U.K.'s Prime Minister Theresa May announced on Friday that she would resign as party leader on June 7, paving the path for a new prime minister to continue Brexit negotiations with the EU.

What's one thing Wall Street investors should keep in mind amid the new announcement?

Action Alerts PLUS' Jeff Marks said turmoil in the U.K. gives investors another reason to look at the U.S. market. 

"I would say that if you're looking for a country to invest in, why not invest in the United States? And I'm not just saying that just because, if you look at how our markets are structured, it's the most transparent. It's deregulated in the right areas, regulated in the right areas," Marks said.

Marks added,"While what's going over there, maybe there's just a lot of chaotic and uncertainty and you know, we have our own uncertainty over here, but I still think the United States is, over the longer-term, is the right place to put your money."

Theresa May's departure puts Britain's Brexit process into uncharted territory, and raises the question for lawmakers whether or not the country can leave the European Union before the recently-extended October 31 deadline.
