1. Report Industry Investment Rating There is no information about the report industry investment rating in the provided content. 2. Core Viewpoints - Due to the weakening US employment market, the expectation of the Fed's interest - rate cut is rising. However, the traditional consumption off - season in China suppresses downstream demand, and the inventory of electrolytic copper at home and abroad fluctuates. The Shanghai copper price may still have room to fall. It is recommended that investors hold their previous short positions cautiously and pay attention to the support and pressure levels of different copper markets [2]. 3.
