The fractional Brownian motion in volatility modeling
Elisa Alòs (Universitat Pompeu Fabra, Barcelona)
This talk focuses on the properties of volatilities driven by the fractional Brownian motion (fBm) or
related processes. In particular, we study the shortend behaviour of the atthemoney level, skew and
curvature of fractional volatilities, and we see how this behaviour is more consistent with real market
data.
Rough volatility: Fact or artefact?
Rama Cont (University of
Oxford)
Based on joint work with Purba Das
We investigate the statistical evidence for the use of "rough" fractional processes with Hurst exponent H<0.5 for the modeling of volatility of financial assets, using a modelfree approach. We introduce a nonparametric method for estimating the roughness of a function based on a discrete sample, using the concept of normalized pth variation along a sequence of partitions. We investigate the finite sample performance of our estimator for measuring the roughness of sample paths of stochastic processes using detailed numerical experiments based on sample paths of fractional Brownian motion and other fractional processes. We then apply this method to estimate the roughness of realized volatility signals based on highfrequency observations. Detailed numerical experiments based on stochastic volatility models show that, even when the instantaneous volatility has diffusive dynamics with the same roughness as Brownian motion, the realized volatility exhibits rough behaviour corresponding to a Hurst exponent significantly smaller than 0.5. Comparison of roughness estimates for realized and instantaneous volatility in fractional volatility models with different values of Hurst exponent shows that, irrespective of the roughness of the spot volatility process, realized volatility always exhibits "rough" behaviour with an apparent Hurst index Ĥ <0.5. These results suggest that the origin of the roughness observed in realized volatility time series lies in the estimation noise rather than the volatility process itself.
A GMM approach to estimate the roughness of stochastic volatility
Mikko Pakkanen (Imperial College London)
I present an approach to estimate log normal stochastic volatility models, including rough volatility
models, using the generalized method of moments (GMM). In this GMM approach, estimation is done directly
using realized measures (e.g., realized variance), avoiding the biases that arise from using a proxy of spot
volatility. I also present asymptotic theory for the GMM estimator, lending itself to inference, and apply
the methodology to Oxford–Man realized volatility data. This presentation is based on joint work with Anine
Bolko, Kim Christensen and Bezirgen Veliyev.
PART 2 – Chaired by Knut Sølna (University of California at Irvine)
Quadratic Gaussian models: Analytic expressions for pricing in rough volatility models
Eduardo Abi Jaber (Université Paris I)
Stochastic models based on Gaussian processes, like fractional Brownian motion, are able to reproduce
important stylized facts of financial markets, such as rich autocorrelation structures, persistence and
roughness of sample paths. This is made possible by virtue of the flexibility introduced in the choice of
the covariance function of the Gaussian process. The price to pay is that, in general, such models are no
longer Markovian nor semimartingales, which limits their practical use. We derive explicit analytic
expressions for Fourier–Laplace transforms of quadratic functionals of Gaussian processes. Such
analytic expression can be approximated by closed form matrix expressions stemming from Wishart
distributions. We highlight the applicability of such results in the context of rough volatility modeling:
(i) fast pricing and calibration in the (rough) fractional Stein–Stein model; (ii) explicit solutions for
the Markowitz portfolio allocation problem in a multivariate rough Stein—Stein model.
Efficient inference for large and highfrequency data
Alexandre
Brouste (Université du Maine)
Although a lot of attention has been paid to the highfrequency data due to their increasing availability
in different applications, several statistical experiments under the highfrequency scheme remain not fully
understood. For instance, at high frequency, the variance and the Hurst exponent for the fractional Gaussian
noise (fGn) or the scale and the stability index for the stable Lévy process are melting. Weak LAN property
with a singular Fisher information matrix was obtained for the fGn and for the stable Lévy
process.
Due to this singularity, no minimax theorem can be applied and it has been unclear for a long time whether the maximum likelihood estimator (MLE) possesses any kind of asymptotic optimality property. More recently, we established a nonsingular LAN property for the fGn and for the stable Lévy process making it possible to define the asymptotic optimality in these statistical experiments.
The LAN theory does not directly provide the construction of efficient estimators. In regular statistical experiments, the MLE generally achieves optimality. Nevertheless, its computation is time consuming, and alternatives should be found to handle big or highfrequency datasets available in the fields of insurance and finance. In this direction, the Le Cam onestep estimation can be proposed in the aforementioned statistical experiments (and in others).
Timeinhomogeneous Gaussian stochastic volatility models: Large deviations and super
roughness
Archil Gulisashvili (Ohio University)
The talk concerns timeinhomogeneous stochastic volatility models in which the volatility is described by
a nonnegative function of a Volterra type continuous Gaussian process that may have very rough sample
paths. We prove smallnoise large deviation principles for the logprice process in a Volterra type Gaussian
model under very mild restrictions. These results are used to study the smallnoise asymptotic behavior of
binary barrier options, exit time probability functions, and call options.

FROM MICROSCOPIC MODELS TO ROUGH MACROSCOPIC MODELS
Visioconference
SLOAN CONFERENCE: Price regimes
Organized with École Polytechnique and the University of California at Irvine
In recent years, nonMarkovian modeling has received a lot of attention in pure and applied financial modeling. It is of fundamental and practical interest to understand how such nonMarkovian, or fractional behavior, as observed on a macroscale, can arise as a result of stated models on the microscale. Such analysis bears similarities, but also differences, to the analysis of physical systems from a scaling limit perspective. This conference will present some aspects of the process of understanding rough macroscale behavior as a result of certain microscopic dynamics.
Program
Quadratic Hawkes processes: A microfoundation for rough volatility models?
JeanPhilippe Bouchaud (Capital Fund Management/École polytechnique)
We discuss a natural generalization of the Hawkes processes that accounts for a feedback from past price trends and volatility onto current activity. The model naturally explains the powerlaw nature of price returns and the violation of time reversal invariance. It can be extended in various directions, in particular to model the activity in the order book and the occurrence of liquidity crises.
From noarbitrage to rough volatility via market impact
Mathieu Rosenbaum (École polytechnique)
Market impact is the link between the volume of a (large) order and the price move during and after the execution of this order. We show that under noarbitrage assumption, the market impact function can only be of a powerlaw type. Furthermore, we prove that this implies that the macroscopic price is diffusive with rough volatility, with a onetoone correspondence between the exponent of the impact function and the Hurst parameter of the volatility. Hence, we simply explain the universal rough behavior of the volatility as a consequence of the noarbitrage property. From a mathematical viewpoint, our study relies, in particular, on new results about hyperrough stochastic Volterra equations.
Modeling rough covariance processes
Christa Cuchiero (University of Vienna)
The rough volatility paradigm asserts that the trajectories of assets’ volatility are rougher than Brownian motion, a revolutionary perspective that has changed certain persistent views of volatility. It provides via stochastic Volterra processes a universal approach to capture important features of time series and option price data, as well as microstructural foundations of markets. We provide an infinite dimensional point of view on stochastic Volterra processes, which makes it possible to dissolve a generic nonMarkovanity of the atfirstsight naturally low dimensional volatility process. This approach makes it possible to go beyond the univariate case and to treat multivariate rough covariance models, in particular of affine and Wishart type, for more than one asset.

CONFERENCE SUMMARY
What can we say about the evolution of oil and gas prices?
The conference will address this issue by:
(i) presenting tools that can be used to describe the complex multiscale structures of energymarket price data;
(ii) discussing the possible mechanisms behind these regime shifts;
(iii) considering the possible implications for hedging and risk assessment.
A special focus will be put on the evolution of prices since the end of 2014.
The observation of market price fluctuations sometimes reveals behaviors that cannot be well captured by standard models based on discretetime random walks or continuous diffusion. In standard models, the return fluctuations of a risky asset are driven by Brownian motion, giving independent Gaussian returns. It has become clear that oil and gas price data vary at different interconnected scales, slow or fast: they have a complicated multiscale structure that, moreover, may vary over time. Timefrequency analysis can be used to identify the main features of these variations and, in particular, the regime shifts. The analysis derives from a waveletbased decomposition, a special decomposition of a signal in timefrequency components, and the associated scale spectrum. The joint estimation of the local Hurst coefficient (an index of smoothness) and volatility is the key to detecting and identifying regime shifts and changes in the oil price. For the first time since 1986, "persistence" processes of unprecedented force occurred between the end of 2014 and 2016, opening up a new period.

The work of Kiyosi Itô and the Japanese school of stochastic processes that he founded is exceptional both in its beauty as pure mathematics and in the insights it has provided in biology, chemistry, quantum physics, electrical engineering, and finance. As the International Mathematical Union attested in awarding Itô its first Carl Friedrich Gauss prize in 2006, his work ranks as part of the world’s cultural heritage.
From its outset, however, Itô’s work has stood in a special relationship to French mathematicians. The first citation in Itô’s published work, in fact, the first sentence of his first article, was to Paul Lévy’s, Théorie de l’addition des variables aléatoires . As Itô later wrote, he learned stochastic processes from this book. His goal was to make fully mathematical the beautiful structure the book depicted, and he succeeded. It is often said that other French mathematicians understood Lévy only after Itô had explained his contribution. Thirty years later, in the 1970s, Itô was still interacting with French mathematicians, embracing and further developing PaulAndré Meyer’s semimartingalebased version of Itô’s theory of stochastic integration. Today, French mathematicians remain among those most keen to develop the applications of Itô’s calculus in physics and finance.
This conference examines Itô’s legacy from the perspective of this relationship. Is the theory of stochastic processes now truly a theory of sample paths as Lévy had envisioned? What has made Lévy processes and Itô’s understanding of stochastic integration so fruitful for applications in physics and finance? Where is Itô’s legacy taking us today?
