The Jamie Dimon Dilemma: JP Morgan's Leadership Challenge.

The question of who will succeed Jamie Dimon as CEO of JPMorgan Chase is gaining urgency as the bank increases its hold over the rest of the industry. While the 67-year-old Dimon has made it clear he has no near-term plans to leave, the list of candidates to replace him includes longtime JPMorgan executive Daniel Pinto, who could step in if something went wrong suddenly, and two consumer-banking bosses, Marianne Lake and Jennifer Piepszak, who are considered frontrunners if Dimon stays another three to five years.
