U.S. stock index futures indicated a higher open on Thursday as traders looked to Friday's key employment report and reacted to comments on Wednesday from Fed Chair Janet Yellen, who reiterated the possibility of raising rates in December, given supportive data.
Another key central bank leader, New York Fed President William Dudley, separately told reporters Wednesday that he would "completely agree" with Yellen on a December hike.
While more Fed speakers are scheduled for Thursday — including Fed Vice Chair Stanley Fischer, the Philadelphia Fed's Patrick Harker and the Atlanta Fed President Dennis Lockhart — analysts said Yellen's comments and the forthcoming jobs report are most important.
