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.

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - The threat of Trump to impose significant additional tariffs on China is uncertain, and market sentiment needs further clarification. For copper, overseas mine production cuts and reduced domestic refined copper output may support prices. If the trade situation is a short - term shock, there may be buying opportunities after the price decline [2][3]. - The deterioration of Sino - US trade relations is uncertain. For aluminum, if the tariff threat is short - term, market sentiment may recover. With the increase in the domestic aluminum - water ratio and seasonal consumption recovery, the pressure of aluminum ingot inventory accumulation is not large, and the price decline may increase the upward elasticity [5][6]. - For lead, the apparent inventory of lead ore has slightly increased, and the smelting of primary lead is at a high level. The inventory of recycled lead has decreased, and its smelting is at a low level. With the release of downstream demand and the increase in the cancellation of LME lead warehouse receipts, the structural risk of LME lead has increased. Short - term Shanghai lead is expected to fluctuate at a low level with increased risk [8][9]. - For zinc, domestic zinc smelting enterprises operate normally during holidays, and some downstream enterprises have long holidays. The registered LME zinc warehouse receipts are at a low level, and there is a structural risk. After the opening of the zinc ingot export window, short - covering in the domestic market provides short - term support. Short - term Shanghai zinc is expected to fluctuate at a low level with increased risk [10][12]. - For tin, short - term Sino - US trade frictions may lower market risk appetite, but the supply - demand is in a tight balance, and the peak - season demand is recovering. Tin prices may maintain a high - level shock in the short term [13][14]. - For nickel, short - term Sino - US trade frictions may lower market risk appetite, but the impact on nickel prices is relatively small. In the short term, it is recommended to wait and see, and consider buying on dips if the price drops enough. In the long - term, there are potential positive factors for nickel prices [15][17]. - For lithium carbonate, the strong downstream demand during the National Day holiday drives inventory reduction, but the supply replenishment expectation restricts the upside space. The negative sentiment in the equity market may suppress lithium prices, and it is recommended to pay attention to macro - environment changes and supply - demand expectations [19][20]. - For alumina, the short - term ore price has support but may face pressure after the rainy season. The over - capacity pattern in the smelting end is difficult to change in the short term. It is recommended to wait and see, and pay attention to supply - side policies, Guinea's ore policy, and the Fed's monetary policy [22][24]. - For stainless steel, the market is trapped between "cost support" and "weak demand". If the nickel - iron price continues to rise, stainless steel may oscillate upward under cost support [26][27]. - For cast aluminum alloy, the cost - end aluminum price weakens due to Sino - US trade relations, and the contract delivery pressure is large. However, with the improvement of downstream consumption and reduced raw - material supply, the price is expected to have support [29][30] Group 3: Summaries by Metals Copper - **Market Information**: Trump's tariff threat causes market panic, leading to a 3.73% drop in LME copper 3M to $10374/ton and a fall in SHFE copper to 83030 yuan/ton. LME copper inventory decreases by 75 to 139000 tons, and domestic SHFE inventory increases by 15000 tons compared to before the holiday [2]. - **Strategy Viewpoint**: The tariff threat is uncertain. From the fundamental perspective, supply tightening supports prices. If it's a short - term shock, there may be buying opportunities after the price decline. The operating range of SHFE copper is 82000 - 85500 yuan/ton, and that of LME copper 3M is $10200 - 10700/ton [3] Aluminum - **Market Information**: The deterioration of Sino - US trade relations causes aluminum prices to weaken. LME aluminum 3M drops 1.31% to $2746/ton, and SHFE aluminum closes at 20755 yuan/ton. Domestic aluminum ingot and billet inventories increase slightly, and the processing fee of aluminum billets declines [5]. - **Strategy Viewpoint**: If the tariff threat is short - term, market sentiment may recover. With the increase in the aluminum - water ratio and seasonal consumption recovery, the inventory accumulation pressure is not large, and the price decline may increase the upward elasticity. The operating range of SHFE aluminum is 20500 - 21100 yuan/ton, and that of LME aluminum 3M is $2700 - 2790/ton [6] Lead - **Market Information**: SHFE lead index rises 0.12% to 17142 yuan/ton, and LME lead 3S rises to $2027.5/ton. Domestic social inventory decreases to 3.58 tons [8]. - **Strategy Viewpoint**: The apparent inventory of lead ore increases slightly, and the smelting of primary lead is at a high level. The inventory of recycled lead decreases, and its smelting is at a low level. With the release of downstream demand and the increase in the cancellation of LME lead warehouse receipts, the structural risk of LME lead has increased. Short - term Shanghai lead is expected to fluctuate at a low level with increased risk [9] Zinc - **Market Information**: SHFE zinc index falls 0.18% to 22289 yuan/ton, and LME zinc 3S falls to $2997/ton. Domestic social inventory increases slightly to 15.02 tons [10]. - **Strategy Viewpoint**: Domestic zinc smelting enterprises operate normally during holidays, and some downstream enterprises have long holidays. The registered LME zinc warehouse receipts are at a low level, and there is a structural risk. After the opening of the zinc ingot export window, short - covering in the domestic market provides short - term support. Short - term Shanghai zinc is expected to fluctuate at a low level with increased risk [11][12] Tin - **Market Information**: Tin prices fall due to Sino - US trade frictions. The resumption of tin mines in Myanmar is slow, and Indonesia cracks down on illegal mining, increasing supply concerns. The downstream new - energy vehicle and AI server industries are booming, but traditional consumer electronics and photovoltaic industries are weak. The "Golden September and Silver October" peak season drives marginal improvement in consumption [13]. - **Strategy Viewpoint**: Short - term Sino - US trade frictions may lower market risk appetite, but the supply - demand is in a tight balance, and the peak - season demand is recovering. Tin prices may maintain a high - level shock in the short term. It is recommended to wait and see. The operating range of domestic tin is 280000 - 300000 yuan/ton, and that of LME tin is $36000 - 39000/ton [14] Nickel - **Market Information**: Nickel prices fluctuate and fall at night due to Sino - US trade frictions. The spot market trading is average, and the cost of nickel ore is stable. Nickel - iron prices are firm, and the price of MHP is high [15]. - **Strategy Viewpoint**: Short - term Sino - US trade frictions may lower market risk appetite, but the impact on nickel prices is relatively small. In the short term, it is recommended to wait and see, and consider buying on dips if the price drops enough. In the long - term, there are potential positive factors for nickel prices. The operating range of SHFE nickel is 115000 - 128000 yuan/ton, and that of LME nickel 3M is $14500 - 16500/ton [17] Lithium Carbonate - **Market Information**: On October 10, the MMLC spot index of lithium carbonate is flat at 73011 yuan.

The price of LC2511 contract falls 0.82% [19]. - **Strategy Viewpoint**: The strong downstream demand during the National Day holiday drives inventory reduction, but the supply replenishment expectation restricts the upside space. The negative sentiment in the equity market may suppress lithium prices. It is recommended to pay attention to macro - environment changes and supply - demand expectations. The operating range of the Guangzhou Futures Exchange's lithium carbonate main contract is 68800 - 73800 yuan/ton [20] Alumina - **Market Information**: On October 10, the alumina index falls 0.66% to 2861 yuan/ton. The spot price in Shandong falls to 2865 yuan/ton, and the overseas FOB price in Australia rises to $324/ton. The import window is close to closing, and the futures warehouse receipts increase [22]. - **Strategy Viewpoint**: The short - term ore price has support but may face pressure after the rainy season. The over - capacity pattern in the smelting end is difficult to change in the short term. It is recommended to wait and see. The operating range of the domestic main contract AO2601 is 2600 - 3000 yuan/ton, and attention should be paid to supply - side policies, Guinea's ore policy, and the Fed's monetary policy [23][24] Stainless Steel - **Market Information**: The stainless - steel main contract closes at 12860 yuan/ton, up 1.02%. The spot prices in Foshan and Wuxi are stable. The raw - material prices are stable, and the social inventory decreases [26]. - **Strategy Viewpoint**: The market is trapped between "cost support" and "weak demand". If the nickel - iron price continues to rise, stainless steel may oscillate upward under cost support [27] Cast Aluminum Alloy - **Market Information**: Aluminum alloy prices rise and then fall following aluminum prices. The AD2511 contract falls 0.41% to 20465 yuan/ton. The price of domestic mainstream ADC12 rises slightly, and the inventory of recycled aluminum alloy ingots in the main domestic markets decreases [29]. - **Strategy Viewpoint**: The cost - end aluminum price weakens due to Sino - US trade relations, and the contract delivery pressure is large. However, with the improvement of downstream consumption and reduced raw - material supply, the price is expected to have support [30]
