Benjamin Graham on Market Psychology

HIS EARLY LIFE Benjamin Graham was born on l\1ay 9, 1894 in London, the youngest of three children, all boys. His father wa~ in the family business of importing china and bric-a-brac from Austria and Germany. When he was just a year old, the family moved to New York to open an American branch of the firm. Ben began the normal life of a boy in New York, attending P.S. 10 at 117th Street and St. Nicholas Avenue. His father died at only 35, leaving his widow to bring up three boys ages 9, 10, and 1l. Various efforts were made to continue the business but, without an active adult, it failed in little more than a year. Nor did his mother's two-year experiment running a boarding house prove any more successful. When Ben was 13, his mother opened a margin account to buy an odd lot of U. S. Steel. The panic of 1907 wiped out the smail margin account. This was Ben's first contact with the stock market. Despite dwindling family resources, Ben graduated near the top of his class at Boys High School in Brooklyn. A clerical error delayed his scholarship to Columbia for one semester. The need to help support the family forced him to drop his daytime classes to take a full-time job with United States Express. Yet, he continued his studies with such great success that he graduated second in the Class of 1914. During his final month at Columbia, three departments-Philosophy, Mathematics, and English-each invited him to join their faculties as an instructor.

descriptions of each bond in their daily lists of recommendations. After six weeks, Ben was assigned the additional task of writing the daily market-letter for their Philadelphia office. A few months later, World War I broke out and European investors' heavy sales of their American securities caused the panic that forced the New York Stock Exchange to close for several months. When trading resumed on a limited basis, investor confidence gradually returned and the big wartime rise began. His firm, caught shorthanded by this increased activity, used Ben to fill many gaps, including helping the "boardboy" put up stock quotations. Other days he operated the telephone switchboard, helped out in the back office, and even made an occasional delivery of securities. These routine jobs gave Ben an understanding of all aspects of the investment world. When the market settled down, the partners decided to send Ben out to call on customers. This was then a pleasant occupation, because in those days the average businessman was flattered to be called upon by a bond salesman and even his "No" was invariably polite. Although these calls turned out to be fruitless, Ben was learning about the limited understanding most clients had of the securities they bought or owned. Ben began to study railroad reports, then the major industry with bonds outstanding. He applied himself diligently to the then standard textbook: The Principles of Bond Investment by Lawrence Chamberlain.

The investor with a portfolio of sound stocks should expect their prices to fluctuate and should neither be concerned by sizable declines nor become exC£ted by sizable advances. He should always remember that market quotations are there for his convenience, either to be taken advantage of or to be ignored. Sound generalz"zations can be more dangerous than unsound ones because they lure more people into unwarranted actions. The Intelligent Investor Third Edition, 1959 The post-World War II world has been characterized as 'brave' and 'new.' Brave it is, indeed, but we are not positive that it is equally new. We can be skeptical about a complete break with the past. Security Analysis Fourth Edition, 1962 Common stocks have one important investment characteristic and one important speculative characteristic. Their investment value and average market price tend to increase irregularly but persistently over the decades, as their net worth builds up through the reinvestment of undistributed earnings . ... However, most of the time common stocks are subject to irrational and excessive price fluctuations in both directions, as the consequence of the ingrained tendency of most people to speculate or gamble-i.e., to give way to hope, fear and greed.

The present optimism is going to be overdone, and the next pessimism will be overdone, and you are back on the Ferris Wheel-whatever you want to call it--Seesaw, Merry-Go-Round. You will be back on that. Right now, stocks as a whole are not overvalued, in my opinion. But nobody seems concerned with what are the possibilities that 1970 and 1973-1974 will be duplicated in the next five years. Apparently, nobody has given any thought to that question. But that such experiences will be duplicated in the next five years or so, you can bet your Dow] ones Average on that. HB: This has been a most pleasant and stimulative visit. We will look forward to receiving in Charlottesville your memoirs manuscript. Thank you so much, Mr. Graham!

The 1974-75 article — rediscovered and contextualised by Jason Zweig — sets out Graham's framework for assessing whether the stock market as a whole is over- or under-valued. Graham proposes a central-value estimate based on normalised earnings, a quality-adjusted capitalisation rate, and a comparison with bond yields. The output is a single ratio: market price divided by central value. Graham argues that the ratio is a useful signal when it falls well below or above one, and that the investor should adjust his stock-bond mix accordingly. The framework's distinctive feature is that it does not forecast the market's near-term direction. Graham is explicit that the central-value estimate is too coarse to time the market in any short window. Instead, the ratio of price to central value operates as a slow-moving indicator that nudges the investor toward a larger equity allocation when the market is broadly cheap and toward a smaller one when it is broadly dear. The investor's action is incremental, not all-or-nothing. Graham's article applies the framework to the period 1965-1975, showing how the price-to-central-value ratio drifted from expensive in the late 1960s to attractive in the 1974 bear market. The implicit conclusion is that an investor who had followed the framework across the decade would have reduced equity exposure through the 1968-1972 Nifty Fifty peak and increased it through the 1973-1974 bear, ending the decade with a portfolio mix that reflected the changed pricing of equities rather than the changed mood of investors.

Graham's central metaphor in chapter 8 of The Intelligent Investor is the hypothetical "Mr. Market" — a partner who every business day offers either to buy your interest in the enterprise or to sell you more, at a price he himself sets. Mr. Market is emotionally unstable: euphoric on some days, despondent on others, and the quotation he offers swings accordingly. Graham's instruction to the reader is to treat Mr. Market as a servant rather than as a master — to accept his quotations when they are favourable and to ignore him when they are not, but never to let Mr. Market dictate the perceived value of the underlying business. The discipline Graham recommends is to anchor on intrinsic value independently of price. If Mr. Market's quote is well below the analyst's estimate of intrinsic value, the investor buys; if well above, the investor sells or holds; if broadly in line with value, the investor does nothing. The error Graham warns against most often is the mirror-image mistake of treating daily price movement as information — buying because prices are rising, or selling because they are falling, when in fact the underlying business has not changed. Graham's deeper point is psychological. Most investor losses, in his telling, come not from inferior analysis but from capitulating to price as if price were truth. The investor who needs the market to validate his thesis will be whipsawed; the investor who treats the market as an emotionally unstable counterparty can exploit the volatility. Mr. Market is the most enduring image in twentieth-century value investing precisely because it compresses an entire theory of market psychology into a single parable.

The 1955 Graham-Newman annual report, the partnership's report for the year ended January 31, 1955, is the document in which the partnership records its most explicit discussion of the difficulty of finding bargains in a rising market. The report notes that the bull market of the early 1950s had narrowed the universe of undervalued common stocks, and that the partnership's undervalued category had become a smaller fraction of the partnership's total assets as the market's re-rating of the structural discounts had proceeded. The 1955 report's analytical contribution is to make explicit the tension between the partnership's analytical method and the market's general direction: in a rising market, the structural discounts the partnership identifies close more quickly, and the partnership's analytical edge is correspondingly reduced. The report is candid that the narrowing of the edge is the analytical wage for the market's advance, and that the partnership must accept the narrowing as the structural condition of a bull market. The report's discussion of the difficulty of finding bargains is its most instructive passage. Graham-Newman records that the partnership's undervalued positions had been bought at prices the partnership estimated to be below the working-capital value of the underlying businesses, and that the rising market had lifted many of the partnership's holdings above the working-capital floor at which the analytical edge had been identified. The report's instruction is that the partnership's analytical edge in the undervalued category is not a permanent feature of the market; it is a feature of the market's particular condition at the time of purchase, and the partnership must accept that the edge narrows as the market rises. The report is candid that the narrowing of the edge is the analytical wage for the market's general advance, and that the partnership cannot expect to find the same density of structural discounts in a market that has already re-rated them away. The 1955 report's other instructive passage is the partnership's discussion of the special-situations category as the partnership's hedge against the narrowing of the undervalued category. Graham-Newman records that the special-situations positions, held for the closing of defined catalysts, were less affected by the market's general direction than the undervalued positions, because the catalyst's closing was the analytical event the partnership had identified, not the market's general re-rating. The report's instruction is that the special-situations category is the partnership's structural response to the narrowing of the undervalued category in a rising market: when the structural discounts close, the partnership shifts its analytical effort to the catalysts whose closing is not dependent on the market's direction. The 1955 report is, in this sense, the document in which the partnership's working method is most clearly shown to be a response to the market's general condition, and not a fixed recipe that the partnership applies regardless of the market's state.

Graham's 1955 testimony before the U.S. Senate Banking Committee's Stock Market Study is the document in which Graham, summoned to Washington to discuss the state of the equity market, gave his most direct assessment of the market's structure and of the regulator's proper role in it. Graham's testimony opens with the observation that the equity market of 1955 had recovered substantially from the troughs of the 1930s and 1940s, and that the market's recovery had been accompanied by an increase in participation by individual investors who had been absent from the market in the immediate postwar years. Graham's instruction to the Committee is that the market's recovery is, on the whole, a healthy development, and that the regulator's proper role is not to constrain the market's general direction but to ensure that the market's participants are operating honestly, with adequate disclosure, and without the manipulative practices that had disfigured the market in earlier eras. Graham's testimony on the question of market forecasting is the document's most instructive passage. Graham tells the Committee that he does not regard market forecasting as a respectable analytical activity, and that the analyst who claims to forecast the market's general direction is, in his view, claiming a knowledge the analyst does not have. Graham's instruction is that the analyst's proper work is to estimate the value of individual securities, not to forecast the market's direction, and that the analyst who confines himself to the former activity will, over a long horizon, do better than the analyst who attempts the latter. Graham's testimony is, in this sense, an early statement of what later generations would call the efficient-market critique of market forecasting: the market's direction is a function of the aggregate expectations of all participants, and the analyst who attempts to forecast the aggregate expectations is attempting to forecast a forecast. Graham's testimony on the question of margin and leverage is the document's other instructive passage. Graham tells the Committee that the use of margin and leverage by individual investors had, in the 1920s, contributed substantially to the severity of the 1929 crash, and that the regulator's proper role in the postwar market was to maintain margin requirements at a level that would prevent the leverage cycle from repeating. Graham's instruction is that the regulator's margin requirements are the structural protection against the leverage cycle, and that the regulator should resist the pressure to lower margin requirements in periods of market enthusiasm. The 1955 testimony is, in this sense, the document in which Graham's views on the market's structure, the regulator's role, and the proper discipline of the analyst are most directly recorded, and it is the document on which subsequent generations of value analysts have drawn for Graham's most direct statements on the market as a system rather than as a collection of individual securities.

Graham used the hearing to restate the distinction between the defensive investor and the enterprising investor that organized his teaching. The defensive investor, he testified, sought a sound and understandable result with a minimum of effort and risk — a portfolio assembled to hold, not to manage. The enterprising investor was willing to devote real time and study to doing better, and could justify more selective and concentrated commitments. What the distinction did not permit was the middle posture the committee feared the public had adopted: the enthusiasm of the enterprising investor without the corresponding work. Graham's account of the two postures gave the senators a framework for their own question about public participation — the problem was not that ordinary people bought stocks, but that they bought stocks without ever deciding which kind of investor they intended to be.

On the wave of new participants entering the market in 1954 and 1955 — many buying shares for the first time — Graham cautioned the committee against the assumption that the recent past was a sample of the future. The new investors had known only rising prices, he observed, and the confidence that experience produced was precisely the confidence that damage would later exploit. He did not testify that a crash was coming; he declined, characteristically, to predict the market at all. What he offered was the observation that expectations formed in an uninterrupted advance are not evidence about long-run returns, and that the public's introduction to equities through a period of exceptional performance was a hazard in itself. The statement stood as the hearing's clearest warning about extrapolation — the error he considered the most dependable of all the market's recurring mistakes.

Graham's eighth chapter introduces the metaphor that has outlived every other passage in his writing, the allegory of Mr. Market. Mr. Market is a hypothetical partner in a private business who, every business day, offers either to buy your stake or to sell you more, at a price he sets. Mr. Market is emotionally unstable. On some days he is euphoric and names a price well above the value the business would fetch in a sober transaction. On other days he is despondent and names a price well below that value. Graham's instruction to the reader is that the investor is free, on every day, to take Mr. Market's offer, to ignore it, or to make a counter-offer at a price the investor sets for himself. The investor is under no obligation to trade, and Graham's argument is that the investor who feels obliged to trade has misunderstood the relationship. The deeper point of the allegory is that Mr. Market is there to serve the investor, not to instruct him. The investor who lets Mr. Market's quotation govern his view of the value of his stake has ceded to his partner the very authority that, as the owner, he should retain for himself. Graham's prescription is that the investor should form his own view of the value of the business, based on its earnings, its assets, and its dividend-paying capacity, and should treat Mr. Market's quotation as a piece of information about Mr. Market's mood, not as a piece of information about the underlying business. When Mr. Market's quotation is below the investor's estimate of value, the investor can buy from him. When Mr. Market's quotation is above the investor's estimate of value, the investor can sell to him. On every other day the investor can ignore the quotation entirely. This is the chapter Warren Buffett has called the most important passage Graham ever wrote. The chapter's practical implication is that price fluctuation, properly understood, is the investor's opportunity, not his risk. The investor whose stake falls in price has not lost money; he has been offered a chance to buy more at a lower price. The investor whose stake rises in price has not made money; he has been offered a chance to sell at a higher price. The conversion of price fluctuation from risk into opportunity depends, in Graham's account, on the investor having formed an independent view of value. Without that view, the investor is at the mercy of Mr. Market's mood, and the mood is, by definition, unstable. With that view, the investor is the master of the relationship, and Mr. Market's volatility becomes the source of the investor's edge. The eighth chapter is the philosophical hinge of the book, and Graham returns to its lessons in every subsequent chapter on portfolio construction and security selection.
