The Man Who Solved the Market Book Summary
In the financial markets, Jim Simons looks for patterns. In his eyes they are beautiful, mysterious forms, like shoals of fish or nebulae visible in the night sky.
He knows that mathematics is at the heart of these patterns, as with everything else in the universe. With mathematics, he is able to predict these patterns. This allows him to make money – and lots of it.
In modern history, Jim Simons has been the most successful investor. His hedge fund firm, Renaissance Technologies, is hailed as a global standard-bearer in the business world – financial analysts strive to understand its secretive, ground-breaking methods.
The mathematician, code-breaker, and philanthropist is much more than a Wall Street money man: he’s had a career that should span several lifetimes. These insights provide a glimpse into his extraordinary life.
Lesson 1: Jim Simons became obsessed with math at a very young age
As soon as he understood what numbers were, Jim Simons became fascinated with them.
James Simons was born to a middle-class American Jewish family in Brookline, Massachusetts, in 1938.
Almost from the very beginning, he showed an interest in numbers like many other people with unusual abilities. At the age of three he began solving complex problems. His parents found him dividing numbers in twos, starting with 1024 and going down from there. It was quite a feat for a toddler.
On another occasion, Jim was baffled when his father had to stop for gas while out for a family drive. Jim was baffled by this, as the tank would never run out. According to him, if they used up half of what was in the tank, there would be another half left. Once they used half of that other half, there would be another, smaller half left to use.
A four-year-old had started to work on a classic mathematical problem, one of those Zeno addressed in his group of paradoxes. No matter how small the remaining distance is, if you have to travel half of it before reaching your destination, how can you ever reach it?
As a young man, Jim had been encouraged to go into medicine by the family doctor. However, Jim had other plans.
After enrolling at MIT, he studied mathematics for a bachelor’s degree. A summer break helped him to nail the more complicated theorems after struggling initially and failing a few tests. His performance improved after that.
He liked how complex formulae were often linked to other formulae across mathematics, suggesting a universal system. A code of some sort could possibly explain the world’s mysteries, he wondered. While contemplating an equation, he was often spotted lying on his back, closed eyes.
He once saw two of his professors, Warren Ambrose and Isadore Singer, deep in conversation in a local café at midnight. He decided then that this is the kind of life he wanted: cigarettes, coffee, and mathematics at all hours.
Lesson 2: Simons entered academia soon after completing his studies, but left to crack Soviet codes for an intelligence agency
Simons sought a lectureship after achieving academic success at MIT and Berkeley.
He earned his PhD in two years at Berkeley. During this time, he studied curved multidimensional spaces in geometry. Its brilliance was enough to secure him a teaching position at Harvard University.
There was a popular professor there with an informal, enthusiastic style that matched his casual clothing (he often wore sandals without socks). The way he taught was as fresh as a beginner’s. In some cases, in particular, he admitted that he knew little more about algebra than his students.
Eventually, he became tired of teaching. He was terminally bored as his life had taken on a predictable pattern of lectures and polite academic socializing. He craved a new challenge.
In 1964, Simons left Harvard and joined an intelligence agency that fought the Cold War. An elite research organization hired mathematicians to crack Soviet codes, the Institute for Defence Analysis.
The IDA was struggling at the time. It had been over a decade since they actually cracked Soviet codes. As a result of this lack of success, they hired people without code-breaking experience, such as Simons, to provide pure brainpower. There were a lot of people in that place like Simons: lovers of obscure theorems and long arguments about math.
Simons learned how to construct mathematical models to interpret meaning from seemingly meaningless data at the IDA, whose motto was “bad ideas are good, good ideas are terrific, and no ideas are bad.” This is where Simons developed an ultrafast code-breaking algorithm.
In the aftermath of Simons’ innovation, intelligence experts in Washington found that a Soviet coded message had been sent with an incorrect setting.
As a result of this glitch, Simons and his colleagues exploited the enemy’s internal messaging system using their code-breaking model. Simons became a sort of cult hero at IDA and in the code-breaking community as a whole as a result.
Jim’s restless mind couldn’t settle for even this success. To accomplish more mathematical challenges, he longed to solve more cryptic codes.
Lesson 3: Simons achieved tremendous success in geometry and developed a new stock-trading system.
IDA employees had plenty of free time while trying to crack codes. Simons spent his time wisely – researching and pondering the world of global finance.
As he was still at the IDA, he began to see the benefits of his research into geometry. Rather than focusing on practical applications, he focused on theoretical questions. He spent days in abstract reflection on this piece of math, which one might call pure math.
In his research, he examined the question of surface area, a highly complex topic called “minimal varieties”.
In one classical example, a soap film is stretched across a wire frame dipped in soapy solution, forming a surface. In comparison with any other type of surface stretched between the same wire frame, the soap film has the smallest surface area.
Regardless of how complicated or twisted a wire frame might be, every point on such a smooth surface will appear the same.
He was curious if the same would apply to minimal surfaces in higher dimensions, rather than just two-dimensional wire frames.
“Minimal Varieties in Riemannian Manifolds,” published in 1968, helped establish him as one of the world’s foremost geometers.
Simons still couldn’t keep himself occupied. He started looking for ways to apply his aptitude for numbers to measuring the stock market in order to earn more money.
Simons began to look at the market the same way he did math: as an abstract intellectual system rather than the tried-and-tested investment methods that took into account earnings and corporate news.
By analyzing “moves” within stocks, rather than looking at the outside environment, he developed a model.
According to him, the markets have eight fundamental states, such as “high variance,” when stocks move erratically, or “good,” when stocks rise generally. It was a system that was not interested in “why” a market entered certain states, but simply observed the different states and allowed investors to place bets accordingly.
In his time, he was something of a trailblazer, even if his work was crude. Predictive theory eventually resembled his approach across multiple fields.
Lesson 4: Simons founded Monemetrics after a second stint in academia
In 1968, Jim was fired from his code-breaking position at IDA for revealing his opposition to the Vietnam War to his colleagues.
As a result, he looked for another job and quickly returned to academia. The math department at Stony Brook University, New York, appointed him chairman. He still wanted to explore the world beyond the lecture hall.
At the age of forty, he left academic life and founded Monemetrics, a hedge fund management firm. His goal was to identify markets’ hidden patterns.
Additionally, he had to admit to himself that he wanted to be very rich. He was drawn to money in contrast to most of his colleagues.
The first thing he did was invite an old friend from IDA, Leonard Baum, to become his partner. It was Baum who co-authored the Baum-Welch algorithm, which became an integral part of monemetrics.
Based on a series of events, it predicted outcomes without knowing the underlying parameters or variables. A hidden Markov chain is a series of events that cannot be predicted.
The algorithm of Baum-Welch works by making educated guesses – analyzing a chain of events and estimating probabilities. It could, for example, estimate what would happen next simply by analyzing patterns in a play without knowing baseball rules. Google’s search engine and speech-recognition technology will benefit greatly from it in the future.
The model developed by Simons and Baum would be handy for monitoring the movements of the markets. As it was 1979, before digitized trading, they hung charts and graphs on the walls of their office in a Long Island strip mall to measure data.
They began to make a great deal of money only trading currencies at first. In one memorable episode, Baum experienced an epiphany while relaxing on the beach. He realized that they needed to buy plenty of British pounds.
The new British prime minister, Margaret Thatcher, was keeping the pound at an unnaturally low rate. Baum predicted it would rise very soon, so he hurried from the beach straight to Simons’ Long Island office and harangued him to buy while the market was still low. His prediction came true when the pound soared rapidly.
Tens of millions of dollars poured into Monemetric’s fund, like the sea flooding a hollow.
Lesson 5: Simons named his Monemetrics fund after a character in a Joseph Conrad novel
The first time Simons ventured into the world of finance was through monemetrics. Having gathered a team of mathematicians around him and Baum, including old college friends, he began to work on the project.
After he had persuaded others to team up with him in this endeavor, he established a hedge fund where they would manage their investments.
A nickname was given to it: Nimroy, which was a play on Lord Jim and the Royal Bank of Bermuda, which handled money transfers for tax purposes (namely, to avoid paying taxes).
The name was an amalgamation of high finance and a character who was struggling with the ideals of honor and morality. The young seaman in Lord Jim abandons a sinking ship, leaving its passengers at the mercy of the waves. The rest of the book chronicles the story of a disgraced seaman trying to come to terms with his past and conscience.
Greg Hullender, a recent hire at Monemetrics, said Simons was similar to the seaman in Conrad’s novel. While Jim had abandoned his more “noble” career as an academic in pursuit of immense riches, the seaman’s moral struggle resonated with him.
Jim began to think he’d done something similar by getting into finance, like abandoning a ship, which was a terrible black mark on a seaman’s honor.
In the early stages of Monemetrics, troubled waters would be experienced just as they were in Conrad’s novel. Though they bought low, they did not sell high. In one instance, they bought into gold, which had soared to $865 per ounce.
Monemetrics failed to sell fast enough, causing gold to crash shortly afterwards to $500 an ounce. These losses became more frequent, reaching a point where the fund was losing millions of dollars every day.
One day, Greg Hullender found Simons lying on the couch of his office. Hullender asked Jim if he was OK. Lying on the bed, Jim began to doubt himself, wondering if he didn’t know what he was doing.
He brought up Lord Jim again, commenting that the character has a high opinion of himself but has failed miserably. Though he had a good death, he said, darkly.
Lesson 6: Simons brought computers into the world of investment with great success
As it turned out, Monemetrics’ losses would soon be reversed. Nevertheless, they had to first develop a better system for reading market movements.
Other investors were using old-fashioned intuition as well as economic news for their predictions, but Simons decided to use computers – a technology that wasn’t widely available in the 1980s. Monemetrics was renamed Renaissance Technologies as he looked ahead to a bold new world of investing.
The first thing he did was to collect large quantities of historical data and feed it directly into his computer. From the World Bank, he purchased stacks of books, magnetic tape from commodity exchanges, and records of currency prices going back before World War II.
By doing this, he was able to analyze previous market movements for patterns that might be applicable to the present.
The present, however, was becoming more volatile. Although there were broad resemblances, it was difficult to extrapolate patterns that were relevant to the present based on historical data. It was therefore necessary to monitor the present as rapidly as possible.
In order to accomplish this, they invested in lots of expensive computers, enormous amounts of storage, and high-speed connections to the market. This gave investors access to live market prices that no one else had.
These floods of data were combined with Baum’s predictive mathematics, improved by another member of Simons’ team, prize-winning algebraist James Ax.
Ax’s tweaks improved Baum’s return by making Baum’s method better suited to predicting “dynamic” series, such as the volatile markets of the 1980s.
Furthermore, by the time they refined their model, better computers had become available, enabling them to monitor new data.
In a nod to the mathematics successes they’d both had in the past, Simons and Ax dubbed the Renaissance hedge fund “Medallion.” As a result of their combined expertise, the Medallion fund led Renaissance to its greatest profitability.
Eventually, it gained fame for having the best record in investing history, returning 66 percent in annual returns and earning over $100 billion in trading profits. Though they had not “solved” the markets, they had found a way to trace their slightest tremors and shifts.
Lesson 7: Simons’ career would bring him into contact with a brilliant man who would court great controversy
Renaissance searched for more brainpower as it expanded its investment activities. An IBM employee named Robert Mercer was among these new recruits. He laid the foundation for advances in speech-recognition technology while at IBM.
He was the exact type of person Renaissance was looking for: a brilliant coder. During the 1960s and 1970s, Mercer spent much of his childhood and adolescence on a computer keyboard. When he was a teen, he’d met Neil Armstrong at a West Virginia science camp, giving a talk to budding computer scientists.
Mercer began working in a weapons laboratory as a computer programmer after graduating from college. He then made some significant improvements to the speed of lab computers and his bosses, who were uninterested in his work, told him not to bother them.
According to Mercer, they were more concerned about checking boxes than using government research funds. Mercer became an opponent of government. Eventually, he would come to the conclusion that individuals need to be self-sufficient and avoid state assistance.
He helped Renaissance identify flaws and glitches in the system, contributing to the firm’s success throughout the 1990s. He was best known, however, for his political affiliations.
His laconic sense of humor and quiet manner did not immediately suggest that he had strong ideological beliefs. However, he did, and these led him to fund right-wing political movements and publications, including Breitbart and the campaign to elect Donald Trump as US president.
The situation contrasted with Jim Simons, who donated millions to Democrat candidates over the years. In the midst of the cut and thrust of finance, these differences didn’t seem to matter so much.
Mercer, who was a co-CEO at Renaissance then, was forced out of his position when he financed Trump’s presidential campaign in 2016. It is believed that Jim Simons made the final call.
Mercer and Simons are idiosyncratic geniuses in math and computing, respectively. As they quietly tapped away at their keyboards, they would have a profound impact on the world in their own ways, disruptions for better and worse.
Lesson 8: Jim Simons’ CV is an astonishing one at the end of the day
Medici were a powerful banker family who influenced the course of politics, art, and royal power in medieval Italy. There’s no denying that Jim Simons is the modern equivalent of one of those members of the dynasty. Counting up all of his accomplishments, he is truly awe-inspiring.
First of all, he is the most successful trader in the history of modern finance.
His Renaissance profits are unmatched by anyone in the investment world. All those trading legends, such as Warren Buffett, George Soros, Peter Lynch, Steve Cohen, and Ray Dalio, failed. It has been calculated that Medallion fund profits total around £100 billion. Still,
Renaissance has managed to earn $7 billion in trading profits each year in recent years. That’s more than the annual revenue of major brands such as Levi Strauss, Hyatt Hotels, and Hasbro.
Renaissance’s pioneering trading methods influenced fields far beyond finance.
They have been adopted by almost every industry. No professional sports team in the world does not use the mass statistic crunching that Renaissance and Monemetrics did.
Another example is automating tasks – the military is increasingly relying on robots, and health professionals are using computers to diagnose illnesses.
Algorithms are used in nearly every field where forecasting is needed.
Simons’ influence extends beyond industry. He later became a great benefactor after having made lots of money.
Simons has subsidized organizations and individuals around the world in the same manner as the Medicis, patrons of great Renaissance painters and scholars.
As examples, he founded the Simons Foundation for education and health, the Math for America initiative, aided the development of Nepalese healthcare, and generously donated to Stony Brook University.
Simons is notoriously hard to reach today. Former and current Renaissance employees are sworn to secrecy about Renaissance’s trading secrets.
Jim Simons has become one of the most powerful and enigmatic people in the world, having spent his childhood dreaming of numbers.
Jim Simons began his career as a gifted mathematician before tackling Soviet codes.
He then revolutionized the world of investing with Renaissance Technologies. He revolutionized global finance by combining mass data, algorithms, and computing.
He has amassed considerable wealth and is now a powerful benefactor to an array of progressive causes and organizations.
