Cloud Calculation Service for the FX Volatility Smile

The Cloud Calculation Services for MathFinance AG‘s  MFVal Library demonstrates how calculations can be deployed to the cloud by using BCCG’s Financial Data Enterprise Platform called “ONE”. The invocation of calculations is hereby, as an example, triggered from Excel, sent as JSON command to the Cloud Micro Services and the calculation results are received back into Excel. The implementation is a generic approach that can be applied to any Math Library that complies to a specific functions structure. Linux, Docker and Windows Platforms are supported. We show examples how market data can be used to generate the FX volatility smile: volatility on the strike space, variance on the log-moneyness space and the probability density. This allows systematic analysis of market data for the purpose of trading or model validation.


Following a range of roles in Software Development, Dealing Room Support and Project management starting in 1988, Mauricio founded BCC Group back in 2003. From 2007 he focused the company on developing a vendor agnostic Market Data Messaging Platform based on Solace Systems Appliances (FMDP). After 4 years of testing and redesign with joint forces from Solace Systems, Royal Bank of Canada and DZ BANK, BCC Group released FMDP which, as a result got certified by Bloomberg for connection to their data.

A discrete-time stochastic volatility model with Meixner innovations

We suggest a multi-factor stochastic volatility model based on autoregressive gamma processes. Model innovations are Meixner distributed. The model is specified under the historical measure based on a stochastic discount factor, which features compensation of both return and volatility risk. We are able to fully characterize the data generating process under the risk neutral pricing measure. The model captures major stylized facts of equity data such as unconditional asymmetry and fat-tailedness, conditional skewness and conditional kurtosis, stochastic volatility and rich patterns of cross and serial correlation of the return process. The model is exponentially affine; hence standard option pricing approaches can be applied for evaluating plain vanilla options. We present empirical results for S&P 500 data.

Prof. Dr. Matthias R. Fengler is a Professor of Econometrics at the University of St. Gallen (HSG), Switzerland. Matthias’ main area of research is financial econometrics with applications in risk management and asset pricing.

Panel: Recent Challenges in Derivatives Technology

Most observers focus on regulatory changes, like MiFID II and PRIIPS, when currently talking on structured products. However, besides regulation another major factor for competitiveness is technology. Pricing, issuance, execution, documentation, and settlement have to be done – at least for standard structures – automatically. This trend has become apparent with the multi issuer platforms, for example, which enable even private retail investors in Germany to get real-time prices for investment certificates from different issuers, to request the issue of a certain structure without any obligation for a minimum investment and to purchase the new product some minutes later via a bank at a stock Exchange.

Wolfgang Gerhardt has played an active role in the development of the markets for structured products in Germany and other European countries since the early 90s. He has been Head Financial Products Germany of Vontobel Group since September 2010 and Speaker of the Management Board of Bank Vontobel Europe AG. In this position he is in charge of the business with investment certificates and leverage products of the Swiss banking group in Germany and the recent expansion into other European countries, among others are Sweden, Italy, and France.

After graduating from Wuerzburg University he had various capital markets responsibilities for CSFB-Effectenbank, Schweizerischer Bankverein (Deutschland), Citibank and Sal. Oppenheim jr. & Cie. From 2008 until 2010 he was a member of the Executive Board at Bank Sal. Oppenheim jr. & Cie. (Schweiz) AG in Zurich responsible for investment banking.

Symposium on Numerical Methods:
Complexity Reduction Techniques for Finance

Model calibration requires fast and accurate numerical methods. In the current paradigm, semi-closed pricing formulas for liquid options are seen as a prerequisite for modelling financial asset evolution. Thus attention is restricted to stochastic processes that are simple enough to allow for straightforward expressions of the pricing formulas. This obviously imposes a severe modelling restriction. However, rising demands to include more realistic features, for instance stylized facts on asymptotics of the implied volatility surface, compel us to consider a wider class of processes and hence more complex models. We therefore propose numerical techniques to reduce the computational complexity of the resulting pricing tasks. In this talk we focus on interpolation of option prices in the parameter space. Both the theoretic and experimental results show highly promising gains in efficiency. The efficiency gain is particularly high in cases where Monte Carlo simulation is required and prices need to be computed for a large number of parameter constellations.

Kathrin Glau currently is a Junior Professor for Mathematical Finance at the Technical University of Munich. Prior to this she worked as a postdoctoral university assistant at the chair of Prof. Walter Schachermayer at the University of Vienna. In September 2010 she completed her Ph.D. on the topic of Feynman-Kac representations for option pricing in Lévy models at the chair of Ernst Eberlein.

Her research is driven by the interdisciplinary nature of computational finance and reaches across the borders of finance, stochastic analysis and numerical analysis. At the core of her current research is the design and implementation of complexity reduction techniques for finance. Key to her approach is the decomposition of algorithms in an offline phase, which is a learning step, and a fast and accurate online phase. The methods range from model order reduction of parametric partial differential equations to learning algorithms and are designed to facilitate such diverse tasks as uncertainty quantification and calibration, real-time pricing, real-time risk monitoring, and intra-day stress testing.

A Universal Pairwise Local Correlation Model

In this paper we develop a local correlation model which uses a universal function g(t,m_i,m_j) to describe the local correlation between any asset-asset pair of a basket of underlyings. The arguments m_i,m_j are spot moneynesses.The universal function is calibrated to fit the implied volatilities of an equity index like DAX or EUROSTOXX50. The advantage of this approach is that we do not need to simulate the complete index when pricing options on a usually small subset of this index. The approach does also not suffer from the so-called chewing gum effect of correlation models where the local correlation depends on just the index value. The main part of our work is to show how to calibrate the universal function for each time step such that the resulting correlation matrices are positive definite almost anytime and that the function is sufficiently smooth to allow for stable evaluation.

Frank Koster works as a quant for DekaBank, a German fund manager. He holds a Ph.D. in Scientific Computing/Numerical Analysis from the University of Bonn (Germany).

His first position outside academics was with Mercedes-Benz where he developed and applied simulation methods and shape optimization software for Formula-One race engines (engines with his contributions were awarded ‘Race Engine of the Year’ in 2008 and 2009).

After that he moved into Finance working for Sal.Oppenheim and MacQuarie Capital. His main areas of work are numerical methods/models for equity derivatives.

Replacing VaR by ES – much ado about nothing?

Basel plans to replace the risk measure Value at Risk 99 by Expected Shortfall 97.5 as of 2018. We briefly compare both measures from a theoretical angle – thereby going a bit beyond the coherence properties – before we carry out an empirical investigation concerning equity and credit portfolios. The results put the regulatory initiative into question. Not only can it happen that the opposite of the intended impact is achieved, but also that the whole exercise turns out to be much ado about nothing. The presentation is based on joint work with Prof. Dr. Daniel Ziggel and M. Sc. Christina Strate, both from FOM University of Applied Sciences.

Frank started his professional career in 1994 at WestLB as Financial Engineer for exotic derivatives and intraday trading systems, followed by an appointment as Head of Analytics & Systems in the central credit risk management in 1998. In 2001 he moved on to DG HYP (DZ BANK group) in Hamburg, initially as Head of Credit Risk Controlling, since 2002 equipped with credit competence as Head of “Credit Portfolio Management and Structured Investments” in Credit Treasury. In parallel, Frank built up the special servicer “Immofori GmbH” where he was Managing Director from 2004 to 2006. In 2007 he moved to IKB Credit Asset Management GmbH and was appointed as Managing Director in March 2007. He was involved in crisis management concerning the balance sheet of IKB AG, the conduit “Rhineland” and the structured investment vehicle “Rhinebridge”. From 2009 to 2015 he worked for RWE in various roles (2009-2010 in Risk Management, since 2011 in Front Office in Commodity Trading). Since 2015 he is professor of risk management at FOM Applied University in Dusseldorf, Germany.

Symposium on Numerical Methods:
On an efficient one and multiple time-step Monte Carlo simulation of the SABR mode

In this work, we propose an efficient Monte Carlo simulation for the SABR model. The technique is based on an efficient simulation of SABR’s integrated variance process. The integrated variance process appears in the SABR model simulation since it is part of the conditional cumulative distribution of the SABR forward asset dynamics. We base our approach on the derivation of the cumulative Distribution function of the integrated variance and the use of a copulas to approximate the conditional Distribution (integrated variance conditional on the SABR volatility process). For that, a recursive procedure based on Fourier numerical techniques recovers the probability density function given the corresponding characteristic function. Resulting is a fast and accurate simulation algorithm. The one time-step version can be employed to price European options under the SABR dynamics. This converts this approach into an alternative to Hagan analytic formula for short maturities and calibration procedures. On the other hand, the multiple time-step extension of our technique is specially useful for long-term options and for exotic options.

Álvaro Leitao is a PhD student at the Delft Institute of Applied Mathematics (DIAM) in the Delft University of Technology and a PhD researcher at Scientific Computing department in the National Center of Mathematics and Computer Science (CWI), under the supervision of Prof. Cornelis W.

Symposium on Numercial Methods:
Calibration of a Four-Factor Hybrid Local-Stochastic Volatility Model with a New Control Variate Particle Method

We propose a novel and generic calibration technique for four-factor foreign-exchange hybrid local-stochastic volatility models with stochastic short rates. We build upon the particle method introduced by Guyon and Labordère [Nonlinear Option Pricing, Chapter 11, Chapman and Hall, 2013] and combine it with new variance reduction techniques in order to accelerate convergence. We use control variates derived from a calibrated pure local volatility model, a two-factor Heston-type LSV model (both with deterministic rates), and the stochastic (CIR) short rates. Our numerical experiments show that because of the dramatic variance reduction we are able to calibrate the four-factor model at almost no extra computational cost when the corresponding calibrated two-factor model is at our disposal. The method can be applied to a large class of hybrid LSV models and is not restricted to our particular choice of the diffusion. The calibration procedure is performed on real-world market data for the EUR-USD currency pair.

Matthieu is a PhD candidate in Mathematics at the University of Oxford. He focuses his research on the application of stochastic analysis and numerical methods to Quantitative Finance. More specifically, he concentrates on the calibration of mathematical models to accurately price exotic derivatives.

Current developments in model risk measurement

Model risk has been a concern ever since models have been used for pricing and risk management of trading positions. Recent updates in regulatory frameworks (FRTB, EBA “prudent valuation”) set out concrete requirements for model risk measurement. After giving an overview of regulatory developments and requirements, we develop value-at-risk and expected shortfall measures for model risk based on realised P&L from model risk. We further demonstrate how the model risk framework can be used to assess the hedge quality in incomplete markets with jumps. This helps explain why in some markets deliberately misspecified, but complete, market models are preferred over more appropriate but incomplete market models.

Natalie Packham is Professor of Mathematics and Statistics at Berlin School of Economics and Law. Natalie has several years of industry experience as a front office software engineer at an investment bank, and is frequently involved in industry-related research and consulting projects. Her research expertise includes Mathematical Finance, Financial Risk Management and Computational Finance, and her academic work has been published in Mathematical Finance, Finance & Stochastics, Quantitative Finance, Journal of Applied Probability and many other academic journals.

How Accurately Did Markets Predict the GBP/USD Exchange Rate Around the Brexit Referendum?

We develop a model for the British pound/US dollar exchange rate around the Brexit referendum in June 2016. Applying the model to a combination of betting market odds and financial option prices, we show that while Leave was the least likely outcome (more unlikely, in fact, than betting odds would immediately suggest), predictions of the exchange rate conditional on the outcome of the referendum were accurate and the market was able to separate its views on the likelihood and the impact of Brexit.

Rolf Poulsen is a professor of Mathematical Finance at the Dept. of Math. Sciences at the University of Copenhagen. His main research interest is quantitative methods for pricing and hedging of derivatives. He will talk about exchange rate markets at length to all who will listen – and some who won’t.

Adaptive Market Risk Measurement in the Trading Book

Current regulatory capital calculation in most financial institutions heavily relies on stationarity assumptions related to the underlying risk drivers. Nevertheless empirical studies show that non stationarity is one of the prevailing stylized facts in financial markets. This presentation describes a straightforward extension of already existing internal market risk models to cope with rapidly changing market conditions. The performance of this so called adaptive market risk method is demonstrated using financial market data as well as Monte Carlo simulation exercises based on different time series models as well as Fractional Brownian Motion.

Dr. Peter Quell is Head of the Portfolio Analytics Team for Market and Credit Risk in the Risk Controlling Unit of DZ BANK AG in Frankfurt. He is responsible for methodological aspects of Internal Risk Models, Economic Capital and Model Risk. Prior to joining DZ BANK AG Peter was Manager at d-fine GmbH where he dealt with various aspects of Risk Management Systems in the Banking Industry. He holds a MSc. in Mathematical Finance from Oxford University and a PhD in Mathematics. Peter is member of the editorial board of the Journal of Risk Model Validation.

Quasi-Gaussian Model for Model Validation and Pricing Analysis

Validation of pricing models for structured rates products relies on powerful benchmark models that allow capturing the various risk factors like volatilities, skew and correlation. In this presentation we analyze the class of Quasi-Gaussian interest rate models. This includes model parametrization and calibration methodologies.

Moreover, we demonstrate how Quasi-Gaussian models can be applied to disentangle effects arising from the different risk factors involved. This improves transparency on product features and may help to understand price quotes from different internal and external sources.

Sebastian Schlenkrich is Manager in the Financial Engineering unit at d-fine, a leading consultancy company specialised in risk and finance. In this role he manages and delivers client projects on current valuation and risk management topics. Previously, in the Macro Valuation Methodologies Team at UBS Investment Bank, London he held global responsibilities for methodology and tool development of pricing model validation.

A focus of his research and work are valuation methodologies for interest rate, FX and hybrid derivatives. Furthermore he works in the field of Algorithmic Differentiation and its application in finance.

Unbiased estimation of risk measures

Recently, the estimation of risk measures gained a lot of attention, partly because of the backtesting issues related to elicitability. In this work we shed a new and fundamental light on the biasedness of estimation of risk measures. We show that once the parameters of a model need to be estimated, one has to take additional care when estimating risks. The typical plug-in approach, for example, introduces a significant bias which leads to an underestimation of risk. Moreover, backtesting will consequently fail with models which do fit the data due to the additional bias. We give a number of motivating examples which show the outperformance of unbiased estimators in many circumstances.
(This is joint work with Marcin Pitera.)

Sovereign Bond Network Dynamics

From 2004 to 2016, the market perception of the sovereign risks of euro area government bonds experienced several different phases, reflected in a clear time structure of the correlation matrix between the yield changes. “Core” and “peripheral” bonds cluster in a bloc-like structure, but the correlations between the blocs are time-dependent and even become negative in periods of stress.

Using noise-filtered partial correlation influences, this time-dependency can be evaluated and visualized using network graphs.

Our results support the view that market-implied spill-over risks have decreased since the European rescue and stability mechanisms came into force.
In 2015, spill-over risks reappeared during the Eurogroup’s negotiations with Greece, although the periphery yields did not show risk spreads that were as large as those in 2012.
We also discuss the 2016 market movements before and after the Brexit referendum, the US election and the Italian constitutional referendum.

Peter Schwendner is a Senior Lecturer at the Institute for Wealth and Asset Management at ZHAW School of Management and Law, Zurich, Switzerland.

Robo Advisors: The Algorithms behind the User Screens

Robo advisors are portfolio management platforms that are based on quantitative algorithms and work with minimum human intervention. Currently, the robo advisors are considered as a disruptive trend in wealth management, and according to the different forecasts the robo advisors will globally manage from $2 to $8 trillion by 2020, which is 2.5 – 10% of total global assets under management.
The quantitative methods used in the robo advisors are diverse, yet most of the systems employ classical Markowitz’s mean-variance optimization. This approach is usually complemented by various methods to mitigate such issues as highly-concentrated portfolios, input-sensitivity, and estimation error maximization (constraints set, Black-Litterman, capitalization-specific allocation, etc.).
We provide an overview of both the business and quantitative methods of the robo advisors. Besides, we outline promising approaches and challenges in the implementation and testing of the robo advisory systems.

ADI Finite Difference Schemes for the Calibration of Stochastic Local Volatility Models: An Adjoint Method

In contemporary financial mathematics, stochastic local volatility (SLV) models form state-of-the-art models to describe asset price processes. The local component of the SLV model, the so-called leverage function, is defined in a natural way such that the SLV model yields the same fair value for vanilla options as the underlying local volatility (LV) model. Determining this leverage function is, however, a highly non-trivial task. For example, the fair option values defined by the LV model can often not be obtained analytically and have to be approximated, e.g. by numerically solving the corresponding backward PDE.

Consider any given discretization by finite differences of the one-dimensional backward PDE from the LV model and suppose discretization of the two-dimensional backward PDE corresponding with the SLV model is performed by similar finite difference formulas. In this talk we shall propose a calibration technique with the useful property that it determines the leverage function such that both discretizations define exactly the same approximation for the fair value of vanilla options. In this calibration procedure, which involves a two-dimensional PDE problem, alternating direction implicit (ADI) time stepping schemes are used as they are highly efficient in comparison to classical implicit methods. Ample numerical experiments are provided that illustrate the effectiveness of this calibration procedure.

Maarten Wyns is a PhD student at the Department of Mathematics and Computer Science of the University of Antwerp (Belgium). He obtained his M.Sc. in Financial Mathematics in 2013 at the Vrije Universiteit Brussel. During his young research career, he published several papers on the convergence of state-of-the-art Alternating Direction Implicit (ADI) schemes for the numerical solution of PDEs from financial mathematics. Currently, Maarten is working on numerical (PDE) methods for the calibration of local stochastic volatility models.
