1. Report Industry Investment Rating - Copper: Oscillating [7] - Alumina: Oscillating weakly [8] - Aluminum: Oscillating [10] - Aluminum alloy: Oscillating [13] - Zinc: Oscillating weakly [16] - Lead: Oscillating [17] - Nickel: Oscillating strongly in the short - term, waiting - and - seeing in the long - term [23] - Stainless steel: Oscillating in the short - term [24] - Tin: Oscillating [25] 2. Report's Core View - Overall non - ferrous metals: Weak US dollar and the fermentation of reverse invoicing issues are driving up the prices of basic metals. In the medium and short - term, prices are supported but the weak terminal demand limits the upside. In the long - term, potential domestic stimulus policies and supply disruptions support prices [1]. - Copper: Macro factors and supply disruptions support prices, and low inventory also provides support, but the US copper tariff is a negative factor [7]. - Alumina: The fundamentals are weak, with strong inventory accumulation trends, but short - term supply fluctuations and long - term mine disturbances need attention [9]. - Aluminum: Short - term macro sentiment is volatile, and the fundamentals are neutral. The aluminum price is expected to oscillate, and inventory and consumption need to be observed [12]. - Aluminum alloy: The cost is supported, supply is reduced, demand is rigid, and there are opportunities for cross - variety arbitrage [13]. - Zinc: The fundamentals are in surplus, and prices may oscillate weakly in the long - term [16]. - Lead: Supply and demand are basically balanced this week, but the release of smelter inventory after the events may pressure prices, and the price is expected to oscillate [19]. - Nickel: The market expects Indonesia's RKAB approval soon, so the price is oscillating strongly in the short - term, and the industry needs to observe the raw material and macro factors [23]. - Stainless steel: The price is expected to oscillate in the short - term, and the implementation of the peak season and inventory changes need attention [24]. - Tin: The supply is tight, providing a strong bottom support, but the terminal demand is weakening, so the price is expected to oscillate [25]. 3. Summary According to Relevant Catalogs 3.1 Copper - Information analysis: The Fed may cut interest rates, US GDP growth is better than expected, copper production has decreased, the spot premium has declined, and inventory has increased [7]. - Main logic: Macro factors and supply disruptions support copper prices, and low inventory also provides support, but the demand needs to be observed [7]. - Outlook: Copper may oscillate [8]. 3.2 Alumina - Information analysis: Spot prices have declined, some enterprises have reduced production due to environmental protection, and warehouse receipts have increased [8]. - Main logic: The fundamentals are weak, with strong inventory accumulation trends, but short - term supply fluctuations and long - term mine disturbances need attention [9]. - Outlook: Oscillating weakly, with opportunities for short - selling and reverse arbitrage [11]. 3.3 Aluminum - Information analysis: The price and inventory of aluminum have changed, an Indonesian enterprise is expected to be put into production, and the performance of related listed companies has been released [10]. - Main logic: Short - term macro sentiment is volatile, and the fundamentals are neutral. The aluminum price is expected to oscillate, and inventory and consumption need to be observed [12]. - Outlook: The aluminum price is expected to oscillate in the short - term [12]. 3.4 Aluminum Alloy - Information analysis: The price and spread of aluminum alloy have changed, the exchange has adjusted margins and price limits, and the performance of related listed companies has been released [13]. - Main logic: The cost is supported, supply is reduced, demand is rigid, and there are opportunities for cross - variety arbitrage [13]. - Outlook: Short - term prices are oscillating at a low level, and there is room for recovery and cross - variety arbitrage opportunities [15]. 3.5 Zinc - Information analysis: The spot discount and inventory of zinc have increased, and a smelter will conduct maintenance [15]. - Main logic: The fundamentals are in surplus, and prices may oscillate weakly in the long - term [16]. - Outlook: Zinc prices may oscillate weakly in the long - term [16]. 3.6 Lead - Information analysis: The price, spread, and inventory of lead have changed, and the market transaction is light [16]. - Main logic: Supply and demand are basically balanced this week, but the release of smelter inventory after the events may pressure prices, and the price is expected to oscillate [19]. - Outlook: The lead price is expected to oscillate [19]. 3.7 Nickel - Information analysis: The inventory of nickel has increased, and there are many industry news items [19]. - Main logic: The market sentiment dominates the price, the industry fundamentals are weakening marginally, and short - term trading is recommended [23]. - Outlook: The nickel price is oscillating strongly in the short - term, and waiting - and - seeing in the long - term [23]. 3.8 Stainless Steel - Information analysis: The inventory of stainless steel warehouse receipts has increased, and the production in Indonesia is normal [24]. - Main logic: The prices of nickel - iron and chromium - iron have changed, production has increased, and inventory has decreased slightly. The price is expected to oscillate in the short - term [24]. - Outlook: The stainless steel price is expected to oscillate in the short - term [24]. 3.9 Tin - Information analysis: The inventory and price of tin have changed, and a company will conduct maintenance [25]. - Main logic: The supply is tight, providing a strong bottom support, but the terminal demand is weakening, so the price is expected to oscillate [25]. - Outlook: The tin price is expected to oscillate, and the volatility may increase [25].
