1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Tin Industry - The market sentiment is overly high recently, and there is a risk of a decline. Attention should be paid to the macro - situation and the supply - side recovery [2]. Aluminum Alloy Industry - The strong cost and weak demand make the price of ADC12 have limited upward and downward space. It is expected to continue to fluctuate in a high - level range in the short term, with the main contract reference range of 20800 - 21800 yuan/ton [4]. Aluminum Industry - For alumina, the policy is more sentiment - driven and difficult to reverse the supply - demand fundamentals in the short term. The price is expected to fluctuate widely around the industry cash cost line. It is recommended to wait and see, with the main contract reference range of 2650 - 2950 yuan/ton. For electrolytic aluminum, the market is dominated by the game between strong macro - expectations and weak fundamentals. The price is expected to remain in a high - level wide - range fluctuation in the short term, with the main contract reference range of 21800 - 22800 yuan/ton [5]. Zinc Industry - The short - term zinc price is expected to fluctuate. The support comes from the tight domestic zinc ore supply and low zinc ingot inventory, while the pressure comes from the expected supply of imported ores. Attention should be paid to the import profit and loss, TC inflection point, and refined zinc inventory changes, with the main contract focusing on the 22850 - 22950 support [7]. Copper Industry - The medium - and long - term fundamentals of copper are good, but the short - term price is over - estimated to some extent. In a market with high speculative sentiment and risk preference, the price may remain strong in the short term. It is not advisable to short on the left side before the bullish logic reverses and the price shows a peak signal. Attention should be paid to overseas inventory changes and CL premium changes [10]. Lithium Carbonate Industry - The short - term supply is expected to increase slightly, and the downstream demand maintains a certain resilience. The destocking has slowed down. The price may remain strong in the short term under the support of capital sentiment, but attention should be paid to the risk of regulatory tightening and profit - taking adjustment of funds [14]. Nickel Industry - The expectation of increased nickel ore control in Indonesia drives the recent sentiment to strengthen, but the short - term reality is still weak, and the medium - term fundamentals are loose, which restricts the upward space of the price. The disk is expected to maintain a strong - side fluctuation in the short term, with the main contract reference range of 123000 - 130000 [15]. Stainless Steel Industry - The supply pressure has eased slightly, and the cost support of ore and ferronickel has strengthened, but the demand boost in the off - season is still insufficient. The short - term market sentiment is boosted, but the supply - demand game continues. It is expected to fluctuate and adjust in the short term, with the main contract reference range of 12500 - 13200 [17]. Industrial Silicon Industry - The supply and demand of industrial silicon are both stable with a downward trend, and the expectation of production reduction is further heating up. The price is expected to fluctuate at a low level, with the main price fluctuation range of 8000 - 9000 yuan/ton. Attention should be paid to the production reduction intensity [20]. Polysilicon Industry - The polysilicon price remains in a high - level shock. In January, under the background of weak demand, there is further production reduction pressure if supply - demand balance is to be achieved. It is recommended to wait and see, paying attention to the production reduction situation and price adjustment acceptance [21]. 3.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views Copper - Overseas inventory is structurally imbalanced, and terminal demand is significantly suppressed. The copper price continued to rise yesterday, with short - term price fluctuations intensifying. - The high copper price is mainly driven by supply and inventory structural imbalances and Fed's actions. Although the 2026 long - term TC is 0, smelters can maintain cash - flow profit if by - product profits are high enough. - SMM expects China's electrolytic copper production to rise in December, with sufficient spot supply. High prices have suppressed terminal demand, leading to a large discount in spot this week, inventory accumulation, and weakened downstream开工率 and order release. - The upward drivers are further deterioration of overseas inventory structure and improved interest - rate cut expectations; the downward driver is weak demand. The short - term price is volatile, and the main contract should focus on the 95,500 support level [1]. Aluminum - Alumina futures maintained a low - level oscillation. The fundamental pattern of oversupply has not improved. The supply is rigid, and the whole - industry chain inventory has reached a new high, forming a self - strengthening mechanism. The cost support level is moving down. Alumina prices are expected to oscillate around the cash - cost line, with the main contract reference range of 2,450 - 2,650 yuan/ton. - Electrolytic aluminum futures maintained a high - level oscillation. The macro environment is favorable, but the demand is in the off - season, and the inventory is accumulating. Aluminum prices are expected to oscillate widely in the short term, with the main contract reference range of 21,800 - 22,600 yuan/ton [3]. Aluminum Alloy - The casting aluminum alloy market showed a strong - oscillation trend. The core contradiction is the game between strong cost support and weakening demand. - The supply of scrap aluminum is tight, and the procurement cost is high. The high aluminum price has suppressed the purchasing willingness of downstream die - casting enterprises. - The social inventory has been decreasing slightly for several weeks. The ADC12 price is expected to oscillate in a high - level range, with the main contract reference range of 20,800 - 21,600 yuan/ton [5]. Zinc - The TC has stopped falling and stabilized, and the terminal demand is weak. The zinc price is oscillating weakly. - Domestic zinc ore production has decreased in November, and the import window has opened.

The social inventory has been decreasing, but the overall demand is general at the end of the year. The LME inventory has increased significantly, and the squeeze - out risk has eased. The main contract should focus on the 22,850 - 22,950 support level [9]. Tin - The supply of tin ore is expected to recover, and the export volume of Indonesia has increased significantly in November. - The tin - soldering enterprises in South China show certain resilience, while those in East China are more restricted. - The supply in Myanmar and Indonesia shows improvement signs. The previous long positions should be gradually closed, and subsequent macro and supply - side recovery should be monitored [11]. Nickel - The nickel futures price fell slightly. The market is trading around the expectation of tightened nickel ore supply. - The domestic spot nickel price has decreased, and the spot trading is average. The supply of Jinchuan electrolytic nickel is still tight. - The supply of nickel ore from the Philippines has decreased, and the Indonesian ore production target in 2026 has been significantly reduced.

The short - term price is expected to oscillate and recover, with the main contract reference range of 123,000 - 130,000 yuan/ton [12]. Stainless Steel - The stainless - steel futures price oscillated narrowly. The spot market's inquiry atmosphere has cooled, and the trading volume is average. - The Fed has cut interest rates, and the domestic central bank has injected liquidity. The market expects tightened nickel ore supply. - The supply is at a relatively high level, but some enterprises may conduct annual maintenance at the end of the year. The demand is in the off - season, and the social inventory is decreasing but still at a high level. - The short - term market sentiment has improved, but the supply - demand game continues. The price is expected to oscillate and adjust, with the main contract reference range of 12,500 - [missing in the report] [14]. Lithium Carbonate - The lithium carbonate futures price oscillated widely. The main contract LC2605 rose 0.44% to 123,520. - The recent news is abundant. Some production lines of Hunan Yueneng will be under maintenance in January, and Wanrun New Energy will reduce production for maintenance. - The current fundamentals show both supply and demand growth. The production is expected to increase in December, and the demand maintains certain resilience. The inventory has decreased significantly.

Report Industry Investment Rating The report does not provide an overall investment rating for the industry. Core Viewpoints - The non - ferrous metals sector is strong but volatile. The overall direction of monetary easing and ongoing contradictions in the mining end continue to support non - ferrous metals. However, due to factors such as capital outflows during Christmas, the sector experiences a round of strong consolidation. There are differences in fundamentals among non - ferrous metals, leading to a differentiation in strength. It is recommended to focus on opportunities where macro and micro factors resonate [12]. - Copper prices are expected to have an upward - moving central value in the future, driven by its financial attributes, valuation repair, and the global inventory structural contradiction. It is advisable to gradually go long on Shanghai Copper on dips [3]. - Zinc is in an oscillatory state. As long as the lower support level holds, one can go long on dips [4]. - For the aluminum industry chain, it is recommended to adopt a wait - and - see or long - biased approach. For alumina, a high - selling strategy is suggested [5]. - Tin is recommended to be on the sidelines, and attention should be paid to the trends of other non - ferrous metals and policy regulations [6]. - Lead shows a short - term upward trend, and one can go long on dips [8]. - Nickel and stainless steel are in a short - term bullish state, but attention should be paid to macro - liquidity changes and the implementation of Indonesian policies [9]. Summary by Section Part 1: Non - ferrous Metals Operating Logic and Investment Recommendations - **Macro Logic**: The non - ferrous metals sector is strong but volatile. Monetary easing continues, and contradictions in the mining end support the sector. Japan's intervention in the foreign exchange market weakens the US dollar, which is beneficial for non - ferrous metals. However, the appreciation of the RMB may lead to relatively stronger performance in the external market. During Christmas, capital outflows increase volatility, and non - ferrous metals experience a round of strong consolidation. The US economic data shows mixed performance, and China's economic data such as power consumption is positive. The non - ferrous metals sector has adjusted but moved away from lows, with internal differentiation in strength. Copper, with its tight supply - demand situation, drives the sector upward. As weak - performing varieties make up for losses, the sector may experience profit - taking and increased volatility. Attention should be paid to spot - market feedback [12]. - **This Week's Focus**: This week, the US will release a large amount of economic data, with the focus on the third - quarter real GDP on December 23. China will release the November industrial enterprise profit data on December 27. The Christmas holiday leads to market closures in the UK and the US [13]. - **Non - ferrous Metals Strategy** - **Copper**: Driven by factors such as the high - than - expected US GDP and inflation, and the global inventory structural contradiction, copper prices are expected to rise. It is advisable to go long on dips, with a short - term upper pressure range of 97,000 - 98,000 yuan/ton and a lower support range of 92,000 - 93,000 yuan/ton. Options strategies can consider buying near - month slightly out - of - the - money call options [3]. - **Zinc**: With a relatively warm macro environment and a slowdown in the decline of processing fees, zinc is in an oscillatory recovery state. It can be bought on dips as long as the support level holds, with an upper pressure range of 23,500 - 23,600 yuan/ton and a lower support range of 22,800 - 23,000 yuan/ton [4]. - **Aluminum Industry Chain**: For electrolytic aluminum, it is recommended to wait and see or go long on dips, with an upper pressure range of 23,000 - 24,000 yuan/ton and a lower support range of 21,000 - 21,300 yuan/ton. For alumina, a high - selling strategy is recommended, with an upper pressure range of 2,800 - 3,000 yuan/ton and a lower support range of 2,000 - 2,200 yuan/ton. For recycled aluminum alloy, a wait - and - see or long - biased approach is suggested, with an upper pressure range of 21,500 - 21,800 yuan/ton and a lower support range of 20,000 - 20,400 yuan/ton [5]. - **Tin**: Affected by sector adjustment, policy利空, and nickel market resonance, it is recommended to wait and see, with an upper pressure range of 350,000 - 355,000 yuan/ton and a lower support range of 310,000 - 320,000 yuan/ton. Options strategies can consider buying out - of - the - money put options for protection [6][7]. - **Lead**: With a weak US dollar and cost support, lead prices are rising. It is advisable to go long in the short term, with a lower support range of 16,700 - 16,800 yuan/ton and an upper pressure range of 17,200 - 17,300 yuan/ton [8]. - **Nickel and Stainless Steel**: Affected by the expected reduction of Indonesian nickel ore quotas and potential policy changes, nickel and stainless steel are short - term bullish. For nickel, the upper pressure range is 128,000 - 130,000 yuan/ton, and the lower support range is 123,000 - 124,000 yuan/ton. For stainless steel, the upper pressure range is 13,000 - 13,200 yuan/ton, and the lower support range is 12,500 - 12,600 yuan/ton [9].

1. Report Industry Investment Rating No relevant information provided. 2. Report Core Views Copper - Overseas inventory is structurally imbalanced, and terminal demand is significantly suppressed. Yesterday, copper prices continued to rise, with short - term price fluctuations intensifying. The high copper price is mainly driven by supply and inventory structural imbalances, and the Fed's actions support the price. SMM expects China's electrolytic copper production to rise in December, but high prices suppress demand, leading to inventory accumulation and weak downstream performance. The upward drive lies in further deterioration of overseas inventory structure and improved interest - rate cut expectations, while the downward drive is from weak demand. The short - term price is volatile, with the main focus on the 95,500 support level [1]. Aluminum - Alumina: The market has a supply - demand imbalance with stable supply growth and peaking demand, causing a negative feedback loop. Supply increases, leading to inventory accumulation and price decline. The price is expected to oscillate around the cash - cost line, with a reference range of 2,450 - 2,650 yuan/ton. Attention should be paid to environmental policies and enterprise production cuts [3]. - Electrolytic aluminum: The market is in a state of high - level oscillation. Macro - level overseas easing expectations and domestic positive policies support the price, but the supply increases, demand enters the off - season, and inventory accumulates. The price is expected to oscillate widely, with a reference range of 21,800 - 22,600 yuan/ton. Attention should be paid to macro - expectations and inventory changes [3]. Aluminum Alloy - The casting aluminum alloy market is in a state of oscillating and strengthening. The core contradiction is the game between strong cost support and weakening demand. The supply of scrap aluminum is tight, pushing up costs, while high aluminum prices suppress downstream demand. The ADC12 price is expected to oscillate in a high - level range of 20,800 - 21,600 yuan/ton. Attention should be paid to scrap - aluminum supply, environmental policies, and downstream orders [5]. Zinc - TC has stopped falling and stabilized, and terminal demand is weak, so zinc prices are oscillating weakly. Domestic zinc - ore production decreases in November, and the import window opens. Smelters cut production due to profit pressure, and refined - zinc production growth is limited. Downstream demand is generally weak at the end of the year, and social inventory is decreasing. The LME inventory increases, and the squeeze - out risk eases. The main support is at 22,850 - 22,950 [9]. Tin - The supply of tin ore is expected to recover, with increased imports in November and exports from Indonesia. The demand in South China shows some resilience, while that in East China is more restricted. The previous long positions should be gradually closed, and attention should be paid to macro - factors and supply - side recovery [11]. Nickel - The nickel market is in a state of short - term oscillation and repair. The market is trading around the expectation of tightened nickel - ore supply due to news from Indonesia. The domestic spot price falls, and the supply of refined nickel is tight. The price of nickel - iron has stronger bottom support. However, the short - term reality is weak, and the medium - term fundamentals are loose, restricting the upward price space. The main reference range is 123,000 - 130,000 [12]. Stainless Steel - The stainless - steel market is oscillating narrowly. The spot - market trading atmosphere is weak. The macro - environment is favorable, but the market has a strong expectation of tightened ore supply. The price of nickel - iron has stronger bottom support, and the supply pressure eases slightly. However, the demand is in the off - season, and high inventory remains a problem. The market is expected to oscillate and adjust, with a main reference range of 12,500 - [14]. Lithium Carbonate - The lithium - carbonate market is in a state of wide - range oscillation. The recent news is abundant, and the fundamentals are in a state of strong supply and demand. The production is expected to increase in December, and the demand has some resilience, but the power - market orders decline in the off - season. The inventory decreases, and the tight - balance fundamentals support the price, but there is limited new driving force [16]. Industrial Silicon - The industrial - silicon market has stable spot prices and oscillating futures prices. The supply and demand are both decreasing steadily, and the expectation of production cuts is rising. The demand from polysilicon is expected to decline significantly. The price is expected to oscillate at a low level, with a main range of 8,000 - 9,000 yuan/ton. Attention should be paid to the production - cut intensity [18]. Polysilicon - The polysilicon market has stable spot prices and a significant increase in futures prices. The exchange has introduced cooling measures. Upstream enterprises try to boost prices, but downstream profits are under pressure. The demand in the first quarter has no bright spots. The price is expected to remain high and oscillate, and attention should be paid to production cuts and price acceptance [19]. 3.

Core Viewpoint - The recent surge in tin prices is driven by multiple factors including the extension of a six-month ban on artisanal mining in the Democratic Republic of Congo, ongoing M23 conflicts, and slow recovery in Myanmar's mining sector, leading to record highs in tin prices [3][11]. Supply and Demand Analysis - Supply from major producing countries like the Democratic Republic of Congo and Myanmar is stabilizing, with exports from Wa State reaching nearly 1,000 tons per month. Domestic tin smelting capacity has been fully released, with refined tin production from January to November reaching 189,000 tons, a year-on-year increase of 6.2% [4][12]. - Both LME and SHFE tin inventories remain stable at around 10,000 tons, indicating no supply tightness. Despite growth in demand from emerging sectors like photovoltaics and automotive electronics, traditional sectors show stable demand, with global tin consumption expected to grow by nearly 3% in 2025, lagging behind production growth by about 0.5 percentage points [4][12]. Impact on Industry - The irrational price increase is disrupting the supply chain, causing challenges for upstream and downstream companies. Upstream firms may benefit in the short term, but volatility disrupts production planning and long-term investment decisions. Downstream users, particularly in solder, tinplate, and chemicals, face significant cost pressures, with some small to medium enterprises struggling to afford raw materials and fulfill long-term contracts [5][13]. - The electronic manufacturing sector, a major consumer of tin-based solder, is particularly affected, with rising costs in PCB manufacturing and semiconductor packaging severely eroding profits. Small electronic manufacturers are caught in a squeeze, facing soaring raw material prices while being unable to quickly raise end-product prices [5][13]. Long-term Risks - The volatility in tin prices poses a serious threat to the high-quality development of the tin industry. Unsustainable high prices may lead to a sharp decline once speculative funds withdraw, creating a rollercoaster effect that could further impact the entire supply chain. Speculative-driven price distortions hinder effective resource allocation, diverting focus from technological innovation and green transformation [6][14]. - The cyclical nature of price surges and drops undermines the overall risk resilience of the tin industry, which is crucial for establishing a stable and modern industrial system [6][14]. Strategic Importance of Tin - Tin is a critical strategic metal, essential for various sectors including electronic soldering, renewable energy, high-end equipment manufacturing, green tin plating, and national defense. The stability of tin supply and prices is directly linked to the stability and competitiveness of the domestic industrial chain [7][15]. - To maintain market order and create a stable environment, industry associations are calling for rational and cautious market behavior, urging stakeholders to avoid blind speculation and to collaboratively guide prices back to reasonable levels while improving long-term market mechanisms [7][15].

Core Viewpoint - The current tin market is experiencing a complex interplay of long-term structural shortages and short-term industrial realities, leading to a high price environment and significant market fluctuations [2] Group 1: Market Performance - The U.S. stock indices have risen, indicating a recovery in market risk appetite, while London tin prices increased by 0.13% to $42,975 per ton [1] - The Shanghai tin futures market opened higher, with the main contract 2601 reporting a rise of 1,260 yuan per ton, reflecting a 0.37% increase [1] Group 2: Supply and Demand Dynamics - The tin market is characterized by a long-term structural shortage due to declining resource grades and lengthy new capacity cycles, exacerbated by frequent disruptions in major producing countries [2][3] - Demand is shifting from traditional consumption, which is constrained by high prices, to emerging sectors like AI and renewable energy, which are driving up the premium for tin as a "high-tech metal" [2] Group 3: Industry Chain Status - The global tin industry chain is undergoing a profound reshaping, with upstream miners gaining significant bargaining power due to resource scarcity, while midstream smelting faces pressure from high raw material costs and low processing fees [3] - Downstream demand is diverging, with traditional sectors seeking material substitutes and process optimizations, while high-end manufacturing fields maintain strong demand for high-performance materials [3] Group 4: Price Outlook - Short-term tin prices are expected to oscillate between 325,000 and 340,000 yuan per ton, influenced by the interplay of strong expectations and weak realities [4] - In the medium to long term, the scarcity of resources and the ongoing demand from AI and green energy sectors are expected to support a systematic upward shift in price levels [4]

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Copper - The current high copper prices are mainly driven by the structural imbalance of supply and inventory. The COMEX - LME premium has led the US to continuously attract non - US copper resources, and the Fed's actions have boosted market risk appetite. - Concerns about the tightness of the ore end persist, and the tightness may be transmitted to the smelting end. High copper prices have suppressed terminal demand. - In the future, the imbalance of global copper supply and inventory and the tight ore end will limit the downside space of copper prices. Short - term price fluctuations may intensify, and the main support is at 90,000 - 91,000 yuan/ton [1]. Zinc - Domestic zinc mines are entering the production - reduction season, and the supply of refined zinc is gradually shifting from loose to tight. The export of zinc ingots has improved the market, and domestic spot zinc ingots remain at a premium. - The LME inventory has been accumulating, but the LME 0 - 3 premium remains high. The Fed's actions have boosted zinc prices. - In the future, the tightness of the ore end may lead to the tightness of zinc ingots. The short - term Shanghai zinc price may be stronger than the London zinc price. Pay attention to the inflection point of TC and the change in refined zinc inventory, with the main support at 23,000 - 23,200 yuan/ton [5]. Nickel - After the Fed's interest rate cut, the macro - sentiment has been digested, and there is limited further driving force after the valuation repair. The fundamentals are under pressure, and the nickel price is facing adjustment. - The spot nickel price has declined, and downstream demand is weak. Overseas inventory accumulation has slowed down, while domestic social inventory pressure has increased. - In the short term, the nickel price is expected to fluctuate weakly, with the main reference range of 114,000 - 118,000 yuan/ton. Pay attention to macro - expectations and Indonesian industrial policies [6]. Stainless Steel - The stainless - steel market has certain support from the supply and cost sides, but the off - season demand limits the upside space. - The nickel ore market is stable, and the nickel - iron and chromium - iron prices have different trends. The supply pressure is slightly relieved, but the demand is weak, and the inventory reduction is limited. - In the short term, stainless steel is expected to fluctuate and adjust, with the main operating range of 12,400 - 12,800 yuan/ton. Pay attention to the implementation of steel - mill production reduction and the marginal improvement of demand [9]. Tin - The supply of tin ore remains tight, and it is expected that the improvement of tin ore supply within the year will be limited. The demand in the South China region shows certain resilience, especially in the new - energy - related fields. - The market sentiment is positive, and the fundamentals are strong. It is expected that the tin price will maintain a strong trend within the year. Hold long positions and consider buying on dips [11]. Aluminum - The alumina market has a structural surplus, with stable supply growth and peak demand. The inventory has accumulated to a historical high, and the cost support has shifted downward. The short - term price may be volatile, and the reference range for the main contract is 2,500 - 2,700 yuan/ton. - The electrolytic aluminum market is in a high - level wide - range shock under the interweaving of macro - sentiment and fundamentals. It is expected to maintain a high - level shock pattern, with the main contract reference range of 21,500 - 22,300 yuan/ton. Pay attention to the Fed's policies and domestic inventory changes [12]. Aluminum Alloy - The price of cast aluminum alloy has remained high and volatile. The supply of scrap aluminum is tight, and the increase in the price of primary aluminum has increased the cost pressure on recycled aluminum plants. - The demand shows a marginal weakening trend, and the social inventory has decreased slightly. The ADC12 price is restricted by strong costs and weak demand, and it is expected to continue to fluctuate in a high - level range. The reference range for the main contract is 20,600 - 21,400 yuan/ton. Pay attention to scrap - aluminum supply, downstream orders, and macro - sentiment [13]. Industrial Silicon - The price of industrial silicon has weakened under the pressure of cost decline expectations, significant demand decline expectations, and continuous inventory increase. - It is expected that the supply - demand situation in December will remain weak. The price is expected to fluctuate at a low level, with the main price range of 8,000 - 9,000 yuan/ton. If production decreases significantly, it may reach 10,000 yuan/ton; otherwise, it may fall to 7,500 yuan/ton [15]. Polysilicon - The polysilicon price has shown a large - amplitude shock. Although the production has decreased, the demand has decreased more, resulting in an oversupply situation and continuous inventory accumulation. - After the registration of the platform company, the price may be strong under the influence of positive news. Pay attention to the substantial progress of capacity storage and production control. The futures price is strongly rising and at a large premium to the spot market. Pay attention to the production - reduction amplitude and price - decline pressure [16]. Lithium Carbonate - The futures price center of lithium carbonate has moved up, and there are more news disturbances in the market. The fundamentals remain in a situation of both supply and demand being strong. - The downstream demand is relatively optimistic, but the sustainability of the improvement in the off - season demand at the end of the year needs to be noted. The social inventory is stably decreasing, but the off - balance - sheet implicit inventory may bring pressure. - In the short term, the market may maintain a strong shock, with the main reference range of 95,000 - 100,000 yuan [17]. 3.
