国庆长假临近，节前多头减仓控风险为宜

1. Report Industry Investment Rating Not provided in the content 2. Core Viewpoints of the Report - With the National Day holiday approaching, it is advisable for long - position holders to reduce positions to control risks. In the short - to - medium term, weak US dollar and supply disruptions support metal prices, while weak terminal demand limits the upside. In the long term, potential domestic stimulus policies and supply disruptions in copper, aluminum, and tin support basic metal prices. The report maintains the view of buying copper, aluminum, and tin on dips but suggests reducing long positions or taking profits due to the approaching holiday [1]. - Copper: The reduction in Indonesian copper mine production has a significant impact, and copper prices are expected to oscillate strongly. Aluminum oxide: The fundamentals remain weak, and the upside of aluminum oxide prices is under pressure. Aluminum: Inventories have decreased, and aluminum prices will oscillate. Aluminum alloy: Cost support remains, and the market will oscillate. Zinc: The decline in ferrous product prices causes zinc prices to oscillate weakly. Lead: Pre - holiday stocking has weakened, and lead prices are under pressure. Nickel: LME nickel inventories continue to increase, and nickel prices will oscillate widely. Stainless steel: The slight decline in ferronickel prices leads to a correction in the stainless - steel market. Tin: Supply disruptions in Indonesia reappear, and tin prices will oscillate [2]. 3. Summary According to Relevant Catalogs 3.1行情观点 Copper - Viewpoint: The reduction in Indonesian copper mine production has a significant impact, and copper prices are expected to oscillate strongly. - Analysis: Grasberg mine in Indonesia may see a 35% drop in 2026 production. The Fed cut interest rates by 25bp in September 2025. In August, SMM China's electrolytic copper production decreased by 0.28 tons month - on - month and increased by 15.59% year - on - year. As of September 29, copper inventories increased by 0.82 tons to 14.83 tons. After the release of "770 - document", there was a large - scale shutdown and production reduction in the recycled copper market [7][8]. - Logic: The Fed's interest - rate cut supports copper prices. The supply of copper mines is disrupted, and the cost of scrap copper recycling has increased, leading to expected production cuts in electrolytic copper. Terminal demand is in the peak season, and downstream stocking willingness has increased. If inventories continue to decline, copper prices may remain strong [9]. - Outlook: Copper supply constraints remain, and with increased supply disruptions and a low - level US dollar index, copper is expected to oscillate strongly [9]. Aluminum Oxide - Viewpoint: The fundamentals remain weak, and the upside of aluminum oxide prices is under pressure. - Analysis: On September 29, the prices of aluminum oxide in various regions declined. An electrolytic aluminum plant in Xinjiang tendered for 10,000 tons of aluminum oxide, with the winning bid price down 10 - 20 yuan/ton compared to the previous period. Aluminum oxide warehouse receipts increased by 10,548 tons to 159,759 tons [10][11]. - Logic: Macro - sentiment affects the market. The operating capacity remains high, and the strong inventory - accumulation trend continues. The fundamentals are weak, but the decline in ore prices in the fourth quarter is limited, which may restrict the downside. Potential production - cut expectations and Guinea - related disruptions will affect prices [11]. - Outlook: Aluminum oxide is expected to oscillate in the short term. It is recommended to wait and observe or conduct short - term trading before the holiday [11]. Aluminum - Viewpoint: Inventories have decreased, and aluminum prices will oscillate. - Analysis: On September 29, the average price of SMM AOO aluminum decreased by 80 yuan/ton. Domestic mainstream consumption - area electrolytic aluminum inventories decreased by 2.5 tons compared to last Thursday and 4.6 tons compared to last Monday. Aluminum rod inventories also decreased. The State Council's eight - department document promotes the stable growth of the non - ferrous industry [11][12]. - Logic: The Fed's interest - rate cut makes the US dollar weak. Supply capacity is increasing, and demand is expected to improve as the peak season approaches. Pre - holiday stocking drives inventory reduction, and the spot is at a discount. Aluminum prices are expected to oscillate [12]. - Outlook: In the short term, consumption and inventory - reduction sustainability need to be observed. In the medium term, with limited supply growth and resilient demand, the center of aluminum prices is expected to rise [12]. Aluminum Alloy - Viewpoint: Cost support remains, and the market will oscillate. - Analysis: On September 29, the price of Baotai ADC12 remained unchanged. The average price of SMM AOO aluminum decreased by 80 yuan/ton. The EU may impose a 30% tax on scrap metal exports. In August 2025, the import volume of unwrought aluminum alloy decreased by 16.7% year - on - year [13]. - Logic: The supply of scrap aluminum is tight, and cost reduction space is limited. Supply - side production is increasing, and demand is marginally improving. Inventories are accumulating, and prices are expected to oscillate. There are opportunities for cross - variety arbitrage [15]. - Outlook: In the short term, there are opportunities for cross - variety arbitrage. In the medium term, supply and demand are weak, but raw - material disruptions are possible, and prices are expected to oscillate within a range [15]. Zinc - Viewpoint: The decline in ferrous product prices causes zinc prices to oscillate weakly. - Analysis: On September 29, the spot price of zinc in different regions was at a discount to the main contract. As of September 29, SMM's seven - region zinc ingot inventories decreased by 0.90 tons. CZSPT set the import zinc concentrate processing fee for the end of Q4 2025 at 120 - 140 US dollars/dry ton [15][16]. - Logic: The macro - environment is slightly negative. Zinc ore supply is loosening, and smelters' profitability is good. Domestic consumption is in the transition period between peak and off - peak seasons, and demand is average. Fundamentals are in surplus, but the Fed's interest - rate cut expectation makes the non - ferrous sector strong, and zinc prices may oscillate at a high level in the short term and decline in the long term [16]. - Outlook: Zinc ingot production will remain high in September, and inventories may accumulate. Zinc prices are expected to oscillate [17]. Lead - Viewpoint: Pre - holiday stocking has weakened, and lead prices are under pressure. - Analysis: On September 29, the price of waste electric vehicle batteries increased by 25 yuan/ton, and the price of SMM 1 lead ingot decreased by 125 yuan/ton. Social inventories of lead ingots decreased by 0.43 tons. After pre - holiday stocking, there may be new low - price stocking intentions, but there is a risk of inventory accumulation after the holiday [17]. - Logic: Spot premiums are narrowing, and the price difference between primary and recycled lead is decreasing. The cost of recycled lead smelting is rising, and production is increasing. Demand is in the transition period, and the lead - acid battery industry's operating rate is high. - Outlook: After the Fed's interest - rate cut, the US dollar rebounded slightly. Pre - holiday battery factory stocking is almost over, and demand may decline. Supply may increase, and costs are rising slightly. Lead prices are expected to oscillate [21]. Nickel - Viewpoint: LME nickel inventories continue to increase, and nickel prices will oscillate widely. - Analysis: On September 29, LME nickel inventories increased by 1188 tons to 231,312 tons. High - nickel pig iron prices are under pressure. A battery recycling company in Germany will build a large - scale lithium - battery recycling plant [21][22]. - Logic: Market sentiment dominates the market. The industrial fundamentals are weakening marginally. Nickel salt prices are slightly weakening, and inventories are accumulating. Short - term trading is recommended, and the performance of the ore end and macro - sentiment should be observed [23]. - Outlook: In the short term, the non - ferrous sector is strong, but LME nickel inventories are increasing significantly. Nickel prices may strengthen in the short term, and a wait - and - see approach is recommended in the long term [23]. Stainless Steel - Viewpoint: The slight decline in ferronickel prices leads to a correction in the stainless - steel market. - Analysis: As of September 29, stainless - steel futures warehouse receipts decreased by 357 tons. The average price of SMM 10 - 12% high - nickel pig iron decreased by 0.5 yuan/nickel point [25]. - Logic: Ferronickel and ferrochrome prices are stable. Stainless - steel production increased in August. Social inventories increased slightly, and warehouse receipts decreased. The structural over - supply pressure has eased. - Outlook: There is a risk of increased production cuts by steel mills. The fundamentals suppress prices. Attention should be paid to the peak - season demand and inventory and cost changes. Stainless - steel prices are expected to oscillate within a range in the short term [25]. Tin - Viewpoint: Supply disruptions in Indonesia reappear, and tin prices will oscillate. - Analysis: On September 29, LME tin warehouse receipts decreased by 105 tons to 2670 tons, and Shanghai tin warehouse receipts decreased by 127 tons to 5950 tons. The average price of Shanghai Non - ferrous Metals Network 1 tin ingot decreased by 2300 yuan/ton [25]. - Logic: The supply of tin is the core concern. The resumption of production in Wabang's Manxiang mining area is slow, and African tin production is unstable. Tin concentrate processing fees are low, and the operating rate of refined tin is low. Supply is tight, but terminal demand is weakening in the second half of the year, and inventory reduction is difficult in Q4. - Outlook: With tight supply at the mine end, tin prices have bottom support and are expected to oscillate [26]. 3.2行情监测 Not provided in the content 3.3中信期货商品指数 - On September 29, 2025, the comprehensive index of commodities was 2235.10, down 0.13%; the commodity 20 index was 2510.22, down 0.08%; the industrial products index was 2238.46, down 0.50%.
