TL;DR. An iron condor is a four-leg options trade that pays you a small credit today in exchange for a small, defined loss if the underlying stock or index makes a big move. You sell one out-of-the-money put spread and one out-of-the-money call spread on the same expiration. You want the stock to sit between the two short strikes at expiration — that’s where you keep everything you collected. It’s the classic strategy for markets you think are going nowhere.
What an iron condor actually is
Two vertical spreads, one expiration, opposite directions. On the put side, you sell a put at a strike below the current price and buy another put at a strike further below — a short put spread. On the call side, you sell a call at a strike above the current price and buy another call at a strike further above — a short call spread. Same expiration date on all four legs.
The Options Industry Council — the education arm of the Options Clearing Corporation — describes the construction as “Long 1 XYZ 70 call, Short 1 XYZ 65 call, Short 1 XYZ 55 put, Long 1 XYZ 50 put” and notes that the trade profits when the stock sits “inside the inner wings at expiration” (OIC — Short Condor). The long options at the far strikes are the “wings” that turn each side into a defined-risk vertical spread instead of a naked short option.
The trade collects a net credit because the short options (closer to the money) are worth more than the long options (further out of the money). That credit is the maximum you can ever make. The distance between the strikes on either side, minus that credit, is the maximum you can ever lose.
The four legs at a glance
The three formulas that define the whole trade
Every iron condor collapses to three arithmetic answers. Memorize these and you can price the trade in your head before you place it.
- Maximum profit = Net premium received. Reached at any expiration price between the short put strike and the short call strike. That’s straight from OIC: “Maximum profit = Net premium received.”
- Maximum loss = (Width of either wing) − Net premium received. Reached if the underlying settles at or beyond the long strikes on either side. Again straight from OIC: “(High call strike − low call strike) OR (High put strike − low put strike) − net premium received.” (OIC)
- Breakevens = Short put strike − net credit (downside); Short call strike + net credit (upside). Between those two prices, the position finishes green.
Notice the asymmetry that makes iron condors so seductive and so dangerous. On a $5-wide wing collecting $1.00 of credit, you risk $4 to make $1 — a 4-to-1 loss-to-gain ratio. You need to win roughly four out of every five trades just to break even. This is why the strategy’s reputation for “printing money” is misleading: the wins are small and the losses are large. The edge, if it exists, comes from being right about direction (nowhere) more often than the market expects.
A worked example with real numbers
XYZ trades at $100. You expect it to stay between roughly $95 and $105 over the next 30 days. You build a $5-wide iron condor using these four strikes and premiums (illustrative):
- Sell 1 XYZ 30-day 105 call for $1.20
- Buy 1 XYZ 30-day 110 call for $0.40
- Sell 1 XYZ 30-day 95 put for $1.30
- Buy 1 XYZ 30-day 90 put for $0.50
Net credit collected = ($1.20 − $0.40) + ($1.30 − $0.50) = $0.80 + $0.80 = $1.60 per share, or $160 per one-lot iron condor. That is the most you can make.
Wing width = $5. Maximum loss = $5 − $1.60 = $3.40 per share, or $340. That is the most you can lose on either side (you can only be assigned on one side, not both, at expiration).
Breakevens:
- Downside = $95 − $1.60 = $93.40
- Upside = $105 + $1.60 = $106.60
So the position is green from $93.40 up to $106.60. That’s a $13.20 window — roughly ±6.6% around the current price. If XYZ moves less than that, you win. If it moves more, you lose. Everything about iron condor risk management is a fight to keep the price inside that window.
Outcome grid at expiration
| XYZ at expiration | Put spread P/L | Call spread P/L | Total P/L per share | Outcome |
|---|---|---|---|---|
| $85 | −$4.20 | +$0.80 | −$3.40 | Max loss (put side) |
| $92 | −$2.20 | +$0.80 | −$1.40 | Below downside breakeven |
| $93.40 | −$0.80 | +$0.80 | $0.00 | Downside breakeven |
| $100 | +$0.80 | +$0.80 | +$1.60 | Max profit (both spreads expire worthless) |
| $106.60 | +$0.80 | −$0.80 | $0.00 | Upside breakeven |
| $108 | +$0.80 | −$2.20 | −$1.40 | Above upside breakeven |
| $115 | +$0.80 | −$4.20 | −$3.40 | Max loss (call side) |
The payoff diagram — the iconic shape
Plot expiration profit on the y-axis against underlying price on the x-axis and the iron condor draws a flat-topped plateau with sharp cliffs on either side. Between the two short strikes you keep the full credit. Between each short and long strike, profit slopes linearly toward the max loss. Beyond the long strikes, the loss is capped.
When it works, when it breaks
Two market conditions favor the trade. First, a stock or index that is chopping in a range with no obvious catalyst. Second, elevated implied volatility that later declines — you sold rich options, and the whole structure loses value as volatility mean-reverts. OIC states the outlook directly: the investor is “hoping for underlying stock to trade in narrow range during the life of the options” and notes that “an increase in implied volatility, all other things equal, would have a negative impact on this strategy” (OIC).
Two things break the trade. A sharp directional move that punches through one of the short strikes turns a small credit into a large realized loss. And a sudden jump in implied volatility — even without a price move — can push the mark-to-market value of the short options up, showing an unrealized loss you may not want to hold through.
Time decay is the tailwind. OIC: “The passage of time, all other things equal, will have a positive effect on this strategy.” That’s theta. As expiration approaches, the extrinsic value in your short options bleeds out faster than the extrinsic value in your longs, and the trade’s value moves toward zero — which is exactly what you want because you already collected the credit up front.
Theta — the accelerating tailwind
A quick note on index vs single-stock iron condors
Retail traders often run iron condors on index products — SPX, XSP, RUT — instead of single stocks. Three reasons stand out. First, indexes have no single-stock earnings blowups that gap the underlying overnight through a short strike. Second, broad-index options like SPX are cash-settled and European style, so there is no early assignment risk — Cboe states SPX options “can only be exercised at expiration, providing certainty and eliminating early assignment risk” (Cboe — SPX Options). Third, SPX “qualifies for potentially favorable 60/40 tax treatment” under Section 1256 of the Internal Revenue Code (Cboe). Those three attributes materially change the risk profile relative to a single-name condor.
SPX options: the numbers that matter for a condor trader
| Attribute | SPX value | Why an iron-condor trader cares |
|---|---|---|
| Contract multiplier | $100 | Each $1 of premium = $100 P/L per contract |
| Settlement | Cash-settled | No shares delivered on assignment; the account is debited or credited in cash |
| Exercise style | European | Short options cannot be assigned before expiration; the trade cannot be forced closed early |
| Tax treatment | Section 1256 (60% LT / 40% ST) | Blended long-/short-term treatment regardless of holding period |
| Recent daily volume (Jul 29, 2026) | ~5.17 million contracts | Deep liquidity in most strikes and expirations |
| Open interest (same date) | ~22.2 million contracts | Robust two-sided markets for four-leg spread execution |
Common mistakes
- Selling wings that are too narrow for the credit. A $1-wide wing that pays $0.20 gives you a 4-to-1 risk-reward ratio — but a $1-wide wing that pays only $0.05 gives you 19-to-1. That is not an edge, that is picking up pennies. Force a discipline like “minimum credit as a percent of wing width” before you enter.
- Ignoring the earnings calendar. On single-stock condors, an earnings release inside the option’s life will typically push the underlying through one of the short strikes. Either close before earnings or don’t open the trade at all.
- Waiting for max profit. The last few pennies of profit take as long to collect as the first dollars. Many traders close at 50% of max profit to free up buying power and reduce gamma risk into expiration.
- Rolling losers indefinitely. “Rolling” a threatened side to the next expiration for another credit sounds like a fix. It is really just refinancing the loss with more time and more risk. Have a stop-loss level based on multiples of the credit received (e.g. close at 2× credit lost).
- Confusing max loss with margin requirement. Your broker may reserve the full wing width in buying power, not just the net risk. A $5-wide condor costs you $500 in buying power per contract even though your max loss is $340.
Related concepts
The iron condor sits inside a wider family of short-premium strategies. A short strangle is what you get if you drop the long options at the wings — higher credit, undefined risk on both sides. An iron butterfly is what you get if you collapse the two short strikes onto the same price — higher credit but smaller profit zone. A vertical credit spread is one side of the condor on its own — simpler, but takes on directional risk.
All four strategies rely on the same underlying idea: sell rich options premium, buy cheap options premium as a hedge, and let time decay do the work. What differs is how much risk you take and how narrow you make the profit zone.
