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].

Core Viewpoint - The multi-crystalline silicon market remains in a wait-and-see attitude, with a weak balance between supply and demand gradually emerging [1][2]. Group 1: Market Prices - The transaction price range for n-type re-investment material is between 50,000 to 63,000 yuan per ton, with an average transaction price of 59,200 yuan per ton, remaining flat week-on-week [1]. - The transaction price range for n-type granular silicon is also between 50,000 to 63,000 yuan per ton, with an average transaction price of 55,800 yuan per ton, also remaining flat week-on-week [1]. - Despite slight price adjustments from some enterprises, the overall transaction prices in the mainstream market have remained stable [1]. Group 2: Market Dynamics - The current market stalemate is attributed to two main factors: first, while policies like export tax rebates for photovoltaic products provide medium to long-term demand support, some demand has been preemptively fulfilled by 2025, leading to a lack of willingness among downstream silicon wafer companies to increase operating rates, thus limiting immediate procurement demand for silicon materials [1]. - Second, the continuous surge in silver prices has significantly increased the production costs of battery cells and modules, making the slight price reductions in silicon materials have limited impact on downstream cost reductions [1]. - The low operating rates of multi-crystalline silicon enterprises have led to rising comprehensive costs, further reinforcing price bottom support [1]. Group 3: Production and Supply Outlook - According to production plans, several leading enterprises are expected to implement production halts or reductions in January, with the average monthly output of multi-crystalline silicon expected to drop to around 80,000 tons in the first quarter [2]. - Although there has not been a substantial recovery in terminal demand, the significant contraction in supply is gradually leading to a weak balance in supply and demand [2]. - The key variables affecting price trends in the short term include: first, substantial changes in downstream operating rates, particularly the effective transmission of order demand from the battery and module sectors to the silicon wafer sector; second, the sustainability of inventory reduction, as high inventory levels may continue to suppress prices if demand does not recover in a timely manner [2].

Core Viewpoint - The silicon market is experiencing a stalemate, with stable prices despite slight fluctuations in some companies' quotes, primarily due to preemptive demand and rising production costs from silver prices [1][2]. Group 1: Market Conditions - The overall trading atmosphere in the market is subdued, with new orders being scarce and transactions mainly consisting of tentative deals [1]. - The current market deadlock is attributed to two main factors: the preemptive demand for photovoltaic products and the reluctance of downstream silicon wafer companies to increase production rates [1][2]. - The average transaction price for n-type recycled silicon is reported at 59,200 yuan/ton, while n-type granular silicon is at 55,800 yuan/ton, both remaining stable week-on-week [1][3]. Group 2: Supply and Demand Dynamics - Several leading companies are expected to implement production cuts or halts in January, leading to an anticipated average monthly production of polysilicon around 80,000 tons in the first quarter [2]. - Despite the lack of substantial recovery in terminal demand, the significant reduction in supply is gradually leading to a weak balance in supply and demand [2]. - Key variables affecting price trends include changes in downstream operating rates and the sustainability of inventory reduction, with high inventory levels potentially suppressing prices if demand does not recover promptly [2]. Group 3: Price Statistics - The price statistics for domestic solar-grade polysilicon as of January 21, 2026, show the following: - n-type recycled silicon price range: 50,000 - 63,000 yuan/ton, average price: 59,200 yuan/ton [3]. - n-type granular silicon price range: 50,000 - 63,000 yuan/ton, average price: 55,800 yuan/ton [3]. - The prices are based on a weighted average from nine polysilicon production companies, which account for 89.3% of domestic production in Q4 2025 [3][4].

Group 1 - The core viewpoint of the article indicates that the market for polysilicon, particularly n-type materials, is currently stable with transaction prices holding steady despite slight fluctuations in individual company quotes. The average transaction price for n-type recycled material is 59,200 yuan/ton, while n-type granular silicon is at 55,800 yuan/ton, both showing no change compared to the previous period [1][2]. - The market atmosphere is described as quiet, with new orders being scarce and transactions primarily consisting of small, tentative deals. This stalemate is attributed to two main factors: first, some demand has been preemptively fulfilled by 2025, leading to a lack of urgency in procurement from downstream silicon wafer manufacturers; second, rising silver prices have significantly increased production costs for battery cells and modules, limiting the impact of slight price reductions in polysilicon on downstream costs [1][2]. - A significant reduction in polysilicon production is anticipated, with major companies planning to halt or reduce output in January, leading to an expected average monthly production of around 80,000 tons in the first quarter. Although terminal demand has not shown substantial recovery, the drastic supply contraction is expected to gradually lead to a weak balance in supply and demand [2][3]. Group 2 - The key variables influencing price trends in the polysilicon market include: first, any substantial changes in downstream operating rates, particularly the effective transmission of order demand from the battery and module sectors to the silicon wafer sector; second, the sustainability of inventory reduction, as high inventory levels could suppress prices if demand does not recover in a timely manner [2][3]. - The transaction price data for domestic solar-grade polysilicon indicates that the highest price for n-type recycled material is 63,000 yuan/ton, while the lowest is 50,000 yuan/ton, with an average price of 59,200 yuan/ton showing no fluctuation [3].

Copper - Overnight copper prices showed a downward trend, with domestic refined copper imports continuing to incur losses [3][12] - Macro factors include significant selling of long-term Japanese government bonds due to pre-election expectations and expansionary fiscal narratives, leading to market tension [3][12] - LME copper inventory increased by 8,875 tons to 156,300 tons, while SHFE copper warehouse receipts decreased by 4,462 tons to 148,193 tons [3][12] - Domestic copper consumption is entering a low season, with inventory accumulation stronger than in the past two years, indicating a need for adjustment [3][12] - Despite the current market conditions, there is still support from funds, making a significant price drop unlikely, with attention on the LME support level of $12,000 per ounce [3][12] Nickel & Stainless Steel - LME nickel fell by 2.12% to $17,760 per ton, while SHFE nickel dropped by 1.68% to 140,110 yuan per ton [4][13] - LME nickel inventory decreased by 972 tons to 284,736 tons, and SHFE warehouse receipts fell by 320 tons to 41,478 tons [4][13] - Indonesia plans to adjust nickel quotas based on industry demand to support local mineral prices, although specific quota levels for 2026 were not disclosed [4][13] - Primary nickel production increased significantly by 18.5% to 37,200 tons, with hedging demand potentially exerting pressure on prices [4][5][13] - Short-term nickel prices may be supported by Indonesian policies, but high inventory levels pose upward pressure [5][13] Aluminum & Alumina - Overnight alumina prices showed a slight decline, with AO2605 settling at 2,668 yuan per ton, down 0.85% [6][14] - SHFE aluminum prices also decreased, with AL2603 closing at 23,775 yuan per ton, down 1.02% [6][14] - The market is experiencing a high inventory level, and there is a lack of purchasing interest from alumina plants, leading to continued inventory accumulation [6][14] - Domestic downstream inventory is expected to continue accumulating, with a potential for short-term price corrections in aluminum [6][14] Industrial Silicon & Polysilicon - Industrial silicon prices showed a slight decline, with the main contract settling at 8,745 yuan per ton, down 0.4% [7][15] - Polysilicon prices remained strong, with the main contract at 50,700 yuan per ton, up 0.91% [7][15] - The market is shifting from speculative trading to a focus on fundamentals, with pressures on polysilicon prices due to supply-demand imbalances [7][15] Lithium Carbonate - Lithium carbonate futures reached a limit up at 160,500 yuan per ton, with battery-grade lithium carbonate prices rising by 1,500 yuan to 152,500 yuan per ton [8][16] - Weekly production increased by 115 tons to 22,535 tons, with various sources of lithium showing production increases [8][16] - Social inventory of lithium carbonate rose by 337 tons to 109,942 tons, indicating a mixed supply-demand situation [8][16] - The market is expected to maintain a bullish outlook unless clear negative feedback from demand emerges [8][16]
