U.S. stock markets have taken a significant hit, with the Nasdaq plunging more than 4% and the S&P 500 experiencing its worst day of the year as tech stocks, particularly chipmakers, faced renewed selling pressure. A strong jobs report has heightened concerns about potential interest rate hikes by the Federal Reserve, prompting a sell-off across major indexes. Market analysts note that the tech sector, which had recently shown some resilience, is now in a precarious position, with fears swirling around a potential bubble. As investors assess the implications of the labor market data, Wall Street braces for continued volatility.
