Asian stocks declined on Thursday as renewed concerns about artificial intelligence investments triggered selling across semiconductor companies and Chinese equities. Mixed earnings from major US technology firms failed to reassure investors about the profitability of massive AI infrastructure spending.
South Korean chipmakers suffered some of the steepest losses, while Chinese stock markets approached bear market territory amid disappointing corporate earnings and fading expectations for government stimulus.
Meanwhile, rising crude oil prices added another challenge for Asian financial markets, increasing concerns about inflation and global economic growth.
Asian Stocks Fall as AI Investment Concerns Weigh on Markets
Asian equity markets came under pressure despite Wall Street finishing the previous session higher.
Nasdaq 100 futures declined 1.2% during Asian trading, while S&P 500 futures fell 0.6%.
Tesla shares dropped 3.3% in after-hours trading after the electric vehicle manufacturer reduced its capital expenditure forecast.
Meanwhile, Meta Platforms gained 2.2% after increasing its outlook for artificial intelligence spending.
Semiconductor equipment manufacturer Lam Research declined 7.4% following an earnings forecast that fell short of market expectations.
The mixed corporate results renewed concerns about whether technology companies can generate sufficient returns from their substantial investments in AI infrastructure.
Investors are increasingly questioning the financial sustainability of expanding data centers, advanced computing facilities and other artificial intelligence technologies.
Samsung and SK Hynix Lead South Korean Chip Stock Selloff
South Korean semiconductor companies experienced significant selling pressure as concerns surrounding the AI investment boom intensified.
The MSCI Asia Pacific Index fell approximately 1%, reflecting broad weakness across regional equity markets.
South Korea’s KOSPI declined 2.1%, while Japan’s Nikkei 225 dropped 1.1%.
Hong Kong’s Hang Seng Index recorded a steeper 2.7% decline. Meanwhile, China’s CSI 300 fell 1.6%, and the Shanghai Composite lost 1.2%.
Among major semiconductor manufacturers, SK Hynix shares plunged 4%, while Samsung Electronics declined 3.6%.
Japanese memory chip producer Kioxia fell 3.3%, and electronic components manufacturer Murata Manufacturing dropped 2.1%.
Taiwan Semiconductor Manufacturing Company (TSMC) declined 0.6%, while electronics manufacturer Foxconn lost 1%.
The widespread declines highlight growing uncertainty surrounding the global semiconductor industry.
Investors remain concerned that enormous investments in artificial intelligence infrastructure may take longer than expected to generate meaningful financial returns.
Higher financing costs and elevated technology stock valuations have also contributed to renewed speculation about a potential AI market bubble.
Nasdaq and Semiconductor Stocks Face Growing Pressure
Recent trading activity in US technology markets has reinforced concerns about the sustainability of the AI-driven stock market rally.
The Nasdaq 100 declined 5.5% during the previous week, marking its largest weekly loss since April 2025.
Meanwhile, the Philadelphia Semiconductor Index experienced eight consecutive sessions of declines, its longest losing streak since October 2008.
The weakness reflects growing investor sensitivity to corporate earnings, capital expenditure forecasts and profitability expectations.
Companies heavily exposed to artificial intelligence infrastructure have faced particular scrutiny as investors reassess the relationship between spending and potential earnings growth.
In South Korea, the central bank also maintained its benchmark interest rate following two consecutive increases.
Policymakers are balancing inflation risks against economic conditions influenced by the country’s semiconductor industry.
Chinese Stocks Approach Bear Market as Alibaba and Tencent Decline
Chinese equity markets continued to weaken amid disappointing corporate results, reduced expectations for substantial economic stimulus and concerns surrounding global technology stocks.
The CSI 300 Index fell as much as 1.6%, bringing its decline from a June peak to approximately 20%.
A sustained decline of 20% from a recent high is commonly considered the threshold for a technical bear market.
The index’s performance therefore highlights growing pressure on Chinese equities.
Alibaba was among the biggest losers in the country’s technology sector, with shares declining 5.5%.
The selloff followed government calls for stronger quality control standards across online commerce platforms.
Other major Chinese technology companies also experienced significant losses.
JD.com declined 4.2%, Meituan fell 3.9%, and Tencent dropped 3%.
Artificial intelligence companies were similarly affected, with MiniMax falling 6.8% and Z.AI losing 8.9%.
Meanwhile, memory chip manufacturer ChangXin Memory Technologies declined 4.1%.
The widespread weakness demonstrates how concerns about corporate earnings, regulatory developments and AI valuations are influencing Chinese stock market sentiment.
Rising Oil Prices Add Pressure to Asian Financial Markets
Higher energy prices created another obstacle for Asian equities as geopolitical tensions in the Middle East intensified.
Brent crude climbed approximately 1.5%, trading above $110 per barrel, following deadly attacks in Saudi Arabia that heightened concerns about potential oil supply disruptions.
Security risks surrounding shipping through the Strait of Hormuz also remained elevated.
Although crude exports through the strategic waterway recently accelerated, investors continued monitoring the possibility of further disruptions.
Higher oil prices represent a particular challenge for major energy-importing economies across Asia.
Countries such as Japan, South Korea and India depend heavily on imported crude oil, making them vulnerable to sustained increases in energy costs.
Elevated oil prices can increase transportation expenses, manufacturing costs and inflationary pressures.
These developments could also complicate central bank interest rate decisions, particularly if policymakers face persistent inflation alongside slower economic growth.
Elice Group Surges Despite Broader AI Stock Weakness
Not all artificial intelligence companies participated in the regional technology selloff.
South Korean AI cloud infrastructure provider Elice Group recorded strong gains for a second consecutive session.
The company’s shares climbed as much as 25% to 99,900 won in Seoul, moving above its initial public offering price of 90,500 won for the first time since listing.
The rally followed a 30% increase on Wednesday, when Elice shares reached their daily trading limit.
However, the company’s stock market debut had been considerably weaker.
Shares plunged approximately 32% during Tuesday’s initial trading session before rebounding sharply.
The recovery demonstrates that investors remain willing to support selected AI infrastructure companies despite broader concerns about technology valuations.
Nevertheless, the significant volatility also highlights the risks associated with newly listed artificial intelligence businesses.
Australia, Singapore and New Zealand Stocks Edge Lower
Elsewhere in Asia-Pacific markets, equity performance remained generally negative.
Australia’s S&P/ASX 200 declined 0.3%, while New Zealand’s NZX 50 fell 0.4%.
Singapore’s Straits Times Index slipped 0.2%, reflecting relatively modest losses compared with the steeper declines in South Korea and Hong Kong.
Meanwhile, India’s Nifty 50 futures dropped 0.3%, indicating a cautious outlook for the country’s equity market.
The declines reflected broader investor uncertainty surrounding artificial intelligence spending, corporate earnings and geopolitical developments.
Indonesia Stocks Rebound Following Historic Market Decline
Indonesia’s Jakarta Composite Index was a notable exception to the regional weakness, gaining 1.1%.
The advance followed a period of extreme volatility in the Indonesian stock market.
The benchmark index plunged more than 11% during the previous Friday’s session, recording its largest one-day decline since January 1998.
Additional losses followed earlier in the week before buyers returned to the market.
The selloff came after MSCI proposed reclassifying Indonesia from emerging-market status to standalone-market status.
Such a change could have significant implications for international investment flows, particularly among institutional funds tracking MSCI benchmarks.
The latest rebound suggests some stabilization, although uncertainty surrounding the proposed classification change remains an important factor for investors.
What Comes Next for Asian Stocks and the AI Sector?
The latest decline in Asian stocks highlights the increasing influence of artificial intelligence investment expectations on global equity markets.
Technology companies and semiconductor manufacturers remain particularly sensitive to changes in projected AI spending, corporate profitability and financing conditions.
Investors will continue monitoring upcoming earnings reports from major technology companies for evidence that substantial infrastructure investments can generate sustainable returns.
Chinese equities also face additional challenges from weakening corporate performance and uncertainty surrounding economic stimulus measures.
Meanwhile, elevated crude oil prices and geopolitical tensions could increase inflation risks and complicate the outlook for monetary policy across Asia.
For now, Samsung, SK Hynix and other semiconductor manufacturers remain important indicators of investor confidence in the global AI investment cycle.
Whether Asian stock markets stabilize or extend their declines may depend on corporate earnings, energy prices and the broader outlook for economic growth.
