LTI@UniTO seminars | Christopher Polk, May 2nd and Andrea Tamoni, May 3rd @12.00
by Luca Regis 24 Jun '23

24 Jun '23

Dear Colleagues, it is my pleasure to invite you to the following two seminars in Quantitative Finance, organised by LTI@UniTO (www.carloalberto.org/lti) and Collegio Carlo Alberto (CCA), which will take place at CCA in Torino and can be followed via Zoom. At the event page link you can find the paper, the zoom link to attend online and a button to add the event to your calendars. ------------------------------------------------------------------------------------------- May 2nd @ 12.00 Speaker: Christopher Polk (LSE) Title: The Day Destroys the Night, Night Extends the Day: A Clientele Perspective on Equity Premium Variation Abstract: We decompose market returns into their overnight and intraday components, which dramatically improves equity premium forecasts. Past smoothed overnight market returns strongly negatively forecast subsequent close-to-close returns (quarterly R2 of over 14%), primarily through intraday mean reversion. In contrast, past smoothed intraday market returns strongly positively forecast subsequent overnight returns; this partially-offsetting effect explains PE’s relatively poor forecasting ability (R2 only 3%). Our decomposition also resurrects the conditional CAPM: If we allow market betas to vary with past smoothed overnight returns, the four Fama-French factors’ alphas decrease on average by 84%. We interpret these return patterns through a clientele perspective. First, individual investor expectations and consumption growth strongly positively forecast overnight market returns, while intermediary risk tolerance strongly negatively forecasts intraday market returns. Second, aggregate cash-flow news occurs primarily intraday and is positively (negatively) correlated with revisions in expected future overnight (intraday) returns. Finally, while the Tech boom, Covid crash/rebound, and patterns in meme stocks were primarily driven by overnight returns, the Global Financial Crisis was mostly an intraday phenomenon.

We find that 401(k) fund and stock ownership are the most important variables, after size, explaining fund demand for stocks, with a one standard deviation increase in 401(k) ownership leading to 15-30% increase in stock demand. Funds managing a larger fraction of 401(k) assets tilt their portfolios toward winners, high beta and long duration stocks, outperforming their benchmarks. This investment behavior has important implications for security pricing and generate a feedback effect if pension flows respond positively to relative fund returns. Lastly, we estimate the equilibrium price impact of a change in 401(k) ownership to be positive and increasing over time, consistent with the shift from active to passive investing.

announcement Vienna WPI Workshop- looking for contributed speakers
by Viktoria Schildhammer 05 Jun '23

05 Jun '23

Dear colleagues, We would like to announce the following workshop “Stochastics, Statistics, Machine Learning and their Applications to Sustainable Finance and Energy Markets” taking place at the Wolfgang Pauli Institute (WPI) in Vienna, Austria from the 11.09.2023-14.09.2023 (https://wpi.univie.ac.at/). The workshop aims at bringing together an interdisciplinary group of leading researches with interest in stochastic methods for sustainable finance and energy markets. Particular emphasis will be given to Environmental Social Governance (ESG) finance, climate/weather modeling, optimal control problems and optimal contract theory e.g. in view of fostering renewable energy sources The workshop starts on September 11, 2023, with two graduate courses held by Roxana Dumitrescu and Matheus Grasselli in the areas of green finance, climate modeling, renewables in energy markets and optimal control. The graduate courses are meant for Phd and advanced Master students and roughly correspond to 1 ECTS. A background in probability theory, applied stochastic processes, and statistics is recommended. These courses are then followed by 3 full conference days. The goal is to provide a platform for exchanging new ideas among different research communities and initiate interdisciplinary collaborations. In particular a dedicated time for discussions will be scheduled on each day of the workshop. Beside the keynote speakers, there will be a limited amount of slots for contributed talks. We thus invite interested researchers including Phd students to present their recent work at the workshop. If you would like to give a contributed talk, please send the title and abstract in a plain text email to: wpi-stostaml.2023(a)univie.ac.at The submission deadline is 10.06.2023. Please also mention which days of the workshop you would be able to participate. The organizing committee will review the abstracts and will get back to you by approximately end of June to let you know if your talk has been accepted. Attending the workshop is for free, but please register via email to wpi-stostaml.2023(a)univie.ac.at The registration deadline is 01.08.2023. Please also mention which days of the workshop you would be able to participate. In case of problems / questions, please do not hesitate to send us an e-mail (wpi-stostaml.2023(a)univie.ac.at). We are looking very much forward to welcoming you in Vienna in September!

seminario Federico Sau (Sapienza, 6 Giugno)
by Matteo Quattropani 29 May '23

29 May '23

Salve a tutti, Segnalo il seguente seminario, che avrà luogo Martedì 6 Giugno alle ore 14:00 in Sala di Consiglio (Dipartimento di Matematica, Università La Sapienza): Speaker: Federico Sau (Università di Trieste) Title: Spectral gap of the symmetric inclusion process. Abstract: In this talk, we consider the symmetric inclusion process on a general finite graph. Our main result establishes universal upper and lower bounds for the spectral gap of this interacting particle system in terms of the spectral gap of the random walk on the same graph. In the regime in which the gamma-like reversible measures of the particle system are log-concave, our bounds match, yielding a version for the symmetric inclusion process of the celebrated Aldous' spectral gap conjecture --- originally formulated for the interchange process and proved by Caputo, Liggett and Richthammer (JAMS 2010). Finally, by means of duality techniques, we draw analogous conclusions for an interacting diffusion-like unbounded conservative spin system known as Brownian energy process, which may be interpreted as a spatial version of the Wright-Fisher diffusion with mutation. Based on a joint work with Seonwoo Kim (SNU, South Korea). Saluti, Matteo Quattropani

Postdoc positions in Pisa
by Marco Romito 25 May '23

25 May '23

Good morning I would like to advertise the call for two two-years post-doc positions at the Department of Mathematics at the University of Pisa on general subjects of mathematics. The deadline is June 19, 2023 at 1pm CEST. The call, both in italian and english, as well as instructions for applications, can be found here (one link per position): https://bandi.unipi.it/public/Bandi/Detail/8b0389fe-808f-4152-8a44-02380d65… https://bandi.unipi.it/public/Bandi/Detail/dfe05072-6753-434a-8551-65f50969… We strongly encourage applications of students interested in probability. Applications are per-call, and we recommend interested applicants to apply to both calls. The research interests of our probability group here in Pisa include: stochastic evolutions (e.g. stochastic partial differential equations, regularization by noise, stochastic fluid dynamics), probabilistic methods in machine learning (e.g. learning dynamics for neural networks), variational problems in commutative and non-commutative setting (e.g. quantum probability, random optimal transport, Malliavin calculus), stochastic processes for chemical reactions networks (e.g. propagation of chaos, large deviations). See also our webpage: https://www.dm.unipi.it/research/probability-and-mathematical-statistics/ Do not hesitate to contact me or the other members of the group for further information. best regards m.
