Wall Street roared back Tuesday as crude oil prices bounced higher and several companies reported strong earnings. The Dow closed up better than 1.75 percent. Oil rose on hopes for a deal among oil producers to reduce the current supply glut, lifting major oil producers like Exxon (XOM) and Chevron (CVX). Several Dow names reported earnings including 3M (MMM), Procter & Gamble (PG), and Johnson & Johnson (JNJ). Both J&J and Procter & Gamble posted strong earnings, even as the stronger dollar weighed on sales. 3M moved higher as results beat expectations, and Sprint (S) also rose as its loss was not as bad as some analysts had expected, and the company said that revenue had stabilized.
