In one sentence: A rerun of 332: Danielle reads Buffett's 1979 to 1983 letters on inflation and lands on three tests (earn more from price rises without new capital, carry little debt, measure in purchasing power); nothing substantive is new beyond a short spoken intro.
Key ideas
- Rerun. The body is the same talk as 332, which has the full notes. The new part is a short intro saying the hosts couldn't record this week, and a nudge to watch the Netflix annual-meeting webcast. [00:00–01:30]
- Buffett only wrote about inflation once it was severe. Danielle's reading: he skipped it in the 1977 and 1978 letters and wrote most of the 1979 letter on it, which began his move to larger financial themes. [02:46–05:00]
- The tapeworm. In the 1981 letter inflation "acts as a giant corporate tapeworm," eating dollars for receivables, inventory and fixed assets just to keep the same unit volume. [06:30–08:00]
- Test 1: raise prices without new capital. Look for a business whose earnings rise with its prices without adding capital, and which can handle more dollar volume cheaply. A superstar manager on top is better still. [09:00–15:00]
- Test 2: little debt. Danielle says this is her inference from other letters. She quotes the 2010 letter, "credit is like oxygen," on why borrowers can be sunk when refinancing dries up. [15:30–19:00]
- Test 3: measure purchasing power, not earnings. Inflation is a hurdle: with 12% inflation, a business earning 20% on equity and paying it out is shrinking its capital in real terms ("running up a down escalator"). [19:00–21:30]
- Be ready to change premises. Danielle quotes Buffett on how old yardsticks cost you when change is fast. Such companies are good in any environment, so they are "anti-fragile." [22:00–23:30]
- The Noah principle. Predicting rain doesn't count; building arks does. [24:00]
How it maps to RuleOne
- The screen's ROIC and Big Five numbers test the first two points: high returns on capital, low debt, growth that doesn't swallow cash. See 332.
- Free cash flow and owner earnings are the practical form of "converts earnings into cash."
Buffett, Munger and Graham links
- Buffett's 1979, 1980 and 1981 letters on inflation; the 1983 letter's appendix on economic goodwill; the 2010 letter on debt.
- Related earlier Danielle episodes on the same letters: 004, 090.
Words to know
- Purchasing power: what a given amount of money can actually buy.
- Hurdle rate: the return you need just to keep up (here, with inflation).
Try this
Take one company on /stocks/ and compare its five-year capital spending with its operating cash flow. If most of its cash goes back into just keeping the business the same size, it fails Buffett's first test.
