SK Hynix, a leading South Korean chipmaker, reported a dramatic 557% year-on-year surge in operating profit to 60.54 trillion won ($41.6 billion) for the second quarter of 2026, driven by robust demand for memory chips amid the expansion of artificial intelligence infrastructure [1]. Despite this record profit, the company's results fell short of market forecasts, prompting a sharp decline in its share price [1][2]. On Wednesday, SK Hynix shares dropped more than 10% in South Korea, reflecting investor disappointment over the earnings miss [2].
The sell-off extended across Asian technology stocks, with Samsung Electronics losing over 4%, LG Innotek falling 9%, and Seoul Semiconductor dropping more than 6% [2]. Japanese chipmakers also suffered, as Kioxia declined 10% and Tokyo Electron fell 8.5%. SoftBank Group, a major AI investment proxy due to its stake in Arm, lost more than 7% [2]. Taiwan's TSMC was down 1.32%, while China's ChiNext 300 index and Hang Seng China Semiconductor Chips Index dropped 1.83% and over 5%, respectively [2].
The declines followed another weak session for U.S. semiconductor stocks, with Nvidia opening lower but closing flat, Intel dropping nearly 6%, AMD losing 8%, Micron and Seagate both down more than 8%, Western Digital sinking nearly 7%, and Sandisk shedding 14%. SK Hynix's U.S. shares fell 9% [2].
Despite the sharp pullback, some analysts remain optimistic. Kieron Poon, investment director of Asian equities at Aberdeen Investments, noted that the volatility has not altered their long-term positive outlook, and the market pullback has created opportunities to invest in high-quality businesses at more attractive valuations [2]. David Riedel, founder and president of Riedel Research Group, commented that the sell-off reflects investors 'giving back a little bit of the froth' in the AI market, but asserted that the market remains healthy and memory chipmakers 'will be fine,' though they must relinquish some of their recent gains [2].
Meanwhile, Chinese internet stocks listed in Hong Kong bucked the broader regional weakness, with Tencent and Meituan rising 3.6% and 2.7%, respectively. Alibaba, Baidu, and Kuaishou also traded higher [2].
CONCLUSION
SK Hynix's record Q2 profit, while impressive, failed to meet market expectations, triggering a broad sell-off in Asian semiconductor stocks. Despite short-term volatility and concerns over the sustainability of the AI-driven chip boom, some analysts view the pullback as an opportunity to invest at more reasonable valuations. The market remains fundamentally healthy, with memory chipmakers expected to weather the correction.
