The success of the Apollo 11 mission gave Nixon an excuse to divert funds from NASA and other research groups to the military effort. By 1971, NASA’s budget was less than half of what it had been in 1966 (in real terms). Meanwhile, college enrollment began to drop, largely because the Baby Boom years were over. Once the “Boomers” had graduated, universities stopped hiring new faculty members. Emanuel Derman was a South African physicist who experienced this funding roller coaster firsthand. He entered graduate school, at Columbia University, in 1966, at the high point of U.S. science funding. He worked on experimental particle physics — a field far from NASA’s central interests, but a beneficiary of the uptick in government support for physics nonetheless.

Whereas in the years leading up to the crash the Black-Scholes model seemed to get options prices exactly right, in virtually all contexts and all markets, after the crash certain discrepancies began to appear. These discrepancies are often called the volatility smile because of their distinctive shape in certain graphs. The smile appeared suddenly and presented a major mystery for financial engineers in the early 1990s, when its prevalence was first recognized. Notably, Emanuel Derman came up with a way of modifying the Black-Scholes model to account for the volatility smile, though he never came up with a principled reason why the Black-Scholes model had stopped working. Mandelbrot’s work, however, offers a compelling explanation for the volatility smile. One way of interpreting the smile is as an indication that the market believes large shifts in prices are more likely than the Black-Scholes model assumes.

The Quants
by Scott Patterson
Published 2 Feb 2010

The volatility smile perplexed Wall Street’s quants. For one thing, it made a hash of their carefully calibrated hedging strategies. It also raised questions about the underlying theory itself. “I realized that the existence of the smile was completely at odds with Black and Scholes’s 20-year-old foundation of options theory,” wrote Emanuel Derman, a longtime financial engineer who worked alongside Fischer Black at Goldman Sachs, in his book My Life as a Quant. “And, if the Black-Scholes formula was wrong, then so was the predicted sensitivity of an option’s price to movements in its underlying index. … The smile, therefore, poked a small hole deep into the dike of theory that sheltered options trading.”

The mad scientists who’d been running wild in the heart of the financial system for decades had finally done it: they’d blown it up. On a frigid day in early January 2009, several weeks after addressing the crowd of hopeful quants at the Renaissance Hotel, Wilmott boarded a plane at Heathrow Airport in London and returned to New York City. In New York, he met with über-quant Emanuel Derman. A lanky, white-haired South African, Derman headed up Columbia University’s financial engineering program. He was one of the original quants on Wall Street and had spent decades designing derivatives for Goldman Sachs, working alongside legends such as Fischer Black. Wilmott and Derman had become alarmed by the chaotic state of their profession and by the mind-boggling destruction it had helped bring about.

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

Consider this quotation from Time magazine of April 1994, cited by Peter Bernstein: “Prices of derivatives are not based on old-fashioned human hunches but on calculations designed and monitored by computer wizards using abstruse mathematical formulas . . . developed by so-called quants . . . ”2 Wizards, indeed. Even Emanuel Derman, one of the most famous of quants, feels compelled to assert that “[t]he Black-Scholes model tells us, almost miraculously, how to manufacture an option . . . ”3 (italics added). As the knowledge necessary to perform such feats is not a part of the regular secondary-school math curriculum, facility with derivatives requires a level of quantitative (hence “quant”) training and skill confined to the mathematical specialist.

In the paper in question, I showed that you could price options assuming the underlying stock followed a Poisson process. Later I showed with Michael Ong that this could be used to “correctly” price binary options using call spreads.16 JWPR007-Lindsey May 7, 2007 16:55 Neil Chriss 123 I wanted to get feedback on my paper and so I sent it around to various academics and also to Emanuel Derman, who was head of Goldman Sachs’ Quantitative Strategies Group, which was the leading group in derivatives pricing research at the time. Derman’s group was in charge of derivatives research and technology, and he was the most recognized figure in the industry at the time. One day, while sitting around IAS, Emanuel called me to tell me he had received my paper.

I taught a course of my own at Columbia in the mid 1980s and then started teaching as an adjunct at Yale. At Yale I had the pleasure over 15 years of coteaching with both my early mentor, Martin Shubik, and later my former Yale classmate but now well-known professor Will Goetzmann. In 2005, I returned to teach at Columbia at the encouragement of Emanuel Derman, along with Leon Metzger. In the early 1990s Jack Marshall and Bob Schwartz asked me to become involved in a professional society they were then organizing, the International Association of Financial Engineers. I was enthusiastic about being a part of that organization as I love everything about financial engineering.

Escape From Model Land: How Mathematical Models Can Lead Us Astray and What We Can Do About It
by Erica Thompson
Published 6 Dec 2022

I think there is a risk that the tree may not survive a hard pruning, but there is equally a risk of collapse if we allow it to continue being so unbalanced. Longer-term pruning and focused care will be needed to encourage the other branches to blossom. 7 Masters of the Universe I will remember that I didn’t make the world, and it doesn’t satisfy my equations. Emanuel Derman and Peter Wilmott, ‘The Financial Modelers’ Manifesto’ (2009) The use of models in economics, like other modelling endeavours, stems from a wish to control uncertainty about the future. Yet we remain highly uncertain, perhaps more uncertain than ever, about the outcome of modelled economic variables like stock prices or insurance losses over decision-relevant timescales: say, the next ten or twenty years.

Where the modeller endows their model with their own values, priorities and blind spots, the model then reflects those values, priorities and blind spots back, both in terms of how the system works and in terms of the kinds of interventions one could make. Stiglitz noted exactly this, that ‘our models do affect how we think’. Paul Wilmott and Emanuel Derman included in their Modeller’s Hippocratic Oath the following: ‘I will remember that I didn’t make the world, and it doesn’t satisfy my equations.’ While taking into account known uncertainties (via models), we also need to structure our thinking so that it is not completely blindsided by unknown or unknowable uncertainties.

Nerds on Wall Street: Math, Machines and Wired Markets
by David J. Leinweber
Published 31 Dec 2008

The other people writing for the book included some of the smartest kids on the block and some old friends, so I said yes on the spot. There are chapters by pillars of the quant world, authors of the standard texts, and writers of oft-cited papers. Others did interesting and rewarding things with technology and markets. Emanuel Derman, author of My Life as a Quant: Reflections on Physics and Finance ( John Wiley & Sons, 2004), made this point in the first line of his review for the Wall Street Journal: “By my reckoning, several of the 25 memoirists in How I Became a Quant are not true quants, and they are honest (or proud) enough to admit it.”2 xv xvi Introduction I am, no doubt, high on the list of poseurs, and I will be the first to admit it.

It has links in to all of these references, plus color and animated versions of the black & white screen grabs found in the book. The site will be updated often with new and topical items. Notes 1.

Steve Snider, who manages multibillion-dollar institutional portfolios at Fidelity, makes the point that “classical methods of data analysis assume that there is a stable process generating the data, so it is valid to attempt to deduce the underlying process from a selection of known observations. These new techniques don’t require that assumption, so they may be useful in especially noisy systems like stock forecasting.”5 That said, the dangers of rampant data mining using many of these approaches cannot be overemphasized (see Chapter 6, “Stupid Data Miner Tricks”). Emanuel Derman, former head of quantitative strategies at Goldman Sachs, described this over eagerness to blindly apply quantitative and computerized methods: The best quantitative finance brings real insight into the relation between value and uncertainty, and it approaches the quality of real science; the worst is a pseudoscientific hodgepodge of complex mathematics used with obscure justification.6 The Crackpot as Billionaire Not everyone who decides to burn CPU cycles on Wall Street ends up writing about lessons learned.

Extreme Money: Masters of the Universe and the Cult of Risk
by Satyajit Das
Published 14 Oct 2011

Sylvain Raines, an experienced quant, joked that quantitative finance was an oxymoron as “finance is quantitative by definition...this is like saying aerial flight or wet swimming.”11 Newly graduated financial experts applied simple “phenomenological toys” to markets. Most financial models are wrong, only the degree of error is in question. Differential equations, positive definite matrices or the desirable statistical properties of an estimator rarely determine the price of traded financial instruments. Goldman Sachs’ Emanuel Derman, a trained physicist, identified the difference: “In physics, a model is correct if it predicts the future trajectories of planets or the existence and properties of new planets.... In finance, you cannot easily prove a model right by such observations.” Derman ruefully concluded: “Trained economists have never seen a really first-class model.”12 Commenting on the required level of quantitative knowledge of people involved in financial markets, Derman once observed that Tour de France bicyclists did not need to know the laws of physics.

Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy
by Cathy O'Neil
Published 5 Sep 2016

How do we start to regulate the mathematical models that run more and more of our lives? I would suggest that the process begin with the modelers themselves. Like doctors, data scientists should pledge a Hippocratic Oath, one that focuses on the possible misuses and misinterpretations of their models. Following the market crash of 2008, two financial engineers, Emanuel Derman and Paul Wilmott, drew up such an oath. It reads: ~ I will remember that I didn’t make the world, and it doesn’t satisfy my equations. ~ Though I will use models boldly to estimate value, I will not be overly impressed by mathematics. ~ I will never sacrifice reality for elegance without explaining why I have done so

Makers and Takers: The Rise of Finance and the Fall of American Business
by Rana Foroohar
Published 16 May 2016

Markowitz’s quantitative finance methodology won him the Nobel Prize and became the basis of the first computerized arbitrage-trading program, which would eventually take over the markets. Today 70–80 percent of all trading is done by computers, much of it using flash programs designed to trade on fractional price changes over split-second time intervals, reducing the average holding period of a stock from about eight years in the 1960s to just four months by 2012.55 Emanuel Derman, a quantitative mathematician and physicist who pioneered some of those trading models at Goldman and now teaches financial engineering at Columbia, believes that the focus on mathematical economics in both finance and business education has gone way too far. Indeed, in 2012, he published a mea culpa for his own work in the twentieth-anniversary issue of the Journal of Derivatives.

The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution

They usually were tasked with building models to place values on complicated derivatives and mortgage products, analyze risk, and hedge, or protect, investment positions, activities that became known as forms of financial engineering. It took a little while for the finance industry to come up with a nickname for those designing and implementing these mathematical models. At first, they were called rocket scientists by those who assumed rocketry was the most advanced branch of science, says Emanuel Derman, who received a PhD in theoretical physics at Columbia University before joining a Wall Street firm. Over time, these specialists became known as quants, short for specialists in quantitative finance. For years, Derman recalls, senior managers at banks and investment firms, many of whom prided themselves on maintaining an ignorance of computers, employed the term as a pejorative.

Red-Blooded Risk: The Secret History of Wall Street
by Aaron Brown and Eric Kim
Published 10 Oct 2011

So I acknowledge here my debt to the dozens of people who provided slices of various characters’ history and attitudes. Many people read part or all of the manuscript and sent useful comments. Brandon Adams, Gustavo Bamberger, Bill Benter, John Bogle, Rick Bookstaber, Reuven Brenner, Eugene Christiansen, Emanuel Derman, Art Duquette, Dylan Evans, Doyne Farmer, Justin Fox, Kenneth French, Lisa Goldberg, James Grosjean, Ian Hacking, Michael Heneberry, Carey Hobbs, Craig Howe, James McManus, Michael Maubossin, Nick Maughan, Perry Mehrling, Robert Merton, Joe Nocera, John O’Brien, Deborah Pastor, Scott Patterson, William Poundstone, Kevin Rosema, Myron Scholes, James Stoner, Nassim Taleb, Edward Thorp, Whitney Tilson, James Ward, Paul Wilmott, and Bruce Zastera were particularly helpful.

If you like to study your quantitative finance through people, Espen Haug’s Derivatives Models on Models is an excellent choice. Also consider The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It by Scott Patterson, My Life as a Quant: Reflections on Physics and Finance by Emanuel Derman, Inside the House of Money: Top Hedge Fund Traders on Profiting in the Global Markets by Steven Drobny, and More Money Than God: Hedge Funds and the Making of a New Elite by Sebastian Mallaby. The Economic Function of Futures Markets by Jeffrey Williams remains after 20 years the only really good account of this subject.

Numbers Rule Your World: The Hidden Influence of Probability and Statistics on Everything You Do
by Kaiser Fung
Published 25 Jan 2010

Freakonomics is a notable exception, covering the applied research of the economics professor Steven Levitt. Two books in the finance area also fit the bill: in The Black Swan, Nassim Taleb harangues theoreticians of financial mathematics (and other related fields) on their failure in statistical thinking, while in My Life as a Quant, Emanuel Derman offers many valuable lessons for financial engineers, the most important of which is that modelers in the social sciences—unlike physicists—should not seek the truth. Daniel Kahneman summarized his Nobel-prize-winning research on the psychology of judgment, including the distinction between intuition and reasoning, in “Maps of Bounded Rationality: Psychology for Behavioral Economics,” published in American Economic Review.

The Rise of the Quants: Marschak, Sharpe, Black, Scholes and Merton
by Colin Read
Published 16 Jul 2012

While he had demonstrated that an options price depends on the underlying stock price mean and volatility, and the risk-free interest rate, the overall market for interest rates is much more multi-dimensional. The interest rate yield curve, which graphs rates against maturities, depends on many markets and instruments, each of which is subject to stochastic processes. His interest and collaboration with Emanuel Derman and Bill Toy resulted in a model of interest rates that was first used profitably by Goldman Sachs through the 1980s, but eventually entered the public domain when they published their work in the Financial Analysts Journal in 1990.2 Their model provided reasonable estimates for both the prices and volatilities of treasury bonds, and is still used today.

Data-Ism: The Revolution Transforming Decision Making, Consumer Behavior, and Almost Everything Else
by Steve Lohr
Published 10 Mar 2015

That is not necessarily a confidence-inspiring statement, given the lessons of the 2008 financial crisis. Quants didn’t cause the crisis, but they played their part. Their risk models proved myopic because they were too simple-minded, unable to take account of the rich, chaotic tapestry of behavior, especially in times of stress. Emanuel Derman, a physicist and former quant at Goldman Sachs, explained the perils of math models in finance, in his 2011 book, Models Behaving Badly. After coming to Wall Street in 1985, Derman soon came to believe that physics models could be successfully applied to finance and economics—a belief he later abandoned.

Swimming With Sharks: My Journey into the World of the Bankers
by Joris Luyendijk
Published 14 Sep 2015

A number of interviewees were struggling with this very question on a daily basis, and our conversations inevitably turned to complexity, and to the profound changes brought to the world of finance over the past decades by ‘quants’. In the middle office, quants build or manage the models their bank uses to calculate and possibly neutralise (‘hedge’) its risks. Drawn from academic backgrounds in maths, physics, chemistry and biology, these wizards invented the products that played a key role in the crash. Renowned quant Emanuel Derman typifies this new breed. After a few years as a physicist in academia and AT&T Bell Laboratories, Derman went to work for Goldman Sachs in 1985. In his bestselling autobiography My Life As a Quant he writes: ‘In physics you’re playing against God. In finance, you’re playing against God’s creatures.’

A Primer for the Mathematics of Financial Engineering
by Dan Stefanica
Published 4 Apr 2008

I learned a lot from working alongside my colleagues in the mathematics department and from many conversations with practitioners from the financial industry.. Special thanks are due to Elena Kosygina and Sherman Wong, as well as to my good friends Peter Carr and Salih Neftci. The title of the book was suggested by Emanuel Derman, and is more euphonious than any previously considered alternatives. Many students have looked over ever-changing versions of the book, and their help and encouragement were greatly appreciated. The knowledgeable comments and suggestions of Robert Spruill are reflected in the final version of the book, as are exercises suggested by Sudhanshu Pardasani.

Frequently Asked Questions in Quantitative Finance
by Paul Wilmott
Published 3 Jan 2007

The resulting volatility structure never matches actual volatility, and even if exotics are priced consistently it is not clear how to best hedge exotics with vanillas so as to minimize any model error. Such concerns seem to carry little weight, since the method is so ubiquitous. As so often happens in finance, once a technique becomes popular it is hard to go against the majority. There is job safety in numbers. See Emanuel Derman and Iraj Kani (1994), Bruno Dupire (1994) and Mark Rubinstein (1994). 1996 Avellaneda and Parás Marco Avellaneda and Antonio Parás were, together with Arnon Levy and Terry Lyons, the creators of the uncertain volatility model for option pricing. It was a great breakthrough for the rigorous, scientific side of finance theory, but the best was yet to come.

The Age of Stagnation: Why Perpetual Growth Is Unattainable and the Global Economy Is in Peril
by Satyajit Das
Published 9 Feb 2016

Reduced funding for military research, the cancellation of the Superconducting Super Collider project, and the scaling down of Bell Laboratories meant that a large number of scientists, some from Eastern Europe and China, drifted into finance. These POWs—physicists on Wall Street, a term coined by Goldman Sachs's Emanuel Derman—helped drive the trading of complex instruments, which were now an established part of the finance economy. These events and their influences were central to the continuation of postwar expansion. The period commencing in the 1990s became known as the Great Moderation, an era of strong economic growth, high production and employment, low inflation, reduced volatility in the business cycle, and self-adulation among politicians, central bankers, and academic economists.

Doing Data Science: Straight Talk From the Frontline

Published 8 Oct 2013

The next logical concept then is: models and algorithms are not only capable of predicting the future, but also of causing the future. That’s what we can look forward to, in the best of cases, and what we should fear in the worst. As an introduction to how to approach these issues ethically, let’s start with Emanuel Derman’s Hippocratic Oath of Modeling, which was made for financial modeling but fits perfectly into this framework: I will remember that I didn’t make the world and that it doesn’t satisfy my equations. Though I will use models boldly to estimate value, I will not be overly impressed by mathematics.

What Happened to Goldman Sachs: An Insider's Story of Organizational Drift and Its Unintended Consequences
by Steven G. Mandis
Published 9 Sep 2013

Interviews confirmed the level of dissonance at Goldman, even as a publicly traded firm, in discussing and understanding that the output of the models was and is unique to Goldman, which meant the firm was not as dependent on the models as were other firms, and that, combined with what sociologists call a “heterarchical structure” (less hierarchy in the chain of command than in many firms) and the trading experience of its top executives, gave Goldman an edge.8 The more intense scrutiny of the models and risk factors led Goldman’s top executives to pick up on market signals that other firms’ executives missed.9 As Emanuel Derman, the former head of the quantitative risk strategies group at Goldman and now a professor at Columbia, wrote, at Goldman, “Even if you insist on representing risk with a single number, VaR isn’t the best one … As a result, though we [Goldman] used VaR, we didn’t make it our religion.”10 (Meanwhile, at other firms, measures like “VaR [value at risk] … became institutionalized,” as the New York Times’ Joe Nocera put it.

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

For instance, we consider a stock’s price-to-earnings ratio, not its enterprise value-to-earnings ratio because the latter would look bad for a leveraged firm just because the interest payments reduce the earnings. Hence, with enterprise value in the numerator, the denominator should have earnings before interest expenses. ___________________ 1 Quantitative traders are close cousins to, but perform different roles than, the “sell-side quants” described in Emanuel Derman’s interesting autobiography My Life as a Quant (2004). Sell-side quants provide analytical tools that are helpful for hedging, risk management, discretionary traders, clients, and other purposes. In contrast, quantitative traders work on the “buy-side” and build models that are used directly as a tool for systematic trading. 2 See Damodaran (2012) for an extensive description of equity valuation and financial statement analysis. 3 To see this result, first note that Then change index on the first book value and make the appropriate adjustments to arrive at which gives the residual income model.

The influential economist Irving Fisher wrote his doctoral dissertation under the supervision of a physicist, and later helped build a machine with levers and pumps to illustrate how an economy works. Paul Samuelson applied the mathematical principles of thermodynamics to economics. On the finance side, Emanuel Derman was a physicist who became a financier and played a central role in developing the models for derivatives. While valuable tools for understanding economic behavior, mathematical models were also like lenses that filtered out certain aspects of human nature. They depended on the notion that people are basically regular and predictable.

The Concepts and Practice of Mathematical Finance
by Mark S. Joshi
Published 24 Dec 2003

When pricing an exotic option we should be careful to examine what features of the model it is particularly sensitive to. 18.8 Further reading Jim Gatheral's book, [58], is the best reference currently available on the dynamics of the volatility surface. Cont and Fonseca, [40], carried out a principal components analysis of the volatility surface for index options in S&P and FTSE. They have many interesting results including that relative movements of implied volatilities have little correlation with the underlying. Emanuel Derman carried out an analysis of how changes in spot related to changes in skew for the S&P 500 and identified differing regimes over time, [46]. Other papers applying the same methodologies in different contexts are [1] and [117]. See also [12], [83] and [84] for further discussion of how option price movements are affected by spot movements in the real world.
