Assets managed by Internet-age advisers are a tiny but fast-growing piece of the $18 trillion wealth-management market, which encompasses everything from the newest online advisers to old-school brokerage firms, according to Aite Group, a Boston research firm. Digital wealth-management assets, which include those managed by robo advisers as well as traditional firms with online offerings, are projected by Aite to reach $55 billion to $60 billion this year, up from $16 billion at the end of 2014.
