Kingboard Holdings' stock price surged 5.16% during intraday trading on Thursday, reflecting significant investor optimism.

The sharp rise is attributed to a severe tightening in the global copper clad laminate (CCL) supply chain. Korean printed circuit board (PCB) manufacturers have engaged in panic buying, with orders reportedly exceeding five times normal monthly volumes, leading to extended delivery lead times. Kingboard Laminates, a key subsidiary of the group, has raised product prices three times this year, with cumulative increases surpassing 40%.

Further bolstering sentiment, Citigroup recently upgraded its outlook on Kingboard Holdings, raising the target price from HK$48 to HK$65 and reiterating a "Buy" rating. The bank significantly lifted its earnings forecasts for the company, citing AI infrastructure investment as a key driver for shortages in materials like glass fiber, copper foil, and CCL. Citigroup also highlighted the stock's attractive valuation, with a forward price-to-book ratio far below that of its subsidiary, suggesting substantial recovery potential.
