1. Report Industry Investment Ratings - Copper: Oscillating [6] - Alumina: Oscillating weakly [7] - Aluminum: Oscillating [10] - Aluminum Alloy: Oscillating at a high level [11] - Zinc: Oscillating weakly [13] - Lead: Oscillating [14] - Nickel: Oscillating strongly [16] - Stainless Steel: Oscillating [22] - Tin: Oscillating [23] 2. Core Views of the Report - The weak US dollar and the fermentation of reverse invoicing issues have pushed non - ferrous metals back to the upper edge of the recent range. In the short - to - medium term, the weak US dollar and supply disturbances support prices, while weak terminal demand expectations limit the upside. In the long term, potential incremental stimulus policies in China and supply disturbances in copper, aluminum, and tin support non - ferrous metal prices [1]. - Different non - ferrous metal varieties have different price trends and influencing factors. For example, copper prices are supported by macro factors and supply disturbances; alumina prices are under pressure due to over - supply; aluminum prices are affected by supply, demand, and inventory; and so on [6][7][10]. 3. Summary by Related Catalogs Copper - Information Analysis: The Fed's potential September rate - cut and the resilience of the US economy boost copper prices. In August, China's electrolytic copper production decreased slightly year - on - year. The spot price showed a premium, and the inventory increased. The processing fees of copper ore and blister copper are low, and the raw material supply is tight. The cost and difficulty of scrap copper recycling have increased, and some smelters may reduce production [6]. - Main Logic: Macro factors and supply disturbances support copper prices. The downstream demand was in the off - season, and the inventory accumulation was not obvious. Low inventory supports copper prices in the short term [6]. - Outlook: Copper supply constraints remain, and the inventory is low. However, the US copper tariff is not conducive to the Shanghai copper price. Copper is expected to oscillate [7]. Alumina - Information Analysis: On September 1, the spot price of alumina in most regions was stable, while that in Xinjiang decreased. Some alumina enterprises in Shanxi reduced production due to ore shortages. The winning bid price of a tender in Xinjiang decreased, and the railway freight in Shandong changed. The alumina warehouse receipts increased [7][8]. - Main Logic: The high - profit margin of smelters has shrunk, but the raw materials are relatively abundant. The operating capacity is at a high level, and the supply is in excess. The warehouse receipts and inbound volume have increased, and the price is expected to be under pressure. However, short - term supply capacity fluctuations and medium - to - long - term mine disturbances need attention [8]. - Outlook: The price is expected to oscillate weakly. Consider short - selling on rallies and pay attention to reverse arbitrage opportunities [10]. Aluminum - Information Analysis: On September 1, the average price of SMM AOO aluminum decreased, and the inventory of electrolytic aluminum ingots and aluminum rods increased. The warehouse receipts of electrolytic aluminum on the SHFE decreased. An Indonesian Chinese - funded electrolytic aluminum enterprise plans to put into production. The performance of some listed aluminum companies was released [10][11]. - Main Logic: The short - term US rate - cut expectation increases, and the US dollar is weak. The supply capacity is increasing, and the demand is expected to improve, but the terminal consumption is not strong. The inventory is accumulating, and the spot discount is widening. The aluminum price is expected to oscillate [11]. - Outlook: Observe the short - term consumption and inventory accumulation. The price is expected to oscillate within a range [11]. Aluminum Alloy - Information Analysis: On September 1, the price of Baotai ADC12 was stable, and the price difference between Baotai ADC12 and AOO aluminum changed. The SHFE adjusted the margin and price limit of cast aluminum alloy futures. The performance of some listed companies was released [11][12]. - Main Logic: The cost is supported by scrap aluminum. The supply decreased during the off - season, and some recycling plants reduced production due to policy changes. The downstream demand is mainly for rigid procurement. The inventory is accumulating, and the price is expected to oscillate. Pay attention to cross - variety arbitrage opportunities [12][13]. - Outlook: In the short term, ADC12 and ADC12 - A00 are oscillating at a low level. There is room for an increase in the future, and cross - variety arbitrage can be considered [13]. Zinc - Information Analysis: On September 1, the spot price of zinc showed a discount. The inventory of zinc ingots increased. A smelter in Guangxi plans to stop production for maintenance due to raw material supply interruption [13]. - Main Logic: The macro environment is slightly negative. The short - term zinc ore supply is loose, and the smelter's profitability is good. The domestic consumption is in the off - season, and the demand is weak. The zinc price is expected to oscillate at a high level in the short term and decline in the medium - to - long term [14]. - Outlook: In September, the zinc ingot production will remain high, and the demand recovery is limited. The inventory may continue to accumulate. The zinc price is expected to oscillate weakly [14]. Lead - Information Analysis: On September 1, the price of waste electric vehicle batteries and the price difference between primary and secondary lead were stable. The spot price of lead ingots was stable, and the warehouse receipts decreased. The traditional peak season of the lead - acid battery market was average, and the transportation was restricted in some regions, affecting the inventory [14][15]. - Main Logic: The spot discount and the price difference between primary and secondary lead are stable. The supply of lead decreased slightly, and the demand is in the transition period between the off - season and peak season. The demand for lead ingots is stable [15][16]. - Outlook: The macro environment is positive. The supply may tighten slightly this week, and the demand is stable. However, the release of accumulated lead ingots after the end of transportation restrictions may put pressure on the price. The lead price is expected to oscillate [16]. Nickel - Information Analysis: On September 1, the LME nickel inventory increased, and the SHFE nickel warehouse receipts decreased. Some nickel - related projects and policy changes were reported, such as a new nickel and copper refinery in Tanzania and the change of RKAB approval in Indonesia [16][17][18]. - Main Logic: The market sentiment dominates the market. The industrial fundamentals are weakening marginally. The ore supply may be loose after the rainy season. The production of intermediate products has recovered, and the nickel salt price has declined slightly. The inventory is accumulating, and the price is expected to oscillate. Use a short - term trading strategy [21]. - Outlook: The equity market is strong, and the expected RKAB approval in Indonesia in mid - September will make the nickel price oscillate strongly in the short term. Take a wait - and - see attitude in the long term [21]. Stainless Steel - Information Analysis: The stainless steel futures warehouse receipts decreased. The spot price showed a premium. The production and logistics in the nickel industry chain in Indonesia were not affected by the demonstrations [22]. - Main Logic: The prices of nickel iron and chromium iron are stable. The stainless steel production increased in August. Pay attention to the demand during the peak season. The inventory decreased slightly, and the structural over - supply pressure has eased [22]. - Outlook: Be wary of the possible expansion of production cuts by steel mills. The price is expected to oscillate in the short term. Pay attention to inventory and cost changes [22]. Tin - Information Analysis: On September 1, the LME tin warehouse receipts increased, and the SHFE tin warehouse receipts decreased. The spot price of tin decreased. The supply of tin ore is tight [23]. - Main Logic: The resumption of production in Wa State does not change the tight supply of tin ore in China. The export of refined tin in Indonesia decreased, and the production and export in Africa are unstable. The supply is tight, supporting the tin price. The terminal demand has weakened, and the inventory reduction is difficult [23]. - Outlook: The tin price is supported by the tight supply of ore. It is expected to oscillate, and the volatility may increase in August [23].
