Precios de opciones bidireccionales máximas-mínimas en el modelo ECV trinomial Códigos JEL: C14 F17 Palabras clave: Modelo ECV trinomial Algoritmo recursivo Opciones bidireccionales máximas-mínimas r e s u m e n Las opciones bidireccionales máximas-mínimas son un tipo de opciones exóticas dependientes de la trayectoria. En el modelo de elasticidad constante de la varianza (ECV), se estructuró un árbol trinomial combinado para aproximar la volatilidad no constante, que es una función del activo subyacente. En base a esto se desarrolló un algoritmo sencillo y eficaz para calcular la probabilidad de neutralidad al riesgo de cada nodo del activo subyacente llegando a un precio máximo o mínimo y el número total de máximos (mínimos) del árbol trinomial. De esta manera, los problemas computacionales pueden resolverse eficazmente a raíz de las complejidades inherentes a los distintos tipos de opciones bidireccionales máximas-mínimas cuando el activo subyacente evoluciona como el modelo ECV trinomial. Los resultados numéricos demuestran la validez y convergencia del enfoque anteriormente mencionado para los parámetros de valores establecidos en el modelo ECV trinomial. © 2016 Publicado por Elsevier España, S.L.U. en nombre de Universidad ESAN.

Valuing Time-Dependent CEV Barrier Options
We have derived the analytical kernels of the pricing formulae of the CEV knockout options with time-dependent parameters for a parametric class of moving barriers. By a series of similarity transformations and changing variables, we are able to reduce the pricing equation to one which is reducible to the Bessel equation with constant parameters. These results enable us to develop a simple and ...
متن کاملPricing Options and Equity-Indexed Annuities in a Regime-switching Model by Trinomial Tree Method
In this paper we summarize the main idea and results of Yuen and Yang (2009, 2010a, 2010b) and provide some results on pricing of Parisian options under the Markov regime-switching model (MRSM). The MRSM allows the parameters of the market model depending on a Markovian process, and the model can reflect the information of the market environment which cannot be modeled solely by linear Gaussian...

متن کاملThe Bino-trinomial Tree: a Simple Model for Efficient and Accurate Option Pricing
Most derivatives do not have simple valuation formulas and must be priced by numerical methods. However, the distribution error and the nonlinearity error introduced by many numerical methods make the pricing results converge slowly or even oscillate significantly. This paper introduces a novel tree model, the bino-trinomial tree (BTT) model, for pricing a wide range of derivatives. The BTT red...
متن کاملVery Fast Algorithms for Barrier Option Pricing and the Ballot Problem
Combinatorial methods prove extremely useful towards designing blazingly fast yet simple algorithms for pricing European-style barrier options. Closed-form formulae to standard European-style barrier options can then be easily derived. Combinatorial formulae under the trinomial model are also presented. The common practice in the literature compares algorithms based on their respective numbers ...
