(Reuters) - U.S. stocks fell on Tuesday, pushing the S&P 500 to its biggest percentage drop in three weeks on Tuesday, weighed down by concerns about Greece's financial crisis and some upbeat U.S. economic data that fuelled expectations a rate hike could come sooner rather than later.
The Dow Jones industrial average fell 188.95 points, or 1.04 percent, to 18,043.07, the S&P 500 lost 21.79 points, or 1.02 percent, to 2,104.27 and the Nasdaq Composite dropped 56.61 points, or 1.11 percent, to 5,032.75.
