose. Short - term Brent crude is expected to fluctuate between $60 - 65 per barrel. Keep an eye on the US - Venezuela situation and Russia - Ukraine negotiations [1]. Natural Rubber - Overseas supply increase expectations are rising, and upstream cost support is weakening, but the market may have speculative sentiment. Demand from the tire industry is gradually recovering, but overall capacity utilization improvement is limited. Market inventory is being digested. It is expected that rubber prices will fluctuate between 15,000 - 15,500 [4]. Urea - Urea futures fluctuated and closed higher. Shandong Ruixing's production reduction boosted the spot price in the central region. Downstream demand and export orders reduced the inventory pressure. However, the overall supply - demand outlook is weak, and the price rebound space is limited. Short - term urea is expected to continue to fluctuate between 1630 - 1700 [6]. Methanol - Methanol futures oscillated at a low level. The inland supply increased, but profits were weak. The traditional downstream demand increased slightly, and winter fuel demand provided support. Port imports are expected to decline significantly, and the port de - stocking expectation is strengthened, but the current overseas shipments are still high. Continue to pay attention to MTO05 [7]. Polyolefins - The fundamentals of polyolefins show a pattern of increasing supply and weakening demand, with cost support and inventory pressure coexisting. Polypropylene's supply - side maintenance is high, but there is an expectation of an increase. Polyethylene's supply is increasing, and the upstream inventory is still higher than the same period in previous years [12]. Glass and Soda Ash - Soda ash's supply is high, demand is shrinking, and it is expected to return to the inventory - accumulation pattern. The overall situation is bearish, and short positions can be held. Glass prices were affected by real - estate news, and the current short - term demand has support, but the medium - and long - term outlook is not optimistic [14]. PVC and Caustic Soda - Caustic soda's supply and demand are under pressure, and prices are expected to continue to weaken. PVC's supply pressure remains high, demand is weak, and the overall situation is in an oversupply pattern, with prices expected to continue to be weak at the bottom [15]. Polyester Industry Chain - PX is expected to oscillate between 6600 - 7000 in the short term. PTA is expected to oscillate between 4500 - 4800 in the short term, and TA5 - 9 can be long - short hedged at a low level. Ethylene glycol is expected to oscillate at a low level, and short - term observation is recommended. Short - fiber prices are expected to follow the raw materials and oscillate weakly. Bottle - chip prices follow the cost and the processing fee is expected to be squeezed [16]. LPG No specific view on the trend of LPG is provided in the report, only price, inventory, and开工率 data are presented [19]. Benzene - Styrene - Benzene's short - term supply - demand is weak, and BZ2603 may follow the oil price and styrene fluctuations. Styrene's supply - demand is in a tight balance, but the upside space is limited, and EB01 is expected to oscillate weakly in the short term [21].

1. Investment Ratings - No investment ratings for industries are provided in the reports. 2. Core Views Natural Rubber - The price of Thai raw materials may accelerate its decline. With seasonal inventory accumulation pressure and poor terminal demand, multiple short - term negatives are suppressing the price. It is expected that the rubber price will fluctuate weakly [1]. Crude Oil - There are more positive factors in the news of the short - term crude oil market, and the oil price is generally strong. However, the main logic of the weak supply - demand pattern remains unchanged, and the rebound space of the oil price is limited. It is expected that the short - term Brent oil will fluctuate between $60 - 65 per barrel [4]. Glass and Soda Ash - Soda ash: Although the inventory has decreased in stages, the over - supply problem still exists, and the demand is in a contraction pattern. It is expected to fluctuate weakly at the bottom. - Glass: In the short - term, there is still some rigid demand support, but in the long - term, the demand will shrink, and the price will be under pressure [6]. PVC and Caustic Soda - Caustic soda: There is still pressure on supply and demand, and the price is expected to run weakly. - PVC: The supply pressure remains, and the demand is lackluster. It is expected to continue the range - bound operation and maintain a weak pattern at the bottom [7]. Methanol - The supply of inland methanol increases, but the profit is weak. The traditional downstream demand is supported, and the port is expected to reduce inventory. The price is currently weak [8][9]. Polyolefins - PP: Supply and demand both increase, and the overall valuation is neutral to low. - LLDPE: The supply increases, and attention should be paid to the basis repair near the delivery [14]. Benzene - Styrene - Pure benzene: The supply is expected to remain stable, the demand support is limited, and the port is expected to accumulate inventory. The price drive is weak. - Styrene: The supply pressure eases, the supply - demand structure improves, but the upward space is limited due to weak cost support and seasonal weakening of terminal demand [16]. Urea - The daily production increases, the inventory decreases, and the orders increase. The overall supply - demand situation shows certain changes [17]. LPG - The price of LPG futures and spot shows a certain decline, the inventory decreases, and the downstream PDH start - up rate increases slightly [18]. Polyester Industry Chain - PX: The short - term drive is limited, and the medium - term supply - demand is expected to improve, but the absolute price increase is restricted by the oil price. - PTA: The short - term supply - demand is tight, and it follows the raw material fluctuations. - Ethylene glycol: It is expected to continue to explore the bottom. - Short - fiber: The supply - demand is weak, and the processing fee is compressed. - Polyester bottle - chip: The supply - demand is loose, and the processing fee is expected to be squeezed [20]. 3.

1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - In 2026, the PX market is expected to see both supply and demand increase, with the Chinese PX balance sheet likely to remain in a de - stocking state, though the de - stocking amplitude will narrow compared to 2025. Attention should be paid to the load - increasing situation of Zhejiang Petrochemical and the commissioning progress of Yulong Petrochemical [4][5][13]. - In 2026, without new PTA capacity additions, PTA supply growth is expected to be less than demand growth, leading to continued de - stocking and potential low - level recovery of processing fees. However, the supply elasticity of PTA remains, and attention should be paid to the resumption of production of devices under the recovery of processing fees [8][9][13]. - In 2026, the supply pressure of new MEG capacity will increase. Assuming a 4.9% growth rate in polyester demand, MEG is expected to accumulate inventory, with the price center expected to be lower than in 2025, mostly operating in the range of 3,700 - 4,600 yuan/ton [11][12][14]. - In 2026, the new PF capacity will increase again. After the high - growth in 2025, the direct export of staple fiber in some regions is saturated, and the demand - side growth space is limited. The competition in the staple fiber industry is expected to intensify again, and the processing margin may be compressed [14]. - In 2026, although the production capacity growth of PR will further slow down, due to the previous high - speed supply growth, the processing fee of bottle chips is still under pressure. It is expected to have a slight improvement compared to 2025 but will still fluctuate in the range of 300 - 600 yuan/ton [14]. 3. Summary According to the Directory 3.1 Market News and Important Data - **PX Balance Sheet Data** - Demand: Calculated simply based on the estimated PTA production [4]. - Production: In 2026, China's new PX capacity is planned to be 2.6 million tons, with a capacity growth rate of 6%. The actual new production capacity mainly comes from Liaoning Huajin Aramco's 2 million tons and Fujia Dahua's 0.6 million tons of transformation and expansion. The new capacity is expected to contribute about 1.2 million tons of production in 2026. The average operating rate of China's PX in 2025 is expected to be 87.1%, and in 2026, the PX production is expected to increase by about 2 million tons compared to 2025, with a growth rate of 5.3%, and the average operating rate is estimated at 89% [4]. - Import: In 2026, the import demand is expected to continue to grow, with an estimated import of about 9.99 million tons, a year - on - year increase of 4%, and the import dependence will remain around 20% [5]. - Summary: In 2026, PX supply and demand are expected to increase, and the Chinese PX balance sheet is expected to remain in a de - stocking state, but the de - stocking amplitude will narrow [5]. - **PTA Balance Sheet Data** - Demand: In 2026, the new polyester capacity is planned to be about 4 million tons. The average operating rate of polyester in 2025 is expected to be around 90%, and in 2026, it is expected to rise slightly to 91%. The estimated polyester production in 2025 is 84.64 million tons, with a production growth rate of 4.9%. The non - polyester demand for PTA is expected to be about 2.88 million tons throughout the year [7]. - Production: In 2026, there are no PTA production capacity addition plans in China. However, the production of new devices put into operation in 2025 will gradually increase. It is expected that the total PTA production in 2026 will increase by about 2.9 million tons compared to 2025, with a production growth rate of 3.9%, and the average operating rate is expected to decline from 83% in 2025 to 81% [8]. - Net Export: In 2026, the PTA export volume is expected to decrease slightly compared to 2025 due to the increase in overseas supply [9]. - Summary: In 2026, without new production capacity additions, PTA supply growth is expected to be less than demand growth, and PTA will remain in a de - stocking state, with processing fees expected to recover from a low level [9]. - **MEG Balance Sheet Data** - Demand: Similar to PTA, in 2026, new polyester capacity is planned to be about 4 million tons, and the average operating rate of polyester is expected to rise slightly to 91%. The estimated polyester production in 2025 is 84.64 million tons, with a production growth rate of 4.9%. The non - polyester demand for EG is estimated to be about 1.65 million tons throughout the year [10]. - Domestic Capacity and Production: In 2026, China plans to put into operation 2.8 million tons of MEG capacity, with a nominal capacity growth rate of 9.2%. The new capacity is expected to contribute about 0.95 million tons of production. The production of existing devices is expected to increase by about 1.25 million tons, and the overall domestic MEG production is expected to increase by about 1.8 million tons, with a production growth rate of 8.7% [11]. - Net Import: In 2026, the net import level is about 7.35 million tons, a slight decrease compared to 2025 [12]. - Summary: In 2026, the supply pressure of new MEG capacity will increase, and it is expected to accumulate inventory. The annual price center is expected to be lower than in 2025, mostly operating in the range of 3,700 - 4,600 yuan/ton [12]. 3.2 Market Analysis - **PX**: In 2026, PX supply and demand are expected to increase, and the Chinese PX balance sheet is expected to remain in a de - stocking state, but the de - stocking amplitude will narrow. Attention should be paid to the load - increasing situation of Zhejiang Petrochemical and the commissioning progress of Yulong Petrochemical. PXN is expected to be strong during the aromatics blending stockpiling and PX centralized maintenance periods and weak at other times [13]. - **PTA**: In 2026, without new production capacity additions, PTA is expected to remain in a de - stocking state, and processing fees are expected to recover from a low level. However, attention should be paid to the resumption of production of devices under the recovery of processing fees [13]. - **MEG**: In 2026, the supply pressure of new MEG capacity will increase, and it is expected to accumulate inventory. The annual price center is expected to be lower than in 2025, mostly operating in the range of 3,700 - 4,600 yuan/ton [14]. - **PF**: In 2026, the new PF capacity will increase again. After the high - growth in 2025, the direct export of staple fiber in some regions is saturated, and the demand - side growth space is limited. The competition in the staple fiber industry is expected to intensify again, and the processing margin may be compressed [14]. - **PR**: In 2026, although the production capacity growth of PR will further slow down, due to the previous high - speed supply growth, the processing fee of bottle chips is still under pressure. It is expected to have a slight improvement compared to 2025 but will still fluctuate in the range of 300 - 600 yuan/ton [14]. 3.3 Strategies - **PX and PTA**: For the 05 contract, consider long - hedging on dips. Pay attention to the 5 - 9 positive spread opportunity in the inter - period spread and the opportunity to go long on PTA processing fees in the inter - variety spread. In 2026, there are no new PTA device additions, and downstream polyester still has new capacity additions, so the PTA supply - demand situation will improve. PX new devices will mainly be put into operation in the second half of the year, and PX is expected to be tight in the first half of the year, so the 5 - 9 positive spread opportunity can be considered [15]. - **MEG**: The annual - level unilateral price is expected to mostly operate in the range of 3,700 - 4,600 yuan/ton. The 01 contract is expected to be under pressure due to the new device commissioning, the 05 contract may have a rebound opportunity, and the 09 contract may be under pressure again due to the concentrated commissioning of devices [16].

1. Report Industry Investment Ratings There is no information about industry investment ratings in the provided reports. 2. Core Views of the Reports Methanol - In the inland market, Jiutai's maintenance is over, and domestic production will continue to increase. Currently, marginal inland plants are in the red, and attention should be paid to their operating conditions. Some Iranian plants have started to limit gas and stop production, market sentiment has improved, short - sellers have reduced their positions, and the futures price and basis have both strengthened. In the short term, it is expected to fluctuate strongly. Follow the timing and intensity of gas restrictions [1][2][4]. Rubber - The domestic rubber - producing areas are gradually entering the production - reduction and tapping - suspension season, and floods in southern Thailand and Vietnam are yet to subside, providing strong support to the cost side. Overseas shipments are seasonally increasing, and the accumulation of natural rubber inventory suppresses spot prices. Overall demand is weak, and it is expected that the natural rubber market will enter a range - bound consolidation. Follow the raw material output in the main producing areas during the peak season and macro - level changes [5]. Polyolefins - PDH profits continue to weaken this week. PP shows a pattern of both supply and demand increasing, with reduced maintenance driving supply recovery and a slight reduction in inventory. PE shows an increase in supply and a decrease in demand. Despite the alleviation of some supply pressure from planned maintenance, imported supplies are abundant. Except for agricultural films, other demand is generally weak, and inventory accumulates slightly under the pressure of new production capacity. The 01 contract is still under significant pressure [8]. Crude Oil - The uncertainty of the Russia - Ukraine negotiations and the decrease in the number of US oil rigs support short - term oil prices, and international oil prices rose slightly overnight. However, under the pressure of continuous OPEC+ production increases and a record - high US crude oil production, the crude oil supply - demand pattern remains weak. It is expected that oil prices will continue to fluctuate at a low level, and short - term Brent crude oil should be watched for support at $60 per barrel. Pay attention to the results of the Russia - Ukraine negotiations [10]. Glass and Soda Ash - Soda ash: The overall supply - demand pattern is still bearish. This week, some plants reduced their loads, leading to a decline in weekly production and a phased reduction in soda ash plant inventory. In the medium term, downstream demand is expected to remain at the previous rigid - demand level. It is recommended to wait for a rebound and then go short. Hold short positions entered at high prices this week, and those who have not entered the market should wait and see [12]. - Glass: In the short term, there is still some rigid - demand support during the year - end rush season. However, in the long term, as the peak season ends, there are concerns about the sustainability of demand. After December, the demand side will shrink, and glass prices will be under pressure. The real - estate market is still at the bottom of the cycle, and the glass industry needs to clear its inventory. The 01 contract is still under pressure as the delivery month approaches, but it is expected to be strong in the short term, with a 1 - 5 reverse - spread strategy [12]. PVC and Caustic Soda - Caustic soda: There is still some pressure on the supply - demand side. Next week, the regional supply in East China will decline, but monthly contracts will be signed. If the futures price continues to weaken, it is estimated that the spot price in East China will also decline. The Shandong market is unclear, and the unloading situation of major downstream products and the trend of liquid hydrogen need to be monitored. Overall, demand support is weak, and in the long term, supply - demand pressure remains. It is expected that caustic soda prices will run weakly [13]. - PVC: The spot market continues to be weak. This week, the operating rate on the supply side will increase, while demand remains sluggish. Pay attention to the release of Asian contract prices in December. From November to January of the next year is the traditional off - season, and the reduction in real - estate demand in the north is a negative factor. Although India has cancelled the BIS certification policy for imported PVC, the expected implementation of anti - dumping duties means that external demand is difficult to increase. The supply - demand situation remains in an oversupply pattern, and prices are not optimistic. It is expected to continue the weak trend at the bottom [13]. Polyester Industry Chain - PX: Short - term drivers are limited, but in the medium term, the supply - demand outlook is expected to be tight, and it is recommended to treat it as a high - level shock in the short term. - PTA: Supply reduction is greater than expected, and polyester operating rates are expected to decline later. After India cancelled the BIS certification, PTA exports are expected to increase. In December, the supply - demand outlook is tight, but in the first quarter, it is generally loose. The absolute price is relatively firm in the short term, but the rebound space is limited. TA is expected to fluctuate at a high level in the short term, and a short - term low - level positive spread can be considered for TA spreads. - Ethylene Glycol: Support is acceptable, but there are many maintenance plans for coal - based ethylene glycol plants. North American and Middle Eastern ethylene glycol operating rates are high, and import volumes are expected to be significant. Port inventory has limited downward space, and it is expected to fluctuate at a low level. It is recommended to go short on the EG1 - 5 spread at high levels. - Short - fiber: Supply - demand remains weak. Although the spot processing fee has been compressed, there is still profit, and factory inventory pressure is low, so supply remains high. Terminal demand is seasonally weak in November. It is expected that the absolute price has limited drivers, and the processing fee will continue to be compressed. The strategy is the same as for PTA, and the processing fee on the futures market should be shorted when it is high. - Bottle - grade polyester chips: Domestic supply is gradually increasing, while demand is weak during the off - season. The social inventory of bottle - grade polyester chips is likely to enter a seasonal accumulation period, and the price will follow the cost side. The processing fee is expected to decline. The strategy is the same as for PTA, and it is recommended to short the processing fee on the main futures contract, which is expected to fluctuate between 300 - 450 yuan per ton [14]. Benzene - Styrene - Although the short - term supply - demand outlook for styrene has improved, with the recovery of industry profits and the expectation of weakening demand, combined with weak cost - side support, the rebound space of styrene is limited, and overall drivers are insufficient. The EB01 contract should be treated as a shock consolidation. Follow the changes in styrene plants and actual export transactions [15].

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 No relevant content provided. Core Viewpoints of the Report - The overall market shows a complex and volatile situation, with different sectors having different trends and influencing factors. For example, the A - share market is affected by macro - data and shows an upward - then - downward trend; the steel and ore market is expected to be weak in the medium - to - long - term; and the energy market is influenced by geopolitical conflicts and supply - demand relationships [10][12][35]. Summary by Related Catalogs Macro Information - The 22nd issue of Qiushi magazine published President Xi Jinping's important article. The National Bureau of Statistics released October economic data, showing a slowdown in multiple indicators. The prices of commercial housing in 70 cities declined. The Chinese government reminded citizens to avoid traveling to Japan. The State Council studied "two - important" construction and consumption - promotion policies. The central bank will conduct a large - scale reverse - repurchase operation. The US will release multiple economic data. The Guangzhou Futures Exchange will list platinum and palladium futures. The market supervision department issued an anti - monopoly compliance guide. The national child - rearing subsidy system has been implemented, and the lithium - battery industry chain has seen a price increase. Trump adjusted the scope of "reciprocal tariffs" [4][5][6][7][8]. Macro Finance - **Stock Index Futures**: Adopt a volatile mindset and temporarily hold off on trading. The A - share market rose and then fell, affected by macro - data. The decline in industrial growth, consumption, and investment may be due to technical factors, export slowdown, anti - involution, and the real - estate downturn [10]. - **Treasury Bond Futures**: The market's expectation of monetary easing has declined, but interest - rate cuts cannot be ruled out. Maintain the view of increased easing in Q4. The money market is affected by the approaching tax period, and the stock - bond seesaw effect is weakly effective [11]. Black - **Steel and Ore**: In the short - term, expect a volatile consolidation; in the medium - to - long - term, maintain a bearish view when prices are high. The supply - demand relationship is weak, with high inventory and low profit for steel mills. The price is affected by low - price transactions and may remain weak [12][13]. - **Coking Coal and Coke**: The prices may continue to decline in the short - term. In the medium - term, the mine's production is restricted by policies, and the demand for steel is weak in the off - season, but the strong thermal - coal price provides some support [14]. - **Ferroalloys**: In the long - term, the oversupply situation is difficult to alleviate, so maintain a bearish view when prices are high. In the short - term, it is recommended to wait and see. The prices are fluctuating narrowly, and the cost of manganese - silicon is relatively stable [15]. - **Soda Ash and Glass**: Currently, it is recommended to wait and see. The soda - ash industry has production fluctuations and cost increases, while the glass industry's strong sales have not continued, and the market is concerned about demand and inventory [16]. Non - ferrous Metals and New Materials - **Lithium Carbonate**: The short - term fundamentals are good, but the demand may weaken in Q1 next year, limiting price increases. After the demand weakens, the price may correct, and it is advisable to buy on dips [18]. - **Industrial Silicon and Polysilicon**: Industrial silicon has no prominent supply - demand contradictions and can be bought on dips or sell out - of - the - money put options. Polysilicon is expected to continue to fluctuate, influenced by policy expectations and supply - demand relationships [19]. Agricultural Products - **Cotton**: The supply pressure is large, and the demand is weak. The price is undervalued compared to the spot, which limits the decline. It is expected to oscillate at a low level [23][24]. - **Sugar**: The domestic sugar supply - demand situation is expected to be bearish. Before the large - scale arrival of new sugar, it is advisable to wait and see. In the long - term, there is still supply pressure [25][27]. - **Eggs**: The spot price is weak, and the futures price may oscillate. The in - production laying - hen inventory is high, but it is expected to decline. It is recommended to short the near - term contracts [28]. - **Apples**: The price is expected to be strong in a volatile manner. The inventory is low, and the price is high. The future consumption trend will be the focus [30]. - **Corn**: The spot price has rebounded, but the supply pressure is still accumulating. It is necessary to pay attention to the new - grain sales progress and the release of policy wheat [31]. - **Red Dates**: Temporarily wait and see. The weak spot market in the sales area has a negative impact on the new - date ordering price [32]. - **Pigs**: The supply pressure continues, and the demand is average. The spot price is likely to oscillate weakly. It is recommended to short the near - term contracts [33]. Energy and Chemicals - **Crude Oil**: In the short - term, it is expected to be strongly volatile, but the long - term downward trend of oversupply remains unchanged. The price is affected by geopolitical conflicts and supply - demand forecasts [35]. - **Fuel Oil**: The price will follow the oil price, with a supply - abundant and demand - weak structure. The short - term focus is on supply concerns after the sanctions on Russia [36]. - **Plastic**: The supply pressure is large, and it is expected to be weakly volatile. The current price provides some support for producers [36][37]. - **Rubber**: Pay attention to the strategy of expanding the ru - nr spread. The price may oscillate in the short - term, with supply in the peak season and support at the bottom [37]. - **Methanol**: The near - term contracts are expected to be weakly volatile, and the far - term contracts can be moderately long after the rebound drive appears. The supply pressure is large, and the inventory is high [38][39]. - **Caustic Soda**: Wait for long - position opportunities after a significant decline. Pay attention to the cost support. The spot price is falling, and the futures price is weak [40]. - **Asphalt**: The price fluctuation is expected to increase, and the focus is on the price bottom after the winter - storage game [41]. - **Polyester Industry Chain**: It is expected to continue to be strong in the short - term, driven by improved supply - demand and market sentiment [42]. - **Liquefied Petroleum Gas**: Although there are short - term positive factors, it is not advisable to chase the rise. Consider shorting at high prices in the medium - to - long - term [43]. - **Paper Pulp**: The fundamentals are relatively stable, and it is expected to maintain a wide - range oscillation. Observe the digestion of old warehouse receipts and spot transactions [45]. - **Logs**: The fundamentals are weakly oscillating, and the price is under pressure. The inventory is expected to increase, and the market is in the off - season [46]. - **Urea**: Wait and see, subject to specific policies. The spot price is falling, and the futures price is oscillating [47]. - **Synthetic Rubber**: The short - term price will oscillate within a range. Be cautious when going long and consider selling call options after the rebound [48].

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Crude Oil - Despite concerns about crude oil supply glut, US government's end of shutdown and tightened sanctions on Russia led to a slight rebound in overnight oil prices. OPEC+ faces continuous production - increase pressure, with a weak fourth - quarter supply - demand outlook. EIA周报 shows significant increase in US crude production and large inventory growth, so oil prices remain under pressure. Short - term Brent may trade in the range of $60 - 66 per barrel, with a bearish view. Attention should be paid to substantial sanctions on Russia and the Russia - Ukraine geopolitical situation [2]. Polyolefins - PP shows both supply and demand increase. Supply rises due to fewer maintenance, and demand remains resilient in the automotive and home - appliance sectors, but there is slight inventory accumulation this week under new - capacity pressure. PE has weak supply and demand. Although unplanned maintenance eases supply pressure, import sources are abundant, and non - agricultural - film demand generally declines. There is inventory reduction this week, but port inventory remains high. The cost side has crude oil fluctuating and coal strengthening, with a slight repair in PDH profit. High inventory and cost support continue to compete, and market expectations are still weak [4]. Methanol - Delayed gas restrictions in Iran put significant pressure on the port methanol market. High inventory, combined with positive import profit from Iran, leads to continuous trading and weakening willingness to hold goods, resulting in price decline and stable basis. In the inland market, Baofeng continues external procurement, and Jiutai has unexpected maintenance, with subsequent increase in domestic production. Overseas gas restrictions are less than expected. On the demand side, multiple MTO units reduce load due to profit reasons, and traditional downstream purchases for rigid demand. The market currently trades on the "weak reality" logic, with the core contradiction being high port inventory. The inventory problem of the 01 contract cannot be solved, and the weak reality will continue to be traded before gas restrictions in Iran [8]. Natural Rubber - On the supply side, there are still periodic rainfall disturbances in overseas production areas, but overall, a strong output is expected during the peak - production period, and raw - material prices have some downward space. Domestic production areas are gradually entering the output - reduction period, with firm domestic raw - material prices. On the demand side, some northern regions are entering the off - season in the month, with slower market sales, mainly digesting inventory and purchasing as needed. With market digestion, some replenish in small quantities in the middle of the month. In the short term, due to large macro fluctuations, rubber prices are expected to fluctuate. Follow the raw - material output in the peak - production period of major production areas and macro changes. If raw - material supply is smooth, prices may weaken; if not, rubber prices are expected to trade around 15,000 - 15,500 [11]. PVC and Caustic Soda - **Caustic Soda**: Low - concentration caustic soda gets price support from increased inquiries from alumina plants, but overall, there is a lack of real positive factors. The caustic - soda industry still faces supply - demand pressure, with few maintenance enterprises and an increasing supply. The main downstream alumina price is weakening, with shrinking industry profit and increasing losses, so the main demand side provides weak support, suppressing caustic - soda prices. Although there may be periodic replenishment demand from middle - and downstream inventory consumption, prices are still under pressure due to increasing supply and weakening demand. The non - aluminum market is sluggish. It is expected that caustic - soda prices will trend down in the long run, but there is short - term support from downstream periodic demand. Track the rhythm and sustainability of downstream replenishment [12]. - **PVC**: The supply - demand surplus problem has not improved, with increasing supply pressure, weakening demand expectations, insufficient cost support, and no positive macro expectations. It is expected that prices will continue to weaken. On the demand side, major downstream sectors such as real estate are still weak, and product enterprises like profiles and pipes have limited new orders, mainly purchasing for rigid demand, which cannot provide continuous market support. In November - December, there will still be an impact from new production capacity. After the maintenance of Inner Mongolia Sanlian, Qilu Petrochemical, and Inner Mongolia Junzheng ends next week, production is expected to increase. From November to January of the next year is the traditional off - season, with reduced outdoor construction in the north, and overall real - estate demand decline is a negative factor. The situation of anti - dumping duties in India is unclear, and exports are mainly in a wait - and - see state. The supply - demand surplus persists, and prices are not optimistic, expected to continue weakening at the bottom [12]. Glass and Soda Ash - **Soda Ash**: Recently, with the previous price decline, middle - and downstream buyers have increased purchases, leading to a rebound in the futures price. However, the overall surplus situation is still prominent. Fundamentally, weekly production remains at a high level of around 750,000 tons, with obvious surplus compared to current rigid demand. Manufacturer inventory has been transferred to the middle - and downstream, and trade inventory continues to rise. In the medium term, there is no expectation of significant downstream capacity increase, so the overall demand for soda ash will continue the previous rigid - demand pattern. Without actual capacity exit or load reduction, the supply - demand situation will face further pressure. Track macro fluctuations and soda - ash plant load - adjustment situations. The supply - demand outlook is bearish. Short - term operation should be on the sidelines, and wait for opportunities to short on rebounds [13]. - **Glass**: Sales have weakened significantly, and the sales - to - production ratio has fallen below 100% in recent days. Although four production lines in the Shahe area were cold - repaired last week, there will be production - line restart and ignition, adding about 3,650 tons of daily capacity, which will put pressure on the supply side. The latest deep - processing order days have slightly improved, and there is still some rigid demand support in November as it is the year - end rush season. However, in the long - term, at the end of the peak season, there are concerns about future demand sustainability. As the temperature drops in the north, outdoor construction will stop, and glass prices will face pressure after December. The real - estate industry is still in the bottom cycle, with significant reduction in construction volume. The industry needs capacity exit to solve the surplus problem. The high sales - to - production ratio of spot has ended, and glass is expected to be weak in the short term [13]. Polyester Industry Chain - **PX**: Currently, Asian and domestic PX loads remain high. In the short - term, PTA load is maintained, and the previous terminal and polyester demand was better than expected. With low polyester inventory, load is expected to remain relatively high from November to December. PX demand still has short - term support. Yesterday, PX showed a strong trend due to the lifting of India's BIS certification and the start of the Asia - America aromatics arbitrage. However, limited by weak overall oil - price support and expected weakening of terminal demand in the industry chain, the PX rebound space is restricted. Short - term PX short positions should be avoided [14]. - **PTA**: There are still many PTA plant maintenance plans in November. The previous terminal and polyester demand was better than expected. With low polyester inventory, load is expected to remain relatively high in November - December. The supply - demand balance in November is expected to be tight, but it will be loose from December to the first quarter of next year. Yesterday, PTA showed a strong trend due to the cancellation of India's BIS certification and PX transfer - demand news, but the spot - market negotiation atmosphere was dull, and the basis was still weak. The PTA rebound space is restricted. Short - term TA should pay attention to the $4800 pressure level, and short positions should be avoided. TA1 - 5 can be treated as a rolling reverse spread [14]. - **Ethylene Glycol (EG)**: Recently, some coal - based EG plants are under maintenance, but Jinghai Petrochemical's plant has restarted production. Previously - maintained coal - based plants plan to restart in the middle - and late - November. Domestic supply remains high, and North American EG load has reached a high level. Middle - East supply shows no reduction, and overseas shipments are concentrated in January. Currently, polyester load is declining, and due to the high expected inventory accumulation in November - December, EG is under pressure. Hold out - of - the - money call options on EG2601 with a strike price of no less than 4100; go for reverse spreads on EG1 - 5 at high prices [14]. - **Short - fiber**: Currently, short - fiber factories have low inventory levels and reasonable processing fees, so short - fiber supply remains relatively high. In November, there is an expected seasonal weakening of terminal demand. Yesterday, the cancellation of India's BIS certification made raw - material PTA stronger, but it mainly benefited PTA and long - fiber, having relatively little impact on short - fiber. In the short - term, due to the weak supply - demand expectation, the short - fiber rebound space is restricted, and processing fees are expected to be compressed. The strategy is the same as PTA for single - side trading; the processing fee on the disk fluctuates in the range of 800 - 1100, and short positions should be taken at high prices [14]. - **Bottle - grade polyester chips**: In mid - November, the Huarun plant has both maintenance and restart. According to Longzhong Information, the commissioning of Dongying Fuhai's new plant is postponed, and domestic supply changes little. Considering the November market off - season, soft - drink and catering demand decline slightly, and demand provides insufficient support for bottle - grade chips. The supply - demand situation remains loose. Bottle - grade chips' social inventory is likely to enter the seasonal inventory - accumulation phase, with prices fluctuating with the cost side. Processing fees are limitedly boosted by supply - demand and change with raw - material costs. The strategy for single - side trading is the same as PTA; the main - contract processing fee on the disk is expected to fluctuate in the range of 300 - 450 yuan per ton [14]. Pure Benzene and Styrene - **Pure Benzene**: There are new capacity commissioning, plant restart, and planned/unplanned maintenance expectations for pure benzene recently, but overall domestic supply may remain loose. On the demand side, some loss - making downstream products have production - reduction and price - protection expectations, so demand support is limited. Although East - China port inventory decreased this week, supply pressure remains. There is an expected amount of imports from November to December, but the US - Asia arbitrage window and gasoline - blending may disrupt market sentiment, and the actual impact needs further consideration. With weak crude - oil supply - demand expectations, cost support is limited, and the rebound space is restricted. Follow plant changes. In the short - term, BZ2603 has weak self - driving force, pay attention to the 5640 pressure level, and be cautious about chasing up [16]. - **Styrene**: Two new styrene plants are operating stably, and previously - shut - down plants have restarted. There are also expected planned/unplanned maintenance in the near future, so overall supply may remain stable. Downstream EPS enters the seasonal off - season and reduces its operating rate due to high product inventory. PS has new plant commissioning and restart, and ABS remains stable. Overall demand changes little. Although inventory decreased this week, it is still at a high level, restricting the upside. Overseas and plant accidents may disrupt the domestic market. Overall, styrene supply - demand is expected to be in a tight balance, with insufficient price - driving force. Follow plant restart and production - reduction situations and cost changes. In the short - term, EB12 price may fluctuate with the cost side [16]. 3.

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views Polyester Industry - PX: In the short - term, it may fluctuate between 6200 - 6800. Suggest to reduce long positions on rallies and short above 6800 [1]. - PTA: It is expected to have a limited rebound, with short - term trading range between 4300 - 4800. Adopt a rolling reverse spread strategy for TA1 - 5 [1]. - Ethylene Glycol: Hold out - of - the - money call options with a strike price of no less than 4100 for EG2601 and conduct a high - level reverse spread for EG1 - 5 [1]. - Short Fiber: The rebound space is limited, and the processing fee may be compressed. The strategy is the same as PTA, and the processing fee on the disk may fluctuate between 800 - 1100 [1]. - Bottle Chip: PR follows the cost - end fluctuations, and the processing fee on the main contract disk is expected to fluctuate between 300 - 450 yuan/ton [1]. Methanol Industry The market is trading the "weak reality" logic, with the core contradiction being high port inventory. Before the gas restriction in Iran, the 01 contract's inventory problem cannot be solved [2]. Polyolefin Industry PP and PE have differentiated fundamentals. PP shows both supply and demand growth but accumulates inventory slightly this week. PE has weak supply and demand, with high port inventory. The market outlook remains weak [5]. Glass and Soda Ash Industry - Soda Ash: The overall supply - demand pattern is bearish. In the short - term, it is advisable to wait and see, and look for opportunities to short on rebounds later [7]. - Glass: It is expected to be weak in the short - term. In the long - term, the industry needs capacity clearance to solve the over - supply problem [7]. PVC and Caustic Soda Industry - Caustic Soda: The price is expected to trend downwards in the long - term but may have short - term support from downstream demand. Monitor the downstream restocking rhythm [8]. - PVC: The supply - demand remains in an over - supply pattern, and the price is expected to continue the weak trend at the bottom [8]. Natural Rubber Industry In the short - term, the rubber price is expected to fluctuate. If the raw material output in the main production areas is smooth, there is further downside potential [9].

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views of the Reports Natural Rubber Industry - The natural rubber market may enter a seasonal inventory accumulation cycle, with short - term price fluctuations in a range. If raw material supply is smooth, there is further downward potential; if not, the price is expected to range between 15,000 - 15,500 [1]. Glass and Soda Ash Industry - For soda ash, the supply - demand pattern is bearish in the medium - long term, and short - term rebounds can be used as opportunities to go short. For glass, there are short - term trading opportunities for low - level rebounds, but the industry still needs capacity clearance [3]. Methanol Industry - The market is trading on the "weak reality" logic, with the core contradiction being high port inventories. The inventory problem of the 01 contract cannot be resolved, and the weak reality will continue to be priced in before Iranian gas restrictions [6]. Polyester Industry Chain - PX may fluctuate between 6,200 - 6,800; PTA may range between 4,300 - 4,800; for ethylene glycol, hold short - call options and conduct reverse spreads; short - fiber has limited rebound space; bottle - grade polyester chips will follow cost fluctuations [8].
