Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Report Core Views - For copper, the price pulled back in the second half of the week, and the market sentiment cooled. In the short - term, negative factors are released, but the price is expected to rise in the medium - term as the fundamentals feature limited supply and increasing demand [1] - For aluminum, the basis and downstream processing fees are low, with continuous inventory accumulation. Domestic demand has short - term support, and overseas active restocking may support the price [1] - For zinc, the domestic fundamentals are average, but the market is optimistic about its allocation flexibility, and attention should be paid to reverse arbitrage and positive arbitrage opportunities [2] - For nickel, the short - term fundamentals are weak, and there is a game between short - term policies and fundamentals [3] - For stainless steel, the fundamentals remain weak, and the price is mainly driven by nickel price in the short - term [3] - For lead, the price oscillates at a high level.

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].
