real - estate data shows mixed trends with new construction area decreasing and completion area increasing [14] PVC - Caustic Soda - Caustic soda supply is abundant, and demand support is weak; PVC supply pressure remains, and demand is in the off - season, but export orders are relatively good [15] Polyester Industry Chain - PX supply is expected to be better in the medium - term, and PTA supply decreased more than expected, while demand support is stronger than expected; MEG inventory accumulation in December is expected to narrow, but supply pressure remains [16] Group 4: Industry Core Views and Strategies Polyolefin - The fundamentals show a pattern of increasing supply and weak demand, with cost support and inventory pressure coexisting [2] Methanol - Inland supply increases, and port imports are expected to decline, with winter fuel demand providing support [6] Crude Oil - International oil prices are expected to continue range - bound, with Brent likely to fluctuate between 60 - 65 dollars/barrel in the short - term [9] Natural Rubber - The market is expected to maintain range - bound consolidation, with rubber prices expected to operate between 15000 - 15500 yuan/ton [10] Urea - No specific overall view and strategy are clearly stated in the provided text [12] Benzene - Styrene - For pure benzene, short - term BZ2603 is recommended to be short on rebounds; for styrene, short - term EB01 is recommended to be treated as wide - range fluctuations [13] Glass - Soda Ash - Soda ash is expected to be in a bottom - range fluctuation, and glass is expected to face pressure in the medium - and long - term, with the 01 contract having pressure in December [14] PVC - Caustic Soda - Caustic soda prices are expected to be weak, and PVC is expected to continue the bottom - weakening pattern [15] Polyester Industry Chain - PX is recommended to pay attention to the pressure around 7000 yuan/ton in the short - term; PTA is expected to be in a high - level range - bound in the short - term; MEG is expected to be in a range - bound in December; short - fiber follows raw material fluctuations, and processing fees are recommended to be shorted on highs; bottle - chip processing fees are expected to be squeezed [16]

1. Report Industry Investment Ratings No investment ratings were provided in the reports. 2. Core Views Polyolefins - The fundamentals of LLDPE and PP show a pattern of increasing supply and weak demand, with both cost support and inventory pressure coexisting [2]. Methanol - The supply of inland methanol increases with the restart of devices, but the profits of coal - and gas - based production are weak. The traditional downstream demand has a slight increase, and the winter fuel demand provides support. In ports, the reduction of imports due to Iranian gas restrictions strengthens the de - stocking expectation and supports prices [6]. Natural Rubber - The supply is expected to increase seasonally, and the inventory continues to accumulate. The terminal demand improvement is weak. The market is expected to fluctuate within the range of 15000 - 15500 [9]. Crude Oil - Geopolitical risks support oil prices in the short term, but the continuous increase in OPEC+ production and the record - high US crude oil production put pressure on the supply - demand pattern. Oil prices are expected to fluctuate within a range, with Brent crude oil likely to trade between 60 - 65 dollars per barrel [11]. Polyester Industry Chain - PX: The medium - term supply - demand expectation is good, but the short - term valuation drive is limited. - PTA: The supply - demand is expected to tighten in December but be relatively loose in Q1. The absolute price is relatively firm in the short term, but the rebound space is limited. - Ethylene glycol: It is expected to fluctuate within a range in December. - Short - fiber: The short - term price support is strong, but the absolute price drive is limited, and the processing fee is likely to be compressed. - Bottle - chip: The supply - demand is in a loose pattern, and the processing fee is expected to be squeezed [14]. Pure Benzene and Styrene - Pure benzene: The supply - demand is expected to be weak, and the price is under upward pressure. - Styrene: The supply - demand is in a tight - balance state, but the upward drive is insufficient [15]. Glass and Soda Ash - Soda ash: The supply - demand pattern is still bearish, and it is expected to fluctuate at the bottom. - Glass: The short - term spot market is strong, but the 01 contract may face pressure later [16]. PVC and Caustic Soda - Caustic soda: The demand is weak, and the price is expected to run weakly. - PVC: The supply - demand is in an oversupply pattern, and the price is expected to continue the bottom - range fluctuation [17]. LPG No overall view was provided in the LPG report, but price, inventory, and开工率 data were presented [18]. 3.

Report Industry Investment Ratings No information provided in the given content. Core Views Polyolefins - PP shows a pattern of both supply and demand increasing, with reduced maintenance driving supply recovery and a slight reduction in inventory. PE shows increased supply and decreased demand, with ample imported goods and weakening demand except for agricultural films. Overall, the 01 contract still faces significant pressure [2]. Crude Oil - During the US Thanksgiving, trading was light, and the Russia - Ukraine peace talks were uncertain, leading to a slight increase in overnight oil prices. However, due to OPEC+ continuous production increase and record - high US crude oil production, the supply - demand pattern remains weak. Oil prices are expected to continue to fluctuate at a low level, with short - term focus on the $60/barrel support for Brent crude and the results of the Russia - Ukraine talks [4]. Natural Rubber - On the supply side, domestic production areas are gradually entering the production - reducing and cutting - off season, and floods in southern Thailand and Vietnam need time to recede, providing strong cost support. However, the arrival of overseas shipments is increasing seasonally, and inventory accumulation suppresses spot prices. On the demand side, overall demand is weak, and the market mainly digests channel inventory. Natural rubber is expected to enter a range - bound consolidation, with the price likely to weaken if raw material supply is smooth, and to run in the 15000 - 15500 range if supply is restricted [6]. Methanol - In the inland market, Jiutai's maintenance is over, and subsequent domestic production will continue to increase. Currently, marginal inland plants are in the red. In Iran, some plants have started gas - restricted shutdowns, improving market sentiment and strengthening the futures price and basis. It is expected to be volatile and slightly stronger in the short term [8][9]. LPG No specific overall view provided in the given content. Pure Benzene - Styrene - Pure benzene: New production capacity and plant restarts are expected, and although some plants are reducing production, supply remains loose. Downstream demand is mainly for rigid needs, and some loss - making varieties are reducing production. Port inventory is rising, and short - term prices may be dragged down by oil prices. The strategy is to short on rebounds for BZ2603 in the short term. - Styrene: With profit recovery, some plants are increasing production, but planned and unplanned shutdowns and maintenance are also increasing, limiting supply. Downstream demand support is limited, and overseas blending demand is cooling, but there are still export expectations. The short - term supply - demand outlook is improving, but the rebound space is limited. EB01 is expected to fluctuate and consolidate in the short term [13]. Ester Industry Chain - PX: Short - term supply is relatively high, and demand is weak due to PTA plant maintenance and weakening terminal demand. The short - term driver is limited, but the medium - term supply - demand outlook is tight, and it is expected to fluctuate at a high level in the short term. - PTA: Supply reduction exceeds expectations, and demand from polyester is supported. Exports are expected to increase. The supply - demand outlook is improving, and the basis is recovering. It is expected to be volatile at a high level in the short term, and the strategy is to go long on the TA month - spread at low levels. - Ethylene Glycol (EG): Polyester demand provides some support, but supply from coal - based plants is increasing, and imports are expected to be high. The port inventory has limited downward space. The strategy is to short the EG1 - 5 spread at high levels. - Short - fiber: Supply remains high, and demand is seasonally weak. The absolute price has limited drivers, and processing fees are expected to be compressed. - Bottle chips: Supply is increasing, and demand is in the off - season. The supply - demand pattern is loose, and the processing fee is expected to decline. The strategy is to short the processing fee [14]. Glass - Soda Ash - Soda Ash: Recent production has declined, and inventory has decreased, supporting the futures price. However, the medium - term oversupply problem persists, and demand is expected to remain at the previous rigid level. The supply - demand pattern is bearish, and the strategy is to wait for short - selling opportunities after rebounds. - Glass: News of production line shutdowns in Hubei has boosted the market sentiment, and the futures price has rebounded, driving better spot sales. There is still some short - term rigid demand, but long - term demand is a concern, especially with the approaching winter in the north. The market still needs capacity clearance to solve the oversupply problem. The 01 contract may face pressure near the delivery month [15]. PVC - Caustic Soda - Caustic Soda: The industry still faces supply - demand pressure. Regional supply in East China will decrease next week, but with the monthly contract signing, the spot price in East China is expected to decline if the futures price remains weakening. The demand from the main downstream, alumina, is weak, and the price is expected to be weak in the long term. - PVC: The spot market remains weak. Supply is increasing, and demand is sluggish, especially during the traditional off - season from November to January. Although the cancellation of India's BIS certification is beneficial, the expected anti - dumping tax implementation limits external demand. The supply - demand pattern is in surplus, and the price is expected to continue to be weak at the bottom [16]. Summaries by Related Catalogs Polyolefins - **Prices and Spreads**: L2601 and L2605 prices decreased slightly, while PP2601 and PP2605 prices increased. L15, LP01 spreads decreased, and PP15 spread increased. Spot prices of some products changed slightly [2]. - **Inventory**: PE and PP inventories decreased, with PE enterprise inventory down 9.80% and PP enterprise inventory down 8.00% [2]. - **开工率**: PE device operating rate increased by 2.17%, and PP powder operating rate increased by 6.93%, while PP device operating rate decreased slightly [2]. Crude Oil - **Prices and Spreads**: Brent and WTI prices increased slightly, while SC price decreased. Some spreads such as Brent - WTI decreased [4]. - **Refined Oil**: NYM RBOB price increased, while NYM ULSD and ICE Gasoil prices decreased [4].

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views of the Reports Polyolefins - PP shows a pattern of both supply and demand growth, with reduced maintenance leading to increased supply and a slight accumulation of inventory under the pressure of new production capacity. PE shows increased supply and decreased demand. Although unplanned maintenance eases some supply pressure, imported goods are abundant, and demand is generally weak except for agricultural films. The inventory of hedging merchants is gradually decreasing, the basis is strengthening, and inventory is being cleared. When the price is below 6800, the downstream's willingness to buy increases. The cost side is affected by the shock of crude oil and the strength of coal, and the PDH profit has continued to weaken this week. [2] Methanol - In the domestic market, Baofeng continues to purchase externally, and Jiutai has an unexpected maintenance. The domestic production will continue to increase. Currently, the marginal devices in the domestic market have suffered losses. In the port market, the gas restriction in Iran has been postponed, and the shipment has accelerated. As of November 19, Iran has shipped 885,000 tons, putting significant pressure on the port methanol market. With high inventory and the profit of imported methanol from Iran, the willingness to hold goods has weakened, and the price has declined while the basis remains stable. The demand side is based on rigid procurement. The market is currently trading on the logic of "weak reality", and the core contradiction lies in the high inventory in the port. The inventory contradiction of the 01 contract cannot be resolved, and the weak reality will continue to be traded before the gas restriction in Iran. [4] Glass and Soda Ash - Soda ash: The market has returned to a weak state, and the overall pattern of oversupply is still prominent. Fundamentally, the weekly production remains at a high level of around 750,000 tons, and the oversupply is obvious compared with the current rigid demand. The inventory of manufacturers has been transferred to the middle and lower reaches, and the trade inventory has continued to rise. In the medium term, there is no expectation of a significant increase in downstream production capacity, so the overall demand for soda ash will continue the previous rigid demand pattern. If there is no actual production capacity exit or load reduction in the future, the supply - demand situation will be further pressured. - Glass: The spot sales have strengthened, and the high sales rate in some regions has continued to be above 100%. Consecutive price cuts have driven the middle and lower reaches to purchase. Although 4 production lines in the Shahe area were cold - repaired last week, there will be production lines restarting and igniting in the future, which will put pressure on the supply side. The latest deep - processing order days have improved slightly, and there is still some rigid demand support in the short term as November is the peak season for year - end rush work. However, in the medium and long term, at the end of the peak season, the market is worried about the sustainability of future demand. As the temperature in the north drops, outdoor construction will gradually stop, and the demand side will shrink after December, putting pressure on the glass price. The real estate is still in the bottom cycle, and the completion volume has decreased significantly. Therefore, in the oversupply pattern, the glass industry still needs to clear production capacity to solve the oversupply dilemma. [7] PVC and Caustic Soda - Caustic soda: The supply - demand situation of the caustic soda industry still faces certain pressure. The purchasing enthusiasm of the main downstream alumina has decreased, so the support from the main demand side of caustic soda is weak, which suppresses the caustic soda price upwards. During the northern environmental protection control period, some alumina plants may have production reduction expectations. There is an overhaul expectation in the East China region, and the supply will decrease slightly. The price in this region may be relatively stable due to certain rigid demand support, but in the long term, the supply - demand still has pressure. The non - aluminum market is still sluggish, and overall, the supply - demand pressure is still relatively large. It is expected that the caustic soda price will fluctuate weakly. - PVC: The PVC spot market continues to fluctuate weakly. This week, maintenance and partial device load reduction have led to a decrease in production on a month - on - month basis, but it is still at a high level. Affected by local logistics, the market arrivals have decreased, and the social inventory has decreased on a month - on - month basis. Next week, the supply - side operating rate will increase. The demand side is in the traditional off - season from November to January of the next year. As the outdoor construction in the north gradually decreases in winter, the overall real estate demand reduction still has a negative impact. In terms of exports, India has officially cancelled the BIS certification for imported PVC issued in 2024, which is beneficial for domestic PVC to enter the Indian market. However, there is an expectation of anti - dumping duties, and the Asian contract price for December is still to be observed next week. It is expected that the external demand will be difficult to increase. The overall demand side has limited support for PVC. The supply - demand is still in an oversupply pattern, and it is difficult for the price to form an upward drive. It is expected to continue the weak pattern at the bottom. [8] Natural Rubber - The supply side: Yunnan has encountered cold weather, which has accelerated the end of the tapping season in Yunnan. The rainy season in southern Thailand continues, and the price of overseas raw materials is high, which strongly supports the rubber price. The demand side: Currently, the overall demand is weak. Channels are cautious in purchasing and mainly focus on digesting inventory. Next week, the purchasing enthusiasm of some agents on an as - needed basis may increase slightly, which will drive the overall sales volume. However, the overall demand is weakening, and the actual increase in purchasing volume is limited. The market still mainly focuses on digesting inventory. In conclusion, the natural rubber inventory has entered the seasonal inventory accumulation period, and the terminal demand support is insufficient. There is an expectation that the operating rate of downstream enterprises will further decline. It is expected that the natural rubber market will enter a range - bound consolidation. In the future, attention should be paid to the raw material output in the peak production season of the main producing areas and macro - level changes. If the raw material supply is smooth, the rubber price is expected to decline. If the raw material supply is not smooth, the rubber price is expected to operate in the range of 15,000 - 15,500. [9] Pure Benzene and Styrene - Pure benzene: Recently, many sets of pure benzene devices have overhaul expectations, but the import expectation remains high, and the overall supply may still be relatively loose. On the demand side, the load of downstream styrene has increased due to the restart of some devices, but some loss - making varieties have reduced production to maintain prices, and the domestic demand side has limited support. The port inventory has increased, and there are still many arrivals in the future, so the supply pressure of pure benzene is relatively large. After the overhaul of the disproportionation device in the US Gulf ends, the support from blending oil may weaken, but South Korea's aromatics have an export expectation to the US, and the US dollar price of pure benzene has increased. Overall, the supply - demand expectation of pure benzene is still relatively loose, and the limited support from the cost side may limit the upward space. It may fluctuate and consolidate. However, since the current valuation of pure benzene is low, future attention should be paid to device changes. In the short term, it is advisable to wait and see for BZ2603. - Styrene: After the overhaul of the disproportionation device in the US Gulf ends, the blending oil demand may weaken. However, in November, the supply - demand situation of styrene has further improved. With the South Korean mixed aromatics trading, styrene has an export transaction expectation, and the port inventory has decreased. There are positive factors supporting styrene, and it will mainly fluctuate and repair in the short term. However, as the profit of styrene is repaired, the overhaul of some factories may be delayed. Coupled with the trial operation of new devices and the expected weakening of downstream EPS demand, it is expected that the upward space of styrene will be limited. In the short term, the price of EB01 may mainly fluctuate and consolidate. [10] Polyester Industry Chain - PX: Recently, the operating loads of Asian and domestic PX have decreased. However, the supply of Asian MX is abundant, and some factories rely on MX to supplement PX production, so the PX supply still remains at a relatively high level. On the demand side, the PTA price still has certain support this week. However, the spot floating price and monthly spread of PX are still weak, and the overall support from oil prices is limited. It is expected that the rebound space of PX is limited. Strategically, PX should be regarded as a short - term high - level shock. - PTA: As two PTA devices in East China are gradually under maintenance, the basis has slightly strengthened. According to the balance sheet, the supply - demand of PTA is in a tight balance in November, but the supply - demand of PTA is expected to be relatively loose from December to the first quarter of next year, and the upward drive of the basis is limited. In terms of absolute price, recently, the absolute price of PTA is relatively strong due to the support of blending oil demand and India's cancellation of BIS certification. However, the overall support from oil prices is limited, and the rebound space of PTA is still limited. Strategically, TA should be regarded as a short - term high - level shock, and TA1 - 5 should be treated as a rolling reverse spread. - Ethylene glycol: The operating load of ethylene glycol is at a high level. The arrival of overseas ethylene glycol shipments is relatively concentrated in November, and the port inventory will continue to increase recently, and the basis will weaken. In addition, the inventory accumulation amplitude of ethylene glycol from November to December is expected to be relatively high, and the upward pressure on ethylene glycol is significant. Strategically, the seller of the out - of - the - money call option with an exercise price of no less than 4100 for EG2601 should hold, and EG1 - 5 should be reversely spread at high levels. - Short - fiber: Although the spot processing margin of short - fiber has been significantly compressed recently, there is still profit at present, and the inventory pressure of short - fiber factories is not large, so the short - fiber supply remains at a high level. On the demand side, the terminal demand has seasonally weakened in November. In addition, the cancellation of India's BIS certification has certain benefits for PTA and filament, but has relatively little impact on short - fiber. Therefore, under the short - term weak supply - demand expectation and cost - side support, it is expected that the absolute price of short - fiber will be under pressure, and the processing margin still has room for compression. Strategically, the unilateral strategy is the same as that of PTA; the processing margin on the disk should be shorted at high levels. - Bottle - grade polyester: In mid - November, the Huarun device has both maintenance and restart. In addition, according to Longzhong Information, the commissioning of the new device of Dongying Fuhai has been postponed, and the domestic supply has not changed much. Considering that November is in the off - season of demand and the window period between the Spring Festival stocking, the demand side has insufficient support for bottle - grade polyester. The supply - demand of bottle - grade polyester remains in a loose pattern. Therefore, the social inventory of bottle - grade polyester will probably enter the seasonal inventory accumulation channel, and PR will mainly fluctuate with the cost side. The processing margin of PR is limitedly boosted by supply - demand and will change dynamically with the raw material cost. Strategically, the unilateral strategy of PR is the same as that of PTA; the processing margin of the main contract of PR is expected to fluctuate in the range of 300 - 450 yuan/ton. [12] Crude Oil - Overnight, affected by the news that Russia and Ukraine may restart peace talks, the geopolitical premium has declined, and the oil price has declined under pressure. However, EIA data shows that the US crude oil inventory has decreased more than expected, and the decline of the oil price has been slightly narrowed. Recently, attacks or sanctions caused by the Russia - Ukraine issue have had a short - term impact on the oil price. However, under the pressure of continuous production increase by OPEC+ and the record - high US crude oil production, the supply - demand pattern of crude oil is still weak, and the upward pressure on the oil price is significant. In the short term, attention should be paid to the support of Brent crude oil at $60 per barrel and the geopolitical dynamics between Russia and Ukraine. [14] 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. Summary by Related Catalogs Polyolefins - **Prices and Spreads**: L2601, L2605, PP2601, and PP2605 prices decreased slightly. L15 and PP15 spreads increased.

Inventories of PVC and caustic soda decreased [14].

Report Industry Investment Ratings - No investment ratings were provided in the reports. Core Views Polyolefin Industry - PP shows both increasing supply and demand. Supply rises due to fewer maintenance shutdowns, and demand remains resilient in sectors like automotive and home appliances. However, there is a slight inventory build - up this week under the pressure of new production capacity. PE has weak supply and demand. Although unplanned maintenance eases supply pressure, imported goods are still abundant, and demand outside of agricultural films generally declines. There is overall insufficient support, and while inventory decreased this week, port inventory remains high. The cost side shows oil prices fluctuating and coal prices rising, with a slight improvement in PDH profits. High inventory and cost support continue to compete, and market expectations remain weak [2]. Methanol Industry - The Iranian gas restriction has been postponed. As of November 12th, Iran's shipments reached 430,000 tons, maintaining a relatively high level, putting significant pressure on the port methanol market. Prices and basis are weakly oscillating. In the inland market, Jiutai had an unexpected maintenance, but subsequent domestic production will continue to increase. Overseas gas restriction is less than expected. On the demand side, multiple MTO units reduced their loads due to profit reasons, and traditional downstream industries made rigid - demand purchases. The current market is trading under the "weak reality" logic, with the core contradiction being high port inventory. The inventory contradiction of the 01 contract cannot be resolved, and the weak reality will continue to be traded before the Iranian gas restriction [6]. Natural Rubber Industry - On the supply side, there are still occasional rainfall disruptions in overseas production areas, but overall, the output during the peak season is expected to be strong, and raw material prices have some downward space. The domestic production area is gradually entering the production - reduction period, and domestic raw material prices are firm. On the demand side, some northern regions are gradually entering the off - season this month, market sales are slowing down, and most companies are digesting inventory and purchasing as needed. As the market gradually digests inventory, some companies made small - scale replenishments in the middle of the month. In summary, short - term macro fluctuations are large, and rubber prices are expected to oscillate. In the future, attention should be paid to the raw material output in the peak - season of the main production areas and macro changes. If raw material supply is smooth, prices will be weak; if not, prices may be stable. It is expected that rubber prices will fluctuate around 15,000 - 15,500 [9]. Polyester Industry - **PX**: Asian and domestic PX loads remain high. In the short - term, PTA load is maintained, and previous terminal and polyester demand has improved more than expected. With low polyester inventory, it is expected that the load will remain relatively high from November to December, and there is still support on the short - term PX demand side. However, the overall support from the cost side is limited due to the weak supply - demand outlook for crude oil. Recently, the market has been trading on the expectations of PTA anti - involution and tight mid - term PX supply - demand. PX has shown a strong trend. But the terminal demand is entering the off - season, and there are concentrated PTA device maintenance plans in November, so the PX supply - demand outlook is loose, and price drivers are limited. Strategically, PX may oscillate in the range of 6,200 - 6,800 in the short - term, and short - selling can be considered above 6,800 [10]. - **PTA**: There are still many PTA device maintenance plans in November. Terminal and polyester demand has improved more than expected, and with low polyester inventory, it is expected that the load will remain relatively high from November to December. The PTA supply - demand is expected to be in a tight balance in November, but it is expected to be loose from February to the first quarter of next year. In terms of absolute price, the price driver is limited, and the support for PTA is limited. Although PTA - related stocks and absolute prices have been boosted by recent PTA production - cut rumors, the basis is still weakly operating. It is expected that the PTA rebound will be limited. Strategically, TA should be treated as oscillating in the range of 4,300 - 4,800 in the short - term, and short - selling on rallies is recommended; a rolling reverse spread for TA1 - 5 can be considered [10]. - **Ethylene Glycol**: Recently, some coal - based ethylene glycol plants have undergone maintenance, but Zhenhai Refining & Chemical's plant is restarting, and previously shut - down coal - based plants are planned to restart in the middle and late part of the month. Domestic supply remains high, and North American ethylene glycol load has increased to a high level, with no reduction in Middle - East supply. November will see a concentrated arrival of overseas ethylene glycol shipments. Although the polyester load is maintained above 91%, the expected high inventory build - up from November to December puts pressure on ethylene glycol prices. Strategically, hold out - of - the - money call options with a strike price of no less than 4,100 for EG2601; implement a reverse spread for EG1 - 5 on rallies [10]. - **Short - fiber**: Currently, short - fiber factories have low inventory levels and reasonable processing fees, so short - term supply remains relatively high. In terms of demand, there is an expectation of seasonal weakening in terminal demand in November. As raw material prices decline, short - fiber prices follow suit, and there has been some purchasing at low prices in the market. Overall, the short - term supply - demand pattern is still weak. Although there are expectations of PTA production cuts, the medium - term supply - demand weakness is difficult to change, and with the weak supply - demand outlook for upstream crude oil, price drivers are weak. It is expected that the rebound space for short - fiber is limited, and processing fees may be compressed. Strategically, the single - side strategy is the same as that for PTA; the processing fee on the futures market is expected to oscillate in the range of 800 - 1,100, and short - selling on rallies is recommended [10]. - **Bottle chips**: In mid - November, there are both maintenance and restart of the Huarun plant. According to Longzhong Information, the commissioning of Dongying Fuhai's new plant has been postponed, so there is little change in domestic supply. Considering the off - season market demand in November, the demand for soft drinks and catering has declined slightly, and the demand side provides insufficient support for bottle chips. The supply - demand situation for bottle chips remains loose. Therefore, bottle - chip social inventory is likely to enter the seasonal inventory - build - up phase. PR will mainly fluctuate with the cost side, and processing fees will be less boosted by supply - demand and will change dynamically with raw material costs. Strategically, the single - side strategy for PR is the same as that for PTA; the processing fee on the PR main - contract futures market is expected to fluctuate in the range of 300 - 450 yuan/ton [10]. Pure Benzene and Styrene Industry - **Pure Benzene**: Recently, there are new production capacities coming on - stream and plant restarts for pure benzene, and the import volume is expected to remain high. Although there are maintenance plans, overall supply may still be loose. On the demand side, some downstream industries are in the red, and the overall demand change is limited. Although the weekly inventory has decreased, the supply pressure remains. The overall supply - demand outlook for pure benzene is loose, and cost support is limited. Since the current valuation of pure benzene is low, future attention should be paid to plant changes. Strategically, BZ2603 has weak self - driving force and should be treated as short - selling on rallies following oil prices [11]. - **Styrene**: Two new styrene plants are operating stably, and previously shut - down plants have restarted, increasing production. There are still maintenance expectations in November, and overall supply may be maintained. The downstream EPS industry has entered the seasonal off - season, and due to high finished - product inventory, there are expectations of production cuts to maintain prices. Overall, the supply - demand outlook for styrene is in a tight balance, and price drivers are still insufficient. Attention should be paid to plant restarts, production cuts, and cost changes. Strategically, the price of EB12 should be treated as short - selling on rallies following cost changes [11]. LPG Industry - No overall view was provided in the report, only price, inventory, and开工率 data were presented [13]. Crude Oil Industry - Previously, due to the expectation that the US government shutdown would end soon and the strong performance of European diesel under continuous sanctions on Russia by Europe and the US, oil prices rebounded. However, the weak supply - demand pattern of crude oil still limits the increase. Overnight, on one hand, both OPEC and EIA monthly reports raised oil production forecasts, increasing concerns about supply over - capacity; on the other hand, there are signs of peace talks between Russia and Ukraine, and the geopolitical premium has declined. Overnight, oil prices dropped significantly. Under the continuous pressure of OPEC+ to increase production, the supply - demand outlook for crude oil in the fourth quarter is weak, and oil prices face pressure on rebounds. In the short - term, a bearish view is taken. Attention should be paid to the actual sanctions on Russia by Europe and the US and the geopolitical situation between Russia and Ukraine [16]. Summary by Directory Polyolefin Industry Price and Spread - Futures prices of L2601, L2605, PP2601, and PP2605 all increased slightly on November 12th compared to November 11th.
