Mr. Market - Explained
A beginner-friendly explanation of Mr. Market in value investing.
Mr. Market Explained
A mental model introduced by Benjamin Graham representing the stock market as a manic-depressive investor who offers prices that fluctuate wildly based on emotions rather than fundamentals.
What It Means for Investors
The Metaphor
Imagine you own a minority stake in a private business. Every day, your partner (Mr. Market) appears with an offer to buy your share or sell you his at a price he conjures from thin air.
Some days he's euphoric and offers astronomical prices. Other days he's depressed and offers tiny fractions of what the business is truly worth.
The key insight: Mr. Market is there to serve you, not to guide you. You are sane; he is insane.
Why This Matters
"Be fearful when others are greedy, and greedy when others are fearful." ā warren-buffett
Most investors treat Mr. Market's prices as truth. They:
- Sell when prices crash (fear)
- Buy when prices soar (greed)
- Check prices daily as if checking a scorecard
Intelligent investors do the opposite: They use Mr. Market's irrational prices to their advantage.
