1. Report Industry Investment Rating - Not mentioned in the provided content 2. Core Viewpoints of the Report - The report focuses on the weekly trends of non - ferrous metals, analyzing the price movements, supply - demand situations, and future outlooks of various metals such as copper, aluminum, zinc, etc. It suggests different trading strategies based on each metal's characteristics, like holding copper long - positions with certain stop - profit measures, being cautious about high - position risks in tin, etc. [1] 3. Summary According to Relevant Catalogs 3.1 Copper - **Price and Market**: Last week, both domestic and foreign copper prices hit record highs. The probability of the Fed cutting interest rates in February 2026 is high. The spot signal shows that the inflection point of copper price is not obvious. [1] - **Supply**: In December, there is a certain production rush expectation, with an estimated monthly output increase of 5.57 tons. Domestic smelters may choose to reduce the production of 106 primary copper concentrates during equipment shutdown. [1] - **Outlook**: The LME copper price is at a high level, and the spot premium has decreased. The market is mainly trading based on expectations. There is a probability that the upward trend of copper prices may pause. If the Fed cuts interest rates or the domestic spot premium weakens, the copper price at a record high may correct. Long - positions can be held along the M5 moving average, and partial active profit - taking can be considered. [1] 3.2 Aluminum and Alumina - **Supply**: The domestic alumina operating capacity remains at a historical high of 96 million tons, with no long - term production reduction. In December and January, 50,000 tons and 110,000 tons of exchange warehouse receipts will expire and flow out respectively. [1] - **Demand**: The downstream aluminum processing start - up rate decreased by 0.4 percentage points to 61.9% month - on - month. In November, China's exports of unwrought aluminum and aluminum products decreased by 14.8% year - on - year but increased by 66,800 tons month - on - month. [1] - **Inventory and Spot**: Aluminum ingot inventory decreased by 1000 tons to 985,000 tons, and aluminum bar social inventory decreased by 7000 tons to 121,000 tons. The inventory is higher than in previous years. Spot discounts in East, Central, and South China have widened. [1] - **Outlook**: Non - ferrous metals are still the focus of funds. The upward trend of silver and copper prices has driven up aluminum prices. The medium - term fluctuating and strengthening trend continues, but in the short term, market sentiment may fluctuate, and it is advisable to wait and see. [1] 3.3 Zinc - **Price and Market**: Last week, SHFE zinc rose 3.92% and strongly broke through the annual line, following the external market trend. The internal - external price difference is oscillating at a high level. [1] - **Supply**: LME zinc inventory increased to 55,400 tons. Overseas smelters' production resumption expectations are insufficient. The supply of zinc concentrates is tight, and domestic smelter maintenance is expanding. The zinc ingot export window is open, and downstream demand is stable. [1] - **Demand**: Southern consumption is good, while northern demand weakens with the cold weather. In the "15th Five - Year Plan", the expected investment in underground pipeline network construction and renovation is about 5 trillion, and galvanized pipe consumption is expected to be strong in 2026. [1] - **Outlook**: Supported by tight ore supply, SHFE zinc can be seen as a low - level rebound. After breaking through the annual line, it is expected to further test the 24,000 integer mark. [1] 3.4 Lead - **Price and Market**: Last week, the expectation of smelter production reduction and increased downstream bargain - hunting purchases supported the market rebound. The SHFE lead main contract rose 1.7%, and LME lead rebounded to the 20 - day moving average and then faced pressure. [1] - **Supply**: LME lead inventory decreased to 243,000 tons, still relatively high. The supply of lead concentrates is in short supply, and the recycling volume of waste batteries has decreased. The market supply of lead ingots is tight. [1] - **Demand**: The start - up rate of lead - acid battery production increased by 1.07 percentage points to 24.46% week - on - week. The consumer market has both positive and negative factors, with insufficient incremental expectations. [1] - **Outlook**: Constrained by cost and consumption, SHFE lead is expected to oscillate in the range of 17,000 - 17,300 yuan/ton. There may be short - term price increases due to capital movements. [1] 3.5 Nickel and Stainless Steel - **Price and Market**: SHFE nickel rebounded and traded sideways at a high level, with light market trading and relatively low positions. SHFE stainless steel also rebounded, but overall trading was sluggish. [1] - **Supply and Demand**: In the context of repeated macro - expectations, the willingness of both long and short sides to compete has decreased. Although stainless steel mills have frequently announced production cuts, the actual production reduction in November was insufficient. Downstream demand confidence is lacking. [1] - **Inventory**: Pure nickel inventory increased by 1500 tons to 57,000 tons, nickel iron inventory decreased by 1000 tons to 29,300 tons, and stainless steel inventory increased by 1000 tons to 997,000 tons. [1] - **Outlook**: Given high - level inventory and volatile macro - factors, short - selling at high levels is more reasonable. [1] 3.6 Tin - **Price and Market**: Funds have pushed up tin prices. LME tin reached a maximum of $41,000, and SHFE tin weighted price reached a maximum of 323,800 yuan. The short - term price fluctuations have increased. [1] - **Supply**: Indonesia's tin exports in November decreased. The situation in the Congo is uncertain. Domestic tin production may decline slightly in December. The real - world supply of tin ore is tight, and the cost of recycled materials is fluctuating. [1] - **Demand**: There are no bright spots in traditional fields, and the demand highlight is high - end semiconductor products. Domestic spot trading has deepened, and social inventory has increased. [1] - **Outlook**: In 2026, especially after the Spring Festival peak season, the probability of an increase in supply is high, and the recovery speed may be faster than demand. Attention should be paid to high - position risks. [1] 3.7 Lithium Carbonate - **Price and Market**: Last week, lithium carbonate futures adjusted, with active short - selling in the market. The spot price of battery - grade lithium carbonate has slightly corrected. [1] - **Supply and Demand**: The overall demand remains strong. In December, the sales volume of new energy vehicles is expected to perform well. The market is in a situation of both supply and demand. The overall inventory of downstream battery and material factories is flat or slightly reduced. [1] - **Inventory**: The total market inventory decreased by 2500 tons to 113,600 tons, smelter inventory decreased by 3600 tons to 21,000 tons, and downstream inventory increased by 1700 tons to 44,000 tons. [1] - **Outlook**: The price of lithium carbonate has fallen sharply from a high level, with large market differences. The fundamentals are generally strong, and the short - side is relatively tight. [1] 3.8 Industrial Silicon - **Price**: The main contract of industrial silicon S12601 showed a weak downward trend in the range of 8900 - 9030 yuan/ton this week. The price of 421 - grade industrial silicon in Xinjiang has dropped to 9000 yuan/ton. [1] - **Supply**: The total production of industrial silicon in December is expected to slightly decline to 396,000 tons, a month - on - month decrease of 31.8%. Some enterprises plan to slightly reduce the supply volume. [1] - **Inventory**: Social inventory increased by 800 tons to 558,000 tons, with an increase in both general and delivery warehouses. [1] - **Outlook**: The price of industrial silicon has fallen to the lower limit of the range. The inventory reduction at the end of the year is still under pressure. If the actual production reduction of local factories is limited, the price may further decline. [1] 3.9 Polysilicon - **Price**: Last week, the main contract of polysilicon reached a high of 59,200 yuan/ton due to the expectation of warehouse receipts. The expansion of delivery brands may suppress bullish sentiment. [1] - **Supply and Demand**: The output in November was 114,600 tons, lower than expected. In December, it is expected to slightly decline. Battery and silicon wafer enterprises have reduced production. [1] - **Inventory**: The inventory of polysilicon manufacturers increased by 10,000 tons week - on - week to 291,000 tons. [1] - **Outlook**: The fundamentals of polysilicon have significantly weakened, but the price may still be strong after a brief negative impact if the registered quantity of warehouse receipts is lower than expected.
