U.S. equities fell on Tuesday as investors fretted over geopolitical concerns, pushing safe-haven assets higher.
The Dow Jones industrial average slipped less than 10 points after dropping more than 100 points, with Apple contributing the most losses. Apple was hit by a countersuit from chipmaker Qualcomm in a dispute over mobile technology licensing fees.
"Equities have been ignoring geopolitical concerns over the past week, but now things are heating up and investors are preparing for some volatility," said Ryan Detrick, senior market strategist at LPL Financial.
The S&P 500 pulled back about 0.1 percent, with financials and information technology leading decliners. The Nasdaq composite declined 0.2 percent as tech stocks declined for an eighth straight session.
The Dow transports were also under pressure, as shares of United Continental briefly pulled back more than 4 percent outrage over a passenger being dragged off an overbooked flight finally caught up to the stock.
"There are a number of things that have traders concerned. First, the geopolitical circumstances. Second, if Congress doesn't move quickly, the government will shut down," said JJ Kinahan, chief market strategist at TD Ameritrade.
Equities cut losses after President Donald Trump told a group of executives that his administration was looking to revamp Dodd-Frank, which might be eliminated and replaced with "something else."
