Long Straddle Options Strategy Guide
By OptionClaws, VirWare LLC · Updated 2026-08-23
A long straddle buys a call and a put at the same strike, usually at the money, in the same expiration. You profit if the stock moves far enough in either direction to cover the combined premium, and you lose if it sits still. It is a pure bet on the size of the move, not its direction, which makes it the standard trade around earnings, regulatory decisions, and other binary events. The catch is that the market prices those events too: the straddle's cost is roughly the expected move, so you need the stock to beat expectations, not just move.
Key takeaways
- Buy a call and a put at the same strike and expiration, usually at the money
- Max loss is the total debit; profit is unlimited on the upside and large on the downside
- Two breakevens: strike plus debit and strike minus debit
- You are betting the stock moves more than the options market has priced in
When it makes sense
- A known catalyst is coming and you expect a larger move than the options imply
- Implied volatility is low relative to the stock's realized movement, so the straddle is cheap
- You have a view on magnitude but not direction
- You want to buy the event before implied volatility ramps into it, rather than the day before
How it works
Buy one call and one put at the same at-the-money strike and expiration. The sum of the two premiums is the debit and the maximum loss. At expiration one option is worthless and the other is worth the distance the stock has moved from the strike, so profit is that distance minus the debit. Upper breakeven is strike plus debit; lower breakeven is strike minus debit. The straddle price is also a market forecast: a $6.20 straddle on a $100 stock says the market expects a move of about 6% by expiration, so that is the bar you have to clear.
Risk and reward
Maximum loss: the total debit, realized if the stock finishes exactly at the strike. Maximum profit: unlimited on the upside; on the downside it is the strike minus the debit, times 100, reached if the stock goes to zero. Breakevens: strike plus and minus the debit. Partial losses are the common outcome, since the stock often moves some but not enough. The probability of finishing outside the breakevens is usually well under 50%; the trade's edge, when it has one, comes from moves that exceed the implied range by a wide margin.
Greeks and volatility
Delta starts near zero and grows in whichever direction the stock moves, because gamma is strongly positive: the straddle gets longer on rallies and shorter on drops on its own. Theta is sharply negative, the largest per-day decay of any common structure, and it accelerates into expiration. Vega is strongly positive, so rising implied volatility raises the straddle's value even before the stock moves, and the reverse is the famous IV crush: after an earnings report, implied volatility collapses, and a straddle can lose money even when the stock moves several percent.
Managing the trade
Decide in advance whether you are trading the event or trading the run-up. Buying a straddle a week or two ahead of earnings and selling it just before the report captures the rise in implied volatility without taking the crush. Holding through the report needs the move to beat the implied move after the crush. Scalping gamma (selling some stock after a rally, buying after a drop, to reset delta to zero) can pay for theta on volatile names. Both legs can be exercised early at your discretion, but it is almost never optimal; close to capture time value.
Worked example
Stock at $100, earnings in 12 days. Buy the 30-day $100 call for $3.20 and the $100 put for $3.00, a $6.20 debit ($620), which implies a roughly 6% expected move. Breakevens are $106.20 and $93.80. If the stock gaps to $112 after the report the call is worth $12.00: you sell the straddle for about $1,200, a $580 profit. If it moves to $104 the call is worth $4.00 and you lose $220. If it finishes at $100 you lose the full $620.
What to screen for
Screen straddles by the full loss range between the breakevens measured in the stock's daily ATRs (a narrower range is cheaper relative to how the stock moves), by implied volatility rank (lower means the straddle is cheap), and by earnings date so you know whether the event is inside the window. Cap the debit to size positions and require tight spreads on both legs, since you pay the bid-ask on two options in and out.

Frequently asked questions
- What is the breakeven of a long straddle?
- Two of them: the strike plus the total debit on the upside, and the strike minus the debit on the downside. A $100 straddle bought for $6.20 breaks even at $106.20 and $93.80.
- Why did my straddle lose money after earnings when the stock moved?
- Implied volatility crush. Pre-earnings implied volatility is elevated; after the report it collapses, and if the stock's move was smaller than the options had priced, both legs lose value even though one gained intrinsic worth.
- What is the implied move and how does it relate to the straddle?
- The at-the-money straddle price, as a percent of the stock price, is the market's estimate of the expected move through expiration. A straddle profits at expiration only if the actual move exceeds that estimate.
- Long straddle or long strangle?
- A strangle uses out-of-the-money strikes, so it costs less but needs a bigger move to profit. A straddle costs more, starts gaining sooner, and loses less if the stock moves moderately.
