What is a moat?
← Back to FAQ
A moat refers to a company’s sustainable competitive advantage that protects it from competitors. The term is inspired by the defensive moat around a castle, which prevents outsiders from easily attacking or entering. In investing, a moat describes the strengths that help a company maintain its market position and profitability over time.
A strong moat helps a company defend its long term earnings power.
A moat can come from various sources such as strong brand recognition, cost advantages, patents, network effects, or high switching costs for customers. Companies with wide moats are often able to maintain higher profit margins and resist competitive pressure.
Investors value moats because they increase the likelihood that a company can generate stable cash flows for many years. However, moats are not permanent. Technological change, new competitors, or shifts in consumer behavior can weaken even strong competitive advantages.
Short example:
Suppose a global beverage company has a powerful brand that customers recognize worldwide.
Retailers want to stock its products because consumers specifically ask for them, giving the company strong pricing power.
Even if a new competitor offers a similar drink at a lower price, many customers remain loyal to the established brand. This brand strength acts as a moat, helping the company protect its market share and maintain consistent profits over time.
