SK Hynix is trading 4.88% down at $994.00 as hotter U.S. inflation heightened rate-hike concerns and pressured semiconductor stocks. - Reuters and Bloomberg reported broad pressure across chipmakers and Asian markets on October 15; no new SK Hynix announcement was reported as explaining the move. - Investor doubts about AI infrastructure costs and financing also weighed on the sector. CXMT’s reported memory-technology progress raised competition concerns, but is sector context rather than a clear new company-specific catalyst.
