Group 1: Research Views Copper - Overnight, both domestic and international copper prices fluctuated weakly and failed to continue the upward trend. The domestic spot copper imports were in a loss state. The US economic data showed resilience and inflation persistence. The labor - market slowdown concerns were alleviated. The LME copper inventory decreased by 350 tons to 144,425 tons, Comex inventory increased by 2,564 tons to 291,260 tons, and the domestic copper social inventory decreased by 0.44 million tons to 14.01 million tons. The Freeport McMoRan Indonesia Grasberg mine accident will impact global copper supply in Q4 and 2026. Although investors were cautious due to the cryptocurrency fluctuations and domestic holiday uncertainties, the supply reduction in Q4 will strongly support copper prices, and the quarterly average price is expected to rise. It is recommended to go long on dips and pay attention to Comex - LME copper and internal - external price spreads [1]. Aluminum - Alumina fluctuated weakly with AO2601 closing at 2919 yuan/ton, a 0.27% decline.沪铝 (AL2510) fluctuated strongly, closing at 20,800 yuan/ton, a 0.1% increase. Aluminum alloy fluctuated weakly. The SMM alumina price dropped to 3000 yuan/ton, and the aluminum ingot spot remained at par. The domestic bauxite mines have not resumed production, and the ore inventory is declining. Alumina is generally bearish but has basically bottomed out. The aluminum ingot has not reached the actual de - stocking inflection point. With the approaching of the double festivals, the downstream is in the stocking stage, but the current outbound volume is at the lowest level in the past three years, and the downstream purchasing willingness has declined, which restricts the upward momentum of aluminum prices [1][2]. Nickel - Overnight, LME nickel fell 1.26% to $15,240/ton, and Shanghai nickel fell 0.86% to 121,680 yuan/ton. The LME nickel inventory remained at 230,586 tons, and the domestic SHFE nickel warrants increased by 134 tons to 25,105 tons. The stainless - steel weekly inventory continued to decline, with the national mainstream market stainless - steel 89 - warehouse social inventory at 984,500 tons, a 0.26% week - on - week decrease. The cost of ferronickel has strengthened, but the supply has increased. In the new - energy sector, the ternary demand in September weakened slightly month - on - month, but the cobalt policy may lead to a relatively tight supply of MHP. The nickel price may rise slightly at the bottom, but inventory is a resistance to the price increase [2].
