Wall Street rises as Dec 15 tariff deadline looms

Wall Street eked out slight gains on Thursday as investors waited for concrete news on a hoped-for interim trade deal between the United States and China before a new round of tariffs scheduled to kick in on Dec. 15.

Tech stocks led all three major US stock averages marginally into the black following upbeat statements from President Donald Trump and Treasury Secretary Steven Mnuchin that the US-China trade negotiations are "on track" and "going well."

Markets have been whipsawed in recent days by conflicting reports on whether the world's two largest economies would be able to arrive at a "phase one" agreement prior to Dec. 15, when a new round of tariffs on Chinese imports is expected to take effect.

"Investors are trying to calibrate things," said Matthew Keator, managing partner in the Keator Group, a wealth management firm in Lenox, Massachusetts. "The markets are going to toggle up and down until we see what happens on Dec. 15th to get some sort of clarity in terms of how to move forward in the near term."

Market participants appeared to shrug off the drama unfolding in Washington as the US House of Representatives prepared to draft articles of impeachment against President Donald Trump.

"The market has become desensitized a bit to the partisanship that's been going on," said Keator, while adding that "uncertainty is not something the market enjoys."
