Moats and Competitive Advantage
A 'moat' is a durable advantage that protects a company from competition. This lesson covers the main types and how to recognise them.
Why this matters for beginners
Without a moat, today's profits get competed away. With one, a company can keep reinvesting at high returns for years.
Main explanation
Common moat types: switching costs (it's painful to leave), network effects (the product gets better as more people use it), intangible assets (brand, patents, regulatory approval), cost advantages (scale, location, process), and efficient scale (a market only supports a few players).
Moats are not permanent. Technology, regulation, and customer behavior can erode them, Nokia and Kodak were once 'untouchable'.
Look for evidence: stable or rising margins over time, pricing power, low customer churn, returns on invested capital well above the cost of capital.
Ask the inverse: if a well-funded competitor tried to take this customer away, what stops them?
Example using a real company
ASML has a near-monopoly in EUV lithography. MSFT has deep enterprise switching costs. AAPL has brand + ecosystem. LVMH has heritage brands. Different moat types, all durable so far.
- →Switching cost: a company running its payroll on a specific software for 15 years won't switch on a whim.
- →Network effect: a marketplace becomes more useful to buyers as more sellers join, and vice versa.
Common beginner mistakes
- ✕Confusing a great product with a moat, products can be copied.
- ✕Assuming a moat lasts forever.
- ✕Ignoring moats that are eroding slowly.

Try the concept on a real company
Run ASML, MSFT, AAPL, and LVMH in the Analyzer and study the business model and competitive position. Try naming the dominant moat type for each.
