Marta Ortega

Ortega landed the top job at the $33-billion-in-revenue fashion giant last April. But as the youngest daughter of Inditex’s founder, she’s been steeped since birth in the company, best known for its Zara brand. Just 38, Ortega was touted by execs as part of a long-expected “generational succession process.” Even so, Inditex’s stock plunged 6% on the news, as investors wondered whether she has the skills to maintain Zara’s dizzying growth.
