Investors might selloff Chinese artificial intelligence equities as the U.S. and China have not finalized any concrete deals during President Donald Trump's two-day visit to Beijing, especially on the importation of chips, Jefferies said in a research note on Monday.

Jefferies said there was hype over Nvidia Chief Executive Officer Jensen Huang being included in Trump's delegates in a last-minute decision, as talks could involve semiconductor exports to China. However, the trip only laid the groundwork for actual deals that would be formulated in the next three to six months, according to the note.

China agreed to the purchase of certain U.S. products, which could only be a part of the deals, Jefferies said.

China pledged to buy 200 Boeing airplanes, $17 billion worth of U.S. agricultural products until 2028, and the purchase of U.S. beef and poultry products.

Jefferies also said that the Board of Trade that the U.S. and China would establish will only tackle less sensitive investment issues, such as Contemporary Amperex Technology's (SHE:300750, HKG:3750) potential investment to construct a U.S. battery plant, but not lifting the U.S. investment ban on some Chinese companies.
