One investor urged others to "take a step back" for now amid the market volatility in the past week.
"Take the money off the table, sit on the sideline ... let the picture clear up a bit and i think you will get a better sense of where (these) markets are headed," Haren Shah, managing director and head of investments at Taurus Wealth Advisors, told CNBC's "Street Signs" on Thursday.
"By the way, you see the tariffs we're doing? Because they broke the deal. They broke the deal," Trump said. "So they're flying in, the vice premier tomorrow is flying in — good man — but they broke the deal. They can't do that, so they'll be paying."
But one analyst expressed concern.
"We are not sure who the president is addressing tonight in a campaign rally, but he is sure scaring the daylights out of the financial markets," Chris Rupkey, managing director and chief financial economist at global financial group MUFG, wrote in a note following Trump's speech.
"One thing is certain, if the U.S. raises tariffs on the last $200 billion of imports from China from 10% to 25% then this spells disaster for the U.S. economy," Rupkey said. "We have never been so close to recession's door simply based on the policies from Washington."
Markets have been rattled for much of this week after Trump said in a Twitter post Sunday that the U.S. would raise tariffs on Chinese goods as soon as Friday, a move that was unexpected by investors who had priced in the possibility of a trade deal being reached between the two economic powerhouses.
The U.S. dollar index, which tracks the greenback against a basket of its peers, was at 97.532 after an earlier high of 97.636.

In overnight market action on Wall Street, stocks finished the trading day largely unchanged. The Dow Jones Industrial Average jumped midday after the White House confirmed President Donald Trump's tweet earlier that Chinese Vice Premier Liu He will be leading a delegation to Washington this week for trade negotiations.
"That uncertainty remains and it's a long way from the expectation of recently as a week ago that the two sides had almost agreed on the document and this week more a formality rather than another meaty round of negotiations," David de Garis, a director and senior economist at National Australia Bank, wrote in a morning note. "It's still not done and it could easily go pear-shaped again."
