Abstract

El documento utiliza la expansión de Edgeworth en el modelo de Black-Scholes para estimar la volatilidad implícita y el impacto en el precio de la opción de los momentos estocásticos de orden superior, sobre contratos de opciones del Grupo Financiero Galicia (GGAL), negociados en la Bolsa de Comercio de Buenos Aires (Argentina). Primero se analiza la distribución de probabilidad de rendimientos de subyacente; luego, el modelo se somete a iteración para obtener los valores implícitos de la volatilidad, asimetría y curtosis. Como principal conclusión se encuentran la forma aplanada de la curva de volatilidad implícita del modelo y el significativo peso de la asimetría y curtosis en el precio de las opciones «muy fuera/dentro del dinero».
