U.S. stocks open lower after long weekend

U.S. stocks opened lower on Tuesday, the first trading day after a long weekend, as Wall Street shifted its focus from Brexit to the uncertainty over the timing of a next rate hike.

Shortly after the opening bell, the Dow Jones Industrial Average was down 84.37 points, or 0.47 percent, at 17,865.00. The S&P 500 lost 11.03 points, or 0.52 percent, at 2,091.92. The Nasdaq Composite Index shed 28.33 points, or 0.58 percent, at 4,834.24.

Investors will keep a close eye on Friday's nonfarm jobs report this week for more clues on the U.S. Federal Reserve's next rate hike.

"This week's highlight is the June employment report," said Chris Low, chief economist at FTN Financial.

New York Fed President William Dudley, a voting member of the Federal Open Market Committee, will speak on local economy later Tuesday at a roundtable discussion.
