Written by the founders of the Motley Fool US, "Rule Breakers, Rule Makers" contains two investment approaches. Rule Breakers are companies which take their businesses by storm, breaking all the industry conventions and changing the rules of the game. Recent Rule Breakers include America Online or amazon.com; Rule Makers are companies which offer the opportunity to make huge amounts of money over time. These include Coco-Cola, General Electric, Microsoft and Gap. The Gardner brothers apply these approaches to their own market-crushing portfolios which they manage publically on their Web site. The book includes an opening chapter by Chief European Fool David Berger which explains exactly how to apply the book's approach to British shares, and how to invest in the USA.
