A Short Call Butterfly consists of three equally spaced strike prices. It gets the name from the shape of its profit and loss graph at expiration. The 2 outside strike are commonly referred to as the wing, whereas the 2 middle strikes are commonly referred to as the body. It is a four –legged spread option strategy consisting of all calls and is the opposite of Long Call Butterfly, which is a sideway strategy

Before you executed a Short Call Butterfly strategy, you must first determine at which price the underlying stock will most probably NOT be trading at the expiration date. This will be strike price (middle) where you will purchase the two options. Next sell a lower strike option and a higher strike option with equal distance from the middle strike purchased.

Typically when you short a butterfly, you will receive credit from the trade. This will be your maximum profit at expiration when the underlying stock close below the lower strike or above the higher strike. The maximum loss will occur when the underlying stock close at the middle strike price at expiration day.

Time decay is generally harmful to this strategy as you need a lot of movement in the underlying stock for the trade to be profitable.

Once it is in a profitable position, time decay will become helpful.

Therefore it is preferably to use this option trading strategy with at least 3 months left to expiration so as to give yourself more time to be right


You may also execute the Short Butterfly strategy using all puts options. When all puts options are used, it is referred to as the Short Put Butterfly strategy. The characteristic of Short Put Butterfly is the same as a Short Call Butterfly. As to whether a butterfly strategy should be executed using all calls or all puts options depend on the relative price of the option. The premium of both puts and calls option should be taken into consideration to achieve the optimum trade. You should pick the strike price and time frame of the Short Call Butterfly according to your risk/reward tolerance and forecast outlook of the underlying stock. Selecting the option trading strategies with appropriate risk-reward parameters is important to your long term success in trading options.
