Iron Condors
What if you could profit from a stock doing absolutely nothing? That is the iron condor. You sell a call spread above the market and a put spread below the market at the same time. If the stock stays between your short strikes, you keep all the premium.
The Structure
An iron condor is two credit spreads combined:
- Bull put spread (below the market) — sell a put, buy a lower put
- Bear call spread (above the market) — sell a call, buy a higher call
All four legs share the same expiration.
Real Example
SPY is at $450. You expect it to stay in a range for the next 30 days.
- Sell the $435 put for $2.80
- Buy the $430 put for $2.00
- Sell the $465 call for $2.50
- Buy the $470 call for $1.70
Total credit: ($2.80 - $2.00) + ($2.50 - $1.70) = $0.80 + $0.80 = $1.60 ($160 per iron condor)
Max profit: $160 — the total credit Max loss: $340 — width of one side ($5) minus total credit ($1.60) Breakeven (lower): $433.40 — short put minus total credit Breakeven (upper): $466.60 — short call plus total credit
SPY can go anywhere between $433 and $467, and you make money. That is a $34 range. The stock can move 3.8% in either direction and you still profit.
Why It Works
The iron condor works because of time decay and probability. You are selling options on both sides that are out-of-the-money. Each day that passes, those options lose time value. If the stock stays in the range, all four options expire worthless and you keep the $160.
You are basically saying: "I bet this stock will NOT make a huge move." In most market conditions, that bet wins more often than it loses.
Ideal Setup
High implied volatility. More premium to collect means a wider profit zone and a bigger credit cushion. An iron condor on SPY when VIX is at 25 is much better than when VIX is at 13.
Range-bound expectation. The stock is not trending hard in either direction. It is consolidating, trading in a channel, or simply quiet.
30 to 45 days to expiration. This is the sweet spot for time decay. Theta accelerates as expiration approaches, but you want to close before the final week when gamma risk spikes.
Liquid underlyings. SPY, QQQ, IWM, AAPL, MSFT — stocks and ETFs with tight bid-ask spreads. You are entering four legs, so transaction costs add up fast on illiquid options.
Strike Selection
The short strikes define your profit zone. Wider short strikes mean higher probability but less credit. Narrower short strikes mean more credit but less room for the stock to move.
Conservative approach: Place short strikes at 1 standard deviation from the current price (roughly 16 delta). This gives about a 68% chance that both sides expire worthless.
Moderate approach: Place short strikes at 20 to 25 delta. More credit, slightly lower probability (around 55% to 60%).
Width of the wings: The long options (protection legs) are typically $5 to $10 away from the short strikes. Wider wings increase max loss but also increase the credit slightly.
Managing the Iron Condor
Take profits at 50%. If you collected $1.60, buy the whole thing back when it is worth $0.80. You made $80 and freed up your capital and risk for the next trade. This is the single most important management rule.
Close the tested side. If SPY rallies to $462 and the call spread is under pressure, consider closing just the call spread side and letting the put spread continue to decay. You take a loss on the call side but the put side is almost worthless, giving you a partial win.
Do not hold to expiration. Close iron condors at 50% profit or with at least 7 to 10 days remaining. The final week is when gamma risk makes the position unpredictable.
Close the whole trade at 2x the credit. If the iron condor moves against you and is now worth $3.20, close it. The loss is $1.60 per spread ($160). That is manageable. Do not wait until it is worth $4.50.
What Can Go Wrong
Big moves. A 5% gap in SPY blows through one side of your condor. This is the main risk. You can mitigate it by not holding through major events (Fed meetings, earnings on component stocks).
Trending markets. If SPY trends steadily higher for three weeks, your call spread is in trouble even without a gap. Iron condors need range-bound conditions.
Adjusting too much. Some traders keep rolling and adjusting a broken condor, adding to the position and increasing risk. Sometimes the best adjustment is closing for a loss and moving on.
The iron condor is a portfolio staple for premium sellers. Master it, and you have a reliable strategy for sideways markets.
