In one sentence: The big four growth rates (book value, earnings, sales and operating cash per share) should rise together at about 10% or more a year, because that pattern hints at a moat, while a tangle of unrelated lines, as at General Motors, is a warning, and operating cash flow is the number that catches accounting fictions first.
Key ideas
- Why four numbers. The four growth rates are hard to manipulate all at once without outright lying. Management can only "colour inside the lines" with clever accounting. If you can't work out what they're doing, move on. [00:00–04:00]
- Values and management, a detour. The spa Rancho La Puerta is offered as an example of founders' values and loyal staff lasting decades. Danielle suggests how a company treats people may matter even more than its product. The meaning of "InvestED": invested in money, committed, personally invested, and "ED" for education. [04:00–18:00]
- EPS is a "fiction". Earnings per share comes from accrual accounting under GAAP, which records sales when made and costs when incurred, whether or not cash moved. It is a useful picture but not what sits in the bank. Receivables and payables show the gap. A profitable firm can run out of cash. [19:00–24:00]
- Sales per share is the top line. Earnings can be pushed up by cutting costs while sales stagnate. IBM at the time of recording had falling revenue but rising earnings, which Phil calls a red flag. [24:00–26:00]
- The pattern to look for. All four growth rates moving the same way at similar speeds over a long period. One far above the others is also a flag. A chart view of the four lines shows this quickly. [25:00–27:30]
- The 10% hurdle. Phil wants an average of at least 10% a year across all four, and says that level held for long suggests some moat, since in a few years rivals notice and compete. [28:00–30:00]
- Chaotic lines mean "too hard". General Motors' lines were all over the map in his book research. Looking out the back window at a bumpy road, you wouldn't expect a freeway ahead. [27:00–28:30]
- A cautionary story. An 82-year-old widow held GM because her husband told her to. Phil says GM borrowed to keep paying the dividend, which hid the trouble. The lesson: dividends are not proof of surplus cash, and an owner should check whether the story changed. This is Phil's account from memory. [31:00–34:30]
- Operating cash flow is the canary. Start from net income, add back non-cash costs, adjust for working-capital timing. The result should match cash from operations and is the first third of the cash flow statement. Some companies, such as real estate firms with high depreciation, show low earnings but heavy cash, so industry knowledge matters. [34:00–37:30]
- Rear-view limit. These numbers describe the past. To project the future you need to understand the business and industry. [37:30–38:00]
- Coming next. Three more numbers (about management) that Phil says matter more than the four. CEO judgment is subjective (Buffett praising IBM's CEO while others criticised her), but some numbers don't lie. [38:00–40:30]
How it maps to RuleOne
- The screen and stock pages show book value, EPS, sales and operating cash per share growth. Check them side by side, as in the chart view Phil describes, and look for similar slopes at 10%+.
- A high earnings number alongside weak operating cash flow is the kind of mismatch worth surfacing as a flag in the screen.
- The planned analyst's Understand step should state whether the four lines agree and which statement each number came from.
- Dividend coverage by cash flow (not by borrowing) is something to check on a Holdings position that pays one.
Buffett, Munger and Graham links
- Buffett prefers owner earnings to reported earnings (1986 Berkshire letter appendix), which is the same instinct as favouring cash over accrual profit.
- Graham, The Intelligent Investor (ch. 11–12) and Security Analysis, warns of reported earnings that can be shaped by accounting choices.
- Munger's "too hard pile" applies when the numbers are chaotic (see 002).
Words to know
- Accrual accounting: recording revenue and costs when earned or incurred rather than when cash moves.
- GAAP: Generally Accepted Accounting Principles, the rules public companies follow.
- Accounts receivable / payable: money owed to the company / money it owes.
- Operating cash flow: cash generated by running the business, first section of the cash flow statement.
Try this
On a stock page from /stocks/, compare the 5- and 10-year growth of sales, EPS, book value and operating cash per share. Mark each as at or above 10%, and note whether any line is far from the others. Then write one sentence on whether the pattern suggests a moat or a reason to move on.
Check yourself
- Why is EPS called "fictional"?
Answer
Accrual accounting records sales and costs when they occur, not when cash moves, so profit need not match cash in the bank. - What pattern across the four growth rates is a warning?
Answer
Lines that diverge: for instance earnings rising while sales are flat or falling, or lines that move erratically. - Why watch operating cash flow?
Answer
It reflects cash actually generated and is hardest to dress up, so a gap with earnings shows trouble early. - What does the 10% average across all four suggest?
Answer
Some durable advantage, since competitors would otherwise copy and erode the growth. It is a hint to investigate, not proof.
Short quotes
"The fourth number is where you can see the bad stuff first… the canary in the coal mine." (Phil, ~34:00, auto-transcribed)
