A pledge by European leaders to head off a Greek debt default helped investors push U.S. stocks higher, as the market's sovereign-debt jitters eased notably today. Stocks found their footing as European Union leaders expressed confidence at a meeting in Luxembourg that Greece will concede on economic reforms in order to release the next installment of aid, avoiding a default. The action follows the end of a six-week losing streak for U.S. stocks on Friday. The losing streak has left the Nasdaq Composite in negative territory for the year and sapped other major indexes of much of this year's advance. DJIA +76.02 Nasdaq +13.18 S&P 500 +6.86.
