On July 16, Kingboard Laminates (01888.HK) declined 9.57% in regular trading, trading at HK$50.2/share, with turnover of HK$794 million. The stock extended its retreat from recent highs as the PCB sector faced profit-taking following a sharp rebound earlier in the week.

The decline comes amid continued selling pressure from company insiders. Independent non-executive director Kung Wing Tak sold 50,000 shares on July 13 at HK$52.422 per share. This adds to a series of director disposals since late June, including executive director Zhang Guoqiang selling 200,000 shares at HK$71.5 on July 8 and Zhang Guohua selling 300,000 shares at approximately HK$98.59 on June 30. On the prior trading day, market commentary noted PCB stocks were under pressure from profit-taking after the mid-year earnings rally. Parent company Kingboard Holdings fell 7.32% in today's session, reflecting broad-based weakness across the PCB supply chain.
