On June 29, China National Building Material fell 6.3% in regular trading, trading at HKD 5.53/share, with turnover of HKD 236 million. The decline represents a continuation of profit-taking pressure following the stock's volatile pattern of sharp rallies and swift pullbacks in recent sessions.

On the news front, the stock surged over 14% on June 25 driven by the fifth round of 15% price hikes by Kingboard Laminates on FR-4 copper-clad laminates, with electronic cloth prices up over 70% year-to-date. However, after that spike, the stock fell 7.91% on June 26 as accumulated gains triggered concentrated selling. The current decline extends this pattern, with short-term profit-taking pressure continuing to unwind. Meanwhile, the Construction Materials sector remains broadly weak, with Dongwu Cement down 2.42%, HX Building Material down 1.11%, Conch Cement down 0.77%, and West China Cement down 0.72%, amplifying downward pressure.

Notably, on June 28 the company announced three world-class high-performance carbon fiber production lines commenced operations at its Zhongfu Shenying base, covering general, high-strength, and high-modulus categories with designed capacity of 31,000 tons.
