Chammah blow is Mack setback

Let’s hope John Mack is not too downhearted at his failure to lure his old friend Walid Chammah away from Morgan Stanley. It would appear to be the first setback the chief executive of CSFB has had since replacing Allen Wheat last July.

Instead, he should be looking at it as marking a refreshing change in the fortunes of the investment bank: usually it’s CSFB’s executives who have to spend days convincing bankers not to leave, accompanied by the liberal use of the company cheque book.
