LONDON/SINGAPORE (Reuters) -Investors hammered technology stocks on Monday, sending the likes of Nvidia and Oracle plummeting, as the emergence of a low-cost Chinese artificial intelligence model cast doubts on dominance of U.S. companies in this sector. Tech-heavy Nasdaq slid 3.1%, while the S&P 500 dropped 1.8%.
