On June 3, Guanghe Technology (01989.HK) rose 3.57% in regular trading, trading at 170.7 HKD/share, with trading volume of 26.38 million HKD.

The rebound follows a sharp multi-day selloff in the PCB sector driven by surging upstream raw material costs. KB Laminates, a key laminate supplier, had implemented its fourth price hike of the year with cumulative increases exceeding 40%, citing elevated copper prices and tightening glass cloth supply. Guanghe Technology had declined approximately 10.92% on June 1 and a further 3-6% on June 2 as markets priced in margin compression risks for PCB manufacturers.

On June 3, the broader Electronic Components sector staged a recovery, with FIT Hon Teng up 7.5%, KB Laminates up 6.62%, Sunny Optical up 4.52%, and Kingboard Holdings up 1.91%. The rebound comes amid sustained strong AI server demand, with Dell recently reporting AI server revenue of $16.1 billion (up 757% YoY) and raising full-year AI server guidance to $60 billion. Guanghe Technology serves as Dell's core PCB supplier, with Dell accounting for approximately 30% of its revenue.
