Book excerpt: THE NATIONAL BESTSELLING BOOK THAT EVERY INVESTOR SHOULD OWN Peter Lynch is America's number-one money manager. His mantra: Average investors can become experts in their own field and can pick winning stocks as effectively as Wall Street professionals by doing just a little research. Now, in a new introduction written specifically for this edition of One Up on Wall Street, Lynch gives his take on the incredible rise of Internet stocks, as well as a list of twenty winning companies of high-tech '90s. That many of these winners are low-tech supports his thesis that amateur investors can continue to reap exceptional rewards from mundane, easy-to-understand companies they encounter in their daily lives. Investment opportunities abound for the layperson, Lynch says. By simply observing business developments and taking notice of your immediate world -- from the mall to the workplace -- you can discover potentially successful companies before professional analysts do. This jump on the experts is what produces "tenbaggers," the stocks that appreciate tenfold or more and turn an average stock portfolio into a star performer. The former star manager of Fidelity's multibillion-dollar Magellan Fund, Lynch reveals how he achieved his spectacular record. Writing with John Rothchild, Lynch offers easy-to-follow directions for sorting out the long shots from the no shots by reviewing a company's financial statements and by identifying which numbers really count. He explains how to stalk tenbaggers and lays out the guidelines for investing in cyclical, turnaround, and fast-growing companies. Lynch promises that if you ignore the ups and downs of the market and the endless speculation about interest rates, in the long term (anywhere from five to fifteen years) your portfolio will reward you. This advice has proved to be timeless and has made One Up on Wall Street a number-one bestseller. And now this classic is as valuable in the new millennium as ever.
