Wall Street stocks mixed as Trump withdraw the US from Iran deal

• The US leaving the Iran deal can lead to geopolitical uncertainties.
• US stocks are trading slightly higher on the day as markets seem not worried by the news.

The S&P 500 Index closed slightly lower at 2,671.92 down 0.1%, while the Dow Jones Industrial Average closed higher 0.1% at 24,360.21. The tech-heavy Nasdaq Composite Index ended the day virtually unchanged at 7,266.90 up less than 0.1%.

Stocks traded mainly sideways after Trump announced that he was withdrawing the US from the Joint Comprehensive Plan of Action (Iran nuclear deal). The decision can lead to a more complex geopolitical environment as China and Russia are also part of the deal. There are already diplomatic tensions with those two countries and adding now the Iran nuclear issue is likely going to compound the tensions.  

Treasury Secretary Steven Mnuchin tried to calm fears: "President Trump has been consistent and clear that this Administration is resolved to addressing the totality of Iran's destabilizing activities. We will continue to work with our allies to build an agreement that is truly in the best interest of our long-term national security." He also said that the sanctions will be subject to 90 and 180-day wind-down periods.
