NEW YORK, Jan 27 (Reuters) - U.S. stocks fell on Wednesday after data showed new home sales dropped unexpectedly in December, as investors remained wary ahead of the U.S. president's State of the Union speech and the end of the Federal Reserve policy meeting.
President Barack Obama, in his first State of the Union address, is expected to promise more jobs creation and a slimmed budget deficit. Fed policymakers will issue a statement that may give clues on how long the Fed will keep in place ultra-low interest rates and its easy-money program. For details, see [ID:nN26106537] and[ID:nOBAMA]
New home sales fell for the second straight month, according to the Commerce Department, while analysts expected a rise. [ID:nN26112107]
Caterpillar posted stronger-than-expected earnings but forecast 2010 profit below expectations, while United Tech posted a 6 percent drop in quarterly profit and its finance chief warned of a "tough" first quarter. [ID:nN27163192]
"The home sales data wasn't good, and coming on top of some bad outlooks, is pressuring the market," said Dan Cook, senior market analyst at IG Markets in Chicago. "However, we're not down as much as we could have been since no one is going to make too big of a commitment before the Fed meeting and Obama's speech."
The Dow Jones industrial average .DJI fell 36.57 points, or 0.37 percent, to 10,155.51. The Standard & Poor's 500 Index .SPX dropped 3.85 points, or 0.39 percent, to 1,087.94. The Nasdaq Composite Index. .IXIC lost 3.01 points, or 0.14 percent, to 2,200.77.
Boeing Co (BA.N) was the Dow's top boost, rising 2.8 percent to $59.30 after reporting that it swung to a quarterly profit as revenues soared 42 percent. [ID:nN26103777]
Losses in the Nasdaq were limited by better-than-expected results from Gilead Sciences Inc (GILD.O) and Yahoo Inc YHOO.O, both of which reported late Tuesday. Gilead gained 6.1 percent to $47.63, while Yahoo climbed 1 percent to $16.17. [ID:nN26120092] and [ID:nN2519773] (Editing by Jeffrey Benkoe)
