Stock prices fall on worries over Greece

Stock prices plummeted in Europe and stock futures were down in the US after EU ministers failed to expand a bailout fund to help Greece. Bank stock prices led the decline in Europe.

U.S. stock index futures fell sharply Monday as renewed fears of a Greek debt default prompted investors to book some of last week's gains and turn to safer assets such as gold.

At meetings Saturday, European Union finance ministers broke no new ground in dealing with the crisis and made no decision on whether to give more firepower to the 440 billion euro ($607 billion) bailout fund, as suggested by U.S. Treasury Secretary Timothy Geithner.

Investors' risk aversion also rose after the Greek prime minister, George Papandreou, canceled a visit to the United States to instead chair a cabinet meeting Sunday, a day before EU and International Monetary Fund inspectors hold a conference call with Finance Minister Evangelos Venizelos to hear how Greece will plug this year's budget shortfall.

``Uncertainty is still the prevailing theme on Wall Street.''

A regional election defeat for German Chancellor Angela Merkel Sunday, her sixth election defeat this year, also kept investors on edge.
