Until a trade dispute between the US and China is resolved, a single tweet on the matter will have the power to ignite rallies and sell-offs.

The tweet in question this week is President Donald Trump’s declaration that “big progress” is being made towards a deal between the US and China, and it may spur gains across emerging markets. The message comes about 10 days before a US government delegation is said to be heading to Beijing for the first face-to-face discussion between the two sides since early December.

Investors will also be on alert when Federal Reserve chair Jerome Powell joins his predecessors for an interview on Friday as derivatives traders bet that the central bank will not hike interest rates in 2019. Some see the next move as a cut in 2020.

“Emerging markets have been particularly hard hit so I expect to see a relief bounce in January,” said Tarek Fadlallah, the Dubai-based CEO at Nomura Asset Management Middle East. “But where do we go after the relief bounce? I think nowhere. The reason why interest rates are not going up in the US is because the economy is not going to be very strong.”

Stocks, bonds and currencies across developing nations are poised for their worst annual performance in three years. The outlook for China’s economy is also key for developing-nation assets, Fadlallah said

The December purchasing manager index (PMI) for the manufacturing sector showed the first contraction since 2016 amid the threat of a prolonged trade war.

The manufacturing PMI dropped to 49.4 in December from 50.0 in November. The non-manufacturing PMI rose to 53.8 from 53.4, suggesting recent stimulus efforts may be starting to have some effect.
