Amazon ($AMZN) up 7% and Microsoft ($MSFT) up 5% during intraday trading

Amazon ($AMZN) and Microsoft ($MSFT) rose 7% and 5% intraday, respectively, during the December 4 U.S. trading session, according to 24/7 Wall St. At the same time, the S&P 500 gained 1.8%, the Dow Jones Industrial Average rose 2.1%, and the Nasdaq Composite climbed 2.4%, the steepest gain among the three indexes, per AP. Semiconductor stocks diverged, with Nvidia ($NVDA) declining while AMD advanced. The moves matter because they signal broad-based buying across mega-cap technology and the wider market, even as chip names split. Intraday figures should be distinguished from closing changes, and the next thing to watch is whether these gains hold through the close.
