The Dow Jones Industrial Average (DJINDICES:^DJI) is down 136 points to 15,791 at 1:30 p.m. EST on poor earnings news from Boeing (NYSE:BA). Along with shaky earnings reports, the her big news is the release of the Federal Open Market Committee statement today at 2 p.m. EST. The Fed is expected to announce an additional $10 billion per month taper of its asset purchases, which would bring the monthly bond buys to $65 billion.

The big mover pulling the Dow down today is Boeing, which is down 5.5% ($7.51) to $129.57. Boeing's large size and large drop accounts for nearly 40% of the Dow's loss today. In what seems to be a trend this quarter, Boeing reported earnings that beat analyst expectations but missed on guidance expectations. The aircraft maker reported earnings per share of $1.61, better than last year's $1.28 and better than analyst expectations of $1.57. Boeing stockholders had a banner year in 2013: the company delivered 648 aircraft, the stock rose 84%, the quarterly dividend was boosted nearly 50% to $0.73 per share, and Boeing announced an additional $10 billion share buyback authorization.

This year might not be as rosy. Boeing expects earnings per share in 2014 between $7.00 and $7.20, below analyst expectations of $7.57. The company also anticipates 2014 revenue of between $87.5 billion and $90.5 billion, below analyst expectations of $92.72 billion.
