As the year approaches its end, the US stock market has shown signs of instability, diverging from the traditionally anticipated ‘Santa Claus rally’. Major indices including the Dow, S&P 500, and Nasdaq have seen significant declines amid profit-taking and broad sell-offs, particularly in big tech stocks such as Nvidia and Tesla. Analysts are expressing concerns about a potential downturn, highlighting a lackluster performance for the last trading sessions and raising questions about the outlook heading into the new year. The closing days of the year have seen the Dow drop over 400 points, indicating a sour finish despite earlier strong gains throughout the year.
