Call butterfly an option trading strategy is also known as a long butterfly strategy. It is a multi -legged and neutral strategy. In this strategy, the risk is predefined, having limited profit potential. This strategy can be very beneficial when the volatility declines, time decays, and if there is a low movement in the underlying asset price.
In the call butterflies, there are four call options, all having the same expiry date. Of
these four, traders sell two short call options, buy one long call option above the short
strike price and buy the fourth long call option below the short strike price. A call
butterfly strategy is made up of selling the bull call debit spread and bear call credit
spread at the same strike price. The long call options contract is at an equal distance
to the short call options.
Traders can enter a call butterfly by paying a very small debit. Whatever amount is
paid by the traders initially is the highest risk. The highest profit potential is the gap
between the long strikes and short strikes minus the debit amount paid.
This strategy takes advantage of a decline in volatility, time decay factor or low or
no movement in the underlying asset price.
Call butterfly strategy from the market’s perspective:
Call butterflies strategy is a market-neutral strategy with no biases based on direction.
The strategy depends majorly on the low price movement of the underlying stock to
be profitable. In order to get maximum profit potential, the stock must close within the
strike price at the time of expiry. The highest amount a trader can lose is initially paid
while entering the strategy. Suppose, if at the time of expiry, the stock closes above the
higher strike price or below the lower strike price of long call options, then there will be
a maximum loss to the traders. Traders may enter the call butterfly strategy when he
expects that the stock prices will stay in between the ranges till they expire.
How can I set up a call butterfly strategy?
Call butterflies are short straddles with the long call option protection either above or
below the short strikes to limit the risk. The main objective of this strategy is that it must expire near the stock price at the time of expiry. This leads to the long call option, which is above the short strikes to expire out-of-the-money and the other long call option, which is below the short strikes to expire in-the-money.
Traders can get the highest profit by selling the in-the-money long call options and
buying the short call options again at a very small or no cost. The difference amount
the trader gets by selling in-the-money long call options, buying the short options
and deducting the initial debit paid will be the highest profit. On the other hand, if the
stock prices close either above or below the long call strike prices at the time of expiry,
it will result in a loss.
Suppose the stock prices close below the lower long call; then the options contract
will be out-of-the-money and expire worthlessly; the debit paid initially will turn into
a loss. If the stock price closes above the price of a higher long call, all four options
will expire in-the-money. If, in this case, the trader closes the entire position after its
expiry, then all four options would have to be executed and cancelled out, and the
initial debit paid will be lost.
Understanding the diagram of the call butterfly:
The diagram of the long call butterfly shows the highest risk and reward to the traders.
The highest loss to the traders is defined by combining the cost of all four options of
the underlying stock and can be realized if the stock closes above or below the long
options at the time of expiry. The profit in this strategy is limited to the width of the
spread between the lower long call options and two short call options contracts minus
the amount paid initially at the entry.
For example: let us assume that a call butterfly is cantered at Rs. 100. It has two
short call options at a strike price of Rs. 110 and two long call options at a strike price
of Rs. 90. Assuming the cost to enter the trade being Rs. 5, these Rs. 5 will be the
maximum loss to the trader. If the stock price closes at Rs.100 during the expiry, then
the two short-call options will expire worthlessly. The long call options of strike price
will be in-the-money by Rs. 10. If we deduct the initial debit paid to enter the trade -
Rs. 5, the strategy can earn the highest profit of Rs. 500.
If the stock price moves higher than Rs. 100 during expiry, but it is within the protective
wing of the long call option, then two short options will be in-the-money and will still
have some value left for profit. Traders need to repurchase in-the-money short options.
Whatever amount is involved in repurchasing the short options, selling the lower strike
long options contract with the remaining intrinsic value, and the initial debit paid to
enter the trade will decide the traders' net profit or a net loss.
If the stock price closes below Rs. 100 during the expiry, both the short and long call
options will expire worthlessly, and traders need to close the lower long calls. The credit
received by selling the call option minus the debit paid to enter will be the amount of
the trader's profit or loss.
The strategy can be said close at the break-even point if the underlying stock price is
either above or below the long call option by the amount equal to the premium paid.
In the example considered above - the downside break-even point will be Rs. 95
(lower strike Rs. 95 - Rs.5 net debit), and the upside break-even point will be Rs. 105
(higher strike price Rs. 110 - Rs.5 net debit).
How can I enter a call butterfly options strategy?
A trader can enter the call butterfly with two sell-to-open (STO) call options at the same strike price and buy-to-open (BTO) two long call options, one above and the second below the short call options. All the call butterfly's four legs/ options contracts should expire on the same date. Traders do not need to sell a short call at at-the-money; instead, they are sold at the strike price, as the traders believe the stock will expire at the same price. The closer the stock price towards the short call options at the time of expiry, the more profit can be generated.
Focusing the call butterfly strategy below the current strike price will create a bearish
bias, as the stock price must decline to make the position profitable. Conversely,
focusing the call butterfly above the current strike price will create a bullish bias; in
this case, the stock price needs to rise to make the position profitable.
How can I exit the call butterfly strategy?
The call butterfly strategy can achieve maximum profit if the stock closes at exactly
the same price as the short strikes during the expiry. In this case, the short call option
will expire worthlessly, and the long call options that are in-the-money can be sold out.
The total width of the spread minus the initial debit paid results in the net profit to the
Suppose the stock prices close above the short call during expiry but still lie in the
protective wing of the long call; then, both short options will be in-the-money and
have some value left. The trader should repurchase an in-the-money short option.
The difference a trader gets from selling the lower call options, buying back the short
options, and the initial debit paid will result in either profit or loss of the trade.
If the stock price closes below the short options during expiry, then short and higher
long calls will expire worthlessly, and traders need to close the lower long options.
The credit amount received by selling the call options and deducting the initial debit
paid will give you the profit or loss on this trade.
Impact of the time decay on call butterfly strategy:
The time decay or theta factor works in favour of the call butterfly strategy. With each
passing day, the contract value decreases, which helps lower the value of two short
options. Generally, the stock faces limited movement, and theta will lose its value by
the time of expiry. Suppose the trader has sold or exited the long call before they expire. This decline in the theta will allow the trader to enter the trade again by purchasing the options at the low price then they were sold. At the same time, in-the-money long options will still have some intrinsic value left.
Impact of implied volatility on the call butterfly strategy:
Call butterfly strategy gets the benefit of the volatility decreases in the underlying
stock. Lower implied volatility will reduce the prices of options premiums. Generally,
at the beginning of the call butterfly, the volatility is high and reduces as the expiry
time approaches. Low implied volatility will reduce the value of the two short-call
options. Although it is challenging to predict volatility, knowing its impact on your
position might help you.
How can I adjust the call butterfly strategy?
Traders may adjust the call butterflies before the contract expires to extend the time
or to rebalance the short strikes in case they have shifted from the profit zone. Call
butterflies are the net debit strategies, so if traders try to adjust it, it will raise the
additional cost to the position, the risk will increase, the potential to profit will also
reduce, and the break-even points will be narrowed. As the call butterfly is made up
of two short contracts, the risk will be very high if they get executed before the expiry.
Traders must keep in mind some external factors, such as dividends while adjusting
or closing the butterfly position. If a trader wants to buy more time to let the situation
turn in their favour and make a profit, then the entire position can be closed and
reopened at some future date, either with the same strike price or new strike prices.
How can I roll the call butterfly strategy?
Call butterflies are needed to stay at or near a specific price at the time of expiry. If
the current position does not seem profitable, and traders wish to expand the trade
length, then the call butterflies can be closed and reopened at some future expiry date.
If you buy more time, there are chances that the options prices may rise so rolling will
add extra money to the short call options along with the risk. Suppose the stock price has moved away from the short call options, then closing the entire position and
entering again into a call butterfly with the price closer to the current stock price would be a wise choice. But, while doing so, if the debit paid exceeds the width spread, the position will no longer stay profitable, and the rolling will make no sense.
How to hedge a call butterfly?
It is difficult to hedge a long call position of the butterfly spread, as the strategy
depends on hitting the specific price to be profitable. As the strategy already has a
very limited risk structure, hedging might be unnecessary. Traders buy the long call
options to provide protection against the large moves of the underlying asset. Hence,
the risk factor in this strategy is well defined at the entrance of the trade.
Call broken wing butterfly:
You will find only slight changes in the structure of the broken wing butterfly and long
call options. Call broken wing is made by buying one in-the-money long call, selling
two out-of-the-money short call options, and buying one out-of-the-money long
call option above the price of the short call. Call broken-wing butterflies are centered
at the bull call spread, and the bear call spread has the same strike price. However,
one long call option, which is out-of-the-money and above the short strike price, is
not at an equal distance from the out-of-the-money long call below the short call's
When buying long call options above the short calls options, the trader skipped one
strike price, which creates the "broken wing." Thus, this strategy gets a net credit while
entering the trade. Call broken wings butterflies are a little bullish and get positively
impacted by the time decay and volatility factor, just like the call butterfly.
If the stock price closes at the short strike price at the time of expiry, it would be the
best and ideal scenario. If the position is opened for credit, then any price movement
or decline in the price will not result in a profit.
The highest profit potential to a trader is the total credit received plus the width of the
bull call spread, and it can be realized only when the stock closes at the short call
options. The highest risk to the trader is the width spread below the short strike prices
minus the credit received. The break-even point is the one that is skipped plus the
For example: If a stock has a current price of Rs. 98 and the trader expects that
there might be some change but a significant one. He may enter a call broken-wing
butterfly by buying a call of strike price Rs. 95, selling the two calls at Rs. 100 and buying a long call at Rs. 110. If, in this trade, the trader collects a credit of Rs. 1, the maximum profit can be Rs. 600 if the stock closes at Rs. 100 during expiry because the long calls will still have Rs. 5 intrinsic value plus the credit received initially. The short calls and out-of-the-money long calls will expire worthlessly. The highest risk is Rs. -400 if the stock price closes at or above Rs. 110. Suppose the stock closed at Rs. 110, then the
long call of Rs. 95 will still have the intrinsic value of Rs. 15, but the other two short
options will be Rs. 10 in-the-money. (Rs.15-Rs.20+Rs.1 =Rs. 4) The break-even point
here is Rs. 106 as the long call of Rs. 95 will have Rs. 11 intrinsic value, and each short
call would have Rs. 6 in-the-money and Rs. 1 credit received. Now, if the stock prices
fall below Rs. 95, options will expire worthlessly, and only Rs. 1 received as credit will
be the profit.
