US STOCKS SNAPSHOT-Wall St dips on Greek angst, but off lows

The Dow Jones industrial average fell 36.8 points, or 0.2 percent, to 18,126.19, the S&P 500 lost 2.6 points, or 0.12 percent, to 2,120.88 and the Nasdaq Composite dropped 8.62 points, or 0.17 percent, to 5,097.98.
The S&P had earlier fallen as much as 0.5 percent.
