Iron Condor: Defined-Risk Range Trading With Two Credit Spreads

An iron condor commonly refers to a four-leg, defined-risk options position that combines a put credit spread with a call credit spread using the same expiration.

The familiar short iron condor seeks to keep some or all of the opening credit when the underlying remains between the two short strikes through expiration.

Standard short iron condor structure

A typical short iron condor contains:

• long 1 lower-strike put;
• short 1 higher-strike put;
• short 1 lower-strike call; and
• long 1 higher-strike call.

The short put and short call define the inner range. The long options cap losses outside the outer wings.

Maximum profit is generally the net credit received. Maximum loss is generally the width of the wider vertical spread minus that credit.

Defined risk does not mean low risk

The long wings cap the expiration loss, but the trade can still lose a large share of the capital at risk if the underlying moves beyond either side.

Before expiration, implied volatility can increase the position's mark-to-market loss even when the underlying remains inside the short strikes. Early assignment and expiration uncertainty can also create stock exposure.

Iron condor versus short strangle

A Short Strangle sells an out-of-the-money put and call without protective outer options. Its upside risk is theoretically unlimited.

The short iron condor adds long wings, converting that open-ended risk into a defined maximum loss. The tradeoff is that buying protection reduces the premium collected.

Iron condor versus traditional condor

A traditional Condor Spread can use four calls or four puts. An iron condor uses both puts and calls.

Their expiration payoff objectives can look similar, but the structures and assignment pathways differ.

Long iron condor naming

Reversing every leg creates the opposite exposure, sometimes described as a long iron condor. It generally pays a debit and benefits from a sufficiently large move outside the inner range.

That is why “iron condor” should not be interpreted without checking which legs are long and short.

Investor interpretation

Identify the two short strikes, the wing width on each side, expiration, net credit or debit, breakevens, and assignment exposure. A high stated probability of expiring inside the range is not the same thing as a favorable expected return.
