Why SK Hynix (SKHX) fell 5.87%
SK Hynix (SKHX) fell 5.87% on October 30, 2026 — Samsung, Alphabet results disappoint; Asia slides.
What happened
SK Hynix fell 5.9% as Asian stocks turned mixed after Alphabet and Samsung results disappointed, and more tech earnings are ahead.
Why it moved
Samsung's disappointing results hit the memory and AI-hardware complex that SK Hynix shares, so investors marked down the whole group, and SK Hynix moved with the regional selloff.
Why it matters
Within the Korea Tech theme, SK Hynix is the HBM leader, and the AI-driven memory rally is now being tested as sentiment toward Korean chip names weakens.
What would break the thesis
Watch whether SK Hynix can hold up through the upcoming tech earnings; a clean HBM demand signal would reverse the sentiment hit, while more weak chip results would deepen the group-wide selling.
