Arbitrage and Non-linear Taxes

Incorporating a progressive or convex income tax into valuation problems raises the question of the appropriate tax rate to use in common valuation formulas. We apply arbitrage theory in a riskless, as well as risky, (multi-period) economy to answer this question. It turns out that the appropriate tax rate depends on the marginal tax rate of the investor’s initial endowment.

With tax liabilities that are a convex function of the tax base, we identify a new kind of arbitrage: trading strategies where the gains from trades remain unchanged if this strategy is applied multiple times. We call these strategies ‘bounded’ arbitrage opportunities. Going beyond earlier research, we are able to give a complete characterization based on properties of the tax liability function as to whether bounded as well as unbounded arbitrage opportunities will exist.

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.

Mutivariate FX models with jumps: Triangles, Quantos and implied correlation

We propose an integrated model of the joint dynamics of FX rates and asset prices for the pricing of FX derivatives, including Quanto products; the model is based on a multivariate construction for Lévy processes which proves to be analytically tractable. The approach allows for simultaneous calibration to market volatility surfaces of currency triangles, and also gives access to market consistent information on dependence between the relevant variables. A successful joint calibration to real market data is presented for the particular case of the Variance Gamma process.

Griselda Deelstra is Professor in Stochastic Finance in the Department of Mathematics at the Université libre de Bruxelles (ULB), where she is the director of the Actuarial Sciences Group. Griselda Deelstra’s research interests focus on stochastic modelling in finance and insurance, in particular on risk management and derivative pricing. She holds a PhD from the Vrije Universiteit Brussel (1996). In her career, she had teaching/research positions at ENSAE and CREST, UGhent and VUB.

Pricing Cryptocurrency Options: the Case of CRIX and Bitcoin

The CRIX (CRyptocurrency IndeX) has been constructed based on a number of cryptos and provides a high coverage of market liquidity, The crypto currency market is a new asset market and attracts a lot of investors recently. Surprisingly a market
for contingent claims hat not been built up yet. A reason is certainly the lack of pricing tools that are based on solid financial econometric tools. Here a first step towards pricing of derivatives of this new asset class is presented. After a careful econometric pre-analysis we motivate an affine jump diffusion model, i.e., the SVCJ (Stochastic Volatility with Correlated Jumps) model. We calibrate SVCJ by MCMC and obtain interpretable jump processes and then via simulation price options. The jumps present in the cryptocurrency fluctutations are an essential component. Concrete examples are given to establish an OCRIX exchange
platform trading options on CRIX.

Realized Cryptocurrency Volatility Forecasting with Jumps: An Empirical Study

In this paper, to investigate the realized volatility process of the highly volatile cryptocurrency assets, we employ threshold realized variance method to separate jump component apart from continuous process. Jumps appear more frequently and significant comparing with other assets, we can find jumps bring more information, despite that the jump process doesn’t improve explanation power. The change of one-day lagged threshold jump component has significant positive impact on the change of future realized volatility, this suggest that investors are likely to find cryptocurrency market more volatile after jumps happened one day before. However, the un-threshold jump component is negatively correlated to the future realized volatility significantly. We then evaluate the economic values among a variety of forecasting results under a simple utility-based framework.

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.  Karel has also spent time in the industry, working as quantitative analyst at ABN Amro, Amsterdam.  He holds a PhD in Mathematics from Leiden University.

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.

Vadim Kanofyev

Quantitative Researcher

Bloomberg L.P.

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.

Vadim Kanofyev is a Quantitative Researcher at Bloomberg L.P. His research interests include quantitative asset allocation, algorithmic trading strategies and derivatives pricing. He has an extensive experience in numerical computing, applied machine learning and financial econometrics. Vadim holds a Master’s degree in Economics from the University of Pennsylvania.

Estimation of Volatility Surfaces via Functional Approximation and Machine Learning

Volatility surfaces are crucial for the pricing and hedging of a huge number of financial instruments, yet they cannot always be obtained reliably from financial markets for various reasons. In this talk we show how to predict volatility surfaces for equity underlyings in scenarios where a price estimation of the underlying is available. This is accomplished by leveraging a newly improved functional approximation algorithm in combination with supervised machine learning. This talk gives a formal introduction to the theoretical concepts and showcases real-world applications from the banking industry.

Portfolio Optimization with CoVar in Cryptocurrency Markets

Recently, a new approach for portfolio optimization with risk measured by Conditional Value-At-Risk (CoVaR) was suggested (Zalewska A., 2018). The approach is based on the stress event of chosen asset being equal to the opposite of its value-at-risk level, under the normality assumption. The current research investigates characteristics of the CoVaR oprimized portfolios applied to the universe of cryptocurrencies and stock indices serve as stress event assets. We test in- and out-of-sample performance compared with other widely used risk-based portfolio optimization rules, such as such as Mean-variance model (MV), Risk-parity (ERC) and Maximization diversification (MD). The empirical results show high potential of crypto-currencies for portfolio hedging and improve the risk-return profile of portfolios. Performance of CoVaR portfolio is strongly dependent on the level of stress event of the core asset.

Statistical Arbitrage

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.

Martin Simon works for the German asset management company Deka Investment where he is head of equity and equity derivatives valuation. His research interests focus on numerical analysis, high performance computing, mathematical modeling and uncertainty quantification with applications in pricing and hedging of equity derivatives, asset allocation and risk management.

Practical and quantitative issues to be solved trading and risk managing crypto assets

As a matter of fact, the Crypto Asset markets is a new asset market and attracts a lot of investors. In the last two years, we have seen a lot of new entrants in the market: crypto currency exchanges, security token platforms, stable coins, established financial services institutions that are launching crypto products and services. Crypto Assets are meanwhile impossible to ignore; even Amazon, Google, Alibaba, Starbucks etc. seem to think Crypto Assets are worth paying attention to. Whilst Crypto Assets may came to stay, they have been object of mixed reactions and expectations through the last years. Some investors saw cryptos as a unique way to diversify their portfolios and avoid some of the downsides of traditional bonds, stocks and commodities. Those investors rather disregard negative comparisons to the dot-com era by pointing to the Nasdaq Composite’s recovery 15 years later and the enormous potential of cryptos and blockchain on the  society. They also note that Bitcoin has rebounded from past crashes of similar magnitude. Others are concerned about market manipulation, money laundering, excessive hype, security flaws, tighter regulation and slower-than-anticipated adoption by Wall Street. However, a soundstanding market for Crypto Currencies, Futures&Options and other Crypto Derivatives has not been built up yet with regards to regulations, transparency, liquidity, reliable valuation and pricing tools. Since Crypto Assets are still immature, they will become less volatile as they mature. First steps towards pricing and margining of Crypto Derivatives and how to measure the risk of Crypto Assets can now be presented. Sophisticated statistical methods and analysis classified cryptocurrencies as a new asset class with unique features in the tails of the distribution and confirm the potential of crypto-currencies for portfolio hedging and improve the risk-return profile of portfolios.

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.
