Bernanke Speech to Set Market.

Fed Chairman Ben Bernanke speaks on the economy and policy, at a time when both are shaky in the eyes of the markets. Bernanke's Friday morning address in Jackson Hole, Wyo. has become one of the most discussed, debated and dissected of his career, even before he's given it. "He's going to need a miracle to satisfy all these multiple expectations that are all over the place," said Art Cashin, director of floor operations at UBS. It is hoped that Bernanke will clarify two things - how bad the Fed believes the economy is getting and what it might do about it.Link
