JPMorgan's Alejandro Vicente, a managing director in consumer goods, is the latest to make the jump.

He's leaving to work for JAB Holdings, the Keurig and Caribou Coffee owner that last week announced it was buying Krispy Kreme, the Financial Times'Arash Massoudi reports.

Vicente will be working on transactions for the company, which has been on a buying spree lately and also owns stakes in a number of consumer-products brands.

But he's not the only one. Earlier this year, former Morgan Stanley banker Alban de La Sabliere joined the French drug maker Sanofi, which is now bidding to buy the pharmaceutical company Medivation.
