‘Flash Boys’ Programmer in Goldman Case Prevails Second Time

Updated on

A former Goldman Sachs Group Inc. programmer who took the firm’s high frequency trading code when he left for another job was exonerated a second time after a judge ruled what he did wasn’t a crime.

Sergey Aleynikov, whose saga helped inspire Michael Lewis’s “Flash Boys,” was tried by New York prosecutors who took up the case after a federal conviction unraveled. His defense both times was that his actions were a disagreement between him and the bank better suited for civil litigation.
