On the earnings front, Goldman Sachs ( GS ), Johnson & Johnson ( JNJ ) and Coca-Cola ( KO ) all reported better-than-expected profits pre-bell, with Coca-Cola establishing a new 52-week top of $42.32 in the process. U.S. stocks opened with a strong move to the upside in early dealings, recovering from yesterday's massive sell-off, exacerbated in late trading by news of the Boston Marathon terror attack. More good news on the domestic housing front and tame consumer inflation data, along with solid corporate earnings reports before the bell, have supported the move higher today.
