AI Rally Sends SK Hynix and Samsung Stocks Higher
South Korean chipmakers SK Hynix and Samsung Electronics surged more than 20% on July 30, 2026, as a rebound in U.S. technology stocks followed stronger-than-expected quarterly results from Amazon and Microsoft that revived optimism about AI infrastructure spending. The iShares Semiconductor ETF also jumped overnight, and Japanese semiconductor names such as Advantest, Tokyo Electron, Disco, Lasertec and Renesas Electronics rallied. Market commentary cited Microsoft’s Azure cloud strength and controlled capex as catalysts for renewed risk-on appetite toward AI-linked chipmakers.
Earnings from major cloud providers (Amazon, Microsoft) signalled continued AI infrastructure spending, triggering a sizable rally in semiconductor stocks — a material signal for tech supply chains and AI hardware demand.

Asia Tech Stocks Rebound After U.S. Chip Rally
Asian technology and chip-linked stocks rose on June 9, 2026, tracking gains in U.S. semiconductor peers as investors returned to AI‑linked names. Major movers included SK Hynix, Samsung Electronics and Seoul Semiconductor, while Japanese equipment makers Tokyo Electron, Advantest and Renesas advanced. The surge in U.S. chip shares helped lift the S&P 500 and Nasdaq, and market participants warned of continued volatility this week as investors anticipate pricing for SpaceX’s IPO and a possible wave of AI IPOs following OpenAI’s confidential filing. ORTUS Advisors’ equity strategist Andrew Jackson said the recent rotation to domestic defensive stocks is likely short‑lived and that capital could tighten after large AI listings.
Chip Stocks Surge as AI Buildout Concerns Ease
Chip stocks rallied strongly in April after a weak March driven by investor anxiety over AI infrastructure spending. Nasdaq’s PHLX Semiconductor Sector Index fell 6.3% in March but climbed roughly 35.2% from the start of April through the referenced market close as investors returned to the sector. Several major firms — including Intel, Nvidia and Apple — posted positive earnings or guidance that supported the rally. Analysts called the month’s semiconductor gains "historic," while others warned of real supply‑side constraints tied to geopolitics, such as helium export disruptions and data‑center equipment shortages related to the Iran war. The piece also notes broader AI ecosystem developments, including funding talks at Anthropic and record profits at Samsung driven by chip demand.
AI chip rally adds $2T to Micron, Intel, AMD
Chip stocks outside Nvidia surged in Q2 2026 as investors broadened AI exposure to memory and CPU suppliers. Micron rose more than 240%, Intel jumped 216% and AMD climbed 186%, together adding about $2 trillion to their combined market capitalization. Micron reported a more-than-fourfold revenue increase for the latest quarter and a jump in gross margin to 84.9%. Other AI infrastructure suppliers also posted large gains — Marvell, Arm and the VanEck Semiconductor ETF saw double- and triple-digit returns — while hyperscalers such as Alphabet, Meta, Amazon and Microsoft had mixed results. Barclays analyst Anshul Gupta attributed the moves to a rotation from AI hyperscalers into broader semiconductor ‘AI enablers.’
