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 range - trading strategy of buying low and selling high is maintained, but it's advisable to wait and see for now to verify OPEC's export price - support intention [3]. - For methanol, after the bullish factors are realized, the market enters a short - term consolidation. With high import arrivals and potential port olefin plant maintenance, there is still pressure on the port. The overall supply is high, and the market is expected to consolidate at a low level. It is recommended to wait and see [6]. - For urea, the market is oscillating upwards. The demand has improved due to reserve needs and increased compound fertilizer production. Supply is expected to decline seasonally. With support from export policies and costs, it is expected to build a bottom through oscillation. It is recommended to consider buying on dips [8]. - For rubber, a neutral - bullish approach is currently adopted. It is recommended to buy on short - term dips and exit quickly. A hedging position of buying RU2601 and selling RU2609 is suggested to be held [13]. - For PVC, the industry's comprehensive profit is at a historical low, but supply is high and demand is weak. With an oversupply situation, it is recommended to short on rallies [16]. - 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 a situation of weak supply and demand with high inventory pressure, it may be supported by cost changes in Q1 next year [25]. - For PX, it is expected to slightly accumulate inventory in December. With a neutral valuation, it is recommended to consider going long on dips [26]. - For PTA, the supply is expected to stabilize, and the demand may maintain a high level in the short term. It is recommended to consider going long on dips based on expectations [27]. - For ethylene glycol, the supply - demand pattern is expected to be weak in the medium term. It is recommended to short on rallies in the medium term [29]. 3.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Although the geopolitical premium in the oil market has completely dissipated and OPEC has increased production in a very limited amount, and OPEC's supply has not yet increased significantly, so it is not advisable to be overly bearish on oil prices 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 as verification [3]. - For methanol, the potential bullish factors from the previous shutdown in Iran have started to materialize. The market has stopped falling and stabilized, with the futures price rising on reduced positions and the monthly spread starting to recover from the bottom. It is expected that a short - term bottom has emerged. In the future, supply is expected to remain at a high level, limiting the upward space for methanol. It is expected that the market will gradually shift to a sideways adjustment after the bullish factors are realized. It is advisable to wait and see on the single - side trading and focus on positive spread opportunities for the monthly spread [5]. - For urea, the futures price has been oscillating higher, and the spot price has rebounded from the bottom. With low valuations, the downside space for urea is relatively limited, and prices are expected to gradually move out of the bottom range. In the future, attention should be paid to export and off - season storage demand on the demand side, and winter gas - based shutdowns and cost support on the supply side. At low prices, it is recommended to consider buying on dips [7]. - For rubber, currently adopt a neutral approach. It is recommended to wait and see or conduct short - term quick - in and quick - out trading. Partially build positions for the hedging strategy of buying RU2601 and selling RU2609 [12]. - For PVC, fundamentally, the comprehensive profit of enterprises remains at a low level for the year, and the valuation pressure is relatively small in the short term. However, the supply side has few maintenance operations, and production is at a historical high. Multiple new plants are expected to start trial production in the short term. The domestic demand is about to enter the off - season, and the demand side is under pressure. Although exports to India are expected to remain high, it is still difficult to digest the excess production capacity. In the medium term, before the industry substantially reduces production, it is advisable to adopt a strategy of shorting on rallies [14]. - For pure benzene and styrene, currently, the non - integrated profit of styrene is moderately low, and there is a large space for valuation repair. When the inventory reversal point appears, one can go long on the non - integrated profit of styrene [17]. - For polyethylene, OPEC+ has announced plans to suspend production growth in Q1 2026, and the crude oil price may have bottomed out. The spot price of polyethylene remains unchanged, and the downward space for PE valuation is limited. In the long term, the contradiction has shifted from cost - driven downward trends to production mismatch. It is advisable to short the LL1 - 5 spread on rallies [20]. - For polypropylene, in a background of weak supply and demand, the overall inventory pressure is high, and there are no prominent short - term contradictions. When the oversupply situation on the cost side changes in Q1 next year, it may provide some support to the futures price [23]. - For PX, currently, the PX load remains at a high level, while downstream PTA has many maintenance operations and the overall load center is low. It is expected that PX will experience a slight inventory build - up in November. There is a risk of a slight valuation correction [24]. - For PTA, in the future, on the supply side, as processing fees gradually stabilize and recover, unexpected maintenance is expected to gradually decrease. On the demand side, the inventory and profit pressure of polyester fiber are relatively low, and the load is expected to remain high in the short term. However, due to inventory pressure and the approaching off - season for bottle chips, it is difficult for the load to increase. There is a risk of a slight valuation correction for PXN [25]. - For ethylene glycol, on the industrial fundamentals, the domestic plant load is lower than expected due to a large number of unexpected maintenance operations. The domestic supply is expected to decline in December, and the import volume will decrease slightly. The inventory build - up rate at ports may slow down. In the medium term, as maintenance ends, domestic production is still expected to be high, and with new plants gradually coming into operation, the supply - demand situation is expected to remain weak. It is recommended to short on rallies in the medium term [27].
