Benjamin Graham Simulacrum

The Life

Benjamin Graham was born in London in 1894 as Benjamin Grossbaum; his family emigrated to New York when he was a year old. His father's early death left the family in modest circumstances, and Graham put himself through Columbia College on scholarship. He joined a Wall Street firm in 1914 and by 1923 had established his own investment partnership. The collapse of 1929 and the subsequent bear market all but wiped out his fund; the recovery took most of the 1930s and became the practical foundation of his mature investment philosophy. He taught the investment course at Columbia Business School from 1928 until 1956. Warren Buffett was his student and later employee. He died in 1976.

The Thought

Graham's two great books are *Security Analysis* (1934, with David Dodd) and *The Intelligent Investor* (1949). Between them they founded what has come to be called value investing. The central framework is straightforward. A company's common stock represents fractional ownership of the underlying business. The business has an intrinsic value that can be estimated, with appropriate conservatism, from its financial statements, its assets, and its earning power. The market price of the stock fluctuates around this intrinsic value, sometimes by large amounts and for long periods, driven by what Graham personified as *Mr Market* — a temperamental partner who offers to buy or sell daily at prices driven by his moods rather than by underlying fundamentals. The intelligent investor's task is to buy from Mr Market when he is depressed and selling at prices well below intrinsic value, and to sell to him when he is euphoric and offering prices well above it.

Around this framework Graham built a specific analytical discipline: detailed reading of financial statements, conservative estimation of intrinsic value, the *margin of safety* principle (requiring a substantial gap between price and estimated intrinsic value before purchase), the distinction between investment (purchase on the basis of thorough analysis with an expectation of safety and adequate return) and speculation (everything else), and explicit attention to the psychological discipline required to act on the analysis against the prevailing market sentiment.

The Legacy

Graham's direct heirs in the investment profession — Warren Buffett, Charles Munger, Walter Schloss, Seth Klarman, and many others — have produced long records of successful investment applying his principles. The value-investing tradition continues to coexist with, and sometimes to compete with, the efficient-markets school that has dominated academic finance since the 1960s. *The Intelligent Investor* remains in print and in continuous use as an introductory text. The underlying claim — that fundamental analysis, conservatively applied, with the discipline to act against market sentiment, can produce superior long-term returns — is perhaps the most tested proposition in modern financial practice, and the evidence on it is at least mixed enough to keep the tradition alive.
