*“Do jumps matter in Realized Volatility modeling and forecasting?
Empirical evidence and a new model”*
*Massimiliano Caporin, University of Padova*
*Abstract*: Building on an extensive empirical analysis I investigate
the relevance of jumps and signed variations in predicting Realized
Volatility. I show that properly accounting for intra-day volatility
patterns and staleness sensibly reduces the identified jumps. Realized
Variance decompositions based on intra-day return size and sign improve
the in-sample fit of the models commonly adopted in empirical studies. I
also introduce a novel specification based on a more informative
decomposition of Realized Volatility, which offers improvements over
standard models. From a forecasting perspective, the empirical evidence
I report shows that most models, irrespective of their flexibility, are
statistically equivalent in many cases. This result is confirmed with
different samples, liquidity levels, forecast horizons and possible
transformations of the dependent and explanatory variables.

*“V-shapes”*
*Roberto Renò, University of Verona*
*Abstract*: An insidious form of market inefficiency, by which prices
lose their informativeness and wealth is distributed arbitrarily,
translates into V-shapes, that is sudden changes of the sign of the
price drift. We use this insight to develop a new tool for the detection
of reverting drift, the V-statistic. We apply this tool to (i) quantify
the extent of this kind of market inefficiency in the U.S. stock market
during the Covid-19 pandemic; and (ii) show the harmful consequences of
V-shapes on financial stability by estimating the huge loss suffered by
Italian taxpayers (0.45B euros) in May 2018, when a transient crash hit
the secondary bond market during a Treasury auction.
/Joint with Maria Flora./

Dear Colleagues,
We would like to invite you to the following Probability seminar
that will take place on March 26 at 14.30 by the zoom platform.

Speaker: Luisa Andreis (Università di Firenze)
Title: Phase transitions in sparse random graphs and coagulation processes
26 MARCH (Friday) - 14:30 zoom link: TBA
available on the webpage https://www.math.unipd.it/~bianchi/seminari/ )
Abstract:
Sparse inhomogeneous random graphs are a natural generalization of the
well-known Erdos Rényi random graph, where vertices are characterized by a
type and edges are independent but distributed according to the type of the
vertices that they are connecting. These graphs undergo a phase transition
in terms of the emergence of a giant component exactly as the classical
Erdos Rényi model. In this talk we will present an alternative approach,
via large deviations, to prove this phase transition. This allows a
comparison with the gelation phase transition that characterizes
coagulation processes and the phase transition of condensation type
emerging in several systems of interacting components. This is an ongoing
joint work with Wolfgang Koenig (WIAS and TU Berlin), Robert Patterson
(WIAS) and Heide Langhammer (TU Berlin).

Tomorrow's speakers in the One World Probability Seminar are
(Note: all times are in UTC. *Due to time changes, you should check what
that translates to in your location*)
------------------------------------------------
(14:00-15:00 UTC) Speaker: Yvik Swan (Université Libre de Bruxelles)
Title: Stein’s density approach
Abstract: Stein’s method is a collection of tools allowing to obtain
explicit (non-asymptotic) bounds on discrepancies between probability
distributions. The heart of the method is a so-called “Stein operator”, and
it is the objective of this talk to present the basic theory behind these
operators, and also cover some applications of the theory. After presenting
the general theory (with a focus on Stein’s so-called density approach), we
will give details on the 1-dimensional case, hereby connecting with
classical topics such as Covariance and Poincaré inequalities.
The material covered in the talk is closely related to work with Marie
Ernst, Christophe Ley, Guillaume Mijoule and Gesine Reinert.
(15:00-16:00 UTC) Speaker: Gesine Reinert (University of Oxford)
Title: Stein’s method for multivariate continuous distributions and some
statistical applications
Abstract: Stein’s method can be viewed as employing an operator which
action characterises a distribution uniquely, relating this operator to
test functions through a Stein equation, and comparing distributions by
taking expectations of this Stein equation. Using the density approach for
Stein’s method, this talk will present a general framework for Stein’s
method for multivariate continuous distributions.
For any given nontrivial distribution this approach leads to an infinite
collection of Stein characterisations which can be used to assess
distributional distances. We shall apply this framework to compare
posterior distributions which arise from the same model but using different
priors.
Using the notion of a weak Stein equation, bounds on distributional
distances based on Lipschitz test functions are obtained if the
distribution admits a Poincare’ constant. This result will be used to
compare copulas.
Finally, using the notion of a Stein kernel, we shall extend Stein’s
shrinkage results and Stein’s Unbiased Risk Estimate (SURE) to non-Gaussian
distributions.
This talk is based on joint work with Max Fathi, Larry Goldstein, Adrien
Saumard, and of course Yvik Swan.
