Nasdaq drops 1% Friday as Nvidia tumbles, Dow closes out worst week since October: Live updates
Stocks retreated on Friday, closing out a turbulent week as Nvidia 's incredible run took a breather.

The S&P 500 lost 0.65% to 5,123.69, while the Nasdaq Composite slipped 1.16% to 16,085.11. Both swung into negative territory after rising to new all-time highs earlier in the session. The Dow Jones Industrial Average relinquished 68.66 points, or 0.18%, to end at 38,722.69.

All three major indexes finished the choppy week lower. The broad S&P 500 pulled back by 0.26% this week, while the blue-chip Dow and tech-heavy Nasdaq fell 0.93% and 1.17%, respectively. That decline marked the worst week for the 30-stock Dow since October.

Stocks were hurt Friday as an earlier rally in Nvidia lost steam. The artificial intelligence darling finished down more than 5% in its worst session since late May.

Despite that breather, Nvidia shares still finished up more than 6% on the week. It's part of a monster rally that has added more than $1 trillion to the stock's market cap in just the new year alone.

"It doesn't mean that the longer-term upside potential is over," said Sam Stovall, chief investment strategist at CFRA Research, of Nvidia's Friday move. "It just says that maybe we've gotten ahead of ourselves: We've gotten to an overbought situation, and it's time to take some profits."
