Stocks fell sharply on Friday after weaker-than-expected data in China and Europe exacerbated concerns of a global economic slowdown.

The Dow Jones Industrial Average fell 460 points, led lower by declines in Apple and Johnson & Johnson. The S&P 500 dropped 1.1 percent as the tech and health care sectors lagged. The Nasdaq Composite pulled back 1.1 percent.

Stocks initially surged this week amid hopes the U.S. and China would be able to strike a permanent deal on trade.

But the uncertainty around the ongoing negotiations has kept investors on edge recently. Data from research service Lipper found that more than $46 billion were pulled out in a week from U.S. stock mutual funds and ETFs, the most ever.
