In one sentence: A rerun of 085, Guy Spier's second interview, covering how to learn what you don't know, why managing your own money is an advantage and why moats are harder to see; the original notes are the main record.
What's new in this airing
- Danielle's intro says the break continues and points to Berkshire's annual meeting news. Nothing else is added. [00:00–01:00]
Key ideas (see 085 for detail)
- Test your understanding in public. Guy publishes short white papers (credit card networks, interest rates), asks for corrections and credits contributors. This shows how much others really know. [01:00–07:00]
- The market doesn't always know more than you. Borrowing a thought from Prem Watsa: don't assume others know more, except where information is withheld. [07:00–09:00]
- Own-money advantage. Professionals feel pressure to be seen acting (the institutional imperative). Buffett dropped an investment when his friend left the company, free of fear of being disliked. [08:00–12:00]
- Handling emotion. Position sizing keeps a 50% fall bearable, and strong relationships (his wife, his father) help through good and bad runs. Handle it just "less badly" than average. [12:00–19:00]
- Value investors aren't hermits. Buffett and Munger talked to people and visited companies. [19:00–21:00]
- Moats. Technology is eroding many, and obvious moats are expensively priced. Looking at many businesses over time builds the skill (the truffle-hunting image), and good businesses buy good businesses. He also says honestly that he often feels ignorant and fearful. [21:00–31:00]
How it maps to RuleOne
See 085. The stock page's moat notes work well as the "white paper": write your two-page view and invite critique.
Words to know
- Institutional imperative: the pull on professionals to act and conform, even when waiting is better (Buffett's term).
Try this
Write a half-page note on one company's moat on its /stock/TICKER/ page. List what you know, what you don't, and who could correct you.
Check yourself
- Why does Guy publish unfinished white papers?
Answer
To draw out corrections and learn the boundary of his knowledge, with no advice on buying or selling.
