Benjamin Graham
Mr. Market
A quote is a service, not a verdict
The Intelligent Investor, chapter 8
He turns the entire market into one manic-depressive business partner. What that story actually unlocks is smaller and stranger than it looks.
What actually happened?
Chapter eight asks you to imagine a partner in a private business. His name is Mr. Market and he turns up every single day with a price, ready to buy your share or sell you his. His moods are extreme: elated, he names an absurd figure; depressed, he sells everything cheap. The part that matters comes next. He does not mind being ignored, and he is back tomorrow with a new quotation. Which makes him useful in proportion to how unstable he is, provided you use his prices rather than catch his mood.
A quote is an option, not a grade
Most people read the tape as a live score on their own judgement, so a fall means they were wrong. The parable separates the two. A price is one man's mood today, and you have three responses: buy from him, sell to him, or ignore him. The third is where the initiative lives.
Down twenty per cent, ask what changed: the business, or the quotation? If the business is intact, that was a mood, and moods come back tomorrow.
Volatility is the service you are not charged for
An emotional partner is not the risk; he is the only source of your return. Without his depressions nothing is ever cheap, and without his manias nothing is ever dear. Complaining about swings is complaining that your one supplier keeps turning up for work.
In the same fund, the holder who treats a drawdown as a disaster sells at the low to the holder who treats it as a delivery window.
Do not let him do your valuation
The discipline sits in the fine print. Using his prices requires a valuation of your own, or you cannot tell a bargain from a trap and contrarianism decays into reflex. Whether he is servant or master depends on whether you brought your own ruler.
It has fallen this far, it must be oversold is not a valuation. It is measuring today's quotation against yesterday's quotation.
How do I use it today?
Where you are: the price is swinging hard and your pulse is following the chart.
Ask first: what is my own valuation, and against it, is today's quote an opportunity, a trap, or noise?
Where it goes wrong: turning ignore him into never looking, so a real deterioration goes unnoticed; or going contrary with no valuation of your own, which is only reflex.
Lines to keep
One of your partners, named Mr. Market, is very obliging indeed.
He is back again tomorrow with a new quotation.
Price fluctuations have only one significant meaning for the true investor.
