U.S. stocks fell slightly on Wednesday as investors anxiously await the Federal Reserve’s January statement. While investors aren't expecting a second rate hike, they are eager to hear how the Fed comments on the recent spat of volatility throughout the markets. 'The market volatility that we're seeing at the moment and the big swings in China and oil prices – these are the very reasons that the Fed didn't raise in September when we all expected them to, so it'll be interesting to see what they [think] this is going to do to the policy going forward,’ said James Hughes, chief market analyst at GKFX, based in London. Meanwhile, Boeing (BA) reported earnings of $1.60 a share for its fourth quarter, beating estimates of $1.28. Revenue slightly exceeded expectations. Its 2016 guidance was lower than expected amid lower sales from the defense and space areas. Plus, United Technologies (UTX) posted earnings of $1.53 a share, a penny ahead of estimates.
