Reports of delays to NVIDIA's Kyber NVL144 racks prompted sharp falls in PCB and
AI-hardware suppliers, with Japan's Ibiden tumbling as much as 10% and Samsung
Electro‑Mechanics down 11% as markets priced potential slippage in next‑gen
racks into upstream PCB, substrate and materials demand. Analysts say the move
was amplified by stretched AI-sector sentiment after recent rallies; Allspring's
Gary Tan said a Kyber delay does not necessarily imply weaker AI capex and may
simply reflect longer deployment time for NVIDIA's most aggressive
next‑generation architecture. Traders also cited profit‑taking, sector rotation,
pre‑US July 4 holiday reopening caution and potential fund‑flow disruption from
a possible SK Hynix US IPO as additional drivers. Market attention now turns to
Samsung Electronics' Tuesday results for signals on memory and AI supply‑chain
demand and whether the semiconductor cycle can sustain current valuations.
