South Korea’s leading semiconductor manufacturers, SK Hynix and Samsung Electronics, experienced an unprecedented surge in their share prices on Friday, with both companies clocking their best single-day performances on record. This significant rally, which saw shares climb by nearly 30% and 27% respectively, mirrored a broader upturn in U.S. technology stocks, fueled by blockbuster earnings reports from Amazon and Microsoft that revitalized confidence in artificial intelligence investments.

The positive momentum was not confined to South Korea, as chip-related stocks across Asia also saw substantial gains. Japanese semiconductor firms like Advantest, Tokyo Electron, Disco, Lasertec, and Renesas Electronics all advanced significantly, with Advantest climbing over 16%. Taiwan Semiconductor Manufacturing Company (TSMC) also surged by almost 10%. Even SoftBank Group, a key player in the AI landscape through its ownership of Arm, jumped by 13.8%, underscoring the widespread impact of renewed AI optimism.

This robust performance marks a sharp turnaround for the semiconductor sector, which had recently faced a bruising sell-off. Concerns over lofty AI valuations and intensifying competition from Chinese memory chipmakers had previously battered stock prices. However, the iShares Semiconductor ETF (SOXX) surged more than 8% overnight, as investors eagerly reinvested in AI-linked chipmakers following the stronger-than-expected cloud results from the two U.S. tech giants.

Amazon’s second-quarter revenue surpassed analysts’ expectations, driven by the sustained strength of its cloud-computing division. Similarly, Microsoft’s Azure cloud growth outpaced forecasts, reinforcing the market’s belief in the continued robustness of AI infrastructure spending. Andrew Jackson, head of equity strategy at Ortus Advisors, noted that Microsoft’s results specifically “sparked a huge rebound for risk-on and AI,” helping to reverse the recent downturn in technology stocks and reassuring investors that capital spending was being managed responsibly, avoiding a “spend at all costs” mentality that the market has previously penalized.

Key Takeaways

• South Korean chip giants SK Hynix and Samsung Electronics achieved record single-day gains, with shares soaring by nearly 30% and 27% respectively.
• The rally was ignited by stronger-than-expected earnings from U.S. tech leaders Amazon and Microsoft, which renewed investor confidence in robust AI infrastructure spending.
• The positive sentiment extended across Asian semiconductor markets, including Japan and Taiwan (TSMC), reversing a recent sell-off driven by concerns over AI valuations and competition.
