Report Industry Investment Ratings - Copper: ★☆☆ (indicating a bullish bias, with a driving force for price increase but limited operability on the trading floor) [1] - Aluminum: ★★★ (suggesting a clearer bullish trend and relatively appropriate investment opportunities) [1] - Alumina: ★★★ [1] - Cast Aluminum Alloy: ★★★ [1] - Zinc: ★★★ [1] - Nickel and Stainless Steel: ★☆☆ [1] - Tin: ★★★ [1] - Lithium Carbonate: ★★★ [1] - Industrial Silicon: ★★★ [1] - Polysilicon: ★★★ [1] Core Views - The overall market shows a complex situation with different trends for each metal. Some metals are supported by supply - demand factors, while others are affected by cost, inventory, and market sentiment [2][3][4] - For most metals, there are specific price trends and trading suggestions based on their individual fundamentals and market conditions Summary by Metals Copper - On Wednesday, SHFE copper increased in positions, fluctuated, and closed up. The spot copper was reported at 88,980 yuan, with a premium in Shanghai of 140 yuan and a shrinking premium in Guangdong to 85 yuan. It has resilience in the previous trading - intensive area of 88,300 - 88,500 yuan. Long positions should be held based on the MA5 daily moving average [2] Aluminum, Alumina, and Aluminum Alloy - The fundamentals of SHFE aluminum have limited contradictions. The social inventory of aluminum ingots in major areas has shown narrow fluctuations this week. It is testing the resistance near the previous high of 22,000 yuan. The price difference between cast aluminum alloy and SHFE aluminum has expanded to over 800 yuan, with potential for narrowing at the end of the year [3] - Alumina has a high operating capacity, with increasing industry inventory and exchange warehouse receipts. The supply - surplus pattern remains unchanged, and it will be weak until large - scale production cuts occur [3] Zinc - Domestic smelters have a strong production - reduction expectation, and overseas smelters have a mediocre production - increase expectation in the fourth quarter. The supply constraint of zinc ingots is strengthening, and the zinc price is expected to rise, possibly breaking through the annual line [4] Nickel and Stainless Steel - SHFE nickel's rebound is under pressure, and it is mainly in a low - volatility, range - bound operation. The inventory of stainless steel 300 - series cold - rolled products has increased, and the support from the rebound of upstream prices is weakening [7] Tin - SHFE tin increased in positions and rose again. It is not recommended to chase the high price, and a medium - to - long - term short - position with a hedging strategy is advisable [8] Lithium Carbonate - The price of lithium carbonate fluctuates narrowly. The market has a large divergence. The total market inventory has decreased, and the price of Australian ore remains strong [9] Industrial Silicon - The industrial silicon market is in a weakening trend. The supply in the main production areas of Sichuan and Yunnan may decrease during the dry season, and the demand may be suppressed by the joint production cuts of silicone enterprises, but the price decline is expected to be limited [10] Polysilicon - Polysilicon strengthened again today after a callback due to position limits yesterday. The main driver is the expectation of tight delivery products. In the short term, the market is likely to fluctuate due to potential regulatory rules and national meetings [11]
