By Stephen Culp NEW YORK, April 27 (Reuters) - U.S. stocks bounced higher and Treasury yields resumed their climb on Thursday as market participants digested solid earnings and signs of a dampening economy. Treasury yields gained ground across the board as investors weighed the looming debt ceiling showdown in Washington and signs that inflation could remain stubbornly high even as the economy slows. The greenback advanced against a basket of world currencies following the weaker-than-expected GDP report, which did little to affect financial markets' bets on another rate hike at the Fed's policy meeting next week.
