1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints 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 range - trading strategy of buying low and selling high is maintained, but it's advisable to wait and see for now to verify OPEC's export price - support willingness when prices fall [2]. - For methanol, the futures market continues to decline weakly. High port inventory pressure persists, with limited destocking before the 01 contract. Supply remains high while demand shows little change. The market is trading on the weak - reality logic, and prices may further decline [3]. - For urea, prices are oscillating and rising from the bottom, showing relative resilience. Supply - side corporate profits are low, and production has slightly declined but is still high year - on - year. Demand has improved due to agricultural reserves and exports. With export policies and cost support, the downside is limited, and it's expected to oscillate and build a bottom, suggesting buying on dips [6][8]. - For rubber, the start - up load of tire enterprises has decreased, and semi - steel tire export orders have slowed. However, typhoons may increase supply, and the cancellation of warehouse receipts may benefit the January contract. Arbitrage strategies include going long on RU2601 and short on RU2609 or NR [10]. - For PVC, corporate profits are at a low level, supply is high with new installations coming online, and demand is weak both domestically and in exports. There is a risk of continuous inventory accumulation, and it's advisable to short on rallies in the medium term [12]. - For pure benzene and styrene, pure benzene prices are stable, while styrene prices are rising. Supply is under pressure, but the BZN spread has room to recover. Port inventory is decreasing, and prices may stop falling in the short term [15]. - For polyethylene, OPEC +'s plan to pause production growth may support oil prices. PE valuation has limited downside, but high warehouse receipts suppress the market. With inventory reduction and seasonal demand, prices may oscillate at a low level [18]. - For polypropylene, cost - side supply may increase, and supply pressure remains high. Although demand has rebounded seasonally, overall inventory pressure is high. Prices may be supported when the supply - surplus situation changes in Q1 next year [20]. - For PX, the load is high, but downstream PTA maintenance is frequent, leading to expected inventory accumulation in November. However, there is support from aromatics blending and long - term supply - demand structure, and there may be opportunities for valuation increase in the medium term [23]. - For PTA, supply - side maintenance has increased, but new installations will lead to inventory accumulation in November. Demand may remain high, but there is limited room for improvement. PTA processing fees are under pressure, but it may strengthen when PXN rises in the medium term [25]. - For ethylene glycol, domestic and overseas installations are operating at high loads, imports are increasing, and inventory is accumulating. Valuation is relatively low, and it's advisable to short on rallies [28]. 3.

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 Rating There is no information provided regarding the report industry investment rating. 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 range strategy of buying low and selling high is maintained, but it's advisable to wait and see to verify OPEC's export price - support intention [2]. - For methanol, high port inventories suppress prices. Overseas production remains high, and with coal prices strong and enterprise profits falling, supply pressure persists. Demand is weak, so prices may decline further, and it's recommended to wait and see [3]. - For urea, the market is sensitive to news. Domestic demand lacks support, and supply is high. New export policies have improved the market atmosphere, and inventories are decreasing. Urea prices are expected to bottom out with limited downside [6]. - For rubber, the current view is bullish. Short - term bullish trading with quick in - and - out is recommended, and partial position - building for the hedge of buying RU2601 and selling RU2609 is advised [9]. - For PVC, the fundamentals are poor. Supply is strong, demand is weak, and export expectations are weakening. It's recommended to consider short - selling on rallies in the medium term [10]. - For pure benzene and styrene, the BZN spread has room to recover. Port inventories are decreasing, and styrene prices may stop falling temporarily [14]. - For polyethylene, the price may remain in a low - level oscillation. The cost - driven decline may shift to the impact of South Korea's ethylene clearance policy [17]. - For polypropylene, in a weak supply - demand situation with high inventory pressure, the price may be supported when the supply - surplus situation of the cost side changes in Q1 next year [19]. - For PX, it is expected to accumulate a small amount of inventory in November, but there is support from aromatics blending for gasoline and the long - term supply - demand structure. Mid - term valuation increase opportunities are worth attention [22]. - For PTA, it is expected to accumulate inventory in November. Although polyester load may remain high, PTA processing fees are under pressure. Pay attention to the opportunity of PTA strengthening driven by the increase of PXN in the medium term [24]. - For ethylene glycol, inventories are expected to accumulate in Q4. With a weak pattern, the valuation may be further compressed, and short - selling on rallies is recommended [27]. 3.
