One of the investment world’s best-known figures, Mohamed El-Erian announced his resignation as CEO of trillion dollar bond giant Pimco last month. El-Erian gave no reason for his departure, which is scheduled for March. He will, however, stay on as a consultant at Pimco’s parent company, Allianz. El-Erian, 55, remains a well-known commentator on the broadcast media circuit. While his next move is unconfirmed, it’s likely to be highly influential. His book, When Markets Collide, was named one of the best business books of all time by The Independent.
