Core Investment Philosophy
Simplicity Over Complexity
- “Investing is not complicated. The basic framework is simple.”
- You don’t need a high IQ or complex models - you need courage of convictions
- The willingness to act when others are paralyzed is key
- Examples: Junk bonds in 2002, LTCM crisis opportunities, 1974 stock market bargains
The Punch Card Approach
- Imagine you have a punch card with only 20 punches for all investment decisions in your life
- This constraint would force you to think deeply about each decision
- You’d make better decisions and bigger commitments
- “You don’t have to be right about every company. You have to make a few good decisions in your lifetime.”
Circle of Competence
- Focus on what’s important AND knowable
- Many things are important but not knowable (macro predictions, interest rate forecasts)
- Some things are knowable but not important
- Only act within your circle of competence - know its perimeter
Business Valuation
Intrinsic Value Definition
- Intrinsic value = discounted future cash flows over the life of the business
- Similar to valuing a bond with coupons
- Must understand the business’s competitive environment to estimate future cash flows
- If something is not predictable, forget it
Teaching Business Valuation
- Most business schools teach efficient market theory, not practical valuation
- “What you really want a course on investing to be is how to value a business.”
- Teachers who don’t know how to value businesses teach that “nobody knows anything”
- Recommended programs: Columbia (Bruce Greenwald), Stanford (Jack McDonald), University of Florida, University of Missouri
The Fat Pitch
- Wait for opportunities where you KNOW you’re right
- “We’ve known we were right based on those going in”
- Focus on the dominant variables in a business
- Don’t need precision - just need to be generally right about key factors
Risk Management
Self-Reliance in Risk Assessment
- Don’t “farm out” risk evaluation to others
- Use filters to avoid businesses you don’t understand
- If you can’t decide in 5 minutes, you probably can’t decide in 5 months
- Know the perimeter of your circle of competence
Margin of Safety
- Critical concept from Ben Graham
- Never invest at the edge of your competence
- Leave room for error in your assumptions
Limitations of Statistical Models
- Skepticism toward “sigmas” and Gaussian curves in finance
- Mathematical models don’t capture real business risk
- “Beta” measures past volatility, not true investment risk
- Black-Scholes is a “know-nothing value system” - useful for short-term options, dangerous for longer-term
Opportunity Cost & Capital Allocation
The True Cost of Capital
- Munger: “Cost of capital” as applied to equity is “an inanity”
- The real question: What’s your opportunity cost?
- Compare every investment against your best alternative
Dividends vs. Retained Earnings
- Test: Can you create more than $1 of value for every $1 retained?
- If yes, retain; if no, pay out
- See’s Candy example: pays out nearly all earnings because it can’t productively reinvest
Stock Repurchases
- Only make sense when stock is undervalued
- Many companies repurchase to support stock price, not because shares are cheap
- If stock is overvalued, buying even one share is wrong
Derivatives & Financial Weapons
The Derivative Problem
- “Derivative accounting in America is a sewer” - Munger
- Derivatives are “financial weapons of mass destruction”
- Easy to get into, hard to get out of - “like hell”
- Mark-to-model accounting allows unverified “profits”
Leverage Dangers
- The Northern Pacific Corner example: a brewer committed suicide due to margin call
- People don’t learn from financial history
- Leverage turns temporary price dislocations into permanent losses
Executive Compensation
Problems with Stock Options
- Options function as “lottery tickets” unrelated to individual performance
- Option holders benefit from retained earnings but not dividends - misaligned incentives
- Giving options on the whole company to someone running 1% of it is “crazy”
- Repricing when stock falls eliminates downside risk for executives
Compensation Committee Failures
- Directors who need the $150,000 fee are not independent
- “They’re looking for chihuahuas, not Great Danes and Dobermans”
- No real negotiation occurs - it’s “play money” for the board
Berkshire’s Approach
- Pay for performance tied to what’s under individual control
- Willing to pay tens of millions for genuine value creation
- No stock options except where inherited (General Re)
Market Dynamics
Market Dislocations
- Opportunities are brief but extreme
- Example: Tax-exempt money market funds repriced from 3.15% to 10% in weeks
- Same security selling at 11.3% and 6% simultaneously
- “Like spearing a fish that comes by once every ten years”
When to Sell
- Best approach: Buy stocks you never want to sell
- Sell if you need money for something better
- Sell if valuations between markets are out of whack
- “The real thing to do with a great business is just hang on for dear life”
Predicting Markets
- Don’t try to predict currents - focus on how things will swim in whatever currents come
- At any point in history, you can find equally impressive lists of positive and negative factors
- “It won’t be the American economy that does in investors - it will be investors themselves”
Feedback Mechanisms & Self-Deception
Darwin’s Method
- Write down contrary evidence immediately - the mind pushes it away
- Don’t interpret new information to fit prior conclusions
- “A smart man playing his own game can fool you”
Value of a Partner
- A partner who won’t accept things just because you say them
- Charlie Munger as the ultimate feedback mechanism
- Most corporate organizations reinforce CEO biases rather than challenge them
Annual Reports as Feedback
- Reporting on yourself honestly is very useful
- Creates accountability and historical record
Investment Management Industry
Finding Good Managers
- Extremely difficult - Buffett could only recommend two people when closing his partnership
- Must know how they accomplished results, not just the results themselves
- Promotional types are unlikely to meet long-term tests of ability and integrity
The Mutual Fund Scandal
- Managers accepted “bribes to betray their own shareholders”
- “Like a man saying: I’ll kill your mother and we’ll split the insurance money”
- Industry knew but said nothing until a whistleblower acted
Business Education Critique
Efficient Market Theory
- Taught because professors don’t know how to value businesses
- Creates a “priesthood” with Greek symbols and complex math
- “If I taught physics without knowing it, I’d come up with a theory that nobody knows anything”
The Cost of Bad Education
- CEOs don’t know how to value businesses they’re acquiring
- They hire investment bankers who have incentives to recommend deals
- More than 99% of corporate compensation systems are “crazy”
Specific Company Examples
Coca-Cola
- Went public in 1919 at $40/share, dropped 50% first year
- With dividends reinvested, worth well over $5 million now
- Key insight: They would sell a billion servings a day globally
- Depression, WWII, atomic bombs - none of it mattered to the thesis
See’s Candy
- Wonderful business but can’t expand profitably
- Pays out nearly all earnings to Berkshire
- Example of a business that should distribute capital, not retain it
GEICO
- “Absolutely wonderful business” with world’s best manager
- Made mistakes by expanding into mediocre insurance operations
- Illustrates temptation to “prove manhood” by doing difficult things
Department Stores
- Lost all their monopolistic advantages: downtown location, revolving credit, one-stop shopping
- Technology changes can destroy businesses unpredictably
- Internet will have huge impact on retailing
Key Quotes
“You don’t have to have perfect wisdom to get very rich. All you’ve got to do is have slightly more than other people on average over a long time.”
“The idea that very smart people with investment skills should have hugely diversified portfolios is madness.”
“We’re not predicting the currents that will come, just how some things will swim in the currents whatever they are.”
“If you can’t think fast and act resolutely, it does you no good.”
“Big opportunities in life have to be seized. We don’t do very many things, but when we get the chance to do something that’s right and big, we’ve got to do it.”
Practical Advice for Investors
- Focus on valuation - Learn to value businesses, not just stocks
- Stay within your circle - Know what you understand and what you don’t
- Be patient - Wait for fat pitches; you won’t get 500 great opportunities
- Think independently - Don’t let the market’s mood affect your analysis
- Avoid leverage - It turns temporary dislocations into permanent losses
- Concentrate - Diversification is for those who don’t know what they’re doing
- Act decisively - When you see value, commit meaningfully
- Learn from mistakes - “Rub your own nose in them”
- Read constantly - Buffett and Munger spend most of their time reading and thinking
- Have the right temperament - IQ alone won’t do it; discipline matters more
