1. Report Industry Investment Rating - Not provided in the document 2. Core Views of the Report - Alumina: The raw material end is affected by the rainy season in Guinea and mining area disturbances, with a potential decrease in bauxite shipments and rising prices. Domestic port inventories may decrease. Supply has a slight increase due to policy - related price increases and profit repair for smelters. Demand also shows a small increase as electrolytic aluminum production slightly rises. Overall, the fundamentals are in a stage of slightly increasing supply and demand, with cost support and improved supply expectations [4]. - Electrolytic Aluminum: The raw material cost is high with firm alumina prices and high - oscillating aluminum prices, resulting in good smelter profits and positive production willingness. Supply has a small increase due to previous technical renovation and capacity replacement projects, but production is approaching the industry ceiling. Demand is weak during the off - season, and high aluminum prices suppress downstream consumption. Short - term inventory may accumulate slightly, and the proportion of molten aluminum may decline [4]. - Cast Aluminum: High raw material costs squeeze smelter profits, and production may decrease due to cost - profit issues and the off - season. Demand is weak during the off - season, with cautious purchasing by consumers. Inventory is slightly accumulating [6]. - Strategy Suggestions: Trade the main contract of Shanghai aluminum lightly with a weak - oscillating view, and trade the main contract of alumina lightly by going long at low prices. Trade the main contract of cast aluminum lightly with an oscillating view. Pay attention to operation rhythm and risk control [4][6]. 3.
