What Is a Strangle?
A strangle is a volatility strategy similar to a straddle, but with a key difference: instead of buying options at the same strike, you buy an out-of-the-money call and an out-of-the-money put with different strike prices. The call strike is above the current stock price, and the put strike is below it. Because both options are out of the money, the strangle costs less than a straddle.
The lower cost comes with a trade-off: the stock needs to move further for the strangle to profit. The breakeven points are wider because you are starting from OTM positions on both sides. However, if the stock makes a very large move — a gap of 15% or more — the strangle can generate outsized returns because you paid less for the position.
Strangles are popular around high-impact events where a large price swing is expected but the direction is uncertain. They are also used by traders who want exposure to a big move but want to minimize their upfront cost. The defined-risk nature of a long strangle (maximum loss is the total premium) makes it accessible to traders of all experience levels.
How to Use This Calculator
The calculator takes the call strike, put strike, both premiums, and the number of contracts to produce a complete payoff analysis.
Call Strike and Put Strike
Enter the strike prices for both options. The call strike should be above the current stock price, and the put strike should be below it. The distance between the strikes and the current price determines how OTM each option is, which affects both the cost and the required move for profitability.
Call Premium and Put Premium
Enter the premium for each option separately. The call premium is typically lower than the put premium for the same distance from the stock price due to put-call skew. The calculator uses both premiums to compute the total cost and breakevens.
Number of Contracts
Enter how many strangles you plan to trade. Each strangle consists of one call and one put. The calculator scales the output by the number of contracts.
Reading the Output
The calculator shows your total cost, upper breakeven, lower breakeven, maximum loss, and maximum profit. The payoff diagram shows the profit and loss across a range of stock prices at expiration.
Formula
The key formulas for a long strangle are:
Total Cost = Call Premium + Put Premium
Upper Breakeven = Call Strike + Total Cost
Lower Breakeven = Put Strike — Total Cost
Max Loss = Total Cost
Max Profit = Unlimited (upside) / Put Strike — Lower Breakeven (downside)
Examples
Example 1: Long Strangle Before FDA Decision
A biotech stock is trading at $50. You buy a $55 call for $2.00 and a $45 put for $1.80, for a total cost of $3.80 per share ($380 per strangle). The upper breakeven is $58.80 and the lower breakeven is $41.20. If the stock jumps to $65, your profit is $65 — $58.80 = $6.20 per share ($620 per strangle). If the stock drops to $35, your profit is $41.20 — $35 = $6.20 per share. Either way, a large move generates a profit.
Example 2: Short Strangle Income
You sell a strangle on a stable stock: $55 call for $1.50 and $45 put for $1.30, collecting $2.80 total ($280 per strangle). If the stock stays between $45 and $55 at expiration, both options expire worthless and you keep the $280. Your profit zone is $10 wide and you collect $280 for allowing the stock to fluctuate within that range.
Example 3: Comparing Strangle to Straddle
Same stock at $100. A $100 straddle costs $9.50 (breakevens at $90.50 and $109.50). A strangle using a $110 call ($3.00) and a $90 put ($2.80) costs $5.80 (breakevens at $84.20 and $115.80). The strangle is cheaper ($5.80 vs $9.50) but requires a bigger move. The straddle has closer breakevens but costs more.
Tips
Buy Strangles When IV Is Low
Strangles are cheapest when implied volatility is low relative to its historical range. If you can buy a strangle when IV is in the bottom 20% of its one-year range, you pay less and need a smaller move to profit.
Avoid Selling Strangles Without Stop Losses
Short strangles have theoretically unlimited risk. Always use stop losses or convert the position to an iron condor by buying OTM wings to cap your maximum loss. Never sell strangles on volatile stocks or during uncertain markets.
Consider the IV Crush After Events
If you buy a strangle before an event, implied volatility typically drops sharply after the event. This means the options lose value even if the stock moves, because the volatility component deflates. You need the stock to move enough to overcome both the premium cost and the IV crush.
Scale Position Size to Risk Budget
The maximum loss on a long strangle is the total premium paid. Use this to size your position. If the strangle costs $380 per contract and you risk 2% of a $25,000 account ($500), you should trade no more than one contract.
FAQ
What is a strangle?
A strangle is an options strategy where you buy an out-of-the-money call and an out-of-the-money put on the same stock with the same expiration date but different strike prices. The call strike is above the current stock price and the put strike is below it. Because both options are out of the money, a strangle is cheaper than a straddle. The trade-off is that the stock needs to move further to reach either breakeven.
How is a strangle different from a straddle?
A straddle uses the same strike for both the call and the put (usually at-the-money), while a strangle uses different strikes with both options out of the money. The strangle is cheaper to enter because OTM options cost less than ATM options. However, the strangle requires a bigger stock move to profit because the breakevens are wider.
When should I use a long strangle?
A long strangle works best when you expect a very large move in the stock but are uncertain about the direction. It is especially useful before high-impact events like earnings, FDA decisions, or major announcements where the stock could gap significantly in either direction.
What are the breakeven points for a long strangle?
A long strangle has two breakeven points. The upper breakeven is the call strike plus the total premium paid. The lower breakeven is the put strike minus the total premium paid. The stock must move beyond these points for the strangle to be profitable at expiration.
What is the maximum loss on a long strangle?
The maximum loss on a long strangle is the total premium paid for both the call and the put. This occurs when the stock closes between the two strike prices at expiration, causing both options to expire worthless. The loss is limited to the premiums, making this a defined-risk strategy.
What is a short strangle?
A short strangle is the opposite of a long strangle: you sell both an OTM call and an OTM put at different strikes. You collect two premiums. The strategy profits if the stock stays between the two strike prices at expiration. The risk is theoretically unlimited if the stock moves far beyond either strike.
How does implied volatility affect strangles?
Implied volatility is crucial for strangle profitability. When you buy a strangle, high IV means you pay more for both options, requiring a bigger move to profit. When you sell a strangle, high IV means you collect more premium, giving you a wider profit zone. Strangles are most profitable to sell when IV is high and likely to fall.
What strike selection should I use for a strangle?
For a long strangle, choose OTM options with strikes that reflect your expectation of how far the stock will move. A common approach is to use strikes that are 5-10% away from the current stock price on each side. Closer strikes cost more but have tighter breakevens. Further strikes cost less but require a bigger move.
Can I lose more than my premium on a long strangle?
No. The maximum loss on a long strangle is limited to the total premium paid for both options. You cannot lose more than you paid, regardless of how the stock moves. This defined-risk property is a key advantage of buying strangles versus selling them.
How do I close a strangle before expiration?
You can close a strangle before expiration by selling both the call and the put in the market. The closing price depends on the remaining time value, implied volatility, and the stock position relative to the strikes. The net difference between your entry cost and exit proceeds is your profit or loss.
