On June 4, Shenghong Tech (02476.HK) declined 3.93% in regular trading to HK$404.8, with turnover of HK$277 million, extending a multi-session pattern of selling pressure.

On the news front, the company faces a confluence of negative catalysts from index-related passive selling. According to official announcements from China Securities Index Co. and Shenzhen Stock Exchange, Shenghong Tech is being removed from the CSI 300, SZSE Component, and ChiNext indices, with adjustments taking effect between June 12-15. The removals stem from the company's average free-float market cap ranking falling outside the top 300, total market cap sliding beyond the top 500 in Shenzhen, and intensified competition from newly listed AI computing stocks pushing it out of the ChiNext top 100.

Additionally, data shows the stock has experienced six consecutive days of net main capital outflows totaling RMB 7.16 billion, reflecting sustained institutional selling. The PCB sector also faces headwinds from surging upstream raw material costs, with supply-demand gaps widening as Japanese and Korean suppliers show limited expansion willingness.
