US EditionWall St Ends Higher as Tech Rally Continues, Led by Micron
Micron's record highs and Nvidia's chip export review fueled a tech-led rally lifting the S&P 500 by 0.9%, amid expectations of Fed rate cuts and seasonal strength.
- On Dec 19, Micron Technology reached a record closing high, ending the day up 7%, while U.S. stock markets rose as technology shares rebounded, offsetting tumbles in consumer stocks such as Nike.
- Megacaps extended gains from Thursday, when Micron Technology's strong forecasts re-ignited optimism around AI-related companies that had recently faced pressure over valuations.
- Major indexes rose, with the Dow Jones Industrial Average up 183.04 points, the S&P 500 gaining 0.88%, and the Nasdaq Composite rising 1.31%, while the NYSE showed 269 new highs and 72 new lows.
- Traders continued to bet on at least two 25-basis-point rate cuts next year, while analysts warned triple witching and options expiration could raise volatility.
- December's seasonal strength and regulatory moves, like a U.S. review of Nvidia chips and ByteDance's TikTok deal, shape megacap outlooks.
