KB Laminates (01888) experienced a significant decline of 6.70% during intraday trading on Monday, as the stock continued to retreat from recent highs amid broader market pressures.

The electronic components sector is facing widespread selling pressure, with parent company Kingboard Holdings and sector peers like Sunny Optical also showing notable declines. This pullback follows a parabolic year-to-date rally of over 570% for KB Laminates, which was previously driven by AI-fueled demand for copper-clad laminates and multiple rounds of product price hikes totaling over 40% in cumulative increases.

Recent market filings disclosed that Kingboard Holdings conducted a substantial block trade of 155 million shares, while the parent company's major shareholder has cumulatively cashed out approximately HK$8.944 billion in recent days, adding to near-term selling pressure as investors take profits following the stock's remarkable run.
