Explanation
A short call butterfly option strategy is opposite of long call butterfly spread. It is a three-part strategy that involves selling and buying call option. Implementation of this option strategy involves selling one higher out-of-the-money (OTM) strike call, buying two middle at-the-money (ATM) strike calls, and selling one lower in-the-money (ITM) strike call. All call options should have the same expiry date, and the distance between the higher and lower strikes must be equal from the middle strike. The short call butterfly option strategy is implemented for a net credit and both profit and loss are limited.
Reward
Maximum profit is realized when the underlying security price at expiration closes above the higher strike call or below the lower strike call.
If prices close above the higher strike call, all the strike will become in the money and the trader implementing this option strategy will make loss on 1 long call but will profit from 2nd long calls.
If the prices of the underlying fall below the lower strike call, all the strikes will become out of the money and trader stand to gain from the premium received.
Risk
Maximum loss will be realized if the underlying price closes near to the long call option. In such scenario, the long call will expire worthless and trader stands to loss from the short lower call.
