1. Report Industry Investment Ratings No information about the report industry investment ratings is provided in the content. 2. Core Views of the Report Zinc - Overseas monetary policy tightening expectations put pressure on market risk appetite, and spot trading improvement is limited. Zinc prices oscillated and adjusted. The shortage of zinc ore supports prices, but the high zinc prices suppress demand. The overall fundamentals are good, and the downside space of zinc prices may be limited. Pay attention to the changes in zinc ore TC and refined zinc inventory [2]. Copper - The expectation of copper storage at home and abroad is strengthened, and copper prices stabilized and rebounded. The short - term supply of copper ore is tight, and the demand has recovered. The medium - and long - term logic remains unchanged, and the bottom center of copper prices is expected to rise gradually. In the short term, with the narrowing of CL premium, copper prices may return to fundamental pricing [5]. Tin - The short - term tin prices are easily affected by market sentiment and may fluctuate sharply. In the medium and long term, although the supply side is gradually recovering, considering the low elasticity of supply and the long - term narrative of the AI arms race, a low - buying strategy for tin prices is recommended [7]. Aluminum - Alumina prices are expected to continue to fluctuate widely around the industry cost line. Aluminum prices have experienced an emotional surge, but they have deviated from fundamental support. It is recommended to gradually make long positions after the price stabilizes and the volatility decreases [9]. Nickel - Recent macro - sentiment and ore - end expectations affect the overall fluctuation rhythm of nickel prices. Nickel prices are expected to adjust in a wide range. Pay attention to the range of 130,000 - 140,000 [11]. Stainless Steel - Stainless steel mainly follows the macro - sentiment. The cost support still exists, but the supply contraction due to steel mill production cuts, the weak demand boost in the off - season, and inventory digestion are still insufficient. It is expected to adjust weakly in the short term [13]. Industrial Silicon - Industrial silicon prices are expected to oscillate, with the main price fluctuation range between 8,200 - 9,200 yuan/ton. Pay attention to the changes in production and demand [15]. Polysilicon - Production enterprises have a strong willingness to support prices. Polysilicon prices are expected to stabilize and oscillate. Pay attention to the post - Spring Festival production reduction and downstream demand recovery [17]. Aluminum Alloy - The ADC12 price of aluminum alloy is expected to continue to oscillate in the high - level range. Pay attention to the actual circulation of scrap aluminum, the change of import window, and the final strength and rhythm of downstream inventory preparation before the Spring Festival [18]. Lithium Carbonate - The trading logic of lithium carbonate has switched, and the macro impact is greater. The price center has a certain constraint on the downward adjustment space. It is expected to adjust in a wide range in the short term [19]. 3. Summaries According to Relevant Catalogs Zinc - **Price and Spread**: SMM 0 zinc ingot price increased by 0.32% to 25,050 yuan/ton.

1. Report Industry Investment Ratings - No specific industry investment ratings are provided in the given reports. 2. Core Views of the Reports Tin - Short - term tin prices are highly volatile due to market sentiment, so it's advisable to participate with caution. In the medium - to - long - term, although the supply side is gradually recovering, considering the low elasticity of the supply end and the long - term narrative of the AI arms race, a low - buying strategy for tin prices is recommended [2]. Copper - In the short term, if the CL premium reverses, COMEX copper inventory may flow back to non - US regions, alleviating supply pressure there; if it remains narrow, copper prices may fluctuate in a wide range with limited upward potential, and if it widens, copper prices may maintain a relatively strong trend. In the medium - to - long - term, the price bottom is expected to rise gradually under the constraint of capital expenditure on the supply side, but current prices are suppressing downstream demand, and price fluctuations may intensify [3]. Zinc - The weakening of the US dollar index supports zinc prices. The shortage of zinc ore at the mine end supports prices, and the supply pressure of refined zinc is easing. The demand side has shown a significant recovery in the processing industry's operating rate after the price correction, and the terminal orders are stable. The global zinc ingot inventory pressure is limited. Short - term prices have limited downside space, and it is recommended to focus on the changes in zinc ore TC and refined zinc inventory, with the main contract supported at around 25,000 - 25,500 yuan/ton [5]. Industrial Silicon - The spot price of industrial silicon is stable, and the futures price has risen following commodities like coking coal. In January, both supply and demand have weakened slightly, with a slight inventory build - up. It is necessary to pay attention to the production reduction situation of industrial silicon. The price is expected to fluctuate in the range of 8,200 - 9,200 yuan/ton, with the upper limit pressured by the opening of the arbitrage window and the lower limit supported by costs [7]. Polysilicon - The polysilicon spot price is stable, but downstream components and battery cells are still reducing production despite price increases and increased exports due to weak domestic demand and the approaching Spring Festival. The demand for polysilicon is low, and the price is under pressure. In February, there is still pressure to reduce production. It is recommended to wait and see, focusing on the production reduction process and downstream demand recovery [8]. Aluminum - The alumina market is affected by the overall risk - preference recovery in the commodity market and supply - contraction expectations, but the high - inventory pressure in the domestic spot market still suppresses prices. It is expected to continue to fluctuate widely around the industry's cash - cost line. The aluminum market has shown a high - level breakthrough, but the domestic fundamentals are under pressure. In the medium - to - long - term, aluminum prices are expected to be strong and difficult to fall, but there is a risk of a high - level correction in the short term [9]. Aluminum Alloy - The casting aluminum alloy market has followed the rise in aluminum prices but lacks financial attributes and has poor downstream acceptance. The cost is the main driving factor, and the fundamentals show a typical seasonal supply - and - demand weakness. It is expected that the ADC12 price will continue to oscillate in the high - level range of 22,500 - 24,500 yuan/ton in the short term [11]. Nickel - The nickel market is supported by the strong performance of the non - ferrous sector and the smelters' hoarding mentality due to the expected tight supply of raw materials. In the short term, the price is expected to oscillate strongly in the range of 145,000 - 155,000 yuan/ton [12]. Stainless Steel - The stainless - steel market is driven by the strong commodity sentiment and the improvement in fundamentals due to steel - mill production cuts. In the short term, it is expected to adjust in a strong - oscillation pattern, with the main contract in the range of 14,200 - 15,200 yuan/ton. It is necessary to pay attention to the news from the ore end and the dynamics of steel mills [14]. Lithium Carbonate - The lithium carbonate futures market has shown a weak adjustment. Although the fundamentals show certain inventory - reduction resilience during the off - season, which supports prices, there may be a short - term decline adjustment. It is recommended to operate cautiously in the range of 155,000 - 170,000 yuan/ton [17]. 3.

Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. Core Views Tin - Short - term tin prices are highly volatile due to market sentiment, so cautious participation is advised. In the medium - to - long - term, the supply side is gradually recovering, but considering the low elasticity of the supply side and the long - term narrative of the AI arms race, a low - buying strategy for tin prices is recommended [2]. Industrial Silicon - The spot price of industrial silicon is stable, and the futures price fluctuates, rising after a decline. The production in January and February is expected to decrease. The demand side is likely to decline slightly in January. The price of industrial silicon is expected to fluctuate, with the main price range between 8200 - 9200 yuan/ton. Attention should be paid to the changes in production on the demand side [3]. Polysilicon - The average spot price of polysilicon and the price of silicon wafers have declined. The demand expectation has improved, and component production may increase slightly, which is conducive to inventory digestion. However, polysilicon and silicon wafer prices are under pressure due to high inventory. The monthly average production in the first quarter is expected to drop to about 80,000 tons. The price may be supported at the 48,000 yuan/ton level, and even at 45,000 yuan/ton considering full - cost support [4]. Copper - Market speculative sentiment has eased, and copper prices fluctuated. Geopolitical factors affect market expectations of copper tariffs. The global visible inventory has reached a high level in recent years, and the return of COMEX copper inventory may ease the supply pressure in non - US regions. In the short term, copper prices may return to fundamental pricing, and in the long term, the price bottom center is expected to gradually rise. Attention should be paid to the CL premium and LME inventory changes, with support at 97500 - 98500 [5]. Zinc - Market speculative sentiment has eased, and zinc prices adjusted. The shortage of zinc ore supports prices, and the import window for zinc ore has opened. The supply pressure of refined zinc has been relieved. High zinc prices have suppressed demand, and the downstream operating rate has weakened. Zinc prices are expected to fluctuate in the short term, with support around 23,800. Attention should be paid to zinc ore TC and refined zinc inventory changes [9]. Aluminum - The alumina market showed a weak and volatile trend, with an oversupply situation. Alumina prices are expected to fluctuate widely around the industry's cash - cost line, with the main contract reference range of 2600 - 2900 yuan/ton. The aluminum market is in a high - level volatile pattern. Although macro and policy expectations are positive, the fundamentals are under pressure, with supply increasing and demand being suppressed. Aluminum prices are expected to remain volatile at a high level in the short term, with the main contract reference range of 23000 - 25000 yuan/ton [12]. Nickel - The nickel futures market was volatile. Macro factors and the situation of Indonesian nickel ore quotas affect the market. The overall spot transaction of refined nickel is average. The prices of nickel ore and nickel iron have increased. The demand for stainless steel in the off - season is weak, and the market cost is relatively limited. The inventory pressure has increased. The nickel price is expected to fluctuate widely, with the main contract reference range of 138000 - 148000 [13]. Aluminum Alloy - Cast aluminum alloy prices fluctuated at a high level, with cost being the main driving factor. The supply of scrap aluminum is still tight, and the fundamentals show a situation of weak supply and demand in the off - season. The social inventory has decreased slightly. The ADC12 price is expected to continue the high - level volatile pattern in the short term, with the main contract reference range of 22000 - 23500 yuan/ton [15]. Stainless Steel - Stainless steel prices showed a narrow - range fluctuation and then a late - session rally. Macro factors and raw material supply expectations affect the market. The raw material prices are expected to rise, the supply is relatively loose, and the demand is weak. The social inventory is decreasing, but the demand in the off - season is still insufficient. Stainless steel prices are expected to be strongly volatile in the short term, with the main contract reference range of 14200 - 15000 [16]. Lithium Carbonate - Lithium carbonate futures prices rose sharply. News about lithium concentrate auctions and mine supply fluctuations affected the market sentiment. The production is slightly increasing, and the supply is expected to decline during the pre - holiday maintenance period. The downstream demand shows certain resilience. Social inventory decreased last week. Lithium carbonate prices are expected to be strongly volatile in the short term, but chasing the rise requires attention to volatility and liquidity risks [20].
