NEW YORK ( TheStreet) -- State Street ( STT) is leading a surge among trust banks on Wednesday morning after saying it would far exceed the Street consensus in its second-quarter earnings. State Street shares were up 10% in Tuesday morning trading, and other big U.S. trust banks were lifted by the State Street bullish report on revenue growth. State Street expects earnings of 93 cents a share, excluding one-time charges, versus a Street estimate of 72 cents earnings from the Boston-based trust bank. The State Street full earnings report is set for July 20. Northern Trust ( NTRS) and Bank of New York Mellon ( BK) were up more than 4% after the State Street report. The State Street earnings surprise was helping to lift the U.S. market on Wednesday morning and forecast a bullish earnings season for banks. -- Written by Eric Rosenbaum from New York.
