STRONG START: Stocks had their biggest gains in more than two weeks Monday after European officials promised to take action to resolve the region's debt problems. The Dow Jones industrial average jumped 272 points.
THE PLEDGE: Leaders met in Washington this weekend and pledged to take bolder steps to fight Europe's debt crisis, which threatens to slow the global economy.
WINNERS: Financial stocks had the biggest gains in the S&P 500. Banks have the most to lose if Europe's debt crisis gets worse, so investors picked up those stocks as hopes built that a resolution could be on the way.
