What is a Long Strangle?
Profits from a strong move higher.
Profits from a strong move lower.
Core structure
The call strike is above the current stock price and the put strike is below it. Both options use the same expiration.
| Leg | Action | Typical Strike | Purpose |
|---|---|---|---|
| 1 | Buy to Open Call | Above current stock price | Upside exposure |
| 2 | Buy to Open Put | Below current stock price | Downside exposure |
When to use it
| Situation | Fit? | Why |
|---|---|---|
| Expect a very large move, direction uncertain | Good fit | Either the call or put can become valuable. |
| Want lower upfront cost than a Straddle | Good fit | Both options are typically out of the money. |
| Expect volatility to increase | Potentially favorable | Rising implied volatility can increase option values. |
| Expect only a small move | Poor fit | The trade needs a larger move than a straddle. |
| Options already price an extreme move | Be careful | Break-even points can be very far away. |
Worked example
Assume a stock trades at $100. You expect a very large move but do not know the direction.
| Leg | Action | Strike | Premium |
|---|---|---|---|
| 1 | Buy to Open Call | $110 Call | Pay $2.50 = -$250 |
| 2 | Buy to Open Put | $90 Put | Pay $2.00 = -$200 |
Maximum loss
If the stock finishes between $90 and $110 at expiration, both options can expire worthless and the full premium may be lost.
What happens at expiration?
| Stock Price | Approximate Outcome | Meaning |
|---|---|---|
| $130 | Large profit | The $110 call is worth about $20/share. |
| $115 | About +$50 | The call is worth $5/share, slightly above the total $4.50 cost. |
| $114.50 | Upper break-even | The call offsets the total premium. |
| $100 | -$450 max loss | Both options expire worthless. |
| $90 | -$450 max loss | The put is at the strike and has no intrinsic value. |
| $85.50 | Lower break-even | The put offsets the total premium. |
| $75 | Large profit | The put becomes deeply in the money. |
Why it is cheaper than a Straddle
Both options in a Long Strangle are usually out of the money, so the total premium is lower than buying an at-the-money call and put.
Long Strangle vs. Long Straddle
| Feature | Long Strangle | Long Straddle |
|---|---|---|
| Strikes | Different strikes | Same strike |
| Typical cost | Lower | Higher |
| Move required | Larger | Smaller |
| Maximum loss | Total premium paid | Total premium paid |
| Best use | Expect a very large move | Expect a large move |
Time decay and volatility
Works against both purchased options. If the expected move is delayed, both can lose value.
Rising IV can help both options; falling IV can hurt both at the same time.
How to choose strikes
| Choice | Typical Effect |
|---|---|
| Strikes closer to current price | Higher premium, but smaller move required. |
| Strikes farther away | Lower premium, but larger move required. |
| Symmetric strikes | More balanced exposure to either direction. |
| Asymmetric strikes | Can reflect a belief that one direction is more likely or more explosive. |
Pros and cons
- Can profit from a large move in either direction.
- Cheaper than a comparable Straddle.
- Maximum loss is limited to premium paid.
- No need to predict direction correctly.
- Can benefit from rising volatility.
- Requires a larger move than a Straddle.
- Both options suffer time decay.
- Volatility crush can hurt both legs.
- Can lose 100% of premium.
- Break-even prices may be far away.
How to close it
Close: Sell to Close Call + Sell to Close Put.
You can close early after a large move or volatility increase; you do not need to hold to expiration.
Common mistakes
- Choosing strikes so far away that the required move is unrealistic.
- Focusing only on the cheap premium and ignoring break-even points.
- Buying immediately before earnings without checking implied volatility.
- Ignoring time decay on both legs.
- Assuming any large-looking move will be enough.
- Entering without a clear exit plan.
Beginner checklist
| Check | Question |
|---|---|
| ☐ Expected move | Do I expect a move large enough to exceed either break-even? |
| ☐ Total premium | Can I afford to lose the entire premium? |
| ☐ Call strike | How far must the stock rise? |
| ☐ Put strike | How far must the stock fall? |
| ☐ Volatility | Is IV already unusually high? |
| ☐ Expiration | Is there enough time for the move? |
| ☐ Liquidity | Are both options liquid? |
| ☐ Exit plan | When will I take profit or cut the trade? |
Key takeaway
Use it when you expect a very large move but do not know the direction.
The central trade-off is: lower cost than a Straddle, but a larger move is required to make money.
