Key Takeaways:
- Kingboard Laminates plunges 11% leading HK PCB sector decline
- Four PCB-related stocks fall between 4% and 11% on July 28
- Selloff mirrors global chipmaker weakness with KOSPI down 7%
Key Takeaways:

Hong Kong-listed printed circuit board stocks tumbled July 28, with Kingboard Laminates plunging 11 percent to lead a sector-wide selloff.
Traders pointed to weakening demand from downstream electronics and a deepening global chipmaker rout as the primary drivers, with South Korea's KOSPI sliding 7 percent in the same session, according to exchange data. The KOSPI decline deepened as a global selloff in semiconductor stocks accelerated.
Kingboard Laminates (01888.HK) fell 11.05 percent, while parent company Kingboard Holdings (00148.HK) dropped 7.29 percent, according to exchange data. Shengyi Technology (02476.HK) declined 5.36 percent, and Han's CNC (03200.HK) lost 4.21 percent. The four stocks span the PCB supply chain from laminate production to manufacturing equipment.
The selloff points to potential headwinds for the Asian semiconductor supply chain, where PCB makers serve as a bellwether for electronics demand. Investors will watch for upcoming earnings reports from major PCB producers for further guidance on order visibility and pricing power.
The broader Hang Seng Index also faced pressure, tracking losses across regional equity markets as technology stocks came under renewed selling pressure.
