Speaker: Prof. Andrey Itkin, Department of Risk and Financial Engineering, Tandon School of Engineering, NYU Abstract: In this paper we propose a semi-analytic approach to pricing American options for some time-dependent jump-diffusions models. The idea of the method is to further generalize our approach developed for pricing barrier, , and American, , options in various […]
Speaker: Prof. Abderrahim Taamouti, Management School, University of Liverpool Abstract: The Sharpe-ratio-maximizing portfolio becomes questionable under non-Gaussian returns, and it rules out, by construction, systemic risk, which can negatively affect its out-of-sample performance. In the present work, we develop a new performance ratio that simultaneously addresses these two problems when building optimal portfolios. To robustify […]
Speaker: Prof. Peter Bank, Department of Mathematics, Technical University of Berlin Abstract: We consider the problem of hedging a European contingent claim in a Bachelier model with temporary price impact as proposed by Almgren and Chriss (J Risk 3:5–39, 2001). Following the approach of Rogers and Singh (Math Financ 20:597–615, 2010) and Naujokat and Westray […]
Speaker: Prof. Md. Rayfayet Alam, Dept. of Finance and Economics, University of Tennessee at Chattanooga Abstract: This study evaluates the potential of gold-backed cryptocurrencies, such as Tether Gold and PAX Gold, as a hedge and safe haven against global, regional, and categorical financial stresses. Hedge and safe haven properties of gold-backed cryptocurrencies are also compared […]
Speaker: Dr. Evangelos Melas, Department of Mathematics, University of Thessaly Abstract: Under the recent negative interest rate situation, the Bachelier model has been attracting attention and adopted for evaluating the price of interest rate options. In this paper we find the Lie point symmetries of the Bachelier partial differential equation (PDE) and use them in […]
Speaker: Prof. Aaron YS Kim, College of Business, Stony Brook University Abstract: In this study, we discuss a machine learning technique to price exotic options with two underlying assets based on a non-Gaussian Levy process model. We introduce a new multivariate Levy process model named the generalized normal tempered stable (gNTS) process, which is defined […]

Rayfayet Alam, Dept. of Finance and Economics, University of Tennessee at Chattanooga Abstract: This study evaluates the potential of gold-backed cryptocurrencies, such as Tether Gold and PAX Gold, as a hedge and safe haven against global, regional, and categorical financial stresses. Hedge and safe haven properties of gold-backed cryptocurrencies are also compared […]
Speaker: Prof. Ralf Korn, Dept. of Mathematics, RPTU Kaiserslautern-Landau Abstract: Since August 2022 customers have to be asked if they are interested in sustainable investment when entering a pension contract. Hence, the provider has to be prepared to offer suitable investment opportunities. Further, the provider has to manage the new risks and chances of those […]
Speaker: Prof. Agata Kliber, Dept of Applied Mathematics, Poznan University of Economics & Business co-Authors: Prof. Krzysztof Echaust, Dept. of Operations Research & Mathematical Economics, Poznan University of Economics & Business Prof. Małgorzata Just, Dept. of Finance & Accounting, Poznan University of Life Sciences Abstract: The article aims to determine whether any hedging strategy against […]
Speaker: Prof. Seda Erdogan, Dept. International Trade & Finance, Kadir Has University Abstract: This paper investigates the relationship between firms' engagement in environmental, social, and governance (ESG) activities and corporate investment efficiency, using 1,094 firms from 21 countries in Europe, covering the years 2002–2019. We conduct our estimations using fixed effects panel data techniques and […]
Speaker: Prof. Steven P. Clark, Dept. of Finance, UNC Charlotte Abstract: We introduce a novel option pricing model that features stochastic interest rates along with an underlying price process driven by stochastic string shocks combined with pure jump Lévy processes. Substituting the Brownian motion in the Black–Scholes model with a stochastic string leads to a […]
Title: Time changes, Fourier transforms and the joint calibration to the S&P500/VIX smiles Speaker: Prof. Laura Ballotta, Bayes Business School, City University of London Abstract: We develop a model based on time changed Lévy processes and study its ability of reproducing the joint S&P500/VIX implied volatility smiles and the VIX futures prices - a problem […]
