Report Industry Investment Ratings No relevant content provided. Core Views Polyolefins - The polyolefin market is under pressure, with a divergence in the fundamentals of PP and PE. PP shows a dual increase in supply and demand, but there is a slight inventory build - up this week under the pressure of new production capacity. PE has weak supply and demand, and although there is inventory reduction this week, port inventory remains high. The cost side is mixed, with high inventory and cost support in a continuous game [2]. Glass and Soda Ash - For soda ash, the overall supply - demand pattern is still bearish. Short - term observation is recommended, and opportunities to short on rebounds can be awaited later. For glass, short - term there is still some rigid demand support, but in the long - term, there are concerns about the sustainability of demand, and the price is expected to be under pressure [4]. PVC and Caustic Soda - The caustic soda market is expected to be weak in the short - term, and the overall trend is bearish.

The demand is weakening in some northern regions. The market sentiment has improved, and subsequent attention should be paid to the raw material output in the main production areas and macro - level changes [11]. Pure Benzene and Styrene - The supply - demand outlook for pure benzene is generally loose, and the price driver is weak. It is recommended to short on rebounds following the oil price. The supply - demand of styrene may remain in a tight balance, but the price driver is insufficient. EB12 can be shorted on rebounds [12]. Polyester Industry Chain - For PX, the short - term is expected to fluctuate in the range of 6200 - 6800. For PTA, the short - term is expected to fluctuate in the range of 4300 - 4800. For ethylene glycol, the price is under pressure. For short - fiber, the rebound space is limited. For bottle - chips, the supply - demand is in a loose pattern [13].

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, it's not advisable to be overly bearish on oil prices in the short - term. A range - trading strategy of buying low and selling high is maintained, but the current prices need to test OPEC's willingness to support prices through exports, so short - term waiting is recommended [3]. - For methanol, domestic production has increased, imports have risen, supply pressure has intensified, while demand has weakened. The high - inventory issue on the 01 contract will increasingly suppress spot prices. With no substantial short - term positive news from overseas supply, there may be further declines. However, the cost - effectiveness of short - selling after the sharp decline is low, and there is no clear driving force for long - positions, so waiting is advised [6]. - For urea, prices are consolidating at a low level with low volatility. The fundamentals lack a driving force. Supply has increased, demand is weak, and the supply - demand situation is relatively loose. Although the upside is limited, the downside is also restricted at these low prices, so waiting is recommended [9]. - For rubber, prices rebounded as expected. It's recommended to set a stop - loss and conduct short - term long - trades on pullbacks. A partial position for the hedging strategy of buying RU2601 and selling RU2609 is recommended [15]. - For PVC, the comprehensive profit of enterprises is at a low level this year, and valuation pressure is low in the short - term. However, supply is high, new devices are about to be commissioned, demand is weak, and exports are expected to decline, so there is a risk of continuous inventory accumulation. It's recommended to pay attention to short - selling opportunities in the medium - term [17]. - For pure benzene and styrene, the BZN spread is at a low level and has room for upward repair. The supply of pure benzene is relatively abundant, and the port inventory of styrene is decreasing significantly. Styrene prices may stop falling in the short - term [20]. - For polyethylene, OPEC+ plans to suspend production growth in Q1 2026, and the price of crude oil may have bottomed out. Although the downward space for PE valuation is limited, high - level warehouse receipts suppress the market. With the arrival of the seasonal peak season, demand may pick up, and prices are expected to fluctuate at a low level [23]. - For polypropylene, although the cost side indicates a potential increase in supply surplus, the downstream start - up rate has rebounded seasonally. With high inventory pressure and high - level warehouse receipts, the market may be supported when the supply - surplus situation on the cost side changes in Q1 next year [26]. - For PX, the current load is high, downstream PTA maintenance is frequent, and PTA processing fees are under pressure. It's expected to see a slight inventory increase in November, but it will be supported by aromatics blending and future supply - demand structure. It mainly follows crude oil fluctuations, and there may be opportunities for valuation increase in the medium - term [29]. - For PTA, supply is expected to increase due to new device commissioning and maintenance, and inventory is expected to accumulate in November. Although polyester demand may remain high, the upside is limited. Pay attention to the opportunity for PTA to strengthen driven by the increase in PXN in the medium - term [32]. - For ethylene glycol, domestic and overseas device loads are high, imports are increasing, and ports are starting to accumulate inventory. It's expected to see continuous inventory accumulation in Q4, and it's recommended to short - sell on rallies [34]. Summary by Related Catalogs Crude Oil - **Market Information**: The main INE crude oil futures closed up 4.90 yuan/barrel, or 1.07%, at 461.80 yuan/barrel.

The 1 - 5 spread was - 6, at - 107 [5]. - **Strategy Viewpoint**: Domestic production has increased, imports have risen, supply pressure has intensified, while demand has weakened. The high - inventory issue on the 01 contract will increasingly suppress spot prices. With no substantial short - term positive news from overseas supply, there may be further declines. However, the cost - effectiveness of short - selling after the sharp decline is low, and there is no clear driving force for long - positions, so waiting is advised [6]. Urea - **Market Information**: Spot prices in Shandong, Henan, and Hubei increased. The 01 contract on the futures market decreased by 7 yuan to 1660 yuan, with a basis of - 40. The 1 - 5 spread was - 5, at - 72 [8]. - **Strategy Viewpoint**: Prices are consolidating at a low level with low volatility. The fundamentals lack a driving force. Supply has increased, demand is weak, and the supply - demand situation is relatively loose. Although the upside is limited, the downside is also restricted at these low prices, so waiting is recommended [9]. Rubber - **Market Information**: The report previously suggested buying opportunities in rubber, and prices rebounded as expected. There are different views on the market. Bulls focus on factors such as limited production in Southeast Asia, seasonal trends, and improved demand expectations in China. Bears are concerned about uncertain macro - expectations, seasonal low demand, and potential under - performance of supply benefits. As of November 6, 2025, the operating rate of all - steel tires in Shandong increased, while that of semi - steel tires decreased. As of November 2, 2025, China's natural rubber social inventory increased. Spot prices of some rubber products increased [12][14]. - **Strategy Viewpoint**: Prices rebounded as expected.

Report Industry Investment Ratings - No industry investment ratings were provided in the reports. Core Views Natural Rubber - The natural rubber market is expected to enter a seasonal inventory accumulation cycle, with short - term price range - bound. If raw material supply is smooth, there is further downward potential; if not, prices are expected to range between 15,000 - 15,500 [1]. Glass and Soda Ash - For soda ash, the long - term supply - demand pattern is bearish, and short - term rebounds should be treated as opportunities to go short. For glass, short - term long opportunities can be seized on dips, but the industry still needs capacity clearance to solve the over - supply problem [3]. Methanol - The methanol market is trading on the "weak reality" logic, with the core contradiction being high port inventories. Before Iranian gas restrictions, the weak reality will continue to be priced in [6]. Polyester Industry Chain - PX supply is stable, but November's supply - demand is expected to be loose. PTA is expected to be in a tight - balance in the short - term but loose in the medium - term. Ethylene glycol is under pressure due to expected high inventory accumulation. Short - fiber and bottle - chip markets also face supply - demand challenges [8]. Polyolefins - Polypropylene and polyethylene both show increasing supply and demand, but the market still faces pressure from new capacity and supply increases [11]. PVC and Caustic Soda - Caustic soda prices are expected to be weak in the short - term due to increased supply and weak demand. PVC is in an over - supply situation, and prices are expected to continue to be weak [13]. Pure Benzene and Styrene - Pure benzene supply is expected to be loose, and price drivers are weak. Styrene supply - demand may be in a tight - balance, but cost support is insufficient [14].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - For plastics, the supply is under pressure, the market may continue to seek a bottom weakly. With the restart of devices and the increase in domestic and foreign supplies, while the demand side has insufficient restocking power and high inventory, the fundamentals have no upward driving force, so the previous short positions should be held, and short - selling on the short - term single side is not recommended [4]. - For PP, the weak fundamentals remain unchanged, and it will run weakly following the cost side. With high inventory, increasing supply, and weakening demand, there is a high de - stocking pressure in the future [9]. 3. Summary According to Relevant Catalogs 3.1 Plastic and PP Market Review - **Plastic**: This week, plastics opened high and closed low, with two consecutive negative weekly lines. It opened 16 points higher at 6915 on Monday, reached a weekly high of 6939, then fell unilaterally to a weekly low of 6745 on Thursday morning, and finally closed at 6802, down 97 points or 1.4% from last week's closing. The weekly amplitude was 194 points [3][13]. - **PP**: This week, PP also opened high and closed low, with two consecutive negative weekly lines. It opened 10 points higher at 6600 on Monday, reached a weekly high of 6629, then fell unilaterally to a weekly low of 6415 on Thursday morning, and finally closed at 6464, down 126 points or 1.9% from last week's closing. The weekly amplitude was 214 points [8][16]. 3.2 Valuation - For plastics, the basis and monthly spread are running weakly, and the single is at a year - on - year high. The oil - based valuation is at a medium level, and LLDPE is at a medium position in the same period [19][26][28]. - For PP, the valuation is moderately high [34]. 3.3 Production Capacity and Supply - **Production Capacity**: In 2025, the planned PE production capacity is 613 tons (year - on - year + 17%), with 463 tons already put into production from January to October and 120 tons remaining. The planned PP production capacity is 511 tons (year - on - year + 11%), with 456 tons already put into production from January to October and 45 tons remaining. In 2026, it is still in a high - production - capacity cycle, and the probability of PP device delay is relatively high, so the opportunity to shrink LP05 can be concerned [35]. - **Supply**: In November, the start - up rate shows an upward trend.

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views of the Reports Natural Rubber Industry - The natural rubber market may enter a seasonal inventory accumulation cycle, with short - term price fluctuations in a range. If raw material supply is smooth, there is further downward potential; if not, the price is expected to range between 15,000 - 15,500 [1]. Glass and Soda Ash Industry - For soda ash, the supply - demand pattern is bearish in the medium - long term, and short - term rebounds can be used as opportunities to go short. For glass, there are short - term trading opportunities for low - level rebounds, but the industry still needs capacity clearance [3]. Methanol Industry - The market is trading on the "weak reality" logic, with the core contradiction being high port inventories. The inventory problem of the 01 contract cannot be resolved, and the weak reality will continue to be priced in before Iranian gas restrictions [6]. Polyester Industry Chain - PX may fluctuate between 6,200 - 6,800; PTA may range between 4,300 - 4,800; for ethylene glycol, hold short - call options and conduct reverse spreads; short - fiber has limited rebound space; bottle - grade polyester chips will follow cost fluctuations [8]. Polyolefin Industry - Polypropylene shows a pattern of increasing supply and demand with inventory reduction, but the basis is weak. For polyethylene, the demand for agricultural films is strong, but attention should be paid to the potential impact of year - end foreign market inventory clearance [11]. PVC and Caustic Soda Industry - Caustic soda prices are expected to be weak in the short term, and the market trend is bearish. PVC is in an oversupply situation, and prices are expected to continue to be weak at the bottom [13]. Pure Benzene - Styrene Industry - Pure benzene supply is expected to be loose, and prices should be shorted on rallies following oil prices. Styrene supply - demand may be in a tight balance, but price drivers are insufficient, and the EB12 contract should be shorted on price rebounds [14]. 3.

Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core Views of the Report - For crude oil, although the geopolitical premium has disappeared and OPEC's production increase is minimal, supply has not yet increased significantly, so short - term bearish sentiment on oil prices should be cautious. Maintain a range - trading strategy of buying low and selling high, but currently wait and see to test OPEC's export price - support intention [2] - For methanol, with rising domestic production and high imports, supply pressure increases. Demand is weak, leading to high enterprise and port inventories. The weak reality remains unchanged, and the high - inventory problem of the 01 contract may further suppress the spot price. It is recommended to wait and see [3] - For urea, prices are consolidating at a low level with low volatility. The fundamentals lack drivers, and supply and demand are relatively loose. There is limited upward momentum, but the downside space is also limited at current low prices. It is advisable to wait and see [5] - For rubber, prices are rebounding as expected. Set stop - losses and conduct short - term long trades on pullbacks. Partially build positions for the hedge of buying RU2601 and selling RU2609 [11] - For PVC, the supply is strong and demand is weak, with poor export prospects. There is continuous inventory accumulation pressure. It is recommended to consider short - selling on rallies in the medium term [13] - For pure benzene and styrene, pure benzene prices are falling, while styrene futures prices are rising. The BZN spread has room for upward repair. Styrene prices may stop falling in the short term due to high - level inventory reduction [16] - For polyethylene, the PE valuation has limited downward space, but high - level warehouse receipts suppress the market. With the arrival of the seasonal peak season, prices may remain range - bound at a low level [19] - For polypropylene, in a context of weak supply and demand with high inventory pressure, there is no prominent short - term contradiction. The price may be supported when the supply - surplus situation of the cost side changes in the first quarter of next year [22] - For PX, it is expected to have a slight inventory increase in November, with prices mainly following crude oil fluctuations. There may be opportunities for valuation increases in the medium term [25] - For PTA, continuous inventory accumulation is expected in November, and processing fees are under pressure. There may be opportunities for PTA to strengthen driven by the increase in PXN in the medium term [28] - For ethylene glycol, there is expected to be continuous inventory accumulation in the fourth quarter. It is recommended to short on rallies [30] Group 3: Summary by Related Catalogs Crude Oil - **Market Information**: INE's main crude oil futures closed up 0.10 yuan/barrel, a 0.02% increase, at 460.60 yuan/barrel.

PP2601 closed at 6471 yuan/ton, down 37 yuan/ton (-0.57%), with an open interest of 652,800 lots and an increase of 818,000 lots [6] - Futures remained weak, which was negative for market sentiment. Most trade offers fell, and downstream purchasing enthusiasm was low, with only rigid demand purchases [6] - There are no new investment plans in November. Some maintenance devices will be restarted one after another, and the device operating load may continue to increase, and the pressure of new capacity expansion will intensify the imbalance between supply and demand [6] - The seasonal peak of agricultural film production has passed, and the demand for pipes has increased first and then decreased. The production of PP woven bags has been boosted by packaging demand, and BOPP enterprises are mainly digesting inventory. The downstream is dominated by fear of falling prices, and the willingness to stock up is low, which further drags down the transaction price [6] - In general, under the dual effects of weak cost support and continuous loose supply and demand, the downward pressure on polyolefin prices is expected to continue [6] Group 4: Industry News - On November 6, 2025, the inventory level of major producers was 695,000 tons, a decrease of 15,000 tons (-2.11%) from the previous working day; the inventory at the same time last year was 720,000 tons [7] - The PE market price continued to be weak.

The decline of propylene price widened, and the downstream factories were more wait - and - see, and the overall market transaction was still average [7] - The PP market remained weak, and the prices of some grades dropped by 30 - 50 yuan/ton. The mainstream price of North China drawstring was 6,220 - 6,450 yuan/ton, in East China was 6,330 - 6,550 yuan/ton, and in South China was 6,390 - 6,550 yuan/ton [7]

Report Industry Investment Ratings No relevant content provided. Core Views Methanol Market - The current methanol market is trading on the "weak reality" logic, with the core contradiction centered on high port inventories. The 01 contract faces challenges in inventory digestion, and the weak reality pattern may continue until Iranian gas restrictions are implemented. The 05 contract is expected to see significant inventory reduction, so attention can be focused on the MTO profit shrinkage opportunity of the 05 contract [1][3]. Polyester Industry Chain - PX supply is generally stable with some plant overhauls offset by xylene supplements. Demand has some support in the short - term, but the November supply - demand is expected to be loose, and price drivers are limited. PTA may have a slight inventory build - up, and its price rebound space is restricted. Ethylene glycol is expected to have a high inventory build - up in November - December, facing upward pressure. Short - fiber supply remains high in the short - term, but demand may weaken seasonally, and its price rebound space is limited. Bottle - chip supply and demand are in a loose pattern, and it follows cost fluctuations [6]. Polyolefin Market - PP supply increase is slowing due to more unplanned overhauls, while PE supply is expected to increase as overhauls peak. Demand has improved, but overall, there is pressure from increasing supply and decreasing demand. The 01 contract has inventory pressure, while the 05 contract may offer long - term low - buying opportunities, and the month - spread is biased towards reverse arbitrage [8]. PVC and Caustic Soda Market - Caustic soda supply is expected to increase in November, with weak demand support, and its price is expected to be weakly stable. PVC supply - demand is in an oversupply situation, and its price is expected to continue to fluctuate weakly at the bottom [11]. Pure Benzene and Styrene Market - Pure benzene supply is expected to be loose in November, with limited demand support and increasing port inventories. Its price driver is weak. Styrene supply may slightly decrease in November, demand is expected to change little, and its price driver is also limited [12].
