8 Innovation

Investment expert Ken Fisher understands what drives the financial markets, and he uses his knowledge and experience to debunk 50 widely held investment myths. Writing in a crisp, straightforward style, Fisher, collaborating with business writer Lara Hoffmans, presents research data that correct much of the investing public’s conventional – but flawed – wisdom. In the process, he explains what shapes markets at the macro and micro levels, and he applies principles of “behavioral finance” to show why people cling to popular but disproven market lore. The result is advice anyone can use to manage any portfolio. While the 50-myths format may be somewhat gimmicky, it’s fun and getAbstract thinks the book offers valuable information for investors of all experience levels. Realizing your investing weaknesses on its pages is both cheaper and easier than making expensive mistakes in the market.

In this summary, you will learn

  • Why investors frequently fall prey to market misconceptions,
  • How to avoid the 50 most common investing myths and
  • How research debunks those myths.

The Power of Myth
Investors often forget that investing is about probability. Your goal is to be right more than you are wrong. Even the greatest market gurus are right only about 70% of the time. If you can improve your odds, you’ll be ahead in the investing game.
