By Lewis Krauskopf NEW YORK (Reuters) - The yen lost ground against the U.S. dollar on Thursday amid speculation Japan could expand its monetary stimulus soon, while a drop in Apple shares dragged the Nasdaq lower in a volatile trading day. Oil prices settled higher after a roller-coaster session that saw U.S. crude touch a six-month high. U.S. Treasury prices fell after comments from a Federal Reserve official suggested interest rates could rise faster than some investors expect.
