The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution
by Gregory Zuckerman
Published 5 Nov 2019

Soon, it was managing several hundred million dollars, trading an array of equity-related investments, and boasting over one hundred employees. Jim Simons didn’t have a clear understanding of the kind of progress Shaw and a few others were making. He did know, if he was going to build something special to catch up with those who had a jump on him, he’d need some help. Simons called Sussman, the financier who had given David Shaw the support he needed to start his own hedge fund, hoping for a similar boost. CHAPTER EIGHT Jim Simons’s pulse quickened as he approached Sixth Avenue. It was a sultry summer afternoon, but Simons wore a jacket and tie, hoping to impress.

The Quants
by Scott Patterson
Published 2 Feb 2010

Mere days before the crash, Asness’s hedge fund was on the verge of filing the final papers for an initial public offering. Boaz Weinstein, chess “life master,” card counter, and powerful derivatives trader at Deutsche Bank, who built his internal hedge fund, Saba (Hebrew for “wise grandfather”), into one of the most powerful credit-trading funds on the planet, juggling $30 billion worth of positions. Jim Simons, the reclusive, highly secretive billionaire manager of Renaissance Technologies, the most successful hedge fund in history, whose mysterious investment techniques are driven by scientists poached from the fields of cryptoanalysis and computerized speech recognition. Ed Thorp, godfather of the quants.

More important to the gathering crowd, Gowen was one of the most successful female poker players in the country. Muller, tan, fit, and at forty-two looking a decade younger than his age, a wiry Pat Boone in his prime, radiated the relaxed cool of a man accustomed to victory. He waved across the room to Jim Simons, billionaire math genius and founder of the most successful hedge fund on the planet, Renaissance Technologies. Simons, a balding, white-bearded wizard of quantitative investing, winked back as he continued chatting with the circle of admirers hovering around him. The previous year, Simons had pocketed $1.5 billion in hedge fund fees, at the time the biggest one-year paycheck ever earned by a hedge fund manager.

Pension funds across America, burned by the dot-com collapse in 2000, rushed into hedge funds, the favored vehicle of the quants, entrusting their members’ retirement savings to this group of secretive and opaque investors. Cliff Asness’s hedge fund, AQR, had started with $1 billion in 1998. By mid-2007, its assets under management neared $40 billion. Citadel’s kitty topped $20 billion. In 2005, Jim Simons announced that Renaissance would launch a fund that could juggle a record $100 billion in assets. Boaz Weinstein, just thirty-three, was wielding roughly $30 billion worth of positions for Deutsche Bank. The growth had come rapid-fire. In 1990, hedge funds held $39 billion in assets. By 2000, the amount had leapt to $490 billion, and by 2007 it had exploded to $2 trillion.

The Physics of Wall Street: A Brief History of Predicting the Unpredictable
by James Owen Weatherall
Published 2 Jan 2013

Acknowledgments Notes References Introduction: Of Quants and Other Demons WARREN BUFFETT ISN’T the best money manager in the world. Neither is George Soros or Bill Gross. The world’s best money manager is a man you’ve probably never heard of — unless you’re a physicist, in which case you’d know his name immediately. Jim Simons is co-inventor of a brilliant piece of mathematics called the Chern-Simons 3-form, one of the most important parts of string theory. It’s abstract, even abstruse, stuff — some say too abstract and speculative — but it has turned Simons into a living legend. He’s the kind of scientist whose name is uttered in hushed tones in the physics departments of Harvard and Princeton.

The quant funds limped their way to the end of the year, hit again in November and December by ghosts of the August disaster. Some, but not all, managed to recover their losses by the end of the year. On average, hedge funds returned about 10% in 2007 — less than many other, apparently less sophisticated investments. Jim Simons’s Medallion Fund, on the other hand, returned 73.7%. Still, even Medallion had felt the August heat. As 2008 dawned, the quants hoped the worst was behind them. It wasn’t. I began thinking about this book during the fall of 2008. In the year since the quant crisis, the U.S. economy had entered a death spiral, with century-old investment banks like Bear Stearns and Lehman Brothers imploding as markets collapsed.

In addition to Bear Stearns and Lehman Brothers, the insurance giant AIG as well as dozens of hedge funds and hundreds of banks either shut down or teetered at the precipice, including quant fund behemoths worth tens of billions of dollars like Citadel Investment Group. Even the traditionalists suffered: Berkshire Hathaway faced its largest loss ever, of about 10% book value per share — while the shares themselves halved in value. But not everyone was a loser for the year. Meanwhile, Jim Simons’s Medallion Fund earned 80%, even as the financial industry collapsed around him. The physicists must be doing something right. 1 Primordial Seeds LA FIN DE SIÈCLE, LA BELLE EPOQUE. Paris was abuzz with progress. In the west, Gustave Eiffel’s new tower — still considered a controversial eyesore by Parisians living in its shadow — shot up over the site of the 1889 World’s Fair.

More Money Than God: Hedge Funds and the Making of a New Elite
by Sebastian Mallaby
Published 9 Jun 2010

(Clifford Asness, “The August of Our Discontent: Questions and Answers about the Crash and Subsequent Rebound of Quantitative Stock Selection Strategies,” working paper, September 21, 2007.) In an e-mail to investors, Jim Simons wrote, “While we believe we have an excellent set of predictive signals, some of these are undoubtedly shared by a number of long/short hedge funds.” (Jim Simons, e-mail to Renaissance Technologies investors, August 9, 2007.) 32. Satya Pradhuman, director of research at Cirrus Research, identified 148 companies with market capitalizations between $2 billion and $10 billion and 473 companies with market capitalizations between $250 million and $2 billion in which large quant funds had ownership stakes exceeding 5 percent.

Hedge funds are the vehicles for loners and contrarians, for individualists whose ambitions are too big to fit into established financial institutions. Cliff Asness is a case in point. He had been a rising star at Goldman Sachs, but he opted for the freedom and rewards of running his own shop; a man who collects plastic superheroes is not going to remain a salaried antihero for long, at least not if he can help it. Jim Simons of Renaissance Technologies, the mathematician who emerged in the 2000s as the highest earner in the industry, would not have lasted at a mainstream bank: He took orders from nobody, seldom wore socks, and got fired from the Pentagon’s code-cracking center after denouncing his bosses’ Vietnam policy.

By buying value stocks and shorting growth stocks, Cliff Asness was doing his part to reduce the unhealthy bias against solid, workhorse firms. By buying Ford’s stock when it dipped illogically after a large-block sale, Michael Steinhardt was ensuring that the grandma who owned a piece of Ford could always count on getting a fair price for it. By computerizing Steinhardt’s art, statistical arbitrageurs such as Jim Simons and David Shaw were taking his mission to the next level. The more markets could be rendered efficient, the more capital would flow to its most productive uses. The less prices got out of line, the less risk there would presumably be of financial bubbles—and so of sharp, destabilizing corrections.

Trend Commandments: Trading for Exceptional Returns
by Michael W. Covel
Published 14 Jun 2011

As we draw out a ball it becomes part of the track record, and we put it back in the bag, but there is no guarantee that the balls will come out in the same order in the future.1 Science “Do you have a clear sense of probabilities and payoffs?” Did you answer “no?” If so, you need to figure it out, and fast. For example, trader Jim Simons (arguably a closeted trend trader—he does not identify as one), worth about $8.5 billion, has said that the advantage scientists brought to the trading table was not their computing or math skills, but their ability to think scientifically. That means the scientific method is in play: 1. Define the question/theory. 2.

Dark Pools: The Rise of the Machine Traders and the Rigging of the U.S. Stock Market
by Scott Patterson
Published 11 Jun 2012

ANDRESEN was in the middle of his well-rehearsed pitch, ticking off all the benefits that Island brought investors who thrived on blinding speed and nosebleed volumes. The instant execution. The gobs of streaming data. The dirt-cheap fees. And if anyone was in the market for speed, data, and low fees, it was the hedge fund he was pitching to: Renaissance Technologies. But the reclusive, white-bearded chieftain of Renaissance, Jim Simons, didn’t seem to be listening. In fact, it seemed as if Simons had dozed off in the middle of Andresen’s presentation in a conference room at Island’s 50 Broad headquarters, his Merit cigarette burning to a cinder in an ashtray before him. Was Simons actually snoring? Disconcerted, Andresen muddled on, addressing his speech to the other Renaissance executives in the room, Peter Brown and Bob Mercer, the former IBM AI experts who’d turned Renaissance into an invincible trading machine.

Brown, a wiry man in his early fifties with masses of dark wavy hair, had, like Peterffy, seen his share of market panics—the Asian flu of the late 1990s, the dot-com implosion, the credit crisis of 2008. Along with Bob Mercer, his colleague for decades, dating back to their time developing AI language translation systems for IBM in the 1980s, he’d taken the reins at Renaissance in early 2009 from its founder, Jim Simons. It was one of the most plum jobs in all of finance. Brown had never seen a market move so quickly. The speed of the decline was breathtaking. He wasn’t overly worried. Because of Renaissance’s AI trading systems, alert to the mere whisper of trouble in its strategies, the plunge wasn’t likely to impact the firm’s $10 billion or so worth of holdings in its flagship hedge fund, Medallion.

The feedback loop was broken. The machines regrouped. Instead of selling, they started buying. The market recovered—and then it surged. BACK at Renaissance, Peter Brown was stunned as he watched the market whiplash. Just as quickly as it had crashed, it began rebounding. Brown had called Renaissance founder Jim Simons to notify him that the market had plunged 9 percent. But he couldn’t explain what had happened. Then, shortly before 2:46 P.M., the rebound kicked in. “Wait,” Brown told Simons as the market ticked up suddenly. “It’s down eight percent. Now it’s down seven percent.” Exchange executives raced to contain the damage.

Short-term trading, by definition, is not less risky, as evidenced by the catastrophic blowout of Victor Niederhoffer and Long Term Capital Management (LTCM). Do some short-term traders excel? Yes. However, think about the likes of whom you might be competing with when you are trading short term. Professional short-term traders, such as Jim Simons, have hundreds of staffers working as a team 24/7. They are playing for keeps, looking to eat your lunch in the zero-sum world. You don’t stand a chance. Unfortunately, the flaws in day trading are often invisible to those who must know better. Sumner Redstone, CEO of Viacom, was interviewed recently and talked of constantly watching Viacom’s stock price, hour after hour, day after day.

Madoff Talks: Uncovering the Untold Story Behind the Most Notorious Ponzi Scheme in History
by Jim Campbell
Published 26 Apr 2021

As to the professional investors who he claimed legitimized his fund through their investments, he said: “I handled the foundation account in this SSC strategy for years for Jim Simons, the highly regarded and hugely successful Head of Renaissance Technologies, and the QUANT hedge fund. Also, Simons executed a huge amount of his firm’s trading through my market-making side. Like all my clients he received daily confirmations of every trade we did for his account in the SSC strategy and he never thought it looked too good to be true. This myth was completely generated by the SIPC Trustee. Do you believe I would have been able to FOOL so many pros for 16 years?”7 I looked into whether Jim Simons, who had generated the best hedge fund returns for decades, averaging annual returns of 66 percent gross and 39 percent net of fees, was really a Madoff investor.

—Bethany Mclean, New York Times bestselling author of The Smartest Guys in the Room: The Amazing Rise and Scandalous Fall of Enron Campbell sheds new light on perhaps the biggest and most improbable scandal in financial history, providing valuable and fresh insights into Madoff’s enterprise and the man himself. —Gregory Zuckerman, Special Writer at the Wall Street Journal and New York Times bestselling author of The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution Madoff Talks is a gripping, fast-paced insider’s account of the story behind the story of the biggest Ponzi scheme in American history. I never understood how or why Bernie Madoff created a culture that sucked in so many unquestioning participants for so long. But thanks to Campbell’s relentless reporting, we hear not just from Bernie Madoff himself but from his wife, Ruth, his late son Andrew, and many others who worked for him.

SEC bureaucratic winds, driven by a big mutual funds pricing scandal generating media exposure, caused the exam team to shift focus without resolving the Madoff investigation. The final report accepted Madoff’s verbal dodges. Failure was baked into the examination before it was belatedly launched and prematurely curtailed. 4. Internal Emails at the Hedge Fund of the Greatest Investor Ever (April 2004) Jim Simons of Renaissance Technologies was invested indirectly in Madoff via a feeder fund. His hedge fund was full of brilliant mathematicians, with an extraordinary track record averaging annual net returns of 39 percent. Madoff continually cited to me Simons’s investments in his fund as proof his returns must be real.

Radical Uncertainty: Decision-Making for an Unknowable Future
by Mervyn King and John Kay
Published 5 Mar 2020

Securities traders, unlike poker players, are not operating in a small and stationary world, and there is no equivalent basis for calculating probabilities, but opportunities for making similar decisions arise often, and the outcomes are clear. So it is possible to learn from long runs of successful results; hedge fund manager Jim Simons’ trading algorithms have been – overall – very profitable. We may perhaps learn even more from long runs of unsuccessful results, although few traders are given the opportunity to establish these. But the calculation of ‘alpha’, a widely employed measure of fund manager ‘skill’, generally assumes, without justification, that investment returns are drawings from a stationary probability distribution.

One is that the models used by regulators and financial institutions, directly derived from academic research in finance, not only failed to prevent the 2007–08 crisis but actively contributed to it. Another is to look at the achievements of the most successful investors of the era – Warren Buffett, George Soros and Jim Simons. Each has built fortunes of tens of billions of dollars. They are representative of three very different styles of investing. Buffett’s investment company, Berkshire Hathaway, owns large, often controlling and in many cases 100% interests in a wide variety of businesses. Buffett’s philosophy is to buy into businesses with strong competitive advantages, install outstanding managers – or in many cases find them within a company – and grant them almost total discretion.

But we do know that diversification reduces the risk that the reference narrative – the reliable emergency fund, the security of retirement, the continued growth of the college endowment – might not be realised. The efficient market hypothesis, taken literally, implies that the investment success of George Soros, Warren Buffett and Jim Simons is impossible. Frank Knight, who recognised that radical uncertainty generates profit opportunities, has been vindicated by the extraordinary riches accumulated by these men. And the efficient market hypothesis is shown to be illuminating – an indispensable model – without being true. Buffett, history’s most successful investor, was well aware of this.

Quantitative Trading: How to Build Your Own Algorithmic Trading Business

This can be shown to be true on many fronts. Many legendary quantitative hedge fund managers such as Dr. Edward Thorp of the former Princeton-Newport Partners (Poundstone, 2005) and Dr. Jim Simons of Renaissance Technologies Corp. (Lux, 2000) started their careers trading their own money. They did not begin as portfolio managers for investment banks and hedge funds before starting their own fund management business. Of course, there are also plenty of counterexamples, but clearly this is a possible route to riches as well as intellectual accomplishment, and for someone with an entrepreneurial bent, a preferred route.

Other People's Money: Masters of the Universe or Servants of the People?
by John Kay
Published 2 Sep 2015

The outcome was profitable for hedge fund promoters although not, in general, for their investors.11 Groups of traders with a successful record in investment banks established their own operations. Some hedge fund managers made extraordinary sums. George Soros has reported wealth of $26.5 billion: Jim Simons, a former mathematics professor, $15.5 billion.12 The reward for traders within banks increased, substantially if not commensurately, as these companies tried to keep hold of what they called ‘the talent’. The rise of the trader and the development of a trading culture cannot be dissociated from the political climate of the times: the power of a market fundamentalist ideology, the election of Thatcher and Reagan, the collapse of the Soviet Union and the discrediting of central planning as an economic system.

Some thoughtful commentators believed that the financial institutions of the future would be narrow specialists.13 And indeed most functions of banks are now also performed by specialist institutions, such as credit card companies and mortgage banks. Supermarkets diversified into simple financial services, such as deposit accounts. Private equity houses (venture capital firms) specialise in the provision of finance for business. Specialist hedge funds – tightly run speculative trading ventures such as those of George Soros and Jim Simons – attracted funds in the years after 2000. But, apparently paradoxically, the trend to specialisation was accompanied by a trend to diversification. Regulation Q, which restricted interest rates, was successively relaxed and finally scrapped in 1986. The American finance sector, which had been publicly humiliated in 1933, became a more and more powerful lobby.

In the end, the LTCM trades were settled profitably by the investment banks which had taken them over: a telling illustration of Keynes’s (possibly apocryphal) dictum that ‘markets can remain irrational for longer than you can stay solvent’.4 More recently, the mathematical analysis of trading patterns has enabled some algorithmic traders to make returns from minute movements in the prices of securities. The most persistently successful of these quantitative-oriented funds are the Renaissance Technologies funds of Jim Simons, which have over more than two decades earned extraordinary returns for investors while charging equally extraordinary levels of fee. Simons was a distinguished mathematician before taking to finance. The early and successful practitioners of this quantitative style could use sophisticated methods to identify recurrent patterns in data, and arbitrage anomalies in the manner of LTCM.

Madoff: The Final Word
by Richard Behar
Published 9 Jul 2024

At other times, he was vague, simply mentioning the names of firms that his top investors supposedly worked for. “Do you think all of these professionals on Wall Street,” he said by phone in 2012, “like Jim Simons, [David] Komansky, all these other people—partners of Goldman, and Merrill, and Morgan Stanley—would invest with me if they didn’t believe in my strategy? They didn’t see anything wrong. Doesn’t mean there wasn’t something wrong [laughs].” It turns out, however, that it was only a charitable foundation of Jim Simons’s that had a small account with Bernie. Once Simons—considered one of the greatest hedge fund traders alive—conducted an analysis of Madoff, he pulled out the funds.

Whenever Bernie talked about his (fake) split-strike strategy, he’d always say that he never actually did the trades, but that they would have made sense if he had executed them. “And you can’t say that people should have known, because the strategy made sense,” he once said, “and a perfect example of why it made sense are people like Jim Simons and David Komansky.” This baffled Komansky. “How the hell he got my name is beyond me because I was three levels away from investing directly with him,” he said. “I never invested with Bernie.” He laughed. “Never.” Komansky said he invested in a private partnership that invested in a Madoff feeder fund.

Adaptive Markets: Financial Evolution at the Speed of Thought
by Andrew W. Lo
Published 3 Apr 2017

At its theoretical and frictionless limit, the Adaptive Markets Hypothesis includes the Efficient Markets Hypothesis as a special case. In practice, however, this limit is rarely attained, and if it is, it usually doesn’t last very long. Today’s financial markets are still distant from a theoretical end-state of perfectly efficient markets. Investors as different as Warren Buffett and Jim Simons consistently out-earn the index funds favored by the Efficient Markets Hypothesis, despite their very different investment strategies. Unlike the Efficient Markets Hypothesis, the Adaptive Markets Hypothesis makes no claim that markets will always become more efficient over time. Instead, it predicts more complicated market dynamics.

THE RANDOM WALK REVISITED The adaptive implications for index funds, volatility management, and the risk/reward trade-off are all well and good, but what does the Adaptive Markets Hypothesis have to say about the financial question people seem to care about the most: “Can I beat the market?” And if the answer is yes, you can beat the market, can you do it consistently, and at large scale? I have a two-part answer to these questions. The first answer depends on who “you” are. If you’re David Shaw, Jim Simons, or George Soros, then we already know the answer from chapter 7: the answer is yes. They can beat the market and they have. By a lot. But there’s a catch (isn’t there always?). Even these extraordinarily accomplished hedge fund managers didn’t have one perfect strategy that worked all the time.

There are several reasons for these funding challenges, but one of the most important is the fact that the drug development process is getting more challenging, even as we become more knowledgeable about the origins of human disease. In fact, it’s because we’re getting smarter that drug development is getter harder and financially riskier. This seems really counterintuitive, especially in the investment world where getting smarter usually means less risk and greater profits—think Warren Buffett, Jim Simons, and David Shaw. Not so in biomedicine. Here’s an example. In recent years, scientists discovered that certain medicines are extremely effective when used together, even though they don’t do much individually. A prominent example of such combination therapies is the highly active antiretroviral therapy (HAART) to treat AIDS.

How to Predict the Unpredictable
by William Poundstone

That’s the secret sauce. Madoff’s investors believed he had achieved annual returns of something like 10 percent a year with low volatility, and had done so over an otherwise volatile decade. Despite what you may have heard, this wasn’t too good to be true. Other money managers have racked up better records. Jim Simons started his Medallion Fund a couple of years before Madoff did. Since 1988, Medallion’s return has averaged 45 percent a year.

The Pattern Seekers: How Autism Drives Human Invention
by Simon Baron-Cohen
Published 14 Aug 2020

The Parents’ Occupations Study was retrospective: it started with a child’s known autism diagnosis and then worked backwards to see if the parents were hyper-systemizers. But could we find any prospective evidence? If you start with hyper-systemizing couples, are they more likely to have an autistic child? I meet couples who have an autistic child all the time. Take couples like Jim Simons, the gifted mathematician and hedge fund entrepreneur, and his wife Marilyn Hawrys, a quantitative economist, who have an autistic daughter. Like many parents of an autistic child, Jim has used his hyper-systemizing to great advantage. He hired mathematicians and computer scientists to create computer models to predict the behavior of the financial markets.

Automate This: How Algorithms Came to Rule Our World
by Christopher Steiner
Published 29 Aug 2012

An employee of Renaissance, the highest concentration of elite quantitative talent in the financial world, is virtually guaranteed several million dollars, if not tens of millions, if they stay on for more than a few years. Employees—and nobody else—get access to Renaissance’s Medallion Fund, which has famously racked up 30 percent or better gains since its inception in the early 1990s. The Medallion Fund employs algorithms trading millions of shares of, as founder Jim Simons puts it, “anything that moves.” At its historical pace the Medallion Fund would turn $100,000 into more than $20 million in just twenty years. When exceedingly smart, calculating people begin turning down Renaissance riches for undetermined outcomes in Silicon Valley, the pendulum has officially swung 100 percent away from Wall Street.

Having said that, getting through four years of engineering school doesn’t take genius; it just takes a little more work and a good base of upper-level math and science in high school. The problem, unfortunately, is that not enough U.S. kids get that foundation of upper-level math before arriving at college. Some, including Renaissance Technology’s founder Jim Simons, say part of the solution would be to hire more of the types of minds that are responsible for our coming algorithm-centric future and put them in the classroom. People can only teach what they understand themselves. Teaching isn’t easy, however. Many of the skills a Google engineer holds do not transfer to unruly collections of sixteen-year-olds.

The Alpha Masters: Unlocking the Genius of the World's Top Hedge Funds
by Maneet Ahuja , Myron Scholes and Mohamed El-Erian
Published 29 May 2012

Now Congress wanted to hear what he had to say about the systemic risks that hedge funds posed to financial markets, and to listen to proposals for regulatory and tax reforms. Paulson was not the only hedge fund manager who had been summoned by the Committee that day, although he was certainly the best performing over the past year. Joining him was fellow subprime winner Phil Falcone, as well as George Soros, the head of Soros Fund Management, Jim Simons of Renaissance Capital, and Ken Griffin of Citadel, all industry legends and billionaires in their own right. Each of these industry titans would have his turn to address the Committee, but right now the floor was Paulson’s. The entire room, indeed, the entire financial world, wanted to hear what this man had to say; his remarks were running live on CNBC, Bloomberg, and, of course, C-SPAN.

Though Paulson & Co. did see some redemption, on the whole investors were quite pleased. At the end of 2010, LCH investments conducted an independent study of hedge funds that produced the greatest net gains for investors since inception. It ranked Paulson & Co. number three, behind only George Soros’s Quantum Endowment Fund (started in 1973) and Jim Simons’s Renaissance Medallion Fund (started in 1982). In his 2010 year-end letter to investors, Paulson proudly included a graphic that listed the top 10 managers, stating, “We are proud that we are number three on the list with over $28 billion in net gains, even though we started our funds 12 and 21 years after Renaissance and Quantum, respectively.”

He was bored with it. It was time to sell up and move on. He decided they should call themselves Hoffmann Investment Technologies in a nod to Jim Simons’s legendary quant shop, Renaissance Technologies, over in Long Island: the daddy of all algorithmic hedge funds. Hoffmann had objected strongly – the first time Quarry had encountered his mania for anonymity – but Quarry was insistent: he saw from the start that Hoffmann’s mystique as a mathematics genius, like that of Jim Simons, would be an important part of selling the product. AmCor agreed to act as prime brokers and to let Quarry take some of his old clients with him in return for a reduced management fee and ten per cent of the action.

Its employees are mostly mathematicians or physicists who program computers to look for anomalies in the market. They certainly appear to have found one in GameStop. The fund’s founder, Jim Simons, a renowned mathematician himself with no previous finance background, is the most successful fund manager of all time. Between 1988 and 2018, his Medallion Fund made an incredible gross annual return of 66 percent a year. That isn’t a typo. Whose money is it—or, rather, was it? In Gregory Zuckerman’s fascinating The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution, the mathematician Henry Laufer, now a billionaire thanks to his stint at Renaissance, was asked that question.

Crypto: How the Code Rebels Beat the Government Saving Privacy in the Digital Age
by Steven Levy
Published 15 Jan 2002

So on February 5, 1973, a high-level meeting was held to review “the status and plans of cryptography within the entire IBM corporation.” As Tritter later summarized the meeting, “It appeared to be broadly agreed . . . that IBM was apparently in the crypto business for keeps, and would have to acquire a corporate expertise in the area. In the meanwhile, attacks on Lucifer were to be intensified.” An outside expert, Jim Simons of the math department at the State University of New York at Stony Brook—who had also practiced cryptography at the Institute for Defense Analysis, the NSA satellite in Princeton—was recruited to organize a concentrated attack on Lucifer. He worked with three researchers from Yorktown Heights for about seven weeks in the late spring of 1973.

This was in 1984, about the same time that RSA was going through its roughest period. Omura and Morris didn’t find the going any easier. “The venture community then couldn’t have cared less about information security,” says Omura. It was only through a private referral that the business plan fell into the hands of Jim Simons, who was not only a mathematician and cryptographer (he’d been one of the early reviewers of Lucifer) but dabbled in venture capital as well. He agreed to help put the newly dubbed Cylink company on its feet. Unlike RSA, which had a mission of getting crypto into the hands of the general public, Cylink focused on securing the communications of big companies, typically those that were government contractors.

But there a plethora of problems come with swinging for the fences. First of all and most obviously, they are incredibly difficult to come by. The 50 largest hedge funds do 50% of all NYSE listed stock trading, and the smallest one spends $100 million annually buying information.19 Imagine that you were physically exchanging stock certificates with Jim Simons of Renaissance Technologies every time you went to buy or sell a stock. This is who you're playing against. The idea that you will stumble upon riches by dumb luck alone is possible, but a little naive. The second problem, and this is a problem we all wish for, is that once you've experienced outsized success in the stock market, you crave a similar rush.

The Psychology of Money: Timeless Lessons on Wealth, Greed, and Happiness
by Morgan Housel
Published 7 Sep 2020

Effectively all of Warren Buffett’s financial success can be tied to the financial base he built in his pubescent years and the longevity he maintained in his geriatric years. His skill is investing, but his secret is time. That’s how compounding works. Think of this another way. Buffett is the richest investor of all time. But he’s not actually the greatest—at least not when measured by average annual returns. Jim Simons, head of the hedge fund Renaissance Technologies, has compounded money at 66% annually since 1988. No one comes close to this record. As we just saw, Buffett has compounded at roughly 22% annually, a third as much. Simons’ net worth, as I write, is $21 billion. He is—and I know how ridiculous this sounds given the numbers we’re dealing with—75% less rich than Buffett.

The Aristocracy of Talent: How Meritocracy Made the Modern World
by Adrian Wooldridge
Published 2 Jun 2021

The meritocratic idea is shaping society from top to bottom. A growing proportion of great fortunes are in the hands of people with outstanding brain power: computer geeks such as Bill Gates (Microsoft) and Mark Zuckerberg (Facebook) or financial wizards such as George Soros (who pioneered hedge funds) and Jim Simons (who helped to found computer-driven ‘quant investing’).9 The world’s richest man, Jeff Bezos, graduated summa cum laude and Phi Beta Kappa from Princeton and makes a point of surrounding himself with academic super-achievers. High-IQ types are even thriving in the more rough-and-ready corners of capitalism: six of the seven biggest Russian oligarchs of the 1990s earned degrees in maths, physics or finance before becoming natural-resource tycoons.

Quantitative Value: A Practitioner's Guide to Automating Intelligent Investment and Eliminating Behavioral Errors
by Wesley R. Gray and Tobias E. Carlisle
Published 29 Nov 2012

A PEEK INSIDE THE BLACK BOX Many investors legitimately fear that quantitative analysis is an inscrutable “black box,” from which emanate incomprehensible investment ideas, many of which don't look like winners. While we know the past results for Quantitative Value have been outstanding, it often feels like one or more of the current crop of stocks selected by the model are particularly weak and should be avoided. Surely we can pick and choose from the model's output? Jim Simons disagrees. The billionaire mathematician turned quantitative hedge fund titan, believes that much of his success is attributable to his strict adherence to the output of his models6: Did you like what the model said or did you not like what the model said? That is a hard thing to backtest. If you are going to trade using models, you just slavishly use the models; you do whatever the hell it says no matter how smart or dumb you think it might be at that moment.”

My mind starts to wander, mulling over the influence of the quant strategies on the markets. They’re a new force. Go ask Jim Simons. He’s the most successful money maker in the history of modern finance and an amazing European-style chain smoker. There is an old tale—who knows if it’s true or not—that Simons was visiting Goldman.

And the particular way in which Mercer had taken this worldview and applied it at Renaissance Technologies—by stringing together a series of models that functioned in tandem—was the same way that Bannon thought about politics and hoped to attack the system. The model that Mercer believed in so fiercely was devised by a mathematician and former code breaker for the Pentagon’s secretive Institute for Defense Analyses named Jim Simons. In the late 1970s, Simons was chairman of the math department at Stony Brook University on Long Island and an avid amateur speculator in commodities (he spent his wedding money trading soybean futures). Believing that he could bring mathematical rigor to the gut-driven practice of commodities trading, Simons began recruiting some fellow mathematicians and code breakers to help him automate the process of finding the best trades.

Market Sense and Nonsense
by Jack D. Schwager
Published 5 Oct 2012

There are too many examples of extraordinary performance in the markets to be consistent with a theoretical framework that asserts that the only way to beat the market is by chance. We need consider only one such track record to make the point: the Renaissance Medallion fund, which was headed by the mathematician Jim Simons and supported by a brilliant team of mathematicians and scientists. Over a 19-year period (1990 to early 2009) for which we have results, the fund realized an average monthly gross return of 4.77 percent with 90 percent of the months being positive. (We used gross returns in our analysis instead of net returns because we are interested in calculating the probability of attaining the track record, not the implied return to investors after fees.)

Back in 1937, the beginnings of an idea for a bold stunt that might save their town spread around Newlyn, inspired by the history of the Cornish revolts, this time in the form of a protest to London – not across land, but over the seas. A crew of nine upstanding Newlyn men came forward ready to set sail for Westminster: Cecil Richards, W. (Swell) Richards, skipper, J. S. (Jimmy Strick) Matthews, Ben Batten, J. P. (Sailor Joe) Harvey; W. (Billy Bosun) Roberts (a preacher), J. (Jim) Simons, J. H. (Jan Enny) Tonkin and W.H. (Skinny) Williams. The Rosebud, owned by the Richards’ brothers, was to be the chosen vessel.

To be clear, we aren’t saying that investors like Peter Lynch, Ray Dalio, and Jim Simons owe their success to luck alone—only that when thinking about success stories, we should keep in mind that most of what we hear is about people like them.12 Documenting the true causes of success requires more than a clever narrative. We have to think about the planes that never came back, the cards that weren’t picked, and the other outcomes that a psychic performer could have accommodated.

System Error: Where Big Tech Went Wrong and How We Can Reboot
by Rob Reich , Mehran Sahami and Jeremy M. Weinstein
Published 6 Sep 2021

Increasingly, AI is used to power ever-more-sophisticated models for trading equities, commodities, and derivatives. Called “quantitative hedge funds,” these systems use algorithmic techniques, frequently powered by machine learning models, to make split-second transactions on everything from Apple stock to zinc futures. One of the pioneers in this area, Renaissance Technologies, was founded by Jim Simons, a mathematics PhD who had spent time working at the National Security Agency on code breaking—a somewhat different but equally quantitative form of pattern recognition. Renaissance’s Medallion fund has generated more than $100 billion in profits since the company’s founding in 1982. Indeed, the world of finance has shifted in the wake of technological developments, as financial services firms increasingly focus on customer relationship management and access to private funds utilizing quantitative technologies.

Massive amounts of technology have been deployed to automate the work of actually buying the assets once the decisions have been made (and then keeping track of them over time), but these decisions were almost always made by minds, not machines. This started to change in the 1980s when pioneers like Jim Simons (one of the most accomplished mathematicians of his generation) and David Shaw (a computer scientist) founded, respectively, Renaissance Technologies and D. E. Shaw to use machines to make investment decisions. These companies sifted through large amounts of data, built and tested quantitative models of how assets’ prices behaved under different conditions, and worked to substitute code and math for individual judgment about what and when to buy.

Unknown Market Wizards: The Best Traders You've Never Heard Of
by Jack D. Schwager
Published 2 Nov 2020

In those days, most software testing was done manually, which was a very time-consuming and error-prone process. We created software that automated the testing using a methodology that we were able to patent. Ultimately, Segue agreed to buy our technology in exchange for stock, and our group was merged into Segue. An interesting side note is that Jim Simons of Renaissance was the principal investor in Segue and was involved in the merger negotiations, which resulted in our getting stock in Segue in exchange for our technology. At the time, did you know who Simons was? Someone told me he was a rich guy who was a commodity trader. I didn’t even know what a commodity trader was.

Investing Amid Low Expected Returns: Making the Most When Markets Offer the Least
by Antti Ilmanen
Published 24 Feb 2022

Related work by Taleb (2001), Kahneman (2011), and Mauboussin (2012) highlights the difficulty of disentangling luck versus skill, as well as the common tendency to underestimate the role of luck in outcomes. 3 For example, Warren Buffett's track record is about long-run success, not about implausible short-run consistency. Exceptions to this rule typically involve return smoothing (which conceal true economic fluctuations in private asset funds) or effective market-making gains (high-frequency liquidity provision strategies are partly behind the success of Jim Simons' most famous fund, Medallion, which is anyway closed to outside investors). 4 This is why I could not publish a manuscript “Patience,” now in Chapter 9. It would have sounded too self-serving and outright irritating to some suffering investors. So please don't think I consider patience easy. It is fair to ask underperforming managers if a systematic strategy is broken or a discretionary manager has lost her touch.

But where would that have left other investors, ones who weren’t so fortunate to have Buffett as their money manager? Now imagine if Buffett were to approach Markowitz, asking “What could you do to help me?” Markowitz’s response would be “Here is a framework and an approach for portfolio management.” We readily acknowledge the investment success of Buffett, John Templeton, Peter Lynch, David Shaw, Jim Simons, George Soros, and many other great investors whose styles and approaches to investment aren’t easily replicated. However, the academic financial research by Markowitz as well as his fellow Nobel laureates such as James Tobin, Paul Samuelson, Bill Sharpe, Myron Scholes, Bob Merton, Gene Fama, and Bob Shiller and by other exceptional researchers has created a framework and repeatable process for investors that has led to the democratization of investment management.

Antifragile: Things That Gain From Disorder
by Nassim Nicholas Taleb
Published 27 Nov 2012

Now, the more asymmetries there are between the something and the function of something, then the more difference there is between the two. They may end up having nothing to do with each other. This seems trivial, but there are big-time implications. As usual science—not “social” science, but smart science—gets it. Someone who escaped the conflation problem is Jim Simons, the great mathematician who made a fortune building a huge machine to transact across markets. It replicates the buying and selling methods of these sub–blue collar people and has more statistical significance than anyone on planet Earth. He claims to never hire economists and finance people, just physicists and mathematicians, those involved in pattern recognition accessing the internal logic of things, without theorizing.

Area 51: An Uncensored History of America's Top Secret Military Base
by Annie Jacobsen
Published 16 May 2011

Munir Redfa’s MiG had been nicknamed the doughnut because the jet fighter’s nose had a round opening in it, like a doughnut’s. It was the first advanced Soviet fighter jet ever to set its wheels down on U.S. soil. Colonel Slater, overseeing Black Shield in Kadena at the time, remembers getting a call in the middle of the night from one of his staff, Jim Simon. “Simon called me up all excited and said, ‘Slater, you are not going to believe this!’ He told me about the MiG. How it landed at [Area] 51 in the middle of the night, hidden inside a cargo plane. How it was accompanied by someone from a foreign government. Simon couldn’t get over it and I couldn’t wait to see it,” Slater remembers.

House of Cards: A Tale of Hubris and Wretched Excess on Wall Street

We were putting out fires every day, all day every day, for firms that wouldn't take assignments, or wouldn't take our name in the foreign exchange markets, or wherever, either localized within departments or at the corporate level. I'd have done the same thing.” At least two major hedge funds began pulling their cash from the firm. “The prime brokerage withdrawals began in earnest that Tuesday night,” Boyd explained. “I think the two big funds that kicked it all off were Renaissance Technologies—Jim Simons's $30 billion fund. I had two or three people tell me that he pulled, and I think he had $20 billion [at Bear]—and I think Highbridge did, too.” (Since September 2004, JPMorgan Chase has controlled Highbridge Capital Management, a hedge fund with around $35 billion in capital.) To be sure, the cash was theirs and they were entitled to it at any moment, and this cash was not to be confused with Bear's own corporate cash, which was in a separate, segregated account.
