A Dynamic Model of Central Counterparty Risk
We introduce a dynamic model of the default waterfall of derivatives CCPs and propose a risk sensitive method for sizing the initial margin (IM), and the default fund (DF) and its allocation among clearing members. Using a Markovian structure model of joint credit migrations, our evaluation of DF takes into account the joint credit quality of clearing members as they evolve over time. Another important aspect of the proposed methodology is the use of the time consistent dynamic risk measures for computation of IM and DF. We carry out a comprehensive numerical study, where, in particular, we analyze the advantages of the proposed methodology and its comparison with the currently prevailing methods used in industry.

Symposium on Computational Finance:
Building and Calibrating Multivariate Sato Models with Linear Dependence
The increased trading in multi-name financial products requires the development of state-of-the-art multivariate models. These models should be computationally tractable and at the same time flexible enough to explain the stylized facts of asset log-returns and of their dependence structure. In this talk, we propose a general framework for multivariate models characterized by independent and time-inhomogeneous increments. This is done by space-scaling linear combinations of independent self-decomposable random variables, leading to multivariate models of the Sato type. Dependence between the assets is introduced linearly by considering for each asset both an idiosyncratic and a systemic risk factor. As an example, we elaborate the case of VG and difference of Gamma distributed risk factors and calibrate the resulting multivariate models on a basket of three major stocks included in the DJIA. The calibration is performed on a wide set of quoting days exhibiting different levels of market fear, using two different calibration methodologies.

Symposium on Computational Finance:
Bayesian Non-Parametric Approach to Joint and Last Survivor Annuities Pricing
In this paper we propose a new modeling approach to annuities pricing based on Bayesian non-parametric, focusing mainly on the joint and last survivor products. Differently from the other works in the literature about annuity pricing, our methodology doesn’t require any specifc assumption on the functional form of the marginal and joint distribution. Exploiting the updating mechanisms intrinsic in the Bayes theorem the model can learn autonomously from the data and can adapt to changes in the mortality hence minimizing the misspecifcation risk. Additionally, if prior beliefs about the dependence structure and/or the marginal survivorships are present, we are going to show how these can be easily embedded in the model. Thanks to this features the resulting annuity price will be a combination of the analyst expectations and the information embedded in the data. Empirically, the model can be calibrated via simulation-based techniques, like Markov Chain Monte Carlo. In particular we propose a simple estimation via Gibbs-Sampling. Using the dataset of Frees et al. (2016) as well as customized data, we discuss how the new model can be used in practice, also showing how different priors affect the calibration. Finally we compare our results with copula based pricing models which can be considered the gold Standard of the present methodologies.

Symposium on Computational Finance:
Model Reduction Techniques for Finance
In this work, we consider model reduction techniques for finance motivated problems, e.g., option pricing or optimal trading. In the event that our specific problem does not admit a closed-form expression, one needs numerical methods to gain information about the solution. In many applications, we have a parameter-dependent setting, where the same task needs to be solved multiple times for incoming market data.
For each parameter, we want to achieve a numerical solution with sufficient accuracy. Thus, we need fine discretizations, which can resolve in long computation times. Therefore, we use the reduced basis method (RBM) to derive a reduced model, in which we can evaluate solutions for each parameter with less computational effort.
In particular, we consider the intraday trading of electricity and derive a parametrized Hamilton-Jacobi-Bellman (HJB) equation for this setting. Our aim is to find an optimal strategy within the short trading time using the most recent information of the market. Then, we analyze the reducibility with the RBM of this parametric HJB setting. We comment on the (to our knowledge) only existing approach for this problem and provide numerical investigations for our method.
Silke Glas is a research assistant at Ulm University. Her current research is about model reduction for Hamilton-Jacobi-Bellman (HJB) equations resulting from intraday trading of electricity. Particularly, she is interested in HJB equations, for which the control is not representable by first order conditions.
She is doing her PhD in a joint project with University of Duisburg-Essen and Ulm University under the supervision of Prof. Dr. Karsten Urban and Prof. Dr. Rüdiger Kiesel. The topic of her PhD is model reduction for variational inequalities, motivated by the calibration of American Options.

Machine Learning Applied to SLV Calibration
We calibrate local stochastic volatility using the particle method developed by [Guyon, Henry-Labordere]. A critical step in this method is an estimation of the conditional expectation of the stochastic volatility process, given the realized spot. We reformulate this estimation as a non-linear regression at each time-step of the discretized process, which allows us to apply machine learning (ML) techniques. We review appropriate ML techniques, compare results and Performance.

An HJM-type stochastic spread Model – Theory and Implementation
We present an interest rate model incorporating stochasticity on spreads on the OIS rate, employing a Trolle–Schwartz model for the OIS rate and a Trolle-Schwartz commodity model for the spreads, both facilitating stochastic volatility. We describe the model’s basic properties and derive necessary drift conditions following the works of Grbac and Rungaldier to ensure arbitrage-free-ness under the OIS numéraire. Moreover, we provide a simulation scheme for the hypothetical spread bonds and derive a semi-closed-form solution based on Fourier pricing methods for bond options on spread-bearing zero bonds.

Approximating MVA along Low-Dimensional State Spaces
The Initial Margin Valuation Adjustment (MVA) is the present value of the opportunity and funding costs generated by future initial margin amounts. Computing MVA requires long-term risk neutral simulations of future initial margin requirements. In this talk, I present a novel method for approximating ISDA SIMM based MVA. It consists in projecting the SIMM measures from high-dimensional risk factor spaces to lower-dimensional subspaces parametrized by model state variables, calibrated model parameters or explanatory variables. ISDA SIMM based MVA can thus be approximated in terms of future sensitivities with respect to this more accessible and lower-dimensional vector of model-specific risk vectors. This projection method uses principal components analysis, and it fits in naturally with American Monte Carlo techniques.

Corridor Variance Swap Spread
Two-underlying corridor variance swap spreads have become very popular in recent years. Dealers use them to hedge the vega exposure of their retail structured product flows (autocallable and Uridashi notes); For investors they provide attractive opportunities to capture the relative variance risk premium between different markets. However currently there is very limited literature available. In this talk we examine the use of two-underlying corridor variance swap spreads from both sell-side and buy-side perspectives, and investigate different valuation approaches, especially the impact of stochastic volatility, correlations and quanto effect.

Simulating Hedge Fund Strategies: Generalising Fund Performance
We apply a multipath search algorithm to map hedge fund performance to a set of market indices. We show that a carefully selected set of market indices is sufficient to capture most features of hedge fund return distributions. In a second step, we demonstrate that this mapping can be generalised to project hedge fund strategies onto the market indices. We calibrated asymmetric GARCH processes to the indices and ran out-of-sample tests for the combined model. The resulting distributions capture the downside risk of almost all hedge fund strategies in our sample set. Finally, we extend the mechanics to simulate the return distribution of portfolios of hedge funds and show that this produces a conservative estimate. The technique is well suited to assess the risk of collateralised fund obligations and other similar products.

Symposium on Computational Finance:
Quantifying Credit Portfolio Losses under Multi-Factor Models
In this work, we investigate the challenging problem of estimating credit risk measures of portfolios with exposure concentration under the multi-factor Gaussian and multi-factor t-copula models. It is well-known that Monte Carlo (MC) methods are highly demanding from the computational point of view in the aforementioned situations. We present efficient and robust numerical techniques based on the Haar wavelets theory for recovering the cumulative distribution function (CDF) of the loss variable from its characteristic function. To the best of our knowledge, this is the first time that multi-factor t-copula models are considered outside the MC framework. The analysis of the approximation error and the results obtained in the numerical experiments section show a reliable and useful machinery for credit risk capital measurement purposes in line with Pillar II of the Basel Accords.

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.

Efficient Exposure Computation by Risk Factor Decomposition
The focus of this talk is the efficient computation of counterparty credit risk exposure on portfolio level. Here, the large number of risk factors rules out traditional PDE-based techniques and allows only a relatively small number of paths for nested Monte Carlo simulations, resulting in large variances of estimators in practice. We propose a novel approach based on Kolmogorov forward and backward PDEs, where we counter the high dimensionality by a generalisation of anchored-ANOVA decompositions. By computing only the most significant terms in the decomposition, the dimensionality is reduced effectively, such that a significant computational speed-up arises from the high accuracy of PDE schemes in low dimensions compared to Monte Carlo estimation. Moreover, we show how this truncated decomposition can be used as control variate for the full high-dimensional model, such that any approximation errors can be corrected while a substantial variance reduction is achieved compared to the standard simulation approach. We investigate the accuracy for a realistic portfolio of exchange options, interest rate and cross-currency swaps under a fully calibrated ten-factor model.

Dr. Artur Sepp
Applications of Machine Learning for Volatility Trading and Asset Allocation
Most applications of quantitative trading and investing require the forecast of the future realized volatility as a key input. While there are many models for volatility measurement and forecast, the key decision is how to select the best models with the highest predicative power for a given application. I apply the methods of supervised machine learning and learning to rank for the machine-based selection of volatility models. I demonstrate applications of this framework to trading strategies in implied vs realized volatilities, to designing volatility-targeting products, and to implementing risk-based and risk-parity allocations.

Applications of the Heston Stochastic Local Volatility Model in Commodity Markets
Stochastic Local Volatility (SLV) models have become the industry standard for FX and equity markets. The local volatility extension of the popular Heston stochastic volatility model is a promising candidate within the zoo of SLV models. The Local Volatility component of the Heston SLV model allows for a natural modelling approach of the Samuelson effect, which is prevailing in commodity markets. In addition, the stochastic component assures consistent pricing over the entire volatility skew. The presentation introduces a multi-factor Heston SLV model for the forward curve dynamics in conjunction with a day-ahead process including potential spikes. An efficient calibration algorithm together with a fast and accurate simulation scheme allows for fast pricing of Asian averaging, multi-callable/Bermudan-style options, which are common in gas markets.
