Report Industry Investment Ratings - Copper: ★☆☆ [1] - Aluminum: ★☆☆ [1] - Alumina: ななな [1] - Cast Aluminum Alloy: 文文文 [1] - Zinc and Stainless Steel: ☆☆☆ [1] - Tin: ★☆☆ [1] - Lithium Carbonate: ★☆☆ [1] - Industrial Silicon: ななな [1] - Polysilicon: な☆☆ [1] Core Views - The report provides daily analysis of various non - ferrous metals, including price trends, supply - demand situations, and investment suggestions for each metal [2][3][4] Summary by Metal Copper - On Friday, Shanghai copper prices increased, and the weekly K - line closed positive. The 2508 contract reduced positions rapidly. The spot copper price rose to 78,660 yuan, with the Shanghai premium expanding to 175 yuan and the Guangdong premium shrinking to 45 yuan. Technically, after last week's price adjustment, LME copper traded between the MA60 and MA40 moving averages. Traders are advised to hold short positions or try to sell call options with an exercise price of 80,000 yuan and buy put options with an exercise price of 76,000 yuan on the 2508 contract [2] Aluminum, Alumina, and Aluminum Alloy - Shanghai aluminum prices fluctuated, with the East China spot premium at 110 yuan. The social inventories of aluminum ingots and aluminum rods decreased by 0.9 million tons and 0.5 million tons respectively compared to Monday. Accumulation of inventories is still difficult. After the pre - demand, the decline in demand is not more than seasonal. Cast aluminum alloy follows the fluctuations of Shanghai aluminum. The Baotai quotation increased by 100 yuan to 19,500 yuan. The demand is weak, but the supply of scrap aluminum in the market is tight. The alumina spot price increase trend has eased but is still in a premium state. The domestic alumina operating capacity has returned to a historical high and is in an oversupply state [3] Zinc - Black prices continued to rebound, concerns about US tariffs eased, and the macro - sentiment improved. The import window remained closed, and the strong external market drove the domestic market up. However, downstream acceptance of high - priced zinc is low, and it is difficult for traders to sell. The supply is expected to increase, and the term structure of Shanghai zinc has flattened. Shanghai zinc is still considered to face pressure in the rebound, waiting for short - selling opportunities around 23,000 yuan/ton [4] Lead - Both domestic and foreign markets are accumulating inventories. The export of lead - acid batteries is affected by tariff issues again, and short - sellers increased positions. The weighted position of Shanghai lead increased to 104,000 lots, and the settled funds reached 1.569 billion yuan. Recycled lead is reluctant to sell at low prices, and the downstream's willingness to buy at low prices has improved. The cost - end support is still strong. Whether Shanghai lead can stop falling at 16,800 yuan/ton needs to be observed [6] Nickel and Stainless Steel - Shanghai nickel prices rebounded, and the market trading was active. The stainless - steel market is in the traditional off - season, and spot transactions are weak. The price support from the upstream has significantly weakened. The inventories of nickel iron, pure nickel, and stainless steel have all increased, but the overall inventory level is still high. Technically, Shanghai nickel still has room for rebound, waiting for a better short - selling position [7] Tin - Shanghai tin reduced positions and closed positive. The main contract changed quickly this month, and the 2509 contract has become the main position - holding contract. The spot tin price increased by 3,600 yuan to 265,500 yuan. Technically, it is recommended to use the MA60 moving average as the boundary between strength and weakness. Continue to pay attention to the change of the low inventory of 2,000 tons overseas. Hold previous high - position short positions [8] Lithium Carbonate - Lithium carbonate prices rebounded and reached a high level. The market trading was active. A series of shutdown news maintained market enthusiasm, but there was obvious selling pressure around 70,000 yuan. The total market inventory is high, and traders buy at low prices. The latest quotation of Australian ore is 705 US dollars, with a large rebound from the low level. There is a strong hedging demand for lithium carbonate futures prices in the range of 67,000 - 70,000 yuan. Short - sellers should use position dispersion to defend [9] Industrial Silicon - Industrial silicon futures prices slightly declined, while the spot price of Xinjiang 421 silicon continued to rise to 8,850 yuan/ton. The downstream polysilicon is expected to increase demand due to the resumption of production of leading enterprises, and the operating rate of silicone monomer plants has continued to rise. On the supply side, large factories have not resumed production after previous shutdowns, and the weekly output in Xinjiang has continued to decline slightly. The fundamentals are improving marginally, and the trend is expected to be oscillating and strengthening [10] Polysilicon - Polysilicon futures prices slightly declined. According to SMM, the expected increase in silicon wafer quotes and cost calculation result in a comprehensive price of 43,870 yuan/ton. The "weak reality" is mainly concentrated in the inventory level. With the resumption of production of some bases of leading enterprises, there may be a slight increase in inventory. Policy expectations are still the main trading logic, and the overall trend is mainly oscillating and strengthening [11]
