Report Industry Investment Rating No relevant content provided. Core Views Caustic Soda - In the short term, the supply of caustic soda is at a high level, the price of downstream alumina continues to weaken, industry profits are shrinking, and demand - side support is weak, resulting in insufficient support for market prices. In the medium term, as the demand procurement cycle approaches and downstream has restocking needs, caustic soda prices are expected to be supported. Considering the production schedule, there will be more alumina production in Q1 2026, so there may be concentrated stockpiling in Q4 2025, which may tighten spot liquidity. For non - aluminum sectors, after the National Day, as the previous non - aluminum inventory decreases, there may be purchasing willingness due to low prices. It is recommended to stop profiting on existing short positions and track downstream restocking rhythms [2]. PVC - This week, the PVC futures market stopped falling and stabilized, showing a volatile trend. On the supply side, there were still many maintenance enterprises this week, resulting in low production loads. However, it is expected that some maintenance enterprises will end maintenance next week, increasing production and bringing supply back to a high level. On the demand side, domestic downstream construction remains low, product orders are limited, and downstream continues to purchase on a need - to - basis at low prices. The cost of raw material calcium carbide has been rising, but the increase is limited, and the ethylene price may be lowered next week. The cost side provides bottom - level support. In the future, the logic of a lackluster peak season is expected to continue, the futures market will still face pressure, but the absolute price is already low, and a short - term operation strategy of shorting on rebounds is recommended [3]. Summary by Directory Caustic Soda Price and Market Trends - The caustic soda futures price has shown significant fluctuations due to various factors such as macro - economic conditions, alumina price changes, and cost movements. For example, factors like the relaxation of Sino - US tariff conflicts, the strengthening of alumina profits, and the expectation of alumina production resumption have affected the spot - buying willingness and futures prices [6]. Supply - The weekly weighted average operating load rate of sample enterprises in major regions across the country was 85.55%, a 0.1 - percentage - point increase from last week. The caustic soda production in terms of 100% purity was 82.53 tons, a 0.12% increase from last week. Although there were many chlor - alkali device maintenance activities, some enterprises with previously low loads increased their production. Multiple enterprises across different regions are in maintenance or have planned maintenance, with a total weekly maintenance loss of 6.92 tons [25][26]. Demand - Alumina is a major downstream consumer of caustic soda. From late 2025 to 2026, the planned alumina production capacity is 12.3 million tons (including 2 million tons of replacement), with an estimated annual production capacity growth rate of around 10%. The estimated alumina annual output in 2026 will exceed 88 million tons, with a production growth rate of around 6%. The new alumina projects are expected to increase the demand for caustic soda by about 800,000 tons per year, with a relatively concentrated demand increase of 150,000 tons from April to June. In addition, the non - aluminum downstream sectors, such as the printing and dyeing industry, have a seasonal increase in the operating rate, while the viscose staple fiber industry has a decline in the operating rate [30][50]. Export - In September 2025, the export profit of caustic soda increased, and the export volume rebounded significantly. However, the estimated export profit declined in October [54]. PVC Price and Market Trends - The PVC futures price has fluctuated due to factors such as supply - demand relationships, macro - economic sentiment, and cost changes. The spot price has been weakening [61][62]. Supply - This week, the overall operating load rate of PVC powder was 73.74%, a 1.4 - percentage - point decrease from last week. Among them, the operating load rate of calcium - carbide - based PVC powder was 71.65%, a 3.08 - percentage - point decrease, and the operating load rate of ethylene - based PVC powder was 78.56%, a 2.46 - percentage - point increase. Many enterprises are in long - term, current, or planned maintenance, which affects the supply of PVC [83][85]. Demand - The two major downstream sectors of PVC, profiles and pipes, are facing pressure from both demand and industry competition, and the industry's contribution is difficult to improve. The real - estate sector, with the goal of "reducing inventory and stabilizing prices," continues to have a negative impact on demand. According to sample data, downstream orders are significantly lower than the average of the past five years, and both raw material and finished - product inventories are at high levels [93]. Inventory - PVC inventory has been continuously increasing, and the total inventory is at the highest level in recent years compared to the same period [101]. Export and Import - In September 2025, the PVC import volume was 14,400 tons, with an average import price of $736 per ton, and the cumulative import from January to September was 175,500 tons. The single - month import volume increased by 16.08% month - on - month and 7.73% year - on - year, with a cumulative year - on - year increase of 0.76%. The export volume in September was 346,400 tons, with an average export price of $612 per ton, and the cumulative export from January to September was 2.9216 million tons. The single - month export volume increased by 21.945% month - on - month and 24.53% year - on - year, with a cumulative year - on - year increase of 50.63% [119].

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - PVC is in a state of high production and weak demand, with an expected increase in inventory in the future. The fundamentals are difficult to improve, but the valuation is at a relatively low level, and there may be positive macro - level news, so it is expected to show a short - term oscillatory trend. Technically, V2601 should pay attention to the support around the previous low of 4644 and the pressure around the 20 - day moving average of 4812 [3]. 3. Summary by Relevant Catalogs a.

The implied volatility of at - the - money put options and call options is 15.05%, with the put option up 0.01 percentage points and the call option unchanged [3]. b. Industry News - From October 11th to 17th, the capacity utilization rate of Chinese PVC was 76.69%, a significant decline compared to the previous period. The downstream operating rate of PVC increased by 9.38% to 48.59%, with the pipe operating rate increasing by 7.17% to 40% and the profile operating rate increasing by 17.39% to 33.26% [3]. - As of October 16th, the social inventory of PVC decreased by 0.24% to 1.0338 million tons compared to the previous week. The average cost of calcium carbide - based PVC increased to 5142 yuan/ton, and the national average cost of ethylene - based PVC decreased to 5432 yuan/ton. The profit of calcium carbide - based PVC decreased to - 731 yuan/ton, and the profit of ethylene - based PVC decreased to - 552 yuan/ton [3]. c. Outlook - This week, many PVC plants are expected to restart, and the impact of newly shut - down plants is limited, so the capacity utilization rate of PVC is expected to return to a high level. In October, there are few maintenance plants and new production capacity is increasing, resulting in relatively high supply pressure [3]. - The real estate market remains weak, and downstream orders are poor. Downstream is expected to maintain just - in - time procurement. Affected by India's anti - dumping tax, the export market may remain on the sidelines. Due to the high - production and weak - demand situation of PVC, there is still an expectation of inventory accumulation in the future [3]. - The calcium carbide - based process is deeply in the red, and chlor - alkali enterprises use caustic soda profits to offset chlorine losses. However, the supply of calcium carbide is abundant and the price is weak, so the cost - side support is limited [3].

Report Industry Investment Rating - No investment rating is provided in the report. Core Viewpoints - The PVC market is under significant pressure due to high social inventory, upcoming end of equipment maintenance, average spot trading, and high futures warehouse receipts. However, the recent major conference may affect macro - sentiment, and the cost side of PVC has strengthened. It is recommended to exit and wait and see [1]. Summary by Related Catalogs Market Analysis - The calcium carbide price in the upstream northwest region is stable. The PVC operating rate decreased by 5.94 percentage points to 76.69% on a month - on - month basis, still at a relatively high level in recent years. After the National Day, the downstream recovery of PVC was significant, but it is still at a relatively low level in the same period over the years. India postponed the BIS policy for another six months until December 24, 2025. Formosa Plastics in Taiwan, China, lowered its November quotation by $30 - 40 per ton. India increased the anti - dumping duty on imported PVC from the Chinese mainland by about $50 per ton on August 14, weakening the export expectation of Chinese PVC in the fourth quarter. However, after the recent decline in export prices, export orders have not weakened significantly. The real estate is still in the adjustment stage, and it will take time to improve [1]. Futures and Spot Market - The PVC2601 contract decreased in positions and fluctuated. The lowest price was 4,670 yuan per ton, the highest was 4,725 yuan per ton, and it finally closed at 4,699 yuan per ton, below the 20 - day moving average, with a decline of 0.47%. The position volume decreased by 14,260 lots to 1,191,906 lots [2]. - On October 21, the mainstream price of calcium carbide - based PVC in East China dropped to 4,625 yuan per ton. The futures closing price of the V2601 contract was 4,699 yuan per ton. The current basis was - 74 yuan per ton, weakening by 16 yuan per ton, and the basis was at a relatively low - neutral level [3][4]. Fundamental Tracking - Supply side: Some devices such as Shandong Xinfa, Lutai Chemical, and Inner Mongolia Junzheng entered maintenance. The PVC operating rate decreased by 5.94 percentage points to 76.69% on a month - on - month basis. New production capacities have been put into operation, including Wanhua Chemical with an annual capacity of 500,000 tons in August, Tianjin Bohua with an annual capacity of 400,000 tons expected to be in stable production by the end of September, Qingdao Gulf with an annual capacity of 200,000 tons put into operation in early September and approaching full - load production, and Gansu Yaowang and Jiaxing Jiahua with annual capacities of 300,000 tons each running at low loads after trial production [5]. - Demand side: The real estate is still in the adjustment stage. From January to September 2025, the national real estate development investment was 677.06 billion yuan, a year - on - year decrease of 13.9%. The sales area of commercial housing was 658.35 million square meters, a year - on - year decrease of 5.5%. The sales volume of commercial housing was 630.4 billion yuan, a decrease of 7.9%. The new construction area of houses was 453.99 million square meters, a year - on - year decrease of 18.9%.
