Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Viewpoints - **Alumina**: The alumina market is in a relatively stable supply - demand stage. The Guinea rainy season affects bauxite shipping, but domestic alumina production remains stable. With stable electrolytic aluminum capacity and increased inquiries from aluminum plants, the spot market transactions are improving. It is recommended to go long on dips with a light position [2]. - **Electrolytic Aluminum**: The electrolytic aluminum market may be in a stage of stable supply and increasing demand. Stable alumina supply, falling alumina prices, and expected interest rate cuts support aluminum prices. The production profit of smelters is good, and downstream orders are improving.
