Asian Tech Stocks Decline as SK Hynix Plunges 10% Amid AI Sector Sell-off

Asian technology stocks experienced a notable downturn, mirroring a broader sell-off in artificial intelligence (AI)-focused companies on Wall Street. South Korean semiconductor giant SK Hynix (SKHY) saw its shares plummet by nearly 10%, highlighting growing market apprehension regarding the sustainability and profitability of AI technology investments globally. This decline is attributed to both the weakening performance of US chipmakers and escalating competitive pressures in Asia.

The sell-off intensified after reports emerged of Nvidia's (NVDA) substantial $250 billion financing guarantee to OpenAI for data center leases and chip purchases, raising concerns among investors about the fragility, rather than the strength, of AI-linked demand. Concurrently, the robust initial public offering (IPO) of Chinese memory chipmaker CXMT, which achieved a valuation nearing $515 billion, fueled fears of heightened competition within the Asian semiconductor landscape. Furthermore, China's commencement of mass-producing homegrown deep ultraviolet lithography machines is seen as reducing its reliance on Dutch equipment maker ASML, narrowing the high-bandwidth memory (HBM) gap with Korean industry leaders to just three years.

Adding to the pressure, SK Hynix's second-quarter earnings, while a record, fell short of market expectations. The company reported an operating profit of 60.5 trillion Korean won (approximately $42 billion) for the three months ending in June, which was below the consensus forecast of 64 trillion won. This earnings miss amplified investor concerns about the long-term sustainability of AI spending and the return on these substantial investments. In the wake of these developments, South Korea's KOSPI index dropped over 4%, and Japan's Nikkei 225 fell by 1.2%.

These recent declines represent the third significant correction in AI-focused stocks since the sector's uptrend began in late 2022. Market analysts suggest this trend is part of a broader re-evaluation within the global economy. In an environment of higher real interest rates, the market is shifting its focus from pricing potential to demanding tangible proof of profitability. This dynamic is prompting a rotation of capital away from concentrated AI trades towards other sectors, yet the underlying bullish market trend remains intact.

However, analysts at J.P. Morgan maintain that the recent weakness in the technology sector does not signal the end of the AI investment cycle. The bank argues that investors have become overly concerned about the durability of AI spending, despite limited evidence of a fundamental slowdown. J.P. Morgan highlighted the continuous improvement of frontier AI models, strong demand for AI inference, and increasing profitability across the AI ecosystem. They do not anticipate cloud providers or hyperscalers reducing their AI investments in 2027, expecting them to leverage equity and debt markets to fund further AI infrastructure expansion. Semiconductor equipment manufacturers and companies involved in advanced packaging technologies are projected to be best positioned over the next 12 months.
