(John Wiley & Sons) In this tenth anniversary edition, Bogle updates his look at mutual funds and the business of investing. He examines the fundamentals of mutual fund investing in turbulent market environments and offers advice for building an investment portfolio. Arguing that a low-cost, broadly diversified portfolio continues to be the best way to build wealth at the lowest cost and risk, Bogle also emphasizes long-term investing and asset allocation. The book’s updated charts, commentary, and analysis reflect recent changes in investment vehicles and market performance. The creator of the first index mutual fund, Bogle is the founder of the Vanguard Mutual Fund Group and president of its Bogle Financial Markets Research Center. He is the author of Enough: True Measures of Money, Business, and Life and The Little Book of Common Sense Investing: The Only Way to Guarantee Your Fair Share of Stock Market Returns .
