A Jump Telegraph Model for Option Pricing

  • Nikita Ratanov

    ()

In this paper we introduce a financial market model based on continuous time random motions with alternating constant velocities and with jumps occurring when the velocity switches. If jump directions are in the certain correspondence with the velocity directions of the underlying random motion with respect to the interest rate, the model is free of arbitrage. The replicating strategies for options are constructed in details. Closed form formulas for the option prices are obtained. En este trabajo se presenta un modelo de mercado financiero basado en movimientos aleatorios de tiempo continuo con velocidades constantes alternantes que ocurren cuando cambia la velocidad. Si las direcciones de los saltos se encuentran en determinada correspondencia con las direcciones de velocidad de los movimientos aleatorios subyacentes con respecto a la tasa de interés, entonces el modelo está libre de arbitraje. Las réplicas de estrategias para opciones se construyen en detalle. Se obtienen fórmulas de forma cerrada para los precios de las opciones.
