Straddle and Strangle
A long straddle buys a call and a put with the same strike and expiry; a strangle uses an out-of-the-money call and put, which costs less. Both profit from a big move in either direction and lose if price stays still. Selling them is the opposite bet.
Sometimes you are sure a big move is coming but not which way — earnings, a court ruling, a central-bank decision. Straddles and strangles let you bet on the size of the move rather than its direction by holding a call and a put at once. Sellers take the other side, betting the market stays calm. This entry explains both strategies, from the buyer's and the seller's side, with break-evens.

Straddles and strangles in plain words
A long straddle buys a call and a put with the same strike and expiry, so it profits if the stock makes a big move either up or down.1
A strangle does the same with a call strike above the put strike, usually both out of the money: it brings in less premium than a straddle and needs a larger move.2
Selling either one collects both premiums and bets on a steady price, but the potential loss is unlimited on the upside.3
How to set up a long straddle or strangle, step by step
Expect a big move
Often around earnings or major news. See Earnings.
Check implied volatility
If options are already expensive, the move must be even bigger. See Implied Volatility.
Choose strikes
Straddle: both at the money. Strangle: call above, put below the price.
Buy both options
Same expiry; total cost = both premiums. See Option Premium.
Work out break-evens
Strike ± total premium (straddle); call strike + premium and put strike − premium (strangle).
Exit before decay bites
Time decay hurts long straddles every day. See Option Greeks.
Worked examples
Example 1 — A long straddle into earnings
+$700Stock at $100. You buy the $100 call for $4 and the $100 put for $4. After earnings it jumps to $115.
| Total cost | ($4 + $4) × 100 = $800 |
| Call value | ($115 − $100) × 100 = $1,500 |
| Profit | $1,500 − $800 = $700 |
| Break-evens | $92 and $108 |
The best outcome for a long straddle is a big move either way; the worst is a steady price with falling volatility.1
Example 2 — The stock barely moves
−$700Same straddle, but the stock closes at $101 at expiry.
| Call value | $1 × 100 = $100 |
| Put value | $0 |
| Loss | $100 − $800 = −$700 |
The buyer's maximum loss is the two premiums paid, reached if the stock sits right at the strike.1
Example 3 — Selling a strangle
+$220Stock at $60. You sell the $65 call for $1.20 and the $55 put for $1.00. At expiry the stock is $58.
| Premium collected | ($1.20 + $1.00) × 100 = $220 |
| Both options expire | Kept in full |
| Break-evens | $52.80 and $67.20 |
A short strangle profits if price and volatility stay steady; its gain is limited to the premium and its loss is unlimited above the call strike.2
Straddle vs strangle (long)
| Aspect | Straddle | Strangle |
|---|---|---|
| Strikes | Same (at the money) | Call above, put below |
| Cost | Higher | Lower |
| Move needed | Smaller | Larger |
| Max loss | Both premiums | Both premiums |
When traders use them
Earnings and events
Betting on a big reaction of unknown direction.
Cheap volatility
Buying when implied volatility looks low.
Selling calm
Short strangles collect premium in quiet markets — with large tail risk.
Hedged versions
Adding wings turns a short strangle into an Iron Condor with capped risk.
Advantages and disadvantages
Advantages
- Profit without picking direction (long).
- Defined maximum loss for the buyer.
- Strangles are cheaper than straddles.
Disadvantages
- Long positions bleed from time decay.
- Volatility often collapses after the event. See Implied Volatility.
- Short versions carry unlimited risk.

Read as far as you need. Each level builds on the one before it.
Break-even arithmetic
Beginner
For a long straddle, add and subtract the total premium from the strike: a $100 straddle costing $8 breaks even at $92 and $108 at expiry. The stock must move more than 8% just to profit.
The volatility crush
Intermediate
Option prices before earnings already include a big expected move. When the news is out, implied volatility usually drops sharply, so a straddle can lose money even after a decent move. See Implied Volatility.
The short side's risk
Advanced
A short straddle's worst cases are the stock rising without limit or falling to zero.3 Brokers require high option approval and margin, and many traders cap the risk with an Iron Condor instead. See Naked Options.
Common mistakes
Buying after volatility has spiked
You pay for a move the market already expects.
Holding too long
Time decay erodes a long straddle daily.
Selling strangles without a plan
One gap can wipe out months of premium.
Ignoring assignment
Short options can be exercised early. See Exercise and Assignment.

- Buyers risk only the premiums; sellers face unlimited risk.
- Implied volatility decides whether they are cheap or expensive.
- Time decay works against buyers and for sellers.
