Price vs Value

🌱 Beginner★★★★★

Distinguish sharply between market price and underlying business value to avoid overpaying for assets. Understanding this distinction is fundamental to value investing. First independently assess the value, then consider the market price, and only buy when the price is below the value. Prices are determined by the market, while value is determined by the assets themselves. The two often diverge. Key insight: Price and value are fundamentally different concepts that only occasionally converge. Start with a minimal checklist: Is value adequate?; Is value much higher than price?; Is the margin sufficient?.

  • Is value adequate?
  • Is value much higher than price?
  • Is the margin sufficient?
  • Establish adequate value

Avoid misuse: The disparity between price and value can persist for an extended period.

Price is what you pay, value is what you get.

— _Security Analysis_，1934

🏠 Everyday Analogy

Just like shopping for groceries at a market, the imported apples are priced at 20 yuan per jin, but upon closer inspection, you find their quality mediocre. Meanwhile, the local apples at the next stall, priced at 15 yuan per jin, are large and sweet. The price is set by the vendor, but the value is determined by the inherent quality of the apples. Savvy buyers always seek goods whose value exceeds their price.

📖 Core Interpretation

Prices are determined by the market, while value is determined by the assets themselves. The two often diverge.
💎 Key Insight：Price and value are fundamentally different concepts that only occasionally converge. The market sets prices based on sentiment; the analyst determines value based on facts. Your profit as an investor comes from the gap between the two. Never let a rising price convince you that value has increased proportionally.

❓ Why It Matters

Understanding this distinction is fundamental to value investing.

🎯 How to Practice

First independently assess the value, then consider the market price, and only buy when the price is below the value.

🎙️ Master's Voice

The purpose of security analysis is not to determine exactly what a security is worth. It is to establish either that the value is adequate or that the value is considerably more than the market price.
Graham did not seek precise values. He sought to know if price was much lower than value—that was enough to invest.

📚 Case Studies

1
Buffett Buys American Express After Salad-Oil Scandal (1963)
In 1963, American Express plunged after the "salad oil scandal" fraud at Allied Crude tanked confidence. Many investors dumped the stock, fearing ruin. Buffett analyzed AmEx’s core charge-card and travelers cheque franchises and concluded that, despite the scandal, the underlying business and brand loyalty remained extremely strong.
✨ Outcome：Buffett bought about 5% of AmEx at distressed prices. As trust and earnings recovered, the stock multiplied. The episode showed that the market price had diverged from the durable value of the franchise—illustrating that what you pay can be far less than what you get.
2
Washington Post: Buying a $400 Million Business for $80 Million (1973)
During the 1973–74 bear market, shares of The Washington Post Company collapsed. Buffett valued the business—its newspaper, TV stations, and brand—at roughly $400 million, while the market valued it near $80 million. He saw a dominant franchise temporarily mispriced by fear and pessimism.
✨ Outcome：Berkshire invested about $10–11 million, which grew into hundreds of millions over time. The market eventually recognized the company’s true worth. The case shows that price can be far below intrinsic value when sentiment is extreme; disciplined valuation can capture that gap.
