The Only Guide to a Winning Investment Strategy You'll Ever Need provides you with a road map to growth and investment opportunities that will help you become a successful investor who consistently makes money rather than loses it. In this guide, investment professional Larry E. Swedroe describes the crucial difference between "active" and "passive" mutual funds, and tells you how you can win the investment game through long-term investments in such indexes as the S & P 500 instead of through the active buying and selling of stocks. In clear language, he shows how the newer index mutual funds out-earn, out-perform, and out-compound the older funds, and how to select a balanced "passive" portfolio for the long haul that will repay you many times over.
