U.S. stocks closed firmly lower on Tuesday, with the S&P 500 snapping a six-day winning streak, as investors focused on heightened tensions between the West and North Korea and worries about a lack of progress on President Donald Trump's pro-growth agenda.

Low trading volume, particularly as investors returned from a holiday-lengthened Labor Day weekend, added to the downbeat tone on Wall Street.

After four straight days of gains, the Dow Jones Industrial Average fell 234.25 points, or 1.1%, to finish at 21,753.31. The S&P 500 shed 18.70 points, or 0.8%, to close at 2,457.85, with eight of the large-cap index's sectors ending in the red.

The Nasdaq Composite Index declined 59.76 points, or 0.9%, to close at 6,375.57.

"People are getting a little more nervous on the margin--not just the geopolitical stuff--over whether tax reforms and pro-business policies will get done," said Ian Winer, head of the equities division at Wedbush Securities.

Investors are rotating out of sectors that would have benefited from deregulation, such as financials, and moving into bonds, according to Winer. "People today seem to feel that things won't get done or get watered down," he said.

Underlining Tuesday's run to haven assets and concerns about fiscal-policy progress, the 10-year benchmark (http://www.marketwatch.com/story/treasury-yields-slip-as-north-korea-triggers-demand-for-havens-2017-09-05) Treasury yield fell 9 basis points to 2.07%. Bond yields move inversely to prices.

"I didn't see a reason for us to go up as much as we did last week, so I think a big part of today's move is people taking profits off the table. To the extent that geopolitics are impacting the market, I think it will be in short-term back-and-forth movements," said Katrina Lamb, head of investment strategy and research at MV Financial.

"Valuations are expensive, but that doesn't mean things are automatically due for a pullback anytime soon. There hasn't been a major structural shift in the market, so I would encourage investors to keep an eye on things, but not to get too defensive."
