VGT’s stock plummeted 5.07% during intraday trading on Monday, extending a broader pullback in the PCB sector. The sharp decline came as the stock faced collective selling pressure following a significant rally in the prior week, which saw prices surge approximately 50% from around HKD 190 to HKD 280.

The broader PCB sector also experienced heavy selling, with peers KB Laminates and Kingboard Holdings falling 11.0% and 7.68% respectively in regular trading. Brokerages have flagged concerns over potential price wars as industry capacity faces concentrated release in the medium term, while the interim earnings window has prompted funds to lock in gains after the recent rapid appreciation.

The company had previously confirmed normal operations and a growing order backlog, with some clients releasing long-term demand through 2028. However, northbound capital net sold HKD 261 million over three days through August 7, signaling persistent short-term adjustment pressure.
