Limits of Methods (Benjamin Graham)
Price fluctuates more than value due to human emotion
No magic market-beating formula exists
Never assume a bottom; cheap stocks can always get cheaper
Risk Management (Jesse Livermore)
Irrational risk appetite leads to repeated bankruptcies
Betting against market momentum can crush your capital
Diversification is the most important strategy to manage risk
Concentration Danger (Sequoia Fund)
Concentrated holdings generate wealth quickly but decimate it just as fast
Lack of diversification exposes you to catastrophic single-company failures
Beware companies that cut R&D to rely on price gouging
Emotional Investing (Mark Twain)
Passion and logic do not mix in financial decisions
Past failures cause bitterness that blinds you to golden opportunities
Decide exactly how much you are willing to lose before investing
Market Conditions vs Skill (Jerry Tsai)
A rising tide lifts all boats; do not mistake bull markets for genius
Aggressive, lightning-fast trading fails miserably during recessions
New market climates often reward patient, long-term trades
Overconfidence (Warren Buffett)
Endowment effect makes us overvalue assets simply because we own them
A long streak of success breeds blind spots to industry shifts
Even the greatest investors fail to see competitive threats
Unforced Errors (Stanley Druckenmiller)
Novices lose by making avoidable mistakes; focus on not losing points
Envy and FOMO push investors outside their circle of competence
Stamp out unforced errors rather than constantly chasing big wins
Enduring Volatility (Charlie Munger)
Long-term success requires surviving massive short-term losses without panicking
Insulate yourself from temporary drops caused by external economic factors
The worst time to sell investments is in a panic after a drop
Actionable Advice
Act as if you are only permitted 20 trades in your entire career
Exhaustively research every company and never be afraid to walk away
Eliminate fear, anger, envy, and greed from your portfolio decisions
