Report Industry Investment Rating No relevant information provided. Core Viewpoints - Methanol: Current valuation is low, and the pattern will improve marginally next year. Although short - term downside risks remain, due to geopolitical instability in Iran, there is a feasibility of going long on dips [3]. - Urea: The current domestic - foreign price difference has opened the import window, and with the expected increase in production at the end of January, bearish fundamentals are coming, so take profits on rallies [6]. - Rubber: The current situation calls for a neutral approach and temporary observation. Partially close the hedging position of buying RU2605 and selling RU2609 [14]. - PVC: Fundamentally, the comprehensive corporate profit is at a historically low level, with short - term valuation pressure being small. However, supply reduction is limited, production is at a historical high, and domestic demand is in the off - season. In the short - term, strong sentiment drives a rebound, but in the medium - term, the strategy is to go short on rallies before significant industry production cuts [16]. - Pure Benzene & Styrene: Currently, the non - integrated profit of styrene is moderately low, with a large upward repair space for valuation. Before the first quarter of next year, it is advisable to go long on the non - integrated profit of styrene [19]. - Polyethylene: OPEC+ plans to suspend production growth in Q1 2026, and the crude oil price may have bottomed. The long - term contradiction has shifted from cost - induced decline to production mismatch. Go long on the LL5 - 9 spread on dips [22]. - Polypropylene: In the context of weak supply and demand, the overall inventory pressure is high. There is no prominent short - term contradiction. The futures price may bottom out when the supply - surplus pattern changes in Q1 next year [25]. - PX: Currently, the PX load remains high, and downstream PTA has many maintenance activities. Before the maintenance season, PX is expected to maintain a slight inventory build - up pattern. In the short - term, there is a large expected component in the market, so beware of correction risks. In the medium - term, look for opportunities to go long on dips [27]. - PTA: In the short - term, supply will maintain high - level maintenance. Demand for polyester and chemical fibers is under pressure, and due to the off - season, the load will gradually decline. After short - term inventory depletion, PTA will enter the Spring Festival inventory build - up stage. In the short - term, beware of corrections due to over - expectation, and in the medium - term, look for opportunities to go long on dips [30]. - Ethylene Glycol: The overall load is still relatively high. The port inventory build - up cycle will continue, and in the medium - term, there is an expectation of further profit compression and load reduction under the pressure of new device commissioning. Valuation needs to be compressed without further domestic production cuts [32].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The current spot price of caustic soda is stable with a slight decline. The supply side is operating at a high level, and the demand side shows weakening trends. The overall supply - demand situation is weak. The future focus is on changes in liquid chlorine prices, device dynamics, and the implementation of macro anti - involution details [3]. - The PVC market was weak in the early part of the month, rebounded due to macro - sentiment, and then the macro - sentiment faded, with the overall supply - demand situation remaining weak. It is expected to fluctuate in the near future, and attention should be paid to subsequent device maintenance and macro - side policies [6]. 3. Summary According to the Directory 3.1 Basis Strategy Analysis - **Caustic Soda**: The basis of caustic soda maintains a C - structure. The spot price first fell, then rose, and then fell again. The inventory is at a high level, and the basis is expected to continue to weaken. A reverse cash - and - carry strategy is recommended [12]. - **PVC**: The basis of PVC also shows a C - structure. After the price hit a new low, the supply - demand situation improved marginally, and the basis strengthened slightly. However, it is expected to weaken again in the future, and a reverse cash - and - carry strategy is recommended [12]. 3.2 Caustic Soda Price & Spread - In December, the spot price of caustic soda first fell, then rose, and then fell again. The high - level operation of production led to an oversupply situation and inventory accumulation. The demand from alumina is relatively stable, but the procurement price has been adjusted downward. Non - aluminum downstream demand enters the off - season in January [13]. 3.3 PVC Price & Spread - In December, the PVC price first fell and then rose. The high inventory led to a continuous decline in price, and the low price improved the supply - demand situation marginally. Macro - sentiment boosted the long - term demand expectation, but the overall supply - demand situation remained weak after the macro - sentiment faded [35]. 3.4 Cost and Profit - The comprehensive profit of chlor - alkali has been significantly reduced and is at a low level compared to the same period. The profit of PVC upstream raw materials is extremely compressed. The price of ethylene is expected to remain weak in January [52]. 3.5 Caustic Soda Supply - In December, new caustic soda production capacity was put into operation, and the overall supply remained at a high level. There are few planned maintenance enterprises in January, and the supply is expected to remain high due to the good market conditions of liquid chlorine [70]. 3.6 Liquid Chlorine Price and Its Downstream Products - In December, the price of liquid chlorine increased. The downstream demand supported the price, but in January, the terminal demand of some downstream products entered the off - season, and the price is expected to fluctuate slightly [82]. 3.7 PVC Supply - The overall PVC output remained high in December. All new production capacity has been put into operation, and the supply is still abundant. There is no new domestic production capacity in 2026, and the overseas supply contraction in December 2025 provided a small support to the market sentiment [98]. 3.8 Caustic Soda Downstream Demand - The demand from alumina is expected to weaken in the long - term. The non - aluminum downstream demand enters the off - season in January, and the demand of various industries is expected to decline seasonally [110]. 3.9 Caustic Soda Import and Export - The main import sources of domestic liquid caustic soda in November were Singapore, Norway, and Germany, and the main export destinations were Indonesia, Australia, and Canada. The export orders remain normal [132]. 3.10 PVC Downstream Demand - The downstream demand for PVC is weakening. The demand for pipes and profiles is affected by the sluggish real - estate market, while the film industry performs relatively well. The downstream demand is expected to decline further in January [145]. 3.11 PVC Import and Export - The BIS certification and anti - dumping duties of PVC in India have been cancelled, and the export expectation for 2026 is improving. The current PVC export maintains its resilience through price - for - volume strategy [156]. 3.12 Caustic Soda and PVC Inventory Data - The inventory of caustic soda increased in December due to factors such as production increase and weakening downstream demand. The PVC social inventory continued to increase, and the high - level futures warehouse receipts continued to suppress the PVC futures price [160].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Although the geopolitical premium has completely dissipated, OPEC's production increase is minimal. As the OPEC supply has not yet increased significantly, 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 when oil prices fall for verification [3]. - After the bullish factors are realized, the methanol market will enter a short - term consolidation. The inventory in ports will further decline due to reverse flow and trans - shipment. However, the import volume will remain high, and the olefin plants in ports have maintenance plans, so the port pressure still exists. The overall supply is at a high level, and the methanol fundamentals still face some pressure, with the price expected to consolidate at a low level. It is recommended to wait and see for unilateral trading [4]. - The urea market is showing signs of improvement in supply - demand balance. The reserve demand and the increase in compound fertilizer production have boosted short - term demand, and the supply is expected to decline seasonally. With export policy and cost support, the downside space is limited, and it is expected to build a bottom through oscillation. It is advisable to consider buying at low prices [7]. - The natural rubber market has different views from bulls and bears. Bulls are optimistic due to seasonal expectations and demand prospects, while bears are pessimistic because of weak demand. Currently, it is recommended to adopt a neutral approach, wait and see, and partially close the hedging position of buying RU2605 and selling RU2609 [9][10]. - The PVC market has low valuation pressure in the short term, but the supply reduction is small, and the production is at a historical high. The domestic demand is in the off - season, and although the Indian BIS policy has been revoked and there is no expected anti - dumping tax, there is still off - season pressure. In the context of strong supply and weak demand, it is advisable to short on rallies in the medium term [14]. - The non - integrated profit of styrene is moderately low, and there is significant room for valuation repair. The cost - side pure benzene supply is still abundant, and the styrene production is increasing. The styrene port inventory has been accumulating, and the demand is in the off - season. It is advisable to go long on non - integrated styrene profit before the first quarter of next year [17]. - For polyethylene, OPEC+ plans to suspend production growth in the first quarter of 2026, and the crude oil price may have bottomed out. The spot price of polyethylene has increased, and the inventory is expected to decline from a high level.

It is expected to enter the inventory - building stage during the Spring Festival after short - term inventory reduction. The valuation has room to increase in the coming year, but attention should be paid to the callback risk in the short term. It is advisable to go long at low prices in the medium term [28]. - The ethylene glycol industry has a high overall load, and the port inventory - building cycle will continue. Although the overseas unexpected maintenance has increased, the domestic reduction is insufficient. The valuation is moderately low year - on - year, and the valuation may need to be compressed without further domestic production cuts in the medium term [30].

1. Report Industry Investment Rating No relevant information provided. 2. Core Views of the Report - For crude oil, although the geopolitical premium has disappeared 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 is recommended to wait and see for now to verify OPEC's export price - support willingness [2]. - For methanol, after the bullish factors are realized, the market will enter a short - term consolidation. The port inventory will continue to decline, but there are still pressures in the future due to high imports and potential port olefin plant overhauls. The methanol fundamentals have some pressure, and it is expected to consolidate at a low level. It is recommended to wait and see for unilateral strategies [3]. - For urea, the market continues to oscillate higher. The demand has improved in the short term, and the supply is expected to decline seasonally. The overall supply - demand situation has improved, and it is expected to build a bottom in an oscillatory manner. It is recommended to consider buying on dips [7]. - For rubber, currently having a neutral - to - bullish view, short - term operations with quick entries and exits are recommended. It is suggested to hold the hedging position of buying RU2601 and shorting RU2609 [12]. - For PVC, the fundamentals are poor with strong domestic supply and weak demand. The short - term sentiment drives a rebound, but in the medium term, a strategy of shorting on rallies is recommended before significant industry production cuts [14]. - For pure benzene and styrene, the non - integrated profit of styrene is neutral to low, and there is a large upward repair space for valuation. 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.

Group 1: Natural Rubber Industry Report Industry Investment Rating Not mentioned in the report. Core View Supply - side, geopolitical tensions in Thailand and Cambodia have not eased, affecting local raw material supply, and domestic production areas are accelerating the suspension of production, so there is still support at the bottom of rubber prices. Demand - side, the resumption of work of maintenance enterprises will support overall capacity utilization, but enterprises will maintain production control in the short - term due to rising production and sales pressure. Market - side, considering the achievement of annual tasks, some agents still have moderate replenishment behavior, but it is the seasonal off - season, and actual market transactions are mainly for just - in - time needs. The market will continue to run weakly.
