1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints - Domestic caustic soda supply and demand have improved, factory inventories at high levels are being reduced, and spot prices are supported. The easing signal from the Middle East geopolitical situation has led to a decline in the main caustic soda futures, causing a partial convergence of the basis. The improvement in caustic soda exports may depend on the duration of the Middle East geopolitical conflict and the closure of the Strait of Hormuz. In the short term, the price of SH2605 is still dominated by Middle East geopolitical news and should be treated with volatility [3] 3.

1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - The short - term SH2605 is expected to fluctuate weakly, and attention should be paid to the pressure around 2180 technically. The industry's capacity utilization rate is expected to rise to a high level, the demand for caustic soda may increase, but the inventory removal is still difficult and the pressure is high. The rising price of liquid chlorine may weaken the cost support of caustic soda [3][4] 3.

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Short - term SH2603 is expected to show a fluctuating trend, with attention on the support around 2090 and the resistance around 2260 [3][4] - The spot supply and demand of liquid caustic soda remain generally loose, and the purchase and market prices of the 32% liquid caustic soda main product in Shandong have declined recently [3] - The planned maintenance capacity of chlor - alkali in January is small, and the previously shut - down devices are restarting one after another. Domestic chlor - alkali devices are expected to maintain a high - operation state [3] - The operating load of alumina enterprises will basically remain stable in the short term, and non - aluminum downstream may maintain rigid procurement with little change [3] - Although the profit of Shandong chlor - alkali has narrowed due to the decline in caustic soda prices, it is still in a theoretical profit state [3] 3. Summary by Relevant Catalogs 3.1 Futures Market - The closing price of the main caustic soda contract is 2194 yuan/ton, and the position volume of the main caustic soda contract is 159,963 hands, with a decrease of 15,593 hands [3] - The net position of the top 20 in futures is - 14,547 hands, and the trading volume of the main caustic soda contract is 344,227 hands, with an increase of 30,386 hands [3] - The closing price of the January caustic soda contract is 1970 yuan/ton, and the closing price of the May caustic soda contract is 2330 yuan/ton, with an increase of 27 [3] 3.2 Spot Market - The price of 32% ion - membrane caustic soda in Shandong is 690 yuan/ton, and in Jiangsu is 780 yuan/ton [3] - The converted - to - 100% price of 32% caustic soda in Shandong is 2156.25 yuan/ton, and the basis is - 38 yuan/ton, with a decrease of 30 [3] 3.3 Upstream Situation - The mainstream price of raw salt in Shandong is 250 yuan/ton, and in the Northwest is 220 yuan/ton [3] - The price of steam coal is 642 yuan/ton [3] 3.4 Industry Situation - The mainstream price of liquid chlorine in Shandong is 250 yuan/ton, and in Jiangsu is 225 yuan/ton, with a decrease of 25 [3] 3.5 Downstream Situation - The spot price of viscose staple fiber is 12,900 yuan/ton, and the spot price of alumina is 2600 yuan/ton, with a decrease of 10 [3] 3.6 Industry News - From December 27 to January 2, China's caustic soda capacity utilization rate was 86.4%, a week - on - week increase of 0.4% [3] - From December 27 to January 2, the alumina operating rate decreased by 0.47% week - on - week to 84.67%, the viscose staple fiber operating rate decreased by 1.61% week - on - week to 85.42%, and the printing and dyeing operating rate decreased by 0.47% week - on - week to 60.81% [3] - As of January 2, the inventory of liquid caustic soda factories was 485,700 tons (wet tons), a week - on - week increase of 9.84% [3] - From December 25 to January 4, the weekly average profit of Shandong chlor - alkali was 153 yuan/ton, a decrease compared with the previous period [3]

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Last week, the inventory of liquid caustic soda factories accumulated significantly. Affected by the decline in caustic soda prices, the profits of Shandong chlor - alkali enterprises decreased month - on - month and maintained a contraction trend. This week, some facilities in East and North China will restart, and the newly followed - up maintenance capacity is scarce. The utilization rate of caustic soda production capacity is expected to increase month - on - month. In December, caustic soda is generally expected to be in a situation of relatively high supply. Alumina enterprises have no news of production cuts, and their procurement demand is low under the background of low profits; non - aluminum downstream may maintain rigid procurement with little change. The inventory is expected to remain at a high level, the supply will continue to be loose, the spot price will be under pressure, and it is more likely that the spot price will decline to narrow the basis in the future. SH2601 is expected to fluctuate weakly, but the high basis and low corresponding profit level may limit the decline space, with the daily range expected to be around 2180 - 2250 [2]. 3. Summary by Directory 3.1 Futures Market - The closing price of the main caustic soda contract was 2212 yuan/ton, a decrease of 12 yuan/ton; the position of the main caustic soda contract was 148,447 lots, a decrease of 8006 lots; the net position of the top 20 futures was 5467 lots; the trading volume of the main caustic soda contract was 275,167 lots, an increase of 69,841 lots; the closing price of the January caustic soda contract was 2212 yuan/ton, a decrease of 12 yuan/ton; the closing price of the May caustic soda contract was 2390 yuan/ton, an increase of 2 yuan/ton; the net position of the top 20 futures was - 18,551 lots [2]. 3.2 Spot Market - The price of 32% ion - membrane caustic soda in Shandong was 730 yuan/ton, a decrease of 20 yuan/ton; in Jiangsu, it was 880 yuan/ton, unchanged; the converted - to - 100% price of 32% caustic soda in Shandong was 2281 yuan/ton, a decrease of 63 yuan/ton; the basis of caustic soda was 69 yuan/ton, a decrease of 51 yuan/ton [2]. 3.3 Upstream Situation - The mainstream price of raw salt in Shandong was 222.5 yuan/ton, unchanged; in the Northwest, it was 220 yuan/ton, unchanged; the price of steam coal was 654 yuan/ton, a decrease of 1 yuan/ton [2]. 3.4 Industry Situation - The mainstream price of liquid chlorine in Shandong was 50.5 yuan/ton, unchanged; in Jiangsu, it was 150 yuan/ton, unchanged [2]. 3.5 Downstream Situation - The spot price of viscose staple fiber was 13,060 yuan/ton, unchanged; the spot price of alumina was 2770 yuan/ton, unchanged. From November 21st to 27th, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons and above was 85.0%, a month - on - month increase of 0.4%. From November 22nd to 28th, the alumina operating rate increased by 0.60% month - on - month to 86.06%, the viscose staple fiber operating rate increased by 1.20% month - on - month to 91.29%, and the printing and dyeing operating rate decreased by 1.02% month - on - month to 65.53%. As of November 27th, the factory inventory of fixed liquid caustic soda sample enterprises nationwide was 469,800 tons (wet tons), a month - on - month increase of 9.89% and a year - on - year increase of 87.95%. From November 21st to 27th, the average weekly profit of Shandong chlor - alkali enterprises was 357 yuan/ton, a decrease from the previous week [2].

Group 1: Core Viewpoints - Last week, the subsidy for liquid chlorine in Shandong was alleviated, but due to the significant decline in caustic soda prices, the profit of chlor-alkali in Shandong contracted on a month-on-month basis. The chlor-alkali maintenance plan in September was basically fulfilled. This week, multiple sets of equipment such as Xinpu Chemical, Gansu Jinchuan, and Heilongjiang Haohua will restart, which is expected to drive the capacity utilization rate of caustic soda to rise month-on-month [3]. - The profit of alumina continued to shrink. Although enterprises have not yet experienced cost-driven production cuts, their purchasing intention has significantly weakened. The terminal demand in the traditional peak season is average, and non-aluminum downstream is resistant to high prices. Considering the relatively loose supply of liquid caustic soda during the pre-National Day replenishment period for downstream, the spot price of liquid caustic soda in Shandong is expected to remain under pressure [3]. - In the futures market, the recent market sentiment has declined, and the sharp decline in the futures price has led to the convergence of the basis. From the fourth quarter to early next year, the commissioning of new alumina plants will still support the demand. Attention should be paid to the subsequent stocking rhythm. Technically, SH2601 should focus on the support of the lower Bollinger Band around 2500 [3]. Group 2: Market Data Summary Futures Market - The closing price of the main caustic soda contract was 2548 yuan/ton, with a month-on-month increase of 13 yuan/ton.

1. Report Industry Investment Rating - Not provided 2. Core View of the Report - SH2601 fluctuated strongly and closed at 2,571 yuan/ton. Last week, the average national caustic soda capacity utilization rate decreased by 0.8% to 83.4%. In terms of demand, the alumina开工率 increased by 0.83% to 85.21%, the viscose staple fiber开工率 increased by 0.67% to 87.77%, and the printing and dyeing开工率 increased by 0.13% to 65.76%. The inventory of national liquid caustic soda factories decreased by 7.99% to 356,800 tons last week, resuming the destocking trend. There are planned maintenance devices in the northwest and northeast this week, and the capacity utilization rate is expected to decline month - on - month. There are many maintenance plans for chlor - alkali devices in September, and the industry supply pressure is expected to be relieved. Alumina enterprises' profits are shrinking but there is no cost - based production cut, and the amount of caustic soda delivered is still high. Non - aluminum downstream in Shandong shows resistance to high prices, and the market price of liquid caustic soda has declined. The inventory pressure is not large, and the supply of goods in South and Southwest China is currently tight. Benefiting from the upcoming introduction of a new round of policies to stabilize growth in key industries, industrial products rose mainly on the day. Technically, SH2601 should pay attention to the support near 2,530 and the pressure near 2,630 [3] 3.
