In one sentence: Phil starts Munger's fourth principle, "a price that makes sense", by treating a company like a rental house: buy owner earnings at a yield you'd want, project them forward, and use Whole Foods to show the arithmetic and the check on buybacks.
Key ideas
- The 10-10 rule. Don't buy for ten minutes unless you'd hold ten years with no quotes. Phil says to imagine someone shouting your home's price daily; the aim is to stop caring. [01:00–05:00]
- The punch card. Imagine 20 punches for your whole investing life (the same idea as the "twenty punches" in earlier notes). It makes you wait for high certainty. [04:00–06:00]
- Rule of 72 and real return. The La Jolla/Del Mar example: a house sold for $205k in 1985 and now worth about $1.2M doubled about every 12 years, so 72 ÷ 12 ≈ 6% a year. With inflation near 3% long-run (higher in 1975–85), the real gain is about 3%. [06:00–14:00]
- Munger's fourth principle is "a price that makes sense" (Munger, BBC 2012). That means making sense as a business, not a speculation. You can't judge it unless you understand the business, have a moat to predict the future and trust management. [15:00–18:00]
- Price like real estate. Rent less insurance, taxes and maintenance gives owner earnings. Phil's toy example: $9,000 a year. At a 10% yield you pay $90,000 (earnings × 10). [18:00–23:00]
- Project forward. If earnings grow 6% a year they nearly double in ten years (about $17,000), and at the same 10x multiple the property would be worth about $170,000. The moat for real estate is location. [20:00–25:00]
- Same for a company. Whole Foods: about $900M owner earnings (his rough figure). At 10% yield, value ≈ $9B, versus a market cap of about $9.78B (318.4M shares × $30.70). Market cap is price × shares. [25:00–29:00]
- Why it was cheap. Whole Foods fell from about $60 to the high $20s on competition worries, after $90 when it was growing about 20%, and to about $5 in 2008–09 with no debt. Phil asks whether the problem is a broken moat or an event fixable in about three years. [30:00–34:00]
- Payout check. Last year it paid about $1.1B in dividends plus buybacks ($944M repurchases plus $177M dividends), around 11–12% of the price. Find it in the cash flow statement under repurchase of stock and dividends paid. [33:00–38:00]
- Buybacks only help below value. Phil guesses fair value near $60, so buying at $30 is good; buying at $70 or $80 would be foolish. [38:00–40:00]
- Three statements, a memory trick. Danielle: income statement = money coming in, balance sheet = money sitting there balanced, cash flow = money flowing out. [35:00–37:00]
- Next time: screen for companies on sale and ask why. [40:00]
How it maps to RuleOne
- The yield-versus-price framing is what the screen's owner-earnings or free-cash-flow yield column shows. A 10% yield is Phil's illustration, not a rule.
- Market cap and the payout (dividends plus buybacks) are on /stock/TICKER/; compare buybacks with your own value estimate.
- The "event" question (broken moat or fixable) is the filter for any big drawdown in the event feed.
- Treat Whole Foods numbers as 2016 illustrations. They are Phil's ballpark figures, not data from the site.
Buffett, Munger and Graham links
- Margin of safety is Graham's idea (The Intelligent Investor, chapter 20; the title words "three most important words" are from there). 001 has Munger's list.
- Owner earnings is Buffett's 1986 letter concept.
- Buybacks only when price is below value: Buffett's 1984 and 1999 letters.
Words to know
- Owner earnings: cash a business produces for its owners after expenses.
- Yield (earnings yield): owner earnings ÷ price.
- Market capitalisation: shares × share price.
- Rule of 72: years to double = 72 ÷ growth rate.
Try this
On /stocks/ pick a company, take its free cash flow, and divide by market cap to get the yield. Project it forward ten years at a conservative growth rate and multiply by ten. Compare with today's price.
Check yourself
- If a rental produces $9,000 of owner earnings, what price gives a 10% yield?
Answer
$90,000 ($9,000 ÷ 0.10). - Roughly how fast does something grow if it doubles every 12 years?
Answer
About 6% a year (72 ÷ 12). - When is a buyback good for shareholders?
Answer
When the price is well below intrinsic value; at a high price it destroys value. - Where do you find buybacks and dividends in a 10-K?
Answer
In the cash flow statement, as repurchase of stock and payment of cash dividends.
