Derivative pricing: A pattern-matching problem?
Before computers became a handy tool available to everyone everywhere, pricing of financial options was mainly a matter of experience, a pattern matching task performed by human neural networks. This changed drastically with the advent of the Black-Scholes equation an the availability of computer power which enables everyone to price options in no time. Today, the pricing of derivatives has become a more complex, sophisticated exercise and enormous computer power is required to calculate all the needed portfolio-based risk figures (e.g. XVA). In this case study, we examine if the application of deep neural networks, which allow pricing of complex derivatives in constant time, could be helpful.
Dr. Mark Beinker is partner at d-fine GmbH and head of d-fine’s derivative valuation consulting business. With more than 20 years of experience in this field, he has been responsible for projects covering all aspects related to derivative pricing, including specification, implementation and testing of new and old pricing models, selection of third party tools, estimation of risk figures and valuation adjustments, and the design and specification of IT infrastructure and business process required for efficient valuation and processing of financial derivatives. He is also responsible for d-fine’s bespoke pricing library MoCo and tools based thereon. Before he joined d-fine he worked as a manager at Arthur Andersen. He holds a PhD in theoretical particle physics.

Numerical Valuation of Bermudan Basket Options via Partial Differential Equations
We study the efficient numerical valuation via partial differential equations of Bermudan basket options with a large number of underlying assets. To deal with the high-dimensionality of the problem, we combine the principal component analysis from Reisinger & Wittum (2007) with modern alternating direction implicit (ADI) schemes, see e.g. in ‚t Hout & Welfert (2009). The convergence of this combined analytical-numerical approach is investigated in detail, and ample numerical experiments are presented illustrating the high performance it attains. This is joint work with Jacob Snoeijer (U Antwerp).
Karel in ’t Hout is Associate Professor in the Department of Mathematics and Computer Science at University of Antwerp, specializing in the analysis and development of numerical methods for time-dependent partial differential equations with applications to finance. He has previously held positions as Visiting Professor at Arizona State University, Visiting Professor at Boise State University and Researcher at Leiden University and University of Auckland.

VIX Options in Rough Volatility Models
We discuss the pricing and hedging of volatility options in some rough volatility models. First, we develop efficient Monte Carlo methods and asymptotic approximations for computing option prices and hedge ratios in models where log-volatility follows a Gaussian Volterra process. While providing a good fit for European options, these models are unable to reproduce the VIX option smile observed in the market, and are thus not suitable for VIX products. To accommodate these, we introduce the class of modulated Volterra processes, and show that they successfully capture the VIX smile. Joint work with Blanka Horvath and Peter Tankov.
Dr Jacquier is a Senior Lecturer in the Department of Mathematics at Imperial College London. His research focuses on volatility modelling, with a special emphasis on rough volatility and applications of asymptotic methods in finance. He holds a PhD in Mathematics from Imperial College London, has co-edited a book on Asymptotic Methods in Finance, and has published more than 30 papers in mathematical finance and applied probability.
Machine Learning for Factor Investing
Style investing helps to construct portfolios that deliver positive long-term returns and have a low correlation with the market. We study the benefits of use of various machine learning techniques on the portfolio construction and „style“ selection stages. The goal of the first stage is to find an optimal combination of the asset characteristics, which has a superior predictive power of the future returns. On the second stage we use macro economic parameters to study the „style“ factor rotation to construct a composite portfolio that is comprised of individual factor-based strategies.

Volatility Swaps: PDE Pricing Improvements for LSV frameworks
We study one dimensional PDE pricing techniques for volatility swaps that are able to closely replicate Local Stochastic Volatility Monte Carlo prices also in the context of fairly oscillating volatility term structure, while sensibly improving the computational performance. Our analysis is based on Foreign Exchange (FX) volatility swaps, but can be equivalently applied to other asset classes.
Jacopo is a quant at Barclays, which he joined in March 2017. His main focus is PDE pricing in LSV and Hybrid models for FX. Prior to that, he earned a PhD in Financial Mathematics at the LMU University in Munich, working on Model Uncertainty under the supervision of Prof. Dr. F. Biagini.

Generalized arbitrage in the sense considered here corresponds to trading strategies which yield positive gains on average in a class of scenarios rather than almost surely. The relevant scenarios or market states are specified via a sigma-algebra and so this notion contains classical arbitrages as a special case. It also covers the notion of statistical arbitrage introduced in Bondarenko (2003). Relaxing these notions further we introduce generalized profitable strategies which include also static or semi-static strategies. We show that even under standard no-arbitrage (NA) there may exist generalized gain strategies yielding positive gains on average. In the first part of the paper we characterize these generalized no-arbitrage notions. In the second part of the paper we explicitly construct profitable generalized strategies and study their performance on simulated data and on market data. These strategies, albeit simple in nature, show a surprising performance being profitable on average with little remaining risk. This is joint work with Christian Rein and Ludger Rüschendorf.
Thorsten Schmidt is Professor for Mathematical Stochastics at University Freiburg (successor of Ernst Eberlein). Prior to this he was professor for Mathematical Finance at Chemnitz University of Technology since 2008, held a replacement Professorship from Technical University Munich in 2008 and was Associate Professor at University of Leipzig from 2004 on. His Ph.D. he obtained from University in Giessen in 2003 on credit risk with infinite dimensional models. Besides his interests in Mathematical Finance, in particular interest rates, credit risk and energy markets, he has a strong background in statistics and probability theory. His research focusses on topics in mathematical finance and the theory and application of stochastic processes. This includes credit risky markets, interest rate markets, dynamic term structure models, insurance mathematics, energy markets and related fields.

Stock Price Bubbles – An Option-based Indicator
In this talk we are going to discuss an option-based mathematical indicator for stock price bubbles. The first introductory part recaps the strict local martingale theory for modeling asset price bubbles and its implications for pricing contingent claims. In the second part we present a novel forward-looking indicator based on the information content of bid and ask market quotes for exchange-traded plain vanilla options. Our construction is motivated by a recent theoretical result by A. Jacquier and M. Keller-Ressel proving that bubbles can be identified from the asymptotic behavior of the implied volatility surface. However, in practice, the resulting inverse parameter identification problem is ill-posed and we adopt a statistical perspective in order to cope with this ill-posedness and to quantify the indicator’s inherent uncertainty. Finally, we provide real-market tests of the proposed indicator with focus on tech stocks addressing increasing concerns about a tech bubble 2.0. The talk is based on joint work with Lassi Roininen, Petteri Piiroinen and Tobias Schoden.

Separating the asset universe from cryptocurrencies
The aim of this paper is to find the proximal genus and the specific difference (genus proximum et differentia specifica) for the daily time series of cryptocurrencies returns, compared to classical asset returns.
In this sense, a daily time series of asset returns (either crypto or classical assets) can be characterized by a multidimensional vector with statistical components like volatility, skewness, kurtosis, tail probability, quantiles, expected shortfall or fractal dimension.
By using dimension reduction (Factor Analysis) and classification models (Support Vector Machines) for a representative sample of cryptocurrencies, stocks, exchange rates and commodities, we are able to classify cryptocurrencies as a new asset class with unique features in the tails of the distribution.
