What is a Long Straddle?
Buy to Open Call
Profits from a strong move higher.
Buy to Open Put
Profits from a strong move lower.
Mental model: “I do not know which direction the stock will move, but I believe the move will be large.”
Core structure
Both options usually use the same strike price and same expiration date, often near the current stock price.
| Leg | Action | Strike | Purpose |
|---|---|---|---|
| 1 | Buy to Open Call | Same strike | Upside exposure |
| 2 | Buy to Open Put | Same strike | Downside exposure |
When to use it
| Situation | Fit? | Why |
|---|---|---|
| Expect a very large move but direction is uncertain | Good fit | The call benefits from upside and the put from downside. |
| Major event could surprise the market | Potential fit | A large post-event move can make one side valuable. |
| Expect volatility to rise | Potentially favorable | Rising implied volatility can increase option values. |
| Expect stock to stay in a narrow range | Poor fit | Both options can lose value through time decay. |
| Options are extremely expensive due to high IV | Be careful | The stock may need an unusually large move just to break even. |
Worked example
Assume a stock trades near $100. You expect a major move after an event but do not know the direction.
| Leg | Action | Strike | Premium |
|---|---|---|---|
| 1 | Buy to Open $100 Call | $100 | Pay $4.00 = -$400 |
| 2 | Buy to Open $100 Put | $100 | Pay $3.50 = -$350 |
Total Premium Paid = $4.00 + $3.50 = $7.50/share
Total Cost = $7.50 × 100 = $750
Maximum loss and break-even points
Maximum Loss = Total Premium Paid = $750
The maximum loss occurs if the stock finishes exactly at the strike price at expiration, causing both options to expire with no intrinsic value.
Upper Break-even = Strike + Total Premium
Upper Break-even = $100 + $7.50 = $107.50
Lower Break-even = Strike - Total Premium
Lower Break-even = $100 - $7.50 = $92.50
What happens at expiration?
| Stock Price | Approximate Outcome | Meaning |
|---|---|---|
| $130 | Large profit | The call is worth about $30/share; the put expires worthless. |
| $110 | About +$250 | The call is worth $10/share; after $7.50 total premium, profit is about $2.50/share. |
| $107.50 | Upper break-even | The call's intrinsic value offsets total premium paid. |
| $100 | -$750 max loss | Both options expire at-the-money with no intrinsic value. |
| $92.50 | Lower break-even | The put's intrinsic value offsets total premium paid. |
| $85 | About +$750 | The put is worth $15/share; after $7.50 premium, profit is about $7.50/share. |
| $60 | Large profit | The put becomes deeply in the money. |
The main challenge: the stock must move enough
A Long Straddle is not profitable simply because the stock moves. The move must be large enough to overcome the combined premium paid for both options.
In the example, a move from $100 to $104 may feel meaningful, but the position could still lose money because the upper break-even is $107.50.
Time decay works against you
You own two options, so both positions lose time value as expiration approaches.
Important: if the expected move does not happen quickly enough, both the call and put can lose value at the same time.
Implied volatility matters a lot
Before the event
Implied volatility may rise, making both options expensive.
After the event
Implied volatility can collapse, reducing option values even if the stock moves.
This is why buying a straddle right before earnings can be difficult: the market may already be pricing in a large expected move.
Long Straddle vs. Long Strangle
| Feature | Long Straddle | Long Strangle |
|---|---|---|
| Call and put strikes | Same strike | Different strikes |
| Typical upfront cost | Higher | Lower |
| Move required | Smaller than strangle | Larger |
| Best use | Expect large move, want stronger sensitivity | Expect very large move, want cheaper entry |
Pros and cons
Pros
- Can profit from a large move in either direction.
- Maximum loss is limited to premium paid.
- No need to correctly predict direction.
- Can benefit from rising volatility.
Cons
- Expensive because you buy two options.
- Requires a large enough move to overcome total premium.
- Time decay hurts both legs.
- Volatility collapse can hurt the trade.
- Can lose 100% of premium if price stays near the strike.
How to close it
You can close both legs before expiration using Sell to Close orders.
Open: Buy to Open Call + Buy to Open Put.
Close: Sell to Close Call + Sell to Close Put.
Close: Sell to Close Call + Sell to Close Put.
Profit/Loss = Closing Value of Both Options - Total Premium Paid
Common mistakes
- Buying just because a major event is approaching without checking implied volatility.
- Ignoring the expected move already priced into options.
- Choosing an expiration that is too short.
- Assuming any move will be profitable.
- Holding through an event without understanding volatility crush.
- Failing to calculate both break-even points before entering.
Beginner checklist
| Check | Question |
|---|---|
| ☐ Expected move | Do I expect a move larger than the total premium implies? |
| ☐ Direction uncertainty | Am I genuinely unsure whether the move will be up or down? |
| ☐ Total premium | Can I afford to lose 100% of the amount paid? |
| ☐ Break-evens | What are the exact upper and lower break-even prices? |
| ☐ Volatility | Is implied volatility already extremely high? |
| ☐ Expiration | Does the option give enough time for the expected move? |
| ☐ Liquidity | Are both options liquid with reasonable spreads? |
| ☐ Exit plan | Will I close before the event, after the move, or hold to expiration? |
Key takeaway
Long Straddle = Buy Call + Buy Put at the Same Strike and Expiration
Use it when you expect a large move but are uncertain about direction.
The key trade-off is simple: you pay a relatively high premium for the ability to profit from either a large upside or downside move.
