Report Summary 1. Industry Investment Rating No information regarding the industry investment rating is provided in the report. 2. Core Viewpoints - PVC is expected to experience range - bound and weak oscillations. Supply is abundant due to the resumption of maintenance and new production capacity, while demand shows only a slight improvement in downstream开工率 with average purchasing sentiment. Exports are facing challenges such as the expected anti - dumping tax in India and weakening order volume. Inventory levels are high, and futures prices are under pressure [3]. - The spot price of caustic soda remains stable with a slight increase in the price of 50% caustic soda. Supply is increasing with the resumption of production in some plants, and demand from the alumina industry is affected by environmental control, while non - aluminum demand is expected to weaken. However, the potential commissioning of alumina plants in Guangxi may support the price in the next two months [3]. 3.
