Strangle

What is a strangle?

A strangle is an options strategy that buys or sells a call and a put at different strikes in the same expiration, with the call strike above the put strike; the standard version places both out of the money. Moving the strikes outward makes a long strangle cheaper than a comparable straddle, and its breakevens sit at the call strike plus the total debit and the put strike minus it. A short strangle keeps its full credit if the stock finishes between the strikes.

Buying both options creates a long strangle; selling both creates a short strangle. The two legs share the underlying, expiration, contract deliverable, and quantity.

The long position has a flat maximum-loss region between the strikes at expiration and gains value as stock moves beyond either strike. The short position reverses that shape around its entry credit.

Strangle vs straddle: strikes, cost, and breakevens

Moving a call strike higher and a put strike lower reduces the combined purchase price at the same expiration. Calculate the resulting breakevens from those new strikes and the new total debit.

The example’s 95/105 strangle costs $4.50, compared with $8 for the reference 100 straddle. Their breakevens are $90.50/$109.50 and $92/$108 respectively. This particular strangle creates a wider expiration loss region for a $350 lower entry cost.

Evaluate each candidate directly, including asymmetric strike pairs. Volatility skew and strike selection affect how much each option contributes to the total price.

Strangle Greeks and P&L before expiration

Add both deltas to find the position’s directional exposure. The leg with the larger delta sets the lean, so check both live deltas before you call the position neutral.

Add both vegas and both thetas, then reprice the package across the stock prices and dates in the trade plan. Current P&L equals the combined closing value minus the opening debit for a long strangle.

Map scheduled events to the expiration you choose. Compare the price move and volatility inputs before and after the event to evaluate the complete position at each management date.

How to trade and close a strangle

On the options tape, a call and a put printed together at the same size and expiration, at different strikes, point to one strangle package. Check the strikes and which side bought before you assign the trade a direction.

Open and close the legs together using a net price limit. To close a long strangle, sell both options. To close a short strangle, buy both back. Plan the stock created by exercise or assignment before holding through expiration. The options profit calculator compares the debit, profitable regions, current Greeks, and target-date value with a straddle or iron condor.

Risks and limitations of strangles

• Buy a long strangle for a move past its breakevens. It loses its full $450 debit anywhere from $95 through $105 at expiration and needs a finish beyond $90.50 or $109.50 to profit.
• Weigh the lower cost against the wider loss zone. The example’s breakevens of $90.50 and $109.50 sit outside the $8 straddle’s $92 and $108.
• Reprice both legs for time decay and volatility at each management date. Time decay and falling implied volatility lower both options’ value while the stock sits between the strikes.
• Add long wings to cap a short strangle’s loss. A short strangle has no finite maximum loss on the call side, and its put side loses until the stock reaches zero.
• Holding an in-the-money leg through expiration turns it into a 100-share stock position through exercise or assignment, so close it first unless you want the shares.

Bottom line

The 95/105 strangle costs $4.50 a share against $8.00 for the 100 straddle, and the price of that saving is a wider range to clear, $90.50 to $109.50 instead of $92 to $108. Buy it when you expect a large move in either direction before expiration, and compare the strike gap, debit and breakevens with the straddle before you choose.
