A Talk from Annual Conference 2024

This presentation introduces the application of quantum-inspired Tensor Networks in quantitative finance, focusing on their ability to handle high-dimensional data efficiently. We explore the relationship between quantum computing and Tensor Networks, and how these methods can enhance machine learning models. Specific attention is given to the use of Tensor Network machine learning in derivatives pricing, where they can offer improved accuracy and computational efficiency. By leveraging these techniques, Tensor Networks have the potential to transform both machine learning and financial modeling.

It is argued that in a variety of ways randomness plus path continuity is a strange and almost contradictory request. Attention is then turned to discontinuous continuity approximations with financially relevant results being delivered by finite activity processes of finite variation. The CGMY model is employed to decompose stochastic volatility into stochasticity in speed, scale and the degree of continuity. The bilateral gamma model is used to relate risk premia to the degree of continuity as measured by the speed and scale coefficients. Rescaling mechanisms are introduced to recover return distributions from option prices that are useful for investment analysis.

A Talk from Annual Conference 2024

Market generators are a rapidly evolving class of models that simulate financial market behavior using neural networks. These deep learning models learn the underlying distribution of financial data and generate synthetic market scenarios, offering a powerful alternative to classical stochastic models. The expression “Market Generator” only entered the vocabulary of financial modelling around 2019, but by today it has already grown into an area of its own right, with a rapidly growing number of research contributions appearing on the matter. This talk aims to unravel the evolution of the rapidly evolving landscape of generative models in Machine Learning in the context of more classical modelling techniques in finance for the evolution of stock prices but also in the context of the most recent trends of Generative AI that include LLMs.

More concretely we will present a very powerful generative model for time-series modelling: State-of-the-art performance for irregular time series generation has been previously obtained by training Neural SDEs adversarially as GANs. However typical for GAN architectures suffer from various instabilities in training. Instead, we introduce a novel class of generative models that can be trained non-adversarially, using scoring rules on pathspace based on signature kernels. Most notably this procedure permits to evaluate a corpus of paths against a single observation. But additionally, our procedure permits conditioning on a rich variety of market conditions and significantly outperforms alternative ways of training Neural SDEs on a variety of tasks including the simulation of rough volatility models, the conditional probabilistic forecasts of real-world forex pairs where the conditioning variable is an observed past trajectory. Moreover, our framework can be easily extended to generate spatiotemporal data, including the mesh-free generation of limit order book dynamics.

This talk will explore how certain aspects of the green shift may potentially lead to “green inflation,” driven by money printing and investment in less effective energy production methods, especially in an environment where populism is prevalent. Additionally, we will briefly discuss our views on quantum computers, including quantum gravity computers, and their potential implications for finance and the society.

We develop a model based on time changed Lévy processes and study its ability of reproducing the joint S&P500/VIX implied volatility smiles and the VIX futures prices – a problem known in the literature as the ‘joint calibration problem’. The model admits semi-analytical characteristic functions for the key quantities, and therefore efficient Fourier based pricing schemes can be deployed. We focus on a specification of the proposed general setting which uses purely discontinuous processes. Results from the application to market data show satisfactory performances in solving the joint calibration problem, and therefore demonstrate that the class of affine processes can provide a workable fit.

A Talk from Annual Conference 2024

Twenty five years ago, several authors proposed to model the forward interest rate curve as an elastic string along which idiosyncratic shocks propagate, accounting for the peculiar structure of the return correlation across different maturities. In this paper, we revisit the specific “stiff” elastic string field theory of Baaquie-Bouchaud 2004 in a way that makes its micro-foundation more transparent. Our model can be interpreted as capturing the effect of market forces that set the rates of nearby tenors in a self-referential fashion. The model is parsimonious and accurately reproduces the whole correlation structure of the FRC over the time period 1994-2023, with an error below 2 \%$. The dependence of correlation on time resolution (also called the Epps effect) is also faithfully reproduced within the model and leads to a cross-tenor information propagation time of a few tens of minutes. Finally, we confirm that the perceived time in interest rate markets is a strongly sub-linear function of real time. In fact, our results are fully compatible with hyperbolic discounting, in line with the recent behavioural Finance literature.

A Talk from Annual Conference 2024

Polymodels are a statistical analysis technique for dynamic objects evolving within an environment, which is dynamic as well. Both the object and the environment are described by time series. In a financial context, the object is an asset, a fund, a portfolio, anything that can represent an investment, while the environment is made of variables or “factors” that describe the state of the market. Polymodels provide the individual response of the object to every single variable of the environment, together with a reliability score. These response functions being nonlinear, the fragility/antifragility properties of the object can be evaluated.

We will show how to estimate polymodels and to use them for asset selection, risk assessment and portfolio construction, as well as recent research on the risk of hedge funds. Our focus is the fragilities of those prone to blow up at the time of crisis, despite impeccable track record.
