Online wealth management services offer a lower-cost, automated approach to personal investing that's challenging and transforming the existing financial advisory paradigm.
In fact, this shift is so seismic that four leaders among these "robo-advisors" have placed in this year's third annual CNBC Disruptor 50 list of companies shaking up their space: Personal Capital (No. 14) Motif (No. 23), Wealthfront (No. 34) and Betterment (No. 36).
Paladin Research & Registry has compiled a list of five ways these new, so-called robo-advisors differ from traditional brick-and-mortar financial advisory firms staffed by ... humans.
Robo-advisor definition: An online service provider that provides automated investment management with limited human contact.
Financial advisor definition: Located on Main Street in your city. Provides personal advice and services with an emphasis on human contact.
