Salomon Smith Barney powerbroker analyst Jack Grubman, a close friend of former WorldCom chief executive Bernard Ebbers, said he was shocked by news of WorldCom's $4bn (£2.7bn) fraud, though two days ago he cut his rating on the firm to 'underperform' from 'neutral'. 'Nobody saw this coming, I'm no different than anyone on Wall Street,' said Grubman, a one-time boxer who rose from a blue-collar neighbourhood in Philadelphia to Wall Street's top echelon. Now he and other analysts are fighting to salvage their reputations as questions swirl about how they could have been so blind to financial high-jinks at companies such as Enron, Global Crossing and WorldCom.
