Report Industry Investment Ratings No specific industry investment ratings are provided in the reports. Core Views - **Domestic and Overseas Economy**: Domestically, pro - service consumption policies in September and real - estate policies are being promoted, but their effects need further observation. Industrial profit repair takes time. Overseas, the US economy shows "soft landing" features, and employment data strengthens the market's Fed rate - cut expectation. Attention should be paid to non - farm employment and unemployment data. Also, the high prices of long - term bonds in the UK, Germany, and France may lead to speculation about a global credit "crisis" [2]. - **Renminbi Exchange Rate**: The core of the current RMB - US dollar exchange rate is the rhythm control. External environment changes will dominate the short - term spot exchange rate. After a strong employment report followed by a weak QCEW correction notice, market dovish sentiment may increase. The non - farm data is crucial. The RMB - US dollar spot exchange rate is likely to gradually repair to a reasonable equilibrium, with attention on market sentiment around 7.13 [4]. - **Stock Index**: The stock index is expected to adjust in the short term, with limited downside space [4]. - **Treasury Bonds**: The bond market lacks upward momentum, and the 10 - year Treasury yield has resistance around 1.75%. The market may enter a short - term shock. It is not advisable to chase high, and previous long positions should stop profit [7]. - **Container Shipping**: The short - term weak and volatile pattern continues. There are uncertainties from US tariffs and mainstream shipping companies' Golden Week blank - sailing plans.

Report Industry Investment Ratings - There is no information about industry investment ratings in the provided reports. Core Views Copper - Copper pricing returns to macro trading. With the US economy weakening, the copper price faces upward pressure. However, from the Samuelson rule, the market has not entered a recession narrative, and the downside space is difficult to open. In the short term, the copper price lacks upward momentum and is expected to fluctuate within a range, with the main contract referring to 77,000 - 80,000 yuan/ton. The "tight mine supply + resilient demand" provides price support [1]. Aluminum - The alumina market is expected to maintain a slight surplus, with the main contract price expected to fluctuate widely between 3,000 - 3,400 yuan/ton. The aluminum price is expected to remain under pressure at high levels in the short term, with the main contract price referring to 20,000 - 21,000 yuan/ton. Key factors to monitor include inventory changes and marginal demand changes [5]. Aluminum Alloy - The supply - demand imbalance of aluminum alloy is expected to continue, with the market remaining in a narrow - range oscillation. The main contract is expected to trade between 19,200 - 20,200 yuan/ton. Key factors to watch are upstream scrap aluminum supply and import changes [7]. Zinc - The basic situation of "loose supply + weak demand" is insufficient to boost the continuous upward movement of the zinc price, but the low inventory provides price support. In the short term, the zinc price is expected to oscillate, with the main contract referring to 22,000 - 23,000 yuan/ton [10]. Tin - If the supply of tin ore recovers smoothly, a short - selling strategy is recommended; if the supply recovery falls short of expectations, the tin price is expected to continue to oscillate at a high level. Key factor to monitor is the import situation of Burmese tin ore [14]. Nickel - In the short term, the nickel price is expected to adjust within a range, with the main contract referring to 118,000 - 126,000 yuan/ton. The medium - term supply is expected to be loose, which restricts the upward space of the price. Key factor to watch is the change in macro expectations [16]. Stainless Steel - The stainless steel price is expected to oscillate in the short term, with the main contract operating between 12,600 - 13,200 yuan/ton. Key factors to monitor are policy trends and the supply - demand situation of nickel ore and nickel iron [17]. Lithium Carbonate - The market sentiment and news mainly drive the lithium carbonate price. The main contract price may test the range of 78,000 - 80,000 yuan/ton. However, attention should be paid to the fact that the current price has already reflected some of the results, and unilateral trading should be cautious [20].
