What Is an Iron Condor?
An iron condor is a four-leg options spread that combines a lower-strike put spread with a higher-strike call spread. The common short iron condor sells an out-of-the-money put and an out-of-the-money call, then buys further out-of-the-money options for protection on both sides.
The strategy seeks to profit if the underlying security stays within a defined range through expiration. It is a limited-profit, limited-risk structure, but limited risk does not mean low risk. The position can lose money quickly if the underlying breaks through either side of the range, volatility rises, or the spread is entered at poor prices.
Key Takeaways
- An iron condor has four option legs: two puts and two calls.
- The common income version is a short iron condor, built from a bull put spread and a bear call spread.
- Maximum profit is usually the net credit received when opening the trade.
- Maximum loss is generally the width of the wider spread minus the net credit, before costs.
- The strategy depends on range, time decay, volatility, and disciplined risk management.
Basic Structure
For a short iron condor, the investor might sell a lower-strike put, buy an even lower-strike put, sell a higher-strike call, and buy an even higher-strike call. The sold options define the inner range. The purchased options define the outer protection.
For example, if a stock trades at $100, a trader might sell the $90 put, buy the $85 put, sell the $110 call, and buy the $115 call. The position is profitable if the stock stays between the short strikes at expiration, assuming the credit collected is not overwhelmed by closing costs or adjustments.
Payoff Mechanics
Component | Role in a short iron condor |
|---|---|
Short put | Collects premium but creates downside obligation |
Long lower-strike put | Caps downside loss |
Short call | Collects premium but creates upside obligation |
Long higher-strike call | Caps upside loss |
Net credit | Usually the maximum profit before costs |
Formula
For a balanced short iron condor with equal-width wings, the common maximum-loss formula is:
Maximum Loss = Spread Width - Net Credit Received
If the put spread and call spread are each $5 wide and the investor receives a $1.50 net credit, the maximum loss is $3.50 per share, or $350 per standard contract set before commissions and fees.
What the Strategy Is Really Betting On
A short iron condor is not simply a bet that the stock will go nowhere. It is a bet that the market's priced range is wider than the realized move, and that time decay will work faster than adverse price movement or volatility expansion. The trader is selling option premium on both sides while buying protection against extreme moves.
That means entry price matters. A wide bid-ask spread can consume much of the credit. Low implied volatility can make the credit too small relative to the risk. Major earnings events, regulatory decisions, product announcements, and macro releases can make a range-bound thesis fragile.
Short Iron Condor Versus Long Iron Condor
The phrase iron condor often refers to the short-credit version, but a long iron condor also exists. A long iron condor generally pays a net debit and seeks a move outside the inner range. The two structures have opposite incentives, so the direction of each option leg must be read carefully.
For clarity, many investors describe the trade as a short iron condor or long iron condor rather than relying on the name alone.
Management and Risk
Iron condors require active monitoring. If the underlying approaches a short strike, the investor may close the threatened side, roll the position, reduce size, or accept the defined loss. Letting all four legs run to expiration can introduce assignment and exercise complications, especially when one short option is near the money.
Defined risk can create false comfort. A strategy that risks $4 to make $1 can have a high win rate and still produce poor results if occasional losses are not controlled. The quality of the setup depends on probability, payoff, liquidity, event risk, and the investor's ability to manage the position without improvising under pressure.
The Bottom Line
An iron condor is a range-based options spread with capped upside and capped downside. It can be useful for expressing a neutral volatility view, but the real skill is not in naming the four legs. It is in pricing the range, sizing the risk, respecting assignment mechanics, and knowing when the market has invalidated the original trade.
