Summary Box: Market rises to 2010 highs before erasing gains on concern about Greece bailout

Summary Box: Stocks give up gains on Greece woes

WHAT GOES UP: Major stock indexes rose to new highs for 2010 but gave up their gains Thursday after European Central Bank President Jean-Claude Trichet criticized a financial bailout for Greece.

SEEKING SAFETY: The comments hit the euro and boosted demand for the dollar. The higher dollar hurt shares of energy and materials companies because a stronger dollar hurts commodities.

TREASURYS STAY WEAK: Demand fell at a third straight Treasury Department bond auction. Unease grew that the government will be forced to raise interest rates to attract buyers. That could hurt the economy.
