📖Benjamin Graham

Sell When Overvalued

🌿 Intermediate★★★★☆

Sell when price exceeds intrinsic value. 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 Sell When Overvalued, 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. Key insight: Discipline in selling preserves gains and reduces risk.

Avoid misuse: Confusing a low price with true cheapness

💬

The investor should sell when his stock has risen to a level where the price no longer represents a bargain relative to its intrinsic value.

— _The Intelligent Investor_，1949

🏠 Everyday Analogy

Valuation is like buying a house: the asking price reflects mood, but true value comes from structure, location, and long-term utility. Good assets still need sensible prices.

📚 Case Studies

1
Net-Current-Asset Bargains (1934)
Graham invested in very small firms selling below net current asset value, often ignored by institutions.
✨ Outcome：Many such tiny companies liquidated or recovered, producing substantial gains and validating his preference for smaller, statistically cheap stocks.
2
GEICO Investment (1948)
Graham bought a large stake in relatively small, fast-growing insurer GEICO when it was still obscure.
✨ Outcome：GEICO became a much larger, highly profitable company, generating one of Graham-Newman’s best long-term returns and illustrating the payoff from smaller growth franchises.
