Straddle vs Strangle - Which Volatility Trade Fits?

In this lesson
Compare a long straddle and a long strangle on the same stock, and choose between them based on the size of the move you expect and how much premium you are willing to risk.
The difference between a straddle and a strangle is where the strikes sit: a straddle buys a call and a put at the same strike, usually at the money, while a strangle buys an out-of-the-money put and an out-of-the-money call at two different strikes. The straddle costs more and needs a smaller move; the strangle costs less and needs a bigger one.
Both are bets that a stock will move a lot, in either direction, before expiration. Long Straddle and Long Strangle built each one on XYZ at $50. This lesson puts the two side by side, with the same model inputs, so the trade-off is easy to see.
How do a straddle and a strangle compare?
Worked example
XYZ 50 straddle against the XYZ 45/55 strangle
XYZ trades at $50, 30 days to expiration. Prices are Black-Scholes model values at 30% implied volatility and a 4.5% interest rate. Figures are per share x 100, before fees and bid-ask spreads.
Illustrative and hypothetical. The ticker and prices are invented for teaching, and the figures exclude commissions, fees, margin interest and taxes, which reduce real results. Past or hypothetical outcomes do not indicate future results.

The chart shows the shape of the choice. The straddle's V dips deeper, to -$343, but crosses zero sooner. The strangle's line has a flat floor at -$53, then only starts rising at the strikes. Beyond the strikes, the two lines run parallel, with the straddle $210 ahead at every price: $500 of extra intrinsic value (the $5 between the strikes, x 100) minus the $290 it cost to buy that head start.
Which one needs a bigger move?
The strangle, every time, for the same stock and expiration. Its options start out of the money, so the stock has to reach a strike before either leg has any value at expiration, and then go further still to cover the premium.
In the example, the straddle profits at expiration once XYZ moves more than $3.43 from $50. The strangle needs more than $5.53. If you expect XYZ to finish around $54 or $46, the straddle wins a little and the strangle loses everything.
Which one costs more to hold?
Measured in dollars, the straddle. Measured as a share of what you paid, the strangle.
In the calculator's pricing model, the straddle starts out losing about $5.70 a day to time decay and the strangle about $2.94. But after 15 days with XYZ still at $50 and IV unchanged, the straddle keeps about 71% of its value ($243 of $343) and the strangle only about 26% ($14 of $53). Values before expiration add up each leg's model price rounded to the cent, which is how the calculator's Auto premiums show them.

Value after 15 days, XYZ still at $50
That is the strangle's hidden cost. If the move is slow to arrive, or arrives late in the trade, a strangle may have little value left to sell. A straddle bought at the money holds more of its value through a quiet stretch, though it has more dollars to lose.
Both are long vega. An immediate 10-point rise in implied volatility lifts the straddle by about $114 and the strangle by about $69 in this example. A 10-point drop takes about $114 from the straddle and $43 from the strangle, which is then worth only about $10: a cheap option cannot lose more than it is worth.
How do you choose between a straddle and a strangle?
Start from the move you expect, then fit the strikes to it.
- You expect a move, but not a huge one. A straddle's closer break-evens give it the better chance of profiting.
- You expect a very large move, or want to risk fewer dollars. A strangle costs a fraction of the straddle and still gains $100 per dollar once the stock clears a strike. Beyond the strikes it stays $210 behind the straddle on the same stock, although between about $47.10 and $52.90 at expiration the strangle loses less.
- You are unsure when the move comes. A straddle keeps more of its value through quiet days, which leaves more time for the move.
- Size the trade by dollars at risk, not by number of contracts. Six strangles cost about as much as one straddle ($318 against $343) and gain six times as much per dollar beyond the break-evens, but all six expire worthless across a $10 range.
That last point is where many traders get into trouble. A cheap premium can tempt you into a bigger position than you would ever take in a straddle. The Course 1 lesson Position Sizing covers how to set a dollar limit first.
Does the same comparison hold when you sell them?
Mostly in reverse, with one serious addition: sold, both have undefined risk, because the short call has no ceiling on its loss. Short Straddle and Short Strangle cover that side of the trade.
Check your understanding
XYZ finishes at $54. What are the results of the 50 straddle ($3.43) and the 45/55 strangle ($0.53)?
Show answer
The straddle makes $57: the call is worth $4.00, and ($4.00 - $3.43) x 100 = $57. The strangle loses its full $53, because $54 is between its strikes.
Beyond the strikes, why is the straddle always $210 ahead of the strangle in this example?
Show answer
Above $55 or below $45, both positions gain $100 per dollar. The straddle's option is $5 deeper in the money, worth $500 more, and it cost $290 more ($343 - $53). $500 - $290 = $210.
After 15 days with the stock unchanged, which position has lost the larger share of its value?
Show answer
The strangle. It fell from $53 to about $14, keeping about 26%; the straddle fell from $343 to about $243, keeping about 71%.
Key takeaways
- A straddle buys a call and a put at one strike; a strangle buys them at two strikes further out.
- The straddle costs more ($343 against $53 here) and needs a smaller move (about 6.9% against 11.1%).
- The strangle loses its whole premium across a range of prices; the straddle only at one price.
- Time decay takes more dollars from a straddle but a larger share of a strangle's value.
- Sold, both have undefined risk.
Common questions
Which is better, a straddle or a strangle?
Neither is better in general. A straddle costs more but needs a smaller move and keeps more of its value if the move is slow to come. A strangle costs less but needs a bigger move and loses its whole premium across a wider range of prices.
Is a strangle riskier than a straddle?
A long strangle risks fewer dollars, because it costs less. But it is more likely to lose all of them, since every finish between its two strikes is a total loss. Which one is riskier depends on whether you measure dollars at stake or the chance of losing them.
Why is a straddle more expensive than a strangle?
Both of a straddle's options are at the money, where extrinsic value is highest. A strangle's options are out of the money, so each is cheaper, and the further out the strikes are, the cheaper the strangle.
Do straddles and strangles have the same risk when you sell them?
Both have undefined risk when sold, because the stock has no limit on how far it can rise, so the short call's loss has none either. The short straddle collects more premium and is tested sooner; the short strangle collects less and has a wider range where it keeps everything.
