U.S. stocks edge higher on Greece hope

U.S stocks edged higher on Tuesday as investors were expecting a deal for Greece to secure a new bailout. The CBOE Volatility Index, widely considered the best gauge of market fear, closed below 18. The Greek government was working out further austerity measures required by its international lenders as part of conditions for a second bailout. And the country\' s talks with private creditor on debt reduction were also on the way. The rescue plan is crucial for Greece as the country faces a potentially devastating default in March when large payments of debt fall due. U.S. Stocks reversed their earlier losses as the efforts by the Greek government to avoid such default helped to ease investors concerns. Meanwhile, Ben Bernanke, the Chairman of the Federal Reserve, reiterated his view on the U.S. economic prospect during his testimony to Congress on Tuesday, which was seen by traders as a confirmation of a continued policy of ultra low interest rate for at least another two years.
