On June 2, Shenghong Technology (02476.HK) declined 3.1% in regular trading, trading at HK$402.2/share, with trading volume of HK$406 million, extending the PCB sector selloff that began the prior session.

On the news front, the PCB industry is facing mounting pressure from surging upstream raw material prices, with copper prices remaining elevated and glass cloth supply tightening significantly. Kingboard Laminates has implemented its fourth price hike this year — board materials up 10% and prepreg up 20% — pushing cumulative increases beyond 40%. Analysts note that non-linear growth in computing infrastructure has driven PCB material demand sharply higher, while Japanese and Korean suppliers show weak expansion intent, causing the supply-demand gap to widen further. On June 1, the broader PCB sector saw broad-based declines, with Kingboard Laminates falling 11.54% and Guanghe Technology dropping 10.11%. Additionally, significant main force net outflows of over HK$2.2 billion were recorded in Shenghong Technology on June 1, indicating sustained institutional selling pressure carrying into the current session.

Within the Electronic Components sector, KB Laminates fell 3.04%, Kingboard Holdings fell 3.78%, and FIT Hon Teng dropped 3.87%, reflecting continued sector-wide weakness.
