South Korea’s chip heavyweights SK Hynix and Samsung Electronics skyrocketed in Seoul on Friday, tracking a sharp rally in U.S. technology stocks after blockbuster earnings from Amazon and Microsoft revived optimism around artificial intelligence spending.
SK Hynix closed nearly 30% higher, marking its best day on record. Samsung closed nearly 27% higher, also clocking its highest single-day gains. LG Innotek advanced 21.23% and Seoul Semiconductor rose 15%.
Japanese chip stocks also rallied sharply. Advantest climbed more than 16%, while Tokyo Electron gained 6.24%, Disco rose 12.74%, Lasertec advanced 12.74% and Renesas Electronics added 7.7%. SoftBank Group, a key artificial intelligence proxy as its owns Arm, also jumped 13.8%.
Taiwan’s TSMC surged almost 10%.
The chip rally in Asia marks a sharp reversal from this week’s bruising sell-off, as semiconductor stocks were battered by concerns over lofty AI valuations and signs of intensifying competition from Chinese memory chipmakers.
The iShares Semiconductor ETF (SOXX) surged more than 8% overnight, as investors piled back into AI-linked chipmakers following stronger-than-expected cloud results from the two U.S. tech giants.
Amazon jumped more than 9% in extended trading after reporting second-quarter revenue that beat analysts’ expectations, driven by continued strength in its cloud-computing business. Microsoft had rallied 16% during Thursday’s regular session after reporting faster-than-expected Azure cloud growth, reinforcing confidence that AI infrastructure spending remains robust.
Andrew Jackson, head of equity strategy at Ortus Advisors, said Microsoft’s stronger-than-expected quarterly results “sparked a huge rebound for risk-on and AI,” helping reverse the recent sell-off in technology stocks.
He wrote in a note on Friday that investors were reassured after Azure cloud revenue beat expectations while management kept capital spending “in check,” noting that a “‘spend at all costs’ mentality has been punished by the market.”
