The US stock market is experiencing a robust surge as the Santa Claus rally ignites, with the S&P 500 and Dow Jones both closing at record highs. In a holiday-shortened trading session, the S&P 500 hit an all-time high for the first time in over a decade on Christmas Eve. Strong economic data and bullish trends in technology stocks, particularly Nvidia and Google, are driving investor confidence, marking continuous gains across major indices. As Wall Street hovers near these record levels, analysts anticipate further momentum leading into the new year.
