The Dow Jones industrial average jumped back above 10,000 on hope that the European Union will help Greece manage its growing debt burden.
The Dow rose 150 points Tuesday, a day after closing below 10,000 for the first time in three months. The major indexes all gained more than 1 percent.
Global markets bounced back on reports that European Central Bank President Jean-Claude Trichet is changing his travel schedule to attend a meeting of EU officials on Thursday and that plans are being developed to rescue Greece. The reports are raising hopes that policymakers will take bigger steps to contain troubles in Greece. The county is struggling with big budget gaps and is seeing demand fall for its debt.
