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, 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 it's recommended to wait and see for now, waiting for a decline in OPEC exports to confirm the market [3]. - For methanol, the slow import unloading process has slowed port inventory accumulation. The market's main contradiction lies in the unexpected slow unloading due to previous sanctions and recent weather. Although there are potential bullish factors, the overall market structure is weaker than in previous years. It's recommended to wait and see [4]. - For urea, the supply - side device maintenance is over, and the demand - side compound fertilizer production has increased. The enterprise inventory accumulation has slowed down. The spot price has limited downward space, and there are still some positive factors to be released. It's recommended to wait and see or consider long - position opportunities at low prices [7]. - For rubber, the rubber price is strong. Short - term trading with quick entry and exit is recommended, and partial position - building for the hedging strategy of buying RU2601 and selling RU2609 is suggested [13]. - For PVC, the enterprise's comprehensive profit has declined to a low level, but the supply is strong, and the demand is weak. The export expectation is poor, and there is a continuous inventory accumulation pressure. It's recommended to consider short - position opportunities in the medium - term [16]. - For pure benzene and styrene, the BZN spread has room for upward repair. The port inventory of styrene is at a high level, and the price may stop falling periodically [20]. - For polyethylene, the cost - side supports the rebound of crude oil prices. The inventory is being reduced at a high level, and the price may maintain a low - level shock [23]. - For polypropylene, the cost - side supply is in an oversupply pattern, and the overall inventory pressure is high. There is no prominent short - term contradiction [26]. - For PX, the current load is high, and the downstream PTA has many maintenance operations. The inventory is difficult to continuously reduce, and it mainly follows the fluctuation of crude oil [29]. - For PTA, the short - term supply - side maintenance has decreased, and there is a slight inventory accumulation. The demand - side polyester load is expected to remain high, but there is limited room for improvement. The PXN is under pressure [30]. - For ethylene glycol, the domestic supply is high, and the port is expected to accumulate inventory in the fourth quarter. It's recommended to consider short - position opportunities [32]. 3.

Core Insights - The article discusses the disparity between international gold prices and domestic gold jewelry prices, highlighting that while international gold prices have dropped, domestic prices have increased due to various cost factors [1][3]. Group 1: Understanding Gold Pricing - International gold prices refer to the raw material cost of pure gold, influenced by factors such as the US dollar exchange rate, geopolitical events, and Federal Reserve policies [3]. - Domestic gold jewelry prices include not only the raw material cost but also additional costs such as processing fees, brand premiums, and store operating costs [4]. Group 2: Factors Behind Price Increases - The increase in domestic gold jewelry prices is attributed to rising non-material costs, including processing fees, brand premiums, store costs, and taxes [5]. - Processing fees for gold jewelry have risen by 20%, with costs now ranging from 50 to 150 yuan per gram due to more complex manufacturing techniques [5]. - Brand premiums can account for 10-15% of the retail price, with well-known brands charging significantly more for similar purity items [5]. Group 3: Currency and Supply-Demand Dynamics - Domestic gold prices are also affected by currency exchange rates and supply-demand relationships, which contribute to the disconnect from international prices [6]. - The recent appreciation of the US dollar has led to a situation where even if international prices drop, the domestic price in yuan may not reflect that decrease [6]. - Seasonal demand, particularly during wedding seasons and holidays, has led to increased prices as supply struggles to meet consumer demand [6]. Group 4: Consumer Guidance - Consumers are advised to differentiate between "urgent needs" and "investment" when purchasing gold, focusing on raw material prices and processing fees for urgent needs [7]. - For investment purposes, it is recommended to avoid gold jewelry due to high processing fees and instead consider gold bars or coins that are closer to raw material prices [7]. - Consumers should be cautious about market timing and avoid purchasing during peak demand periods to secure better prices [7].

Group 1 - The PTA futures market is experiencing a strong upward trend, with the main contract opening at 4434.00 CNY/ton and reaching a high of 4488.00 CNY, reflecting an increase of approximately 1.59% [1] - Major producers are reducing output due to various reasons, leading to a slight decrease in supply, while demand remains lukewarm despite the traditional peak season [1] - The processing fee for PTA is at a low level, indicating an overall undervaluation, but the long-term supply-demand outlook is pessimistic, suggesting a continuation of the current oscillating market pattern [1] Group 2 - Despite expectations of increased PTA maintenance, the polyester production load is anticipated to decline during the traditional off-peak season, resulting in a weak supply-demand outlook for PTA [2] - The cost side shows that PX loads remain high in Asia and domestically, putting pressure on PXN, while crude oil prices are fluctuating [2] - The overall supply-demand dynamics for PTA are weak, with recent news indicating a potential easing of US-China trade tensions, warranting attention to the progress of US-China economic negotiations [2]

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Polyester Industry - PX: Short - term drive is limited, with weak oscillations. Supply is expected to contract, but overall remains weak. Suggest to wait and see, focus on Brent crude oil support at $60/barrel, and conduct month - spread reverse arbitrage [1]. - PTA: Short - term drive is limited, with weak oscillations. Spot basis has weakened, but the downward space is limited. Suggest to wait and see, focus on Brent crude oil support at $60/barrel, and treat TA1 - 5 with rolling reverse arbitrage [1]. - Ethylene Glycol (MEG): Supply is abundant, with expected inventory accumulation in October and high accumulation in November - December. Suggest to short EG01 at high prices, hold the seller of call option EG2601 - C - 4250, and conduct EG1 - 5 reverse arbitrage at high prices [1]. - Short - fiber: Supply is at a high level, and terminal demand in Q4 is expected to be weak. Prices are supported in the short - term due to low inventory. Suggest the same strategy as PTA for single - side trading, and shrink the processing margin when it is above 1000 in the range of 800 - 1100 [1]. - Bottle - chip: Entering the seasonal inventory accumulation period, prices fluctuate with the cost side. Suggest the same strategy as PTA for PR single - side trading, and expect the main - contract processing margin to fluctuate between 350 - 500 yuan/ton [1]. Pure Benzene - Styrene Industry - Pure Benzene: Overall supply and demand in October are expected to be loose, with weak price drive. Suggest BZ2603 to oscillate following styrene and oil prices [2]. - Styrene: Supply will remain high, and demand support is limited. Prices are still under pressure in the short - term. Suggest to short EB12 on price rebounds [2]. Chlor - Alkali Industry - Caustic Soda: Short - term supply is increasing, and demand support is weak, with prices tending to be weak. In the medium - to - long - term, there is demand support. Suggest to short in the short - term and track downstream restocking [3]. - PVC: Supply and demand pressure is high, and the contradiction is difficult to resolve. Cost provides bottom support. Suggest to stop short - selling and wait for changes in demand [3]. Methanol Industry - Methanol: Prices may continue to oscillate. Focus on overseas device stability, customs clearance efficiency of sanctioned vessels, and actual arrival. Pay attention to port inventory reduction and overseas gas - limiting expectations [4]. Polyolefin Industry - LLDPE and PP: Supply pressure is prominent in the medium - to - long - term, and demand lacks bright spots. The 01 - contract upside is limited. Prices are under pressure due to macro - environment, cost, and supply - demand factors [6]. 3.

1. Report Industry Investment Rating The report does not explicitly provide an overall industry investment rating. However, based on the individual product outlooks, most products are expected to be in a state of "oscillation" or "oscillation on the weak side," suggesting a relatively cautious view of the energy and chemical industry [3][8][9]. 2. Core Viewpoints of the Report - China's Q3 economic data is strong, but the weakness in the energy and chemical sector mainly stems from the supply side. The good economic data provides some support to the crude oil market, but the oversupply situation remains unchanged [1]. - The export of chemical products in September generally maintained a good trend, with polyester products performing particularly well. Expanding overseas markets may be the future hope for the chemical industry [2]. - Overall, the energy and chemical industry is still anchored by crude oil and is expected to continue its weak oscillation [3]. 3. Summary by Relevant Catalogs 3.1 Market News and Macroeconomic Situation - China's Q3 GDP increased by 4.8% year - on - year, and the GDP growth rate from January to September was 5.2%. In September, the industrial added value of enterprises above designated size increased by 6.5% year - on - year, and the total retail sales of consumer goods increased by 3% year - on - year. The demand for petroleum in September increased by 6% year - on - year, continuing the positive year - on - year growth since June [1]. - The President of Ukraine stated that the Russia - Ukraine conflict will not end soon, but the pre - conditions for peace have emerged. Russia's oil transportation to India continues [8]. 3.2 Product - Specific Analysis 3.2.1 Crude Oil - **Viewpoint**: Macroeconomic factors disrupt the rhythm, and the fundamentals are continuously under pressure. - **Main Logic**: Supply is in an increasing phase dominated by the high - growth rate of OPEC+ production. Later, there will be pressure on accelerated crude oil inventory accumulation due to the peak and decline of refinery operations. Although China's inventory has decreased recently, overseas and sea - borne inventories have increased, and the inventory accumulation pressure is still being realized. The fundamental pressure persists, the geopolitical support is weakening marginally, and macro - risks are fluctuating. Oil prices are expected to continue their weak oscillation. If concerns about tariffs ease or there are temporary geopolitical risks, oil prices may rebound but the downward trend is difficult to reverse [8]. 3.2.2 Asphalt - **Viewpoint**: The asphalt futures price is testing the 3200 resistance level. - **Main Logic**: OPEC+ will continue to increase production in November, Saudi Arabia has lowered the export discount to Asia, the Middle East situation has cooled, the geopolitical premium has declined, and the positive impact of China - US negotiations remains. In the short term, crude oil has entered an oscillation mode, and asphalt futures prices will follow the oscillation of crude oil. The asphalt spot price has been continuously falling, the asphalt - fuel oil price difference is expected to continue to decline, the asphalt production plan in October has increased by 19% year - on - year, the supply shortage problem has been resolved, and the driving force supporting the high premium of asphalt has significantly weakened. The pricing power of asphalt futures is expected to return to Shandong. Under the background of negative growth in transportation fixed - asset investment, the pressure on asphalt inventory accumulation is still high. Currently, asphalt is still overvalued compared to crude oil, rebar, low - sulfur fuel oil, and high - sulfur fuel oil, and the overvalued premium is starting to decline [9]. 3.2.3 Fuel Oil - **High - Sulfur Fuel Oil** - **Viewpoint**: The fuel oil futures price has entered an oscillation mode. - **Main Logic**: OPEC+ will continue to increase production in November, Saudi Arabia has lowered the export discount to Asia, the Middle East situation has cooled. Among the three driving forces supporting high - sulfur fuel oil (the Russia - Ukraine conflict, refinery procurement, and the Palestine - Israel conflict), the Palestine - Israel conflict and the Russia - US call have a negative impact on high - sulfur fuel oil. In the short term, the fuel oil futures price will follow the oscillation of crude oil. As refinery operations increase, the demand for fuel oil processing by refineries gradually increases, but the demand for gasoline in the US is weak, the demand for residue processing is sluggish, and the peak power - generation season in the Middle East is coming to an end, so the demand for fuel oil is still weak [9]. - **Low - Sulfur Fuel Oil** - **Viewpoint**: Low - sulfur fuel oil follows the oscillation of crude oil. - **Main Logic**: Low - sulfur fuel oil has declined following crude oil, and the 3500 resistance level is effective in the short term. Low - sulfur fuel oil has strong product attributes and is facing negative factors such as a decline in shipping demand, substitution by green energy, and substitution by high - sulfur fuel oil. It is undervalued and is expected to follow the movement of crude oil. Fundamentally, the reduction of export tax rebates for refined oil products in China and the cancellation of export tax rebates for UCO have increased the supply pressure of refined oil products in China. The pressure to reduce oil and increase chemicals is likely to be transmitted to low - sulfur fuel oil, which is facing a trend of increased supply and decreased demand and may maintain a low - valuation operation [11]. 3.2.4 Chemical Products - **PX** - **Viewpoint**: Cost drags down the absolute price, but the processing margin has been repaired due to the improvement in supply - demand on a month - on - month basis. - **Main Logic**: International oil prices are generally oscillating weakly, and the cost support is weak. There is no obvious positive support from its own supply - demand, and the marginal changes in supply - demand are limited. The import volume of PX in September remained stable with narrow fluctuations. Under the situation of strong supply and demand of PX, and with the expected commissioning of PTA, there is some support for downstream demand, and the downward space for the processing margin is limited [12]. - **PTA** - **Viewpoint**: Under the expectation of new plant commissioning and restart, both the basis and the processing margin are under pressure. - **Main Logic**: The upstream cost support is average, the atmosphere in the chemical product market is cold, and PTA follows the cost to oscillate and decline. Fundamentally, supply is increasing while demand is stable. The new Fengming plant is about to be commissioned, so there is some supply pressure. The downstream polyester demand is stable, and there is more speculative replenishment at low prices. Polyester factories have enough space to offer promotions after profit repair, and the sales volume has increased slightly. The overall price mainly fluctuates following the upstream and macro - economic sentiment [12]. - **Short - Fiber** - **Viewpoint**: After the profit improvement, there is more room for profit to promote sales, the inventory has decreased on a month - on - month basis, and the support for the low processing margin has increased. - **Main Logic**: The upstream polymerization cost is not good, and the short - fiber price has declined following the cost. In terms of the supply - demand pattern, short - fiber is still generally stronger than the upstream. There is still support at the low processing margin. After the weather turns cold, orders are being placed smoothly, and the export data is strong. There is no expectation of inventory accumulation in the short - fiber industry in the short term, and there is support for demand at the end of the peak season [21]. - **Bottle Chips** - **Viewpoint**: There is not much positive support from the fundamentals, and the low price stimulates the increase in speculative replenishment demand. - **Main Logic**: The upstream polymerization cost is average, and the bottle - chip price has declined following the cost. The spot processing margin has slightly decreased. The export data of polyester bottle chips in September was average, showing a decline compared to August. The demand is in the off - season, and there is no obvious driving force for supply - demand [22]. - **Styrene** - **Viewpoint**: Crude oil is weak and inventory continues to accumulate, and styrene resumes its downward trend. - **Main Logic**: The market sentiment for pure benzene in the future is still pessimistic. With styrene's own profit at a low level, the number of maintenance operations has increased, and the supply - demand situation has slightly improved. However, the biggest current pressure is the high port inventory. As the end - of - year seasonal inventory accumulation period approaches, the concern about over - inventory persists, dragging down the performance of the industrial chain prices [17]. - **Methanol** - **Viewpoint**: The coal end provides slight support, and methanol is expected to oscillate widely. - **Main Logic**: On October 20, the methanol futures price oscillated and may continue in the short term. The production enterprises are offering discounts to sell, and the downstream purchases on demand. The price is weakly declining. The port inventory of methanol is still at a relatively high level, but considering the high probability of disturbances from Iran approaching winter, methanol still has value for long - position investment at low prices. However, it is restricted by the overall weak sentiment in the energy and chemical industry, and the weakness of downstream olefins also limits the upward space of methanol. Therefore, it is advisable to view it as oscillating in the short term [26]. - **Urea** - **Viewpoint**: The price support of individual spot goods has weakened, and the urea futures price is continuously under pressure. - **Main Logic**: On October 20, the mainstream spot prices of urea in Shandong and Hebei declined, and the downstream's follow - up purchases were cautious. Fundamentally, both supply and demand have weakened to a certain extent. The operation rate is at a relatively low level, and the agricultural demand has not improved. The pattern of strong supply and weak demand remains unchanged, and there is no effective positive support, so the futures price shows a narrow - range oscillation [27]. - **Ethylene Glycol (EG)** - **Viewpoint**: There is a lack of substantial positive factors, and it is in a low - level range adjustment without fundamental driving forces. - **Main Logic**: The overall atmosphere in the chemical product market is cold, and ethylene glycol oscillates and declines. Fundamentally, supply is increasing while demand is stable. The operation rate of ethylene glycol is at a high level, and multiple integrated plants have restarted. Although there will be maintenance operations at Shell and Fulian plants later, they are all short - term shutdowns with limited impact. The port inventory continues to accumulate gradually, and the price is still under pressure under the expectation of weakening supply - demand [18]. - **Plastic (LLDPE)** - **Viewpoint**: The oil price is still weak, and plastic oscillates on the weak side. - **Main Logic**: The oil price is still weak, the fundamental pressure persists, the geopolitical support is weakening marginally, and the macro - economic expectation is constantly fluctuating. The indication of the oil price is still pessimistic. The oil price has a limited impact on the expected US production next year, and it is still in the downward - seeking bottom stage. If there are positive macro - economic and geopolitical factors, it will rebound, but the downward trend is difficult to reverse. The fundamental support for plastic itself is still limited. It is now in the second half of the "Golden September and Silver October" period. As the peak season fades, the upstream and mid - stream still have the intention to reduce inventory at high prices, which will suppress the upward space of the price. The profit support is limited. The profit of oil - based refineries is stable under the weak oil price, the coal - based profit has slightly declined, and the profit of gas - based ethane is still good. In the short term, the futures price has slightly stabilized near the previous low, and the support strength should be monitored [31]. - **PP** - **Viewpoint**: The weakness of the oil price continues, and PP oscillates on the weak side. - **Main Logic**: The oil price oscillates weakly, the fundamental pressure persists, the geopolitical support is weakening marginally, and the macro - economic expectation is constantly fluctuating. The indication of the oil price is still pessimistic. The oil price has a limited impact on the expected US production next year, and it is still in the downward - seeking bottom stage. If there are positive macro - economic and geopolitical factors, it will rebound, but the downward trend is difficult to reverse. The fundamental support for PP itself is still limited. Currently, the production continues to increase year - on - year, but the demand support is limited, and the high - level inventory will still suppress the price performance. The profit support is limited. The profit of oil - based refineries is stable under the weak oil price, the coal - based profit has slightly declined, and the profit of gas - based ethane is still good. PP has slightly stabilized near 6600, and the focus of subsequent attention is the change in maintenance operations [32]. - **PVC** - **Viewpoint**: It has a low valuation and weak expectations, and PVC oscillates. - **Main Logic**: At the macro - level, the disturbance of China - US tariffs has resurfaced, and attention should be paid to the negotiations between the two sides at the APEC meeting. At the micro - level, the fundamentals of PVC are under pressure, and the cost is stable. Specifically, the autumn maintenance of upstream plants increased in mid - October, so the PVC production will decline; the downstream operation has recovered stage by stage, and only the low - price purchases have increased; the export order signing of PVC has improved; the operation rate of calcium carbide has decreased, and the number of PVC maintenance operations has increased, so the calcium carbide price is weakly stable; there coexist the marginal production reduction of alumina plants and the stockpiling for new plant commissioning, and the caustic soda spot may fluctuate narrowly. The static cost of PVC is 5190 yuan/ton, and the dynamic cost is expected to remain stable [35]. - **Caustic Soda** - **Viewpoint**: The spot price is stable, and the futures price oscillates. - **Main Logic**: At the macro - level, the disturbance of China - US tariffs has resurfaced, and attention should be paid to the negotiations between the two sides at the APEC meeting. At the micro - level, the medium - and long - term demand growth for caustic soda may be limited, and the production may also increase. The spot price may oscillate narrowly, manifested as: the alumina market remains in surplus, and the industry profit is poor. Recently, marginal plants have started to reduce production; the procurement by Wenfeng has relieved the pressure on 32% caustic soda in Shandong, but the caustic soda receipt volume of Weiqiao is equal to its daily consumption, and the caustic soda inventory of Weiqiao is high; the commissioning of a 4.8 - million - ton alumina plant in Guangxi in 2026 will boost the demand for caustic soda, and some factories have issued caustic soda procurement tenders; the non - aluminum operation rate is stable, and the replenishment intention is not high, and the operation rate will decline from November to December; the production of caustic soda in late October is not high, and the production will increase after the end of maintenance and new plant commissioning in the future [36]. 3.3 Product Data Monitoring - **Inter - period Spread**: The report provides the inter - period spreads of various products such as Brent, Dubai, PX, PTA, MEG, etc., along with their changes [38]. - **Basis and Warehouse Receipts**: The basis and warehouse receipts of products like asphalt, high - sulfur fuel oil, low - sulfur fuel oil, etc., are presented, as well as their changes [39]. - **Inter - product Spread**: The inter - product spreads between different products such as 1 - month PP - 3MA, 1 - month TA - EG, etc., are given, along with their changes [41].

1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Methanol - The price may continue to fluctuate under the game of supply and demand. Focus on the stability of overseas device operation, the customs - clearance efficiency of sanctioned vessels, and actual arrival performance. Pay attention to the port destocking rhythm and the implementation effect of overseas gas - limiting expectations [1]. Polyolefins (LLDPE & PP) - The inventory pressure after the holiday is still significant. The supply pressure is prominent in the medium - and long - term, and the demand lacks highlights. The upside space of the 01 contract is limited [5]. Caustic Soda - There is demand support in the medium - and long - term, but it is weak in the short term. It was previously recommended to be bearish, and now the short positions can be temporarily closed as the market stabilizes [8]. PVC - The short - term disk may continue to be under pressure. Although the supply pressure has slightly eased and exports have recovered, the demand in the peak season is weak. Pay attention to cost support and downstream demand performance [8]. PX - The supply and demand are expected to be weak in the fourth quarter. It will mainly fluctuate at a low level in the short term. It is recommended to wait and see and look for short - selling opportunities on rebounds, and mainly conduct reverse spreads on the monthly spread [9]. PTA - The short - term drive is limited, and it will mainly fluctuate at a low level. It is recommended to wait and see TA, pay attention to the support around 4500, and conduct rolling reverse spreads on TA1 - 5 [9]. Ethylene Glycol - It is expected to accumulate inventory in October, and the supply - demand structure is weak in the far - month. It is recommended to short EG01 on rallies, hold the seller of the out - of - the - money call option EG2601 - C - 4350, and conduct reverse spreads on EG1 - 5 [9]. Short Fibers - The absolute price is still under pressure in the short term, but it is relatively strong compared to raw materials due to low inventory. It is recommended to have the same strategy as PTA for the unilateral position, and widen the processing margin at a low level [9]. Bottle Chips - It is likely to enter the seasonal inventory accumulation channel. PR follows the cost end, and the processing margin improves in the short term. It is recommended to have the same strategy as PTA for the unilateral position, and the main contract processing margin is expected to fluctuate between 350 - 500 yuan/ton [9]. Pure Benzene - The overall supply and demand in October are expected to be loose, and the price drive is weak. BZ2603 follows the fluctuations of styrene and oil prices [10]. Styrene - The supply - demand is expected to be loose, and the price is still under pressure in the short term. EB11 should be treated as a short - selling opportunity on rebounds [10]. 3.

1. Report Industry Investment Rating The report does not explicitly mention an overall industry investment rating. However, for different energy and chemical products, the mid - term outlooks are provided, including "weak and volatile", "volatile", and "weak - trending with volatility". 2. Core Viewpoints of the Report - Coal price increases support the coal - chemical industry, while China's port fees on US - related vessels negatively impact US crude oil physicals. The contrast between strong coal and weak oil prices makes the hedging between coal - chemical and oil - chemical industries potentially valuable again [2][3]. - For coal - chemical products, PVC, methanol, and urea are considered for long - positions, with PVC potentially being more stable in terms of cost. For oil - chemical products, olefins are short - positions, and the new styrene production device may face challenges due to high inventory [3]. - Overall, the energy and chemical market still takes crude oil as a reference and is expected to continue its weak - trending with volatility [4]. 3. Summary by Relevant Catalogs 3.1 Market Situation and Outlook - **Crude Oil**: Macro - factors affect the rhythm, and the fundamentals are continuously under pressure. The EIA data shows that US crude oil inventories have accumulated, and refinery operating rates have declined. The global supply is in an increasing period, and there is pressure for accelerated crude oil inventory accumulation. The price is expected to be weak and volatile [10]. - **Asphalt**: The decline has slowed, and the asphalt futures price is expected to be volatile. The geopolitical premium of crude oil has declined, and the supply of asphalt has increased, with high inventory pressure. The absolute price of asphalt is over - valued [12]. - **High - Sulfur Fuel Oil**: The fuel oil futures price has entered a volatile mode. The reduction of geopolitical factors and the increase in supply have affected the price, and it is expected to be volatile [12]. - **Low - Sulfur Fuel Oil**: It follows the crude oil price and is volatile. It faces negative factors such as a decline in shipping demand and substitution, and is expected to maintain a low - valuation operation [14]. - **Methanol**: Slightly boosted by coal, it is in a wide - range volatile state. There is still value in going long at a low level, but the upside space is limited [25][26]. - **Urea**: The spot price is firm, but the futures price is under pressure. The supply - demand pattern is still supply - strong and demand - weak, and it is expected to be volatile [26][27]. - **Ethylene Glycol (EG)**: Supported by coal prices, it rebounds at a low level, but the supply - demand pattern is still under pressure. The inventory is increasing, and the price is expected to be weak and volatile [20][22]. - **PX**: The futures price stops falling and rebounds, but the increase is limited, and the profit is repaired month - on - month. It is expected to fluctuate with costs and macro - sentiment [15]. - **PTA**: New devices are about to be put into production, and the processing fee is under pressure. It is expected to follow the cost and be weak and volatile [15]. - **Short - Fiber**: Downstream speculative stocking promotes inventory reduction. The supply - demand is relatively healthy in the short term, and the processing fee is stable. It can consider long - short hedging operations [22]. - **Bottle Chip**: The improvement of the processing fee stimulates the moderate increase of production. The absolute price follows the upstream cost, and the profit has support at the bottom [23][24]. - **Propylene (PL)**: Affected by weak oil prices and macro - factors, it is weak and volatile [31]. - **PP**: Affected by weak oil prices, it continues to decline. The high inventory suppresses the price, and it is expected to be weak and volatile [30]. - **Plastic**: There is slight support near the previous low, and it is weak and volatile. The fundamental support is limited, and the upper - middle reaches have the intention to reduce inventory [29]. - **Styrene**: Affected by commodity sentiment and device news, it shows a "V" - shaped trend. The high inventory is the main pressure, and it is expected to try to widen the profit [19][20]. - **PVC**: With low valuation and weak expectations, it is volatile. The fundamentals are under pressure, and the cost is moving down, and it is expected to be weak [32]. - **Caustic Soda**: The spot price is stable, and the futures price is volatile. The short - term supply - demand has improved, but the upward driving force is insufficient [32][33]. 3.2 Variety Data Monitoring - **Inter - period Spread**: The report provides the inter - period spreads of various varieties such as Brent, Dubai, PX, PTA, etc., and their changes [34]. - **Basis and Warehouse Receipts**: It shows the basis, its changes, and the number of warehouse receipts for varieties like asphalt, high - sulfur fuel oil, low - sulfur fuel oil, etc. [35]. - **Inter - variety Spread**: The inter - variety spreads between different products such as PP - 3MA, TA - EG, etc., and their changes are presented [37].

Core Viewpoint - The polyester industry chain has been under price pressure since early September, with PTA futures showing weak performance and prices stabilizing around 4500 yuan/ton after the National Day holiday [1] Supply Side - As of early October, PTA weekly capacity utilization has increased by approximately 7 percentage points compared to the end of August, reaching 77.84%, while PX weekly capacity utilization rose to 88.23%, up about 3.6 percentage points [1][3] - Several major facilities remain offline, with uncertain restart dates, including the 1.2 million ton facility at Sanfangxiang and the 2.25 million ton facility at Yisheng Dalian [3] - There are expectations for maintenance in October for the 1 million ton facility at Sichuan Nengtou and the 2.5 million ton facility at Dushan Energy in November, indicating limited recovery in PTA capacity utilization despite marginal increases [3] Demand Side - As of early October, demand from weaving terminals remains strong, with improved inquiry atmosphere for autumn and winter home textiles and apparel fabrics, although foreign trade orders are still low [4] - The average capacity utilization for long filaments is approximately 91.39%, and for short fibers, it is about 86.96%, both showing slight increases compared to August [4] - The overall demand performance is moderate, with limited new orders during the National Day holiday, leading to a cautious approach in raw material procurement [4] Price and Profitability - From early September to early October, processing profits in the polyester industry chain have decreased, with PX valuations dropping and PTA processing fees remaining low [2] - As of early October, the weighted profit for polyester is a monthly loss of 26 yuan/ton, significantly narrowing from a loss of 80 yuan/ton in August [2] - The expected trading range for PTA futures is between 4400 to 4800 yuan/ton, with spot processing fees anticipated to range from 100 to 300 yuan/ton [4]
