Speaker: Prof. Dilip Madan, Robert H. Smith School of Business, University of Maryland Abstract: Strategies for selecting hedging measures that both respect certain market values of cash flows and yet maintain control on their distance from physical measures are advocated, proposed and implemented. The hedging criterion is the maximization of a conservative valuation of the […]
Speaker: Prof. Ruiqi Liu, Department of Mathematics & Statistics, Texas Tech University Abstract: This paper introduces a novel approach for estimating structural break ratios in the factor loadings of high-dimensional approximate factor models, where the breaks occur at unknown common dates and the number of factors is unknown. Our method is based on the observation […]
Speaker: Massimo Guidolin, Department of Finance, Bocconi University, Milan, Italy Abstract: We test the performance of two ESG score-driven quantitative signals on a large, multi-national crosssection of European stock returns. In particular, we ask whether in the cross-section, the cost of equity capital is more strongly affected by the (upward) “slope” (identified as momentum over […]
Speaker: Prof. Lorenzo Mercuri, Dept. of Economics, Management & Quantitative Finance Methods, University of Milan Abstract: The paper investigates the effect of the label green in bond markets from the lens of the trading activity. The idea is that jumps in the dynamics of returns have a specific memory nature that can be well represented […]
Speaker: Dr. Konstantin Ignatov, WHU - Otto Beisheim School of Management Abstract Since the ESG topic consistently gains on importance in the investment universe, companies provide investors with information regarding recent and future ESG activities through different reporting channels. The most recent research finds relevance of ESG-related corporate activities for formation of investors' opinion regarding […]
Speaker: Prof. Abootaleb Shirvani, Dept. of Mathematical Sciences, Kean University Abstract: Understanding the volatility of speculative assets is critical for investment decisions. Given that Bitcoin is considered, at least by some, a potential alternative to fiat money, its volatility characteristics are of particular concern. It is, therefore, essential to comprehend and appropriately model the process […]
Speaker: Prof. Massimiliano Kaucic, Department of Economics, Business, Mathematics & Statistical Sciences, University of Trieste Abstract: In the last five years, extreme events such as the COVID-19 pandemic and the Ukrainian crisis have highlighted the importance of corporate social responsibility and sustainable principles. Consequently, the investment process is changing toward more ethical choices. In this […]
Speaker Dr. Gudmund Pammer, Dept. of Mathematics, ETH Zürich Abstract: The Bass local volatility model introduced by Backhoff-Veraguas–Beiglböck–Huesmann–Källblad is a Markov model perfectly calibrated to vanilla options at finitely many maturities, that approximates the Dupire local volatility model. Conze and Henry-Labordère show that its calibration can be achieved by solving a fixed-point nonlinear integral equation. […]
Speaker: Prof. Olivier Guéant, Department of Applied Mathematics, Université Paris 1 Panthéon-Sorbonne Abstract: Modern portfolio theory has provided for decades the main framework for optimizing portfolios. Because of its sensitivity to small changes in input parameters, especially expected returns, the mean-variance framework proposed by Markowitz (1952) has however been challenged by new construction methods that […]
Speaker: Dr. Grzegorz Krzyżanowski, Hugo Steinhaus Center, Faculty of Pure and Applied Mathematics, Wroclaw University of Science and Technology Abstract: We will investigate the relation between Bachelier and Black-Scholes models driven by the infinitely divisible inverse subordinators. Such models, in contrast to their classical equivalents, can be used in markets where periods of stagnation are […]
Speaker: Prof. Tauhidul Islam Tanin, EGADE Business School, Technologico de Monterrey Abstract: We examine the impact of ESG practices on financial performance among Nifty 50 companies in India from 2015 to 2022. Utilizing fixed-effects panel quantile regression, we observe that the relationship between ESG practices and financial profitability varies across the ROE distribution. While the […]
