Global markets-US stocks stay lower after Fed leaves rates unchanged
SPY•Earnings and AI spending remain in focus
Investors are also awaiting a wave of key earnings, with Microsoft MSFT.O and Meta META.O due to report after the market close, followed later this week by Amazon.com AMZN.O and Apple AAPL.O.
Global markets have been volatile this month as investors question the sustainability of the AI spending boom amid signs that major U.S. companies are deepening a web of AI-linked investments and continuing to funnel billions into the technology at the expense of free cash flow.
"The pressure is shifting from spending plans to returns on investment. Investors want evidence that AI capex is generating revenues now, while also strengthening the future growth outlook," said Gina Martin Adams, chief market strategist at HB Wealth.
The scrutiny comes as competition from China intensifies, both in the race to develop advanced chips and as Chinese firms roll out cheaper AI models.
