Value Investing: Finding Companies Worth More Than Their Price
Benjamin Graham, refined by Warren Buffett · The Intelligent Investor (1949) (1949)
Value investing is the practice of buying stocks at a price below their intrinsic value—calculated from assets, earnings, dividends, and growth prospects—and holding them until the market recognises the true worth.
Core Concepts
The Problem
Markets are not always efficient in the short run; prices can deviate widely from the underlying economic value of a business due to fear, greed, or neglect.
The Claim
An investor who rigorously studies financial statements and estimates intrinsic value can identify mispriced securities, buy them with a margin of safety, and achieve superior long-term returns.
Key Evidence
- •Berkshire Hathaway’s long-term outperformance of the S&P 500.
- •Ac ademic studies showing that low price-to-book and low price-to-earnings stocks have historically outpeformed growth stocks.
Practical Implication
Patience and detailed research are more important than timing the market. Investors should think like business owners, focusing on what they actually get for their money.
Nuance & Limits
Value traps—stocks that look cheap but are actually declining businesses—are a major risk. Successful value investors must also assess qualitative factors like competitive advantage and management integrity.

Margin of safety is the central concept of value investing: buying at a price sufficiently below intrinsic value to absorb errors in estimation or adverse events.
Gaps
- ⚠ Does value investing still work in an era of passive funds and instant information?
- ⚠ How does one reliably estimate intrinsic value for technology companies with few tangible assets?
