This framework distills the principles Warren Buffett applied at his investment partnership, Buffett Partnership Ltd., from 1956 to 1969. During this period, he delivered exceptional returns without a single down year. Each chapter focuses on a core investing principle, illustrated with excerpts from his partnership letters. The book also explains the three strategies he used: Generals—buying undervalued securities, Workouts—profiting from merger arbitrage, and Controls—taking majority ownership to influence a company’s direction.
