Wall Street kicked off a busy week of corporate earnings with a broad rally Monday, the latest about-face for a market that has been unsteadily lurching between gains and losses in recent weeks.
The S&P 500 climbed 2.6 percent, more than recovering the ground it lost in a sell-off Friday. The Dow Jones Industrial Average rose 1.9 percent and the Nasdaq composite added 3.4 percent.
