铝类市场周报：供需暂稳库存小增，铝类或将震荡运行-20251114

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - For alumina, the supply may slightly converge while the demand remains relatively stable. It is recommended to lightly go long on the alumina main contract at low prices, paying attention to operation rhythm and risk control [5]. - For electrolytic aluminum, the fundamentals may be in a stage of temporary supply - demand stability with a slight increase in social inventory. It is suggested to lightly trade the Shanghai Aluminum main contract in a volatile manner, paying attention to operation rhythm and risk control [5]. - For cast aluminum alloy, the fundamentals may be in a stage of converging supply and slightly decreasing demand. It is recommended to lightly trade the cast aluminum main contract in a volatile manner, paying attention to operation rhythm and risk control [6]. - In the options market, considering the subsequent aluminum price to fluctuate with potential volatility convergence, a double - selling strategy can be considered to short the volatility [74]. 3. Summary According to Relevant Catalogs 3.1 Week - ly Key Points Summary - Market Review: Shanghai Aluminum fluctuated, rising first and then falling, with a weekly increase of 0.99% to 21,840 yuan/ton. Alumina rebounded slightly, with a weekly increase of 1.4% to 2,822 yuan/ton. Cast aluminum main contract rose and then fell, with a weekly increase of 0.4% to 21,095 yuan/ton [5][6]. - Market Outlook: - Alumina: The supply tension of bauxite may ease. The current high - running capacity and high - level operation of alumina may affect smelter profits, leading to some high - cost enterprises reducing production. The demand from electrolytic aluminum remains relatively stable. The supply - demand situation may improve with production control [5]. - Electrolytic Aluminum: The raw material price rebounds slightly but remains low, and the smelter profit is good with high - level operation of capacity and high start - up rate. The domestic supply may remain high. The demand may slow down due to the transition of downstream consumption from peak to off - peak season and high aluminum prices, but the export demand may be boosted by overseas supply disturbances, resulting in only a slight increase in domestic inventory [5]. - Cast Aluminum Alloy: The supply of domestic scrap aluminum remains tight, and the cost support is strong. The production of cast aluminum enterprises is limited, and the demand may be affected by high prices and the transition from peak to off - peak season [6]. 3.2 Futures and Spot Market - Futures Price Movement: - As of November 14, 2025, Shanghai Aluminum closed at 21,750 yuan/ton, up 200 yuan/ton (0.93%) from November 7.
