In one sentence: Phil and Danielle finish Ray Dalio's five steps to inevitable success, with a focus on step 3, finding the root cause of a mistake. Phil's almond-orchard loss shows that the root cause was not inverting the investment, and they then ask what buying an index really bets on.

Words to know

Try this

Pick one company on your watchlist from All stocks. Write down five ways the investment could lose money, including operator risk, a contractor or supplier failing, and a government risk. Then note which one you could insure against or avoid with a larger margin of safety.

Check yourself

  1. What is the difference between steps 2 and 3 of Dalio's list?
    AnswerStep 2 is noticing the mistake, which is easy. Step 3 is diagnosing the root cause, which is hard and often involves a weakness of your own.
  2. Why wasn't "check the tree shaker's airbags" the real lesson from the orchard?
    AnswerIt fixes one symptom and can't scale across a portfolio. The root cause was never inverting the idea to ask how the business could fail.
  3. Why isn't buying an index a neutral choice?
    AnswerYou are betting on one country's economy and government. Japan's market shows that even a developed country's index can go nowhere for decades.
