André Kostolany: The Old Master Who Made Two Fortunes Buying What Nobody Wanted

In the autumn of 1996, a ninety-year-old Hungarian-born Frenchman in a wheelchair watched the cable news from his Paris apartment and laughed. The Franco-Russian Treaty had just been ratified. Russia, eager to rejoin the international capital markets after the collapse of the Soviet Union, had agreed to repay the Tsarist bonds that the Bolsheviks had repudiated in 1917. For seventy-nine years, those defaulted bonds had been treated as worthless paper, traded only by collectors of historical curiosities and a small handful of speculators willing to wait. The old man in the wheelchair was the last and the most patient of them.

He had bought his first Tsarist bonds in 1989, when Mikhail Gorbachev’s perestroika reforms suggested that the Soviet Union might one day need to make peace with its old creditors. He had paid roughly five French francs each for paper with a face value of five hundred. He had invested forty thousand Deutschmarks in total. Most of his colleagues thought he had finally lost his mind. He had been buying defaulted sovereign bonds for half a century by then, and not all of his trades had worked.

By the time the settlement landed in his account, his forty thousand Deutschmarks had become four million.

“For me, who bought at five francs,” he later wrote in his column for Capital magazine, “it means a profit of almost six thousand percent.”

The man was André Kostolany, and the Czar bond coup was not even the biggest trade of his career. It was the second-biggest. The biggest had been forty-six years earlier, when he bought defaulted Weimar-era German bonds at twenty-five percent of par and held them until West Germany honoured them in the early 1950s, multiplying his stake one hundred and thirty-nine times. Between those two trades stretched a life that had crossed two world wars, three countries, four languages, and seventy years of European stock market history. He died in Paris three years after the Czar bond settlement, at the age of ninety-three. To the German investing public, who knew him simply as der Altmeister, the Old Master, he was the closest thing post-war Europe had to its own Warren Buffett. Outside German-speaking countries, almost nobody had ever heard his name.

Kostolany never tried to hide what he was. He was a speculator, he said so on the first page of every book he wrote, and he believed speculation was an art rather than a science, closer in spirit to philosophy and chess than to economics or accounting. His method was almost comically simple in summary: read everything, think for yourself, buy what nobody wants, hold it for years, ignore the noise. The summary, of course, missed the point. The method took him seventy years to develop, cost him two fortunes along the way, and worked because he had built up an internal model of how human crowds behaved that almost nobody else of his era could match.

The popular German nickname he disliked was der Bonvivant der Börse, the bon vivant of the stock exchange. He preferred Spekulant, plain and unromantic. He travelled constantly, kept apartments in Paris and Munich and a holiday house on the Côte d’Azur, attended the Vienna Opera Ball every year, listened to Richard Strauss religiously, and refused on principle to be photographed at his desk. He gave seminars to packed lecture halls in Munich and Frankfurt into his nineties, where he would lean on his cane, fix the audience with a half-amused stare, and tell stories about losses he had taken in 1930 that the average German auditor had not yet been born to witness.

Budapest, 1906

André Bartholomew Kostolany was born on the ninth of February, 1900 and six, in Budapest, then the second capital of the Austro-Hungarian Empire. His parents were a wealthy industrialist Jewish family who had converted to Roman Catholicism. He was the youngest of four children, and by every account the most independent-minded of them.

The Budapest of his childhood was one of the great financial cities of Europe. The Budapest Stock Exchange traded grain, currencies, sovereign debt, and the equity of the Empire’s industrial concerns. The young André was, by his own later admission, paying attention to currency markets by the age of twelve. By seventeen, he had used twenty US dollars his father had given him to make his first stock investment. When he eventually wrote his autobiography, he described his earliest financial memories not in terms of any particular trade but in terms of overhearing his father’s friends arguing about the krone, the rouble, and what the Habsburgs would do next.

He went to university in Budapest to study philosophy and the history of art, the two subjects that genuinely interested him. He had no intention whatever of pursuing a career in business. The decision, however, was not his. His father, who had read his son’s restlessness more accurately than the son had, decided in 1924 that André would be sent to Paris to learn the business of stockbroking. The arrangement had already been made with an old family friend, a successful Parisian stock market operator named Adrien Perquel.

Kostolany never forgave the decision and, in another sense, never stopped being grateful for it. He arrived in Paris in 1924, eighteen years old, fluent in three languages, with a freshly broken heart for the philosophy professorship he had been promised and a deep, instinctive hostility to the world of stockbroking he was being shoved into.

Paris, 1924

The Paris of 1924 was the financial capital of continental Europe. The Paris Bourse, with its great neoclassical Palais Brongniart in the second arrondissement, traded equities, sovereign debt, currencies, and commodities for half the world. Reparations from Versailles still flowed through the city’s banks. The German mark was being stabilised after the hyperinflation. Russian Tsarist bonds, repudiated by the Bolsheviks seven years earlier, still traded at minor fractions of par. The world had not yet decided whether the long peace of the 1920s was real or whether the next war was already inevitable.

Kostolany, by his own account, despised it. The Paris Bourse was loud, the brokers were vulgar, the work was repetitive. He was an office boy at first, then a junior broker, and by the late 1920s he had moved to Amerongen and Compagnie, a small private bank that handled international securities. The pay was reasonable. The work bored him.

What did not bore him was watching. Kostolany would later say, with the benefit of seventy years of hindsight, that the apprenticeship in Paris was the most valuable thing his father ever did for him. He had time, in those years, to observe the way the Bourse breathed. He watched bonds rally on rumour and crash on confirmation of the same news. He watched currencies move on speeches. He watched, most importantly, the way the brokers and the wealthy clients above them behaved when they were winning and when they were losing. He concluded, by about 1927, that the academic theory of efficient markets bore almost no relation to what actually happened on a trading floor. The market was a mood, a herd, a fever, with occasional patches of cold rationality. The men who made money over decades, he decided, were the ones who could tell which one was happening at any given moment.

The 1929 Crash and the Lesson That Followed

By 1928 Kostolany was twenty-two years old, ambitious, and increasingly convinced that the European and American bull market had become detached from any plausible economic reality. He began building short positions in equities through 1928 and the first half of 1929. His colleagues laughed at him. He held.

When the New York Stock Exchange collapsed in October of 1929, the European markets followed. Kostolany, by various accounts, made approximately two hundred thousand US dollars on those short positions, a figure that would correspond to roughly four million dollars in present-day terms. He was twenty-three. It was the trade that should have made his career.

It nearly destroyed him.

The lesson that almost no biography of Kostolany emphasises strongly enough is what happened next. Encouraged by the success of 1929, Kostolany attempted to repeat the same playbook the following year. He stayed short. He stayed short through 1930, when the market had a sharp bear-market rally. The rally went against him violently. Within twelve months of his first great triumph, he had been wiped out completely. Not partially, not painfully. Completely. The two hundred thousand dollars was gone, and so was the youthful confidence that had earned it.

This is the experience that, more than any other, shaped the man Kostolany would become. He spent the next decade rebuilding from almost nothing. He worked harder. He read more. He gave up the certainty that any single market view, no matter how correct in the past, would automatically be correct again. He started writing in his private journals, decades before he would publish a word, the aphorisms that would later make him famous in German-speaking Europe. What everybody knows is no longer worth knowing. The stock market is a barometer of the future, not of the present. You can win, but you have to lose.

He told his readers, fifty years later, that the second bankruptcy — the one in 1930 — had been worth more to him than the first triumph. The first had taught him he had a gift. The second had taught him the gift was nothing without humility.

1940: Vigo

By the late 1930s, Kostolany had rebuilt his fortune and his standing. He was a working speculator in Paris with a comfortable apartment and a small but loyal client base. He was also a Jewish-born man in a Europe that was about to be invaded by the Nazis.

The story of his escape, as he later told it, has the kind of dramatic precision that biographers often distrust until they find corroborating evidence. He claimed that a business associate approached him in early 1940 asking him to compile a list of promising European stocks, on the theory that the imminent German occupation of France would be brief and the markets would soon recover. Kostolany pressed the man on his information sources. When he understood that the occupation was effectively a certainty, he politely agreed to compile the list, then went home, packed a single bag, drove south to the Spanish border, and boarded a ship from the port of Vigo bound for the United States. He was thirty-four years old. He had abandoned almost everything he owned in Paris.

The Germans entered Paris on the fourteenth of June, 1940. Kostolany was already at sea.

From 1941 to 1950, Kostolany lived in New York City, where he served as the general director and president of the G. Ballai and Company Financing Company, a small investment firm specialising in European securities. He worked steadily. He admired the dynamism of American capitalism. He never quite settled. He told friends, decades later, that New York had been a wonderful school but never a home. The moment the war was over and Europe was safe again, he wanted to be back on the Paris Bourse he had spent fifteen years insulting.

The Young Bond Coup, 1948–1953

Kostolany returned to Paris in 1950. The continent he came back to was unrecognisable. France was still on rationing. The German economy was a smoking ruin. The Marshall Plan was beginning to flow. The deutsche mark had been introduced two years earlier as a desperate attempt to stabilise the Western occupation zones. Almost nobody in Paris believed that Germany would ever again be a serious investment destination.

Kostolany believed exactly the opposite. He had spent the war years in New York reading German newspapers and German economic literature, and he had concluded that the German people had a particular industrial and intellectual capacity that would, given any sustained period of peace, rebuild the country into one of the world’s leading economies. He coined a phrase for it that became famous in his later writing: he had what he called fundamentals on his side. He believed in the German recovery before there was any visible evidence of one.

The trade vehicle he chose was, characteristically, the most despised security in continental Europe. The Young Bonds were German government bonds issued in 1930 as part of the Young Plan reparations restructuring, denominated in foreign currencies, and held principally by foreign investors. Adolf Hitler had defaulted on them in the 1930s, declaring them illegitimate obligations of a Weimar government he refused to recognise. Through the Second World War and into the late 1940s, the Young Bonds traded on the Paris Bourse and elsewhere at twenty-five percent of par, sometimes lower. Most holders had given up on them entirely.

Kostolany bought aggressively. His friends and colleagues, many of whom had themselves lost money on Young Bonds in the 1930s, told him plainly that he was wasting his money. He held. In 1953, the Federal Republic of Germany, in a deliberate act of post-war financial rehabilitation, agreed under the London Debt Agreement to honour the pre-war foreign debt obligations of the Reich. The Young Bonds were repaid at one hundred percent of par, with significant accrued interest in some tranches.

Kostolany made approximately one hundred and thirty-nine times his money. The trade took roughly five years. It was the foundation on which the rest of his life would be built.

The Wirtschaftswunder Years

The Young Bond profits gave Kostolany the capital base to take serious positions in the equity markets of the 1950s. Through the decade he became, in effect, a private participant in the German Wirtschaftswunder, the economic miracle that saw West German GDP grow at an average rate above eight percent per year between 1950 and 1960.

One trade from this period that has entered Kostolany legend, although it is sourced principally to a single later account, is his position in Chrysler Corporation shares. According to that account, Kostolany acquired Chrysler at around three US dollars per share in the early post-war period and rode the position to roughly one hundred and fifty dollars during the 1950s as the American automaker rebounded on European export demand. The detail of the trade is hard to verify against contemporary records, and the price levels cited may be split-adjusted approximations rather than literal closing quotes. What is unambiguous is that Kostolany made meaningful money on American industrials in the same period in which he was rebuilding Germany. His geographic neutrality was one of his quiet strengths. He had no patriotic loyalty to any particular market.

By the early 1960s he had relocated his principal residence to Munich, married for the second time to Françoise Russell, and bought the holiday house on the Côte d’Azur that would feature in dozens of his later columns. He was, by his own description, a financially independent speculator with no clients, no boss, and no obligations beyond his own curiosity. He was also, at fifty-eight, becoming bored.

The Birth of “Kostolany the Writer”

In the late 1950s Kostolany consulted a psychologist, by his own account, about a creeping sense of restlessness. The psychologist asked him what he had always wanted to do with his life. Kostolany, who had been a philosophy student before his father redirected him at eighteen, answered that he had wanted to write.

The psychologist suggested that he should.

His first book, Der Friede den der Dollar bringt (The Peace That the Dollar Brings), appeared in 1957. It sold modestly. He kept writing. By 1960 he had begun contributing a column to the French magazine La Vie Française. In 1964, the German monthly Capital approached him about writing a regular column on the stock market. He accepted. The column ran continuously, every month, from 1964 until his death in 1999, a stretch of thirty-five years. Across that period he published exactly four hundred and fourteen columns.

The Capital column made Kostolany a household name in German-speaking Europe in a way that no other speculator before or since has ever quite matched. His prose was warm, witty, anecdotal, and merciless about pomposity. He wrote about specific trades, but he also wrote about Mozart, Strauss, Vienna, his second wife, his cigars, his contempt for academic economists, his suspicion of central bankers, and the basic uselessness of trying to predict the market over short horizons. He was, in effect, the first European financial writer to treat the stock market as a subject worthy of literary prose. He was Michel de Montaigne with a portfolio.

By the 1970s he had published several books. By the 1980s, with German retail equity ownership beginning to grow under Helmut Kohl’s reforms, his books were appearing on bestseller lists. By the time he died, his thirteen titles had sold more than three million copies across German, French, Spanish, and Chinese editions. Almost none of them were ever translated into English. To this day, an Anglophone reader who wants to read Kostolany has to use a translation service or learn German.

“Buy stocks, take sleeping pills, and stop looking at them. After many years, you will see how rich you have become.”

— André Kostolany

The Egg, the Dog, and the Two Hands

Kostolany’s gift, the one that made him a legend in Germany rather than merely a successful speculator, was his ability to translate complicated market dynamics into images a Frankfurt dentist or a Munich shopkeeper could understand and remember.

The most famous of these images was the dog and its master. The economy, Kostolany wrote, is the man walking calmly down a country road. The stock market is the dog on the lead. The dog runs ahead, then drops back, then darts into the bushes, then sprints in circles. Sometimes the dog seems to be far ahead of the master. Sometimes it falls a long way behind. Over time, however, the dog always returns to the master’s side. The lesson, he insisted, was not that the dog’s behaviour was unimportant, but that the master’s pace was the only thing that mattered for the long-term direction. The economy walked. The market jumped around. Anyone trying to predict the dog’s next two metres of movement was wasting their time. Anyone failing to notice that the master had changed direction was about to lose money.

The second great image was the Egg. Kostolany described the market as moving in cycles shaped like a vertical egg, oscillating through six sentiment phases: depression, hope, optimism, euphoria, panic, and despair. The Egg, he said, never broke. The wise speculator’s job was to identify which phase the egg was currently passing through and act counter to the prevailing emotion. Buy in despair. Hold through hope. Sell in euphoria. Stay out during panic. The metaphor was almost embarrassingly simple, which was exactly why German retail investors loved it.

The third great image was the two kinds of hands. The market, Kostolany said, was always a struggle between zittrige Hände, shaky hands, and hartgesottene, firm or hard-boiled hands. The shaky hands were the small investors, the leveraged traders, the people who would sell into any meaningful drawdown because they could not afford to lose more. The firm hands were the long-term investors, the patient speculators, the people who had bought with money they could afford to lose and who could therefore hold through any storm. Stocks, in his framework, were always migrating from one to the other. A bull market was the slow process of stocks moving from firm hands into shaky hands at ever-rising prices. A bear market was the violent process of stocks moving from shaky hands back into firm hands at ever-falling prices. The cycle, he said, was as old as markets and would never end.

It is the same insight that George Soros articulated as reflexivity, that Howard Marks built Oaktree around as second-level thinking, that Allan Gray taught his protégés to call letting your bullish juices flow, and that Warren Buffett summarised in the maxim about being fearful when others are greedy and greedy when others are fearful. Kostolany arrived at it independently, in a Munich apartment, writing for a German monthly magazine, several decades before behavioural finance became a recognised academic field.

The Czar Bond Coup, 1989–1996

By the late 1980s, Kostolany was past eighty and had been a working speculator for sixty years. He had, by his own admission, made his fortune several times over. He no longer needed to take large positions. He took one anyway.

The Tsarist bonds had been a curiosity on the Paris Bourse for seventy years. Issued by the Russian Empire between roughly eighteen twenty-two and 1910, denominated in French francs, and held principally by French families who had inherited them from grandparents ruined in the Bolshevik repudiation of 1917, they traded for almost nothing. Most owners thought of them as decorative paper rather than securities. A small handful of speculators traded them on the theory that some future government in Moscow might one day, somehow, settle them.

Kostolany had been watching Mikhail Gorbachev’s perestroika with intense interest from 1985 onwards. He concluded by 1989 that the Soviet system was finished, that some form of post-Soviet Russia would emerge, and that any post-Soviet Russia attempting to rejoin the international capital markets would have to settle the old Tsarist debt as a precondition. He bought the bonds at five French francs each, against a face value of five hundred. He invested forty thousand Deutschmarks. The position was small relative to his net worth and enormous relative to the open market for the bonds.

The Soviet Union dissolved in 1991. The Russian Federation, under Boris Yeltsin, signed a Franco-Russian Treaty in February of 1992 that committed Moscow to address the old debts. The actual settlement took several more years to negotiate. In 1996, with Russia preparing its first post-Soviet Eurobond issue, the Paris-Moscow accord was finalised. The Tsarist bonds were repaid at one hundred percent of nominal value.

Kostolany’s forty thousand Deutschmarks had become four million. He was ninety years old. He wrote it up, deadpan, in his next Capital column. The German investing public, who had spent thirty years reading him explain that patience and contrarian thinking would always pay eventually, treated the trade as the final, definitive proof.

1999: The Last Warning

By the late 1990s, Kostolany was in a wheelchair, partially deaf, and still writing his column. He had been correct about the German Neuer Markt as early as 1998, when he appeared on a German talk show to warn that the surge in technology stocks on the new Frankfurt growth segment would end in tears. The studio audience laughed. The other panellists patronised him as a senile relic of a previous era who did not understand the New Economy.

Kostolany did not back down. He repeated the warning, in his typical style, that he had been speculating since 1924, had seen exactly this kind of euphoria three times before in his life, and that all three had ended badly. There will be a bloodbath, he said. The studio audience laughed again. His column for that month, in Capital, repeated the warning in print.

He died in Paris on the fourteenth of September, 1999, two and a half months before the Neuer Markt peaked and several months before the global tech bubble burst. The bloodbath he had predicted on television arrived precisely on schedule. The Frankfurt growth segment was eventually closed entirely in 1999, having lost the substantial majority of its peak market capitalisation.

His final book, Die Kunst, über Geld nachzudenken (The Art of Thinking About Money), was published shortly after his death and became one of the bestselling investment books in German history. He had written it from the wheelchair, dictating most of it to his editors, in the last full year of his life.

What We Cannot Know

An honest profile of Kostolany has to acknowledge what is unverifiable about him. He was, by his own choice, a man whose public persona was carefully crafted and whose private finances were almost completely opaque. He never disclosed his net worth. His estate was not publicly inventoried. He told stories about his trades in his columns and books, but the stories were almost always told in retrospect, decades after the fact, with the dramatic emphasis of a master raconteur rather than the precision of a fund manager’s quarterly letter.

Some of the figures attributed to him are therefore approximations. The two hundred thousand dollars from the 1929 short trade comes principally from his own later accounts, and the equivalent in present-day dollars depends on which inflator you use. The Chrysler trade of three to one hundred and fifty dollars per share appears in some later sources but is difficult to pin to specific contemporary stock quotes. The four million Deutschmark Tsarist bond payout is well-documented, including in Kostolany’s own column written at age ninety, and is corroborated by the broader published record of the 1996 Paris-Moscow accord.

What is unambiguous is the public record. Seventy years of trading. Two documented bankruptcies. Two enormous defaulted-bond coups, decades apart, executed on the same playbook. Four hundred and fourteen monthly columns in Capital, the exact number archived. Thirteen books with combined sales of more than three million copies. A correct call on the Neuer Markt, made in front of a hostile live studio audience, six months before the peak. A career that crossed two world wars and survived both.

The figure that mattered to him in the end was not his net worth. It was the four hundred and fourteen columns, and the millions of small German and French investors who had read those columns and learned, slowly, over decades, to think the way he thought. He had outlasted the old man’s natural vanity about his bank account. He died believing that the most valuable thing he had compounded over seventy years was not his capital but his readers.

What André Kostolany Teaches

The first lesson is the one he learned the hard way in 1930: that the second great trade is the one that destroys you. Kostolany made his name shorting the 1929 crash, and he was wiped out within twelve months trying to repeat the same position into the 1930 bear-market rally. The lesson he extracted, and repeated for sixty years afterwards, was that no individual market view, however correct it had been before, could be trusted to be correct again automatically. Markets change. Crowds change. The conditions that made a trade work the first time are almost never identical the second. The young trader who has just had a brilliant winner is, for the next eighteen months, the most dangerous person in his own portfolio.

The second lesson is the value of reading what nobody else is reading. Kostolany made the two largest trades of his life on defaulted sovereign bonds — first the German Young Bonds, then the Tsarist bonds — that almost everyone else considered worthless paper. The trades were not technically difficult. The bonds were available on public exchanges. Anyone could have bought them. Almost nobody did, because almost nobody had read the political and economic histories carefully enough to see that the issuing governments would, eventually, need to settle. Kostolany had read those histories, slowly, in three languages, over decades. The trade was not a piece of brilliance. It was the visible tip of a very long, very patient apprenticeship in European political economy.

The third lesson is the art of waiting. Both of Kostolany’s signature coups required holding for between five and seven years against the consensus, with no immediate confirmation that the thesis was correct. The Young Bonds took five years from his first purchases in the late 1940s to the London Debt Agreement of 1953. The Tsarist bonds took seven years from 1989 to the Franco-Russian settlement of 1996. Kostolany did not have private information that the settlements were coming. He had a thesis, a margin of safety so wide that even partial settlement would still produce extraordinary returns, and the patience to wait. That patience, he said in old age, was the single hardest skill to teach a young speculator. It could not be taught. It could only be lived.

The fourth lesson, the deepest, is the one buried in the Egg and the dog and the two hands. Kostolany believed that the stock market was, ultimately, a barometer of human emotion rather than of economic fact. Roughly ninety percent of short-term price movement, he wrote in the 1960s, came from psychology, not from fundamentals. This insight, which now looks ordinary in the wake of Daniel Kahneman and Richard Thaler and forty years of behavioural finance research, was almost heretical when Kostolany first articulated it. He arrived at it not from a laboratory but from sixty years of watching human beings buy too much when they were happy and sell too much when they were frightened. The market, in his eyes, was a giant mood-ring. The serious speculator’s job was to read the mood, ignore the noise that other people called fundamentals, and bet calmly against whatever the crowd was certain about today.

He spent seventy years proving the framework worked. He paid for the proof twice with bankruptcies. He left behind four hundred and fourteen monthly columns, thirteen books, and a quiet army of European retail investors who, decades later, still buy when others panic because of an old man in a wheelchair who taught them to think for themselves.

Frequently Asked Questions

Who was André Kostolany?

André Kostolany (1906–1999) was a Hungarian-born stock-market speculator and financial writer who spent most of his life in France and Germany. Across a seventy-year career he made his name on contrarian trades in defaulted sovereign bonds, suffered at least two complete bankruptcies, and became Germany’s most famous and most quoted investing voice through forty years of monthly columns in Capital magazine. He is widely known in German-speaking countries as der Altmeister der Börse, the Old Master of the Stock Exchange.

How did André Kostolany make his money?

Through speculation, defined in his sense as taking deliberate, contrarian positions against the consensus and holding them for long periods. His two signature trades were both defaulted sovereign bonds: the German Young Bonds, bought at twenty-five percent of par from roughly 1948 onwards and redeemed at par in 1953 for approximately one hundred and thirty-nine times his initial outlay; and the Tsarist Russian bonds, bought at one to five percent of par from 1989 and settled at par in 1996, turning forty thousand Deutschmarks into four million. He also profited from the German Wirtschaftswunder through equity positions in the 1950s, and from a successful short of the 1929 Wall Street Crash that earned roughly two hundred thousand US dollars before he gave most of it back the following year.

Was Kostolany a value investor?

No, and he refused the label. He called himself a Spekulant, a speculator. He had no patience for the rigorous fundamental analysis associated with Benjamin Graham and Warren Buffett, although he respected both men. His approach was psychological and historical rather than financial. He looked for situations where the market price was driven entirely by sentiment, fear, or political prejudice, and where his reading of the underlying political and economic forces suggested that sentiment would eventually have to reverse. The defaulted-bond trades are the clearest examples. The bonds had no current cash flows and no near-term catalyst, which is why traditional value investors avoided them. Kostolany bought them anyway because his thesis was about politics and patience, not about cash flow.

What was Kostolany’s “Egg Theory”?

The Egg, or Eierdiagramm in German, was Kostolany’s metaphor for the cyclical movement of stock markets through six emotional phases: depression, hope, optimism, euphoria, panic, and despair. The cycle, in his telling, was eternal and inescapable. The wise speculator’s job was to identify which phase the market was currently in, then act against the prevailing emotion: buy during depression and despair, hold through hope and optimism, sell during euphoria, and avoid panic entirely. The Egg was deliberately simple because Kostolany was writing for retail investors, not for institutional analysts. The simplicity was the point.

What is the “dog and master” analogy?

Kostolany’s most famous image. The economy, he said, is the man walking down a country road at a steady pace. The stock market is the dog on the lead. The dog runs ahead, drops back, darts off into the bushes, sometimes seems entirely lost. Over time, however, the dog always returns to the master’s side. The lesson is that short-term market movements are largely random and emotional, while the long-term direction is set by economic fundamentals. Investors who try to predict every twitch of the dog waste their time. Investors who pay attention to the master’s pace and direction tend to be right over five-to-ten-year horizons.

Did Kostolany really go bankrupt twice?

Yes, by his own repeated admission. The first major bankruptcy came in 1930, immediately after his triumphant short of the 1929 crash, when he tried to repeat the same bearish positioning and was caught by the bear-market rally of that year. He referred to a second wipeout in later writings, although the date and circumstances of the second one are less precisely documented than the first. He treated both episodes openly in his books and columns and considered them essential to understanding why his later approach worked. He often said the bankruptcies had taught him more than the triumphs.

Why is Kostolany so famous in Germany but unknown in English?

Almost entirely because of language. Kostolany wrote his books and columns in German and French, and only a handful of his thirteen books were ever translated into English. The German Capital column ran for thirty-five years and made him a household name in Frankfurt and Munich. The Anglo-Saxon investment world, dominated by Wall Street and the City of London, never had reliable access to his work, and the small number of English-language Kostolany articles that exist are mostly secondhand summaries written by Continental Europeans for non-German audiences. He remains one of the great twentieth-century speculators, almost completely missing from the standard English-language canon.

What is Kostolany’s most quoted line?

His most-quoted line in German is the dictum about sleeping pills: “Buy stocks, take sleeping pills, and stop looking at them. After many years, you will see how rich you have become.” The line is partly a joke about his own pleasure-loving lifestyle and partly a serious instruction about the danger of overtrading. He believed that the typical retail investor lost money primarily through emotional reactions to short-term price movements, not through poor stock selection. Removing the temptation to react, in his view, was usually worth more than improving the stock-picking process.
