Global stock markets are experiencing significant turmoil as tech stocks, particularly in the semiconductor and AI sectors, face a deep sell-off. The Nasdaq and S&P 500 have witnessed sharp declines, driven by fears surrounding AI spending and a wave of profit-taking among leading tech companies like Micron, Alphabet, and Nvidia. The sell-off has also spread internationally, with South Korean markets plunging, reflecting a broader apprehension about rising interest rates and potential economic indicators. Despite a brief recovery in some areas, the overall trend appears to be dominated by bearish sentiments and caution among investors.
