Long Call Spread : Vega
Issued on August 17 2010 par Strategies-options.com

Implied volatility sensitivity for the call spread.
Call spreads are sensible to implied volatility variations. It leads to study the vega.



I - The vega of a call spread

The call spread being a strategy on the same term for both calls, we can study simply the sensibility of the strategy to a variation of the implied volatility by the vega.



II - The graph of vega for a call spread

By leaving of the principle that an increase / decline of 1 point of volatility echoes in a identical way on both volatilities of the options, we can represent diagrammatically the sensibility of the call spread to a variation of the implied volatility so :

3D Vega long call spread 100/120


We shall have the opportunity soon to study this same sensibility for calls having different implied volatilities and in the case of not identical variations of the implied volatilities.
