Economic Moat

In the brutal warfare of capitalism, success attracts competition. If a company makes high profits, rivals will come to steal them—unless the company has a defense. Warren Buffett calls this the "Economic Moat," and it is the single most important concept for long-term investors.



This book is a deep dive into the art of identifying durable competitive advantages that protect a business from attack. It moves beyond simple financial ratios to analyze the qualitative structural features that create a true moat: network effects, switching costs, intangible assets (like brands or patents), and cost advantages.



"The Economic Moat" teaches investors how to distinguish between a fleeting trend and a fortress, explaining why some tech companies are fragile despite high growth, while boring industrial firms might be unassailable. Whether you are a value investor or just trying to pick stocks that won't go to zero, this book provides the mental models to assess the longevity of a business's profits.
