Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core Viewpoints of the Report - Copper: Overnight, both domestic and international copper prices fluctuated with an upward bias, and domestic spot imports remained in a loss. The US market was closed for Thanksgiving, reducing its guiding role. The Fed's Beige Book showed that the US economic activity has nearly stalled recently, the job market continues to weaken, and inflationary pressures persist, posing challenges to monetary policy. LME copper inventory increased by 675 tons to 157,175 tons, Comex copper inventory remained at 378,904 tons, SHFE copper warrants decreased by 3,952 tons to 35,873 tons, and BC copper decreased by 300 tons to 5,502 tons. The demand for copper showed a slow recovery as downstream acceptance improved despite high prices. The stabilization of domestic and international stock markets and a significant increase in the annual long - term copper contract price pushed up the copper price. However, the "inventory dam" will still limit the upside of copper prices this year. It is recommended to monitor the performance of copper prices at high levels, maintain the view of high - level fluctuations for now, but be aware that an effective upward breakthrough may lead to a new round of volatility increase and bullish sentiment [1]. - Aluminum: Overnight, alumina fluctuated with an upward bias, with AO2601 closing at 2,730 yuan/ton, a 0.55% increase, and open interest increasing by 3,459 lots to 359,000 lots. Shanghai aluminum fluctuated weakly, with AL2601 closing at 21,480 yuan/ton, a 0.28% decrease, and open interest increasing by 223 lots to 257,000 lots. Aluminum alloy also fluctuated weakly, with the main contract AD2601 closing at 20,715 yuan/ton, a 0.31% decrease, and open interest decreasing by 182 lots to 5,334 lots. In the spot market, the SMM alumina price dropped to 2,831 yuan/ton, the spot discount of aluminum ingots widened to 20 yuan/ton, and the Foshan A00 quotation rebounded to 21,380 yuan/ton, at a discount of 70 yuan/ton to the Wuxi A00 price. Aluminum rod processing fees remained stable in many places, while those in Xinjiang, Nanchang, and Wuxi decreased by 20 - 50 yuan/ton. The processing fees of 1A60 - series aluminum rods remained stable, and the processing fees of low - carbon aluminum rods in Yunnan increased by 75 yuan/ton. Environmental inspections have started in the north, mainly targeting the mining end. Some northern alumina plants have undergone phased maintenance, but there has been no large - scale production cut. The warehouse capacity in Xinjiang is approaching full, and the social inventory of alumina has been slightly relieved. Downstream raw material inventory backlogs continue to put pressure on prices. As the expectation of US interest rate cuts declines, the macro - sentiment has become more cautious. The decline in the aluminum price center and the temporary lifting of environmental production restrictions in Henan have led to the partial resumption of processing production lines, increasing the outbound volume of aluminum ingots. The initial tightness in Xinjiang's shipments and the limited decline in molten aluminum have helped the aluminum ingot inventory continue to decline slightly, providing short - term support for the aluminum price, but there is still an upper limit [1][2]. - Nickel: Overnight, LME nickel fell 0.03% to $14,840/ton, while Shanghai nickel rose 0.21% to 117,160 yuan/ton. LME nickel inventory increased by 930 tons to 255,450 tons, and SHFE warrants decreased by 396 tons to 33,548 tons. The LME 0 - 3 month spread remained negative, and the import nickel premium remained at 400 yuan/ton. The benchmark price of nickel ore decreased slightly, but the premium remained relatively stable. In the nickel - iron to stainless - steel industry chain, the transaction price center of nickel - iron has shifted downwards, weakening the raw material support. The weekly inventory of stainless steel has increased, and the market is sluggish. In the new energy industry chain, the tight supply of raw materials provides a bottom - support, but the production of ternary precursors in November decreased month - on - month. The inventory pressure of primary nickel is becoming more apparent. Considering the cost of producing electrowon nickel from SMM's integrated MHP at 110,000 yuan/ton as support, one may consider bottom - fishing and waiting for positive factors to materialize, but be vigilant against macro - disturbances, potential production cuts of primary nickel, and overseas industrial policy adjustments [2].
