📖Benjamin Graham

The Mr. Market Parable

🌱 Beginner★★★★★

The market is your servant, not your master. Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong. Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside. In The Mr. Market Parable, Benjamin Graham focuses on the gap between price and value. Key insight: Market prices are offers to be evaluated, not commands to follow. Valuation is like buying a house: the asking price reflects mood, but true value comes from structure, location, and long-term utility.

Avoid misuse: Confusing a low price with true cheapness

💬

Imagine having a partner named Mr. Market who offers to buy or sell shares at a different price every day. Sometimes his price is reasonable, but often it is absurdly high or low. You are free to ignore him.

— _The Intelligent Investor_，1949

📖 Core Interpretation

In The Mr. Market Parable, Benjamin Graham focuses on the gap between price and value. Returns come from paying less than what a business is worth, not from guessing short-term market moves.
