Long Strangle Payoff Diagram
Investment Education, Research & Tools for Smarter Decisions.
A long strangle buys an out-of-the-money call and an out-of-the-money put at different strikes on the same expiration. The payoff diagram shows the strategy profits from large moves in either direction while costing less than a straddle, since both options are out of the money and require a wider breakeven range to become profitable.
Direct answer: A long strangle buys an OTM put and an OTM call on the same expiration, with the put strike below and the call strike above the current stock price. The maximum loss equals the total debit paid and occurs when the stock finishes between the two strikes. Profit is theoretically unlimited on the upside and substantial on the downside once the stock moves past either breakeven point.
How a Long Strangle Is Constructed
A long strangle consists of two legs purchased simultaneously on the same underlying and the same expiration date:
- Long OTM put: Strike price below the current stock price.
- Long OTM call: Strike price above the current stock price.
Both options are bought (long), so the trader pays a net debit. Because both strikes are out of the money at initiation, each option costs less than an at-the-money option, which is what makes a strangle cheaper than a straddle. The trade-off is that the stock must move further before either leg gains intrinsic value.
As a hypothetical example: suppose a stock trades at $50. A trader buys a $45 put for $1.20 and a $55 call for $0.80. Total debit is $2.00 per share, or $200 per contract.
The Shape of the Payoff Diagram
The long strangle payoff diagram has three distinct zones:
Flat loss zone between the strikes
If the stock expires anywhere between the put strike and the call strike, both options expire worthless. The trader loses the entire premium paid. In the example above, any close between $45 and $55 results in a $2.00 loss per share. This flat bottom is the defining visual characteristic that separates a strangle from a straddle, which has a pointed V-shape with no flat zone.
Rising profit below the put strike
Below the put strike, the long put gains intrinsic value as the stock falls. The diagram slopes upward (as viewed from a loss perspective, the loss shrinks and then turns to profit). The slope reflects the put's delta increasing toward 1.0 as the stock drops further into the money. Profit is theoretically capped only by the stock reaching zero.
Rising profit above the call strike
Above the call strike, the long call gains value as the stock rises. This leg has unlimited upside, since there is no theoretical ceiling on how high a stock can trade. The diagram slopes upward without bound above the upper breakeven.
Calculating the Two Breakeven Prices
A long strangle has exactly two breakeven prices at expiration, one on each side of the current stock price:
- Lower breakeven: Put strike price minus the total net debit paid.
- Upper breakeven: Call strike price plus the total net debit paid.
Using the $45/$55 strangle with a $2.00 debit:
- Lower breakeven: $45 minus $2.00 equals $43.00
- Upper breakeven: $55 plus $2.00 equals $57.00
The stock must close below $43 or above $57 at expiration for the position to be profitable at expiration. The total distance from the current stock price to either breakeven is wider than a comparable straddle because the strikes themselves are already offset from the stock price.
Long Strangle vs. Long Straddle
Both the long strangle and long straddle are long volatility strategies that profit from large price moves in either direction. The key differences are cost, breakeven width, and the shape of the payoff diagram:
| Feature | Long Straddle | Long Strangle |
|---|---|---|
| Strike selection | Both at the money (same strike) | OTM call, OTM put (different strikes) |
| Net debit | Higher (ATM options are more expensive) | Lower (OTM options cost less) |
| Breakeven range | Narrower (closer to current price) | Wider (farther from current price) |
| Payoff diagram shape | V-shape (pointed at ATM strike) | V-shape with flat loss zone between strikes |
| Implied move needed | Smaller move required | Larger move required |
Traders choose a strangle over a straddle when they expect a very large move but want to reduce the capital at risk. The strangle is cheaper, but it requires the underlying to move substantially to generate profit by expiration.
Implied Volatility and the Long Strangle
Because a long strangle holds two long options, it has positive vega. A rise in implied volatility after entry increases the value of both the call and the put, improving the position's value even before the stock moves. This characteristic makes the strangle attractive ahead of events expected to increase volatility.
The opposite effect, called volatility crush, is the most common reason strangle buyers lose money on correct directional calls. After a major event such as an earnings announcement, implied volatility typically collapses sharply. Even if the stock moves in a favorable direction, the drop in IV can reduce the option premiums faster than the intrinsic value gained, leaving the trader with a net loss.
This is why entering a strangle immediately before a high-IV event (when premiums are inflated) carries meaningful risk. The anticipated move may already be priced into the options. Checking the implied move (approximately equal to the at-the-money straddle price) against the historical average move can help assess whether the options are fairly priced relative to the expected outcome.
FAQ
What is a long strangle in options trading?
A long strangle is an options strategy that buys an out-of-the-money call and an out-of-the-money put on the same underlying asset with the same expiration date but at different strike prices. The call strike is above the current stock price and the put strike is below it. The strategy profits from a large move in either direction.
What does the long strangle payoff diagram look like?
The long strangle payoff diagram has a V-shape with a flat bottom. Between the two strike prices, the position loses the entire premium paid (maximum loss). Below the put strike and above the call strike, the diagram slopes upward, with profit accelerating as the stock moves further from the strikes. The shape resembles a wide U or a V with a flat section in the middle.
How do you calculate the breakeven points on a long strangle?
A long strangle has two breakeven prices. The lower breakeven equals the put strike minus the total net debit paid. The upper breakeven equals the call strike plus the total net debit paid. For example, if you buy a $45 put and a $55 call for a combined $3 debit, the lower breakeven is $42 and the upper breakeven is $58.
What is the maximum loss on a long strangle?
The maximum loss on a long strangle is the total net debit paid to enter the position. This occurs when the stock price is anywhere between the two strike prices at expiration, causing both the call and the put to expire worthless. The loss is limited to the premium paid, unlike short strategies where losses can be much larger.
How does a long strangle differ from a long straddle?
Both strategies profit from large moves in either direction, but a long straddle uses at-the-money options for both the call and the put at the same strike, while a long strangle uses out-of-the-money options at two different strikes. The strangle costs less because OTM options carry less intrinsic value, but it requires a larger stock move to become profitable. The straddle starts profiting with smaller moves but at a higher initial cost.
When is a long strangle most likely to profit?
A long strangle profits when the underlying stock makes a large move before expiration, either well above the call strike or well below the put strike. Common situations include before earnings announcements, FDA decisions, major economic data releases, or other binary events where a big price swing is anticipated but the direction is uncertain. Rising implied volatility after entry also increases the value of both legs.
What is the effect of implied volatility on a long strangle?
A long strangle has positive vega, meaning it benefits from increases in implied volatility. When IV rises after you enter the position, both the call and the put increase in value. Conversely, if IV falls (volatility crush, which commonly occurs after earnings announcements), both options lose value even if the stock moves, which can turn a seemingly profitable trade into a loss. Buying a strangle before a high-IV event carries the risk of IV crush.
