Updated with a new chapter that draws on behavioral finance, the field that studies the psychology of investment decisions, here is the best-selling, authoritative, and gimmick-free guide to investing. Burton G. Malkiel evaluates the full range of investment opportunities from stocks, bonds, and money markets to real estate investment trusts and insurance, home ownership, and tangible assets such as gold and collectibles. This edition includes new strategies for rearranging your portfolio for retirement along with the book's classic life-cycle guide to investing, which matches the needs of investors in any age bracket. A Random Walk Down Wall Street long ago established itself as a must-read, the first book to purchase before starting a portfolio, and it remains the best investing guide money can buy.
