Abstract

Despite the recent market upheavals, the OTC derivatives markets continue to comprise one of the largest components of the financial markets, with an overall outstanding notional of $547 trillion in December 2008, 70% of which are in interest rate derivatives. As of June 2009, this grew to $605 trillion. And in spite of market contractions, gross values in the OTC markets are up. From June 2008 to December 2008, OTC gross market value increased 60%, from $20 trillion to $32 trillion (Bank for International Settlements, June 2009). Interest rate derivatives’ gross market value doubled from $9 trillion to $18 trillion.

Prompted by the desire to weather or even reduce market turmoil, regulations, accounting practices and investment practices have been under reevaluation. In particular, approaches for analyzing and mitigating counterparty risk have garnered renewed interest. Regulators have been advocating greater usage of clearing houses. Accounting boards have been refining and codifying fair market valuation, placing additional emphasis on careful consideration of counterparty risk. The IASB has even issued a request for comment on counterparty risk calculation methodologies. And investors and traders have been trying to better factor some notion of counterparty risk into their trading and risk management practices.

Here we will investigate the notion of counterparty risk and the associated counterparty valuation adjustment (CVA) in the fixed income markets. We will outline the CVA calculation, detail the underlying model assumptions, give examples of the calculation and discuss the impact the CVA has in the value of these instruments, relating CVA calculations to CDS & CCDS (contingent CDS).

Abstract

Portfolio optimization is going through a revolution with the recent algorithmic advances in conic optimization. By generalizing quadratic optimization, conic optimization allows new ways of modeling and solving a broader class of risk optimization problems efficiently. In this talk, we will give a brief introduction to conic optimization and describe applications in factor modeling, portfolio optimization, transaction cost modeling, value-at-risk minimization. We will go over new techniques for solving hard mixed-integer conic optimization problems. Finally, we will introduce the recently launched Bloomberg Portfolio Optimizer built on top of this new technology.

Speaker

Abstract

Can Tail Risk Be Hedged?

Tail risk hedge is a catchall for strategies that are contractual (derivative-based), macroeconomic or statistical. It also applies to a wide range of structured products and funds that are available for purchase. We discuss the principles underlying contractual tail risk hedges and we provide an empirical assessment of the value they offer.

Thalesian Seminar (London) — Dr. Iain Clark — Foreign Currency Options: Deltas, Market Conventions and Volatility Smiles

Abstract

Foreign currency as an asset class is noted by the presence of not one but two possible numeraires: the so-called domestic and foreign currencies. Since market participants can regard the risk free money market account in either of these currencies as their natural numeraire, the risk-neutral option pricing technique can proceed in one of two ways: either we price options on the foreign currency from the domestic investor’s point of view, or we price options on the domestic currency from the foreign investor’s point of view.

In this talk we show using the standard Black-Scholes model that the two approaches are mathematically equivalent in price terms, which is reassuring. It means that investors in both domestic and foreign economies will naturally agree on the model price. However, unless volatilities are negligible they will absolutely not agree on the risk numbers, in particular the delta (which can be either spot delta or forward delta). This is of particular importance in foreign currency options, which naturally have volatility surfaces described using strangles and risk reversals expressed in terms of deltas -- most commonly 25- and 10-delta. It turns out that the discrepancy is directly related to which currency the premium for the option is paid in, a cashflow which will naturally be regarded as risky for one investor but riskless for the other.

We conclude by giving an overview of the way in which FX volatility surfaces are constructed, taking into account the ATM backbone, single-vol broker strangles and risk reversals – where we see the surprising feature that a convex smile can have a small and even negative broker strangle if the skew is large enough.

Abstract

The Markowitz mean-variance framework provides the foundation for modern portfolio theory. One problem with this approach, however, is that sample covariance matrices tend to underestimate the true risk of optimized portfolios. In this presentation, we show that the biases of optimized portfolios are closely related to biases in eigenfactor portfolios. We present a methodology for estimating the biases in eigenfactor volatilities, and for adjusting the covariance matrix to remove such biases. We show that by removing the biases of the eigenfactors, we effectively remove the biases of optimized portfolios as well. We also examine the out-of-sample performance of optimized portfolios. Relative to the conventional sample covariance matrices, we find that the eigen-adjusted covariance matrices produce portfolios with lower out-of-sample volatilities.

Abstract

The presentation reviews interest-rate modeling since its advent in the mid 70s, with particular focus on fixed-income derivatives and their valuation. We highlight the crucial role played by practitioners in the evolution of modeling to the present day. As we argue, the major theoretical advances were incited by traders needs and insistence on model compatibility with liquid instruments. The Gaussian, BDT, HJM, and Libor Market Models are discussed in some detail and many other models remarked on. We conclude with some outstanding issues of great practical importance that still defy a satisfactory theoretical solution.

Thalesian Seminar (London) — Dr. Boryana Racheva-Iotova — Myths and Realities — Why Many Investment Managers Are Hesitant to Implement Fat-tailed Risk Models

Abstract

It's fact that "Black Swans" and "Fat-tails" are among the key buzz words since late 2008 and even more so recently. It's also fact that there is hesitation for many on adopting risk and portfolio management approaches that better capture the tail risk. We explore the question “Why?” Clearly people in different roles from Quants to CEO's have different views and thought processes. Some are very clear and well grounded but others are closer to myths. This talk will try to demystify what is behind those concerns and provide both quantitative views and a common-sense inventory on how these stand up as we head into 2012:

  • Are Fat-tailed approaches always more conservative and do they lead to missed opportunities?
  • Are Fat-tailed models technically unmanageable – model fitting, infinite variance, stability, can’t price derivatives?
  • There are so many approaches proposed recently - how to distinguish which are sound and reliable? - "I have seen bizarre results..."
  • The value versus complexity isn’t worth it... right?
  • Does it really matter over the long-term?
  • Is the practical system implementation harder?
  • How to ensure acceptance within the Firm and explain to the board and investors?!...

Abstract

Financial models play a critical role in the investment process, but we sometimes forget that they are just that: models. There is always a gap between the model and the true behavior of the markets. In addition to the uncertainty captured by a model, “first order risk”, there is additional risk due to uncertainty of the model itself, “second order risk”. We show that this additional source of risk is often much larger than would be expected, and we can begin to forecast this risk like more traditional sources of uncertainty.

Speaker

Peter Shepard is a Vice President and Senior Researcher at MSCI, where he works in multi-asset class research. He led development of the new Barra Integrated Model (BIM301), spanning global stocks, bonds, commodities, currencies, hedge funds, private real estate, and equity volatility futures. He was an architect of the Barra Global Equity Model (GEM2), and has done research in portfolio construction. Prior to joining MSCI, he worked in fixed income risk modeling in the quantitative research group at Thomson Financial.

Abstract

Option pricing libraries developed in-house by financial institutions share many features. Specifically, most of them are Excel add-ins written in C++ that give to users the ability of instantiating objects (e.g. volatility surfaces, models, instruments, etc.) on the spreadsheet. The objects are stored in a repository and handles to these objects are returned to the spreadsheet, allowing the users to call their methods.

KeyValue is a library that helps the development of such add-ins. Additionally, the library is cross-platform and creates OpenOffice and LibreOffice extensions that work on Windows and GNU/Linux systems.

The library is named after its interface where function parameters are passed through key-value pairs in contrast to the standard positional interfaces of Excel, LibreOffice and OpenOffice. The way that pricing spreadsheets are designed makes this interface very convenient.

KeyValue is flexible and can be used in other areas. This talk is an introduction specially tailored for quants and quant-devs.

Speaker

Cassio Neri completed his Ph.D. in Applied Mathematics at University of Paris-Dauphine in 2002 advised by Prof. Pierre-Louis Lions.

After a few years lecturing Applied Mathematics at the Federal University of Rio de Janeiro, he moved to London in 2006 and became a quantitative analyst. Before joining the FX Quantitative Research Team of Lloyds Bank Corporate Markets, he worked at Dresdner Kleinwort and Commerzbank.

Cassio's research interests are applications of Statistical Mechanics and Entropic Methods to finance. He has published articles in journals on mathematics, financial mathematics and programming.

Abstract

For ship and aircraft financing long term roll-over loans are often equipped with the right to change the currency every quarter at spot. The loan taker then pays LIBOR of the respective currency plus a pre-determined constant sales margin. If the capital outstanding exceeds 105% calculated in the original currency, the amortization is required to the level of 105% of the original currency. By clever currency management the loan taker can amortize the loan faster and terminate the loan early. Essentially the loan taker owns a series of options on the cross currency basis spread with unknown notional amounts. We determine the key drivers of risk, an approach to valuation and hedging, taking into consideration the regulatory constraints of a required long term funding.

Key words: currency option, basis spread, cross currency swap, roll-over loan, derivatives valuation

This event will be held in conjunction with the GARP San Francisco Chapter meetings. GARP members can alternatively register for this event at http:/www.garp.com

Abstract

Quantitative finance relies on a number of assumptions about the behavior of markets. The degree to which these assumptions approximate the reality may or may not lead to accurate analysis and forecasting. This talk will examine these assumptions in an historical context and with a view as to how to make them better, or at least less dangerous when mis-handled.

Abstract

We ask if the business model used by banks to price and hedge complex derivatives is broken. Answering our own question in the affirmative, we propose simple-to-implement fixes which are based on more fundamental economic analysis and on banks holding reserves against market imperfections and model risks.

Speaker

John Crosby gained a first class honours degree in Applied Mathematics and Theoretical Physics at Girton College, Cambridge University before going on to study Electrical Engineering at University College, Oxford University. He began his career by trading fx options. He then moved to Monis (formerly London Business School Financial Software) where he researched and wrote their pricing libraries for a very wide range of exotic options as well as co-writing their three-factor Convertible bond model, which captured stochastic equity prices, interest-rates and default risk. He has then worked at First Chicago, Barclays Capital and Lloyds TSB Financial Markets where he has been responsible for developing advanced models for pricing and risk-managing a wide-range of complex derivatives. John is best known for publishing a number of papers on the subject of pricing commodity derivatives using a multi-factor jump-diffusion model and for being a co-author of the Carr-Crosby fx options model.

John is a visiting Professor of Finance in the Centre for Economic and Financial Studies in the Department of Economics at Glasgow University.

John is also an invited lecturer on the M.Sc. course in Mathematical Finance in the Mathematical Institute at Oxford University (link here).

Outside of mathematical finance and derivatives research, his main interests are sport (he is a keen runner and cyclist and regularly goes to the gym) and history. He is also a reasonably proficient speaker of Russian.

Abstract

"Cubature on Wiener space" is a numerical method for the weak approximation of SDEs. After an introduction to this method we present some cases when the method is computationally expensive, and highlight some techniques that improve the tractability. In particular, we adapt the Multilevel Monte-Carlo framework and extend the Milstein-scheme based version of Mike Giles to higher dimensional and higher degree cases.

Speaker

Lajos Gergely Gyurko obtained a DPhil in Mathematics from the Mathematical Institute, University of Oxford. After graduating he joined the institute as a Departmental Lecturer. Beyond lecturing numerical methods, Greg is the course director of the Mathematical and Computational Finance MSc and faculty member of the Oxford-Man Institute of Quantitative Finance. Greg's research interests are Rough Paths Theory and its applications in Computational Finance.

Abstract

Basel III and the Dodd-Frank Act are inducing a shift in counterparty credit risk management and trading practices. To address the multiple challenges, we developed a high performance single node engine for global market simulations and for the modeling of global portfolios of netting sets.

Our engine's performance as a CVA calculator proved to be vastly superior to that of traditional grid farm implementations. Moreover, we found several other more advanced applications which are nearly out of reach of grid computing, including

  • Fully calibrated, arbitrage free, dynamic modeling of all credit and market factors under the risk neutral measure;
  • Efficient valuation of CVA volatility, as required under the advanced Basel III framework;
  • Pricing of margin revolvers, i.e. revolving lines of credit attached to cross-product netting sets for cleared portfolios; and
  • Securitization of portfolios of margin revolvers.

In the talk we elaborate on the changing regulatory environment, the software architecture we implemented and the specialist hardware configurations we use and contributed to design.

Abstract

In this talk, we review various models of market impact. We use variational calculus to derive optimal execution strategies, and show that in many conventional models, static strategies are dynamically optimal. We then present a model in which the optimal strategy does depend on the stock price and derive an explicit closed-form solution for this strategy by solving the HJB equation. We conclude by exploring the sensitivity of expected cost in this model to the execution strategy. This is joint work with Alexander Schied.

Abstract

Complex derivatives are not obscure constructs of a twisted mind, but have developed due to client interest under certain economic environments. Derivatives are not homogenous and whilst they have not always been put to proper use, a better understanding will help identify suitable opportunities to harness them. This talk will present some common themes behind the construction of various derivatives in equities, foreign exchange and interest rates. This will be discussed in the context of the economic environment, which is crucial to understanding the impetus for their development. Whilst times may have changed and so may the flavours of derivatives, the considerations behind various derivatives features will always remain relevant.

Speaker

Chia Chiang Tan is currently a Director within DB Analytics at Deutsche Bank, and an Honorary Lecturer with the Mathematics Department at University College London. He has previously held positions at Dresdner Kleinwort, Barclays Capital and CIBC. His work has spanned equities, foreign exchange and interest rates, giving him a bird's eye view of their common themes and individual peculiarities. Chia has an undergraduate degree in Mathematics from University College London and a Master of Mathematical Finance from University of Toronto.

Abstract

Complexity Science and Statistical Mechanics are powerful transdisciplinary methodologies that allow a precise mathematical study of systems level emergent phenomena, which are caused by the multitude of interactions taking place at the component level. Inspired by more than a decades experience in modeling evolutionary ecology (including intermittent mass extinctions) I’ll discuss how a holistic network approach can be applied to market and finance and how this may inform our understanding of why and how major upheavals occur.

The relevance of such an approach was recently stress by Andrew G Haldane, Executive Director, Financial Stability, Bank of England who said: "...considers the financial system as a complex adaptive system. It applies some of the lessons from other network disciplines – such as ecology, epidemiology, biology and engineering – to the financial sphere. Peering through the network lens, it provides a rather different account of the structural vulnerabilities that built-up in the financial system over the past decade and suggests ways of improving its robustness in the period ahead."

I’ll discuss the specific framework our research group has developed and how fairly simple models, with an emphasis on the essential collective network effects and emergent behaviour, can be constructed and what kind of questions this approach may be able to address.

Speaker

Henrik Jeldtoft Jensen is a Professor of Mathematical Physics in the Department of Mathematics at Imperial College London. He leads the research programme in Complexity and Networks in the Institute for Mathematical Sciences at Imperial. His research on complex systems revolves around how statistical mechanics can describe and explain emergent phenomena. His research activities include long-time macroevolution, EEG signatures of musical creativity and complexity measures of the strongly correlated activity spanning the brain as extracted from fMRI data.

He has a long time interest in the relation between mathematics and scientific enquiry on one side and the deliberation of the arts and philosophy on the other.

Abstract

Although the explosive growth in the trading and complexity of credit derivative instruments was checked by the credit crunch, and the credit default swap spreads have only just returned to their pre-2007 levels, the post-crunch drive for more accurate and robust models has further increased the computational overhead. This has in turn led to massive growth in data center compute capacity, and consequently power and cooling requirements. Maxeler applies a vertical acceleration process which optimizes across levels of abstraction by restructuring the software and building the computer system (rack, node, card and gate level) based on the source code rather than creating the program based on the available hardware. Our results with JP Morgan show that valueing bespoke tranches of collateralized default obligations (CDOs) and interest rate derivatives on Maxeler accelerated systems is over 30 times faster per cubic foot and per Watt than solutions using standard multi-core Intel Xeon processors.

Speaker

Michael J. Flynn, Chairman of Maxeler Technologies, Professor of Electrical Engineering at Stanford University, is best-known for the [SIMD, SISD, MISD, MIMD] classification and the first detailed discussion of super scalar design.

Abstract

In this talk we provide evidence that financial option markets for equity indices give rise to non-trivial dependency structures between its constituents. Thus, if the individual constituent distributions of an equity index are inferred from the single-stock option markets and combined via a Gaussian copula, for example, one fails to explain the steepness of the observed volatility skew of the index. Intuitively, index option prices are encoding higher correlations in cases where the option is particularly sensitive to stress scenarios of the market. As a result, more complex dependency structures emerge than the ones described by Gaussian copulas or (state-independent) linear correlation structures. In this paper we "decode" the index option market and extract this correlation information in order to extend the multi-asset version of Dupire's "local volatility" model by making correlations a dynamic variable of the market. A "local correlation" model (LCM) is introduced for the pricing of multi-asset derivatives. We show how consistency with the index volatility data can be achieved by construction. LCM achieves consistency with both the constituent- and index option markets by construction while preserving the efficiency and easy implementation of Dupire's model.

Abstract

This talk is a introduction to the author’s forthcoming book Foreign Exchange Option Pricing: A Practitioner’s Guide. FX options have recently enjoyed a resurgence in popularity and this talk presents some of the theory and the numerical toolkit required for developing a practical quant library for FX option pricing. First, I describe the standard market conventions encountered in FX and how they are used when constructing implied volatility surfaces. I then introduce standard short-dated FX models such as local vol, stochastic vol and LSV and briefly describe the calibration of these to the market. Once calibrated models are available, FX instruments such as first generation exotics (binary and barrier options) can be priced using numerical methods such as PDEs and Monte Carlo. Finally we describe the auxiliary state variables approach, which opens up second generation exotics such as lookbacks, average rate options and realised volatility products and admits a nice visual interpretation when considered on stacked PDE meshes.

Speaker

Iain Clark has over 13 years experience as a front office quant. He is Head of FX Quantitative Analysis at Unicredit. He has previously worked at Standard Bank as Head of FX and Commodities Quantitative Analysis, Dresdner Kleinwort, Lehman Brothers, BNP Paribas and JP Morgan.

OpenCL stands for Open Computing Language, a powerful open standard backed by large companies like NVIDIA, AMD, IBM, Apple, Qualcomm and many others. The language supports a sustainable programming model for heterogeneous computing, allowing code to be executed on a range of accelerator platforms such as many-core CPUs, GPUs and also on low-power ARM-based devices and in the future possibly FPGAs too.

Financial algorithms implemented in legacy codes cannot be automatically converted to optimised OpenCL code. The specific algorithm-knowledge, developed by the quant, needs to be communicated to a software architect with very specific and different knowledge. This translation from one world to the other is an infamous IT-obstacle and has been a strong motivator for the development of new software technologies and solution approaches. This is the context in which we evaluate the potential benefits and the pitfalls of OpenCL and discuss some of the latest research and development projects.

During the talk we explore concrete examples of how this conversion is done in the CPU-world, from Excel-macros to compiled Matlab-code. Then we will walk through different conversion approaches in the massively parallel computing world, culminating in an OpenCL based solution approach that can serve to guide migration projects in quantitative finance.

Speaker

Vincent Hindriksen is the owner of StreamComputing, a Netherlands based start-up specialising in accelerating computations using OpenCL. Since graduating with a Master's degree in computer science, Vincent has worked on several projects where he has added value by focusing on the usability and performance. Before launching his company, he worked for a Dutch pension fund APG, where he accelerated a data-acquisition process by 10x. Vincent will publish his first online book on OpenCL later this year.

Abstract

This talk is NOT intended for those of a musical bent, but for those who might be tempted to gamble in the hope of making a small fortune. Of course the easiest way to do this is to start with a large fortune... However, this talk IS intended to provide some instruction in the ways in which gambling odds may be slanted unfairly to the profit of the card sharp or dice mechanic, at the considerable expense of the innocent and or unwary.

Speaker

Frank Berkshire is the Director of Undergraduate Studies in the Department of Mathematics of Imperial College London.

In addition to his responsibilities for the mathematical course structure and content, he has for many years been fighting a (largely losing) battle against the rise in academic bureaucracy — subject reviews, subject benchmarks, and so on. An imminent challenge is to confront the European Bachelor/Masters structures post-Bologna, while reconciling a role as consultant for the Qualifications and Curriculum Authority on Secondary level assessments — most recently through Chairing the 5-Year Review of Standards over Time for GCSE/AS/A Level Mathematics (2005).

His long term research interests include: fluid mechanics; waves in fluids with applications to oceanic and atmospheric flows; nonlinear partial differential equations, wave focusing and solitons; dynamics; sporting and biological mechanics; statistical aspects of dynamical systems; game theory; gambling; dice; billiards and chaos.

With Professor Tom Kibble he is author of Classical Mechanics (5th Edition 2004 Imperial College/World Scientific).

Abstract

Many developers of financial software have now used (or at least heard of) GPUs, but fewer have heard of FPGAs, let alone tried to use one. Despite having been on the scene for longer, FPGAs have been replaced by GPUs as the acceleration technology of choice, mainly due to ease-of-use provided by CUDA and a coherent marketing plan. However, FPGAs are still a competitive technology, providing similar acceleration levels to GPUs, with only a tenth the power and cooling requirements.

This talk will outline recent research directions in FPGAs for financial computing, and give some insight into the things that FPGAs are really good at, as well as identifying situations where they are probably not the best choice and GPUs or CPUs are more appropriate.

Speaker

David Thomas is a post-doctoral research associate in the Department of Computing in Imperial College, working mainly with FPGAs, as part of the Custom Computing group.

His two main research interests are random number generators for FPGAs, and also financial computing using FPGAs.

Abstract

The Black-Scholes model, due to the assumption of constant volatility, fails to described observed smiles and skews in the market. Two common methods to incorporate smiles and skews into asset price models are state dependent volatility (also known as local volatility) and stochastic volatility (jump-diffusions and Levy processes are also used, but perhaps not quite so ubiquitously in the market).

In this talk, I will give an introduction to the mathematics behind local and stochastic volatility models. The construction of local volatility, first noted by Dupire (1993), relies upon an earlier result from Gyongy (1996) where it was asked: "is it possible to construct a diffusion which matches the marginal distributions at all known time points in the future?". If we know the implied volatilities and thereby the prices of all traded options at a time t, we know the marginal distribution from the Breeden-Litzenberg (1978) result, and can work with that.

Stochastic volatility, e.g. Heston (1993) et al., models a second untradeable factor which feeds into the diffusion for the tradeable asset. While requiring two factors, this is easily numerically tractable. Furthermore, there are numerical techniques which enable European options to be priced using characteristic functions and Fourier integration, which are useful for fast calibration to Europeans. Path dependent options can be priced using 2D Monte Carlo or PDE techiques, where the diffusion of the traded asset depends on the level of the untradeable factor.

For local and stochastic volatility models, the rate of diffusion of the traded asset depends on (a) the level of the traded asset price, and (b) the level of the untradeable factor, respectively. Mixed local-stochastic volatility models such as in Jex, Henderson and Wang (1999) and Ren Madan and Qian (2007) allow the diffusion of the tradeable asset to depend on both factors. A full discussion of mixed local-stochastic volatility models is beyond the scope of this talk but a brief introduction is given, with particular reference to the mathematics described in this talk.

Abstract

Monte Carlo simulation is one of the most important numerical methods in financial derivative pricing and risk management. Due to the increasing sophistication of exotic derivative models, Monte Carlo becomes the method of choice for numerical implementations because of its flexibility in high-dimensional problems. However, the method of discretization of the underlying stochastic differential equation (SDE) has a significant effect on convergence. In addition the choice of computing platform and the exploitation of parallelism offer further efficiency gains. We consider here the effect of higher order discretization methods together with the possibilities opened up by the advent of programmable graphics processing units (GPUs) on the overall performance of Monte Carlo and quasi-Monte Carlo methods.

Speaker

Robert Tong received a PhD from the University of Bristol (UK) in the area of applied mathematics and scientific computing, following a first degree in mathematics. His research project was prompted by the need to improve the modeling and design of coastal structures after a major failure.

He followed this with the post of Research Fellow in Applied Mathematics at the University of Birmingham, where his focus was on the role of numerical software and mathematical modeling in the context of the failure of structures due to extreme events.

His interest in numerical software led naturally to his joining NAG to work on the development of their libraries. While there he has worked on data approximation methods, including wavelets and radial basis functions, in addition to applications in finance.

Kai Zhang is pursuing a PhD in mathematical finance with Dr. Nick Webber from Warwick Business School. His research focuses on novel derivative pricing methods and efficient model implementations.

He joined NAG as an intern at the end the second year of his study. His duties are supplying Monte Carlo simulation components, developing example financial applications, writing technical reports for clients and collaborating with leading researchers and practitioners to incorporate new methods in the library.

Abstract

Suppose that one can observe European option prices at discrete strikes and at one or more maturities. Here we assume that the risk-neutral process for the underlying futures price is a pure jump Markov martingale operating in continuous time with a continuous state space. When the given option prices are arbitrage free and on a regular grid, we show how to construct a piecewise time and space-homogeneous process that meets them. Our construction leads to partial differential difference equations (PDDE's), which permit both explicit calibration and fast numerical valuation. The construction marries ideas from local volatility and variance gamma and is christened the local variance gamma model.

Speaker

Abstract

Despite its popularity, VaR lacks some desirable theoretical properties.

Firstly, VaR is known to be a non-convex risk measure. As a result, VaR optimization problems usually are computationally intractable. In fact, they belong to the class of chance-constrained stochastic programs, which are notoriously difficult to solve. Secondly, VaR fails to satisfy the subadditivity property of coherent risk measures. Thus, the VaR of a portfolio can exceed the weighted sum of the VaRs of its constituents. In other words, VaR may penalize diversification. Finally, the computation of VaR requires precise knowledge of the joint probability distribution of the asset returns, which is rarely available in practice.

Usually the investor has some distributional information about the asset returns, such as the first- and second-order moments. A common mistake is then to assume that the asset returns are normally distributed. This "Normal-VaR" approximation is appealing as it is a convex function (at least for most threshold values) and is therefore amenable to convex optimization techniques. However, the normality assumption can be extremely dangerous as it rarely holds in reality. When the true distribution is non Gaussian the implications can be disastrous for Normal-VaR optimized portfolios since the risk may be severely underestimated (Black Swans).

Recently, we developed new Worst-Case VaR models for derivative portfolios. These models assume that only certain elements of information are known about the distribution of the underlying asset returns (such as means, covariance matrix, support, etc) but are otherwise unknown. We take into account the set of all distributions that match the known elements of information about the distribution (even those with high skewness, kurtosis, etc). The Worst-Case VaR is then computed as the VaR under the worst-case probability distribution in this set. This method essentially immunizes us against distributional model risk by optimizing the portfolio over the (possibly infinite) set of matching distributions. As more information is provided about the distribution, Worst-Case VaR becomes less conservative.

It turns out that these worst-case portfolio optimization models can be solved using extremely efficient convex optimization algorithms. Worst-Case VaR is a convex risk measure and is therefore also subadditive. Our numerical out-of-sample Worst-Case VaR optimization backtests are very encouraging.

Speaker

Steve Zymler is a PhD student at the Optimization Group of Imperial College London. His research focusses on decision making under uncertainty. In particular, he investigates novel robust risk models which do not make strong assumptions about the probability distributions of the underlying random variables. Steve is also actively involved in developing software solutions that are able to compute as well as minimize the risk of large scale derivative portfolios. These software packages can be used for automated trading and risk management.

Prior to commencing his PhD, Steve graduated from Imperial College with a first class honours master's degree in Computer Science. Steve has received numerous awards, such as the Microsoft Prize for best master thesis (2006), and was voted amongst the top three students at the British SET Awards (Science, Engineering & Technology Student of the Year 2006). He was also a finalist at British Computing Society (BCS) national programming competition (2003) and the Flemish Mathematics Olympiad (2002).

Abstract

The PDE approach to Option Pricing under jump-diffusion processes (useful for American style contracts) leads to the need to solve numerically a partial integro-differential equation. Merton’s jump-diffusion model is not too hard but probability distributions such as Variance-Gamma and CGMY produce singularities within the integrals and require more care. A number of approaches can be used and this talk describes in detail the use of finite differences with a coordinate transformation. These transformations permit a highly refined mesh in localised regions of interest and, since they have a uniform mesh in the transformed coordinate, allow the use of Richardson extrapolation. Continuously sampled Asian options have a nice structure with this approach and can be solved accurately using a semi-Lagrange time integration approach that should speed up efficiently on parallel hardware.

Abstract

In the last decade, a new class of numerical methods for approximating distributions of solutions of SDEs have been introduced by Kusuoka, Lyons, Ninomiya and Victoir. These methods are based on the work of Kusuoka and Stroock who established refined gradient upper bounds for the associated semigroup using Malliavin Calculus techiniques. In this talk, I will present an application of these methods to the numerical solution of Backward SDEs together with applications to option pricing. The talk is based on joint work with S. Ghazali and K. Manolarakis.

Speaker

Dan Crisan is a Reader in Mathematics at Imperial College London. His expertise lies in the area of Stochastic Analysis with applications in Engineering and Finance. His current research is on developing high-order numerical algorithms for solving stochastic differential equations, approximating schemes for backward SDEs and particle methods for nonlinear filtering. His book, Fundamentals of Stochastic Filtering appeared at Springer Verlag at the begining of the year and he is currently involved in editing an advanced handbook on Nonlinear Filtering to be published by the Oxford University Press. Dr. Crisan is a member of the editorial board of the Journal of Mathematics and Computation. He is also actively involved in teaching. Among numerous other courses, he has taught stochastic filtering, numerical stochastics, and measure-valued processes at Imperial College; applied probability, and stochastic calculus and applications at Cambridge University.

Abstract

Following an idea of Piterbarg, we explain how Markovian projection can be used to derive an effective pricing model with smile for European options on a basket. The basket will contain n currencies, each admitting smile and calibrated to the Heston model. This implies that the process for the basket has 2n underlying Brownian motions. Markovian projection generates an effective model driven only by two Brownian motions (a shifted Heston model) representing the basket.

Along the course we give some introduction to the Heston model and develop a calibration method for the correlation matrix between the Heston models of various currencies.

Speaker

Rene Reinbacher holds a Masters degree in Mathematics and a PhD in Physics from the University of Pennsylvania. He was a Postdoctoral Researcher at Rutgers University and Harvard University.

Rene's academic interests include string theory and algebraic geometry. In particular, he was working on the application of algebraic-geometric methods in string theory to study the existence and properties of solutions to nonlinear PDE’s on compact spaces via Kobayashi correspondence, and the numerical methods for explicit construction of these solutions. He used recent theoretical results and numerical methods in C++ to obtain the first known solutions of Ricci flat metrics and Hermitian Yang-Mills equations on compact Calabi-Yau threefolds.

Rene has worked at Lehman Brothers and Barclays Capital as an FX and DCRM front office quant. He is currently working for Barclays Capital.

Abstract

Using constraints in portfolio construction causes deviations from the classical mean-variance portfolio, which are referred to as unrealized alpha, opportunity costs, or implementation inefficiency. Various measures like the transfer coefficient attempt to quantify such effects.

Axioma developed a novel methodology — called Constraint Attribution — to consistently allocate these deviations to individual constraints. Besides identifying the largest obstacles for increasing implementation efficiency, such attribution gives portfolio managers deeper insights into and thus greater control over their portfolio construction process. This talk introduces the methodology and discusses results for exemplary strategies.

Speaker

Adrian Zymolka is Senior Director of Client Services for Axioma, now based in New York after having spent some years in Axioma's London office.


He holds a diploma in Mathematics from the Philipps University Marburg and a Ph.D. in Mathematics from the Technical University in Berlin. During his Ph.D. time at the Zuse Institute Berlin (ZIB), Adrian was a research assistant in the Optimization department headed by Prof. Martin Grötschel. He developed optimization methods for highly complex problems in the area of telecommunication network design and was leading and participating in various industrial projects. In 2006, he joined atesio, a ZIB spin-off company, where he worked as optimization consultant and developer. Since joining Axioma in 2007, Adrian helps users of Axioma's optimization technology to model portfolio strategies tailored to their goals and needs.

Abstract

Recognizing that robust decision making is vital in risk management, we provide concepts for computing the best decision in view of the worst-case scenario. The main tool used is minimax, which ensures robust policies with guaranteed optimal performance that will improve further if the worst case is not realized.

Critically, worst-case design addresses not only Armageddon-type uncertainty. Indeed, the determination of the worst case becomes nontrivial when faced with numerous — possibly infinite — and reasonably likely rival scenarios. Optimality does not depend on any single scenario but on all the scenarios under consideration. Worst-case optimal decisions provide guaranteed optimal performance for systems operating within the specified scenario range characterising the uncertainty.

The noninferiority of minimax solutions — which also offer the possibility of multiple maxima — ensures this optimality. Worst-case design is not intended to necessarily replace expected value optimization when the underlying uncertainty is stochastic. However, wise decision making requires the justification of policies based on expected value optimization in view of the worst-case scenario. Conversely, the cost of the assured performance provided by robust worst-case decision making needs to be evaluated relative to optimal expected values.

Robustness is thus intended to relax the inherent inaccuracy of forecasts. This applies to single as well as multi-period portfolio decision problems. We begin by introducing a generalisation of the standard Markowitz framework to multiple/rival return and risk scenarios. The optimal investment decision is evaluated in view of the worst-case scenario. The multi-period extension is considered to model non-liquid assets and the effect of transaction costs on the optimality of final performance. Robustness is not restricted to simply the mean-variance framework. Indeed, we also consider optimisation of multi-period conditional value at risk in view of rival representations of the future (in terms of scenario trees).

Abstract

We describe the calibration of spread options on power and natural gas forward prices whose dynamics are described by the Borovkova & Geman (2006) commodity forward price model. This two-factor model resolves the stochastic dynamics of the average value of the forward curve and the term structure of convenience yields, the latter of which incorporates seasonal effects. Capturing the seasonal volatility term-structure from historical prices is essential for accurate forward curve construction and subsequent option pricing. An attractive feature of the seasonal forward model is that the covariance of the forward dynamics is quadratic in the volatility term-structure and can be effectively calibrated to historical data using a non-linear gradient based constrained optimization algorithm. We show the comparative effect on calender spread and heating rate option prices through resolving the full term-structure of seasonal forward volatilities.

The talk will end with a more general and interactive discussion on how term-structure calibration methodology can be modified to account for major market dislocations.
