1. Report Industry Investment Rating - No relevant content found 2. Core Viewpoints of the Report - Last week, Qilu Petrochemical's 360,000 - ton unit restarted, while LG Chemical's 400,000 - ton and Henan Lianchuang's 400,000 - ton units were under maintenance, leading to a decline in PVC capacity utilization rate. The start - up rate of pipes increased slightly, while that of profiles continued to decline, and the downstream start - up rate of PVC decreased slightly. Social inventory decreased slightly, but the inventory pressure remained high. The prices of raw materials such as calcium carbide, ethane, and vinyl chloride dropped, driving down the costs of calcium carbide and ethylene processes. Due to the weak spot price of PVC, the losses of both processes deepened. This week, LG Chemical's 400,000 - ton unit will restart, and the impact of previously restarted units will expand, so the PVC capacity utilization rate is expected to increase. In winter, it is the off - season for chlor - alkali plant maintenance, and PVC generally maintains a high - start state. As the temperature drops, the terminal demand of infrastructure and real estate weakens, and the downstream start - up rate of PVC is expected to decline seasonally. There is no specific implementation time for India's anti - dumping duty, and overseas demand remains uncertain. The domestic supply - demand contradiction is significant, and it is difficult to reduce PVC inventory, with high inventory pressure likely to continue. The price support of calcium carbide and ethylene at the cost end is limited. In the short term, V2601 is expected to fluctuate weakly in the range of 4,490 - 4,620 [2]. 3.

Report Industry Investment Rating No relevant content provided. Core Views - The caustic soda industry still faces certain supply - demand pressures. The purchasing enthusiasm of the main downstream alumina has declined, and the long - term supply - demand remains under pressure. The price is expected to fluctuate weakly. For PVC, the supply - demand is in an oversupply situation, and the price is hard to be optimistic, with an expected continuation of the bottom - weakening pattern. Futures strategies suggest a bearish approach, and option strategies suggest waiting and seeing [2][3][4][5]. Summary by Related Catalogs Caustic Soda - **Price and Market Situation**: The caustic soda futures price has shown various trends due to factors such as macro - environment, supply - demand changes, and cost fluctuations. The spot price has also been affected by factors like alumina demand and enterprise profit. For example, the Shandong liquid chlorine price going negative has impacted enterprise profits, and the price has support at the 2350 level [8]. - **Supply**: The national average weekly weighted operating load rate of sample enterprises was 89.79%, a decrease of 0.07 percentage points from last week. The caustic soda output in terms of 100% purity was 86.62 tons, a 0.08% decrease from last week. Some chlor - alkali plants reduced production due to maintenance or breakdowns. There are also many maintenance plans for caustic soda plants in different regions [27][28]. - **Demand**: Alumina is the main downstream of caustic soda. From the end of 2024 to 2025, there are plans to put into production 12.3 million tons of alumina capacity (including 2 million tons of replacement), with an estimated annual production increase of about 6%. The new alumina capacity is expected to increase the demand for caustic soda by about 800,000 tons per year. However, the alumina industry currently has poor profits, and the price is expected to be weak in the short - term, with a price range of 2750 - 2950 yuan/ton. Non - aluminum downstream industries such as printing, dyeing, and textiles also have weak demand [32][33][36]. - **Export**: In September, the export profit of caustic soda increased, and the export volume rebounded significantly. However, it is estimated that the export profit will decline later [57]. Polyvinyl Chloride (PVC) - **Price and Market Situation**: The PVC futures price has continued to decline due to the lack of positive supply - demand drivers and a poor commodity market atmosphere. The spot price has also been weak, with the core issue being the lack of substantial improvement in supply - demand [64][65]. - **Profit**: The industry profit of PVC has been deteriorating, including the profits of the calcium carbide method and ethylene method in the East China region, as well as the marginal integrated profit and northwest integrated profit [70]. - **Supply**: The domestic PVC powder industry's operating load rate decreased this week. There were 2 new planned maintenance devices, and the overall maintenance loss increased. The overall operating load rate of PVC powder was 76.71%, a decrease of 2.57 percentage points from last week. Among them, the operating load rate of calcium carbide - based PVC powder was 79.57%, a decrease of 0.6 percentage points, and that of ethylene - based PVC powder was 70.13%, a decrease of 7.1 percentage points [84]. - **Demand**: The two major downstream industries of PVC, profiles and pipes, face great pressure. The real estate industry, which is the main demand source, is still in the bottom - building period, and the demand is expected to continue to be negative. The domestic demand has not improved significantly, and the downstream orders are significantly lower than the average level of the past five years, with high raw material and finished - product inventories [96]. - **Inventory**: The PVC inventory has decreased slightly, but the total inventory is still at the highest level in recent years compared year - on - year [104]. - **Export**: In September 2025, the PVC import volume was 14,400 tons, with a month - on - month increase of 16.08% and a year - on - year increase of 7.73%. The export volume was 346,400 tons, with a month - on - month increase of 21.945% and a year - on - year increase of 24.53% [122].

Report Industry Investment Rating - The trend strength of caustic soda is -1, indicating a relatively bearish view [4] Core View of the Report - The high - production and high - inventory pattern of caustic soda continues, and the market keeps shorting the chlor - alkali profit [3] - The impact of alumina's production - start and production - cut expectations on caustic soda basically offsets each other, and the supply pressure in the domestic market increases [3] - The valuation of caustic soda is always suppressed by the alumina production - cut expectation, and the cost support is limited, making it difficult for caustic soda to rebound significantly [3] - In the long term, the alumina production - cut problem will lead to negative feedback in the industrial chain [3] Summary by Relevant Catalogs Fundamental Tracking - On November 18, 2025, the 01 - contract futures price was 2291, the price of the cheapest deliverable 32% caustic soda in Shandong was 760, the Shandong spot 32% caustic soda converted to the futures price was 2375, and the basis was 84 [1] Spot News - On November 17, due to poor unloading of alumina, the main downstream product in Shandong, the purchase price of 32% caustic soda was reduced by 10 yuan to 720 yuan, and the transaction prices in cities across Shandong followed the decline, with a relatively large drop in the southwestern Shandong market due to high inventory [2] Market Condition Analysis - The high - production and high - inventory situation of caustic soda persists, and the market is shorting chlor - alkali profit [3] - From the demand side, the impact of alumina's production - start and production - cut expectations on caustic soda offsets each other. In winter, there is limited supply - demand gap caused by stockpiling under high - operation conditions. Non - aluminum downstream support is limited, and exports are under pressure, increasing domestic supply pressure [3] - The valuation of caustic soda is suppressed by alumina production - cut expectations, cost support is limited, and without production cuts by manufacturers, it's hard for caustic soda to rebound significantly. In the long run, alumina production cuts will cause negative feedback in the industrial chain [3] Trend Strength - The trend strength of caustic soda is -1, with a range of [-2, 2], where -2 is the most bearish and 2 is the most bullish [4]
