John Bogle was the founder of Vanguard and is best known for pioneering the index fund — a revolutionary approach that allowed everyday investors to buy low-cost, diversified exposure to the entire stock market. His philosophy emphasized broad diversification, low fees, and long-term investing through passive strategies. While Bogle dramatically changed the way millions of people invest, he did not invent value investing. His approach is distinct from that of Benjamin Graham, who promoted investing in individual companies that were undervalued relative to their intrinsic worth. Bogle’s focus was on accessibility, efficiency, and minimizing costs, whereas value investing requires detailed company analysis and active stock selection. Both Bogle and Graham promoted disciplined, long-term thinking, but their methods and goals differ. John Bogle made investing simpler and cheaper for the masses, but he is not the originator of the value investing philosophy.
