U.S. stock markets ended the week with significant losses, despite a Friday rally and some positive news throughout the week from corporate disclosures and government economic data. The decline was driven by fears of overvaluation in technology companies and whether artificial intelligence will generate enough profits to justify the massive spending these companies have poured into supporting these advanced technologies. The Nasdaq Composite posted the biggest losses, continuing its decline for a third consecutive week — the longest losing streak since March. This time, it fell by 2.74% to 22,273.08 points. The S&P 500 index dropped by 1.95% to 6,602.99 points, and the Dow Jones fell by 1.91% to 46,245.41 points.
