Why Edward Thorp Owns Only Berkshire Hathaway

Much of what I read was dross but, like a baleen whale filtering the tiny nutritious krill from huge volumes of seawater, I came away with a foundation of knowledge. During the long ride back I wondered how my research into the mathematical theory of a game might change my life. In the abstract, life is a mixture of chance and choice. Chance can be thought of as the cards you are dealt in life. As a result, chance offered me a new set of unexpected opportunities. I also believed then, as I do now after more than fifty years as a money manager, that the surest way to get rich is to play only those gambling games or make those investments where I have an edge.

As a result, between the ages of five and seven, I carried around adult – looking books and strangers wondered if I actually knew what was in them. My mother was fully occupied by the new baby and was even more focused on him when, at six months of age, he caught pneumonia and nearly died. This left me much more on my own and I responded by exploring endless worlds, Retail foreign exchange trading both real and imagined, to be found in the books my father gave me. This trait was useful later in life when everybody “knew” you couldn’t beat any games in Las Vegas and everybody “knew” the markets were efficient and you have no edge. A trait that showed up at about this time was my tendency not to accept anything I was told until I had checked it for myself.

Making money confirmed my theories by showing that they worked in the real world. Warren began to invest while still a child and spent his life doing it remarkably well. My discoveries fit in with my life path as a mathematician and seemed much easier, leaving me largely free to enjoy my family and pursue my career in the academic world. A child of the Great Depression, legendary mathematician Edward O. Thorp invented card counting, proving that you could do the seemingly impossible—beat the dealer at the blackjack table—and in doing so launched a gambling renaissance.

Could my methods for beating games of chance give me an edge in the greatest gambling arena on earth, Wall Street? I began to teach myself about the financial markets, lighting my way with an unusual lamp, the What is Infinox knowledge I had gained from gambling games. It wasn’t the money that drew me to blackjack. What intrigued me was the possibility that merely by sitting in a room and thinking, I could figure out how to win.

He learned Fortran in order to program the equations needed for his theoretical research model on the probabilities of winning at blackjack. Thorp analyzed the game of blackjack to a great extent this way, while devising card counting schemes with the aid of the IBM 704 in order to improve his odds, especially near the end of a card deck that is not being reshuffled after every deal.

Book Detail

Thorp received his Ph.D. in mathematics from the University of California, Los Angeles in 1958, and worked at the Massachusetts Institute of Technology from 1959 to 1961. Thorp is the author of Beat the Dealer, which mathematically proved that the house advantage in blackjack could be overcome by card counting. He also developed and applied effective hedge fund techniques in the financial markets, and collaborated with Claude Shannon in creating the first wearable computer. Whatever you do, enjoy your life and the people who share it with you, and leave something good of yourself for the generations to follow.

For roulette, the Kelly strategy showed that it was worth trading a little expected gain for a large reduction in risk. An expert cheat or magician does this so well that even when you are told in advance and are watching close up, you can’t see.

One evening when, as I walked by the basement furnace room behind the co-op, I heard the sound of iron clanking. Curious, I ventured inside and found three muscular residents hoisting barbells. When I suggested that this seemed like a lot of work for who knew how much gain, they bet me a milkshake that if I worked out with them for one hour, three times a week, for a year, it would double my strength. When the year ended I had more than doubled what I could lift and gladly paid off the bet. This was the beginning of a lifelong interest in fitness and health. Cancel the membership at any time if not satisfied. For example, if I buy fire insurance for my house, my neighbor is a little safer.

Success on Wall Street was getting the most money. As Princeton Newport Partners closed I reflected on the proposition that what matters in life is how you spend your time.

If someone drives a polluting gasoline car and uses the atmosphere as a waste dump without paying any consequences, that’s a negative externality. Gun dealers make a lot of money, their clients go out and kill people, and society pays huge costs. He also shared his most recent list of what he does to promote healthy longevity, which we post in its lightly edited entirety below. “Founding professor of math donates personal, professional papers to UCI Libraries”. Thorp’s blackjack research is one of the very few examples where results from such research reached the public directly, completely bypassing the usual academic peer review process cycle. He has also stated that he considered the whole experiment an academic exercise. Thorp used the IBM 704 as a research tool in order to investigate the probabilities of winning while developing his blackjack game theory, which was based on the Kelly criterion, which he learned about from the 1956 paper by Kelly.

Paul Getty was the richest man in the world and manifestly not fulfilled, he said the happiest time of his life was when he was sixteen, riding waves off the beach in Malibu, California. I read stock market classics like Graham and Dodd’s Security Analysis, Edwards and Magee’s work on technical analysis, and scores of other books and periodicals ranging from fundamental to technical, theoretical to practical, and simple to abstruse.

  • something you hope to find in scientists but usually don’t.
  • I am here, as a trader and a practitioner of mathematical finance, to show its importance and put it in context for my community of real-world scientists – traders and risk-takers in general.
  • Yet he is humble — he might qualify as the only humble trader on planet Earth — so, unless the reader can reinterpret what’s between the lines, he or she won’t notice that Thorp’s contributions are vastly more momentous than he reveals.
  • My purpose here is not to explain or summarize the book; Thorp — not surprisingly — writes in a direct, clear, and engaging way.
  • For it is the straightforward character of his contributions and insights that made them both invisible in academia and useful for practitioners.
  • Ed Thorp is the first modern mathematician who successfully used quantitative methods for risk-taking — and most certainly the first mathematician who met financial success doing it.

It’s also nearly impossible to prove it ever happened. Cheating was so relentless during those days in Las Vegas that I spent as much time learning about the many ways it was being done as I did playing. Everywhere we went, we reached a point where we were cheated, barred from play, or the dealer reshuffled the cards after every hand. To protect myself from this happening with my work on blackjack, I settled on Proceedings of the National Academy of Sciences, as it was the quickest to publish of any journal I knew, taking as little as two or three months, and was also very prestigious. This required a member of the academy to approve and forward my work, so I sought out the only mathematics member of the academy at MIT, Claude Shannon. Claude was famous for the creation of information theory, which is crucial for modern computing, communications, and much more.

Investments presented a new type of uncertainty, but the theory of probability might help me make good https://forexarena.net/ choices. Things came together when I realized that there was a far greater casino than all of Nevada.

A Man For All Markets: From Las Vegas To Wall Street, How I Beat The Dealer And The Market (unabridged)

Life is like reading a novel or running a marathon. It’s not so much about reaching a goal but rather about the journey itself and the experiences along the way. As Benjamin Franklin famously said, “ Time is the stuff life is made of, ” and how you spend it makes all the difference. Best of all is the time I have spent with the people in my life that I care about — my wife, my family, my friends, and my associates. I invested money from book royalties and gambling winnings in stocks. But I was ignorant of the market as well as unlucky.

His remarkable success—and mathematically unassailable method—caused such an uproar that the casinos altered the rules of the game to thwart him and the legions he inspired. They barred him from their premises, instituted new rules, and put his life in jeopardy. News quickly spread throughout the gambling community, which was eager for new methods of winning, while Thorp became an instant celebrity among blackjack aficionados. Here, for the first time, Thorp tells the story of what he did, how he did it, his passions and motivations, and the curiosity that has always driven him to disregard conventional wisdom and devise game-changing solutions to seemingly insoluble problems. An intellectual thrill ride, replete with practical wisdom that can guide us all in uncertain financial waters, A Man for All Markets is an instant classic—a book that challenges its readers to think logically about a seemingly irrational world.

Starting as a university professor, I expected to spend my life teaching, doing research, and talking to smart like-minded people; but from childhood, I was intrigued by the power of abstract thinking to understand and direct the natural world. When I later saw how physics could predict roulette outcomes through the fog of chance, and mathematics could tip the odds in blackjack, I was drawn into a lifetime of adventure. It was my good fortune to share most of this journey with a remarkable companion. His objective was to outperform the market in the long run and so he judged himself largely on his performance relative to the market. In contrast, I didn’t judge the worth of various businesses. I enjoyed using mathematics to solve certain interesting puzzles, which I found first in the world of gambling, then in the world of investing.

When he said that there was no way to beat the casinos, I said with rash teenage hubris, encouraged by my idea about roulette, that someday I was going to do just that. Forty – six years later, when I stopped by our high school reunion for a couple of hours, the “ ins ” seemed the same as they had so long ago, only older and mellower. High school had been the apex of their lives. Many had married one another and lived locally ever since, whereas for me high school was a launching pad for life’s great adventure. For the rest of my life, I would meet Depression-era survivors who retained a compulsive, often irrational frugality and an economically inefficient tendency to hoard. Though we were poor, my parents valued books and managed to buy me one occasionally.

I wasn’t willing to accept these claims about blackjack. I decided to check for myself if the player could systematically win. We also agreed on the principles for raising them. We planned to give them all the education they wanted, teach them to think for themselves rather than simply accept received wisdom from experts and authority, and encourage them to choose their own calling in life. At this point, I had no interest in or experience with cards or gambling. However, one of the physics ideas I thought about briefly during this year was the analogy between a circling roulette ball and an orbiting planet.

Most of what I’ve learned from gambling also is true for investing. People mostly don’t understand risk, reward, and uncertainty. Their investment results could be much better if they did. Neither Jerry nor I believed the efficient market theory. I had overwhelming evidence of inefficiency from blackjack, from the history of Warren Buffett and friends, and from our daily success in Princeton Newport Partners . For bet sizing in favorable games, Shannon suggested I look at a 1956 paper by John Kelly. I adapted it as the guide for bets in blackjack and roulette, and later in other favorable games, sports betting, and the stock market.
