Symantec (SYMC) stock plunged 33% on Friday on the news. KPMG has come under criticism because it is also the accountant for two blue-chip companies with major financial headaches — GE (GE) and Wells Fargo (WFC). At least 15 Wall Street analysts had cut their price targets on Symantec by Friday morning, according to FactSet. News of the investigation erased all the gains Symantec stock had made in the past few years. Fortunately for consumers, there was no indication that Symantec's investigation had to do with the integrity of its products.
