1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - The macro - sentiment has declined, and the spot price of near - term caustic soda has collapsed. The upside space of caustic soda is limited, with pressure at the 2800 price level. The supply of liquid caustic soda is expected to remain high, the overall demand is weak, and both liquid and flake caustic soda have seen a week - on - week inventory build - up. The caustic soda price has been falling this week, mainly due to weakening demand in the Shandong region and a downward adjustment in the purchase price of alumina, the main downstream product [3][6]. - For different market participants, corresponding hedging strategies are recommended. For example, producers with high inventory can buy put options and sell call options; traders looking to build inventory can sell put options and buy call options; terminal customers worried about price increases can buy call options [4]. 3.
