U.S. stock index futures were little changed on Wednesday ahead of President-elect Donald Trump's first formal news conference where he is expected to give more insight into his plans to boost economic growth.
Trump, who takes office on Jan. 20, is scheduled to speak in New York at 11:00 a.m. ET (1600 GMT).
Trump's election in November sparked a record-setting rally, but investors now want evidence on whether he keeps his campaign-trail promises to stimulate the economy through increased public spending, tax cuts and the repatriation of U.S. companies' funds from overseas.
The dollar .DXY, which has also basked in Trump's victory, was up against the yen. However, concerns of some of his protectionist statements have kept investors wary.
Keeping futures afloat were oil prices, which edged up for the first time in three days after Saudi Arabia provided details of a February supply cut to some of its Asian customers. [O/R]
