1. Report Industry Investment Rating No relevant information provided. 2. Report Core Views Copper - Short - term trading focuses on interest - rate cut expectations. US inflation data shows potential upward pressure, but it may not prevent a restart of rate cuts. Trump has extended the China - US tariff truce for 90 days. - Fundamentally, it's approaching the traditional peak season. Spot premiums are strong, and domestic social inventories are decreasing. "Tight mine supply + resilient demand" supports copper prices. - In the future, copper pricing will return to macro trading. Weak economic expectations will cap copper prices, but the market is not in a recession narrative, so the downside is limited. It will likely fluctuate in the range of 78,000 - 79,500, depending on US economic data [1]. Aluminum - The aluminum market is under pressure with prices falling. The supply of alumina is expected to increase in the medium - term, and the market will be slightly oversupplied. - For electrolytic aluminum, the domestic production capacity is stable, but demand is weak. Under the pressure of inventory accumulation, demand weakness, and macro - level disturbances, the price is expected to be under pressure in the short - term, with the main contract price ranging from 20,000 - 21,000 [3]. Aluminum Alloy - The aluminum alloy market followed the decline of aluminum prices. The supply of scrap aluminum is tight, and demand is affected by the off - season. The market will remain in a situation of weak supply and demand, with the main contract price ranging from 19,600 - 20,400 [6]. Zinc - Overseas zinc mines are in an up - cycle of production and restart, but the growth rate of mine production is lower than expected. The supply of zinc concentrate is gradually being transmitted to the smelting end, and production has increased significantly. - Demand is in the seasonal off - season, and the primary processing industries' operating rates are at seasonal lows. Low inventory provides price support. In the future, the current fundamentals are not sufficient to boost a continuous rise in zinc prices, and it will likely fluctuate in the range of 22,000 - 23,000 [9]. Tin - Tin ore supply remains tight, and the actual output from Myanmar may be postponed to the fourth quarter. Demand is weak after the end of the photovoltaic installation rush and due to the off - season in the electronics industry. - Affected by the US PPI data, the market expects a delay in interest - rate cuts, and the dollar is strengthening, suppressing tin prices. If supply recovers smoothly, a short - selling strategy is recommended; otherwise, the price will likely remain high and fluctuate [11]. Nickel - The macro - level shows easing inflation pressure and a weak employment market, increasing expectations of more aggressive monetary easing. - The supply of nickel ore is expected to be loose, and the price of nickel iron has increased but still faces over - supply pressure. Stainless steel demand is weak, and the acceptance of high - priced nickel sulfate in the new energy sector is low. - Overseas inventory is high, and domestic inventory has increased. The price is expected to adjust in the range of 118,000 - 126,000 in the short - term [12]. Stainless Steel - The stainless - steel market is in the transition from the off - season to the peak season, with cautious downstream procurement. The export pressure has eased, and the macro - level expectation has strengthened. - The price of nickel iron is rising steadily, and steel mills' profits have improved, increasing production motivation. However, terminal demand is weak, and inventory reduction is slow. The price will likely fluctuate strongly in the range of 12,800 - 13,500 [14]. Lithium Carbonate - The lithium carbonate futures market is strong. There are supply - side uncertainties, and the fundamentals are in a tight balance. - Demand is expected to increase as it approaches the peak season, but the actual demand has not been significantly boosted due to inventory pressure in the material industry chain. - The price is expected to remain strong in the short - term, ranging from 86,000 - 92,000. A cautious and wait - and - see approach is recommended, and light - position long - entry on dips can be considered [17]. 3.

Report Industry Investment Rating - No relevant content provided. Core Viewpoints - As the Politburo meeting concludes and the sentiment related to "anti - involution" cools down, the market sentiment becomes rational, and the futures price trend weakens. If the subsequent demand cannot be effectively repaired, the steel price may not maintain the current level, and the futures price may gradually return to the supply - demand logic. It is recommended to continuously monitor the recovery progress of terminal actual demand and the support of the cost side for the finished product price [3]. - In the short term, the iron ore price may be slightly adjusted. Attention should be paid to whether the contradiction between high hot metal production and terminal demand will further intensify. Also, follow - up actions of blast furnace enterprises regarding the production suspension of Tangshan independent rolling enterprises need to be monitored [6]. - In the short - term market environment controlled by emotions, it is not recommended for speculative funds to participate excessively, and it is advisable to wait and see. Hedging funds can seize hedging opportunities according to their own situations but should control margin (cash flow) safety [10]. - It is expected that the industrial silicon price will fluctuate weakly, with support at 8000 yuan/ton. The polysilicon price is expected to fluctuate widely, with support levels at 47000 and 44000 yuan/ton respectively [14][16]. - In the short term, it is expected that glass and soda ash will fluctuate. In the long term, glass prices will fluctuate with macro - sentiment, and soda ash prices are expected to gradually increase in the price center, but their upward space is limited [18][19].
