TY - JOUR ID - 1676599 AU - Araneda, Axel Alejandro PY - 2020 TI - The fractional and mixed-fractional CEV model JF - Journal of Computational and Applied Mathematics VL - 363 SP - 106-123 EP - 106-123 PB - Elsevier Science SN - 03770427 KW - fBM KW - mfBm KW - CEV KW - Fractional Fokker-Planck KW - Fractional Ito's calculus KW - Feller's process N2 - The continuous observation of the financial markets has identified some 'stylized facts' which challenge the conventional assumptions, promoting the born of new approaches. On the one hand, the long-range dependence has been faced replacing the traditional Gauss-Wiener process (Brownian motion), characterized by stationary independent increments, by a fractional version. On the other hand, the CEV model addresses the Leverage effect and smile-skew phenomena, efficiently. In this paper, these two insights are merging and both the fractional and mixed-fractional extensions for the CEV model, are developed. Using the fractional versions of both the Ito's calculus and the Fokker-Planck equation, the transition probability density function of the asset price is obtained as the solution of a non-stationary Feller process with time-varying coefficients, getting an analytical valuation formula for a European Call option. Besides, the Greeks are computed and compared with the standard case. (C) 2019 Elsevier B.V. All rights reserved. ER -
