With the gradual mass production of new production capacity, the long - term supply pressure is still large [4]. - Demand side: The production start - up of downstream products remains at a low level, and enterprises maintain just - in - time procurement. The export signing and delivery volume increase week - on - week. Affected by the rush to export before the implementation of anti - dumping duties, the PVC export in July exceeded expectations. After India announced an increase in anti - dumping duties, the rush to export is expected to continue, and the export expectation in the fourth quarter weakens [4]. - Inventory: The social inventory continues to accumulate and is relatively high year - on - year. The 09 contract has a large warehouse receipt pressure [4]. - Cost: The prices of coal and ethylene have strengthened recently, and their impact on the PVC cost needs to be continuously monitored [4]. Caustic Soda - Supply side: The maintenance of chlor - alkali enterprises increases, and the production start - up rate decreases month - on - month, but it is still at a high level in the same period. The production start - up in Shandong increases slightly, also at a high level in the same period. After the maintenance of Yantai Wanhua, the production start - up may decline slightly [4]. - Demand side: The profit of alumina is good, and the production start - up is stable month - on - month. The delivery volume of caustic soda to alumina plants, the main downstream, gradually increases, and the spot price remains stable. The non - aluminum downstream production start - up increases slightly month - on - month, and the procurement is acceptable. Affected by the military parade in late August, the transportation of caustic soda is restricted, and the factory inventory may accumulate later. With the approaching of the peak season expectation, the pending orders in Shandong are acceptable [4]. - Cost and profit: The price of liquid chlorine is weak, but there is still cost support. The chlor - alkali profit is at a medium level in the same period [4]. Strategy PVC - Single - side: Wait and see [5][6] - Inter - period: Wait and see; for SH10 - 01, consider a long - spread strategy when the price difference is low [5][6] - Inter - variety: No strategy [5][6]

Coupled with the gradual mass production of new production capacity, the PVC output is expected to continue to rise, and the supply - side pressure is still high [3] - Demand side: The operation rate of downstream products remained at a low level, and enterprises maintained rigid procurement. The export orders decreased month - on - month. India announced a new anti - dumping duty on imported PVC, with a general increase of 46 - 52 US dollars/ton in the Chinese mainland compared with the previous level. There is expected to be a rush to export in September, and the export is expected to weaken after September [3] - Inventory: The social PVC inventory continued to accumulate, and the absolute inventory value was high. The warehouse receipts continued to increase, and the pressure of the 09 contract warehouse receipts was large. The chlor - alkali profit still has room for compression, and the supply - demand situation remains weak [3] Caustic Soda - Supply side: The upstream operation rate remained at a high level, and the operation rate in Shandong was also high. However, some local enterprises had device load reduction situations, and combined with the planned maintenance of Wanhua in Yantai, the operation rate may decline slightly in the later period. Attention should be paid to the operation rate in Shandong from late August to September [4] - Demand side: The profit of alumina was good, and the operation rate was stable month - on - month. The delivery volume of caustic soda to the main downstream alumina plants was lower than the daily consumption, and downstream manufacturers raised the purchase price, causing the spot price to continue to rise. The non - aluminum operation rate increased slightly month - on - month, and the procurement was acceptable. Affected by the military parade in mid - to - late August, the transportation of caustic soda was restricted, and downstream enterprises stocked up in advance, improving the market sentiment. With the approaching of the peak season, the pending orders in Shandong were acceptable, and the enterprise inventory pressure decreased [4] - Future attention points: Attention should still be paid to the restocking rhythm of downstream enterprises during the "Golden September and Silver October" peak season and the production capacity release rhythm of alumina in Guangxi. The subsidy for liquid chlorine increased, and the cost support still exists. The comprehensive chlor - alkali profit is at a medium level compared with the same period [4] Strategy PVC - Unilateral: Neutral - Inter - period: Wait and see - Inter - commodity: None [5] Caustic Soda - Unilateral: Cautiously bullish - Inter - period: Go long on SH10 - 01 at low prices - Inter - commodity: None [6]

Group 1: Report Industry Investment Ratings - PVC: Cautious short-selling hedging [4] - Caustic soda: Neutral [4] Group 2: Core Views of the Report - The macro atmosphere for PVC has faded, and the market is mainly trading based on fundamentals. The supply is increasing due to restarted devices and new capacity, while demand is weak both domestically and externally, leading to continued inventory accumulation and potential compression of chlor-alkali comprehensive profits [3]. - For caustic soda, the price of liquid chlorine in Shandong has stabilized and rebounded, and the overall supply is expected to remain high. Demand lacks continuous support, and the inventory in factories is increasing. The chlor-alkali comprehensive profit still has room for compression, and the upward movement of the futures price is limited [3]. Group 3: Summary by Related Catalogs PVC Market News and Important Data - Futures price and basis: The closing price of the PVC main contract was 4,955 yuan/ton (+21), with an East China basis of -105 yuan/ton (-21) and a South China basis of -115 yuan/ton (-21) [1]. - Spot price: The East China calcium carbide method was quoted at 4,850 yuan/ton (+0), and the South China calcium carbide method was quoted at 4,840 yuan/ton (+0) [1]. - Upstream production profit: The semi-coke price was 535 yuan/ton (+0), the calcium carbide price was 2,825 yuan/ton (+0), the calcium carbide profit was 107 yuan/ton (+0), the gross profit of PVC calcium carbide method production was -445 yuan/ton (+107), the gross profit of PVC ethylene method production was -621 yuan/ton (+74), and the PVC export profit was -5.7 US dollars/ton (+6.2) [1]. - Inventory and operation: PVC factory inventory was 38.2 tons (-0.5), PVC social inventory was 39.3 tons (+2.0), the PVC calcium carbide method operation rate was 77.52% (+0.59%), the PVC ethylene method operation rate was 68.31% (-1.92%), and the PVC operation rate was 74.97% (-0.10%) [1]. - Downstream orders: The pre-sales volume of production enterprises was 69.0 tons (+3.2) [1]. Market Analysis - Supply: Some devices have restarted, and the intensity of maintenance has weakened, with high production volume. The new production capacity of Bohua and Wanhua Fujian, totaling 900,000 tons, is expected to be put into production, increasing supply pressure [3]. - Demand: It is the off-season for domestic downstream demand, and the operation rate of downstream products is at a low level compared to the same period. Domestic demand remains weak, and export orders have declined month-on-month. The Indian BIS policy has been extended for 6 months, and the anti-dumping policy has not been implemented. If implemented, it may affect PVC exports [3]. - Inventory: PVC social inventory continues to accumulate [3]. Caustic Soda Market News and Important Data - Futures price and basis: The closing price of the SH main contract was 2,484 yuan/ton (+18), and the basis of 32% liquid caustic soda in Shandong was 141 yuan/ton (-18) [1]. - Spot price: The price of 32% liquid caustic soda in Shandong was 840 yuan/ton (+0), and the price of 50% liquid caustic soda was 1,370 yuan/ton (+0) [2]. - Upstream production profit: The single-product profit of caustic soda in Shandong was 1,634 yuan/ton (+0), the comprehensive profit of chlor-alkali in Shandong (0.8 tons of liquid chlorine) was 690.8 yuan/ton (+0.0), the comprehensive profit of chlor-alkali in Shandong (1 ton of PVC) was 425.78 yuan/ton (-10.00), and the comprehensive profit of chlor-alkali in the Northwest (1 ton of PVC) was 1,368.33 yuan/ton (+0.00) [2]. - Inventory and operation: Liquid caustic soda factory inventory was 38.39 tons (+0.96), flake caustic soda factory inventory was 2.40 tons (+0.04), and the caustic soda operation rate was 82.60% (+2.20%) [2]. - Downstream operation: The alumina operation rate was 83.28% (+1.72%), the printing and dyeing operation rate in East China was 58.89% (+0.00%), and the viscose staple fiber operation rate was 84.55% (+6.75%) [2].

Caustic soda's upward space may be limited, and its later performance is affected by the price trend of liquid chlorine [3][4] Summary by Related Catalogs Market News and Important Data PVC - Futures price and basis: The closing price of PVC's main contract is 4,892 yuan/ton (-14), the East China basis is -112 yuan/ton (+4), and the South China basis is -62 yuan/ton (-16) [1] - Spot price: The East China calcium carbide - based PVC is quoted at 4,780 yuan/ton (-10), and the South China calcium carbide - based PVC is quoted at 4,830 yuan/ton (-30) [1] - Upstream production profit: The semi - coke price is 575 yuan/ton (+0), the calcium carbide price is 2,875 yuan/ton (-5), the calcium carbide profit is 125 yuan/ton (-5), the gross profit of PVC's calcium carbide method is -552 yuan/ton (-48), the gross profit of PVC's ethylene method is -695 yuan/ton (-2), and the PVC export profit is -9.0 US dollars/ton (-1.6) [1] - PVC inventory and operation: The in - factory inventory of PVC is 38.6 tons (-0.9), the social inventory is 37.3 tons (+1.1), the operation rate of PVC's calcium carbide method is 80.73% (+0.30%), the operation rate of PVC's ethylene method is 65.46% (-1.92%), and the overall operation rate is 76.50% (-0.31%) [1] - Downstream order situation: The pre - sales volume of production enterprises is 65.8 tons (+2.8) [1] Caustic Soda - Futures price and basis: The closing price of SH's main contract is 2,408 yuan/ton (+28), and the basis of Shandong's 32% liquid caustic soda is 61 yuan/ton (+35) [1] - Spot price: Shandong's 32% liquid caustic soda is quoted at 790 yuan/ton (+20), and Shandong's 50% liquid caustic soda is quoted at 1,270 yuan/ton (+20) [2] - Upstream production profit: The single - variety profit of Shandong's caustic soda is 1,478 yuan/ton (+63), the comprehensive profit of Shandong's chlor - alkali (0.8 tons of liquid chlorine) is 374.5 yuan/ton (-137.5), the comprehensive profit of Shandong's chlor - alkali (1 ton of PVC) is 139.53 yuan/ton (+59.50), and the comprehensive profit of Northwest's chlor - alkali (1 ton of PVC) is 1,294.03 yuan/ton (+0.00) [2] - Caustic soda inventory and operation: The inventory of liquid caustic soda factories is 38.42 tons (-0.62), the inventory of flake caustic soda factories is 2.30 tons (-0.28), and the operation rate of caustic soda is 80.50% (-2.00%) [2] - Downstream operation of caustic soda: The operation rate of alumina is 81.56% (+0.89%), the operation rate of printing and dyeing in East China is 60.25% (-0.13%), and the operation rate of viscose staple fiber is 75.17% (-3.40%) [2] Market Analysis PVC - Supply side: In July, upstream devices are under centralized maintenance, but the overall operation rate is expected to decline slightly due to chlor - alkali profit support. New production capacities are expected to be put into operation, so the supply pressure remains [3] - Demand side: It is the off - season for domestic downstream demand, and the operation rate of downstream products is at a low level. The domestic demand is weak, and the export orders are decreasing. Uncertain anti - dumping policies may affect exports [3] - Cost side: The calcium carbide market is expected to be weak, and the cost support for PVC's calcium carbide method is weak. The cancellation of the US export restriction on ethane to China may reduce the cost of PVC's ethylene method later [3] Caustic Soda - The sharp decline in Shandong's liquid chlorine price increases the marginal cost of caustic soda, suppressing the comprehensive profit of chlor - alkali. The weak demand and increasing supply of liquid chlorine may lead to further price drops and potential passive production cuts of caustic soda [3] - A Shandong alumina factory has raised the purchase price of liquid caustic soda, and downstream low - price restocking supports a slight rebound in the near - term spot price, but the overall demand improvement is limited [3] - Supply side: The operation rate of caustic soda is decreasing due to device maintenance, but new production capacities are expected to be put into operation, increasing supply pressure [3] - Demand side: The operation rate of the main downstream alumina is rising steadily, while the non - aluminum downstream demand is still weak [3] Strategy - PVC: After the macro - sentiment eases, PVC's trend returns to the fundamentals. It is expected to continue weak and volatile in the short term. With the inventory expected to accumulate, a short - selling strategy on rallies is recommended, and attention should be paid to macro - export policies and downstream demand recovery [4] - Caustic Soda: There is still room for the comprehensive profit of chlor - alkali to be compressed, the inventory reduction is difficult, and the fundamentals lack positive drivers. The upward space is limited, and attention should be paid to the price trend of liquid chlorine [4]

1. Report Industry Investment Rating - PVC: Neutral [4] - Caustic Soda: Neutral [4] 2. Core Viewpoints of the Report - After the macro - sentiment eases, PVC's trend returns to fundamentals. Its supply - demand pattern remains weak, and inventory is expected to continue accumulating. For caustic soda, the current chlor - alkali comprehensive profit still has room for compression, inventory removal is difficult, and the fundamentals lack positive drivers with limited upward momentum [3][4] 3.

Many enterprises have planned maintenance, but the chlor - alkali profit prevents significant production cuts. New production capacities such as Bohua, Yaowang, and Wanhua are expected to be put into operation, offsetting some of the maintenance losses. The supply side is under pressure [3] - Demand side: The operation rate of downstream products continues to decline, and domestic demand remains weak. Export orders are stable, and exports continue to increase. India's BIS standard policy is postponed for 6 months, supporting the short - term export market, but the anti - dumping policy is still uncertain [3] - Cost side: The calcium carbide market is weak due to more downstream maintenance, and the cost support for calcium carbide - based PVC is weak. The lifting of the US ban on ethane exports to China may reduce the cost of ethylene - based PVC later, but the impact is lagged [3] - Inventory: Due to sufficient supply and poor downstream demand, the social PVC inventory continues to accumulate [3] Caustic Soda - Supply side: The price of liquid chlorine drops significantly, increasing the marginal cost of caustic soda. There are concerns about potential passive production cuts. The operation rate of caustic soda decreases due to more maintenance, but the production cut intention is low. After maintenance, the operation rate is expected to rise, and new production capacities are planned to be put into operation, increasing supply pressure [3] - Demand side: The operation of the main downstream alumina is stable, with new production capacities expected in Shandong. The delivery volume of a Shandong alumina plant decreases, and the stocking enthusiasm declines. Non - aluminum downstream demand is weak [3] - Inventory and profit: The chlor - alkali comprehensive profit still has room for compression, inventory removal is difficult, and the fundamentals lack positive drivers [3] Strategy - PVC: Maintain a neutral stance. After the macro - sentiment eases, pay attention to macro - export policies and downstream demand recovery [4] - Caustic Soda: Maintain a neutral stance. With limited upward momentum, consider shorting on rallies [4]

Report Industry Investment Rating - PVC: Neutral [5] - Caustic Soda: Neutral [5] Core Viewpoints - The PVC price rebounded due to the market's expectation of supply - side regulation, but the weak supply - demand pattern remains, and the rebound may not last. The caustic soda futures price rose due to concerns about passive production cuts, but its fundamentals also lack positive drivers [4].
