J.P. Morgan CEO Jamie Dimon has long joked that no matter when you ask him, he still has five years to retire. But he gave a different answer on Monday. In response to a question about how long he plans to be CEO, Dimon told shareholders that the timeline “is no longer five years.” On the company's Investor Day, he said the plan to succeed the nation's largest bank “is progressing smoothly.” After Damon, the question of who is in charge of the company looms over the industry. Dimon transferred some of his senior assistants to new senior positions earlier this year to give them more experience in managing the company as he prepares potential successors. “It's up to the board, not me,” Dimon said Monday. “I have the same energy as always. This is important. I think I should basically leave when I'm not ready and fully committed.”
