1. Report Industry Investment Ratings No relevant information provided. 2. Core Views of the Reports Aluminum - The market surplus pressure of alumina remains severe, and its price is expected to fluctuate widely around the industry cash - cost line, with the main contract reference range of 2600 - 2950 yuan/ton. The key to a trend - like rebound lies in subsequent capacity control policies or large - scale substantial production cuts [1]. - The strong macro and policy expectations provide a solid bottom for aluminum prices, but the weakening supply - demand fundamentals and inventory accumulation pressure will significantly limit the upside space. Aluminum prices are expected to fluctuate widely at high levels in the short term, with the main contract of Shanghai Aluminum operating in the range of 23200 - 24400 yuan/ton [1]. Carbonate Lithium - The supply of carbonate lithium is expected to increase slightly, and downstream demand maintains a certain resilience. However, there is limited new driving force in essence. After the holiday, the news has significantly boosted the sentiment of the non - ferrous sector. The market is expected to fluctuate strongly, and attention should be paid to the breakthrough around 130,000 yuan [2]. Aluminum Alloy - The price of ADC12 is expected to continue to fluctuate in a high - level range in the short term, with the main contract reference range of 22400 - 23400 yuan/ton. Attention should be paid to raw material supply, import window changes, and the actual stocking rhythm of downstream enterprises before the Spring Festival [3]. Tin - The market sentiment has fluctuated greatly recently, causing tin prices to fluctuate sharply. It is advisable to operate with caution, and subsequent attention should be paid to the macro situation and the recovery of the supply side [5]. Industrial Silicon - In January, industrial silicon is expected to continue the pattern of weak supply and demand, and the futures price is under pressure. It is still expected that the price of industrial silicon will fluctuate at a low level, with the main price fluctuation range of 8000 - 9000 yuan/ton [7]. Polysilicon - The spot price of polysilicon has increased, and the futures price has risen and then fallen. In January, the demand is weak, and there is pressure for further production cuts to balance supply and demand. It is recommended to wait and see for the time being, and pay attention to the production cut situation and price adjustment acceptance [9]. Nickel - The recent expectation of Indonesia's increased control over nickel mines has boosted market sentiment, but the weak fundamentals still restrict the upside space of prices. The disk is expected to maintain a strong - side operation, with the main reference range of 130,000 - 138,000 yuan. Attention should be paid to the possibility of a callback after the impact of the news is digested [10]. Stainless Steel - The supply pressure of stainless steel has eased slightly, and the cost support of ore and ferronickel has been strengthened, but the demand in the off - season is still insufficient. The disk is expected to maintain a strong - side shock adjustment, with the main reference range of 12800 - 13500 yuan. Attention should be paid to the ore - end news and downstream stocking [11]. Zinc - Affected by the Venezuela event, zinc prices rose sharply. The supply of domestic zinc concentrates is tight, and the supply pressure of refined zinc has been relieved. The demand side is performing well. In the short term, the price will fluctuate strongly in a warm macro - environment, and attention should be paid to import profit and loss, TC inflection points, and refined zinc inventory changes [12]. Copper - The medium - and long - term fundamentals of copper are still good, but in the short term, the previous sharp rise in prices has suppressed real demand. Although the current price is over - valued to some extent, it may still maintain a strong trend in a high - risk - preference environment, with the main contract paying attention to the 95500 - 96000 support [13]. 3.
