Investment philosophy championed by Vanguard founder John Bogle advocating low-cost, diversified index funds over active stock picking. Became dominant retail investing strategy of 2010s, accelerated by robo-advisors and commission-free trading.
Core Principles
Buy the entire market via total stock market index funds (e.g., VTSAX, VTI), minimize fees (expense ratios <0.1%), ignore market timing, rebalance annually, and hold for decades. “The only thing you can control is cost”—Bogle’s mantra. Three-fund portfolio (US stocks, international stocks, bonds) became default FIRE movement allocation.
Bogleheads Community
r/Bogleheads subreddit (2009) and Bogleheads.org forum became hubs for passive investing education. Community coined phrases like “stay the course” and “time in the market beats timing the market.” Jack Bogle’s death (Jan 2019) prompted tributes across financial media.
Market Impact
Index funds surpassed active funds in assets ($10T+) by 2019. Vanguard ETFs (VTI, VOO) became most-traded securities. Critics warned of “index bubble” concentration risk (top 10 stocks = 30%+ of S&P 500) and potential market distortions, but empirical evidence favored indexing for 80%+ of individual investors.
