U.S. Stocks Open Slightly Lower As Geopolitical Uncertainties Weigh

U.S. stocks traded modestly lower on Tuesday, as investors found few reasons to keep pushing shares higher with major indexes near records and as multiple geopolitical concerns weighed on sentiment. The Dow Jones Industrial Average fell 54 points, or 0.3%, to 21,130. The S&P 500 lost 6 points to 2,430, a decline of 0.2%. The Nasdaq Composite Index lost 14 points, or 0.2%, to 6,282. Trading could be tepid until Thursday, when former Federal Bureau of Investigation boss James Comey will testify to a Senate panel about Russian efforts to interfere in last year's presidential race. An upcoming announcement by the European Central Bank and an election in the United Kingdom could also drive trading in coming days. Among the day's biggest movers, Michaels Cos. fell 3.3% after it reported earnings that missed expectations and lowered its outlook.
