The recent decline in global stock markets is driven by a broad tech sell-off, with the Nasdaq experiencing notable drops and AMD's shares sinking after earnings reports. Wall Street overall ended lower amid growing worries about artificial intelligence and its impact on the tech sector. The sell-off is not limited to technology stocks but reflects broader investor concerns about the future of AI and its influence on market stability. Major indices are impacted, and the sentiment remains cautious as investors reassess risks associated with the rapidly evolving AI industry.
