Sanctions, tariffs and earnings headline the week ahead

On Tuesday just after midnight U.S. Eastern time, the Trump administration will bring back a series of sanctions against Iran that had been waived under the Iran nuclear deal.

It was an Obama-era agreement that gave Iran sanctions relief in exchange for curbs on its nuclear program.

In May 2018 President Trump announces that he was backing out of the Iran Nuclear Deal.

This will just be the first wave with the remainder reimposed in November.

Trade tensions will continue to weigh on investors' minds.
