Option pricing and portfolio optimization under a multi-asset jump-diffusion model with systemic risk
Makarov, Roman - In: Risks : open access journal 11 (2023) 12, pp. 1-24
We explore a multi-asset jump-diffusion pricing model, combining a systemic risk asset with several conditionally independent ordinary assets. Our approach allows for analyzing and modeling a portfolio that integrates high-activity security, such as an exchange trading fund (ETF) tracking a...

Madan, Dilip B.; Schoutens, Wim - In: Journal of risk and financial management : JRFM 12 (2019) 2/69, pp. 1-21
It is argued that the growth in the breadth of option strikes traded after the financial crisis of 2008 poses difficulties for the use of Fourier inversion methodologies in volatility surface calibration. Continuous time Markov chain approximations are proposed as an alternative. They are shown...

No-arbitrage principle in conic finance
Vazifedan, Mehdi; Zhu, Qiji Jim - In: Risks : open access journal 8 (2020) 2/66, pp. 1-34

A general framework for portfolio theory, part III, multi-period markets and modular approach
Maier-Paape, Stanislaus; Platen, Andreas; Zhu, Qiji Jim - In: Risks : open access journal 7 (2019) 2/60, pp. 1-31
This is Part III of a series of papers which focus on a general framework for portfolio theory. Here, we extend a general framework for portfolio theory in a one-period financial market as introduced in Part I [Maier-Paape and Zhu, Risks 2018, 6(2), 53] to multi-period markets. This extension is...
