The lessons

  1. 12.1

    Losing hurts twice as much as winning feels good

    The asymmetry behind many bad selling decisions.

  2. 12.2

    What checking daily does to your decision-making

    More information, worse decisions. The mechanism is well documented.

  3. 12.3

    Recency bias โ€” why last month feels like forever

    The most recent thing feels like the most likely thing.

  4. 12.4

    The gap between fund returns and investor returns

    The fund returned one number. The people in it returned another.

  5. 12.5

    Confirmation bias and the research you didn't do

    Looking for reasons you were right is not research.

  6. 12.6

    Anchoring on your buy price

    The market does not know what you paid, and does not care.

  7. 12.7

    FOMO and why the story arrives before the numbers

    By the time it's a narrative, the price has often moved already.

  8. 12.8

    Overconfidence and how often you trade

    The more certain you feel, the more it tends to cost.

  9. 12.9

    Writing down why you bought something

    The cheapest tool in investing, and the least used.

  10. 12.10
