Report Industry Investment Ratings - Propylene, Polypropylene, Styrene, PVC, Methanol: ★☆☆ (One star, indicating a bullish/bearish bias with a driving force for price increase/decrease, but limited operability on the trading floor) [1] - PTA, Ethylene Glycol, Short Fiber, Bottle Chip, Urea, Caustic Soda, Glass: ☆☆☆ (White star, indicating a relatively balanced short - term bullish/bearish trend and poor operability on the trading floor, suggesting waiting and seeing) [1] - Pure Benzene: Not rated in the table, but with analysis in the report [3] - PX: ☆☆☆ [1] - Soda Ash: The symbol in the table is unclear [1] Core Viewpoints - The chemical market shows a mixed trend, with different products having different price trends and supply - demand situations. Some products are affected by factors such as inventory, cost, demand, and policies, and their short - term and medium - term trends vary [2][3][5] Summary by Related Catalogs Olefins - Polyolefins - Propylene futures rose, with controllable enterprise inventories and stable offers. Downstream follow - up was okay, and the trading range was stable [2] - Polyethylene futures rose, but the market was waiting for news, with cost support weakening and supply pressure. Sellers mostly offered small discounts [2] - Polypropylene futures rose. Although the supply pressure decreased due to more upstream maintenance, the demand improvement in the peak season was limited, and the high - level inventory was slowly digested. The supply - demand contradiction may increase, and the price may remain low for a long time [2] Pure Benzene - Styrene - Pure benzene futures prices rebounded above 5500 yuan/ton. The spot price in East China rebounded, and the low - level transactions in Shandong improved. The short - term price may rebound, but the high import volume in the medium term is the main pressure [3] - Styrene futures rose, but there were only expected device shutdowns. The inventory remained high, and the upward price momentum was limited [3] Polyester - PX and PTA rebounded with reduced positions. The short - term price may continue to rebound, mainly depending on oil prices. In the medium term, with the weakening demand and expected inventory accumulation, the strategy is mainly reverse arbitrage [5] - Ethylene glycol rebounded with increased positions. The short - term price has a rebound expectation, but there is still inventory accumulation pressure in the medium term, suggesting shorting at high prices [5] - Short fiber continued to be a bullish allocation. The new production capacity was limited, the inventory was decreasing, and the downstream备货 sentiment was improved [5] - Bottle chip demand weakened, with inventory accumulation and pressure on processing margins. The long - term pressure is over - capacity [5] Coal Chemical Industry - Methanol fluctuated at a low level. The short - term coastal market may fluctuate within a range, and the price may be bullish in the medium - to - long term as the import supply pressure is expected to decrease [6] - Urea futures prices rose slightly. The short - term market is expected to fluctuate strongly within a range, supported by the marginal improvement of supply - demand and coal prices [6] Chlor - Alkali - PVC showed a fluctuating trend. The supply may increase, and it may operate at the bottom range due to weak domestic demand and potential export policy pressure [7] - Caustic soda fluctuated narrowly. The supply fluctuated slightly, and it is recommended to be cautious when shorting due to non - aluminum downstream restocking and a high basis [7] Soda Ash - Glass - Soda ash fluctuated strongly. The supply was still high, and it is recommended to short at high prices after a rebound [8] - Glass fluctuated narrowly. The inventory continued to accumulate, and the downward range is expected to be limited. It is advisable to pay attention to selling out - of - the - money put options [8]

Report Summary 1) Report Industry Investment Rating - Not provided in the content 2) Core Viewpoints of the Report - PTA supply is shrinking, but its processing fee remains low due to over - capacity from new device production. With the end of the peak season and concerns about trade - war impacts on textile demand, PTA's operating rate may decline further, and it's difficult to have an independent market due to falling crude oil prices [2] - For ethylene glycol, port inventory in East China is low, but domestic device production and expected decline in overseas imports put pressure on prices. With the end of the polyester peak season and a weakening crude oil fundamental, polyester is expected to run weakly [2] 3) Summary by Relevant Catalogs a.

Report Industry Investment Ratings No relevant content provided. Core Views Polyolefins - The supply of PE is increasing steadily, with significant profit improvement, continuous increase in the operating rate, and limited planned maintenance. Overseas inventory clearance at the end of the year also brings impacts, highlighting long - term supply pressure. PP's valuation has been significantly repaired due to the sharp decline in propane and crude oil. Although there are more recent overhauls in PP, the new device commissioning pressure in October is large, and the demand side lacks bright performance. The supply - demand structure of polyolefins is loose, and the upside space of the 01 contract is limited. Overall, the macro - environment is pessimistic, and the prices of PP and PE face pressure [2]. Methanol - At the port, due to sanctions, some warehouses do not accept sanctioned vessels, increasing the willingness to hold spot goods. Coupled with supply - side disturbances, the port basis has strengthened significantly. Overseas production has declined, and some devices have stopped. In late October, attention should be paid to the expected supply reduction caused by overseas gas restrictions. Inland supply has a certain bottom - support for prices due to a relatively healthy inventory structure. The demand side is weak. Overall, the price may continue to fluctuate under the supply - demand game, and attention should be paid to the port de - stocking rhythm and the implementation effect of overseas gas - restriction expectations [4]. Benzene - Styrene - For pure benzene, although there are device overhauls, there are also new production capacity commissioning expectations, and the domestic supply is expected to remain at a relatively high level. The downstream demand support is limited, and the inventory in East China ports may continue to decline. The price drive is weak in October. For styrene, under the double pressure of inventory and industry profit, some devices are under overhaul, but new devices are about to be commissioned, and the overall supply will remain high. The demand side support is also limited, and the price drive is weak. In the short - term, the price is still under pressure [6]. Polyester Industry Chain - For PX, the supply has shrunk compared to expectations due to unexpected overhauls or load reductions of some devices, while the demand has increased. However, overall, the supply - demand is still weak, and the price is in a weak oscillation. For PTA, the spot basis continues to weaken, but the downward space is limited. The absolute price is also in a weak oscillation. For short - fiber, the price is supported in the short - term, but the cost - side support is weak. For bottle - chips, it is likely to enter a seasonal inventory accumulation period, and it follows the cost - side fluctuations. For ethylene glycol, the domestic supply is abundant, and it is expected to accumulate inventory in October, with the upper price limit under pressure [7]. PVC and Caustic Soda - For caustic soda, the demand support from the aluminum industry is weak in the short - term, but there may be long - term demand support. The supply is increasing in the short - term, and the price is weak. For PVC, the supply - demand pressure is large, the fundamental contradiction is difficult to resolve, and the price is weak. The cost - side provides bottom support, and short - term short positions can stop profit [8].

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.

The PTA plant maintenance is insufficient, the operating rate remains at a medium - high level, and the expected new plant commissioning will intensify the supply - loose pattern. The decline in the crude oil price center weakens the PX cost support, and the PX processing fee is expected to be compressed, which may force the PTA cost line to sink [2]. - **Demand**: The polyester factory operating rate is restricted by the weak terminal orders. The 15 - day average turnover of China Textile City decreased by 23.7% month - on - month, and the falsification of peak - season demand accelerates the negative feedback transmission in the industrial chain. The low sales rate of polyester filament suppresses the polyester operating elasticity, and the marginal driving force on the PTA demand side is further weakened [3]. - **Inventory**: The PTA factory inventory has exceeded the high point of the same period in the past three years, and the social inventory days have climbed to 7 - 8 days. The continuous weakening of the inter - month spread reflects the intensifying inventory - accumulation pressure. In the low - processing - fee environment, the factory's price - support ability is weakened, and the high inventory may force the plant to reduce production in advance, but the pattern of strong supply and weak demand is difficult to change in the short term [3]. 3.1.2 Polyester - **Price**: On October 20, the short - fiber main contract closed at 6,028.0 yuan/ton, down 0.13% from the previous trading day. The spot price in the East China market was 6,285.0 yuan/ton, down 5.0 yuan/ton, with a basis of 257.0 yuan/ton [4]. - **Demand**: The MA15 turnover of China Textile City decreased from 851.8 million meters on October 10 to 855.87 million meters on October 20, indicating weak terminal textile demand [4]. - **Inventory**: The inventories of polyester staple fiber (6.11 days), polyester filament DTY (31.5 days), and FDY (26.1 days) are all higher than the 5 - year average values (4.96/28.42/22.19 days). The inventory pressure of DTY is significant, and although the POY inventory (16.8 days) is lower than the average of 20.40 days, the de - stocking rhythm is blocked [4]. 3.2 Industrial Chain Price Monitoring - **PX**: The main contract price of PX futures decreased by 0.38%, the trading volume increased by 36.35%, and the open interest increased by 10.50%. The spot prices in China's main port CFR and South Korea FOB remained unchanged [5]. - **PTA**: The main contract price of PTA futures decreased by 0.41%, the trading volume increased by 14.03%, and the open interest increased by 4.00%.

The spot price in the East China market decreased slightly, and the PF 1 - 5, 9 - 1 spreads increased, while the 5 - 9 spread decreased [5]. - **Other products**: The prices of Brent crude oil, WTI, CFR Japan naphtha, ethylene glycol, polyester chips, and most polyester filaments remained unchanged, while the price of polyester bottle chips decreased by 0.27% [5]. - **Processing spreads**: The processing spreads of naphtha, PX, polyester chips, and most polyester filaments remained unchanged, while the PTA processing spread decreased by 1.26%, and the polyester bottle chip processing spread decreased by 6.36% [6]. - **Light - textile city turnover**: The total turnover on October 20 was 653 million meters, a month - on - month decrease of 25.03%. The turnover of long - fiber fabrics decreased by 19.48%, and that of short - fiber fabrics decreased by 42.79% [6]. - **Industrial chain load rate**: The operating rates of PTA factories, polyester factories, and Jiangsu - Zhejiang looms remained unchanged [6]. - **Inventory days**: The inventory days of polyester staple fiber decreased by 19.39%, while those of POY, FDY, and DTY increased by 23.53%, 8.30%, and 9.00% respectively [6]. 3.3 Industry Dynamics and Interpretation 3.3.1 Macroeconomic Dynamics - On October 20, Fed's Musalem said that if employment faces more risks and inflation is under control, he may support another interest - rate cut. The Israel - Hamas conflict continued with various statements and actions from both sides [7]. - On October 17, various Fed officials had different views on interest - rate cuts. The World Gold Council research head said the gold market was not saturated, and the Shanghai Gold Exchange called for risk control [7]. 3.3.2 Supply - Demand - Demand On October 20, the total turnover of China Textile City was 653.0 million meters, a month - on - month decrease of 25.03%, with 529.0 million meters of long - fiber fabric turnover and 123.0 million meters of short - fiber fabric turnover [9]. 3.4 Appendix - Analysis of Future Price Trends - **Supply side**: PX and PTA may have sufficient supply. The high operating rate of PX and PTA plants and the expected new capacity may lead to an oversupply situation. The decline in crude oil prices may reduce PX costs, but the impact on supply also depends on refineries' production willingness [36]. - **Demand side**: The turnover of China Textile City has declined, indicating weak polyester demand. The weak downstream demand may lead to a decline in polyester operating rates, which in turn suppresses PTA prices [37]. - **Inventory side**: The high PTA factory inventory indicates great inventory - accumulation pressure. The combination of high supply, weak demand, and high inventory may lead to further inventory accumulation and price suppression [37].

Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core Views of the Report - PTA supply side is contracting, with Ningbo Yisheng Petrochemical Phase 4 reducing its load by 50% until the end of the month. PTA processing fees remain low, and industry profits are still constrained by over - capacity due to new plant commissions. [2] - Polyester downstream load remains above 90%, but high load has not led to large - scale inventory accumulation. With the end of the "Golden September and Silver October" period, there are concerns that subsequent textile and clothing demand will be affected by the trade war. [2] - PTA's operating rate may decline further, and due to the decline in crude oil prices, it is difficult for PTA to have an independent market. Bottle chips and short fibers continue to fluctuate with costs.

Report Summary 1) Report Industry Investment Rating No information provided. 2) Core View of the Report - PTA supply is shrinking, with Ningbo Yisheng Petrochemical Phase 4 reducing its load by 50% until the end of the month. However, its processing fee remains low due to over - capacity from new device production. The polyester downstream load is high, but there are concerns about textile and clothing demand after the "Golden September and Silver October" period due to trade wars. PTA's upward movement is restricted by falling crude oil prices [2]. - For ethylene glycol, the inventory at East China ports is low, and the expected import volume from overseas markets is decreasing. However, domestic device production is putting pressure on prices. With the end of the polyester peak season and the downward movement of the crude oil fundamentals, polyester is expected to operate weakly [2]. 3) Summary by Relevant Catalogs Market Quotes - **PTA**: The price of INE crude oil rose from 432.6 yuan/barrel to 435.8 yuan/barrel, PTA - SC decreased from 1258.3 yuan/ton to 1217.0 yuan/ton, and the PTA/SC ratio dropped from 1.4002 to 1.3843.
