Just a few days before Father's Day 2015, Money assistant managing editor Pat Regnier interviewed John C. "Jack" Bogle, the founder and former CEO of Vanguard, the world's largest mutual fund company. The elder statesman of the mutual fund industry—and a pioneer in index investing—talked about the investing advice he gives his children, one of whom runs a hedge fund, along with how he invests, and doesn't invest, on behalf of his grandchildren. Look for an in-depth interview with Bogle in an upcoming issue of Money.
