KB Laminates (01888) experienced a significant intraday decline, with its stock price plummeting 5.02% during Monday's trading session.

The sharp drop was primarily driven by sustained insider selling pressure from multiple company directors in recent weeks, which has heavily weighed on market confidence. Specific transactions include executive director Zhang Guoqiang selling 200,000 shares on July 8, Zhang Guohua disposing of 300,000 shares on June 30, and three directors collectively selling approximately 896,000 shares on June 26.

Additionally, the broader AI hardware sector pullback has continued to suppress near-term share price momentum, despite Citi recently raising its target price for the company and maintaining a buy rating based on copper foil price hikes exceeding expectations.
