In one sentence: Phil and Danielle discuss why even a skilled investor like Ackman can break his own checklist, argue for humility and simple businesses ("six-inch bars"), and show the same list can warn you to hedge or exit when a company's story changes.
Key ideas
- Learning curve. Phil compares investing to snowboarding: the basics are simple and a good instructor speeds you up, but shortcuts fail when the hill gets steeper. Danielle defends her practice shares as part of learning. [00:00–07:00]
- Boards of directors. Danielle ran a case study on Adobe's board. Her takeaway: a couple of hours is enough to learn whether a board is normal or an outlier, and only outliers deserve more time. [07:00–12:00]
- Phil's view of boards. He has a low opinion of them: they are not real fiduciaries and avoid upsetting anyone. He wants skin in the game for boards and top managers, and notes Adobe requires directors to own stock and pays them largely in stock. [12:00–18:00]
- Activist investors. A new activist on a board is worth studying; the question is whether they push for the long term, as Ackman did at Chipotle. [13:30–16:00]
- Why a checklist can still fail. Danielle suspects Ackman did "follow" his list, but in a business he did not actually understand, so it only seemed simple. Phil compares it to scouting a river rapid from above: it looks like ones you have run, and then you find you didn't know what you didn't know. [18:00–22:30]
- Keep it simple. Buffett says this game is not won by the highest IQ; jump over "six-inch bars, not six-foot bars". There are few six-inch bars, and they show up when institutions are forced sellers. [22:30–25:00]
- Individual advantages. No one forces you to swing at every pitch; you can sit in cash or government bonds for two years. And you know what you don't know. [25:00–27:00]
- Confidence versus arrogance. Danielle's point: checklists are aimed at your weakness. Overconfident people need to dial back, while hesitant people need a list that builds confidence. Both are helped by Munger's "stay pessimistic". [27:00–30:30]
- Reading the list. Danielle notes that "that we can't control" in "extrinsic risk" matters, and "doesn't need outside capital" forces a check on how long the company can fund itself. She files free cash flow under management rather than moat, and Phil agrees that works. [30:00–33:30]
- Carnival example. Walking the list, a cruise line looked strong until you asked what extrinsic risk could crush it: a pandemic. News of the virus in China came in December, with a couple of months before markets fell, so a holder had time to hedge or exit as the story changed. Phil did not own it because it was not on sale. [33:30–36:00]
- Use the list as a change detector. If any of the eight points shifts, dig further, then hedge or sell. Margin of safety and events are not on Ackman's list; Phil adds them. [35:00–37:30]
How it maps to RuleOne
- The holdings page is where to record the original story so that a change against it can be spotted. See 284 for an IBM example of exiting when the story changed.
- The screen cannot judge boards. A short, time-boxed board look (bios, ownership, pay) is something to do by hand.
Buffett, Munger and Graham links
- Buffett's "six-inch bars" idea is from his 1990s talks and letters; Phil cites it from memory, so check the source before quoting it.
- Munger's habit of inversion and "stay pessimistic" (Poor Charlie's Almanack, speeches) is behind the humility theme.
Words to know
- Activist investor: an investor who takes a stake and pushes the board and management to change course.
- Fiduciary: someone legally required to act in another's interest.
- Story change: a shift in business, management or moat that invalidates why you bought.
Try this
Take a company you own or watch and write the eight Ackman points as a checkbox list in your notes. Beside each, add "what would make this false?" Revisit it once a quarter at /holdings/.
Check yourself
- Why might a checklist user still fail?
Answer
They can believe a business is simple when it isn't, because they don't know what they don't know. - Which extrinsic risk did the Carnival example expose?
Answer
A pandemic, which could halt cruises. - What should a short board review aim to find out?
Answer
Whether the board is normal or an outlier, so you only spend more time on outliers.
