U.S. stock index futures pointed to a slightly higher open Wednesday, as investors prepare themselves for a deluge of news out of the political and economic spheres.
Ahead of this, political parties are in their final stretch of campaigning on Wednesday, with each group hoping to secure a significant number of parliamentary seats in the election.
In the U.S., the former FBI director James Comey is expected to testify on Thursday in front of the Senate Intelligence Committee, marking his first public comment since being dismissed by the U.S. president.
Thursday will also mark the European Central Bank's latest monetary policy meeting, where investors will be examining President Mario Draghi's rhetoric, when it comes to the future of ECB policy.
Meanwhile, consumer credit is slated to come out at 3 p.m. ET. Also, mortgage applications rose 7.1 percent last week as rates hit their lowest levels since the election.
In the commodities sphere, crude futures were under pressure as investors remained on edge over concerns of a glut in the market. U.S. crude and Brent were both lower at 8:12 a.m. ET Wednesday, trading at $47.88 and $49.74 per barrel respectively.
