*March 1, 2021 | 17:00-18:00*
*“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.

Dear Colleagues,
LTI@UniTO and CCA are pleased to invite you to the following webinar in Quantitative Finance by *Fabio Trojani *(University of Geneva) which will take place on March, 24th at 12 via Zoom:
*Title:*“Smart Stochastic Discount Factors”
*Abstract:*We propose a novel no-arbitrage framework, which exploits convex asset pricing constraints to study the properties of investors’ marginal utility of wealth or, more generally, Stochastic Discount Factors (SDFs). We establish a duality between minimum dispersion SDFs and suitable penalized portfolio selection problems, building the foundation for a nonparametric characterization of the feasible tradeoffs between a SDF’s pricing accuracy and its comovement with systematic risks. Empirically, we find that a minimum variance correction of a CAPM–SDF produces a Pareto optimal tradeoff. This Pareto optimal SDF only depends on two economically distinct risk factors: A market factor and a minimum variance excess return factor, which optimally bounds the aggregate mispricing of risks unspanned by market risk.
