Reviews of A Man for All Markets Edward O Thorp

If you don’t have the habit, and you open your phone and tablet every time…you know what you’re doing. Reading a book is a process that I enjoy, it is one of my “keystone” habits. Others write bite-sized “buy this book” reviews which aren’t really reviews, only recommendations. Some people with popular blogs don’t even write book reviews, which they consider “below” them. That is why I’ll give you two book reviews one after another.

  • He ran the very successful hedge fund Princeton Newport Partners and Ridgeline Partners (18% YOY return in 25 years).
  • 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.
  • While Mr. Munger’s own comments from the meeting are worth reading, I’d suggest reading Thorp’s book first.
  • Mr. Thorp, in collaboration with Claude Shannon, developed the first wearable computer which was intended to provide the gambler with an edge in roulette.
  • The edge he found in games of chance led to valuable discoveries in finance, successful businesses, wealth, and fame.

Develop a Systematic Approach to Gambling and Investing

This paid off later because there weren’t any courses in how to beat blackjack, build a computer for roulette, or launch a market-neutral hedge fund.” Mark S. Rzepczynski, PhD, is CEO and Chief Investment Officer at AMPHI Research and Trading, a consulting firm to institutional investors and hedge funds on derivatives markets across all asset classes. Instead, in the short run, the stock market more closely resembles a casino with players who are interested in making quick gains. However, the volume of trading in the stock market makes it clear that the majority of activity has little to do with providing capital to business or allocating capital to its best and highest use. Of course, there is an element of truth in this sentiment since capital is indeed provided to business via the stock market. The book would provide even greater value for finance-oriented readers if it focused more on the “card counting” of finance and the identification of new trading opportunities.

The fact that Mr. Thorp dedicates this much space in his memoir to personal finance indicates that he believes lack of education in this area is a serious impediment to the well being of the public. The establishment at the time would not have believed that Bernie Madoff could be a fraud. Princeton Newport ran into trouble in late 1987 when the IRS and FBI raided the firm’s Princeton headquarters which housed the trading operations. This compared favorably to the S&P 500 annual return of 10.2 percent, but more importantly, it was accomplished with a small fraction of the volatility of the overall market. This resulted in a nearly twenty year track record in which the fund never posted a loss over a single calendar quarter. At the time, Mr. Thorp was managing about $400,000 and the accounts were grossing about 25 percent a year, with 20 percent of profits payable to the general partner.

The Wisdom of Finance

Professional investors can learn much from Thorp’s application of his gambling-based methods of solving problems, measuring probabilities, and formulating choices to stock and options trading. Ed Thorp is not well known among money managers, but he is held in awe by traders as a polymath, successful card counter, mathematician, finance specialist, and hedge fund manager. The race within financial market participants to be better and faster to gain an edge calculating fair values of instruments, ideally hedging off all risks becomes clear in the book. The last few chapters of the book delve into a number of personal finance topics that, while perhaps unexpected in a memoir, provide many good insights for both beginning and experienced investors. Today, what we call “hedge funds” are usually not market neutral funds of the type Mr. Thorp ran but are instead usually net long or net short, meaning that managers are taking a directional view of their holdings or the market as a whole. Early forays into investing in the silver market produced unsatisfactory results but Mr. Thorp’s self education continued, eventually reaching the subject of common stock warrants.

If he could maximize his understanding of the system, perhaps he could beat the market, just as he had beaten Vegas. You are forced to push and pull in opposite directions—to an extreme degree—at the same time. Both of these ideas are fantastic advice, but Thorp’s book made me realize that when you combine them there is a tension. But one of my other favorite ideas from Munger is that investors should stay within their circle of competence, and only bet big when they have a high conviction understanding. While Mr. Munger’s own comments from the meeting are worth reading, I’d suggest reading Thorp’s book first. Twenty years later, Ed Thorp’s autobiography, A Man for All Markets, was the only book Charlie Munger recommended at the 2017 meeting of the Daily Journal Corporation.

What impact did Beat the Dealer have on the gambling world according to A Man for All Markets?

As a result he launched a gambling renaissance. Unlike Mr. Buffett’s intention for his gift to the Gates Foundation, Mr. Thorp would like his gift to continue to provide funding for the chair in a man for all markets perpetuity. Warren Buffett reappears toward the end of the book as Mr. Thorp notes his use of Berkshire Hathaway shares to endow a chair in mathematics at U.C. Mr. Thorp concludes with a compelling account of the causes and aftermath of the financial crisis.

Also in Investment & Markets

Thorp’s journey from academia to gambling and investing was built on a solid mathematical foundation. Having brushed shoulders with casino mobsters and survived, he shared his secrets with the world, launching a gambling renaissance. And I would see it again and again in real life in both the gambling and the investment worlds.” Of course, I knew that just as the house can lose in the short run even though it has the advantage in a game, so a card counter can fall behind and this can last for hours or, sometimes, even days. This formula promises a life of hard work, but judgment based on evidence is the best road map for anyone practicing finance. Thorp makes it clear that achieving an edge is not easy and should not be attempted by most investors.

Lacking any background related to investing, Mr. Thorp spent the summer of 1964 educating himself, as he had on many other subjects earlier in life. Mr. Thorp, in collaboration with Claude Shannon, developed the first wearable computer which was intended to provide the gambler with an edge in roulette. However, the fact that many roulette wheels are not perfectly aligned and maintained implies that a gambler could gain an edge by waiting until the wheel and ball is in motion and betting based on minor flaws in the wheel. The nature of roulette implies a built-in advantage for the casino and casts doubt on the wisdom of participating at all since the expected value of a large number of bets will be negative for the gambler. Or course, casinos changed the rules when people like Thorp showed up, and many times he was declared non-grata. He ran the very successful hedge fund Princeton Newport Partners and Ridgeline Partners (18% YOY return in 25 years).

In retrospect, we can say that people who took cash rather than shares were crazy but virtually no one at the time thought that Berkshire would become Mr. Buffett’s investment vehicle for the next half century. Mr. Gerard had been a limited partner in the famous Buffett Partnership which was in the process of winding down at the time. Mr. Thorp’s ambition early in life was to excel in academia and he appears to have embraced the ethos of viewing scientific research as a public good. Stock market participants wouldn’t break your legs but would exploit a published strategy. One might ask why Mr. Thorp was willing to share his discoveries with the public, first with his technique for winning in blackjack and again with warrant mispricing.

“To get an edge picking stocks, focus on investments well within your knowledge and ability to evaluate, your ‘circle of competence.'” Thorp popularized the Kelly Criterion for optimal bet sizing in both gambling and investing. Thorp’s success in both gambling and investing came from identifying and exploiting inefficiencies. “Markets are basic to modern economics, and trading is a fundamental activity.” Thorp approached both gambling and investing with a rigorous analytical mindset. He applied probability theory and statistical analysis to develop groundbreaking strategies in blackjack and investing.

  • He believes that personal finance should be taught in elementary and secondary schools, noting that most people seem to not understand basic probability and statistics.

A Man for All Markets by E. Thorp Book Review

Do you stand when the dealer shows an upcard of 4, 5 or 6 ? Thorp thinks the ordinary player can still beat the game of blackjack. Good luck wasting your life away.

Book Review – A Man for All Markets, By Ed Thorp

Those who wish to make the attempt must choose between finding managers who can hopefully outperform the market after taking into consideration their fees or must do the work required to personally manage the account. The question of whether to attempt to beat the market or not is ultimately a personal decision. He believes that personal finance should be taught in elementary and secondary schools, noting that most people seem to not understand basic probability and statistics.

All the books longlisted for the Financial Times Business Book of the Year Award Join our investing challenges and compete for rewards while you learn! As Thorp reflects, “for the second time, the Ten-Count System had shown moderately heavy losses mixed with ‘lucky’ streaks of the most dazzling brilliance.

By applying the tools of physics, computer science and math to finance, Thorp created the world’s first “quant shop,” and a trading system that functioned profitably for decades with few drawdowns. In knowledge work fields (like investing), the variable you want to maximize is actionable understanding. Thorp’s contributions span academia, gambling, and finance, establishing him as a multifaceted innovator in applied mathematics and probability theory. He pioneered modern hedge fund techniques and collaborated with Claude Shannon to create the first wearable computer in 1961. However, some find the book self-aggrandizing and criticize the later chapters for basic financial information.

The Pitbull of Wall Street

Mr. Thorp retained his professorship for several years before finally dedicating all of his time toward investing in the early 1980s. Although Mr. Buffett’s style of investing extended far beyond Mr. Thorp’s activities, he apparently had a positive overall assessment since Mr. Gerard ended up investing additional funds with Mr. Thorp. The casinos would become aware of card counting and take countermeasures to deal with it, some of which proved to be physically dangerous. By purchasing the relatively underpriced security and shorting the overpriced security, one can exploit the market’s mistake without necessarily expressing an opinion on the merits of investing or shorting the underlying business. The value of a warrant on a common stock is derived based the difference between the current stock price and the exercise price of the warrant as well as the amount of time before the warrant expires.

In the idealistic view of economics, the stock market is a venue for providers of capital to invest in promising businesses that have the ability to generate attractive returns on capital. While the methods for gaining an edge in baccarat were similar to those used in blackjack and could be pursued through human intellect alone, the challenge facing the roulette player was far more complicated. Driven by an innate sense of curiosity and powered by raw intellect, combined with some help from early computer technology, Ed Thorp demonstrated that players could gain an edge in blackjack through straight forward card counting methods.

Conventional wisdom in the 1950s held that it is impossible for players to gain a consistent edge in games such as blackjack, baccarat and roulette. Although I’m in finance, I dab in games of luck, so I was very interested in the blackjack and roulette technique Thorp develop in the ’60s. Thorp gained fame for his 1962 book “Beat the Dealer,” which mathematically proved that card counting could overcome the house advantage in blackjack. A Man for All Markets receives praise for its fascinating insights into Thorp’s life, from beating casinos to pioneering quantitative finance.

Mr. Thorp came up with the idea of developing mathematical models to determine whether warrants are mispriced relative to the price of the common stock. He included Graham and Dodd’s Security Analysis in his reading but also went further into scores of other books including the study of technical analysis. It was the fourth night at the tables and the pit boss and casino management had taken note of the lead player’s wins and were not happy. The team of six, three men and three women, pretended not to know each other and made their way to the baccarat tables at the Dunes casino in Las Vegas. You’re being fucked ever time and time again…I don’t mean it properly. Further, you must consider them one at a time, and having once rejected someone, you cannot reconsider.
