By Stephen Culp NEW YORK, April 13 (Reuters) - Wall Street headed higher on Wednesday, powered by a rebound in market-leading growth stocks as investors digested hot inflation data and a mixed bag of quarterly earnings. On Thursday, the holiday-shortened week will end with results from a swath of big banks, including Morgan Stanley MS.N, Citigroup Inc C.N, Goldman Sachs Group Inc GS.N, and Wells Fargo & Co WFC.N. JPMorgan Chase & Co JPM.N set the first-quarter earnings season off to an inauspicious start, reporting a 42% drop in quarterly profit.
