All three major U.S. stock indexes ended higher Monday, as Big Tech rallied. The Dow eked out a gain of less than 0.1% to notch its sixth record close of the year.

A quiet finish for U.S. stocks masked big swings underneath the surface. The S&P 500 rose 0.1% Tuesday after swinging between a gain of 0.5% and a loss of nearly 1%.

Stock futures were near the flatline in overnight trading after a tepid session for U.S. equities. Futures tied to the Dow Jones Industrial Average lost 32 points, or 0.06%. S&P 500 futures fell 0.07%, while Nasdaq 100 futures slipped 0.1%.

The Dow Jones Industrial Average earlier this month closed above 50000 for the first time, prompting one very enthusiastic fan—namely President Donald Trump—to project that the index would double by January 2029.

Dow falls more than 600 points; Nasdaq retreats 2%

The stock market continued what has been a turbulent period with another drop Feb. 12 attributed to concerns over AI, experts said.

The tech-heavy Nasdaq, benchmark S&P 500, and blue-chip Dow Jones Industrial Average pulled back 2%, 1.6%, and 1.3%, respectively, with the Dow shedding 670 points. It was the Dow's second straight decline following a three-session winning streak that brought daily intraday and closing records.
