U.S. stock index futures were higher on Monday, the last day of September, as investors watched trade developments between the U.S. and China.

Around 7:15 a.m. ET, Dow Jones Industrial Average futures indicated a gain of 54.75 points at the open. S&P 500 and Nasdaq 100 futures also traded higher.

Wall Street ended lower last week on reports that the White House is considering limiting U.S. investment into China, including a possible de-listing of Chinese companies from U.S. exchanges, in a further escalation of the ongoing trade dispute between the world’s two largest economies. However, spokespeople had denied that the U.S. was considering such a move.

U.S. and China trade delegations are due to meet on Oct. 10 as both sides try to move closer to a deal. Both countries have slapped tariffs on billion of dollars worth of their goods, dampening expectations for economic and corporate profit growth.

The major indexes were headed for a mixed monthly performance. The Nasdaq Composite was down slightly for September entering Monday’s session while the S&P 500 and Dow were up more than 1%.

On the data front, Chicago PMI figures for September are due at 8:45 a.m. ET and Dallas Fed manufacturing index data will be published at 9:30 a.m. ET.
