Key Information and Investment Strategy - Supply Side: Multiple domestic and foreign copper mines have production disruptions, leading to a negative China copper concentrate import index and a tight domestic copper concentrate supply - demand expectation. The expected increase in scrap copper supply has led to a rise in domestic crude copper or anode plate processing fees. Copper smelters' maintenance capacity in October increased month - on - month [1] - Demand Side: The shipping enthusiasm of domestic electrolytic copper spot traders has weakened, resulting in low downstream purchasing sentiment [1] - Inventory Side: China's electrolytic copper social inventory increased compared with last week; LME electrolytic copper inventory decreased compared with last week; COMEX copper inventory increased compared with last week [1] 7. Trading Strategy - It is recommended to mainly lay out long positions after the price drops. Pay attention to the support level around 80,000 - 83,000 and the resistance level around 86,000 - 89,000 for Shanghai copper. For London copper, pay attention to the support level around 9,500 - 10,200 and the resistance level around 11,000 - 12,000.
