Vanguard invests both time and money to remain at the forefront of the investment community. The Vanguard Group offers individual and institutional investors a comprehensive line of mutual funds and brokerage services. Boasting more than $3 trillion of assets under management, including some $455 billion in exchange-traded fund (ETF) assets, the firm is battling rival FMR (better known as Fidelity Investments) for the title of largest retail mutual fund manager worldwide. Vanguard's fund options include approximately 280 stock, bond, mixed, and international offerings, as well as variable annuity portfolios. Known for its low-cost mutual funds, Vanguard was founded in 1975 by investment guru John C. Bogle.
