On July 21, Guanghe Technology rose 4.76% in regular trading, trading at 120.1 HKD/share, with turnover of approximately 2.21 million HKD.

On the news front, the PCB sector is extending its rebound as market sentiment recovers following the digestion of NVIDIA Kyber NVL144 delay concerns. Semiconductor research firm SemiAnalysis previously disclosed that NVIDIA's Kyber NVL144 rack architecture was delayed over 12 months due to PCB mid-board yield bottlenecks, which had triggered consecutive sharp pullbacks across the AI server high-speed PCB supply chain. However, NVIDIA responded that its overall product roadmap remains unchanged, and UBS noted the delay only involves the top-tier flagship solution with limited impact on full-year performance. After sustained corrections, market sentiment has gradually stabilized, with the PCB sector resuming its upward trajectory. Peer KB Laminates also gained 2.08% on the same day.
