The Chinese government should add more stimulus to its economy in one fell swoop, instead of doing it in spurts, Scott Brown of Raymond James said Wednesday.
"The Chinese currency has a lot of downward pressure on it now. They're likely to see some move for depreciation by the central bank there," he told CNBC's "Squawk on the Street." "But it won't happen all at once. That might not be a good thing. If they did it all at once they could get it out of the way. It will be a major concern for investors off and on."
The yuan hit a record low against the dollar Wednesday.
China's economic troubles took center stage once again this week, after weaker-than-expected manufacturing data caused financial markets around the globe to fluctuate.
Markets are also weighing claims from the North Korean government that it has successfully tested a nuclear bomb.
U.S. equities kicked off 2016 on the wrong foot, as the three major indexes have shed more than 2 percent. Overseas, the Shanghai composite has tumbled 5 percent, while the pan-European STOXX 600 index is 3 percent lower for the year.
Still, employment data in the United States remains strong. ADP said Wednesday that private firms in the U.S. added 257,000 jobs in December, handily beating a consensus estimate of 192,000.
This disconnect between positive U.S. data and geopolitical concerns should be watched by investors, but not to the extent that they alter their long-term strategies, Brian Jacobsen, chief portfolio strategist at Wells Fargo Advantage Funds, said in the same interview.
"You saw this interesting confluence last night with the release of the slightly weak service sector PMI out of China, about the same time that they depreciated their currency and also the news out of North Korea," Jacobsen said.
However, he advised investors to look outside of the U.S. for profits.
"You don't have the backdrop of incredibly accommodative monetary policy. Now it's just accommodative. There's a bit more risk around that earnings outlook," Jacobsen said.
"When you combine the taking away of the support of the central bank a bit here, along with the risk to the earnings outlook, I'm not expecting a lot of multiple expansion in the United States."
