Investing Psychology Chapter 9: The Final Roundup
We’ve reached the end of the tour. In the final chapter of “Investing Psychology,” Tim Richards pulls back the curtain on the entire investment industry.
He compares the industry to a top-class magician. They use “joint attention” to keep your eyes on one thing while they perform the trick somewhere else. The industry is a “gigantic machine designed to separate us from our money while keeping us in a state of vague happiness.”
The Embezzlement Machine
The really cruel part is that it’s all perfectly legal. The industry uses your own brain’s glitches—your overconfidence, your herding instinct, your fear of missing out—to make you a willing participant in your own financial loss.
Even finance professors don’t follow their own advice. They know the theories, but they still trade like emotional humans. Knowing the bias isn’t enough; you have to build systems to stop it.
The Texan Sharpshooter
Most investment “gurus” are like a guy who shoots a bunch of holes in a barn and then draws a target around the tightest cluster. They find a few successful examples and claim they have a “system.”
This is the Texan Sharpshooter Effect. Anecdotes are not evidence. One guy getting rich off a meme stock doesn’t mean you will too. Look at the stats, not the stories.
The 7 Rules for Survival
If you take nothing else away from this series, remember these 7 rules. Print them out. Stick them on your monitor. Read them before you hit “buy” or “sell.”
- You ARE biased. Don’t pretend you’re the exception. recalibrate your decisions assuming you’re wrong.
- Don’t trade hungry or emotional. If you’re stressed, tired, or just had a fight, stay away from your brokerage account.
- Don’t compete with institutions. You can’t win a speed race. Your only edge is being a long-term holder.
- Demand evidence. Don’t trust “talking heads” or Twitter gurus without a verifiable track record.
- Prove yourself wrong. Actively hunt for reasons to SELL your favorite stock. If you can’t find any, you aren’t looking.
- Generate feedback. Use a diary. Compare your expectations to reality every 6 months.
- Track your results. Don’t let your brain “delete” your losses.
Conclusion
This isn’t the end of the journey; it’s the beginning. Behavioral finance isn’t just about money; it’s about understanding the “enemy within”—your own brain.
If you can stop being your own worst financial enemy, you’ve already won half the battle. Good luck out there.
