It is advisable to go long on the non - integrated profit of styrene before the first quarter of next year [17]. - For polyethylene, OPEC +'s plan to suspend production growth in Q1 2026 may lead to a bottoming of crude oil prices. The valuation of PE has limited downward space. It is recommended to go long on the LL5 - 9 spread on dips [20]. - For polypropylene, in a situation of weak supply and demand with high inventory pressure, there is no prominent contradiction in the short term. It may be supported when the supply - surplus pattern of the cost side changes in Q1 next year [22]. - For PX, the load remains high, and downstream PTA has many overhauls. It is expected to have a slight inventory build - up in December. It is advisable to pay attention to buying on dips [25]. - For PTA, the supply will maintain high - level overhauls in the short term, and the demand will gradually decline due to the off - season. The processing fee has limited upward space. It is recommended to pay attention to buying on dips based on expectations [27]. - For ethylene glycol, the overall load is still high, and the port inventory build - up cycle will continue. The valuation is neutral to low. Attention should be paid to the risk of a balance - sheet reversal caused by increased unexpected overhauls [29]. 3.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports - **Natural Rubber**: With geopolitical tensions affecting supply in Thailand and domestic产区 entering the off - season, there is support at the bottom of rubber prices. However, due to high production and sales pressure and the seasonal demand slump, the market is weak. Rubber prices are expected to fluctuate widely between 15,000 - 15,500 yuan/ton [1]. - **Glass and Soda Ash**: For soda ash, the supply may increase with the potential output from new projects, and demand is shrinking, so the price is expected to continue to decline with occasional technical rebounds. For glass, the spot price is stable but facing weakening demand in the north and high inventory in the middle - stream, so the futures price may be under pressure and continue to oscillate at the bottom [3]. - **PVC and Caustic Soda**: The caustic soda industry still has supply - demand pressure, and prices are expected to be weak. The PVC market is affected by high supply, low demand, and cost pressure, and is expected to maintain range - bound trading and then weaken after a rebound [4]. - **Polyolefins**: The market is trading on the expectation of high production in 2026 and weak current conditions. Both PE and PP are facing downward pressure on prices, with the price center expected to decline further [6]. - **Methanol**: Although the port may face inventory accumulation in December, there is an expected shift to inventory reduction in the first quarter of the next year. The inland market is expected to be stable with prices fluctuating slightly [10]. - **Pure Benzene and Styrene**: The short - term driving force for pure benzene is weak due to weak downstream demand and cost support, but there is an expectation of improvement after the spring maintenance. Styrene is expected to oscillate between 6300 - 6700 yuan/ton due to sufficient supply and weak cost support [13]. - **LPG**: The LPG market shows a pattern of stable prices, inventory reduction, and some improvement in downstream demand. The price is expected to be relatively stable with some fluctuations [15]. - **Polyester Industry Chain**: For PX, it may continue to be strong unless there is substantial production reduction in the polyester sector.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Although the geopolitical premium has completely dissipated and OPEC has increased production in a very limited amount, and OPEC's supply has not yet increased significantly, so oil prices should not be overly bearish in the short term. Maintain a range strategy of buying low and selling high for oil prices, but currently, oil prices need to test OPEC's willingness to support prices through exports. It is recommended to wait and see in the short term and wait for a decline in OPEC exports to confirm when oil prices fall [2]. - After the bullish factors are realized, the methanol market has entered a short - term consolidation. The port inventory has further decreased due to port back - flow and trans - shipment. However, the import arrivals will remain high, and the port olefin plants have maintenance plans. The overall supply is at a high level, and the methanol fundamentals still face some pressure. It is expected to consolidate at a low level, and a unilateral strategy of waiting and seeing is recommended [4]. - The urea market has continued to rise in a volatile manner. The reserve demand and the increase in compound fertilizer production have led to an improvement in short - term demand. The supply is expected to decline seasonally. The overall supply - demand situation of urea has improved, and there is support from export policies and costs. It is expected to build a bottom in a volatile manner. It is recommended to consider buying on dips [7]. - For rubber, a neutral approach is currently adopted, and short - term operations with quick entry and exit are recommended. Holding a hedging position of buying RU2601 and selling RU2609 is advised [12]. - The PVC market has a poor fundamental situation. The domestic supply is strong while the demand is weak, and it is difficult to reverse the oversupply situation. Although there is a short - term rebound driven by sentiment, in the medium term, a strategy of shorting on rallies is recommended before there is a substantial reduction in industry production [14]. - For pure benzene and styrene, the non - integrated profit of styrene is neutral to low, and there is a large space for valuation repair. The supply of pure benzene is still abundant, and the port inventory of styrene has been continuously decreasing. It is recommended to go long on the non - integrated profit of styrene before the first quarter of next year [17]. - For polyethylene, although the PE valuation has limited downward space, the high number of warehouse receipts in the same period of history suppresses the market. The overall inventory is at a high level but is decreasing. It is recommended to go long on the LL5 - 9 spread on dips [20]. - For polypropylene, under the background of weak supply and demand, the overall inventory pressure is high. There is no prominent contradiction in the short term. It is expected that the supply - surplus situation at the cost end will change in the first quarter of next year, which may support the market [23]. - For PX, it is expected to have a slight inventory build - up in December. The current valuation is at a neutral level, and opportunities to go long on dips are worth paying attention to [26]. - For PTA, the supply will maintain a high level of maintenance in the short term, and the demand will gradually decline due to the off - season. The PTA processing fee has limited upward space in the short term. Opportunities to go long on dips based on expectations are recommended [28]. - For ethylene glycol, the domestic supply has improved due to unexpected maintenance, but the overall load is still high, and the port inventory is in a build - up cycle. There is a risk of a rebound due to further increases in maintenance.

It is expected to consolidate at a low level, and a unilateral strategy of waiting and seeing is recommended [4]. Urea - **Market Information**: Regional spot prices in Shandong changed by 20 yuan/ton, in Henan by 10 yuan/ton, in Hebei by 10 yuan/ton, in Hubei by 0 yuan/ton, in Jiangsu by 20 yuan/ton, in Shanxi by 20 yuan/ton, and in the Northeast by 0 yuan/ton. The total basis was reported at - 17 yuan/ton. The main futures contract changed by - 11 yuan/ton, reporting 1697 yuan/ton [6]. - **Strategy**: The urea market has continued to rise in a volatile manner. The reserve demand and the increase in compound fertilizer production have led to an improvement in short - term demand. The supply is expected to decline seasonally. The overall supply - demand situation of urea has improved, and there is support from export policies and costs. It is expected to build a bottom in a volatile manner. It is recommended to consider buying on dips [7]. Rubber - **Market Information**: The rubber price has been consolidating. The exchange's RU inventory warrants are at a low level, and the buying demand for winter storage is a bullish factor. The bulls believe in seasonal expectations and improved demand, while the bears are concerned about macro uncertainties and weak demand. As of December 18, 2025, the operating rate of all - steel tires in Shandong tire enterprises was 64.66%, up 1.08 percentage points from last week and 2.56 percentage points from the same period last year. The operating rate of semi - steel tires in domestic tire enterprises was 72.76%, down 0.24 percentage points from last week and 5.93 percentage points from the same period last year. The inventory of semi - steel tires has increased. As of December 14, 2025, the total social inventory of natural rubber in China was 115.2 tons, a 2.6% increase from the previous month [10][11]. - **Strategy**: A neutral approach is currently adopted, and short - term operations with quick entry and exit are recommended. Holding a hedging position of buying RU2601 and selling RU2609 is advised [12]. PVC - **Market Information**: The PVC05 contract fell 56 yuan, reporting 4652 yuan. The spot price of Changzhou SG - 5 was 4400 (- 30) yuan/ton, the basis was - 252 (+ 26) yuan/ton, and the 5 - 9 spread was - 129 (+ 1) yuan/ton. The overall PVC operating rate was 77.4%, a 2.1% decrease from the previous period. The demand - side overall downstream operating rate was 45.4%, a 3.5% decrease from the previous period. The factory inventory was 32.9 tons (- 1.6), and the social inventory was 105.7 tons (- 0.3) [12]. - **Strategy**: The PVC market has a poor fundamental situation. The domestic supply is strong while the demand is weak, and it is difficult to reverse the oversupply situation. Although there is a short - term rebound driven by sentiment, in the medium term, a strategy of shorting on rallies is recommended before there is a substantial reduction in industry production [14]. Pure Benzene and Styrene - **Market Information**: The spot price of pure benzene in East China was 5275 yuan/ton, unchanged. The closing price of the active pure benzene contract was 5394 yuan/ton, unchanged. The pure benzene basis was - 119 yuan/ton, narrowing by 13 yuan/ton.

Group 1: Investment Ratings - No investment ratings provided in the reports Group 2: Core Views Polyolefins (LLDPE & PP) - The fundamentals of both LLDPE and PP show a pattern of increasing supply and weakening demand, with cost support and inventory pressure coexisting. Polypropylene has high maintenance levels on the supply - side with an expected increase later, and its inventory is still higher than usual. The overall valuation is moderately low. For polyethylene, the operating load is gradually rising, and the upstream inventory is still high year - on - year [1]. Methanol - The methanol futures fluctuated upwards, with the basis being relatively firm. In the port area, Iranian gas restrictions led to multiple device shutdowns, but shipments are still fast. In the inland area, both supply and demand are increasing. It is recommended to go long on the 05 contract at low prices after the shipment decreases [4][5]. PVC & Caustic Soda - For caustic soda, the supply - demand situation still has pressure, with high inventory levels. The price is expected to be weak. For PVC, the supply pressure remains this week, and the demand is sluggish.

It is recommended to go short on PVC after a rebound [8]. Glass & Soda Ash - For soda ash, the supply - demand situation is bearish, and the price is in a downward trend. After a technical rebound, short - term long positions can be closed, and short positions can be taken after a rebound. For glass, the spot price is stable, but the demand is weakening, and the price is expected to be under pressure, with the 01 contract following the delivery logic and the 05 contract remaining weak in the short - term [9]. Polyester Industry Chain - PX may fluctuate in the range of 6600 - 7000 in the short - term and should be treated with low - buying. PTA may fluctuate in the range of 4500 - 4800 in the short - term, and low - buying and TA5 - 9 low - level positive spreads are recommended. Ethylene glycol is expected to oscillate at a low level in the short - term, and it is recommended to sell EG2605 - C - 4100 to obtain time value. Short - fiber follows the raw material fluctuations, and the processing fee on the disk should be shorted when it is high. For polyester bottle - chips, it is recommended to sell PR2602 - P - 5500 [11]. Natural Rubber - The supply - side is supported by rising overseas raw material prices due to the tense situation between Thailand and Cambodia. The demand - side has limited improvement in production capacity utilization. The market is in a short - term stalemate between long and short forces, and the rubber price is expected to oscillate in the range of 15000 - 15500 [13]. Urea - Affected by the news of India's new round of tenders, the urea price stopped falling and rebounded. The supply is abundant, and the demand is weak.

1. Report Industry Investment Rating No relevant content 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 low - buy and high - sell range strategy is maintained, but it's advisable to wait and see for now to verify OPEC's export price - support willingness [1]. - For methanol, after the bullish factors are realized, the market enters a short - term consolidation. With port inventory depletion and high expected imports and potential port olefin plant maintenance, the fundamentals face pressure, and a wait - and - see approach is recommended for single - side trading [2][3]. - For urea, the market is oscillating higher. With improving demand from reserves and compound fertilizer production, and a seasonal decline in supply, the overall supply - demand situation is improving. It is expected to bottom out in an oscillatory manner, and a low - price long - position strategy is recommended [5][6][7]. - For rubber, a neutral - bullish short - term trading strategy is suggested, and a hedging position of buying RU2601 and selling RU2609 is recommended [9][10]. - For PVC, the industry has low comprehensive profit, high supply, and weak demand. In the short - term, sentiment drives a rebound, but in the medium - term, a short - selling strategy on rallies is recommended [10][12]. - For pure benzene and styrene, the non - integrated profit of styrene is neutral - low with large upward valuation repair space. It is advisable to go long on non - integrated styrene profit before the first quarter of next year [13][14]. - For polyethylene, the PE valuation has limited downward space, but high - level warehouse receipts suppress the market. A strategy of narrowing the LL1 - 5 spread on rallies is recommended [16][17]. - For polypropylene, in a supply - demand weak situation with high inventory pressure, the market may be supported when the supply - surplus situation at the cost end changes in the first quarter of next year [18][19]. - For PX, it is expected to accumulate a small amount of inventory in December. A long - position strategy on dips is recommended [21][22]. - For PTA, the supply may increase and demand may decline in the future. A long - position strategy on expected trading on dips is recommended [23][24]. - For ethylene glycol, the industry needs to increase production cuts to improve the supply - demand situation. There is a risk of a rebound due to unexpected maintenance [25][26]. 3.
