After analyzing ~200 quality companies, I put together a small wiki that breaks down the different types of competitive advantages (moats).

What’s inside: - 48 distinct competitive advantages - Grouped into 5 categories

For each advantage: - Plain-English explanation - Pros and cons - Why it exists and how it shows up in real businesses - Signals that suggest durability vs. decay - Common patterns and notes from real companies

Built mainly as a thinking framework for investors, not a stock-picking list.
