On June 22, China National Building Material (03323.HK) fell 5.16% in regular trading, trading at HK$5.65/share, with turnover of HK$375 million. The decline came as the broader construction materials sector weakened and investors locked in gains following the stock's sharp rally earlier in the month.

The construction materials sector saw broad-based selling pressure, with Conch Cement down 2.31%, West China Cement down 4.91%, Huaxin Building Materials down 3.26%, CR Building Materials Technology down 2.75%, and BBMG down 1.64%. China National Building Material had surged over 20% on June 17 after its subsidiary China Jushi confirmed batch supply of specialty fiber cloth products and announced an RMB 800 million capital increase to accelerate electronic-grade fiberglass projects. The rapid prior appreciation created significant profit-taking pressure as momentum faded.

China National Building Material is principally engaged in the production and sale of cement, concrete, glass fiber, composite materials, and lightweight construction materials, with operations primarily in the domestic market.
