Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The overall market shows a complex and volatile situation, with different sectors having different trends and influencing factors. For example, the A - share market is affected by macro - data and shows an upward - then - downward trend; the steel and ore market is expected to be weak in the medium - to - long - term; and the energy market is influenced by geopolitical conflicts and supply - demand relationships [10][12][35]. Summary by Related Catalogs Macro Information - The 22nd issue of Qiushi magazine published President Xi Jinping's important article. The National Bureau of Statistics released October economic data, showing a slowdown in multiple indicators. The prices of commercial housing in 70 cities declined. The Chinese government reminded citizens to avoid traveling to Japan. The State Council studied "two - important" construction and consumption - promotion policies. The central bank will conduct a large - scale reverse - repurchase operation. The US will release multiple economic data. The Guangzhou Futures Exchange will list platinum and palladium futures. The market supervision department issued an anti - monopoly compliance guide. The national child - rearing subsidy system has been implemented, and the lithium - battery industry chain has seen a price increase. Trump adjusted the scope of "reciprocal tariffs" [4][5][6][7][8]. Macro Finance - **Stock Index Futures**: Adopt a volatile mindset and temporarily hold off on trading. The A - share market rose and then fell, affected by macro - data. The decline in industrial growth, consumption, and investment may be due to technical factors, export slowdown, anti - involution, and the real - estate downturn [10]. - **Treasury Bond Futures**: The market's expectation of monetary easing has declined, but interest - rate cuts cannot be ruled out. Maintain the view of increased easing in Q4. The money market is affected by the approaching tax period, and the stock - bond seesaw effect is weakly effective [11]. Black - **Steel and Ore**: In the short - term, expect a volatile consolidation; in the medium - to - long - term, maintain a bearish view when prices are high. The supply - demand relationship is weak, with high inventory and low profit for steel mills. The price is affected by low - price transactions and may remain weak [12][13]. - **Coking Coal and Coke**: The prices may continue to decline in the short - term. In the medium - term, the mine's production is restricted by policies, and the demand for steel is weak in the off - season, but the strong thermal - coal price provides some support [14]. - **Ferroalloys**: In the long - term, the oversupply situation is difficult to alleviate, so maintain a bearish view when prices are high. In the short - term, it is recommended to wait and see. The prices are fluctuating narrowly, and the cost of manganese - silicon is relatively stable [15]. - **Soda Ash and Glass**: Currently, it is recommended to wait and see. The soda - ash industry has production fluctuations and cost increases, while the glass industry's strong sales have not continued, and the market is concerned about demand and inventory [16]. Non - ferrous Metals and New Materials - **Lithium Carbonate**: The short - term fundamentals are good, but the demand may weaken in Q1 next year, limiting price increases. After the demand weakens, the price may correct, and it is advisable to buy on dips [18]. - **Industrial Silicon and Polysilicon**: Industrial silicon has no prominent supply - demand contradictions and can be bought on dips or sell out - of - the - money put options. Polysilicon is expected to continue to fluctuate, influenced by policy expectations and supply - demand relationships [19]. Agricultural Products - **Cotton**: The supply pressure is large, and the demand is weak. The price is undervalued compared to the spot, which limits the decline. It is expected to oscillate at a low level [23][24]. - **Sugar**: The domestic sugar supply - demand situation is expected to be bearish. Before the large - scale arrival of new sugar, it is advisable to wait and see. In the long - term, there is still supply pressure [25][27]. - **Eggs**: The spot price is weak, and the futures price may oscillate. The in - production laying - hen inventory is high, but it is expected to decline. It is recommended to short the near - term contracts [28]. - **Apples**: The price is expected to be strong in a volatile manner. The inventory is low, and the price is high. The future consumption trend will be the focus [30]. - **Corn**: The spot price has rebounded, but the supply pressure is still accumulating. It is necessary to pay attention to the new - grain sales progress and the release of policy wheat [31]. - **Red Dates**: Temporarily wait and see. The weak spot market in the sales area has a negative impact on the new - date ordering price [32]. - **Pigs**: The supply pressure continues, and the demand is average. The spot price is likely to oscillate weakly. It is recommended to short the near - term contracts [33]. Energy and Chemicals - **Crude Oil**: In the short - term, it is expected to be strongly volatile, but the long - term downward trend of oversupply remains unchanged. The price is affected by geopolitical conflicts and supply - demand forecasts [35]. - **Fuel Oil**: The price will follow the oil price, with a supply - abundant and demand - weak structure. The short - term focus is on supply concerns after the sanctions on Russia [36]. - **Plastic**: The supply pressure is large, and it is expected to be weakly volatile. The current price provides some support for producers [36][37]. - **Rubber**: Pay attention to the strategy of expanding the ru - nr spread. The price may oscillate in the short - term, with supply in the peak season and support at the bottom [37]. - **Methanol**: The near - term contracts are expected to be weakly volatile, and the far - term contracts can be moderately long after the rebound drive appears. The supply pressure is large, and the inventory is high [38][39]. - **Caustic Soda**: Wait for long - position opportunities after a significant decline. Pay attention to the cost support. The spot price is falling, and the futures price is weak [40]. - **Asphalt**: The price fluctuation is expected to increase, and the focus is on the price bottom after the winter - storage game [41]. - **Polyester Industry Chain**: It is expected to continue to be strong in the short - term, driven by improved supply - demand and market sentiment [42]. - **Liquefied Petroleum Gas**: Although there are short - term positive factors, it is not advisable to chase the rise. Consider shorting at high prices in the medium - to - long - term [43]. - **Paper Pulp**: The fundamentals are relatively stable, and it is expected to maintain a wide - range oscillation. Observe the digestion of old warehouse receipts and spot transactions [45]. - **Logs**: The fundamentals are weakly oscillating, and the price is under pressure. The inventory is expected to increase, and the market is in the off - season [46]. - **Urea**: Wait and see, subject to specific policies. The spot price is falling, and the futures price is oscillating [47]. - **Synthetic Rubber**: The short - term price will oscillate within a range. Be cautious when going long and consider selling call options after the rebound [48].

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Crude Oil - Despite concerns about crude oil supply glut, US government's end of shutdown and tightened sanctions on Russia led to a slight rebound in overnight oil prices. OPEC+ faces continuous production - increase pressure, with a weak fourth - quarter supply - demand outlook. EIA周报 shows significant increase in US crude production and large inventory growth, so oil prices remain under pressure. Short - term Brent may trade in the range of $60 - 66 per barrel, with a bearish view. Attention should be paid to substantial sanctions on Russia and the Russia - Ukraine geopolitical situation [2]. Polyolefins - PP shows both supply and demand increase. Supply rises due to fewer maintenance, and demand remains resilient in the automotive and home - appliance sectors, but there is slight inventory accumulation this week under new - capacity pressure. PE has weak supply and demand. Although unplanned maintenance eases supply pressure, import sources are abundant, and non - agricultural - film demand generally declines. There is inventory reduction this week, but port inventory remains high. The cost side has crude oil fluctuating and coal strengthening, with a slight repair in PDH profit. High inventory and cost support continue to compete, and market expectations are still weak [4]. Methanol - Delayed gas restrictions in Iran put significant pressure on the port methanol market. High inventory, combined with positive import profit from Iran, leads to continuous trading and weakening willingness to hold goods, resulting in price decline and stable basis. In the inland market, Baofeng continues external procurement, and Jiutai has unexpected maintenance, with subsequent increase in domestic production. Overseas gas restrictions are less than expected. On the demand side, multiple MTO units reduce load due to profit reasons, and traditional downstream purchases for rigid demand. The market currently trades on the "weak reality" logic, with the core contradiction being high port inventory. The inventory problem of the 01 contract cannot be solved, and the weak reality will continue to be traded before gas restrictions in Iran [8]. Natural Rubber - On the supply side, there are still periodic rainfall disturbances in overseas production areas, but overall, a strong output is expected during the peak - production period, and raw - material prices have some downward space. Domestic production areas are gradually entering the output - reduction period, with firm domestic raw - material prices. On the demand side, some northern regions are entering the off - season in the month, with slower market sales, mainly digesting inventory and purchasing as needed. With market digestion, some replenish in small quantities in the middle of the month. In the short term, due to large macro fluctuations, rubber prices are expected to fluctuate. Follow the raw - material output in the peak - production period of major production areas and macro changes. If raw - material supply is smooth, prices may weaken; if not, rubber prices are expected to trade around 15,000 - 15,500 [11]. PVC and Caustic Soda - **Caustic Soda**: Low - concentration caustic soda gets price support from increased inquiries from alumina plants, but overall, there is a lack of real positive factors. The caustic - soda industry still faces supply - demand pressure, with few maintenance enterprises and an increasing supply. The main downstream alumina price is weakening, with shrinking industry profit and increasing losses, so the main demand side provides weak support, suppressing caustic - soda prices. Although there may be periodic replenishment demand from middle - and downstream inventory consumption, prices are still under pressure due to increasing supply and weakening demand. The non - aluminum market is sluggish. It is expected that caustic - soda prices will trend down in the long run, but there is short - term support from downstream periodic demand. Track the rhythm and sustainability of downstream replenishment [12]. - **PVC**: The supply - demand surplus problem has not improved, with increasing supply pressure, weakening demand expectations, insufficient cost support, and no positive macro expectations. It is expected that prices will continue to weaken. On the demand side, major downstream sectors such as real estate are still weak, and product enterprises like profiles and pipes have limited new orders, mainly purchasing for rigid demand, which cannot provide continuous market support. In November - December, there will still be an impact from new production capacity. After the maintenance of Inner Mongolia Sanlian, Qilu Petrochemical, and Inner Mongolia Junzheng ends next week, production is expected to increase. From November to January of the next year is the traditional off - season, with reduced outdoor construction in the north, and overall real - estate demand decline is a negative factor. The situation of anti - dumping duties in India is unclear, and exports are mainly in a wait - and - see state. The supply - demand surplus persists, and prices are not optimistic, expected to continue weakening at the bottom [12]. Glass and Soda Ash - **Soda Ash**: Recently, with the previous price decline, middle - and downstream buyers have increased purchases, leading to a rebound in the futures price. However, the overall surplus situation is still prominent. Fundamentally, weekly production remains at a high level of around 750,000 tons, with obvious surplus compared to current rigid demand. Manufacturer inventory has been transferred to the middle - and downstream, and trade inventory continues to rise. In the medium term, there is no expectation of significant downstream capacity increase, so the overall demand for soda ash will continue the previous rigid - demand pattern. Without actual capacity exit or load reduction, the supply - demand situation will face further pressure. Track macro fluctuations and soda - ash plant load - adjustment situations. The supply - demand outlook is bearish. Short - term operation should be on the sidelines, and wait for opportunities to short on rebounds [13]. - **Glass**: Sales have weakened significantly, and the sales - to - production ratio has fallen below 100% in recent days. Although four production lines in the Shahe area were cold - repaired last week, there will be production - line restart and ignition, adding about 3,650 tons of daily capacity, which will put pressure on the supply side. The latest deep - processing order days have slightly improved, and there is still some rigid demand support in November as it is the year - end rush season. However, in the long - term, at the end of the peak season, there are concerns about future demand sustainability. As the temperature drops in the north, outdoor construction will stop, and glass prices will face pressure after December. The real - estate industry is still in the bottom cycle, with significant reduction in construction volume. The industry needs capacity exit to solve the surplus problem. The high sales - to - production ratio of spot has ended, and glass is expected to be weak in the short term [13]. Polyester Industry Chain - **PX**: Currently, Asian and domestic PX loads remain high. In the short - term, PTA load is maintained, and the previous terminal and polyester demand was better than expected. With low polyester inventory, load is expected to remain relatively high from November to December. PX demand still has short - term support. Yesterday, PX showed a strong trend due to the lifting of India's BIS certification and the start of the Asia - America aromatics arbitrage. However, limited by weak overall oil - price support and expected weakening of terminal demand in the industry chain, the PX rebound space is restricted. Short - term PX short positions should be avoided [14]. - **PTA**: There are still many PTA plant maintenance plans in November. The previous terminal and polyester demand was better than expected. With low polyester inventory, load is expected to remain relatively high in November - December. The supply - demand balance in November is expected to be tight, but it will be loose from December to the first quarter of next year. Yesterday, PTA showed a strong trend due to the cancellation of India's BIS certification and PX transfer - demand news, but the spot - market negotiation atmosphere was dull, and the basis was still weak. The PTA rebound space is restricted. Short - term TA should pay attention to the $4800 pressure level, and short positions should be avoided. TA1 - 5 can be treated as a rolling reverse spread [14]. - **Ethylene Glycol (EG)**: Recently, some coal - based EG plants are under maintenance, but Jinghai Petrochemical's plant has restarted production. Previously - maintained coal - based plants plan to restart in the middle - and late - November. Domestic supply remains high, and North American EG load has reached a high level. Middle - East supply shows no reduction, and overseas shipments are concentrated in January. Currently, polyester load is declining, and due to the high expected inventory accumulation in November - December, EG is under pressure. Hold out - of - the - money call options on EG2601 with a strike price of no less than 4100; go for reverse spreads on EG1 - 5 at high prices [14]. - **Short - fiber**: Currently, short - fiber factories have low inventory levels and reasonable processing fees, so short - fiber supply remains relatively high. In November, there is an expected seasonal weakening of terminal demand. Yesterday, the cancellation of India's BIS certification made raw - material PTA stronger, but it mainly benefited PTA and long - fiber, having relatively little impact on short - fiber. In the short - term, due to the weak supply - demand expectation, the short - fiber rebound space is restricted, and processing fees are expected to be compressed. The strategy is the same as PTA for single - side trading; the processing fee on the disk fluctuates in the range of 800 - 1100, and short positions should be taken at high prices [14]. - **Bottle - grade polyester chips**: In mid - November, the Huarun plant has both maintenance and restart. According to Longzhong Information, the commissioning of Dongying Fuhai's new plant is postponed, and domestic supply changes little. Considering the November market off - season, soft - drink and catering demand decline slightly, and demand provides insufficient support for bottle - grade chips. The supply - demand situation remains loose. Bottle - grade chips' social inventory is likely to enter the seasonal inventory - accumulation phase, with prices fluctuating with the cost side. Processing fees are limitedly boosted by supply - demand and change with raw - material costs. The strategy for single - side trading is the same as PTA; the main - contract processing fee on the disk is expected to fluctuate in the range of 300 - 450 yuan per ton [14]. Pure Benzene and Styrene - **Pure Benzene**: There are new capacity commissioning, plant restart, and planned/unplanned maintenance expectations for pure benzene recently, but overall domestic supply may remain loose. On the demand side, some loss - making downstream products have production - reduction and price - protection expectations, so demand support is limited. Although East - China port inventory decreased this week, supply pressure remains. There is an expected amount of imports from November to December, but the US - Asia arbitrage window and gasoline - blending may disrupt market sentiment, and the actual impact needs further consideration. With weak crude - oil supply - demand expectations, cost support is limited, and the rebound space is restricted. Follow plant changes. In the short - term, BZ2603 has weak self - driving force, pay attention to the 5640 pressure level, and be cautious about chasing up [16]. - **Styrene**: Two new styrene plants are operating stably, and previously - shut - down plants have restarted. There are also expected planned/unplanned maintenance in the near future, so overall supply may remain stable. Downstream EPS enters the seasonal off - season and reduces its operating rate due to high product inventory. PS has new plant commissioning and restart, and ABS remains stable. Overall demand changes little. Although inventory decreased this week, it is still at a high level, restricting the upside. Overseas and plant accidents may disrupt the domestic market. Overall, styrene supply - demand is expected to be in a tight balance, with insufficient price - driving force. Follow plant restart and production - reduction situations and cost changes. In the short - term, EB12 price may fluctuate with the cost side [16]. 3.

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views Polyester Industry - PX: In the short - term, it may fluctuate between 6200 - 6800. Suggest to reduce long positions on rallies and short above 6800 [1]. - PTA: It is expected to have a limited rebound, with short - term trading range between 4300 - 4800. Adopt a rolling reverse spread strategy for TA1 - 5 [1]. - Ethylene Glycol: Hold out - of - the - money call options with a strike price of no less than 4100 for EG2601 and conduct a high - level reverse spread for EG1 - 5 [1]. - Short Fiber: The rebound space is limited, and the processing fee may be compressed. The strategy is the same as PTA, and the processing fee on the disk may fluctuate between 800 - 1100 [1]. - Bottle Chip: PR follows the cost - end fluctuations, and the processing fee on the main contract disk is expected to fluctuate between 300 - 450 yuan/ton [1]. Methanol Industry The market is trading the "weak reality" logic, with the core contradiction being high port inventory. Before the gas restriction in Iran, the 01 contract's inventory problem cannot be solved [2]. Polyolefin Industry PP and PE have differentiated fundamentals. PP shows both supply and demand growth but accumulates inventory slightly this week. PE has weak supply and demand, with high port inventory. The market outlook remains weak [5]. Glass and Soda Ash Industry - Soda Ash: The overall supply - demand pattern is bearish. In the short - term, it is advisable to wait and see, and look for opportunities to short on rebounds later [7]. - Glass: It is expected to be weak in the short - term. In the long - term, the industry needs capacity clearance to solve the over - supply problem [7]. PVC and Caustic Soda Industry - Caustic Soda: The price is expected to trend downwards in the long - term but may have short - term support from downstream demand. Monitor the downstream restocking rhythm [8]. - PVC: The supply - demand remains in an over - supply pattern, and the price is expected to continue the weak trend at the bottom [8]. Natural Rubber Industry In the short - term, the rubber price is expected to fluctuate. If the raw material output in the main production areas is smooth, there is further downside potential [9]. Crude Oil Industry The short - term oil price is expected to fluctuate within a range, with Brent crude oil likely to trade between 60 - 66 dollars per barrel [10]. Pure Benzene and Styrene Industry - Pure Benzene: The supply - demand is expected to be loose, and the price driver is weak. Short - term BZ2603 should be treated as short on rallies following the oil price [14]. - Styrene: The supply - demand may turn loose, and the price driver is insufficient. EB12 should be shorted on price rebounds [14]. 3.

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.

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Views - The polyester industry chain is weak due to the continuation of the China - US game. The supply - demand imbalance is prominent, and the market is affected by factors such as crude oil price fluctuations, production capacity changes, and demand trends [2][3][5]. - For the strategy, it is recommended to cautiously short - sell PX/PTA/PF/PR on rallies for hedging, long PF processing fees at low levels, and conduct reverse spreads on PX/PTA2601 - 2605 [5][6]. 3. Summary by Directory Market News and Data - The Chinese Ministry of Commerce announced counter - measures against 5 US - related subsidiaries of Hanwha Ocean Co., Ltd. on October 14, 2025, in response to the US 301 investigation on China's maritime, logistics, and shipbuilding industries [1]. Market Analysis - **Cost Side**: During the China - US trade war, the leaders of both sides will meet around the end of the month. After the National Day, China's import demand slowed down while US exports increased, and Middle - East exports also rose, leading to an oversupply situation. Crude oil prices dropped sharply due to the renewed tariff war threat from the US, but there were some signs of easing later [2]. - **PX**: China's PX load has recovered to a relatively high level. With the restart of overseas units, the overall PX operation rate has increased. The postponement of PX maintenance plans in the fourth quarter and capacity expansion of some units have weakened the PX supply - demand outlook in the fourth quarter [2][5]. - **TA**: The PTA spot processing fee has been repaired but is still suppressed. The inventory accumulation rate has narrowed in October - November due to more maintenance plans and postponed new - unit launches, but there is significant inventory accumulation pressure in December [3][5]. - **Demand**: The polyester operating rate is 91.5% (unchanged from the previous period). The demand for filament yarn improved before the National Day, but the increase in polyester load is limited, and the sustainability of demand improvement needs attention [3]. - **PF**: The spot production profit is 300 yuan/ton (up 36 yuan/ton from the previous period). The inventory of direct - spun polyester staple fiber has decreased to a low level, and the short - term supply - demand situation is better than that of raw materials [4]. - **PR**: The spot processing fee of polyester bottle - grade chips is 509 yuan/ton (up 1 yuan/ton from the previous period). The inventory of domestic polyester bottle - grade chip factories has increased, and the supply - demand pressure is large under the pressure of new - unit launches [4]. Strategy - **Unilateral**: Cautiously short - sell PX/PTA/PF/PR on rallies for hedging [5]. - **Cross - Variety**: Long PF processing fees at low levels: PF2511 - 0.855PTA2601 - 0.332MEG2601 [6]. - **Cross - Period**: Conduct reverse spreads on PX/PTA2601 - 2605 [6]. Graphical Data - **Price and Basis**: Includes TA and PX contract price trends, basis, and cross - period spreads [10][11]. - **Upstream Profits and Spreads**: Covers PX processing fees, PTA spot processing fees, and South Korean xylene isomerization and disproportionation profits [17][20]. - **International Spreads and Import - Export Profits**: Involves toluene spreads between the US and Asia, toluene - naphtha spreads, and PTA export profits [25][27]. - **Upstream PX and PTA Operation**: Shows the operating rates of PX and PTA in China, South Korea, and Taiwan [28][31][33]. - **Social Inventory and Warehouse Receipts**: Presents the social inventory and warehouse receipts of PTA and PX [36][39][40]. - **Downstream Polyester Load**: Covers the production and sales of filament and staple fiber, polyester load, and the inventory days of filament factories [48][50][59]. - **PF Detailed Data**: Includes the load, inventory, and profit - related data of polyester staple fiber [68][74][80]. - **PR Fundamental Detailed Data**: Involves the load, inventory, and processing fees of polyester bottle - grade chips [90][96][98].

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the given reports. 2. Core Views of Each Report Methanol Industry - The methanol market has a relatively healthy inventory pattern due to high supply in the inland and continuous external procurement by some olefin plants, which supports prices. However, demand is weak due to the traditional off - season, and the overall valuation is neutral. The market is currently swaying between high inventory and weak basis in reality and the expectation of overseas gas restrictions in the future. Attention should be paid to the inventory inflection point [2]. Crude Oil Industry - Last week, oil prices oscillated, with the main trading logic being the continuous game between the supply - tightening expectation caused by geopolitical risks and concerns about weak macro - demand and supply surplus. In the short term, the market may continue to maintain a range - bound pattern in the tug - of - war between geopolitical risks and weak fundamentals. It is recommended to mainly adopt a wait - and - see approach for single - side trading, and a strategy of expanding spreads for option trading [7]. Chlor - Alkali Industry - For caustic soda, the spot price may stabilize, and the decline space of the futures price may be limited. Attention should be paid to the purchasing rhythm of alumina plants and device fluctuations. For PVC, the overall supply - demand pattern shows a marginal improvement trend, and it is expected to stop falling and stabilize in September. Attention should be paid to downstream demand performance [12]. Urea Industry - The urea futures price is running weakly, mainly due to the phase mismatch between the continuous increase in supply and weak domestic demand. Although export orders support some enterprises, the export's ability to digest inventory is limited. The market sentiment is restricted by high inventory and weak demand [18]. Polyolefin Industry - The market shows a pattern of "decreasing supply and increasing demand", and the core contradiction is not obvious. For PP, the PDH and external propylene procurement profits are suppressed, and the basis is still weak. For PE, the current maintenance is relatively high, and the short - term supply pressure is small, but attention should be paid to the supply rhythm. Attention should also be paid to downstream restocking before the Double - Festival [21]. Pure Benzene and Styrene Industry - The weekly supply - demand of pure benzene is weak, and the price driving force is weak. In the short term, BZ2603 follows the fluctuations of oil prices and styrene. The weekly supply - demand of styrene has improved, and there is an expectation of further improvement in the future. The low price of styrene has support, but the rebound space is limited due to high port inventory [43]. Polyester Industry - For PX, the supply is increasing to a relatively high level, and the short - term demand has some support, but the mid - term supply - demand is expected to be tight, and the price has support at the low level. However, the cost support is limited, and the rebound space is restricted. For PTA, the supply - demand is expected to be tight in September, but the basis and processing fee repair driving force are limited. For ethylene glycol, the supply - demand pattern is strong in the near term and weak in the long term. For short - fiber, the short - term supply - demand is weak, and it mainly follows the raw material fluctuations. For bottle - chips, the supply increases slightly, and the demand may decline, and the processing fee space is limited [47]. 3.
