An iron condor is a four-leg options strategy that aims to profit when an underlying asset stays within a defined price range until expiration. A standard iron condor collects a net credit upfront, offers limited profit, and carries a limited but potentially larger loss.
It combines:
- A bull put spread
- A bear call spread
Traders generally use an iron condor when they expect low to moderate price movement and believe the underlying asset will remain between two short strikes.
Iron Condor at a Glance
| Feature | Standard iron condor |
|---|---|
| Market outlook | Neutral or range-bound |
| Trade type | Four-leg, defined-risk credit spread |
| Maximum profit | Net premium received |
| Maximum loss | Spread width minus premium received |
| Best-case outcome | Price finishes between the two short strikes |
| Time decay | Usually helps |
| Rising implied volatility | Usually hurts |
| Main risk | A sharp move beyond either short strike |
How Is an Iron Condor Constructed?
A standard short iron condor uses four options with the same expiration date:
- Buy one lower-strike put
- Sell one higher-strike put
- Sell one lower-strike call
- Buy one higher-strike call
The short put and short call define the inside of the range. The long put and long call sit farther outside that range and limit the trade's risk.
Example Structure
Assume a stock trades at $100:
- Buy the $90 put
- Sell the $95 put
- Sell the $105 call
- Buy the $110 call
This position contains:
- A $90/$95 bull put spread
- A $105/$110 bear call spread
The trade earns its maximum profit if the stock finishes between $95 and $105 at expiration.
How Does an Iron Condor Make Money?
An iron condor earns its maximum profit when all four options expire worthless. That happens when the underlying asset finishes between the short put strike and the short call strike.
The trader keeps the net premium received when opening the position.
Suppose the $90/$95/$105/$110 iron condor receives a credit of $1.50 per share:
- Maximum profit: $1.50 per share
- Maximum profit for one standard 100-share option contract: $150
- Lower breakeven: $95 - $1.50 = $93.50
- Upper breakeven: $105 + $1.50 = $106.50
The position is profitable at expiration if the stock finishes between $93.50 and $106.50, before commissions and fees.
What Is the Maximum Loss on an Iron Condor?
The maximum loss occurs when the underlying asset finishes beyond one of the outer long strikes.
The formula is:
Maximum loss = wider spread width - net premium received
For the example above:
- Put spread width: $95 - $90 = $5
- Net credit: $1.50
- Maximum loss: $5 - $1.50 = $3.50 per share
- Maximum loss for one 100-share contract: $350
The maximum loss occurs if the stock finishes at or below $90 or at or above $110 at expiration. The long options cap the loss, making the iron condor a defined-risk strategy.
Iron Condor Profit and Loss by Expiration Price
Using the example above:
| Stock price at expiration | Result |
|---|---|
| Below $90 | Maximum loss |
| $90 to $93.50 | Loss, but less than the maximum |
| $93.50 to $106.50 | Profit |
| $95 to $105 | Maximum profit |
| $106.50 to $110 | Profit declines toward a loss |
| Above $110 | Maximum loss |
The maximum-profit zone lies between the two short strikes. The breakeven points extend beyond those strikes by the amount of premium collected.
Why Does Time Decay Usually Help?
A standard short iron condor is generally a positive-theta strategy. As expiration approaches, the sold options tend to lose value when the underlying asset remains inside the expected range.
Time decay does not remove the trade's other risks. A sharp price movement can outweigh the benefit of passing time, especially when the underlying asset approaches a short strike. The Options Industry Council identifies time erosion as generally helpful for a short iron condor.
How Does Implied Volatility Affect an Iron Condor?
A standard short iron condor is generally hurt by rising implied volatility and helped by falling implied volatility, with other factors held constant.
Higher implied volatility can raise the market value of the options sold in the position. That can make the iron condor more expensive to close before expiration.
For this reason, some traders consider an iron condor when implied volatility is relatively high but expect the underlying asset to stay within a range. Volatility can rise further, and the asset can still make a large move.
What Is the Difference Between an Iron Condor and a Regular Condor?
An iron condor uses both calls and puts, while a traditional condor generally uses options of the same type.
An iron condor can also be described as:
- A short strangle with protective long options
- A bull put credit spread combined with a bear call credit spread
- A defined-risk range-bound trade
The term iron refers to the combination of put spreads and call spreads in one position.
Iron Condor Versus Iron Butterfly
Both strategies are neutral, defined-risk options trades, but their profit zones differ.
| Feature | Iron condor | Iron butterfly |
|---|---|---|
| Short strikes | Usually separated | Usually at or near the same central strike |
| Profit zone | Wider | Narrower |
| Maximum premium | Usually lower | Usually higher |
| Sensitivity to price movement | Generally less concentrated | More concentrated around the central strike |
| Best suited to | A broader expected trading range | A stronger view that price will finish near one level |
An iron condor provides a wider range for maximum profit. An iron butterfly usually collects more premium but has a narrower profitable zone.
What Are the Main Risks?
An iron condor has defined risk, but that does not make every trade small or safe.
A Sharp Price Move
A strong rally can threaten the short call spread. A sharp decline can threaten the short put spread. Once the underlying price moves beyond a short strike, the position can lose value quickly.
Assignment Risk
The short options in an iron condor can be assigned early when the options are American-style. Early assignment can create a stock position before expiration and may require additional capital or immediate trade management.
Expiration Risk
If the underlying asset finishes close to a short strike at expiration, assignment may be uncertain. The final position may not be known until exercise and assignment information is processed.
Event Risk
Earnings announcements, economic reports, mergers, and other major events can cause the underlying asset to move outside the iron condor's profitable range.
Transaction Costs
An iron condor contains four option legs. Bid-ask spreads, commissions, and closing costs can reduce the net credit, especially when the options are illiquid or the position is adjusted often.
The Options Clearing Corporation states that investors should review the Characteristics and Risks of Standardized Options before trading options.
Is an Iron Condor Bullish or Bearish?
A standard short iron condor is market-neutral, rather than strongly bullish or bearish. The trade benefits when the underlying asset remains within a range.
The position can still have a slight directional bias based on:
- The location of the short strikes
- The distance between the put and call spreads
- The credit received
- The option deltas selected
- Changes in implied volatility and time to expiration
A trader expecting a large move would generally choose a different structure. A trader expecting the price to remain relatively stable may consider a short iron condor after calculating the possible loss and deciding how to manage the position.
What Is a Long Iron Condor?
A long iron condor is the opposite position. It normally involves paying a net debit and aims to profit from a large move outside the central range or from a change in volatility, depending on the structure.
When traders casually refer to an "iron condor," they usually mean the short iron condor. In most educational and trading contexts, that version receives a credit and profits from range-bound price action.
Bottom Line
An iron condor is a four-option, defined-risk strategy that profits when an underlying asset stays within a predetermined range. The trader sells an out-of-the-money put spread and an out-of-the-money call spread, collects a premium, and accepts limited profit in exchange for a potentially larger loss.
Before entering the trade, calculate:
- Net credit received
- The two breakeven prices
- Maximum profit
- Maximum loss
- Distance from the current price to each short strike
- Assignment and expiration risks
