A sign for Wall St. is displayed in front of the New York Stock Exchange (NYSE) stands in this photo taken with a tilt-shift lens in New York, U.S., on Friday, Oct. 19, 2012. U.S. stocks fell, trimming the biggest weekly advance for the Standard &amp;amp; Poor's 500 Index in a month, as Microsoft Corp. and General Electric Co. (GE) posted sales that missed estimates and euro-area leaders agreed on a banking regulation timetable. Photographer: Scott Eells/Bloomberg Photo: Scott Eells, Bloomberg
