Defining Economic Moats

The term 'economic moat,' popularized by Warren Buffett, refers to a company's durable competitive advantages that protect it from competitors. These advantages allow a company to generate consistent profits and maintain its market position over extended periods. A strong economic moat makes it difficult for competitors to erode a company's profitability, ensuring its long-term viability and attractiveness as an investment.
