Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. 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 units 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 on a month - on - month basis [3]. - The profit of alumina continued to shrink. Although enterprises have not yet cut production due to cost, their purchasing intention has weakened significantly. 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][4]. - In the futures market, there are still expectations for anti - involution and restocking of new alumina plants. There is a game between weak reality and strong expectations. SH2601 is expected to fluctuate widely, and the main basis may remain negative. Attention should be paid to the restocking rhythm of new alumina production capacity in the future. The short - term operating range of SH2601 is expected to be around 2580 - 2680 [3][4]. 3.
