The Importance of Soft Skills in a Quantitative World
by Jeff Scott: Founder and CEO, Section 810 Communications, LLC,

Quantitative finance often requires substantial “hard skills”–programming, machine learning, data science, AI.  But what about the “soft skills” required to collaborate with others, obtain buy-in for ideas, and lead cross-functional teams?

This fast-paced workshop will highlight the importance of these skills within the industry.  Attendees will learn:

  • What the DISC personality assessment tool is and how can it improve self-awareness
  • Ways to improve communication skills to increase your influence
  • How to obtain support for your ideas
  • Steps to build effective business relationships
  • How to work with “difficult” people

Market Generators for Long Time Horizons
by Alexander Sokol: Executive Chairman and Head of Quant Research, CompatibL

Market generators are machine learning algorithms for generating realistic samples of market data when historical time series has insufficient length or gaps. While most of the recent research on market generators focused on daily time horizons, the problem of generating realistic market data samples for time horizons from 1 year to 30 years and longer has multiple applications including limit management, insurance (economic scenario generation) and macro investing.

In this presentation, we describe a family of market generators that use machine learning to generate market scenarios with accurate probability distribution over long time horizons from limited time series.

Accelerate your AI Modelling with IPUs
by Alexander Tsyplikhin: Senior AI Engineer, Graphcore

In the finance sector, the potential for innovation with advanced machine intelligence is significant. But often, new and complex models are not being fully leveraged due to latency issues and compute restraints. Enter the IPU – a completely new processing architecture designed for machine intelligence, capable of running advanced financial models up to 26x faster. Graphcore’s Alex Tsyplikhin explains how the IPU’s unique architecture can power such incredible breakthroughs – and what this means for the future of finance and trading.

What you’ll learn:

  • How the IPU is able to achieve faster financial model accelerations than other hardware available on the market
  • How to use IPUs for financial modelling training and inference
  • Insights into advanced models, use cases and IPU benchmarks

Chebyshev Tenors + Machine Learning: applications to Dynamic Sensitivities, Counterparty Risk on exotics and FRTB
by Ignacio Ruiz: Founder & CEO & Mariano Zeron: Head of Research and Development, MoCaX Intelligence

The computation of risk metrics poses a huge computational challenge to banks. Many different techniques have been proposed in the last few years to try and tackle the problem. Chebyshev Tensors are a very powerful function approximator, but suffer from the curse of dimensionality, hence their use, being useful in many cases, is still somewhat constrained.

In this presentation we show how by incorporating Machine Learning flavoured techniques to the building of Chebyshev Tensors, the curse of dimensionality can be side-stepped, and hence a substantial range of pricing and sensitivity functions can be approximated with high accuracy and fast computation, to accelerate risk calculations substantially. In this way several risk calculations can be enhanced by this method. We illustrate the power of this technique through numerical results obtained in the calculation of Dynamic Sensitivities and its immediate side product, Dynamic Initial Margin. We also touch on applications for Counterparty Risk on exotics and IMA-FRTB.

  • Introduction to the pricing problem in risk calculations
  • Mathematical properties of Chebyshev Tensors
  • Tensor Extension Algorithm: borrow ideas from Machine Learning to overcome the curse of dimensionality
  • Numerical examples
    • Dynamic Sensitivities
    • Dynamic Initial Margin
    • Counterparty Risk on exotics and IMA-FRTB

Differential Machine Learning: the Shape of Things to Come
by Antoine Savine: Chief Quantitative Analyst, Danske Bank & Brian Norsk Huge: Chief Quantitative Analyst, Danske Markets

Brian Huge and Antoine Savine will present their paper ‘Differential Machine Learning: the Shape of Things to Come’ published in the October 2020 issue of Risk Magazine, where they combine automatic adjoint differentiation (or AAD) with modern machine learning to learn fast, accurate pricing and risk approximations for arbitrary Derivatives transactions or trading books, in the context of arbitrary stochastic models, effectively resolving computation bottlenecks of risk reports and capital regulations. The presentation explains the main ideas of the paper and concludes with a demo in a production environment.


Adding Optionality 
by Peter Carr: Professor and Dept. Chair of FRE Tandon, New York University


Risk-neutral pricing of European vanilla options amounts to a selection of the risk-neutral PDF of the underlying. When the price of the underlying security is real-valued, the most common choice of PDF is normal. We motivate the use of a logistic distribution as an alternative on both theoretical and empirical grounds. We provide supporting continuous-time and discrete-time martingales and use them to value some path-dependent options. In particular, we show how to price both an American call on a dividend-paying security and a naturally arising Bermudan-style option in closed form.

  • Why be normal?
  • Entropic motivations for logistic distribution
  • Supporting martingales
  • Closed-form pricing of American and Bermudan options

General Stochasic Volatility - New models, classical (PDE, MC) and modern numerical methods (NN)
by Jörg Kienitz: Partner, Quaternion Risk Management


In this talk we introduce General Stochastic Volatility models, especially new SABR/ZABR type models. We outline methods for approximating option prices using Finite Difference methods and/or approximation formulas. We place the research into the existing context and show numerical examples. Furthermore, we consider another approach based on neural networks. Pricing and calibration is considered. In particular we introduce the CV (control variates) method for our General SV models. Finally, we consider generative methods in this set-up.


KVA x 2
by Matthias Arnsdorf: Global Head of Counterparty Credit Risk Quantitative Research, J.P. Morgan

In this talk we try to answer two questions:

  • Should KVA be part of derivatives valuation? If so, what are its properties?
  • Does a change in capital requirements have an impact on shareholder value and hence lead to a KVA?

In exploring these questions we find:

  • There are two distinct KVA quantities that can be defined.
  • KVA1 is a result of market incompleteness and captures the value of unpriced risk. This should be considered integral to an assets value.
  • KVA1 is not sensitive to changes in capital levels but is risk based.
  • In many cases of interest, KVA1 has implicitly already been incorporated in valuation and no additional adjustment is required.
  • KVA2 is compensation for shareholder losses due to changes in a firms leverage. This represents a “Transfer of Wealth” between shareholders and creditors similar to FVA.
  • KVA2 is proportional to marginal changes in capital levels. However,  the effective cost of this capital is the firms junior funding rate and not the return-on-equity.

KVA Under IMM and Advanced Approaches
by Justin Chan: Head of Product Management, Risk, FIS

The two largest components of Capital Valuation Adjustment (KVA) are the costs of Counterparty Credit Risk (CCR) and CVA capital. For a bank using the most advanced capital models – Internal Models Method for CCR and the incoming SA-CVA capital –an accurate KVA involves forward simulating expected exposures (EE) over the lifetime of the portfolio – potentially a Monte Carlo in a Monte Carlo. We present a practical regression-based solution.

  • Simulating EE: from regulatory stressed real-world measure to market implied measure
  • A comparative study of regression vs brute force nested Monte Carlo
  • SA-CVA: extending from simulating forward EE to simulating forward CVA sensitivities

Interest Rates Benchmark Reform and Options Markets
by Vladimir Piterbarg: MD, Head of Quantitative Analytics and Quantitative Development, NatWest Markets

We examine the impact of interest rates benchmark reform and upcoming Libor transition on options markets. We address various modelling challenges the transition brings. We specifically focus on the impact of the clearing houses’ discounting switch on swaptions, and the consequences of Libor transition on Libor-in-arrears swaps, caps, and range accruals as typical representatives of a very wide range of Libor derivatives.
