1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Copper: Overnight LME copper fluctuated narrowly, rising slightly by 0.01% to $9,567 per ton; SHFE copper main contract fell by 0.18% to 77,850 yuan per ton. The US macro situation is mixed, with the April existing - home sales index falling year - on - year. LME copper inventory decreased, Comex inventory increased, and SHFE copper warehouse receipts decreased. High copper prices and premiums made downstream procurement cautious. With a relatively stable macro situation and fundamental support, it's difficult for copper prices to drop significantly. The current weak market is due to the domestic off - season, and the de - stocking trend and high BACK structure are not suitable for unilateral short - selling. Copper may maintain the current oscillating trend [1]. - Aluminum: Alumina and Shanghai aluminum both fluctuated weakly. The spot price of alumina rose slightly, and the spot premium of aluminum ingots expanded. The cost center of aluminum has declined, and alumina enterprises are showing signs of resuming production. The turnover of aluminum ingots accelerated slightly before the holiday, and the downstream rigid demand for stocking was limited. Aluminum prices continued to adjust narrowly above 20,000 yuan and were not significantly affected by alumina [1][2]. - Nickel: Overnight LME nickel rose by 1.99%, and SHFE nickel rose by 1.25%. LME and domestic SHFE nickel inventories decreased. The cost support of the stainless - steel industry chain is strong, but market transactions are weak, and inventory digestion is mainly for 200 - series and 300 - series. In the new energy sector, raw material supply has increased, but the demand for nickel sulfate is hard to increase. After a rapid decline, nickel prices may recover, but in the short term, they will still oscillate [2]. 3. Summary by Relevant Catalogs 3.1 Research Views - Copper: Overnight LME copper rose slightly, SHFE copper fell. The US April existing - home sales index was far lower than expected. LME inventory decreased, Comex increased, and SHFE warehouse receipts decreased. High prices and premiums made downstream procurement cautious. The macro situation is improving, and the fundamentals support copper prices. It's difficult for prices to drop significantly, and the current weak market is due to the off - season. Copper may oscillate, and attention should be paid to capital games [1]. - Aluminum: Alumina and Shanghai aluminum fluctuated weakly. The spot price of alumina rose slightly, and the spot premium of aluminum ingots expanded. The cost of aluminum decreased, and alumina enterprises may resume production. The turnover of aluminum ingots accelerated before the holiday, and downstream stocking was limited. Aluminum prices adjusted narrowly above 20,000 yuan [1][2]. - Nickel: Overnight LME nickel and SHFE nickel rose. LME and domestic SHFE inventories decreased. The stainless - steel industry chain has strong cost support but weak transactions. In the new energy sector, supply increased while demand was weak. After a decline, nickel prices may recover but will oscillate in the short term [2]. 3.2 Daily Data Monitoring - Copper: The price of flat - water copper decreased, and the premium decreased. The price of scrap copper remained unchanged, and the refined - scrap price difference decreased.

LME inventory remained unchanged, and SHFE inventory decreased [3]. - Aluminum: The prices of aluminum in Wuxi and Nanhai increased, and the spot premium expanded. LME inventory remained unchanged, and SHFE inventory decreased. The social inventory of alumina decreased [4]. - Nickel: The price of Jinchuan nickel decreased, and the premiums of Jinchuan nickel and 1 imported nickel relative to Wuxi increased. LME inventory remained unchanged, and SHFE inventory decreased. The social inventory of nickel decreased [4]. - Zinc: The main settlement price remained unchanged, and the near - far month spread increased. The spot price remained unchanged, and the domestic and imported spot premiums decreased. LME inventory remained unchanged, and SHFE inventory increased. The social inventory decreased [5]. - Tin: The main settlement price decreased, and the LME price decreased. The near - far month spread increased, and the spot price decreased. LME inventory remained unchanged, and SHFE inventory increased [5]. 3.3 Chart Analysis - Spot Premium: Charts show the historical trends of spot premiums for copper, aluminum, nickel, zinc, lead, and tin from 2019 - 2025 [7][9][12]. - SHFE Near - Far Month Spread: Charts display the historical trends of the near - far month spreads for copper, aluminum, nickel, zinc, lead, and tin from 2020 - 2025 [15][18][21]. - LME Inventory: Charts present the historical trends of LME inventories for copper, aluminum, nickel, zinc, lead, and tin from 2019 - 2025 [24][26][28]. - SHFE Inventory: Charts show the historical trends of SHFE inventories for copper, aluminum, nickel, zinc, lead, and tin from 2019 - 2025 [31][33][35]. - Social Inventory: Charts display the historical trends of social inventories for copper, aluminum, nickel, zinc, stainless steel, and 300 - series from 2019 - 2025 [37][39][41]. - Smelting Profit: Charts show the historical trends of copper concentrate index, rough copper processing fee, aluminum smelting profit, nickel - iron smelting cost, zinc smelting profit, and stainless - steel 304 smelting profit rate from 2019 - 2025 [44][46][48]. 3.4 Non - Research Content - The report introduces the members of the non - ferrous metals team, including Zhan Dapeng, Wang Heng, and Zhu Xi, along with their educational backgrounds, positions, research directions, and professional qualifications [50][51][52].
