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 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]. LPG - There is no clear view statement in the report, but data shows that LPG futures prices have risen, while the spot price in South China has fallen. Inventory has increased, and the operating rates of some upstream and downstream industries have changed [16]. 3.

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]. Crude Oil Industry The short - term oil price is expected to fluctuate within a range, with Brent crude oil likely to trade between 60 - 66 dollars per barrel [10]. Pure Benzene and Styrene Industry - Pure Benzene: The supply - demand is expected to be loose, and the price driver is weak. Short - term BZ2603 should be treated as short on rallies following the oil price [14]. - Styrene: The supply - demand may turn loose, and the price driver is insufficient. EB12 should be shorted on price rebounds [14]. 3.
