1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report - Copper: Last week, Shanghai copper increased in volume and price, mainly due to the rising expectation of the Fed's interest rate cut and the weakening of the US dollar index. On Friday night, copper prices continued to rise, with LME copper breaking through the $11,000 mark and hitting a new high, while Shanghai copper approached the 89,000 mark. Technically, the open interest of Shanghai copper increased from 510,000 contracts to 560,000 contracts last week, showing strong short - term upward momentum. Attention should be paid to the technical pressure at the end - October high. If it breaks through, it may maintain a strong trend in the short term [6][63]. - Aluminum: Last week, aluminum prices rebounded with a decrease in positions, and there was a trend of increasing positions and rising prices on Friday night. This rebound was mainly driven by macro factors, such as the rising expectation of the Fed's interest rate cut. The decline in the Shanghai - LME ratio indicated that the rise was mainly led by the external market. Globally, the low inventory of electrolytic aluminum supported the price. However, as aluminum prices rebounded, domestic downstream demand decreased, and the spot discount widened. Technically, attention can be paid to the pressure at the 22,000 mark [7][63]. 3. Summary by Directory 3.1 Macro Factors - Last week, the market's expectation of the Fed's interest rate cut continued to rise, with the probability of a December rate cut increasing from 70% to nearly 90%. Correspondingly, the US dollar index weakened from the 100 mark, which was beneficial to non - ferrous metals and precious metals [11]. 3.2 Copper 3.2.1 Quantity - Price Trend - Last week, Shanghai copper increased in volume and price. On Friday night, copper prices continued to rise, with LME copper breaking through the $11,000 mark and Shanghai copper approaching the 89,000 mark. The open interest of Shanghai copper increased from 510,000 contracts to 560,000 contracts, indicating increased capital attention and strong short - term upward momentum [6][63]. 3.2.2 Copper Ore Shortage - Last week, the port inventory of copper ore continued to rise from a low level and was close to the same - period level in previous years. On November 28, Mysteel's port inventory of copper ore was 674,000 tons, an increase of 78,000 tons from the previous week. In November, with the rise in sulfuric acid prices, the upstream smelting profit also rebounded [25]. 3.2.3 Electrolytic Copper Stockpiling - On November 27, Mysteel's social inventory of electrolytic copper was 171,600 tons, a weekly decrease of 20,500 tons, while the inventory in COMEX + LME was 574,800 tons, a weekly increase of 18,400 tons [27]. 3.2.4 Downstream Primary Sector - As copper prices rose, the downstream market showed a situation of "not prosperous in the peak season", and the copper product start - up rate declined month - on - month in October. In November, the overall downstream entered the off - season, and copper prices remained high. It is expected that the downstream capacity utilization rate will remain at a low level in November [29]. 3.3 Aluminum 3.3.1 Quantity - Price Trend - Last week, aluminum prices rebounded with a decrease in positions, and there was a trend of increasing positions and rising prices on Friday night. The decline in the Shanghai - LME ratio indicated that the rise was mainly led by the external market.

Last week, alumina was weak, with the main contract price falling below the 2700 mark, while aluminum prices rose with the non - ferrous metal sector, and the profit of upstream electrolytic aluminum widened [45][47]. 3.3.3 Slowing Depletion of Electrolytic Aluminum - In November, as aluminum prices continued to rise, overseas electrolytic aluminum showed a stockpiling trend, and the depletion of domestic electrolytic aluminum social inventory slowed down. On November 27, Mysteel's social inventory of electrolytic aluminum was 590,000 tons, a decrease of 14,000 tons from the previous week, and the overseas electrolytic aluminum inventory was 544,700 tons, a decrease of 28,000 tons from the previous week [50]. 3.3.4 Downstream Primary Sector - Last week, the processing fee of aluminum rods generally declined from a high level, mainly due to the rebound of aluminum prices, which led to a decrease in downstream demand. The inventory of aluminum rods remained at a low level, with the in - factory inventory at 91,400 tons, a slight increase of 2,900 tons from the previous week [56][59].
