A long straddle buys a call and a put with the same strike price and expiry. It profits if the underlying moves far enough in either direction to cover the total premium paid, so it is a bet on a big move rather than a direction. The maximum loss is the premium paid. A short straddle sells both and has unlimited risk.
A straddle is for the trader who expects a big move but does not know which way. It is a simple structure with expensive pitfalls: you pay for two options, and time decay works against you every day. Here is how it works, with numbers.

The long straddle
Build it: buy one call and one put on the same stock, with the same strike price (usually at the money) and the same expiry.
You profit when the stock moves far enough in either direction that the gain on one option is bigger than the total premium paid for both.
Break-even points:
- Upper: strike + total premium
- Lower: strike − total premium
Maximum loss: the total premium paid, which happens if the stock closes exactly at the strike at expiry. Maximum profit: unlimited on the upside, and large (to zero) on the downside.
A worked example
A stock trades at $100 and reports earnings next week. You buy a 30-day $100 call for $3.00 and a $100 put for $2.80. Total cost: $5.80 per share, or $580 for one contract of 100 shares.
| Stock at expiry | Call value | Put value | Profit or loss |
|---|---|---|---|
| $100 | $0 | $0 | −$580 (max loss) |
| $105 | $500 | $0 | −$80 |
| $106 | $600 | $0 | +$20 |
| $90 | $0 | $1,000 | +$420 |
| $120 | $2,000 | $0 | +$1,420 |
Break-evens: $100 + $5.80 = $105.80 and $100 − $5.80 = $94.20. The stock must move more than about 5.8% either way by expiry, just to break even. Premiums here are illustrative round numbers, not market quotes.

- You pay for time. Both options lose value every day (time decay, "theta"). If the stock sits still, you lose.
- Implied volatility is priced in. Before earnings, options already price in a big move. If the actual move is smaller than the market expected, you can lose money even if the stock moves in one direction. This is called a volatility crush.
- Two commissions and two spreads. You are paying the bid-ask spread on both legs.
The strategy only pays when the move is bigger than what the options already price in.
When traders use it
- Ahead of known events such as earnings, regulatory decisions or product launches, when a big move is likely but the direction is not.
- When implied volatility is low and a breakout seems close.
- As a defined-risk way to play a volatile asset, since you cannot lose more than the premium.
The short straddle
A short straddle sells a call and a put at the same strike. You collect the premium and profit if the stock stays near the strike. The trade has unlimited risk on the upside and large risk on the downside, and it needs margin. It is not suitable for beginners. If you want limited risk, a short iron butterfly or iron condor caps the loss with extra long options.
Straddle vs strangle
A strangle buys an out-of-the-money call and an out-of-the-money put at different strikes. It costs less than a straddle but needs a bigger move to profit.
| Straddle | Strangle | |
|---|---|---|
| Strikes | Same (usually at the money) | Different (out of the money) |
| Cost | Higher | Lower |
| Move needed to profit | Smaller | Larger |
Risk rules
- Size small. The premium can go to zero, so treat it as a defined loss. See position sizing.
- Check implied volatility. Compare it with the stock's usual range, and with how much the options imply for the move.
- Know the exit plan. Decide before entry when to close if the stock has not moved, rather than holding to expiry.
- Consider the calendar. See the economic calendar guide and earnings dates.
- Learn it on paper first. See paper trading. For related structures, read options vs stocks and the wheel strategy.
FAQ
What is a straddle in options?
A strategy that buys (or sells) a call and a put with the same strike and expiry. A long straddle profits from a large move in either direction.
What is the maximum loss on a long straddle?
The total premium paid for the call and the put. That happens if the stock closes at the strike at expiry.
When is a straddle profitable?
When the stock moves beyond the upper or lower break-even, meaning the strike plus or minus the total premium, by more than the options had already priced in.
Is a straddle a good strategy for earnings?
It can be, but options are usually expensive before earnings and implied volatility often drops afterward, so many straddles lose even when the stock moves.
What is the difference between a straddle and a strangle?
A straddle uses the same strike for both options, and a strangle uses different out-of-the-money strikes. A strangle is cheaper but needs a bigger move.
