Economic Moats: Why Durability Matters More Than Growth

How professional investors think about competitive advantage over time.

An economic moat is not size, popularity, or short-term success.

It is the ability to protect returns over time.

Many businesses grow.

Far fewer maintain advantages that make competition difficult, expensive, or irrational.

Economic moats show up in different forms: Switching costs, brand strength, scale advantages, and distribution.

What matters is not whether a company is growing today, but whether its position allows it to endure tomorrow.

The case studies this week are not predictions.

They are examples of how professional investors think about durability.

Understanding this distinction matters more than any forecast.
