Short Call Butterfly Example
Assumption: XYZ is trading at $40.50 a share on Mar 20X1. The verdict of a legal law suit against the company is expected to be made soon. You are expecting share price of XYZ to soar up or plummet down once the verdict is out. You would like to profit from the volatility of this stock without any capital outlay. In this case, you may consider to sell one Jun 20X1 $35 strike call at $7.50, buy two Jun 20X1 $40 strike call at $4.50 and sell one Jun 20X1 $45 strike call at $2.40 to profit from the volatile outlook of the stock. Note: commissions are NOT taken into account in the calculation.
Analysis of Short Call Butterfly Example
= Limited to the different in adjacent strikes less net premium collected
= ($5 - $0.90) * 100 = $410
= Net Premium Collected = Premium Collected less Premium Paid
= ($7.50 - $4.50 - $4.50 + $2.40) * 100 = $90
= Higher Strike Price Less Net Premium Collected
= $45 - $0.90 = $44.10
= Lower Strike Price Add Net Premium Collected
= $35 + $0.90 = $35.90
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.
