1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report - For crude oil, although the geopolitical premium has dissipated and OPEC's production increase is minimal with supply not yet expanding, short - term oil prices should not be overly bearish. A range - trading strategy of buying low and selling high is maintained, but the current oil prices need to test OPEC's export price - support willingness, and short - term wait - and - see is recommended [3]. - For methanol, high port inventories suppress prices. Overseas开工 remains high, arrivals are at a high level, and port inventories are rising. Coal prices are strong, squeezing enterprise profits and causing a slight decline in enterprise开工. Demand is weak overall, and there is a risk of price decline, so it is recommended to wait and see [6]. - For urea, the market is sensitive to bullish news. Domestic demand lacks support, and supply is high. New export policies improve the market atmosphere, and inventories are being depleted at a high level. The downside space is relatively limited, and it is expected to bottom out through oscillations [9]. - For rubber, a neutral approach is adopted, and short - term trading with quick entry and exit is recommended. A partial position can be established for the hedging strategy of buying RU2601 and selling RU2609 [13]. - For PVC, the enterprise's comprehensive profit is at a low level, but supply is high, and new devices are about to be put into operation. Demand is under pressure, and export prospects are poor. There is a risk of inventory accumulation, and short - term valuation is low. A short - selling strategy on rallies can be considered in the medium term [15]. - For pure benzene and styrene, the BZN spread has room for upward repair. Port inventories are being depleted, and styrene prices may stop falling in the short term [18]. - For polyethylene, OPEC +'s plan to suspend production growth may lead to a bottoming of crude oil prices. Polyethylene's valuation has limited downward space, but high - level warehouse receipts suppress the market. Supply is limited, and demand is picking up seasonally. Prices are expected to oscillate at a low level [21]. - For polypropylene, the cost side sees a potential increase in global oil inventories, and supply pressure is high. Demand is picking up slightly, and overall inventories are high. There is no prominent short - term contradiction, and prices may be supported in Q1 2026 [24]. - For PX, it is expected to see a slight inventory build - up in November, but there is support from aromatics blending into gasoline and the long - term supply - demand structure. Pay attention to the opportunity of mid - term valuation increase [27]. - For PTA, supply is expected to increase with new device launches, and inventories are expected to accumulate in November. Demand is expected to remain high but has limited room for improvement. Pay attention to the opportunity of PTA strengthening driven by the mid - term increase in PXN [30]. - For ethylene glycol, domestic supply is high, imports are increasing, and inventories are expected to accumulate in Q4. Valuation is relatively low, and a short - selling strategy on rallies is recommended [32]. 3.

Group 1: Report Industry Investment Rating - No relevant content found Group 2: Core Viewpoints of the Report - For PTA, the near - term TA partial device maintenance led to a decline in the start - up rate, polyester load decreased, inventory continued to accumulate, and the basis remained weak while the spot processing fee improved slightly. PX start - up rate declined due to unexpected domestic maintenance, overseas devices ran stably, PXN strengthened month - on - month, disproportionation benefits remained weak and isomerization benefits weakened, and the US - Asia aromatics spread remained stable. In the future, TA will maintain a high maintenance state, downstream especially filament and staple fiber show no obvious pressure, combined with India's revocation of BIS certification, the inventory accumulation slope of TA is not high, and there are limited new productions in the far - month. The PX pattern is good, so pay attention to the opportunities of buying low for positive spreads and expanding processing fees [2]. - For MEG, the near - term domestic oil - based production increased the load, coal - based production had some maintenance and load reduction, the overall start - up rate declined, the restart of some overseas devices was postponed, the port inventory accumulated at the beginning of next week, the arrival forecast remained high during the week, the basis weakened, and the coal - based profit was low. In the short term, EG inventory accumulation is expected to continue, but considering that the profit is already at a low level after the coal price strengthened, the supply side may have some reduction in stages, and the space for further weakening of the current valuation is limited. In the long term, with new device launches and the suppression of warehouse receipts on the disk structure, the overall pattern is expected to weaken [2]. - For polyester staple fiber, the near - term device operation was stable, the start - up rate remained at 97.5%, the production and sales remained weak, and the inventory increased month - on - month. On the demand side, the start - up rate of polyester yarn remained stable, raw material inventory decreased while finished product inventory decreased, and the profit remained stable. Although the profit and start - up rate of polyester yarn did not improve significantly, the staple fiber's own exports maintained high growth, showing that there was no obvious inventory accumulation under high start - up. In the short term, new capacity launches are relatively limited, so pay attention to the opportunities of expanding processing fees at low prices and the situation of warehouse receipts [2]. - For natural rubber, the national explicit inventory remained stable at a relatively low absolute level, the price of Thai cup rubber remained stable, and rainfall affected rubber tapping. The strategy is to wait and see [6]. - For benzene - related products, the prices of relevant products such as ethylene, pure benzene, and styrene changed, and the domestic profits of PS, ABS, EPS, etc. also showed corresponding changes. The Asian spreads and production profits of these products need to be continuously monitored [9]. Group 3: Summaries According to Related Catalogs PTA - **Market data**: From November 10 - 14, 2025, the daily average basis of PTA spot transactions was 2601(-76). The PTA device of Sichuan Energy Investment with a capacity of 1 million tons was under maintenance.

PX start - up rate declined due to unexpected domestic maintenance, overseas devices ran stably, PXN strengthened month - on - month, disproportionation benefits remained weak and isomerization benefits weakened, and the US - Asia aromatics spread remained stable [2]. - **Outlook**: TA will maintain a high maintenance state, downstream especially filament and staple fiber show no obvious pressure, combined with India's revocation of BIS certification, the inventory accumulation slope of TA is not high, and there are limited new productions in the far - month. The PX pattern is good, so pay attention to the opportunities of buying low for positive spreads and expanding processing fees [2]. MEG - **Market data**: From November 10 - 14, 2025, the basis was around +54 for 01. The MEG devices of Hongsifang with a capacity of 300,000 tons and Huayi with a capacity of 200,000 tons were under maintenance.

1. Report Industry Investment Rating - The investment ratings for RU and NR are neutral, and the rating for BR is also neutral [10] 2. Core Viewpoints of the Report - The cost of natural rubber is strongly supported, but there is potential for inventory accumulation in the domestic market. It is recommended to focus on the reverse spread between RU01 and RU05. The supply pressure of RU may be less than that of NR in the later period, which is beneficial for the expansion of the price difference between RU and NR. The supply of BR is expected to remain stable in the short - term due to maintenance, and it mainly follows the price fluctuations of upstream butadiene. The inventory accumulation pattern may continue, but the loss of butadiene production profit may limit future output [10] 3. Summary by Related Catalogs Market News and Data - Futures: The closing price of the RU main contract was 15,390 yuan/ton, up 170 yuan/ton from the previous day; the NR main contract was 12,400 yuan/ton, up 220 yuan/ton; the BR main contract was 10,480 yuan/ton, up 50 yuan/ton [1] - Spot: The price of Yunnan - produced whole latex in the Shanghai market was 14,850 yuan/ton, up 100 yuan/ton; Qingdao Free Trade Zone Thai mixed rubber was 14,780 yuan/ton, up 80 yuan/ton; Thai 20 - standard rubber in Qingdao Free Trade Zone was 1,860 US dollars/ton, up 10 US dollars/ton; Indonesian 20 - standard rubber in Qingdao Free Trade Zone was 1,750 US dollars/ton, up 35 US dollars/ton; the ex - factory price of BR9000 from PetroChina Qilu Petrochemical was 10,300 yuan/ton, unchanged; the market price of BR9000 from Zhejiang Chuanhua was 10,420 yuan/ton, up 20 yuan/ton [1] Market Information - Heavy - truck market: In October 2025, the sales volume of the domestic heavy - truck market was about 93,000 units, a month - on - month decrease of about 12% and a year - on - year increase of about 40%.
