On June 16, Guanghe Technology fell 3.22% in regular trading, trading at 175.4 HKD/share, with turnover of approximately 91.51 million HKD. The stock surged 7.88% the previous session amid a broad PCB sector rally, triggering profit-taking pressure today.

On the industry front, copper-clad laminate (CCL) manufacturers have issued Q3 price hike notices since early June, with increases generally ranging from 10% to 15%. CCL prices have risen approximately 40% year-to-date, intensifying cost pass-through pressure on downstream PCB manufacturers. Citi noted in a research report that major CCL producers capacity growth stands at just over 20%, far below the pace of downstream PCB expansion. As AI demand accelerates in Q3, some PCB makers may face CCL allocation shortages.

The upstream-downstream divergence persisted on the day, with KB Laminates rising 7.61% while downstream names remained under pressure. The company primarily engages in R&D, production, and sales of multi-layer printed circuit boards, serving sectors including servers, consumer electronics, communications, and automotive electronics.
