If Republican presidential candidate Donald Trump wins the election, investors shouldn’t expect markets to react as harshly as they did to the U.K.’s Brexit referendum results, according to one Wells Fargo strategist.

Trump’s stances on foreign policy, trade and immigration have already unnerved financial markets leading up to the Nov. 8 election. But even though a victory by Trump would probably be to the downside, the overall impact on investors won’t be severe, Scott Wren, senior global equity strategist with the Wells Fargo Investment Institute, told BNN in an interview.

"I don't think it would be extreme,” Wren said. “I don't think it would be anything like the Brexit selloff and I do believe it would present a buying opportunity."

Global stocks are rallying a day before Americans hit the polls, after the FBI cleared Democratic presidential candidate Hillary Clinton of criminal charges related to her use of a private email server.

Wren said no matter who wins, investors won't be hung up on the results for too long.

"Whoever wins this election tomorrow, the market will soon move beyond that and to the outlook of what's going to be earnings and the economy — what the outlook is going to be over the next six to 12 months — very, very quickly," Wren said.

Regardless of which candidate becomes U.S. president, Wren said he sees buying opportunities in cyclical, industrial, consumer discretionary and tech sectors. But Wren also expects some other sectors to benefit if Trump wins.

"Certainly the energy sector as a whole, fossil fuels would benefit from that based on his projected policy," Wren said.

Wren also said he thinks a Trump presidency would likely lead to lower corporate tax rates, and therefore more companies repatriating money to the U.S.

This would benefit sectors such as tech, consumer staples and pharmaceuticals, he said: "Companies on those types of sectors that tend to do a lot of overseas business I think would benefit from that.”
