1. Report Industry Investment Ratings No information provided in the reports regarding industry investment ratings. 2. Core Views Tin - Short - term price is highly volatile due to market sentiment. After a sharp decline on Friday night, it's advisable to be cautious in the short - term. Consider a low - buying strategy after the sentiment stabilizes [1]. Copper - In the long - term, the price bottom center is expected to rise due to capital expenditure constraints on the supply side. In the short - term, the price is strong because of global inventory structural imbalance and supply concerns. However, real terminal demand is weak. With the cooling of speculative sentiment and easing of tariff expectations, the price may return to fundamental pricing. Pay attention to CL premium and LME inventory changes, with the main contract supported at 97500 - 98500 [3]. Nickel - Recent trading is centered around macro and Indonesian ore RKAB quota. Short - term ore news has limited further driving force. The market is expected to fluctuate widely, with the main contract reference range of 135000 - 145000 [5]. Zinc - The price is supported by domestic ore shortage and pressured by expected imported ore supply and negative demand feedback. It is expected to fluctuate in the short - term. Focus on zinc ore TC and refined zinc inventory changes, with the main contract supported around 23800 [8]. Lithium Carbonate - The fundamentals show some resilience in the off - season. With a loose macro environment and strengthened supervision, there is resistance to further price increases. The market has intensified long - short divergence. The short - term market may adjust widely, with the main contract running between 140,000 - 150,000. Use short - term range trading [11]. Aluminum - Alumina prices lack upward momentum due to loose supply, weakening demand, and high inventory.

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.

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.
