Investopedia explains 'John Bogle'
John Bogle is considered the Godfather of Index investing, believing that the average investor cannot "beat the market" over time, and shouldn't pay (or at least overpay) for anyone else to try. His Vanguard funds are renowned for their ultra-low expense ratios, and for having no loads. The Vanguard 500 Fund carries a total expense ratio of less than 0.5% of assets annually, and has outperformed the majority of mutual funds over the past 25 years.
