Dr. Beatrice Acciaio


 ETH Zurich

Quantifying Arbitrage

In this talk I will present a way to quantify arbitrage, that allows to deal with model uncertainty without imposing the no-arbitrage condition. In markets that admit “small arbitrage”, we can still make sense of the problems of pricing and hedging. The pricing measures here will be such that asset price processes are close to being martingales, and the hedging strategies will need to cover some additional cost. We show a quantitative version of the Fundamental Theorem of Asset Pricing and of the Super-replication theorem. We study robustness of the amount of arbitrage and existence of respective pricing measures, showing stability with respect to a new, strong adapted Wasserstein distance. Based on joint work with J. Backhoff and G. Pammer

Berlin School of Economics and Law

Risk Factor Detection with Methods from Explainable ML 

The importance of risk management in the financial industry has increased rapidly since the financial crisis, in particular with regard to financial market stability. A particular focus is on stress testing methods, which captures portfolio risk under adverse conditions. Advances in statistical learning and the availability of large, granular data sets offer new methodological possibilities for stress testing. Financial risk management applications such as hedging, scenario analysis and stress testing rely on portfolio models based on risk factors. In addition to observable risk factors, factor models with non-observable, data-based factors offer interesting alternatives. However, the lack of interpretability of the output is limiting. We develop time-dynamic methods for the interpretability of principal components (PCA), which allow to generate aggregated risk factors from existing risk factors. This aggregation makes it possible to plausibly implement less granular and even global stress scenarios. 

Natalie Packham is Professor of Mathematics and Statistics at Berlin School of Economics and Law and Principal Researcher within the International Research Training Group “High Dimensional Nonstationary Time Series” (IRTG 1792) at Humboldt University Berlin.

MathFinance Conference 2023 Speakers - MathFinance

Dr. Markus Hertrich

Senior Economist

Deutsche Bundesbank

An Options-based Approach to Test for the Existence of an undeclared Exchange Rate Target Zone

Many central banks worldwide intervene in the foreign exchange market with the aim of stabilizing the foreign value of their currency. To achieve this goal, they either target a specific level or a specific range, often with undeclared bands. Under these regimes, the design and calibration of hedging strategies for foreign exchange option exposures will be affected. Financial market participants managing their risk exposures in a forward-looking manner, will therefore have to recur to a statistical test to assess the existence of implicit bands. For this purpose, no method exists that can be used currency option markets. The present paper fills this gap and proposes a test that can easily be implemented.

Markus Hertrich is a senior economist in the Directorate General Economics and the Research Centre of the Deutsche Bundesbank in Frankfurt am Main (DE) and a post-doctoral research fellow at the University of Basel (CH). He earned his PhD in economics in 2014 from the University of Basel after completing the Swiss National Bank’s program for doctoral students in economics in Gerzensee in 2010. His professional experience also includes several of lecturing and conducting research in empirical finance and international economics and three and a half years working as a financial analyst within the asset management unit of a major Swiss bank.

Reka Janosik

Executive Director


Measuring Climate Impact and Climate Risk and the connection to the Probability of Default

Financial regulators are incentivizing the financial industry to assess their climate-related risks using climate-scenario analysis. MSCI’s climate stress test approach is explained and a special focus on credit risk of corporate debt is given, as climate change may cause rating downgrades and a corresponding widening in spreads. MSCI’s bottom-up climate scenarios can shed light on the impact of climate change on default probabilities and ratings migrations. Beyond any regulatory requirements an overview is given how climate impact and climate risk can be measured and why both is needed to take better investment decisions for a better world and protecting wealth.

Patrick is an Executive Director at MSCI and heads the Analytics Consultant Team based in Frankfurt, Germany. His team supports financial institutions in the GAuS region (Germany, Austria, Switzerland) in a large variety of use cases including portfolio risk assessment, regulatory risk reporting as well as factor investing and portfolio construction. Patrick studied mathematics and informatics at the Johannes Gutenberg University Mainz where he also acquired his doctoral degree in statistics and probability theory.

Dr. Andrea Mazzon

Lecturer in Financial Mathematics

Ludwig Maximilians Universität (LMU)

Detecting Asset Price Bubbles using Deep Learning

We employ deep learning techniques to detect financial asset bubbles by using observed call option prices. The proposed algorithm is widely applicable and model-independent. We test the accuracy of our methodology in numerical experiments within a wide range of models and apply it to market data of tech stocks in order to assess if asset price bubbles are present. Under a given condition on the pricing of call options under asset price bubbles, we are able to provide a theoretical foundation of our approach for positive and continuous stochastic asset price processes. When such a condition is not satisfied, we focus on local volatility models. To this purpose, we give a new necessary and sufficient condition for a process with time-dependent local volatility function to be a strict local martingale.


Andrea Mazzon is Lecturer in Financial Mathematics at the Ludwig Maximilians Universität (LMU) in Munich. He owns a PhD in Mathematics in Natural, Social and Life Sciences from the Scuola Superiore di Studi Avanzati of Trieste.

Dr. Thomas Barrau

Head of Intraday Research

AXA Investment

Predicting Stock Market Drawdowns using Polymodels

We propose a Systematic Risk Indicator derived from a polymodel estimation. Polymodels allow us to measure the strength of the links that a stock market maintains with its economic environment. We show that these links tend to be more extreme before a market crisis, confirming the well-known increase of correlations while proposing a more subtle perspective. A fully automated and successful trading strategy is implemented to assess the interest of the signal, which is shown to be strongly significant, both from an economic and statistical point of view. Results are robust across different time-periods, for various sets of explanatory variables, and among 12 different stock markets.


Thomas Barrau is Head of Intraday Research for the hedge fund AXA Investment Managers Chorus Ltd. He is leading the development of a portfolio of quantitative intraday trading strategies invested in various asset classes.

With Raphael Douady, he co-authored the book “Artificial Intelligence for Financial Markets: The Polymodel Approach”, published by Springer.

He has been a Senior Quantitative Researcher at AXA IM Chorus, a role during which he developed a team of 4 researchers working on an Equity Market Neutral portfolio. Prior to this, he worked at Societe Generale as banker and financial advisor to small businesses, and as CFO in an aerospace company. He holds a PhD in Applied Mathematics from Paris 1 Pantheon-Sorbonne University. Previously, he validated with honors three different Masters of Science from Aix-Marseille School of Economics, Ca’Foscari University of Venice and Poitiers IAE.

Market-Maker Hard Exit Thresholds Strategy

 Whilst the academic research into the Market-Maker Problem has produced invaluable insights into the optimisation of risk exposure and expected profits, there are still gaps between the state of the art and the problem Market-Makers face in practice. Prominently among these gaps feature the fact that market-makers turn to price-takers more often than theory suggests, as well as the presence of uncertainty regarding price information and liquidity availability. In fact, the latter two account for much of the differences of the Market-Maker Problem across markets. Hence, whatever algorithm for optimal control is put in place, the market-maker often needs to apply pragmatic risk mitigation that attempts to limit, or exclude, outcomes beyond a given severity. In that vein, we derive closed-form expressions to place hard exit thresholds, i.e. stop-loss and take-profit prices levels and maximum holding time. These explicit formulae are for the Brownian motion with drift on an interval, subject to an exponential stopping time and a maximum set time. They are fast enough to be used at runtime in a large range of applications, including electronic trading. Several other problems can be addressed with the formulae presented, e.g. placement of bid and ask prices for a target hit-ratio, portfolio selection or calibration of risk aversion parameters.

Carlos Veiga is a Director in the Quantitative Strategies and Data Group, part of the Global Markets division of Bank of America. Currently he is part of the Data Tools & Solutions group focussing on leveraging the data available at the firm to enhance business performance and risk management. He has had other roles in quantitative analytics ranging from Rates, Equities and FX, as well as Counterparty Credit Risk and Market Risk. He has also ran an Equity Derivatives desk at a large Portuguese bank with business in exotic structured products, listed warrants and certificates and futures arbitrage.

Carlos holds an MSc in Economics and an MSc in Mathematics, both from the New University of Lisbon, and a PhD in Quantitative Finance from Frankfurt School. He has several papers published in academic journals, including Review of Derivatives Research and Applied Mathematical Finance.

Dr. Jürgen Hakala

Managing Director

Leonteq Securities AG

Ticking Away – The Cost of Time Passing

Theta is one of the greeks that appears in many textbooks just after delta, gamma and vega. In the Black-Scholes model it is well understood and is quite central as it links profit and loss of a hedged position to the bill of holding the position. In reality the textbook theta is not the end of the story to understand the time decay of a portfolio of exotics. We will shed some light on the various aspects of the practical determination and usage of theta in non Black-Scholes type models and the link to profit and loss calculations.

Jürgen works for Leonteq Securities AG, where he is involved in modelling and financial engineering for all asset classes. His interests lie in numerical methods in mathematical finance, in particular multi—asset and hybrid modelling, as well as the impact of regulation onto markets and models.

As his PhD was on Neural Networks he recently rediscovered his earlier interest in machine learning methods, now applicable to problems in financial engineering. Initially he worked on foreign exchange, where he co-edited several textbooks and papers.

Dr. Arun Verma

Senior Quantitative Researcher

Bloomberg L.P.

Quantitative Trading Strategies and Asset Pricing using Alternative Data and Machine learning

Machine Learning (ML) and Predictive Analytics are now embedded in a broad variety of use cases in Quantitative Finance, from information extraction to sentiment analysis, from factor scoring models to complex instrument pricing methods, and from risk premium mining to portfolio construction models. ML is also being used for asset pricing, e.g, option pricing or illiquid bond pricing where we need to learn the pricing function using data driven techniques as a further enhancement of methods rooted in stochastic modeling.

Quant traders and data scientists require automated ML & AI technologies to quickly extract actionable information from unstructured and increasingly non-traditional sources of data. We will illustrate the use of such derived signals in constructing promising trading strategies through novel use cases.

This talk will provide a brief overview of the following topics:

  • The broad application of machine learning in finance: opportunities and challenges.
  • Machine Learning techniques for asset pricing, enhancing complex quant models (i.e., PDE, Monte Carlo) for an efficient pricing of derivative securities and pricing of illiquid securities using data driven methods.
  • Collaborative filtering techniques for illiquid instrument pricing, use of data driven cohorts/drivers to inform price movements in a target instrument based on observations on other instruments in the market.


Arun heads the Bloomberg Quantitative Research Solutions Team. Arun’s work initially focused on Stochastic Volatility Models for Derivatives & Exotics pricing/hedging and more generally around asset pricing using traditional quantitative finance methods. More recently, he has enjoyed working at the intersection of diverse areas such as data science, innovative quantitative finance models and using AI/Machine Learning methods to help reveal embedded signals in traditional & alternative data such as Company Financials, ESG, News/Social, Supply Chain, Geolocational & Extreme Weather and their potential impact on capital markets. Most recently in an attempt to complete a full circle, he has been exploring use of ML methods in asset pricing , e.g. Derivatives pricing and illiquid instrument pricing.

Prior to joining Bloomberg, he earned his Ph.D from Cornell University in the areas of computer science and applied mathematics and a B. Tech in Computer Science from IIT Delhi, India. Arun is also an editorial board member of The Journal of Financial Data Science.

Dr. Anmar Al Wakil

Senior Data Scientist


Pricing the Market Impact of Credit Events in Corporate Bonds

In this presentation, we evaluate the impact of credit-related announcements on corporate bond prices, conditioning news on past bond performance and news sentiment. We find:

  1. A “surprise” effect: Conditioning credit ratings, equity actions, and stock prices on good news and poor past performance generates significant positive abnormal bond returns. Conditioning credit ratings, analyst ratings, and price targets on bad news and good past performance generates long-lasting outperformance.
  2. A “buy the rumor, sell the news” effect: Conditioning credit ratings, equity actions, analyst ratings, price targets, and stock prices on good news and good past performance generates negative abnormal bond returns.

 A combined strategy outperforms: A strategy excluding good announcements associated with good past performance while targeting unexpected events outperforms the unconditional strategy and individual strategies. The combined strategy generates annualized returns of 200 bps above the annual credit benchmark at a two-day effective holding period, and 90 bps at the one-week holding period, compared to 50 bps for the unconditional strategy.


Anmar is a senior data scientist at RavenPack. Before joining RavenPack in 2021, he worked as a quantitative researcher at Natixis Investment Managers for nearly 8 years, where he developed systematic investment strategies within the technology platform. At RavenPack, Anmar excavates cutting-edge insights from news sentiment to elaborate alpha-generating strategies across equity, credit, and derivatives instruments. In addition, he advices some of the world’s top hedge funds and asset managers on the use of NLP-driven analytics in finance.

He holds a PhD in Quantitative Finance from the University of Paris Dauphine-PSL along with a Master’s degree in Mathematical Finance. Anmar has written articles in portfolio selection and machine learning that were presented in multiple conferences. His article about asset pricing won the Best Doctoral Paper of the Multinational Finance Society. He is also a part-time Associate Professor at the University of Paris-Est where he heads the MSc in Portfolio Management.

Modeling of Clean Energy Markets and Valuation of PPAs   

The energy transition from fossil towards renewable energy sources is a major disruption of the way energy is procured. Key stakeholder are energy intense companies that face the challenges posed by the energy transition and the general goal of decarbonization. Looking ahead, generation capacity will be dominated by fluctuating renewable energies such as wind, solar and hydropower, which will lead to increased uncertainty in market prices. 

As feed-in-tariffs are phasing out, we see a significant growth in the use of power purchase agreements (PPAs) for renewable energy generation. PPAs are one way to manage the risk arising from uncertainty about future market prices, as they lock in future energy at a stable more predictable price for a long time period. In order to manage the risk effectively with PPAs, precise pricing and risk assessment of PPAs is essential. 

We will present an overview on PPAs including typical contract structures, as well as a discussion on energy market modeling for the purpose of PPA pricing. Moreover, we show how linear PPAs are priced in practice and give an insight into our current work on spot price models and their calibration in the context of non-linear PPA valuation. 


Martin Schlüter is a consultant for quantitative finance at the financial engineering group of Deloitte Germany. His current work is centered around the development of stochastic models for the pricing of power purchase agreements. He received his PhD in electrical engineering in 2021 from the Technical University Dresden, where his research focused on stochastic models and statistical signal processing for wireless communication systems. 

Merlin Rulff is a working student and future consultant for quantitative finance at the financial engineering group of Deloitte Germany. He is currently writing his master’s thesis on the development of stochastic spot price models for the pricing of power purchase agreements at the Christian-Albrecht-University of Kiel in quantitative finance.

Dealing with Multi-Currency Inventory Risk in FX Cash Markets

In FX cash markets, market makers provide liquidity to clients for a wide variety of currency pairs. Because of flow uncertainty and market volatility, they face inventory risk. To mitigate this risk, they typically skew their prices to attract or divert the flow and trade with their peers on the dealer-todealer segment of the market for hedging purposes. This paper offers a mathematical framework to FX dealers willing to maximize their expected profit while controlling their inventory risk. Approximation techniques are proposed which make the framework scalable to any number of currency pairs. 

Olivier Guéant is Professor of Applied Mathematics at Université Paris 1 Panthéon-Sorbonne and Adjunct Professor of Quantitative Finance at ENSAE. He leads the team “Modélisation Financière” at the Centre d’Economie de la Sorbonne (a group of 8 researchers and around 10 PhD students). His research interests are mainly related to optimal execution and market making.

In particular he developed cutting-edge models that are used by dealers on OTC markets (notably in FX and corporate bonds markets). He was awarded the Rosemont-Demassieux Prize for his PhD on mean field games in 2010 and the EIF/FBF prize for the best paper in finance in 2016 along with Charles-Albert Lehalle.

Post-Libor interest rate markets

Overnight rates, such as the SOFR (Secured Overnight Financing Rate) in the US, play a central role in the current reform of interest rate benchmarks. A striking feature of overnight rates is the presence of jumps and spikes occurring at predetermined dates, as a result of monetary policy interventions and liquidity constraints. This corresponds to stochastic discontinuities (i.e., discontinuities occurring at ex-ante known points in time) in the dynamics of overnight rates. In this work, we propose a term structure modelling framework in the presence of overnight rates and characterize absence of arbitrage in a generalised Heath-Jarrow-Morton (HJM) setting. By extending the classical short-rate approach to the case of stochastic discontinuities, we develop a tractable setup driven by affine semimartingales. In this context, we show that simple specifications allow to capture stylized facts of the jump behavior of overnight rates. In a Gaussian setting, we provide explicit valuation formulas for bonds and caplets. Finally, we investigate hedging in the sense of local risk-minimization when the underlying term structures exhibit stochastic discontinuities.

This is joint work with Claudio Fontana and Zorana Grbac
