Asian stock markets experienced a significant decline on Thursday, with South Korea's KOSPI index plunging nearly 8% and Japan's Nikkei index falling about 5%. This sharp drop was driven by a global selloff in technology and artificial intelligence (AI)-related stocks, following a steep decline in US tech shares overnight.
- The KOSPI index fell nearly 8% amid heavy selling of major chip makers.
- The Nikkei index dropped 5%, extending its losing streak to six sessions.
- US tech stocks declined after inflation data raised concerns about interest rate hikes.
- Chip makers like SK Hynix and Samsung Electronics faced sharp losses.
- China's breakthrough in chip technology added pressure on global players.
Why did Asian stock markets fall sharply on Thursday?
The Asian markets opened in deep red following a global rout in technology stocks. The selloff was triggered by a decline in US tech shares after inflation data showed a higher-than-expected Consumer Price Index (CPI) of 3.7% for September, above the forecast of 3.6%. This raised concerns about potential interest rate hikes, leading investors to book profits in overheated sectors like AI, data centers, and chip manufacturing.
How did inflation data affect investor sentiment?
The elevated inflation numbers increased expectations of another interest rate hike by the Federal Reserve. The probability of a 25 basis points rate increase in the upcoming policy meeting rose from 22% to 27%, according to the CME FedWatch tool. Higher borrowing costs pose risks to AI-related companies, which often rely on debt financing for growth.
Which companies were most affected by the selloff?
Major chip makers experienced significant losses. In the US, NVIDIA, Broadcom, Micron, Advanced Micro Devices, and Intel all saw their shares fall between 3% and 6%. In South Korea, SK Hynix shares dropped 11.2%, and Samsung Electronics fell 9.4%. These two companies represent over half of the KOSPI index, heavily influencing its steep decline.
What happened in Japan's stock market?
Japanese AI-related stocks such as Kioxia Holdings, Advantest, Lasertec, and SoftBank Group also declined sharply, with some falling as much as 9%. This contributed to the Nikkei index's 5% drop and its continued losing streak over six trading sessions.
How did developments in China impact the market?
China's memory chip maker ChangXin Memory Technologies announced a breakthrough with a new 4-F squared memory cell architecture, which allows more cells in the same chip size compared to previous technology. This innovation surprised global chip makers like SK Hynix, Samsung Electronics, and Micron. However, ChangXin still faces equipment shortages for manufacturing these chips, which may limit immediate competitive pressure.
What are the key takeaways from this market movement?
- Global inflation concerns and potential interest rate hikes are causing investors to reduce exposure to tech and AI stocks.
- Major chip makers are vulnerable due to high valuations and reliance on debt financing.
- Technological advancements in China add competitive pressure to established global players.
- Market volatility is likely to continue as investors reassess risks in the tech sector.
