Report Industry Investment Ratings - Copper: Not clearly defined in a standard form [1] - Aluminum: ★☆☆ (indicating a bias towards a certain trend but with limited trading operability) [1] - Alumina: Not clearly defined in a standard form [1] - Cast Aluminum Alloy: ★☆☆ [1] - Zinc: Not clearly defined in a standard form [1] - Nickel and Stainless Steel: ☆☆☆ (suggesting a relatively balanced short - term trend and poor operability) [1] - Tin: Not clearly defined in a standard form [1] - Lithium Carbonate: Not clearly defined in a standard form [1] - Industrial Silicon: Not clearly defined in a standard form [1] - Polysilicon: ☆☆☆ [1] Core Views - The overall performance of non - ferrous metals is affected by multiple factors such as geopolitical risks, dollar trends, inventory levels, and downstream demand. Different metals show different trends and investment outlooks [2][3][4] Summary by Metal Categories Copper - On Tuesday, copper prices fluctuated downward. High inventories may cause prices to test long - term moving average support [2] Aluminum & Alumina & Aluminum Alloy - Shanghai aluminum prices rose first and then fell. Short - term aluminum prices are expected to be volatile and slightly stronger. Cast aluminum alloy follows the trend of Shanghai aluminum, and the price difference may widen. The over - supply situation of alumina has improved, but the fundamental driving force is limited [3] Zinc - The zinc market lacks short - term long - position strength. High zinc prices suppress downstream purchasing enthusiasm. The supply - side pressure of domestic zinc ingots still exists, and the overall rebound is under pressure [4] Nickel and Stainless Steel - Shanghai nickel prices fluctuated and declined. The market is driven by policy sentiment in the short term, and the nickel market lacks independent driving force and gradually weakens [7] Tin - Shanghai tin prices decreased significantly with large two - way price fluctuations. The supply is expected to be stable in Q1, and the consumption outlook is weak [8] Lithium Carbonate - Lithium carbonate prices hit the daily limit down. The overall inventory reduction speed slows down, and the futures price rebound has high uncertainty [9] Industrial Silicon - Industrial silicon futures maintain a weak trend. The supply increases while the demand is weak, and there is an expectation of inventory accumulation in March [10] Polysilicon - Polysilicon futures continue to decline. There is an expectation of inventory reduction, but the market sentiment is weak, and the short - term price may remain weak [11]
