Report Industry Investment Rating No relevant content provided. Core Viewpoints - The Shanghai copper market maintained strong performance with a slight increase in open interest. Favorable domestic and overseas macro - factors, such as rising overseas interest - rate cut expectations and a weak US dollar index, along with a decline in Mysteel's electrolytic copper social inventory, may keep copper prices strong [5]. - The Shanghai aluminum market oscillated upward with a slight decrease in open interest.

Report Industry Investment Rating There is no information provided regarding the industry investment rating in the given content. Core Views - **沪铜**: The Shanghai copper futures showed a strong and volatile trend today with a continuous decline in open interest. The domestic macro - environment is favorable, while the overseas situation is poor. Recent US economic data has continuously fallen short of expectations, and there is a need to be cautious about overseas recession trading. On the industrial side, the upstream maintains high production, and with the downstream in the off - season, demand is marginally weakening, and electrolytic copper inventories tend to rise. Technically, attention should be paid to the technical support at the 78,000 level [5]. - **沪铝**: The Shanghai aluminum futures increased in open interest and rose today, with the main contract price breaking through the 20,600 mark. The domestic macro - environment has warmed up, and as aluminum has a strong domestic pricing ability, the price has risen significantly. In the industrial aspect, in the off - season, aluminum rods are showing a stockpiling trend, and electrolytic aluminum is also stockpiling. With the macro - environment warming up and the industry being bearish, the futures price is expected to run strongly [6]. - **沪镍**: The Shanghai nickel futures decreased in open interest and rose today, and the main contract price broke through the 121,000 mark. The domestic environment was favorable today, and the non - ferrous metal sector generally showed a strong trend. The open interest of nickel has been continuously decreasing, indicating a strong willingness of short - sellers to close their positions. Technically, attention should be paid to the technical support at the 120,000 level [7]. Summary by Related Catalogs 1.

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - On July 28, polysilicon and industrial silicon both fluctuated weakly and hit the daily limit. The main polysilicon 2509 contract closed at 49,405 yuan/ton, with an intraday decline of 5.84%, and the position decreased by 18,873 lots to 136,000 lots. The main industrial silicon 2509 contract closed at 89,150 yuan/ton, with an intraday decline of 8%, and the position decreased by 44,246 lots to 279,000 lots [2]. - Industrial silicon is in the marginal game between coal mine disturbances and large - scale factory restarts, with limited callback space.
