雅下水电站行情继续演绎，建材ETF（159745）、基建ETF（159619）大涨

Core Viewpoint - The launch of the Yarlung Tsangpo River downstream hydropower project, with a total investment of approximately 1.2 trillion yuan, is expected to stimulate demand across multiple industries, including construction materials and infrastructure [3]. Demand Side - The Yarlung Tsangpo River project is a national strategic initiative that encompasses hydropower construction, infrastructure development, ultra-high voltage transmission, equipment manufacturing, civil explosives, and cement supply, which will gradually release demand along the upstream and downstream industrial chains [3]. - Recent central urban work meetings have emphasized the need to advance the renovation of urban villages and old housing, as well as the upgrading of outdated pipelines, which is likely to accelerate the introduction of related supporting policies, thereby boosting demand for construction materials and infrastructure [3]. Supply Side - The ongoing "anti-involution" policies are aimed at stabilizing growth in key industries, including steel and construction materials. The Ministry of Industry and Information Technology announced a new round of initiatives to optimize supply and eliminate outdated production capacity [3]. - The construction industry has advocated against "involution," and the China Cement Association has issued opinions to promote high-quality development in the cement sector, indicating that these policies may improve the industry landscape and benefit leading companies in the construction and materials sectors [3]. Investment Perspective - The valuation logic for cyclical sectors has shifted from "weak expectations - weak reality" to "strong expectations - weak reality," indicating that the bottom region is becoming clearer and the cost-effectiveness of investments is improving [4]. - Sectors such as construction materials, infrastructure, and steel are expected to directly benefit from the implementation of "super projects," with significant potential for both performance and valuation expansion. Investors are encouraged to pay attention to construction materials ETF (159745), infrastructure ETF (159619), and steel ETF (515210) [4].
