Summary

Circle of competence” sounds fancy, but it’s really just this: know what you know, and know what you don’t. In this episode, Stephen and Andrew break down how most investing mistakes happen when you get confident in a business you don’t truly understand—even if the company feels familiar on the surface. You’ll learn how to define your circle of competence, how to expand it safely over time, and how to avoid common traps like investing in “cool” companies or getting swept up in market narratives. Stephen also shares a simple pen-and-paper method to quickly test whether a company is truly inside your circle.
