Twice in the past 100 days, JPMorgan Chase & Co. Chief Executive Officer Jamie Dimon has turned to a 41-year-old former hedge-fund trader to tackle challenges facing the largest U.S. bank.
Matt Zames, named chief investment officer in May to contain trading losses that have cost at least $5.8 billion, became the firm’s co-chief operating officer last week.
