La estrategia que ofrece FMZ Quant es la estrategia de cobertura dinámica delta de Deribit Options, o en sus siglas DDH (Dynamic Delta Hedging).
· Modelo de fijación de precios de las opciones, modelo B-S, los precios de las opciones se determinan sobre la base de [precio objeto], [precio de uso de la potencia], [tiempo restante hasta la expiración], [implicada volatilidad] y [tasa libre de riesgo].
· Exposición a las opciones:
-Delta
· Explicación del principio DDH La dirección de negociación neutra en cuanto al riesgo se consigue mediante el emparejamiento del delta de las opciones y futuros. Después de tomar una posición en un contrato de opción y equilibrar el Delta con la cobertura de futuros, el Delta general se desequilibrará nuevamente a medida que el precio del objeto se mueva.
· Por ejemplo: Cuando compramos una opción de compra, mantenemos una posición en la dirección larga en este momento. En este momento, es necesario hacer un cortocircuito en los futuros para cubrir el Delta de opciones, alcanzando el Delta neutral general (0 o cercano a 0). Ignoremos el tiempo restante hasta la expiración del contrato de opción, la volatilidad y otros factores. Escenario 1: Cuando el precio de la materia objeto aumenta, el Delta de las opciones aumenta, y el Delta general se mueve a un número positivo, y los futuros necesitan cubrirse de nuevo. (Antes del reequilibrio, el delta de las opciones es grande, mientras que el de los futuros es relativamente pequeño.
Escenario 2: A medida que el precio del objeto cae, la parte de la opción del Delta disminuye y el Delta general se mueve a un número negativo, cerrando una parte de la posición de futuros cortos y volviendo a equilibrar el Delta general. (Antes del reequilibrio, en este momento, el delta de las opciones es pequeño, mientras que el de los futuros es relativamente grande. La pérdida marginal de las opciones de compra es menor que la ganancia marginal de las posiciones cortas del contrato, y toda la cartera seguirá produciendo ganancias.)
Por lo tanto, en un estado ideal, el aumento y la disminución del objeto traerá beneficios mientras el mercado fluctúe.
Sin embargo, también hay factores a tener en cuenta: el valor del tiempo, los costos de transacción y otros factores.
Por lo tanto, se cita la explicación de un hombre importante en Zhihu:
The focus of Gamma Scalping is not on delta, dynamic delta hedging is just a way to avoid underlying price risk in the process.
Gamma Scaling focuses on alpha, which is not the alpha of stock selection. Here, alpha=gamma/theta, that is, how much gamma is exchanged for the time loss of unit Theta.
This is the point of concern. It is possible to construct a portfolio that floats both up and down, but it must be accompanied by time loss, and then the problem lies in the cost effectiveness.
