Definition: A neutral strategy with low risk is the butterfly spread option, often known as the butterfly option. The option strategy uses a variety of bull spreads and bears spread combined. A holder can establish an ideal range of pricing and profit by combining four options contracts with the same expiration date at three strike price points. The intermediate strike price is equal to the difference between the high and low strike prices. A trader buys two option contracts, one at a higher strike price and one at a lower strike price, and sells the remaining two option contracts at the midpoint of the strike price range.
long butterfly spread
By purchasing one call at a lower strike price, selling two calls at a higher strike price, and then purchasing one call at an even higher strike price, a long butterfly spread with calls is established. The strike prices are equally spaced apart, and all calls have the same expiration date. One 95 Call is bought in the case above, two 100 Calls are sold, and one 105 Call is bought. The possible profit and maximum risk are both constrained by the fact that this technique is designed for a net debit. If the stock price on the expiration date is equal to the center strike price of the short calls, the maximum profit is attained. The maximum risk, which is equal to the net cost of the strategy, including fees, is realized if the stock price is above the highest strike price or below the lowest strike price at expiry.
Given the limited possibilities for financial gain and substantial "costs," this is an advanced technique. There are additional commissions in addition to the three bid-ask spreads when taking the position and again when closing it because there are three strike prices. It is crucial to open and finish the position at "excellent pricing". Ensure the risk/reward ratio, taking commissions into account, is favorable or acceptable.
maximum revenue
If the stock price at expiry is identical to the short call's strike price (center strike), the maximum profit potential may be realized. The profit is determined by subtracting the net cost of the position, which includes fees, from the difference between the lowest and middle strike prices.
The net cost of the approach in the example above, without commissions, is 1.25, and the difference between the lowest and middle strike prices is 5.00. Therefore, the maximum profit is 3.75 fewer commissions.
Maximum danger
There are two scenarios in which a loss of this amount is realized, and the maximum risk is equal to the net cost of the approach, including fees. All calls expire worthlessly, and the entire cost of the strategy, including commissions, is lost if the stock price is lower than the lowest strike price at expiration. Additionally, if the stock price is greater than the highest strike price at expiry, all calls are in the money and the butterfly spread position has a net value of zero. The full cost of the post, including commissions, is thus forfeited.
At expiration, the stock price is at breakeven.
There are two breakeven points. The stock price equal to the lowest strike price plus the cost of the position, including commissions, equals the lower breakeven point. The stock price less the position's cost is the upper breakeven point, which is equal to the highest strike price.
Suitable market forecast
The greatest profit from a long butterfly spread with calls is realized if the stock price on the expiration date equals the center strike price. Therefore, depending on how the stock price relates to the center strike price when the position is placed, the projection may be "neutral" or "modestly optimistic."
The projection must be for unchanged or neutral price action if the stock price is at or close to the center strike price when the trade is placed.
The prediction must predict that the stock price will increase to the center strike price at expiration if it is below the center strike price when the position is established (modestly bullish).
While it is conceivable that a long butterfly spread with calls may profit from bearish stock price action if the stock price were above the center strike price, it is more likely that a different approach would be a more profitable alternative for a bearish projection.
When the forecast calls for stock price movement close to the spread's center strike price, a long butterfly spread with calls is the best course of action because long butterfly spreads benefit from time decay. The potential risk of a long butterfly spread is constrained, in contrast to that of a short straddle or short strangle. The disadvantage is that compared to a comparable short straddle or short strangle, a long butterfly spread has a substantially smaller dollar profit potential. Additionally, a butterfly spread has greater commissions than a straddle or strangle.
Long butterfly spreads are responsive to volatility swings (see Impact of Change in Volatility). When volatility increases, a butterfly spread's net price decreases, and when volatility decreases, it increases.
As a result, some traders purchase butterfly spreads when they anticipate a decrease in volatility.
Some traders would purchase a butterfly spread right before an earnings release because the volatility in option pricing typically declines substantially after them. The risk is restricted to the position's cost, which includes commissions, and the potential reward is "substantial" in percentage terms. The stock price must remain between the lower and upper butterfly strike prices for this method of purchasing butterfly spreads to be successful. A loss will be realized if the stock price fluctuates excessively in either direction.
Long butterfly spreads with calls do not show much of a profit if volatility is continuous until the stock price is extremely near to the center strike price and the spread is very close to expiration. As long as the stock price stays inside the profit zone, short straddles and short strangles, in contrast, start to show at least some profit early in the expiration cycle.
Additionally, while a long butterfly spread has a "high percentage profit on the capital at risk" as its prospective profit, its typical dollar cost is "modest." As a result, if the objective is to make a profit in dollars equal to the hoped-for dollar benefit from a short straddle or strangle, it is frequently required to trade a lot of butterfly spreads. Don't forget that a long butterfly spread still carries a risk equal to 100% of the position's cost. As a result, a trader needs to be prepared to exit the position before suffering a substantial percentage loss if the stock price starts moving in either direction: below the lowest or above the highest strike price.
Trading long butterfly spreads require patience and trading discipline. This method relies on time decay, which requires patience, and the stock price action, which fluctuates about the center strike price as expiration draws near, can be uncomfortable. Trading restraint is necessary since the price of a butterfly spread can fluctuate significantly as expiration draws near due to "small" changes in stock price. Therefore, traders must exercise discipline in taking partial profits when possible and taking "minor" losses before they grow larger.
Effect of a change in stock price
According to fluctuations in the stock price, "Delta" predicts how much a position will change in price. Deltas are favorable for long calls and negative for short calls.
The net delta of a long butterfly spread stays relatively constant until one or two days before expiration, independent of the remaining time before expiration or the stock price. The net delta is positive if the stock price is below the lowest strike price in a long butterfly spread with calls. The net delta is negative if the stock price exceeds the highest strike price. Overall, as long as the stock price is between the highest and lowest strikes, a long butterfly spread with calls makes money from time decay rather than stock price changes.
Effect of volatility changes
Volatility is a percentage-based indicator of how much a stock price swings and influences option prices. If other variables like stock price and time till expiration are constant, option prices tend to increase as volatility increases. As a result, when volatility increases, the price of long options increases, and they profit, while the price of short options increases, and they lose money.
The opposite occurs when volatility declines; long options are profitable, while short options are profitable. The term "Vega" describes how fluctuating volatility impacts a position's net price.
The vega of long butterfly spreads with calls is negative. This implies that as volatility increases, the cost of a long butterfly spread decreases (and the spread loses money). The price of a lengthy butterfly spread increases as volatility decreases (and the spread makes money). Therefore, long butterfly spreads should be bought when volatility is "high" and expected to decrease.
Result of time
As expiration draws near, the time value element of an option's overall price declines. Time erosion is the term for this. The amount of temporal erosion that impacts a position's net price is indicated by the symbol "theta." If all other variables remain constant, long option positions have negative theta, which means they lose money from time erosion. In contrast, short option positions have positive theta, which means they profit from time erosion.
A lengthy butterfly spread with calls results in a gain. Theta so long as the stock price is between the two strike prices. But when expiration draws near, the theta turns negative if the stock price departs from this band.
Early assignment risk
In the United States, stock options may be exercised at any time during business hours, and owners of short stock option positions have little influence over the timing of the obligation. Therefore, while taking positions with short options, it is important to consider the risk of early assignment.
While there is no danger of early assignment with long calls in a long butterfly spread, there is a risk with short calls. In general, dividends and early stock options assignments are associated, and early assignment of short calls often occurs the day before the ex-dividend date. It is very likely that in-the-money calls whose time value is smaller than the payout will be assigned.
One hundred shares of the stock are sold short if one short call is assigned, but the long calls (with the lowest and highest strike prices) are left open. A short stock position can be liquidated in one of two ways if it is not desired. The first step is to buy 100 shares from the market. Second, the short 100-share position can be closed by exercising the lowest-strike long call. However, keep in mind that if a long call is exercised, its time value will be lost. In general, it is, therefore, better to acquire shares to cover a short stock position before selling a long call. The time value of the long call is recovered using this two-step process. A warning about commissions. Selling the long call after purchasing shares to cover the short stock position is only profitable if the commissions are lower than the time value of the long call.
The 200 shares are sold short, and the long calls (lowest and highest strike prices) stay open if both short calls are assigned. Again, there are two ways to end a short stock position if it is not desired.
Two hundred shares may be acquired on the open market, or the two long calls may be exercised.
However, as was previously said, it is typically preferable to acquire shares to settle the short stock position before selling the long calls because exercising a long call forfeits the time value. The warning is commissioned, as was already stated. Selling the long calls after purchasing shares to cover the short stock position is only profitable if the commissions are lower than the time value of the long calls.
However, keep in mind that the stock purchase date will be one day later than the date of the short sale, regardless of the technique used—purchasing shares and selling the long call or exercising the long call. Additional fees, such as interest fees and commissions, will be incurred due to this disparity. If there is insufficient account equity to sustain the stock position generated, assigning a short option may potentially result in a margin call.
At expiration, a potential position is created.
The position of a long butterfly spread with calls at expiration is determined by the correlation between the stock price and the spread's strike prices. The creation of a position is halted if the stock price falls below the lowest strike price, causing all calls to expire worthlessly.
The lowest strike long call is executed if the stock price is above the lowest and at or below the center strike. As a result, 100 shares are bought, creating a long position of 100 shares.
The lowest strike long call is exercised, and the two middle strike short calls are assigned if the stock price is above the center strike and at or below the highest strike. One hundred shares are bought, and 200 shares are sold. The result is a 100-share short position.
The two long calls (lowest and highest strikes) are exercised and the two short calls (middle strike) are assigned if the stock price is greater than the highest strike. Two hundred shares are bought, and 200 shares are sold. Despite incurring many stocks to buy and sell commissions, the end consequence is that there is no stake.
The following factors
A bull call spread and a bear call spread is another way to describe a long butterfly spread with calls. The bear call spread is the other short center-strike call paired with the long highest-strike call, and the bull call spread is the combination of the long lowest-strike call with one of the short center-strike calls.
The profit-loss graphic is supposed to be where the term "butterfly" from the strategy name came from. The peak of the long butterfly spread in the center of the diagram resembles a butterfly's body, and the horizontal lines that extend above and below the highest strike resemble a butterfly's wings.
Questions and Answers (FAQs)
A trading option known as a butterfly spread consists of various options on the same underlying security with the same expiration date but different strike prices. It is a limited-risk investment technique with a finite profit. To execute four trades in all, three strike prices are needed. Four call options, four put options, or a combination of both are available to investors.
What varieties of butterfly spreads are available?
There are numerous alternatives for butterfly spreads. Long call, short call, long put, short put, iron butterfly, and reverse iron butterfly are a few of them. In the butterfly spread strategy, call or put options with varying strike prices are held in long and short positions. Every option is a put for a butterfly put, and every option is a call for a butterfly called.
What distinguishes a straddle from a butterfly spread?
A straddle consists of two transactions involving the same asset, one of which carries a long risk and the other a short risk.
Butterfly spreads frequently result from adding more call or put options with varying strike prices to an existing open position.
The straddle method allows investors to make unlimited profits while exposing them to significant losses. Although the gains in the butterfly approach are constrained, the wings also help to limit the losses.
