Learning 1 · Introduction

Many 'Most Important' Things

The idea

Marks wrote that he kept saying 'the most important thing is...' about different ideas, so the book is built of many.

Background

It grew from his memos to clients of Oaktree Capital.

Takeaway

Investing success comes from many things done well.

Second-Level Thinking

The idea

First-level thinking says 'good company, buy'. Second-level asks what's already priced in and what others expect.

Example

A great company may be a bad investment if everyone already loves it.

Takeaway

Think deeper than the crowd.

Market Efficiency and Its Limits

The idea

Markets are often efficient, but not always. Mispricings come from emotion.

Example

Neglected or feared assets can be cheap.

Takeaway

Look where others aren't.

Controlling Risk

Cycles

The idea

Markets and economies move in cycles. Things never go in one direction forever.

Expect cycles.

The Pendulum

Go against the crowd wisely.

The Role of Luck

The idea

Short-term results are heavily influenced by luck.

Judge decisions, not outcomes.

Investing Defensively

The idea

Avoiding losers matters more than finding winners.

Example

Marks quotes the idea that there are old investors and bold investors, but few old bold investors.
