On June 10, Guanghe Technology (01989.HK) fell 3.68% in regular trading, trading at HKD 176.0/share, with trading volume of HKD 37.90 million.

On the news front, the stock surged over 10% in the previous session as the PCB sector rallied collectively, and today's decline reflects profit-taking pressure. At the industry level, major copper-clad laminate (CCL) manufacturers have issued Q3 price hike notices since early June, with increases generally ranging from 10% to 15%. The continued rise in upstream raw material costs is weighing on downstream PCB manufacturers' ability to pass through costs and maintain profit margins.

The upstream-downstream divergence persisted on the day, with upstream supplier Kingboard Holdings rising 1.06%, while downstream peers VGT fell 2.52% and FIT Hon Teng dropped 8.72%. Market concerns over PCB manufacturers' margin compression amid surging input costs continue to weigh on sentiment across the downstream segment.
