The key ideas in The Most Important Thing

Second-level thinking

First-level thinking says a company is good, so buy the shares. Second-level thinking asks what everyone else already believes, whether the price reflects it, and what happens if they're wrong. Marks argues you can only beat the market by thinking differently from it, and being right.

More can happen than will

Marks borrows a line from the economist Elroy Dimson, that risk means more things can happen than will happen. The future is a range of possibilities, and only one of them arrives. A careful investor prepares for the whole range, including the bad end.

The pendulum

Marks pictures investor mood as a pendulum, swinging between greed and fear and rarely resting at the sensible midpoint. When it's out at greed, people feel safest and pay the highest prices. He doesn't try to predict the next swing. He tries to know where the pendulum is now.

Defence first

Marks would rather avoid losers than hunt for winners. Oaktree's rule, he says, is that if you avoid the losers, the winners take care of themselves. Over time, he argues, the investor who dodges disasters tends to beat the one who swings for glory and sometimes blows up.

Lines worth underlining

  1. Second-level

    To beat the market you have to think differently from the crowd, and be right.

  2. Price

    Price decides the return. A so-so asset bought cheap can beat a great one bought too dear.

  3. Risk

    Risk is the chance of losing money, and it's highest when everyone feels safe.

  4. The pendulum

    Markets swing between greed and fear, and rarely rest in the sensible middle.

  5. Bargains

    When everyone loves an investment, it's usually too expensive. Look for bargains in what others avoid.

Hot take · true or myth?

The best investors make their money by forecasting the economy.

Myth. Marks counts himself in what he calls the 'I don't know' school. He argues that very few people can forecast the economy or markets well enough to profit from it.

One thing to try

Take the market's temperature

This week, pick one market you have money in or are tempted by. Write down whether lenders are eager and whether people around you are boasting about easy gains. If both are true, Marks would say the pendulum is out at greed and it's time for more caution.
