How I Became a Quant: Insights From 25 of Wall Street's Elite
by Richard R. Lindsey and Barry Schachter
Published 30 Jun 2007

I did not know—and still do not know—exactly what they did, but whenever his group was mentioned, people were abuzz with excitement. Peter was outgoing and friendly and made an effort to get to know the quant research guys. We became friends and he was eventually a big influence on my decision to pursue quantitative trading. Quant Research and the Mathematics of Portfolio Trading I want to start with some general comments about how I view research in financial mathematics. I believe that one incredibly important application of quantitative research is in improving business processes. Many business units in finance are governed by rules of thumb and best practices that have never been fully analyzed.

The Quants
by Scott Patterson
Published 2 Feb 2010

As stocks tumbled, pressure increased on portfolio insurers to sell futures, racing to keep up with the widely gapping market in a devastating feedback loop. The arbs scrambled to put on their trades but were overwhelmed: futures and stocks were falling in unison. Chaos ruled. Fischer Black watched the disaster with fascination from his perch at Goldman Sachs in New York, where he’d taken a job managing quantitative trading strategies. Robert Jones, a Goldman trader, dashed into Black’s office to report on the carnage. “I put in an order to sell at market and it never filled,” he said, describing a frightening scenario in which prices are falling so fast there seems to be no set point where a trade can be executed.

Then he quit. “Who the fuck are you, and why the fuck do you get an office?” “I’m fucking Peter Muller, and I’m fucking pleased to meet you.” Muller stared bullets at the wiseass Morgan Stanley salesman who’d barged into his office as though he owned it. Muller had only recently begun setting up a quantitative trading group at Morgan, and this was the reception he got? It had been like this since the day he arrived at the bank. After accepting a job at Morgan, and with it an incredible increase in pay, he’d given notice at BARRA and taken six weeks of R&R, spending most of it in Kauai, the lush, westernmost island of Hawaii.

The party in Paris included festivities at the Louvre and a rehearsal dinner at the Musée d’Orsay. It was good to be Ken Griffin. Perhaps too good. MULLER Just as Griffin was starting up Citadel in Chicago, Peter Muller was hard at work at Morgan Stanley in New York trying to put together his own quantitative trading outfit using the models he’d devised at BARRA. In 1991, he pulled the trigger, flipping on the computers. It was a nightmare. Nothing worked. The sophisticated trading models he’d developed at BARRA were brilliant in theory. But when Muller actually traded with them, he ran into all sorts of problems.

But even for readers who learned about this kind of trading from the mainstream media before, it is worth clearing up some common misconceptions. Quantitative trading, also known as algorithmic trading, is the trading of securities based strictly on the buy/sell decisions of computer algorithms.

The computer algorithms are designed and perhaps programmed by the traders themselves, based on the historical performance of the encoded strategy tested against historical financial data. Is quantitative trading just a fancy name for technical analysis, then? Granted, a strategy based on technical analysis can be part of a quantitative trading system if it can be fully encoded as computer programs. However, not all technical analysis can be regarded as quantitative trading. For example, certain chartist techniques such as “look for the formation of a head and shoulders pattern” might not be included in a quantitative trader’s arsenal because they are quite subjective and may not be quantifiable. Yet quantitative trading includes more than just technical analysis.

This is also a dangerous emotion to bring to independent quantitative trading. As I hope to persuade you in this chapter and in the rest of the book, instant wealth is not the objective of quantitative trading. The ideal independent quantitative trader is therefore someone who has some prior experience with finance or computer programming, who has enough savings to withstand the inevitable losses and periods without income, and whose emotion has found the right balance between fear and greed. THE BUSINESS CASE FOR QUANTITATIVE TRADING A lot of us are in the business of quantitative trading because it is exciting, intellectually stimulating, financially rewarding, or perhaps it is the only thing we are good at doing.

Traders, Guns & Money: Knowns and Unknowns in the Dazzling World of Derivatives
by Satyajit Das
Published 15 Nov 2006

A few firms, like Salomon Brothers, continued to undertake serious research, producing high quality material and introducing sophisticated analytical tools, but they were the exceptions. Serious research moved into the private domain and was mainly applied to prop trading. Salomon’s research effort drove the quantitative trading of its Arbitrage Group and subsequently that of its alumni in Long Term Capital Management (LTCM). But for the most part, the research distributed by investment banks to clients evolved into ‘puffery’ designed to get the client to trade. Analysts were expected to build profile for the firm and for themselves.

The premise of that edition – that we considered these techniques “the future of trading” – is more true today than it ever was. In the intervening four years, we at WorldQuant have seen remarkable growth in our development of predictive algorithms for quantitative trading – we call them “alphas” – powered by an ever-rising volume and variety of available data, an explosion in computer hardware and software, and increasingly sophisticated techniques that allow us to create and deploy a higher volume and quality of alphas. Today, at WorldQuant, we have produced over 20 million alphas, a number that continues to grow exponentially as we hunt for ever-weaker predictive signals.

But change is a constant, and the task is never done. Igor Tulchinsky June 2019 Preface (to the Original Edition) This book is a study of the process of finding alphas. The material is presented as a collection of essays, providing diverse viewpoints from successful quants on the front lines of quantitative trading. A wide variety of topics is covered, ranging from theories about the existence of alphas, to the more concrete and technical aspects of alpha creation. Part I presents a general introduction to alpha creation and is followed by a brief account of the alpha life cycle and insights on cutting losses.

In Part IV, we introduce you to WebSim, a web-based alpha development tool. We invite all quant enthusiasts to utilize this free tool to learn about alpha backtesting (also known as alpha simulation) and ultimately to create their own alphas. Finally, in Part V, we present an inspirational essay for all quants who are ready to explore the world of quantitative trading. Acknowledgments In these pages, we present a collection of chapters on the algorithmic-­ based process of developing alphas. The authors of these chapters are WorldQuant’s founder, directors, managers, portfolio managers, and quantitative researchers. This book has two key objectives: to present as many state-of-the-art viewpoints as possible on defining an alpha, and the techniques involved in finding and testing alphas.

Nerds on Wall Street: Math, Machines and Wired Markets

There were all sorts of uses for it, ranging from market surveillance to proprietary trading, but it just did what you told it to do, no matter how stupid that might be. If you had actually found the holy grail of quantitative trading, but had made only one little mistake—you were buying when you should sell, and selling when you should buy—the system would never notice. But a genetic algorithm would notice this kind of sign error, along with a host of other mistakes and miscalibrations. It seemed to be an ideal tool for tuning, refining, and evolving quantitative investment and trading strategies.

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

As a result, Morgan Stanley didn’t have strong legal grounds to stop Frey’s trading. With some trepidation, he ignored Morgan Stanley’s continuing threats and began trading. * * * = By 1990, Simons had high hopes Frey and Kepler might find success with their stock trades. He was even more enthused about his own Medallion fund and its quantitative-trading strategies in bond, commodity, and currency markets. Competition was building, however, with some rivals embracing similar trading strategies. Simons’s biggest competition figured to come from David Shaw, another refugee of the Morgan Stanley APT group. After leaving the bank in 1988, the thirty-six-year-old Shaw, who had received his PhD from Stanford University, was courted by Goldman Sachs and was unsure whether to accept the job offer.

Privately, Englander wondered if Simons’s true fear was the possibility of additional departures from his firm, rather than any theft. Simons wouldn’t share much with his rival. He and Renaissance sued Englander’s firm, as well as Volfbeyn and Belopolsky, while the traders brought countersuits against Renaissance. Amid the hostilities, Volfbeyn and Belopolsky set up their own quantitative-trading system, racking up about $100 million of profits while becoming, as Englander told a colleague, some of the most successful traders Englander had encountered. At Renaissance, Volfbeyn and Belopolsky had signed nondisclosure agreements prohibiting them from using or sharing Medallion’s secrets.

There’s reason to believe computer traders can amplify or accelerate existing trends. Author and former risk manager Richard Bookstaber has argued that risks today are significant because the embrace of quant models is “system-wide across the investment world,” suggesting that future troubles for these investors would have more impact than in the past.12 As more embrace quantitative trading, the very nature of financial markets could change. New types of errors could be introduced, some of which have yet to be experienced, making them harder to anticipate. Until now, markets have been driven by human behavior, reflecting the dominant roles played by traders and investors. If machine learning and other computer models become the most influential factors in markets, they may become less predictable and maybe even less stable, since human nature is roughly constant while the nature of this kind of computerized trading can change rapidly.

High-Frequency Trading: A Practical Guide to Algorithmic Strategies and Trading Systems
by Irene Aldridge
Published 1 Dec 2009

The third part addresses the details of modeling high-frequency trading strategies. The fourth part describes the steps required to build a quality high-frequency trading system. The fifth and last part addresses the issues of running, monitoring, and benchmarking highfrequency trading systems. The book includes numerous quantitative trading strategies with references to the studies that first documented the ideas. The trading strategies discussed illustrate practical considerations behind high-frequency trading. Chapter 10 considers strategies of the highest frequency, with position-holding periods of one minute or less. Chapter 11 looks into a class of high-frequency strategies known as the market microstructure models, with typical holding periods seldom exceeding 10 minutes.

As with technical trading, fundamental trading entails buying a security the price of which was deemed too low relative to its analytically determined fundamental value and selling a security the price of which is considered too high. Like technical trading, fundamental trading can also be applied at any frequency, although price formation or microstructure effects may result in price anomalies at ultrahigh frequencies. Finally, quant (short for quantitative) trading refers to making portfolio allocation decisions based on scientific principles. These principles may be fundamental or technical or can be based on simple statistical relationships. The main difference between quant analyses and technical or fundamental styles is that quants use little or no discretionary judgments, whereas fundamental analysts may exercise discretion in rating the management of the company, for example, and technical analysts may “see” various shapes appearing in the charts.

Chaos Kings: How Wall Street Traders Make Billions in the New Age of Crisis
by Scott Patterson
Published 5 Jun 2023

The exact timing of such interventions is typically unforeseen by economic actors like banks and corporations, and the fallout from them can be chaotic. So while the models were able to make precise forecasts based on past events, the chaotic shocks often made those precise forecasts practically worthless. In 1986, Litterman was contacted by Goldman Sachs. The firm had been dabbling in quantitative trading strategies. Its most prominent hire was the economist Fischer Black, co-creator of the Black-Scholes option pricing model and a staunch, practically religious believer in the efficient market hypothesis. In 1986, Litterman sat down for an interview with Black. “So Bob, you’re an econometrician,” he said.

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

Much like the Simons team, he pursued numerical precision with a zealous intensity: His staff soon discovered that it was no good telling him that a programming task might take three to eight weeks; you had to say that it would take 5.25, but with an error of two weeks.7 Yet for all these similarities, there were differences between Shaw and Simons too. These proved to be significant. Shaw got into finance via Morgan Stanley’s proprietary trading desk, which hired him to create a computer system to support its quantitative trading. It was 1986, and big things were stirring at Morgan. The firm’s secretive Analytical Proprietary Trading unit ran a computerized effort to profit from short-run liquidity effects in stock markets. As Michael Steinhardt had discovered in the 1970s, a big sell order from a pension fund could push a stock’s price out of line; provided that there was no information behind the sale—that is, provided that the pension fund was selling because it needed cash rather than because it was reacting to bad news—Steinhardt could profit by buying and holding the stock until it rose back to its previous level.

Medallion therefore closed to new outside investors in 1993, and by the 2000s the $6 billion or so in the fund consisted almost entirely of employees’ money.34 But the very existence of Medallion had a halo effect on the rest of the industry, offsetting the blow to the reputation of black-box trading administered by the collapse of Long-Term Capital. Each time Simons’s picture appeared on the cover of a financial magazine, more eager institutional money flooded into quantitative trading systems. Simons himself capitalized on this phenomenon. In 2005 he launched a new venture, the Renaissance Institutional Equities Fund, which was designed to absorb an eye-popping $100 billion in institutional savings. The only way this huge amount could be manageable was to branch out from short-term trading into more liquid longer-term strategies—and since pure pattern recognition works best for short-term trades, it followed that Simons was offering a fund that would rely on different sorts of signal—ones that might already have been mined by D.

In evolutionary terms, the markets were adapting. In fact, the markets may have been adapting specifically to the presence of D. E. Shaw & Co., although Shaw modestly downplays that possibility: “Over time, things evolved. I don’t know how much of that was due to our influence. The general comment I can make is that quantitative trading became more challenging with every passing year.” In fact, Shaw inspired legions of talented computer scientists, mathematicians, and other quants to pursue careers in finance, raising the level of play in this highly competitive field. After transforming the hedge fund industry into a quantitative discipline that now employs thousands of engineers, Shaw decided to apply his intellectual gifts to another field.

On Wednesday, September 10, the SEC was scheduled to hold a public meeting to vote on a staff plan for calming down witching hour Fridays. The proposal asked that brokers send orders seeking the day’s closing price, so-called market-on-close orders, to the trading floor a half hour before the closing bell, so any order imbalances could be publicized. That was as far as John Shad was willing to go in meddling with the new quantitative trading strategies. Before that public session, however, Shad convened a “super-executive session,” a meeting open only to the commissioners and a few key members of the enforcement staff. According to one account, this meeting was the first update on the Boesky case given to Shad or any other commissioner since earlier that summer.

These products, which were once expensive to implement and maintain, are now becoming accessible to new entrants due to price pressure, for example, hedge funds and smaller investment management firms. Portware and FlexTrade are focusing on hedge funds with solutions that allow users to customize quantitative trading strategies alongside traditional risk arbitrage and long/short strategies. As the market for high-priced custom implementation becomes saturated, vendors will shift their focus to midtier asset managers where once only the largest financial firms could justify the expense. More players will implement electronic access to markets integrating trading and portfolio management suites.

The Ethical Algorithm: The Science of Socially Aware Algorithm Design
by Michael Kearns and Aaron Roth
Published 3 Oct 2019

We’ve spent many hours talking to lawyers, regulators, economists, criminologists, social scientists, technology industry professionals, and many others about the issues raised in these pages. We’ve provided testimony and input to congressional committees, corporations, and government agencies on algorithmic privacy and fairness. And between us we have extensive, hands-on professional experience in areas including quantitative trading and finance; legal, regulatory, and algorithmic consulting; and technology investing and start-ups—all of which are beginning to confront the social issues that are our themes here. We are, in short, modern computer scientists. We also know what we are not, and should not pretend to be. We are not lawyers or regulators.

If we then change the weightings—say, to 1/4 times error plus 3/4 times the unfairness score—we will find another point on the Pareto frontier. So by exploring different combinations of our two objectives, we “reduce” our problem to the single-objective case and can trace out the entire frontier. While the idea of considering cold, quantitative trade-offs between accuracy and fairness might make you uncomfortable, the point is that there is simply no escaping the Pareto frontier. Machine learning engineers and policymakers alike can be ignorant of it or refuse to look at it. But once we pick a decision-making model (which might in fact be a human decision-maker), there are only two possibilities.

Crapshoot Investing: How Tech-Savvy Traders and Clueless Regulators Turned the Stock Market Into a Casino
by Jim McTague
Published 1 Mar 2011

A third strategy, called event trading, tried to capitalize on the news of the day and predict which direction the markets would take in reaction to the latest development. Harvey Houtkin used to instruct his trading students, “The trend is your friend,” and this was a variation of that theme. Large quantitative-trading firms such as Medallion engaged heavily in this type of momentum trading. The fourth strategy was old-fashioned arbitrage, in which the traders attempted to find price discrepancies between seemingly unrelated instruments, like stocks and sugar futures, for instance. Generally speaking, the algorithms compared data of past stock and commodities movements to build an understanding of how they might behave in the present.

These strategies exacerbated market volatility by driving stocks much higher or lower than they would have moved if investors merely were weighing the underlying fundamentals of the securities. Yaroshevsky saw things occurring in the equities market that had never occurred in the past, like the market beginning to rise robustly during a recession, as it did early in 2009. The rise was driven purely by quantitative trading, he argued. Credit was first extended by the regulators at the Federal Reserve to the bankers and “into the more capable hands of the quantitative geniuses,” he chuckled. Their trading drove the market higher and culminated in the Flash Crash. It wasn’t deliberate market manipulation, in his view.

Efficiently Inefficient: How Smart Money Invests and Market Prices Are Determined
by Lasse Heje Pedersen
Published 12 Apr 2015

While discretionary trading has the advantages of a tailored analysis of each trade and the use of soft information such as private conversations, its labor-intensive method implies that only a limited number of securities can be analyzed in depth, and the discretion exposes the trader to psychological biases. Quantitative trading has the advantage of being able to apply a trading idea to thousands of securities around the globe, benefiting from significant diversification. Furthermore, quants can apply their trading ideas with the discipline of a robot. Discipline is important for all traders, but as the saying goes, Have a rule.

Dedicated short bias hedge funds focus on findings stocks that are about to go down, looking for frauds, overstated earnings, or poor business plans. Dedicated short bias hedge funds rely on a fundamental analysis of companies in a similar way to other discretionary equity investors. Discretionary trading can be seen in contrast to quantitative trading, which invests systematically based on a model. Both types of traders may seek lots of data and use valuation models, but whereas discretionary traders make their final trading decisions based on human judgment, quantitative investors trade systematically with minimal human interference. Quantitative investors gather data, check the data, feed it into a model, and let the model send trades to the exchanges.1 Quants try to develop a small edge on each of many small diversified trades using sophisticated processing of ideas that cannot be easily processed using non-quantitative methods.

Discretionary trading has the advantages of a tailored analysis of each trade and the use of a lot of soft information such as private conversations, but its labor-intensive method implies that only a limited number of securities can be analyzed in depth, and the discretion exposes the trader to psychological biases. Quantitative trading has the advantage of discipline, an ability to apply a trading idea to a wide universe of securities with the benefits of diversification, and efficient portfolio construction, but it must rely only on hard data and the computer program’s limited ability to incorporate real-time judgment. While the three forms of equity investment have several differences, each relies on an understanding of equity valuation.

Both of these careers also come with a high chance of dropping out, since at each stage, if you fail to be promoted, you’ll probably have to switch into a different job with lower pay. Even taking this into account, however, they’re still among the career paths with the highest expected earnings. Tech entrepreneurship and quantitative trading in hedge funds offer even higher expected earnings, though tech entrepreneurship comes with even higher risks (entrepreneurs have less than a 10 percent chance of ever selling their shares in the company at profit) and quantitative trading requires exceptionally strong mathematical skills. Among less risky careers, medicine is probably the highest-earning option, especially in the United States, though earnings are probably less than in finance.

Breaking Twitter: Elon Musk and the Most Controversial Corporate Takeover in History

Elon was no stranger to the mythology that had grown up around the kid: Sam Bankman-Fried, or SBF as he was generally known in the tech press, was considered one of the most brilliant young entrepreneurs of the past decade. After first making a name for himself at Jane Street Capital, then starting his own quantitative trading firm, called Alameda Research, at thirty, SBF had founded FTX, one of the fastest-growing crypto exchanges in the world. The stories about SBF were legendary, and unavoidable. How he’d first pitched FTX to a room full of Sequoia Capital VCs, waxing poetic about making his exchange “a place where you can do anything you want with your next dollar,” from buying crypto to art to goddamn produce, all the while his head hovered inches above his laptop, never once breaking from the screen to make eye contact.

Only Humans Need Apply: Winners and Losers in the Age of Smart Machines
by Thomas H. Davenport and Julia Kirby
Published 23 May 2016

The process we’re describing, of machines taking the high-end cognitive parts of work and turning people into a sort of human user interface, is occurring across many professional realms. Actual decision-making roles have been ceded to computers—and they are doing pretty well in those roles, despite some occasional hiccups. “Program trading” (also known as high-frequency, algorithmic, or quantitative trading) of equities and fixed-income investments, for example, is widespread on Wall Street and around the financial world. It’s one of the reasons why the New York Stock Exchange is so quiet today. Decisions about which stocks and bonds to buy for what price used to be made by human traders but are now largely made by computer.

Value Investing: From Graham to Buffett and Beyond
by Bruce C. N. Greenwald , Judd Kahn , Paul D. Sonkin and Michael van Biema
Published 26 Jan 2004

And he followed Graham's practice of comparing two companies in the same industry, like Bethlehem and Crucible Steel, to see which was cheaper on an intrinsic value basis. Their focus was the balance sheet, not the income statement. They were able to discuss these ideas and pick up other suggestions from a community of value investors that had formed around Graham. One lasting interest of Graham and this circle was the search for quantitative trading formulas that could be used to direct market investment strategies in a disciplined way. Heilbrunn contributed to the development of these kinds of rules in an article published in 1958. The method prefigured many of the formulas used by quantitatively oriented value investors today. Heilbrunn examined the price, earnings, and dividend histories of specific companies to establish the ranges of the price to earnings (P/E) multiple and the dividend yield within which the securities had traded.

ZBI traded only with internal funds—those of the Ziff family, of publishing fame—in what is termed in the investment world a family office; it was never chasing after other hedge funds’ investor dollars. Not long after I joined ZBI I moved from risk management to portfolio management. I redirected the efforts of a small group of PhDs who had been providing quantitative analysis for the traditional portfolio managers toward running an internal portfolio based on quantitative trading models. While the trading center for Moore was macro strategies, at ZBI the center was equities, and the portfolio I managed was an equity portfolio. So between this and Scribe Reports, I had moved solidly into the world of equity hedge funds, and I found equities to be a very attractive market.

More and more lines of business involved technical, quantitative computer-driven financial transactions, running twenty-four hours a day, designed by people with advanced academic training whom the firm had hired. Dick Fisher, and John Mack after him, liked to say that three forces were driving the new financial world: deregulation, globalization, and technology. Morgan Stanley pursued enthusiastically anything that seemed attuned to those forces. The firm started a quantitative trading division run by a team of mathematicians. It invented new kinds of derivatives. It became a force in Silicon Valley, where its star analyst, Mary Meeker, wrote optimistic reports about the future of technology and also made Morgan Stanley the leading manager of the initial public offerings of companies like Netscape and Google.

Reinventing Organizations: A Guide to Creating Organizations Inspired by the Next Stage of Human Consciousness
by Frederic Laloux and Ken Wilber
Published 9 Feb 2014

The argument sounds reasonable, so how come none of the pioneer Teal Organizations use multiple-bottom-line accounting systems? I think the following is at play: multiple bottom lines may help to overcome the fixation on profits alone, but the concept is still rooted in Orange thinking, where decisions are informed only by quantitative trade-offs, by weighing costs and benefits. From an Evolutionary-Teal perspective, not everything needs to be quantified to discern a right course of action. Of course, there are valuable insights to be gained from measuring how a company’s actions impact the environment and society (and for that reason, multiple bottom lines may well become a standard way of reporting in the future).

Making Globalization Work
by Joseph E. Stiglitz

Even putting this statistical debate aside, it is striking that even NAFTA advocates suggest that it has had at most a small effect on growth, even in a period in which, because of the Mexican crisis, trade was vital.Mexico’s joining the WTO in January 1995 may have made more of a difference in some respects than NAFTA, because it limited what the government could do in the aftermath of the 1994–95 crisis. (In earlier crises, the government had imposed numerous quantitative trade restrictions, which critics say had long-lasting adverse effects.).NAFTA proponents sometimes argue that NAFTA’s real contribution was opening up investment, not trade. But, critics say, while the effect on overall foreign investment is uncertain, some aspects of foreign investment may have contributed to Mexico’s slow growth.

The Contrarian: Peter Thiel and Silicon Valley's Pursuit of Power
by Max Chafkin
Published 14 Sep 2021

Macro investors might only try to make a trade a week—an approach that fit perfectly with Thiel’s unusual combination of indecisiveness and high tolerance for risk. “His worldview is that if you get one big thing right, and move hard with conviction, then nothing else matters,” said an early Clarium employee. It also fit with his appetite for power: Quantitative trading’s effects on the market are in most cases hard to parse; macro investors, because their bets tend to be large, involving entire economies, can move—and in rare cases, destroy—those economies. If you bet enough money on a recession as a macro investor, you may end up causing one. Thiel’s choice of strategy was contrarian in another way.

There is, of course, no particular reason why a sperm competition gene should happen to cause malfunction of the liver but, as already pointed out, most mutations are deleterious, so some undesirable side effect is pretty likely. Why does Crow assert that selection for good health is much less effective than selection by competition among sperm cells? There must inevitably be a quantitative trade-off involving the magnitude of the effect on health. But, that aside, and even allowing for the controversial possibility that only a minority of sperms are viable (Cohen 1977), the argument appears to have force because the competition between sperm cells in an ejaculate would seem to be so fierce.

Goldman Sachs also had a large proprietary trading desk generating almost 50% of the firm’s profits. For example, in 2007, the trading and principal investments group made 64% of Goldman Sach’s revenues.8 This proprietary trading desk would have to be shut down. In fact, Morgan Stanley has already begun preparing for these new rules and the head of their quantitative trading desk, Peter Muller, and the rest of his team have left Morgan to start their own hedge fund. Some Thoughts The purpose of the Volker rule is to prevent banks that are protected by the public sector safety net from having risks due to investments in hedge funds and/or proprietary trading desks which can increase their risk substantially.
