With the massive economic uncertainty being brought on by the aftermath of Brexit, many investors are unsure of where to put their money, and whether it is safe to invest in the global market.
Friday on CNBC's"Power Lunch," Marc Harris, head of global research at RBC, said that the uncertainty is the biggest problem currently facing the U.K and Europe.
"The sheer uncertainty about the process by which the U.K. will leave the E.U. is a dominant factor in assessing the economic outlook. We now forecast 0 percent GDP growth [U.K.]…Although automatic stabilizers in the government sector are likely to be allowed to operate naturally, neither that nor the boon from the exchange rate are expected to offset the drop in business spending or a moderation in private consumption growth."

Despite this global uncertainty RBC has released its updated list of "Top 30 Global Ideas" for the second half of the year, which includes the names of U.S. stocks, as well as some U.K. based companies like Royal Dutch Shell, Lloyds Banking Group PLC, and Dixons Car Phone.
Harris said these were three companies that have undergone a strong transformation through efficiency, growth, and M&A integration.
