On June 2, Guanghe Technology fell 3.21% in regular trading, trading at 156.5 HKD/share, with trading volume of approximately 80.68 million HKD. The decline extends the previous session's sharp selloff driven by surging upstream raw material costs across the PCB industry.

On the news front, PCB concept stocks have continued to weaken as upstream raw material prices surge and the supply-demand gap widens. According to institutional analysis, major supplier KB Laminates has undergone multiple rounds of price hikes since early last year, with cumulative increases exceeding 40%. The non-linear growth in computing infrastructure has driven rapid demand for PCB materials, while traditional Japanese and Korean suppliers remain reluctant to expand capacity, further exacerbating supply-demand imbalances. Market concerns over cost pressures and profitability outlook for PCB manufacturers including Guanghe Technology continue to weigh on sentiment.

Within the Electronic Components sector, KB Laminates fell 3.46%, Kingboard Holdings fell 3.69%, and VGT fell 2.86%, while Sunny Optical rose 1.09% and Lens Technology rose 6.01%.
