"Yangtze River Underwater High-Speed Rail" Rapid transit equipment concepts surge strongly, Jinying Heavy Industry hits the daily limit with its first board.

On March 31, rail transit equipment concept stocks surged strongly. Ganying Heavy Industry (301048.SZ), Shenzhou High-Speed Railway (000008.SZ), Jinxi Axle (600495.SH), and China Railway Construction Industry (600528.SH) hit the daily limit, while Tongye Technology (300960.SZ), Tieda Technology (920541.BJ), Tieke Rail Transit (688569.SH), Riyueming (300906.SZ), Jiaokong Technology (688015.SH), and others also rose in tandem.

On the news front, CCTV Finance reported that China will build high-speed rail under the Yangtze River. The total investment in the high-speed rail along the river exceeds 500 billion yuan, driving upstream and downstream industries to grow added value by nearly 1.5 trillion yuan.

In addition, on the same day, the ultra-large diameter shield tunneling machine “Fujie No.” independently developed by our country successfully rolled off the production line in Nantong, Jiangsu. It will be used for the Yangtze River tunnel project of the Yanyi High-Speed Railway. This project is the first high-speed rail shield tunnel in China that uses socket-segment tunnel linings. The construction of the tunnel will help propel China’s ultra-large diameter underwater shield tunnels into an era of fully intelligent construction.

Caitong Securities said that amid market volatility, construction has demonstrated strong resilience and toughness against downturns. The firm continues to like steel structure + large construction + coal chemical industry leading companies. Last week, the CSI 300 fell by a relatively large margin, while the construction sector declined by a smaller amount. Construction transformation-related stocks performed better, and coal chemical industry, steel structures, large construction, and others also delivered better gains. Oversold and high-quality outbound private sector leaders companies achieved a rebound as expected. We believe that external factors are still affecting market risk appetite and the main themes to some extent, but based on domestic fundamentals, fixed-asset investment moving upward is a relatively certain main theme, and the fixed-asset investment data for January and February also corroborated our earlier views.
