Abigail Johnson

The world of investment management is changing, and Johnson wants to ensure that Fidelity—the nation’s second-largest fund manager, with $2.1 trillion in assets under management—is changing with it. While the company is famous for its stock ­picking (76% of its U.S. stock funds outperformed their peers in 2015), these pricey funds are falling out of favor; investors pulled $18.8 billion from Fidelity’s actively managed equity portfolios last year. So Johnson is slashing fees on Fidelity’s passive funds and targeting a fresh generation of customers with digital tools.
