US stocks have slipped backward as the promise of new Greek and Italian Governments failed to quell market contagion or point the way to a comprehensive eurozone crisis deal.

The Dow Jones Industrial Index finished the week down 2.9 per cent from the previous Friday, at 11,796.16.
But the S&P 500 and the Nasdaq Composite gave up more ground Friday with the S&P, at 1215.65, ending down 3.8 per cent for the week and the Nasdaq, at 2572.50, 4 per cent lower.
