1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints of the Report - Overall, the sentiment in the有色金属 market is mixed. Some metals may experience price fluctuations due to factors such as supply - demand imbalances, geopolitical issues, and market expectations.
