stochastic volatility model and all of its extensions, involve multivalued functions such as the …

[PDF][PDF] Not-so-complex logarithms in the Heston model

C Kahl, P Jäckel - Wilmott magazine, 2005 - math.uni-wuppertal.de
In Heston's stochastic volatility framework [Hes93], semi-analytical formulæ for plain vanilla
option prices can be derived. Unfortunately, these formulæ require the evaluation of …

A fast mean-reverting correction to Heston's stochastic volatility model

JP Fouque, MJ Lorig - SIAM Journal on Financial Mathematics, 2011 - SIAM
We propose a multiscale stochastic volatility model in which a fast mean-reverting factor of
volatility is built on top of the Heston stochastic volatility model. A singular perturbative …

Gamma expansion of the Heston stochastic volatility model

P Glasserman, KK Kim - Finance and Stochastics, 2011 - Springer
We derive an explicit representation of the transitions of the Heston stochastic volatility
model and use it for fast and accurate simulation of the model. Of particular interest is the …

The Alpha‐Heston stochastic volatility model

Y Jiao, C Ma, S Scotti, C Zhou - Mathematical finance, 2021 - Wiley Online Library
We introduce an affine extension of the Heston model, called the‐Heston model, where the
instantaneous variance process contains a jump part driven by‐stable processes with. In this …

Efficient, almost exact simulation of the Heston stochastic volatility model

A Van Haastrecht, A Pelsser - International Journal of Theoretical …, 2010 - World Scientific
We deal with discretization schemes for the simulation of the Heston stochastic volatility
model. These simulation methods yield a popular and flexible pricing alternative for pricing …

[图书][B] Modelling and simulation of stochastic volatility in finance

C Kahl - 2008 - books.google.com
The famous Black-Scholes model was the starting point of a new financial industry and has
been a very important pillar of all options trading since. One of its core assumptions is that …

Time dependent Heston model

E Benhamou, E Gobet, M Miri - SIAM Journal on Financial Mathematics, 2010 - SIAM
The use of the Heston model is still challenging because it has a closed formula only when
the parameters are constant [S. Heston, Rev. Financ. Stud., 6 (1993), pp. 327–343] or …

Pricing options under stochastic volatility: a power series approach

F Antonelli, S Scarlatti - Finance and Stochastics, 2009 - Springer
In this paper we present a new approach for solving the pricing equations (PDEs) of
European call options for very general stochastic volatility models, including the Stein and …
