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. Although there are expectations of increased exports, the overall supply - demand is in an oversupply situation, and the price is not optimistic. 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. The price is expected to bottom - out and rebound in the short - term, fluctuating in the range of 1650 - 1700 [15]. Crude Oil - After a rebound, the crude oil price is affected by geopolitical factors such as the situation between the US and Venezuela and the US - Russia talks. The inventory shows a slight reduction, but the supply - demand pattern is still loose. Brent crude oil should be monitored at the level of 60 dollars per barrel [16]. Pure Benzene & Styrene - For pure benzene, the short - term supply - demand is weak, but there are expectations of improvement later. It is expected to oscillate in the range of 5300 - 5600. For styrene, the supply is increasing, the demand is weak, and it is expected to oscillate in the range of 6400 - 6700 in the short - term [19]. LPG - The LPG price shows certain fluctuations.

Report Industry Investment Rating - Not provided Core Viewpoints - The Central Financial and Economic Work Conference determined the economic direction. With the improvement of market sentiment boosted by macro - policies, the polyolefin market stopped falling and rebounded. However, the current weak supply - demand fundamentals provide insufficient support for prices [3]. - For PE, the supply is expected to be loose and the demand is weak, with high inventory pressure and limited oil - based cost support. The short - term fundamentals are difficult to be substantially boosted, and the rebound space is limited [3]. - For PP, the supply is expected to remain high, the demand follow - up is insufficient, the inventory level is high, and the cost support is weakened. The short - term rebound drive is limited, and attention should be paid to cost and supply changes [4].

Strategy - **Unilateral**: Wait and see [5]. - **Inter - period Spread**: Go long on the L05 - 09 inter - period spread when it is low; go long on the PP05 - 09 inter - period spread when it is low [5]. - **Inter - variety Spread**: Short the L05 - PP05 spread when it is high [5].

Report Industry Investment Rating No relevant content provided. 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, oil prices should not be overly shorted in the short - term. A low - buy and high - sell range strategy is maintained, but it's advisable to wait and see for now to test OPEC's export price - support willingness [2]. - For methanol, after the bullish factors are realized, the market enters short - term consolidation. With high import arrivals and expected port olefin plant maintenance, there is still pressure on the port. The supply is at a high level, and the market is expected to consolidate at a low level. A wait - and - see approach is recommended for single - side trading [3]. - For urea, the market is rising in a volatile manner. Demand has improved in the short - term due to reserve needs and increased compound fertilizer production. 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 in a volatile manner. Buying on dips is recommended [6]. - For rubber, a neutral approach is taken, suggesting short - term operations. Holding a hedging position of buying RU2601 and selling RU2609 is advised [12]. - For PVC, the enterprise's comprehensive profit is at a historical low, but supply reduction is limited, and demand is under pressure. With strong supply and weak demand in the domestic market, shorting on rallies is recommended before significant industry production cuts [13][15]. - For pure benzene and styrene, when the inventory reversal point appears, going long on the non - integrated profit of styrene can be considered. Currently, styrene's non - integrated profit is neutral to low, with potential for upward valuation repair [18]. - For polyethylene, OPEC +'s plan to suspend production growth in Q1 2026 may lead to a bottoming of oil prices. With high inventory and seasonal demand decline, shorting the LL1 - 5 spread on rallies is recommended [21]. - For polypropylene, with expected supply surplus in the cost side and high inventory pressure, the market may be supported when the supply - surplus pattern changes in Q1 next year [24]. - For PX, it is expected to slightly accumulate inventory in December. With a neutral valuation, opportunities for going long on dips can be considered [27]. - For PTA, supply maintenance is expected to decrease, and demand will decline due to the off - season. With limited upside for processing fees, opportunities for going long on expected trading can be watched [29]. - For ethylene glycol, although domestic supply has improved due to unexpected maintenance, overall load is still high, and ports are in a inventory - accumulation cycle. Attention should be paid to the risk of a rebound caused by increased maintenance [31].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - In the short - term, the domestic pure benzene has a large real - time arrival pressure, with port inventory accelerating accumulation. The overseas gasoline shortage has passed, but the price difference between the US and South Korea in the pure benzene market is still being repaired. Downstream提货 is weak, and downstream开工 is further decreasing in the off - season. Styrene maintains low - load maintenance, CPL开工 drops to the lowest level of the year, phenol开工 rebounds, and aniline and adipic acid开工 fluctuate within a range [3]. - For styrene, port inventory further declines, and the port basis remains strong. Styrene maintains low - level operation, port inventory continues to decrease, and downstream提货 is acceptable. The downstream开工 shows differentiation. EPS开工 rebounds slightly in the off - season but still has inventory pressure; ABS开工 decreases due to continuous finished - product inventory pressure; PS开工 continues to rise at the end of the year as the finished - product inventory pressure eases [3].
