Asian stock markets delivered mixed results on October 19, as concerns about the sustainability of AI-related investment continued to influence investor sentiment.
South Korea’s Kospi rose 1.8% after sharp losses the previous week, while Japan’s Nikkei 225 declined 0.6%. Chinese mainland shares edged higher following stronger-than-expected economic growth data, while Hong Kong’s market was closed for a public holiday, according to market reports.
AI Spending and Credit Risks in Focus
Investor concerns have extended beyond technology companies’ share prices to the cost of financing the data centers, chips and other infrastructure required to support AI development.
Recent declines in AI-related stocks and bonds have raised questions about whether future revenue growth will justify the industry’s substantial investment commitments. The pressure has also drawn attention to borrowing costs and the financial exposure of companies expanding their AI infrastructure.
Markets are entering a closely watched week of corporate earnings, with results and forecasts from major technology companies expected to provide further indications of demand for AI products and infrastructure.
