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 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 low - buy and high - sell range strategy is maintained, but it is recommended to wait and see for now to verify OPEC's export price - support intention when oil prices fall [2]. - For methanol, after the bullish factors are realized, the market is in short - term consolidation. With high import arrivals and potential port olefin plant maintenance, there is still pressure on the port. The supply is at a high level, and the fundamentals have some pressure. It is expected to consolidate at a low level, and a wait - and - see approach is recommended for single - side trading [4]. - For urea, the market is oscillating higher. Demand has improved in the short term, and supply is expected to decline seasonally. The overall supply - demand situation has improved, and there is support at the bottom.

The fundamentals are poor, and a short - selling strategy on rallies is recommended before substantial production cuts in the industry [15]. - For pure benzene and styrene, when the inventory reversal point appears, it is advisable to go long on the non - integrated profit of styrene [19]. - For polyethylene, the long - term contradiction has shifted from cost - driven decline to production mismatch. It is recommended to short the LL1 - 5 spread on rallies [22]. - For polypropylene, in the context of weak supply and demand with high inventory pressure, it may be supported when the supply - surplus pattern in the cost side changes in the first quarter of next year [25]. - For PX, it is expected to have a slight inventory build - up in December. Attention should be paid to the opportunity of going long on dips [28]. - For PTA, the supply is expected to stabilize, and the demand is likely to maintain a high level in the short term. It is recommended to look for long - buying opportunities on dips based on expectations [29]. - For ethylene glycol, the supply - demand pattern is expected to be weak in the medium term.
