A promise by European leaders to help Greece avoid default sent stocks sharply higher Wednesday, the third day of gains in a row. The leaders of Greece, France and Germany agreed in a teleconference that Greece was an "integral" part of the 17-country bloc that uses the euro. Greece also said it would stick to agreements to trim its debts, a condition for getting more financial help. The statements were intended to calm fears that Greece was headed for a default on its debt or might be forced to drop the euro.
The threat of a Greek default and the damage it could wreak on financial markets has had investors on edge in the past two weeks.
