Investment Philosophy
The Berkshire Hathaway investment philosophy is a synthesis of rigorous financial analysis, a specific psychological temperament, and the application of multiple Mental Models.
Origin
The philosophy began as a pure Value Investing approach under Benjamin Graham but evolved into a broader "Business Owner" perspective.
Chronological Evolution
- Early Era: [Deep Value] -> Focused on price-to-asset discrepancies (the "Cigar Butt").
- 1980s: [Institutional Imperative] -> Formalized the need to resist the tendency of corporate managers to imitate their peers.
- 2004: [Uncommon Sense] -> In the 2004 Meeting, Buffett and Munger defined their success as "uncommon sense"—the ability to tune out folly.
- 2004: [Grouping & Exclusion] -> Buffett used the chess computer analogy (Fischer vs. Spassky) to explain how they eliminate 99.99% of possibilities instantly: "Getting rid of the nonsense... we can hang up very fast."
- 2004: [The Danger of Leverage] -> Re-emphasized that leverage is the only way a smart person can go broke: "If somebody else can pull the plug on you during the worst moment... you go broke."

"Part of it, I think, is being able to tune out folly as distinguished from recognizing wisdom. And if you just got whole categories of things you just bat away... then you’re better able to pick up a few sensible things to do." — Charlie Munger, 2004 Meeting
"A Fischer or Spassky, essentially, was eliminating about 99.99% of the possibilities without even thinking about it... get right down to the few possibilities that really had any chance of success." — Warren Buffett, 2004 Meeting

🌱 Idea Evolution & Maturity
How this concept developed over time, tracking its transformation from an early practice to a formalized Berkshire pillar.
Graham's Cigar Butts
Buffett adopts a strict quantitative approach, buying cheap assets regardless of business quality.
Investing is about mathematical safety and liquidating value.
We looked for cigar butts with one free puff left.
The Fisher/Munger Shift
The philosophy shifts to buying high-quality businesses with durable competitive advantages (moats).
It's better to buy a wonderful company at a fair price than a fair company at a wonderful price.
Time is the friend of the wonderful business, the enemy of the mediocre.
The Four Tenets
The philosophy is crystallized into four rules: Understand the business, durable competitive advantage, honest/able management, and sensible price.
Investing is business analysis. You are buying a piece of a business, not a ticking stock symbol.
We look for businesses we understand, with a durable competitive advantage, run by able and honest people, available at a sensible price.
The Immutable Law
The philosophy is fully mature and proven across decades and macroeconomic environments.
The principles of intelligent investing are permanent and unchanging.
The basic principles of intelligent investing do not change.
