The History of Value Investing
Value investing is the practice of buying securities for less than they are worth and waiting for the market to recognize the discrepancy. The idea sounds simple. The intellectual framework behind it, built over nearly a century by a succession of practitioners and academics, is one of the most rigorously developed investment philosophies in existence. The history of value investing begins with Benjamin Graham in the aftermath of the 1929 crash and continues through Warren Buffett, Charlie Munger, and a generation of fund managers who have applied and adapted Graham's principles across changing market conditions.
Before Graham: Investing as Speculation
For most of the 19th century and into the early 20th century, the line between investing and speculating was blurred to the point of nonexistence. Investors bought stocks based on tips, insider knowledge, momentum, or promotional materials distributed by company promoters. There was no systematic framework for evaluating whether a stock was cheap or expensive relative to the underlying business.
Some early practitioners did apply analytical rigor. Railroad analysts in the 19th century evaluated track mileage, tonnage, and revenue per mile. Roger Babson, who founded the Babson Statistical Organization in 1904, used statistical methods to forecast market trends. The Dow Theory, developed by Charles Dow (founder of the Wall Street Journal) and refined by William Peter Hamilton and Robert Rhea, attempted to identify market trends through the behavior of the Dow Jones Industrial and Transportation averages.
But these were primarily technical and trend-following approaches. The idea of analyzing a company's balance sheet and income statement to estimate its intrinsic value, and then buying the stock only if the price was substantially below that value, was not practiced in any systematic way before the 1930s.
Benjamin Graham and the Birth of a Discipline
Benjamin Graham was born in London in 1894 and raised in New York after his family emigrated when he was a child. He graduated from Columbia University in 1914, near the top of his class, and entered Wall Street as a bond analyst. By the mid-1920s, he was running his own investment partnership, the Graham-Newman Corporation, and teaching a securities analysis course at Columbia.
The crash of 1929 devastated Graham's portfolio. His partnership lost roughly 70% of its value between 1929 and 1932. The experience was transformative. Graham had considered himself an analytical investor, but the crash revealed that his methods had not been rigorous enough to protect against catastrophic loss.
Out of that experience came "Security Analysis," published in 1934 and co-authored with David Dodd, a colleague at Columbia. The book was dense, technical, and over 700 pages long. It established a systematic method for analyzing stocks and bonds based on financial statements. Graham argued that investors should treat stocks as fractional ownership interests in real businesses, not as trading vehicles. They should estimate the intrinsic value of a business using its earnings, assets, and dividends, and they should buy only when the market price was substantially below that intrinsic value.
Graham introduced the concept of "margin of safety," which became the central principle of value investing. The margin of safety is the difference between what an investor pays for a security and what it is actually worth. By buying with a large margin of safety, an investor creates a buffer against errors in analysis, unexpected business deterioration, and the general unpredictability of the future.
In "The Intelligent Investor," published in 1949 and aimed at a broader audience than "Security Analysis," Graham introduced the allegory of Mr. Market. He asked readers to imagine the stock market as a business partner named Mr. Market, who shows up every day offering to buy or sell shares at a different price. Sometimes Mr. Market is euphoric and offers absurdly high prices. Sometimes he is depressed and offers absurdly low prices. The intelligent investor's job is to take advantage of Mr. Market's mood swings rather than be influenced by them.
Graham's Quantitative Approach
Graham's investment criteria were specific and quantitative. In his later career, he refined his approach into a set of rules that could be applied mechanically. He favored stocks that traded below their net current asset value (current assets minus total liabilities), a metric known as "net-nets." These were companies where the market price was less than the value of the company's liquid assets alone, effectively valuing the ongoing business at zero or less.
He also developed screens based on price-to-earnings ratios, dividend yields, and balance sheet strength. A typical Graham screen might require: a P/E ratio below 15, a price-to-book ratio below 1.5, current ratio above 2, debt less than tangible book value, and a consistent dividend payment history.
Graham's approach was inherently diversified. He did not try to identify the one best stock. He bought baskets of statistically cheap stocks, expecting that the group as a whole would outperform even if some individual positions turned out badly. This probabilistic approach reflected his belief that the future of any individual company was uncertain, but the behavior of a diversified portfolio of cheap stocks was more predictable.
The Graham-Newman Corporation, which operated from 1926 to 1956, compiled an impressive track record. It earned approximately 14.7% annualized returns after fees over its life, significantly outperforming the market during a period that included the Great Depression and World War II.
Warren Buffett: From Graham to Quality
Warren Buffett enrolled in Graham's securities analysis course at Columbia in 1950, after being rejected from Harvard Business School. He later described "The Intelligent Investor" as "the best book on investing ever written." After graduating, Buffett worked for Graham-Newman from 1954 to 1956, learning the mechanical value approach firsthand.
When Buffett started his own investment partnership in Omaha in 1956, he initially applied Graham's methods closely, buying deeply discounted stocks and "cigar butt" companies (businesses that were so cheap they had one last "puff" of value left). His early investments included Dempster Mill Manufacturing, a windmill and farm equipment company trading well below its net asset value, and Sanborn Map Company, where Buffett recognized that the company's investment portfolio was worth more than its entire market capitalization.
The shift began in the 1960s, influenced by Charlie Munger, a lawyer and investor whom Buffett had met in 1959. Munger pushed Buffett away from Graham's strict quantitative approach toward paying fair prices for exceptional businesses. Munger's famous formulation was: "It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price."
Buffett's 1972 purchase of See's Candies through Berkshire Hathaway was a turning point. See's was not a Graham-style net-net. It was a profitable, well-managed business with a strong brand that could raise prices without losing customers. Buffett paid $25 million for a business earning $2 million after taxes, a price Graham might have considered too high. But See's generated enormous cash flows for decades, eventually sending more than $2 billion in pretax earnings back to Berkshire Hathaway.
This evolution from Graham's "buy anything cheap enough" to Buffett's "buy great businesses at reasonable prices" represented the most significant development in value investing since Graham's original formulation. Buffett preserved Graham's core concepts: margin of safety, Mr. Market, the distinction between price and value. But he applied them to a different type of business, one with competitive advantages, pricing power, and long-term durability.
The Academic Challenge
Value investing faced its strongest intellectual challenge from academia in the 1960s and 1970s. The efficient market hypothesis (EMH), developed by Eugene Fama at the University of Chicago, argued that stock prices reflected all available information and that it was impossible to consistently outperform the market through security analysis. This thesis also underpinned the case for index investing.
The EMH directly contradicted the premise of value investing. If markets were efficient, mispriced securities would not exist. Graham's margin of safety would be an illusion. Buffett's track record would be attributable to luck rather than skill.
Fama and his colleague Kenneth French complicated this picture with their 1992 paper "The Cross-Section of Expected Stock Returns," which showed that value stocks (those with high book-to-market ratios) had historically outperformed growth stocks. Fama interpreted this "value premium" not as evidence of market inefficiency but as compensation for risk: value stocks earned higher returns because they were riskier.
Value investors had a different interpretation. Josef Lakonishok, Andrei Shleifer, and Robert Vishny published a 1994 paper, "Contrarian Investment, Extrapolation, and Risk," arguing that value stocks outperformed because investors systematically overreacted to bad news and extrapolated recent poor performance too far into the future. The value premium, in their view, was a behavioral phenomenon that reflected human psychological biases, exactly what Graham had argued decades earlier with his Mr. Market allegory.
Second and Third Generation Value Investors
Graham's students and intellectual heirs extended value investing in different directions. Walter Schloss, who worked alongside Buffett at Graham-Newman, practiced a pure Graham approach for decades, buying statistically cheap stocks and holding diversified portfolios. His fund compounded at 15.3% annually from 1956 to 2002, versus 10.0% for the S&P 500.
Bill Ruane, another Graham student, founded the Sequoia Fund in 1970 at Buffett's suggestion. The fund concentrated its holdings in high-quality companies purchased at reasonable valuations, closer to Buffett's approach than Graham's.
John Templeton applied value principles to international markets, buying stocks in countries that were out of favor with investors. His Templeton Growth Fund returned 14.5% annually from 1954 to 1992.
Seth Klarman, the founder of Baupost Group and author of "Margin of Safety" (1991), focused on distressed debt, special situations, and securities that institutional investors shunned because of complexity or illiquidity. His fund compounded at approximately 20% annually over three decades.
Joel Greenblatt developed the "Magic Formula" approach, which systematically ranked stocks by a combination of earnings yield and return on capital, blending Graham's emphasis on cheapness with Buffett's preference for business quality. His 2005 book "The Little Book That Beats the Market" demonstrated that this formula had dramatically outperformed the market over a 17-year testing period.
The Value Drought and Its Lessons
The decade following the 2008 financial crisis was the most difficult period for value investing in its history. From roughly 2010 to 2020, growth stocks dramatically outperformed value stocks. Technology companies like Apple, Amazon, Google, Microsoft, and Facebook (now Meta) dominated market returns, and their stocks consistently traded at premium valuations that value investors found difficult to justify.
The Russell 1000 Value Index underperformed the Russell 1000 Growth Index by more than 200 percentage points cumulatively between 2007 and 2020. Value-oriented fund managers lost assets as investors moved to growth funds and index funds. Commentators questioned whether value investing was permanently broken, whether the digital economy had made traditional valuation metrics obsolete.
Value investors offered several responses. Some argued that persistently low interest rates had distorted valuations by reducing the discount rate applied to future cash flows, disproportionately benefiting long-duration growth stocks. Others pointed out that value investing had experienced extended periods of underperformance before, notably in the late 1990s during the dot-com bubble, and had subsequently outperformed.
The period from late 2020 through 2022 brought a partial reversal, as rising interest rates and inflation rotated capital toward value stocks. This did not resolve the debate, but it served as a reminder that investment styles move in cycles and that a decade of underperformance does not invalidate an approach that has worked across much longer time horizons.
The Permanent Contribution
Value investing's contribution to finance is not just a set of stock-picking techniques. It is a way of thinking about the relationship between price and value, between market psychology and business reality. Graham's insight that the stock market is a voting machine in the short run and a weighing machine in the long run has been confirmed by every subsequent market cycle. His concept of margin of safety applies not just to stocks but to any investment decision made under uncertainty.
The history of value investing is a history of practitioners who took Graham's framework and adapted it to their own circumstances, their own markets, and their own temperaments. The common thread is intellectual honesty about what a business is worth, combined with the discipline to buy only when the price is right. That combination is no easier to execute today than it was when Graham published "Security Analysis" ninety years ago.
