- Sandisk issued underwhelming fiscal 2027 revenue guidance that sent its shares lower in premarket trading despite the company's Q4 earnings beat.
- SK Hynix plummeted about 10% premarket as Sandisk's guidance triggered selloffs among memory makers in South Korea and Japan, dragging related market indexes down.
- Nvidia and several major AI chipmakers were largely flat or dipped only slightly in premarket trading, showing the selloff was concentrated in memory rather than spreading broadly across AI names.
- Chip equipment makers mostly gained in premarket, with MKS and ASML rising after strong quarterly results.
- Applied Materials traded in the red even as peers MKS and ASML rose, making it the outlier among chip equipment names.
Why it matters: A single memory maker's forward outlook moved an entire sector premarket, with SK Hynix losing roughly 10% and Japanese memory peers following — showing how thin sentiment is across the AI memory trade right now. The split between falling memory stocks and rising equipment names (ASML, MKS up on strong results) underscores that investors are penalizing near-term guidance in the memory chain even as they reward long-cycle equipment strength.
