Stocks rise to cap wild week on Wall Street

The major U.S. stock indexes finished the week on a positive note, taking back some losses but failing to entirely erase the week's declines

The major U.S. stock indexes finished the week on a positive note, taking back some losses but failing to entirely erase the week's declines.

The S&P 500 on Friday added 1% and the tech-focused Nasdaq Composite Index rose 0.9%. The Dow Jones Industrial Average jumped almost 500 points.

It was an upbeat end for a turbulent week for stocks amid broad concerns about the U.S. labor market and about whether Big Tech companies — responsible for much of the market's gains this year — will be able to justify their sizable investments in artificial intelligence.

Even with Friday's rally, the S&P 500 was down about 1.8% on the week. It's up about 12% on the year. The Nasdaq was similarly down 2.7% on the week and up 15% for the year.

Two major U.S. companies were crucial to the week's bumpy ride: Nvidia and Walmart.
