The US labor market demonstrated robust growth with the addition of 256,000 jobs in December, far surpassing the expected 160,000. This strong jobs report triggered a significant sell-off in stocks, with the Dow tumbling over 450 points as investors reassessed the likelihood of Federal Reserve interest rate cuts. The unemployment rate fell to 4.1%, signaling a surprisingly strong economy that could hinder quick rate reductions. Wall Street responded negatively to this positive economic news, with major indices, including the Nasdaq and S&P 500, experiencing substantial declines. Traders are now adjusting their forecasts for future Fed actions, potentially delaying rate cuts until October.
