How do you invest in a company like ASML when even its engineers cannot fully explain the machine? This episode tackles the investing paradox at the heart of one of the world’s most complex businesses—and why that complexity may be part of its moat.
We discuss why ASML’s EUV machines, with more than 200,000 parts, are so hard to replicate; why switching suppliers is nothing like replacing a printer; and how that shapes the company’s competitive advantage. The conversation also connects Charlie Munger’s circle of competence to real-world investing decisions, exploring why honest uncertainty can be a better edge than false confidence.
You’ll learn:
- Why ASML’s complexity can be a barrier to competition
- How to think about the circle of competence
- Why the “too hard pile” can still contain promising investments
- What a deep dive into LAM Research revealed about semiconductors, etching, deposition, and cleaning
- How to focus on the one or two facts that matter most
This episode is a reminder that understanding every detail is often impossible, and usually unnecessary. What matters is assessing whether a business has a durable edge, whether customers can realistically switch, and whether that advantage could last.
If you invest in semiconductors, AI infrastructure, or businesses that feel too complex to analyze, this episode offers a framework for thinking through the challenge.
