1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views Copper - Copper prices strengthened due to improved market risk appetite following the Sino - US trade talks. Macro factors like tariff policies, overseas liquidity, and COMEX - LME spread are important. Fundamentally, tight copper ore supply supports prices, but high prices may suppress downstream demand. The main contract is expected to find support between 84,000 - 85,000 yuan/ton [1]. Aluminum - The alumina market remains weak, with supply pressure and weak demand. Spot prices are expected to be under pressure, with the main contract oscillating between 2,750 - 2,950 yuan/ton. Aluminum prices are expected to remain high and fluctuate, with the main contract in the range of 20,700 - 21,300 yuan/ton [3]. Aluminum Alloy - Casting aluminum alloy prices showed a strong - oscillating trend. Cost support is significant, but high inventory and policy uncertainty restrict price increases. The short - term ADC12 price is expected to maintain a strong - oscillating pattern, with the main contract in the range of 20,200 - 20,800 yuan/ton [4]. Zinc - Due to LME zinc market concerns and Sino - US trade talks, zinc prices rebounded. Supply is expected to be loose, and demand has no outstanding performance. Short - term prices may be driven by macro factors, but the upward elasticity is limited, with the main contract in the range of 21,800 - 22,800 yuan/ton [8]. Tin - Tin prices continued to oscillate at a high level. Supply is tight, and demand is weak. Future price trends depend on the recovery of Burmese tin ore supply in the fourth quarter [10]. Nickel - Nickel prices are expected to oscillate in the range of 120,000 - 126,000 yuan/ton. Macro factors are temporarily stable, cost has support, but inventory accumulation exerts pressure [12]. Stainless Steel - Stainless steel prices are expected to weakly oscillate, with the main contract in the range of 12,600 - 13,000 yuan/ton. There is cost support at the ore end, but demand during the peak season is not strongly boosted [14]. Lithium Carbonate - Lithium carbonate prices are expected to run strongly in the short - term, with the main contract in the range of 76,000 - 82,000 yuan/ton. The fundamentals have improved, with strong demand during the peak season and continued destocking [16]. 3.

1. Report Industry Investment Ratings - Not mentioned in the provided content 2. Report Core Views Copper - Copper prices strengthened due to improved market risk appetite after China and the US agreed to conduct economic and trade consultations. In the short - term, China - US talks boosted market sentiment, the Fed may stop shrinking its balance sheet, and the COMEX - LME spread widened. Fundamentally, tight copper ore supply supports prices, and high copper prices moderately suppress downstream demand. The terminal demand has strong resilience. The main contract is expected to be supported at 84000 - 85000 [1]. Aluminum - The alumina market remains weak, with supply pressure and weak demand. The futures price is expected to continue to be under pressure, with the main contract oscillating between 2750 - 2950 yuan/ton. Aluminum prices showed a strong - oscillating trend. With stable supply, resilient demand, and declining inventory, the short - term Shanghai aluminum is expected to maintain a high - level oscillation, with the main contract in the range of 20700 - 21300 yuan/ton [3]. Aluminum Alloy - Casting aluminum alloy followed the aluminum price and showed a strong - oscillating trend. Cost support is prominent, but high inventory and policy uncertainty restrict price increases. The short - term ADC12 price is expected to maintain a strong - oscillating pattern, with the main contract in the range of 20200 - 20800 yuan/ton [4]. Zinc - Due to concerns about the LME zinc market squeeze and China - US economic and trade consultations, the Shanghai zinc price rebounded. The supply is loose, and the demand is not outstanding. The short - term price may rise due to macro - drivers but will likely oscillate without a clear inflection point in the supply - loose logic, with the main contract in the range of 21800 - 22800 [8]. Tin - Tin supply is tight, and demand is weak. The tin price continues to oscillate at a high level. If the supply in Myanmar recovers smoothly in the fourth quarter, the tin price may weaken; otherwise, it is expected to continue to run strongly [10]. Nickel - The nickel market is in a state of high - level oscillation. Macro - factors are temporarily stable, and the cost has support, but inventory accumulation restricts the upside space. The main contract is expected to oscillate in the range of 120000 - 126000 [12]. Stainless Steel - The stainless - steel market showed a low - level upward repair. Macro - factors may bring policy expectations. The supply pressure is increasing, and demand improvement is not obvious. The short - term market is expected to oscillate weakly, with the main contract in the range of 12600 - 13000 [14]. Lithium Carbonate - The lithium carbonate market showed a significant upward trend. The supply - demand gap exists in the peak season, and demand is optimistic. The short - term market is expected to run strongly, with the main contract in the range of 76000 - 82000 yuan/ton [16]. 3.

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views of the Reports Copper - Copper prices were volatile yesterday. High prices are suppressing demand, but terminal demand remains resilient. The supply shortage of copper ore supports the price bottom. It is expected that the domestic refined copper production in October may decline month - on - month. Attention should be paid to the marginal changes in demand and the Sino - US tariff negotiations. The main contract is expected to find support between 84,000 - 85,000 yuan/ton [1]. Aluminum - The alumina market is weak, with supply pressure and weak demand. It is expected that the spot price of alumina will continue to be under pressure in the short term, with the main contract oscillating between 2,750 - 2,950 yuan/ton. Aluminum prices were slightly stronger yesterday. The supply is stable, and the demand shows resilience in the peak season. It is expected that Shanghai aluminum will maintain a high - level oscillation in the short term, with the main contract in the range of 20,700 - 21,300 yuan/ton [3]. Aluminum Alloy - Casting aluminum alloy prices were slightly stronger, with cost support. The supply is restricted by raw materials and policies, and the demand is moderately recovering. The inventory has started to decline slowly. It is expected that the ADC12 price will maintain a slightly stronger oscillation in the short term, with the main contract in the range of 20,200 - 20,800 yuan/ton [5]. Zinc - Due to concerns about a short squeeze in the LME zinc market, the Shanghai zinc price rebounded after hitting the bottom. The supply is abundant, but the increase in domestic zinc smelters in the second half of the year may be limited. The macro - economic environment with high probability of interest rate cuts supports the zinc price. The demand is not exceeding expectations. It is expected that Shanghai zinc will maintain an oscillation in the short term, with the main contract in the range of 21,800 - 22,800 yuan/ton [9]. Tin - The supply of tin ore is tight, and the supply side is strong. The demand is weak, and the new demand cannot make up for the decline in traditional consumption. The tin price continues to oscillate at a high level. Attention should be paid to the macro - economic changes and the supply recovery in Myanmar in the fourth quarter [11]. Nickel - The Shanghai nickel market had a narrow - range oscillation. The macro - economic risk has increased, and the ore end has some positive factors. The refined nickel production remains high, and the inventory is accumulating. It is expected that the market will oscillate in the short term, with the main contract in the range of 120,000 - 126,000 yuan/ton [13]. Stainless Steel - The stainless - steel market had a narrow - range oscillation. The macro - economic environment has some positive factors, but the nickel - iron price is under pressure, and the demand in the peak season is not strongly boosted. It is expected that the market will oscillate weakly in the short term, with the main contract in the range of 12,400 - 12,800 yuan/ton [16]. Lithium Carbonate - The lithium carbonate futures market was strong. The supply - demand gap remains after entering the peak season. The downstream demand is optimistic. The inventory is declining. It is expected that the market will run strongly in the short term, with the main contract in the range of 76,000 - 80,000 yuan/ton [18][20]. 3.

Report Industry Investment Ratings No relevant information provided. Core Views of the Report Copper - Copper prices were volatile yesterday, with high prices suppressing demand. In the macro - aspect, attention should be paid to tariff policies, overseas liquidity, and the COMEX - LME spread. In the fundamental aspect, tight copper ore supply supports the price bottom. High copper prices have a certain inhibitory effect on downstream demand, but terminal demand remains resilient. The main contract is expected to find support between 84,000 - 85,000 yuan/ton [1]. Aluminum - The alumina market remains weak, with supply pressure significant and demand weak. The aluminum market is expected to maintain a high - level shock in the short term, with the main contract ranging from 20,700 - 21,300 yuan/ton. Attention should be paid to macro - policy changes, downstream acceptance of high prices, and inventory depletion rhythm [3]. Aluminum Alloy - Casting aluminum alloy followed the aluminum price in a range - bound shock. Cost support is prominent, but high inventory and policy uncertainty pose constraints. The short - term ADC12 price is expected to maintain a strong shock, with the main contract ranging from 20,200 - 20,800 yuan/ton [5]. Zinc - Zinc prices were volatile. The supply - side logic of looseness has been transmitted from zinc ore to zinc ingots. Demand has no unexpected performance. The short - term price may rise due to macro - drivers but has limited upward elasticity. The main contract is expected to range from 21,500 - 22,500 yuan/ton [9]. Tin - The supply of tin ore remains tight, while demand is weak. Considering the strong supply - side influence, attention should be paid to buying points when the macro - sentiment falls. The subsequent trend depends on the recovery of Myanmar's supply in the fourth quarter [11]. Nickel - The nickel market is expected to be range - bound. Macro risks have increased, and there is some positive news from the ore end. However, inventory accumulation exerts pressure. The main contract is expected to range from 120,000 - 126,000 yuan/ton [13]. Stainless Steel - The stainless - steel market is expected to be weakly volatile in the short term. The main contract is expected to range from 12,400 - 12,800 yuan/ton. Attention should be paid to macro - expectations and steel - mill supply [14][16]. Lithium Carbonate - The lithium carbonate market is expected to be strong in the short term. The main contract is expected to range from 75,000 - 78,000 yuan/ton. Attention should be paid to macro risks [17][19].

Report Summary 1. Report Industry Investment Rating - Unilateral: Cautiously bearish. - Arbitrage: Neutral [5] 2. Core View - Zinc prices may face pressure due to increasing supply and potential disappointment in consumption during the peak season, but the impact of overseas inventories needs attention [4] 3. Summary by Related Catalogs Important Data - **Spot**: LME zinc spot premium is $136.85/ton. SMM Shanghai zinc spot price is 21,870 yuan/ton, with a premium of -40 yuan/ton; SMM Guangdong zinc spot price is 21,820 yuan/ton, with a premium of -100 yuan/ton; Tianjin zinc spot price is 21,870 yuan/ton, with a premium of -40 yuan/ton [1] - **Futures**: On October 20, 2025, the SHFE zinc main contract opened at 21,885 yuan/ton and closed at 21,855 yuan/ton, down 55 yuan/ton from the previous trading day. The trading volume was 86,404 lots, and the position was 65,610 lots. The highest price was 21,945 yuan/ton, and the lowest was 21,820 yuan/ton [2] - **Inventory**: As of October 20, 2025, the total inventory of SMM seven - region zinc ingots was 165,300 tons, an increase of 2,500 tons from the previous period. The LME zinc inventory was 37,325 tons, a decrease of 700 tons from the previous trading day [3] Market Analysis - There is restocking in the spot market as zinc prices fall, but social inventories are increasing and may exceed the five - year average. Spot liquidity has improved, but procurement remains cautious. The TC of domestic and imported zinc ores is rising, leading to higher smelting profits and continuous smelting enthusiasm. The supply is expected to increase, and the upward trend of TC is expected to continue.

1. Report Industry Investment Rating The given reports do not mention any industry investment ratings. 2. Report's Core Views Copper - Copper prices were volatile yesterday, with high prices suppressing demand. Macro - factors like the approaching China - US tariff extension deadline and the weak US employment report could drive short - term trading. The supply shortage of copper mines will support copper prices in the long - term. The main contract is expected to find support between 84,000 - 85,000 yuan/ton [1]. Aluminum - The alumina market continued to be weak, and the aluminum market was in an oversupply situation. The spot price of aluminum is expected to remain under pressure, with the main contract oscillating between 2,750 - 2,950 yuan/ton. The Shanghai aluminum is expected to maintain a high - level oscillation between 20,700 - 21,300 yuan/ton, supported by macro - easing expectations and a tight - balance fundamentals, but high prices are suppressing downstream procurement [3]. Aluminum Alloy - The price of cast aluminum alloy futures oscillated, with the main contract slightly down. Cost support was prominent, but supply was restricted by raw material shortages and unclear policies. Demand was moderately recovering, and inventory was increasing, suppressing price increases. The ADC12 price is expected to maintain a high - level oscillation between 20,200 - 20,800 yuan/ton [4]. Zinc - Zinc prices oscillated, with pressure above. The supply - side logic of zinc has shifted from mines to zinc ingots. The increase in zinc ingot production is limited. Demand did not exceed expectations. The Shanghai zinc is expected to remain oscillating between 21,500 - 22,500 yuan/ton [7]. Tin - The supply of tin mines remained tight, while demand was weak. The short - term macro - volatility is expected to increase. Consider buying on dips due to macro - sentiment drops. The future trend of tin prices depends on the supply recovery in Myanmar in the fourth quarter [9]. Nickel - The Shanghai nickel market oscillated narrowly. Macro - risks increased, and there were some positive factors in the mining end, but the supply is expected to be loose in the medium - term, restricting price increases. The main contract is expected to oscillate between 120,000 - 126,000 yuan/ton [11]. Stainless Steel - The stainless - steel market oscillated weakly. Macro - risks increased, raw material prices were firm, but the peak - season demand was not met, and inventory pressure was high. The main contract is expected to oscillate between 12,400 - 12,800 yuan/ton [13]. Lithium Carbonate - The lithium carbonate futures market oscillated. The supply - side situation was gradually becoming clear but with many uncertainties. Demand was robust, and the whole - chain inventory was decreasing. The short - term market is expected to oscillate, with the main contract price centered between 70,000 - 75,000 yuan/ton [17][19]. 3.

1. Report Industry Investment Ratings - There is no information provided regarding industry investment ratings in the reports. 2. Core Views Copper - Copper prices were volatile yesterday, with high prices suppressing demand. Macro factors include the approaching Sino - US tariff extension deadline and the unexpected decline in US ADP employment in September. Fundamentally, the shortage of copper ore supply is a long - term concern, and subsequent attention should be paid to demand changes and Sino - US tariff negotiations. The main support level is 84000 - 85000 yuan/ton [1]. Aluminum - The alumina market continued its weak operation, and the aluminum market remained in an oversupply situation, with spot prices expected to remain under pressure. The short - term main contract of aluminum may fluctuate in the 2750 - 2950 yuan/ton range. For aluminum, the price center of Shanghai aluminum futures has moved up, but high prices have suppressed spot purchases. The macro environment is favorable, and the fundamentals are in a tight - balance state. It is expected that Shanghai aluminum will maintain a high - level shock pattern in the short term, with the main contract reference range of 20700 - 21300 yuan/ton [3]. Aluminum Alloy - The price of cast aluminum alloy futures showed a volatile trend. Cost support is prominent, but supply is restricted by raw material shortages and unclear policies. Demand is in a mild recovery state, and inventories are accumulating. It is expected that the short - term ADC12 price will maintain a high - level shock, with the main contract reference range of 20200 - 20800 yuan/ton [4]. Zinc - Zinc prices were volatile, and there was still pressure above the price. Fundamentally, the supply - side logic has shifted from zinc ore to zinc ingots. The subsequent focus is on TC growth and inventory performance. In the short term, zinc prices may be driven up by macro factors but will likely maintain a shock pattern [7]. Tin - The supply of tin ore remains tight, while demand has not improved significantly. Considering the strong supply - side and macro - factor fluctuations, attention should be paid to buying opportunities when the macro - sentiment falls. The future trend of tin prices depends on the supply recovery in Myanmar in the fourth quarter [9]. Nickel - The Shanghai nickel market showed a narrow - range shock, and the market sentiment was weak. There are uncertainties in Sino - US tariffs and the Fed's interest - rate cut path. The supply of nickel ore is mixed, and the demand for stainless steel and nickel sulfate is not strong. It is expected that the market will fluctuate in the range of 120000 - 126000 yuan/ton [11]. Stainless Steel - The stainless - steel market maintained a weak shock, and traders were mainly waiting and watching. Macro factors have uncertainties, and raw - material prices are firm. The supply pressure is increasing, and the peak - season demand has not been realized. It is expected that the short - term market will be in a weak shock adjustment, with the main operation range of 12400 - 12800 yuan/ton [13]. Lithium Carbonate - The lithium - carbonate futures market was in an overall shock state. The supply - side has information uncertainties, while the demand is steadily optimistic. The fundamentals are in a tight - balance state during the peak season, and the whole - chain inventory is decreasing. It is expected that the short - term market will maintain a shock adjustment, with the main price center of 70000 - 75000 yuan/ton [17][19]. 3.

1. Report Industry Investment Ratings No industry investment ratings were provided in the reports. 2. Core Views Copper - The US dollar index rebounded near 100, and copper prices fluctuated weakly. Near the Sino - US tariff extension deadline, tariff rhythm may drive short - term trading. The weak US employment data led to expectations of Fed monetary easing. The widening COMEX - LME spread attracted non - US copper to the US. - The shortage of copper mine supply is a key concern. Mines like Grasberg, Kamoa - Kakula, and El Teniente have had disruptions, which will support copper prices in the medium - to - long term. Focus on demand changes and Sino - US tariff negotiations, with support at 84000 - 85000 [1]. Aluminum - Alumina futures prices continued to decline, and the spot market was weak. With sufficient supply, high operating capacity, and increasing overseas supply, while demand was weak, the alumina market is expected to remain in surplus, with the main contract oscillating between 2800 - 3000 yuan/ton. - The center of gravity of Shanghai aluminum futures prices moved up, with a tight - balance fundamental situation. Macro - level factors are positive, but high prices suppress downstream procurement. It is expected to maintain high - level oscillations, with the main contract in the 20700 - 21300 yuan/ton range [3]. Aluminum Alloy - Casting aluminum alloy futures prices oscillated with aluminum prices. Cost support was strong due to rising scrap aluminum prices. Supply was affected by raw material shortages and unclear tax policies, while demand showed a mild recovery. Inventory was increasing, and imports were limited. It is expected that the ADC12 price will maintain high - level oscillations, with the main contract in the 20200 - 20800 yuan/ton range [4]. Zinc - Zinc prices oscillated, with pressure above. The supply - side logic of looseness has been transmitted from zinc mines to zinc ingots. The increase in zinc ingot production is limited by factors such as TC and sulfuric acid prices. Demand was not outstanding. It is expected to maintain oscillations, with the main contract in the 21500 - 22500 yuan/ton range [7]. Tin - Tin prices were affected by supply and demand. Supply of tin ore was tight, and smelting processing fees were low. Demand in traditional sectors was weak, although some consumption was driven by AI and photovoltaics. Considering the strong supply - side and macro - level uncertainties, focus on the buying point when the macro - sentiment drops. The future trend depends on the supply recovery in Myanmar [9]. Nickel - Shanghai nickel futures oscillated weakly. Macro - level factors were uncertain, including Sino - US tariffs and Fed policies. Spot nickel prices declined slightly, and downstream procurement increased. Nickel ore prices were firm, and nickel - iron prices were under pressure. It is expected to oscillate strongly, with the main contract in the 120000 - 126000 yuan/ton range [11]. Stainless Steel - Stainless steel futures prices oscillated downward. Macro - level risks were amplified, and raw material prices provided cost support. Demand in the peak season did not materialize, and inventory pressure increased. It is expected to oscillate weakly, with the main contract in the 12400 - 12800 yuan/ton range [13]. Lithium Carbonate - Lithium carbonate futures prices oscillated strongly. The fundamental situation was in a tight - balance during the peak season. Production increased, demand was optimistic, and the entire industry chain continued to reduce inventory. It is expected to oscillate, with the price center in the 70000 - 75000 yuan/ton range [15]. 3.
