Vanguard Group founder John C. Bogle discusses changes in the culture of the mutual fund industry and how speculation has come to dominate investment. The book presents a hard-hitting look from the creator of the first index fund. Over the course of his sixty-year career in the mutual fund industry, the author has witnessed a massive shift in the culture of the financial sector. The prudent, value-adding culture of long-term investment has been crowded out by an aggressive, value-destroying culture of short-term speculation. Mr. Bogle has not been merely an eye-witness to these changes, but one of the financial sector's most active participants. At the end, he offers advice for investors and a warning for speculators.
