On June 24, China National Building Material rose 5.95% in regular trading, trading at HKD 5.51/share, with turnover of HKD 204 million. The stock had declined for three consecutive sessions prior, accumulating a loss of over 14%, triggering a technical rebound from oversold levels.

On the news front, the fifth round of electronic cloth price increases this year has been implemented, with AI computing demand continuing to drive fiberglass sector strength. Industry analysis indicates that weaving machine supply bottlenecks and AI specialty cloth production lines crowding out ordinary electronic cloth capacity have created a persistent structural shortage, with prices expected to continue rising in the second half. High-end AI servers require PCBs with 20 to 30 layers, consuming far more electronic cloth per unit than traditional servers.

Notably, the broader Construction Materials sector traded lower, with Conch Cement down 1.39%, West China Cement down 1.92%, and BBMG down 1.69%. China National Building Material led the sector against the trend, reflecting the market assigning differentiated valuation to its fiberglass business driven by AI-related demand.
