Fear and Greed Contrarianism

R — Original Text (Reading)

"We simply attempt to be fearful when others are greedy and to be greedy only when others are fearful."

— Warren Buffett, 1986 letter

It is not simply "reverse operation," but a contrarian framework based on intrinsic value:

"Be fearful when others are greedy": when market prices are high, confidence is exuberant, and stories sound compelling → prices may already exceed value → do not buy/consider selling
"Be greedy when others are fearful": when the market is panicking, confidence is collapsing, and "this time it's over" → prices may be far below value → consider buying
Key premise: You must be able to independently assess intrinsic value—otherwise you do not know whether the price during "greed" is expensive or cheap
This is the concrete action version of the Mr. Market framework

Problem: The market is in extreme panic; should one hide in cash?
Use: Be greedy when others are fearful—inject $800 million and $300 million into Goldman Sachs and GE
Result: Obtained favorable terms and substantial returns

Problem: All tech stocks soared, and value investors lagged severely
Use: Be fearful when others are greedy—persist in not investing in tech stocks you do not understand
Result: Avoided the bubble burst, while chasers suffered heavy losses

The market has risen for months, and everyone around you is making money
An asset has fallen sharply from its high, and the news is full of panic
Someone uses "this time is different" to persuade you
FOMO (fear of missing out) is strong
You want to "cut losses" to stop the bleeding, but the fundamentals have not changed

Difference from mr-market : Mr. Market is a cognitive framework (how you view prices), while fear and greed is an action principle (when you buy/sell)
Difference from real-conservatism : Conservatism ≠ tradition is about not following blindly, while fear and greed is about contrarian action

Diagnose market sentiment
- Completion standard: Determine whether the current state is "extreme greed/greed/neutral/fear/extreme fear"
- Reference signals: sentiment of news headlines, frequency of discussion around you, valuation levels
Return to intrinsic value(not contrarian trend-following)
- Completion standard: Independently assess intrinsic value, and mark the gap between the current price and value
- Stop condition: If you cannot assess intrinsic value → do not act (contrarian ≠ gambling)
Execute contrarian operation
- Extreme greed + price > value → reduce position/do not buy
- Extreme fear + price < value → add to position/buy
- Sentiment is extreme but value is uncertain → take no action

It is not "always do the opposite"—sometimes the majority is right (such as the sustained rise after March 2009)
It requires extremely strong psychological fortitude and independent capital—people forced to sell at the lowest point are not irrational, but have no choice
"Others are fearful" does not mean "the bottom has arrived"—fear can last a long time
Author's blind spot: Buffett has permanent capital (insurance float), so he can keep buying while others are fearful—retail investors do not have this condition
