10 Investment Lessons

1. Believe in history
“All bubbles break; all investment frenzies pass. The market is gloriously inefficient and wanders far from fair price, but eventually, after breaking your heart and your patience … it will go back to fair value. Your task is to survive until that happens.”

2. ‘Neither a lender nor a borrower be’
“Leverage reduces the investor’s critical asset: patience. It encourages financial aggressiveness, recklessness and greed.”

3. Don’t put all of your treasure in one boat
“The more investments you have and the more different they are, the more likely you are to survive those critical periods when your big bets move against you.”

4. Be patient and focus on the long term
“Wait for the good cards this will be your margin of safety.”

5. Recognize your advantages over the professionals
“The individual is far better positioned to wait patiently for the right pitch while paying no regard to what others are doing.”

6. Try to contain natural optimism
“Optimism is a lousy investment strategy”

7. On rare occasions, try hard to be brave
“If the numbers tell you it’s a real outlier of a mispriced market, grit your teeth and go for it.”

8. Resist the crowd; cherish numbers only
“Ignore especially the short-term news. The ebb and flow of economic and political news is irrelevant. Do your own simple measurements of value or find a reliable source.”

9. In the end it’s quite simple. really
“[GMO] estimates are not about nuances or Ph.D.s. They are about ignoring the crowd, working out simple ratios and being patient.”

10. ‘This above all: To thine own self be true’
“It is utterly imperative that you know your limitations as well as your strengths and weaknesses. You must know your pain and patience thresholds accurately and not play over your head. If you cannot resist temptation, you absolutely must not manage your own money.”

– Mark Minervini, Stock Market Wizards
“After a certain high level of technical skill is achieved, science and art tend to coalesce in aesthetics, plasticity, and form. The greatest scientists are artists as well.”

– Albert Einstein
