Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Views - The fundamentals of electrolytic aluminum may be in a stage of stable supply and increasing demand. It is recommended to conduct short - term long positions on the main contract of Shanghai Aluminum at low prices with a light position, and conduct oscillatory trading on the main contract of alumina with a light position [5]. - The fundamentals of alumina are currently in a state of oversupply with a slight accumulation of inventory [6]. - The fundamentals of cast aluminum alloy may be in a stage of slightly reduced supply and slightly improved demand. It is recommended to conduct short - term long positions on the main contract of cast aluminum at low prices with a light position [8]. - Given that the aluminum price will be supported in the future, a double - buying strategy can be considered to bet on increased volatility [75]. 3. Summary by Catalog 3.1 Week - to - week Key Points Summary - Electrolytic Aluminum: The supply of raw material alumina is sufficient, and the smelting profit remains at a good level. The demand for downstream aluminum processing has increased due to the traditional consumption season and pre - holiday stockpiling [5]. - Alumina: The impact of the rainy season in Guinea on shipments continues, and the supply of domestic bauxite is expected to be tight. However, the overall supply is still sufficient, and the demand is slightly increased but less than the supply growth, with a slight accumulation of inventory [6]. - Cast Aluminum Alloy: The supply of raw material scrap aluminum is tight, limiting production. The pre - holiday stockpiling and the decline in cast aluminum quotes have slightly improved downstream demand, but consumption is still weak, and inventory has slightly increased [8]. 3.2 Futures and Spot Markets - Price Movement: As of September 19, 2025, the closing price of Shanghai Aluminum was 20,780 yuan/ton, down 2.37% from September 12; the closing price of LME Aluminum on September 18 was 2,705 US dollars/ton, up 0.97% from September 12.
