In one sentence: Phil (solo) walks through Bill Ackman's eight investing principles, maps each onto Munger's four filters and Rule #1's Meaning, Moat and Management, and notes what the list leaves out (price, events, inversion) that Rule #1 adds.
Key ideas
- Where the list comes from. Ackman said in a video interview that his firm drifted from these principles a few years earlier and was hurt, then returned to them (he put them in a "deal toy" for the whole firm). Phil uses them as a short overview next to his longer checklist. [02:00–04:00]
- The eight principles (as Phil lists them). Simple and predictable; dominant market position; limited exposure to extrinsic risk we can't control; free cash flow generative; large barriers to entry; excellent management and good governance; high return on capital; strong balance sheet that doesn't need outside capital. [04:00–05:00]
- Missing from the list: "capable of understanding". Ackman is a professional, so that is assumed. For amateurs it is where they fall off the wagon, because they don't know how shallow their look is. [05:00–07:00]
- Meaning. Simple and predictable (a business "so simple an idiot could run it"), dominant position (often 20 to 40% of a market, not a majority), and limited extrinsic risk. [07:00–09:30]
- Extrinsic risk example. Phil lost money on the leading US zinc producer, which had a cost-position moat, when a big commodity holder dumped zinc and the price fell from about $1.10 to 60 cents, pushing the company into Chapter 11. Legislation (coal) is another outside risk. [09:30–11:30]
- Moat. Free cash flow of at least 75% of earnings, ideally 100% or more, and large barriers to entry: regulation (toll bridge), switching costs, brand, secrets (patents), and price (CF Industries' low cost and the need to build near the Mississippi). [11:00–16:30]
- Management. Integrity, talent, and good governance (stewardship of all stakeholders). Phil says governance scores matter less than whether the company fits your own values. [16:30–19:00]
- Money use. High return on invested capital, assets and equity, and a balance sheet with debt of no more than a couple of years of free cash flow, so the company never needs outside capital in a downturn. [19:00–20:30]
- Chipotle as the worked example. Phil bought it years before Ackman did; both were drawn by cash flow, return on capital and a clean balance sheet. That is Radar (an investor you respect) feeding the checklist. [20:00–22:00]
- What Rule #1 adds. A margin of safety, an event that puts the business on sale (retail investors can wait in cash longer than a $10 billion fund), and inversion: argue the sell side better than the people shorting it. [21:30–24:00]
How it maps to RuleOne
- The screen's quality filters (free cash flow versus earnings, return on capital, debt) cover items 4, 7 and 8. Items 1 to 3 and 5 to 6 stay human judgments.
- The 13F-based cloning idea (see 001) is how Ackman's buying could reach the Radar.
Buffett, Munger and Graham links
- Munger's four filters (001): understand, durable moat, good management, price with a margin of safety. Ackman's list lines up with the first three.
- "So simple an idiot could run it" is a Buffett remark Phil cites, with the line "because someday an idiot will".
Words to know
- Extrinsic risk: a risk from outside the company that it cannot control or hedge (commodity dumping, legislation, pandemic).
- Barrier to entry: something that makes it very hard for a competitor to copy the business.
- Inversion: list why the investment could fail, then test each reason.
Try this
On a stock page from /stocks/, score the company 0 to 2 on each of Ackman's eight points. Circle the weakest score and write down the "extrinsic risk" that could break the business.
Check yourself
- Which of Munger's four filters is missing from Ackman's list, and why?
Answer
"Capable of understanding". Ackman is a professional, so it is assumed, though amateurs must check it. - What is an extrinsic risk?
Answer
A threat from outside that the company can't control, such as a dumped commodity or new legislation. - What three things does Rule #1 add to the list?
Answer
Margin of safety, a triggering event, and inversion.
