Peter Lynch believes that average investors have advantages over Wall Street experts. Since the best opportunities can be found at the local mall or in their own places of employment, beginners have the chance to learn about potentially successful companies long before before professional analysts discover them. This headstart on the experts is what produces "tenbaggers", the stocks that appreciate tenfold or more and turn an average stock portfolio into a star performer. In this fully updated edition of his classic bestseller, Lynch explains how to research stocks and offers easy-to-follow directions for sorting out the long shots from the no shots. He also provides valuable advice on how to learn as much as possible from a company’s story, and why every investor must ignore the ups and downs of the stock market and focus only on the fundamentals of the company in which they are investing.
