1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports - Copper: The medium - to long - term fundamentals of copper remain good, with supply - side capital expenditure constraints supporting a gradual upward shift in the bottom. Short - term prices are likely to stay strong due to the structural imbalance of global inventories and the risk premium of metal supply concerns. However, real terminal demand is weak at high prices. Focus on changes in CL premium, LME inventory, and the 99000 - 100000 support level [1]. - Zinc: The shortage of zinc ore at the mine end supports prices, but the import window for zinc ore is opening, limiting the downside space of TC. The supply pressure of refined zinc is relieved, and demand is suppressed. Overseas and domestic inventories are increasing. Short - term prices are expected to fluctuate, with support from the tight domestic zinc ore supply and pressure from the expected supply of imported ore and weak demand feedback. Pay attention to zinc ore TC and refined zinc inventory changes, and the 23300 - 23400 support level [4]. - Nickel: The nickel market has seen significant price fluctuations. The unclear result of the 2026 nickel ore quota in Indonesia has affected market sentiment. High nickel prices have restricted downstream transactions, and the supply and demand situation is complex. Short - term prices are expected to adjust in a wide range, with the main contract running in the 132000 - 142000 range [6]. - Stainless Steel: The stainless - steel market is mainly driven by nickel raw materials. The unclear nickel ore quota in Indonesia has affected market expectations. The supply pressure has eased slightly, but demand in the off - season is weak. The cost support from the ore end and nickel - iron is strengthened. Short - term prices are expected to fluctuate, with the main contract in the 13400 - 14200 range [8]. - Lithium Carbonate: The lithium carbonate market has seen a significant increase in the price center last week. The supply - side shock expectation is strengthened, and demand is expected to be optimistic. The inventory situation has changed, with upstream inventory increasing and downstream inventory decreasing. The market is expected to maintain a strong and volatile trend, with a focus on the 150000 breakthrough and liquidity risks [10]. - Industrial Silicon: The industrial silicon market is expected to continue the pattern of weak supply and demand in January. Supply may decrease by 1 - 20,000 tons, and demand is expected to decline slightly. Exports may increase. The price is expected to fluctuate at a low level, mainly in the 8000 - 9000 yuan/ton range [11]. - Polysilicon: In January, the polysilicon market is in a weak - demand situation, with high inventory and price pressure. There is a need for further production cuts to balance supply and demand. Pay attention to the impact of antitrust news, the possibility of production cuts, and the redistribution of industrial chain profits. The 50000 yuan/ton level may provide support, and trading is recommended to wait and see [12]. - Tin: The short - term price of tin is greatly affected by macro - sentiment. The supply side may be affected by the situation in Congo (Kinshasa), and demand shows regional differences. The price is expected to fluctuate at a high level, and operations should be cautious [13]. - Alumina: The alumina market has been oscillating widely. The supply is rigid, and demand is weak, with inventory accumulating. The short - term price is expected to oscillate widely around the industry cash - cost line, with the main contract in the 2600 - 2950 yuan/ton range. A rebound depends on capacity - control policies or large - scale production cuts [14]. - Aluminum: The aluminum price has risen strongly, driven by macro and policy expectations. However, the fundamentals are under pressure, with supply increasing and demand being suppressed by high prices, and inventory starting to accumulate. Short - term prices are expected to oscillate widely at a high level, with the main contract in the 23000 - 25000 yuan/ton range [14]. - Aluminum Alloy: The casting aluminum - alloy market has shown a strong trend, mainly driven by cost factors. However, the supply and demand are both weak, with supply affected by raw - material shortages and demand being suppressed by high prices. Inventory has been gradually decreasing. Short - term prices are expected to oscillate in a high - level range, with the main contract in the 22000 - 24000 yuan/ton range [15]. 3.
