1. Report Industry Investment Rating - No information provided 2. Core Viewpoints - The main contract of caustic soda has changed to the 05 contract SH2605, which showed a volatile and slightly stronger trend, closing at 2,167 yuan/ton. Some chlor-alkali enterprises reduced their production loads during the Spring Festival due to low profits, leading to a decrease in caustic soda capacity utilization compared to before the festival. The downstream alumina开工率 maintained a slight downward trend due to maintenance in some enterprises. After the Spring Festival, chlor-alkali enterprises increased the price of liquid chlorine, and the prices of liquid chlorine in Shandong and Jiangsu rebounded, weakening the cost support for caustic soda. Some enterprises in Shandong raised their caustic soda quotes, and the market price increased compared to before the festival. Currently, there are still few plans for chlor-alkali plant maintenance. In the medium to long term, the continuous rebound of caustic soda spot prices requires future production cuts by enterprises. SH2605 is expected to show a volatile trend in the short term, with a daily range estimated to be around 2,130 - 2,230 yuan/ton [2] 3. Summary by Relevant Catalogs 3.1 Futures Market - The closing price of the main contract of caustic soda was 2,167 yuan/ton, a increase of 197 yuan; the position of the main contract was 140,547 lots, an increase of 88,864 lots; the net position of the top 20 futures was -20,345 lots, a decrease of 3,312 lots; the trading volume of the main contract was 242,102 lots, an increase of 85,242 lots. The closing prices of the January and May contracts were 2,378 yuan/ton and 2,167 yuan/ton, with an increase of 6 yuan and 14 yuan respectively [2] 3.2 Spot Market - The price of 32% ion-exchange membrane caustic soda in Shandong and Jiangsu regions was 629 yuan/ton and 720 yuan/ton respectively, with an increase of 11 yuan and no change. The converted price of 32% caustic soda in Shandong region was 1,966 yuan/ton, an increase of 35 yuan. The basis was -201 yuan/ton, a decrease of 162 yuan [2] 3.3 Upstream Situation - The mainstream prices of raw salt in Shandong and Northwest regions were 237.5 yuan/ton and 220 yuan/ton respectively, with no change. The price of steam coal was 645 yuan/ton, an increase of 1 yuan [2] 3.4 Industry Situation - The mainstream prices of liquid chlorine in Shandong and Jiangsu regions were -100 yuan/ton and 75.5 yuan/ton respectively, with no change and an increase of 125.5 yuan.

1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - Due to active replenishment by non-aluminum downstream last week, liquid caustic soda plant inventories were seasonally reduced, but inventory pressure remains high. Shandong chlor-alkali profits decreased month-on-month and entered a state of theoretical loss. Currently, there are still few maintenance plans for chlor-alkali plants, and there is no signal of production reduction in the industry, so the high operating rate is expected to continue in the short term. In February, some alumina enterprises will undergo maintenance due to factors such as environmental protection and flexible production, and the consumption of the alumina industry is expected to decline marginally. As the Spring Festival approaches, some non-aluminum downstream enterprises will gradually take holidays and stop work, leading to a seasonal decline in non-aluminum demand for caustic soda. Today, the price of liquid chlorine in Shandong turned negative, deepening the theoretical loss of Shandong chlor-alkali, and strengthening the cost support for caustic soda. With the game between weak supply and demand and cost support, caustic soda is expected to fluctuate in the short term. The daily range of SH2603 is expected to be around 1900 - 2000, and the daily range of SH2605 is expected to be around 2120 - 2200 [3] 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report Urea - In January, urea supply increased steadily, demand was strong due to pre - holiday stocking, and prices rose. In February, supply is expected to further increase, and demand will first decline and then recover after the Spring Festival. From March to May, urea prices are usually demand - driven, with strong support, but price increases may trigger price - stabilizing mechanisms [5][6][8]. Soda Ash - In January, soda ash supply increased, demand was weakly stable, and enterprise inventory slightly accumulated. In February, supply will continue to increase, and demand will shrink. The supply - demand situation will be looser, and inventory pressure will increase. However, external factors may have a positive impact on futures prices [11][12][13]. Glass - In January, glass supply decreased slightly, and demand was supported. In February, supply is expected to decline slightly, but demand will decline seasonally more than supply, and inventory pressure will remain high. In the long - term, the supply - demand contradiction is still not effectively resolved, but external factors may lead to short - term fluctuations [15]. 3.
