Group 1 - The core viewpoint is that emerging industries such as artificial intelligence, electric vehicles, renewable energy, and commercial aerospace are rapidly expanding, leading to qualitative changes in the requirements for upstream materials [1] - These changes impose unprecedented stringent standards on the performance, purity, form, and functionality of materials, resulting in a significant number of metals being reclassified from bulk commodities to "critical strategic materials" or "high-tech value-added new materials" [1] - The investment logic in the upstream metal materials industry is fundamentally shifting due to the vigorous development of new fields, injecting a new growth cycle into the upstream metal materials sector from the demand side [1] Group 2 - The value of upstream metals is expected to continue to rise as the demand for materials in new industries remains robust, necessitating a growth-oriented perspective on the key materials for future technology industries [1] - The Guotai New Materials ETF (159761) tracks the New Materials Index (H30597), which focuses on the new materials industry by selecting listed companies involved in advanced basic materials, critical strategic materials, and cutting-edge new materials [1]
