印尼铜矿26年产量指引下调，铜价领涨基本金属

1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The basic metals are expected to maintain an oscillatory upward pattern in the short - to - medium term, supported by a weak US dollar and supply disruptions, while the weak terminal demand will limit the upside. In the long term, potential domestic stimulus policies and supply disruptions in copper, aluminum, and tin support the prices of basic metals. Opportunities for low - buying and long - holding in copper, aluminum, and tin are recommended [1]. 3. Summary by Related Catalogs 3.1行情观点 - Copper: Grasberg copper mine has a large production cut, and copper prices are operating strongly. The reduction in Grasberg's production intensifies the supply shortage, and with the Fed's interest rate cut and the approaching peak demand season, if copper inventories continue to decline, copper prices may remain strong [7][8]. - Alumina: Affected by anti - involution sentiment, alumina prices have a slight rebound. The fundamentals show an over - supply situation, but the limited decline in ore prices restricts the downside. It is expected to maintain a low - level oscillatory pattern in the short term [9][10]. - Aluminum: Attention should be paid to the demand quality, and aluminum prices are oscillating. After the interest rate cut, the supply is increasing with new capacity, and the demand is expected to improve, but the inventory accumulation continues. The price is expected to oscillate in the short term and may rise in the medium term [11][12]. - Aluminum Alloy: Cost support remains, and the market is oscillating. The cost reduction space is limited, the supply and demand are marginally improving, and short - term price oscillation is expected. There are opportunities for cross - variety arbitrage [13][16]. - Zinc: The expectation of supply - demand surplus is still strong, and zinc prices are weak. Macro factors support the non - ferrous sector, but the supply is increasing and the demand is average. Zinc prices may oscillate in the short term and decline in the long term [16][17]. - Lead: The supply of recycled lead is decreasing, and lead prices are oscillating strongly. With the approaching of the National Day, downstream enterprises are stocking up, while the supply of recycled lead is tight. The price is expected to oscillate strongly before the holiday [18][20]. - Nickel: LME nickel inventory has exceeded 230,000 tons, and nickel prices are oscillating widely. The market sentiment dominates the price, and the industrial fundamentals are weakening. Short - term wide - range oscillation is expected [21][23]. - Stainless Steel: Warehouse receipts are continuously decreasing, and stainless steel prices are oscillating. The prices of nickel and chromium are stable, and the supply is increasing. Attention should be paid to the demand during the peak season and the inventory change [26]. - Tin: Supply constraints still exist, and tin prices are oscillating. The supply is tight, but the terminal demand is weakening. The price is expected to oscillate with strong bottom support [27][28]. 3.2行情监测 - Not provided with specific monitoring content in the given text
