Charlie Munger’s Checklist
Incorporating all the principles we’ve learned so far, here is the 10-step Charlie Munger checklist for making investment decisions.
1. Think Independently
- Don’t follow the folly of crowds. Make up your own independent mind, ignoring who agrees or disagrees with you.
- Following the herd guarantees you’ll regress to the mean and have average results.
2. Stay Humble
- Recognize your circle of competence and stay within it.
- Find evidence that disagrees with your most sacred beliefs.
- Recognize when you’re overconfident and deluding yourself about your certainty.
3. Prepare and Work Hard
- Learn constantly through continuous reading. Try to get a little smarter every day.
- Build a broad base of knowledge across many different fields of study. Build a wide latticework of mental models.
- Keep asking “why?” to understand how things work.
4. Analyze Rigorously
- Understand the value of businesses independent of price; real growth independent of motion; and wealth independent of size.
- Use checklists to avoid biases and omissions.
- Don’t lose the forest for the trees—understand the few major effects that really matter instead of the many minutiae that don’t.
- Look at second- and third-order effects.
- “Invert, always invert.”
5. Measure Risk
- Avoid working with people without integrity.
- Avoid big mistakes that can wipe you out.
- Seek compensation commensurate with risk taken.
- Build in a margin of safety.
- Safeguard your reputation—trust can be lost in a single decision.
6. Allocate Assets Wisely
- Remember that the real cost of an investment is the opportunity cost.
7. Be Patient
- If you don’t see good opportunities, be content to sit on your hands and do nothing. The tendency to act can lead to bad decisions and unnecessary costs.
- Allow compound growth to work its magic—being a little better over long periods of time can lead to amazing things.
8. Be Decisive
- “Be fearful when others are greedy, and greedy when others are fearful.”
- When the odds are in your favor, bet big.
9. Adapt and Change
- The world won’t adjust to you; you need to adjust to the world.
- Be willing to kill your most beloved ideas.
- Recognize when you’re wrong and learn from it. Denial hurts.
10. Stay Focused
- Don’t get overconfident. Don’t get bored.
- Make sure your investments and businesses perform optimally.
- If you have problems, face them head-on instead of ducking from them.
