Japan’s Nikkei 225 suffered a sharp decline on Friday as technology stocks came under heavy selling pressure. Growing concerns about the profitability of artificial intelligence investments weighed on investor sentiment, pushing the benchmark index down as much as 3% during the session.
The selloff followed significant losses on Wall Street, where disappointing earnings developments intensified questions about the enormous spending required to support the global AI boom.
Nikkei Drops 2.1% as AI Investment Concerns Grow
Japan’s Nikkei closed 2.1% lower at 63,290.11 points after falling as much as 3% earlier in the trading session.
Semiconductor-related companies led the downturn, with chip equipment manufacturers Advantest and Tokyo Electron among the hardest-hit stocks.
Advantest declined 5.9%, while Tokyo Electron dropped 5.2%, reflecting growing investor concerns about the sustainability of AI-related capital expenditure.
The selling pressure mirrored weakness in US technology stocks following earnings announcements from Amazon and Intel. Both companies reported substantial cash outflows, raising fresh questions about whether aggressive technology investments will generate sufficient returns.
Maki Sawada, an equity strategist at Nomura Securities, suggested that investors are becoming increasingly concerned about the profitability of AI investments, putting additional downward pressure on stock valuations.
Semiconductor Stocks Lead Japan’s Market Selloff
Technology and semiconductor companies experienced some of the steepest declines as investors reassessed the outlook for AI-related businesses.
Among the biggest losers, Ibiden plunged 15.2%, while Lasertec fell 8.8%. SoftBank Group also suffered a substantial decline, losing approximately 6%.
The weakness extended across several major technology companies, highlighting the vulnerability of AI-linked stocks to changing investor expectations.
Of the Nikkei’s 225 constituents, 123 finished lower, while 100 recorded gains and two remained unchanged.
Despite Friday’s sharp decline, the Nikkei managed to finish the week approximately 1% higher.
Meanwhile, the broader Topix index performed relatively better, falling around 1% during Friday’s session and ending the week largely unchanged.
Bank of Japan Holds Interest Rates Steady
Monetary policy developments provided another important backdrop for Japanese equities.
The Bank of Japan maintained its benchmark interest rate, meeting widespread market expectations.
However, the central bank surprised investors by announcing plans to accelerate sales of its exchange-traded fund holdings beginning in January.
Despite the unexpected announcement, Japanese stocks showed little immediate reaction to the policy adjustment.
Instead, corporate earnings and concerns surrounding artificial intelligence spending remained the primary drivers of market activity.
Lower Oil Prices Offer Support to Japanese Equities
Outside the technology sector, declining crude oil prices helped limit some of the broader market weakness.
Optimism surrounding ongoing Middle East peace negotiations contributed to downward pressure on energy prices.
Lower oil costs generally benefit Japan because the country relies heavily on imported energy, particularly supplies originating from the Middle East.
Cheaper energy can help reduce operating expenses for Japanese businesses, ease inflationary pressures and improve the outlook for corporate profitability.
Consequently, weaker oil prices provided a degree of support to domestic equities despite the significant technology-driven selloff.
Konami and Oriental Land Defy the Market Downturn
Although semiconductor and AI-related stocks struggled, several Japanese companies delivered impressive gains following their earnings announcements.
Video game developer Konami emerged as the Nikkei’s strongest percentage performer, surging approximately 15%.
Oriental Land, the company operating Tokyo Disney Resort, also recorded a substantial advance, climbing 8.5%.
These gains demonstrated that company-specific earnings results continued to create opportunities even as the broader market faced selling pressure.
AI Spending Fears Keep Technology Stocks Under Pressure
The latest Nikkei decline reflects growing uncertainty about the financial returns from the global artificial intelligence investment boom.
Major technology companies continue allocating substantial resources to AI infrastructure, semiconductor development and computing capacity. However, investors are increasingly questioning how quickly those expenditures will translate into sustainable earnings growth.
Recent financial results from companies in Japan, the United States and South Korea have contributed to significant volatility across technology markets.
While the Nikkei retained a modest weekly gain, Friday’s sharp decline underscored how sensitive semiconductor and AI-related stocks remain to corporate earnings and changing expectations for future profitability.
