1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Copper: Overnight, LME copper had a narrow - range oscillation, while SHFE copper trended weakly. US inflation expectations in August were relatively stable, but consumer confidence in re - employment prospects reached a historical low. LME copper inventory decreased by 2,125 tons to 148,150 tons, and domestic refined copper social inventory increased by 0.62 million tons to 14.69 million tons. With the approaching peak season, high copper prices led to weak downstream procurement. The poor US employment data restarted the market's expectation of Fed rate cuts and increased concerns about a US recession, affecting the sentiment of the non - ferrous market [1]. - Aluminum: Alumina trended weakly, with AO2601 closing at 2,955 yuan/ton, a 0.34% decline.沪铝 trended strongly, with AL2510 closing at 20,725 yuan/ton, a 0.07% increase. The aluminum alloy also trended strongly. Although there was a short - term improvement in sentiment due to environmental protection - related roasting restrictions in Shanxi and Henan, it was difficult to reverse the oversupply situation. With the increase in imports, the downward support for alumina was weak. The overall aluminum price trended strongly, and the termination of the recycled aluminum tax rebate restricted supply, making the aluminum alloy more resilient than electrolytic aluminum in the short term [1][2]. - Nickel: Overnight, LME nickel fell 0.65% to 15,180 US dollars/ton, and SHFE nickel fell 0.53% to 120,860 yuan/ton.

The weekly inventory of stainless steel decreased slightly, but supply increased. With the rise in raw material prices, the cost support for stainless steel became stronger. In the new energy sector, the demand for ternary materials in September weakened slightly, but the supply of raw materials was relatively tight, and prices were likely to remain strong. With the marginal improvement of ferronickel and new energy, opportunities for bottom - fishing could be considered [2]. 3. Summary According to the Catalog 3.1 Research Views - **Copper**: The New York Fed's survey showed that US inflation expectations in August were relatively stable, but consumer confidence in re - employment reached a historical low.

Environmental protection - related roasting restrictions in Shanxi and Henan improved short - term sentiment, but could not reverse the oversupply. The increase in imports added pressure.

Nickel ore prices were stable. Stainless steel inventory decreased slightly, and supply increased. Raw material price increases strengthened cost support.

The position of the main contract decreased by 7,881 lots to 505,400 lots. In the international market, the expectation of a September interest rate cut is strong and rising, the U.S. dollar index is oscillating weakly, and the center of the U.S. cotton futures price has moved slightly higher, but the upward drive is weak. In the domestic market, Zhengzhou cotton futures prices are oscillating weakly, and the market is more concerned about the pressure brought by the expected high - yield of new cotton. The purchase price of seed cotton in new cotton areas is not expected to exceed 6.5 yuan per kilogram. In the short term, Zhengzhou cotton lacks clear support and is expected to oscillate at a low level.
