Moat / competitive advantage
A moat is whatever makes it hard for competitors to copy a company's business or take its customers, so it can keep earning good profits for years. The word compares the company to a castle protected by a moat.
Why investors care about moats
A business that earns high profits attracts rivals who want a share of them. Without some protection, those profits get competed away. A moat is the reason a company can defend its profits for longer than usual. The investor Warren Buffett helped popularise the idea.
Common kinds of moat
Brand: customers choose it first and will pay a little more for it.
Switching costs: leaving is expensive or annoying, for example when moving all your data and habits to another provider.
Network effects: the product becomes more useful as more people use it.
Cost advantage: the company can make or deliver at a lower cost than rivals because of its scale or its way of working.
Licences and rules: a permission that few others can obtain.
A moat is not permanent
Moats can narrow. New technology, new rules or careless management can weaken one. Many investors look for evidence over several years, such as steady profit margins and good returns on the money the business uses, rather than trusting a story.
What a moat does not tell you
A strong moat does not make a share a good buy. The price you pay still matters. Maetis teaches you to judge the business first and its price second.
Two shops
Two shops sell the same goods. One has a loyal local following. The other competes only on price. A cheaper rival opens nearby: the second shop loses customers quickly, while the first loses few. That loyalty is the first shop's moat.
Common questions
- What is the meaning of moat in stocks?
- It is a lasting advantage that protects a company's profits from competitors, such as a strong brand, high switching costs or a cost advantage.
- Can a company lose its moat?
- Yes. Technology, regulation, competitors and management mistakes can all narrow a moat over time.
- How can I spot a moat?
- Look for the reason customers stay, such as loyalty or the cost of switching, and check whether margins and returns held steady through hard years. This is a way of thinking, not a guarantee.
- Does a moat mean I should buy the share?
- No. A good business can still be a poor investment if you pay too much for it.
