1. Report Industry Investment Rating - The investment rating for pure benzene is neutral to bearish [4] - The investment rating for styrene is also neutral to bearish [6] 2. Core Views Pure Benzene - Supply: This week, the operating rate of pure benzene increased slightly, with supply rising and significant domestic supply pressure. There are few planned maintenance activities, and future supply is expected to remain at a high level. Ship reports indicate a large number of arrivals in the first 10 days of November, and the overall import volume in November is expected to be high [4] - Demand: The main downstream product, styrene, has low profit margins, leading to many planned future maintenance activities. The overall operating rate of downstream industries has declined again, and demand is expected to remain low in the short term [4] - Inventory: With a large number of incoming ships, port inventory is expected to accumulate in November [4] - Valuation: The BZN spread is low, indicating that the valuation of pure benzene is low [4] - Outlook: There is a mismatch between supply and demand for pure benzene, but the improving gasoline blending demand in Europe and the United States may provide some support. Future demand for pure benzene is expected to be weak, and combined with high supply, the fundamentals are expected to remain weak in the short term. OPEC+ has announced a suspension of production increases in the first quarter of next year, and a potential inflection point may occur in the first quarter of next year [4] Styrene - Supply: Due to a large number of maintenance activities, both the operating rate and production of styrene have declined, and the overall future supply is expected to be low [6] - Demand: The overall downstream demand has decreased, and the overall operating rate has declined. There are new PS installations in operation, and new ABS installations may come online in mid - November. The finished product inventory pressure in downstream industries remains, and demand is expected to recover slowly [6] - Inventory: With many styrene maintenance activities, overall inventory is expected to decrease in November [6] - Valuation: The BZ - SM spread is low, indicating that the valuation of styrene is low [6] - Outlook: Styrene supply has tightened significantly, and inventory may decrease in November. Considering the overseas gasoline blending support for pure benzene, styrene is expected to trade sideways in the short term. Some far - month spreads have reached a risk - free level, which is worth attention [6] 3. Summary by Relevant Catalogs Pure Benzene Supply - The operating rate of pure benzene has been at a high level, and the supply is abundant. There were new maintenance activities at Zhongyuan Ethylene last week. Looking at the annual data, the supply situation is relatively stable, with the total supply in 2025 ranging from 252.88 to 280.26 million tons in different months [4][14][50] - Many enterprises have ongoing or planned maintenance, such as Changyi Petrochemical, Jincheng Petrochemical, etc., with some having undetermined restart times [15] Demand - The overall operating rate of downstream industries is expected to decline, and the profit margins remain low. The main downstream products, including styrene, caprolactam, adipic acid, etc., have shown varying degrees of demand weakness [4][16][27] Inventory - Last week, the inventory at East China ports was 11.9 million tons, a month - on - month increase of 2.4 million tons. From the monthly data, the inventory is expected to accumulate from November to December, with the port inventory change showing an upward trend in some months [43][50] Valuation - The BZN spread is low, indicating a low valuation of pure benzene [43] External Market Support - The US - Asia arbitrage window has been closed, but the overseas gasoline blending demand may provide some support. In different regions, the demand for pure benzene varies: in North America, chemical demand is weak but gasoline blending demand is good; in Western Europe, demand is weak; in Asia, supply is sufficient, and the consumption of three S products is weak [44][49] Styrene Supply - The supply of styrene in November is expected to decline due to a large number of maintenance activities. There were no new maintenance installations last week, and supply in November and December is expected to be low [54][58] - Many enterprises have carried out or planned maintenance, such as Zhenhai Liande Phase II, Satellite Petrochemical, etc. [56] Demand - The overall downstream demand has decreased, but the profit margins of downstream industries are relatively good. The consumption of downstream products such as ABS, EbS, etc., shows different trends in different months [6][72][93] Inventory - As of now, the inventory at East China ports has decreased to 17.48 million tons, and at South China ports to 2.1 million tons. With the reduction in overall supply, inventory is expected to continue to decline [91] Valuation - The BZ - SM spread is low, indicating a low valuation of styrene [6] External Market Support - In Western Europe, demand is weak, and in Asia, demand is also relatively weak [7]

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Viewpoints of the Report - The energy and chemical sector remains weak, with the downward trend driven by the over - capacity of the chemical industry, the decline in crude oil costs, and the short - selling of market funds. Most varieties have seen a decline of over 10% since mid - September, and short positions can still be held [1][2] Group 3: Summary by Relevant Catalogs (1) Crude Oil - Logic: Geopolitical influence on crude oil is weakening, and the macro - drive is bearish. The main reason for the downward trend is the excess supply. OPEC + has increased production, and inventories have been rising. The downward trend continues, and attention should be paid to whether the April low can be broken [3] - Technical Analysis: The daily - level and hourly - level structures are both in a downward trend. The intraday performance is weak, and the short - position should be held with the short - term pressure at 447 for the 12 - contract [3] (2) Styrene (EB) - Logic: Although the supply - demand situation has slightly improved due to increased maintenance, port inventories are still accumulating, and there is a risk of price collapse due to the approaching seasonal inventory accumulation in January. Do not chase short positions [5][8] - Technical Analysis: The hourly - level structure is in a downward trend. The intraday rebound is limited, and the short - position should be held with the short - term pressure at 6610 [8] (3) Rubber - Logic: The supply in Southeast Asia is expected to increase in the fourth quarter, and domestic inventories are high. The cost support is weakening [10] - Technical Analysis: The daily - level and hourly - level structures are in a downward trend. The intraday increase is a rebound. The short - position should be held with the stop - profit at 15450 [10] (4) Synthetic Rubber (BR) - Logic: The supply - demand contradiction is not obvious in the short term, but the cost of crude oil and butadiene is declining, which may drive the price of synthetic rubber down [12][14] - Technical Analysis: The daily - level and hourly - level structures are in a downward trend. The intraday increase is a rebound. The short - position should be held with the stop - profit at 11300 [14] (5) PX - Logic: The supply - demand situation has slightly improved, but the high - supply pattern remains. The main driving factor is the cost of crude oil [18] - Technical Analysis: The hourly - level structure is in a downward trend. The intraday rebound is limited. The short - position should be held with the stop - profit at 6460 - 6480 [18] (6) PTA - Logic: The supply pressure is large, and the demand is stable. The main driving factor is the cost of crude oil [20] - Technical Analysis: The hourly - level structure is in a downward trend. The intraday rebound is limited. The short - position should be held with the stop - profit at 4470 [20] (7) PP - Logic: The supply pressure is high, and the demand is weak both at home and abroad. The cost is also under downward pressure [22] - Technical Analysis: The hourly - level structure is in a downward trend. After taking profit, there is no good entry point, so continue to wait and see [22] (8) Methanol - Logic: There is a long - position opportunity for the 01 - contract in the future due to seasonal factors, but the short - term supply is high and inventories are high. Pay attention to the technical signal and the gas - restriction time in Iran [26] - Technical Analysis: The daily - level and hourly - level structures are in a downward trend. The short - position should be held with the stop - profit at 2320. Consider long - position after breaking through the pressure [26] (9) PVC - Logic: The supply is high, the demand from the real - estate sector is low, and the inventory is accumulating [29] - Technical Analysis: The daily - level and hourly - level structures are in a downward trend. The short - position should be held with the short - term pressure at 4800 [29] (10) Ethylene Glycol (EG) - Logic: The supply is increasing, and the inventory is accumulating, indicating a weakening supply - demand situation [30] - Technical Analysis: The daily - level and hourly - level structures are in a downward trend. The short - position should be held with the short - term pressure at 4060 [30] (11) Plastic - Logic: The supply pressure is increasing, and the demand is weak. The cost is under downward pressure [32] - Technical Analysis: The daily - level and hourly - level structures are in a downward trend. The short - position should be held with the short - term pressure at 6940 [32] (12) Soda Ash - Logic: The supply and inventory are high, the demand is not expected to improve, and the macro - drive is downward. The downward pressure on the price continues [36] - Technical Analysis: The hourly - level structure is in a downward trend. The short - position should be held with the short - term pressure at 1260 [36] (13) Caustic Soda - Logic: The supply pressure is increasing in the medium - term, and the demand is stable. The driving force is bearish [37] - Technical Analysis: The hourly - level structure is in a downward trend. After taking profit, there is no good entry point, so continue to wait and see [39]
