The Parable of Mr. Market (The Intelligent Investor, Ch. 8) · 1949
Benjamin Graham's Mr. Market allegory, explained
The single most useful mental model for surviving volatile markets — imagine your business partner is a moody manic-depressive.
In Chapter 8 of The Intelligent Investor, Benjamin Graham introduces a character who has shaped how great investors think about price: Mr. Market.
The parable
Imagine you own a stake in a private business, and your partner — Mr. Market — shows up every day quoting a price at which he'll buy your share or sell you his. The catch: he is emotionally unstable. Some days he is euphoric and names a wild, high price; other days he is despondent and offers to sell for almost nothing. Crucially, he doesn't mind if you ignore him — he'll be back tomorrow with a new quote.
“The market is there to serve you, not to instruct you.”
Why it's liberating
The lesson is that market prices are opportunities, not verdicts. You are free to transact only when Mr. Market's mood is convenient — buying when he's fearful, selling when he's greedy — and to do nothing the rest of the time. Warren Buffett has called it the best idea ever written about investing. It converts volatility from a threat into a source of bargains.
- Price is what a moody counterparty offers; value is what the business is worth.
- Volatility is the value investor's friend, not their enemy.
- You never have to act on any given quote.
