1. Report Industry Investment Rating - The report does not explicitly mention an overall industry - wide investment rating. However, for each metal, it provides a mid - to long - term outlook, including "oscillation", "oscillation - weakening", etc., which can be roughly understood as a short - to medium - term investment view. For example, copper, aluminum, lead, stainless steel, and tin are expected to oscillate; zinc and nickel are expected to oscillate weakly; and the outlook for alumina and aluminum alloy is more specific with trading strategies [5][8][12]. 2. Core Viewpoints - The colored metals market is influenced by a combination of a weak US dollar, low LME inventories, and weakening demand, leading to continued oscillation. In the short - to medium - term, focus on structural opportunities and cautiously consider short - term long opportunities for copper, aluminum, and tin. In the long - term, there is uncertainty in the demand outlook for base metals, and it is advisable to look for opportunities to short on rallies for some metals with oversupply or expected oversupply [1]. 3. Summary by Relevant Catalogs 3.1 Copper - **Current Situation**: The US May labor market data was better than expected, with non - farm payrolls increasing by 139,000. Global copper mining giant Antofagasta initiated mid - year negotiations with Chinese and Japanese smelters. In May, SMM China's electrolytic copper production increased by 1.26 million tons month - on - month and 12.86% year - on - year. As of June 9, copper inventory in mainstream regions in China rose to 149,500 tons. The US increased the tariff on imported steel and aluminum and their derivatives from 25% to 50% [5]. - **Main Logic**: The US manufacturing activity contracted for the third consecutive month in May, and overseas economies are at risk of further weakening. On the supply side, copper concentrate processing fees have continued to decline, and raw material supply is still tight. Some smelters at home and abroad have announced maintenance and production cuts. On the demand side, with the arrival of the consumption off - season, downstream restocking willingness has weakened, and domestic social inventories have started to rise, limiting the upward space for copper prices [5]. - **Outlook**: Copper supply constraints still exist, and inventories are at a low level, supporting the bottom of copper prices. It is expected that copper will show high - level oscillation in the short term [5]. 3.2 Alumina - **Current Situation**: On June 10, the northern spot comprehensive price of alumina dropped by 15 yuan to 3,280 yuan, and the national weighted index dropped by 41.4 yuan to 3,260.8 yuan. An electrolytic aluminum plant in the northwest region tendered to purchase 10,000 tons of alumina, and a plant in Guangxi purchased 2,000 tons. Indonesia's Bintan Alumina Company's Phase III project entered the trial production stage, and a mining license in Guinea was revoked [5]. - **Main Logic**: In the short - to medium - term, there is no shortage of ore. With the repair of previous spot - futures profits, an increase in operating capacity and an inventory inflection point are expected. Long - term news is frequent, but the impact is expected to be limited if not fermented on the basis of red mud. The market has relatively fully priced in the news of the revoked mining license in Guinea and is becoming desensitized to it [5][6]. - **Outlook**: The logic of near - month production resumption is more certain than that of far - month ore supply. Given the current back structure, consider rolling into 7 - 9/7 - 1 reverse spreads. Aggressive investors can short contract 07 on rallies [6]. 3.3 Aluminum - **Current Situation**: On June 10, the average price of SMM Shanghai aluminum ingot spot was 20,160 yuan/ton, a decrease of 50 yuan/ton. As of June 9, the inventory of electrolytic aluminum ingots in mainstream consumption areas in China was 477,000 tons, a decrease of 42,000 tons, and the aluminum rod inventory was 129,500 tons, an increase of 1,800 tons. Some electrolytic aluminum enterprises in Sichuan are resuming production [7]. - **Main Logic**: Trump's increase in steel and aluminum tariffs has intensified global trade tensions. On the supply side, the spot price of upstream alumina has declined, and the profit of electrolytic aluminum enterprises has remained high. Overseas, the import of electrolytic aluminum into China is at a loss, and the supply growth space is limited. On the demand side, downstream demand has strengthened. In the long - term, domestic supply pressure is limited, and demand is expected to be cautiously optimistic, with the aluminum market in a tight - balance state [8]. - **Outlook**: Downstream demand has slightly increased, and it is expected that inventories will decline in the future. It is recommended to go long on dips, and aluminum prices are expected to oscillate [8]. 3.4 Aluminum Alloy - **Current Situation**: On June 10, the price of Baotai ADC12 remained unchanged at 19,400 yuan/ton. The SMM AOO average price was 20,160 yuan/ton, a decrease of 50 yuan. The difference between Baotai ADC12 and AOO was - 760 yuan/ton, an increase of 50 yuan [8]. - **Main Logic**: In the short - to medium - term, the pressure of the automotive off - season is high, ADC12 is weak, and the electrolytic aluminum inventory is low with firm prices. ADC12 - AOO may still weaken. In the long - term, the demand for ADC12 is expected to seasonally recover in the third quarter, and there is an expectation of an increase in ADC12 and ADC12 - AOO [9][11]. - **Outlook**: In the short term, ADC12 oscillates weakly. In the long term, ADC12 and ADC12 - AOO are expected to rise [11]. 3.5 Zinc - **Current Situation**: On June 10, the spot premium of Shanghai 0 zinc to the main contract was 295 yuan/ton, and that of Guangdong 0 zinc was 285 yuan/ton. As of June 10, the total inventory of SMM seven - region zinc ingots was 81,700 tons, an increase of 2,400 tons from last Thursday. Kipushi Mine is expected to produce 50,000 - 70,000 tons of zinc concentrate [10][11]. - **Main Logic**: The US tariff policy is volatile, and macro - uncertainty remains. On the supply side, the short - term supply of zinc ore has become looser, domestic zinc ore processing fees have increased, and smelters have started to make profits and increase production willingness. On the demand side, domestic consumption has entered the traditional off - season, and terminal new orders are limited. In the long - term, zinc supply is expected to increase, while demand growth is small, and supply will remain in oversupply [12]. - **Outlook**: After annual maintenance, zinc ingot production has increased again, downstream demand has gradually weakened, and inventories have accumulated. Zinc prices are expected to oscillate weakly in the short term and continue to decline in the long term [12]. 3.6 Lead - **Current Situation**: On June 10, the price of waste electric vehicle batteries was 10,125 yuan/ton, and the difference between primary and recycled lead was 25 yuan/ton. The average price of SMM1 lead ingot was 16,625 yuan, an increase of 100 yuan. The social inventory of lead ingots in major domestic markets decreased by 500 tons to 53,400 tons, and the latest Shanghai lead warehouse receipts increased by 399 tons to 42,198 tons [12][13]. - **Main Logic**: On the spot side, the spot discount was stable, and the difference between primary and recycled lead increased slightly. On the supply side, the price of waste batteries was stable, the lead price rose, the loss of recycled lead smelting narrowed, and some enterprises reduced production due to environmental inspections. On the demand side, affected by the Dragon Boat Festival holiday, the operating rate of lead - acid battery manufacturers decreased last week, but the operating rate was higher than the same period in previous years due to the "trade - in" activities in the automotive and electric bicycle markets [13]. - **Outlook**: After the Geneva negotiations, Sino - US tariffs have decreased significantly. In terms of supply and demand, the demand off - season has arrived, and battery dealers' finished product inventories are high, but the electric bicycle market's "trade - in" activities may keep the battery factory operating rate better than in previous years. The supply of lead ingots may remain stable this week. The price of waste batteries is likely to rise, and the cost of recycled lead provides high - level support. Lead prices are expected to oscillate [14][15]. 3.7 Nickel - **Current Situation**: On June 10, the LME nickel inventory was 198,126 tons, a decrease of 966 tons from the previous trading day, and the Shanghai nickel warehouse receipts were 21,041 tons, a decrease of 151 tons. Indonesia and France agreed to strengthen cooperation in key minerals, and BHP renewed an exploration agreement in Norway. Indonesia plans to reduce fuel imports from Singapore and has proposed a strategy to stabilize mineral and coal prices. The production of hydroxide precipitates in Indonesia's Morowali Industrial Park has declined [15][16][17]. - **Main Logic**: Market sentiment still dominates the market, and the static valuation of the market is stable. The industrial fundamentals are showing marginal weakness. The ore end is relatively strong, but the rainy season may restrict raw materials. The production of intermediate products has recovered, the price of nickel salts has slightly declined, the profit of salt factories has slightly improved, and the production of nickel sulfate from nickel beans is still at a loss. The supply of electrolytic nickel is in serious excess, and inventories have accumulated significantly [18]. - **Outlook**: The US reciprocal tariffs have led to a systematic price decline. In the long term, short on rallies. In the short term, nickel prices will oscillate widely [18]. 3.8 Stainless Steel - **Current Situation**: The latest stainless steel futures warehouse receipt inventory was 120,039 tons, a decrease of 1,624 tons from the previous trading day. On June 10, the spot premium of Foshan Hongwang 304 to the stainless steel main contract was 540 yuan/ton. In May, the national nickel pig iron production increased, and it is expected to decrease in June. The production of high - carbon ferrochrome increased in May. The national stainless steel production decreased slightly in May [20][21]. - **Main Logic**: The price of nickel iron has declined slightly, and the price of ferrochrome has weakened marginally. The 300 - series stainless steel is still in an inverted situation, putting pressure on steel mills. In May, stainless steel production decreased slightly, and it is expected to further decrease in June. Demand is gradually moving out of the peak season, and there is a risk of weakening apparent demand. The social inventory has decreased, and the warehouse receipt reduction is significant, alleviating the structural oversupply pressure [22]. - **Outlook**: The cost side still supports steel prices, but the market's acceptance of prices is limited. Demand moving out of the peak season also puts pressure on steel prices. Future focus should be on inventory changes and cost - side changes. Stainless steel is expected to oscillate within a range in the short term [22]. 3.9 Tin - **Current Situation**: On June 10, the LME tin warehouse receipt inventory decreased by 25 tons to 2,415 tons, and the Shanghai tin warehouse receipt inventory decreased by 38 tons to 6,866 tons. The Shanghai tin open interest increased by 107 lots to 50,717 lots. The average price of Shanghai Non - ferrous Metals Network 1 tin ingot was 264,800 yuan/ton, an increase of 900 yuan/ton [22][23]. - **Main Logic**: The previous sharp decline in tin prices may be due to short - sellers entering the market in advance under long - term pessimistic expectations, and the rumor of Wa State's resumption of production was just a trigger. In the short term, after the over - decline and the news of a slow resumption of production, the price rebounded. With Wa State's tin production not yet resumed, the domestic ore supply is tight, and the supply - demand fundamentals of tin are resilient. However, the easing of supply - side disturbances and the less - optimistic long - term demand outlook limit the upward elasticity of tin prices [23]. - **Outlook**: News from Wa State has increased tin price volatility. The tight ore supply provides support for tin prices. Whether the tight ore supply can further accelerate the transmission to the ingot end will determine the height of tin prices in June. Tin prices are expected to oscillate [23].
