Iron condor vs credit spread: is the second side worth adding?

An iron condor is two credit spreads on one stock: a put spread below and a call spread above. Many brokers hold margin for only one side, so the credit nearly doubles for the same hold. The cost is a second way to lose, and the extra credit barely dents a full loss.

The short answer

A single Credit spread is a bet on one direction the stock won't go. An Iron condor bets on two: not too far down and not too far up. It's a bull put spread and a bear call spread opened together.

Pick the single spread while you're learning, or whenever you have a view on direction. Pick the condor only when you truly expect a range and you've already handled a tested spread on each side. The condor's extra credit is real, but so is the extra side that can lose.

Side by side

A worked example (hypothetical)

Copperline Rail, a made-up stock, trades at $100. Everything expires in 30 days.

• Credit spread: sell the $90 put, buy the $85 put. Credit $1.25, or $125.
• Iron condor: the same put spread, plus sell the $110 call and buy the $115 call for $1.00. Total credit $2.25, or $225.

The math:

• Put spread: max loss = ($5 × 100) − $125 = $375. Break-even = $90 − $1.25 = $88.75.
• Condor: max loss = ($5 × 100) − $225 = $275, on whichever side is breached. Break-evens = $90 − $2.25 = $87.75 and $110 + $2.25 = $112.25.

Margin: the same hold, a bigger credit

At expiry, Copperline can't be below $85 and above $115. So many brokers hold the width of one side, $500, for the whole condor, the same as for the single spread. After the credit you keep, your buying power drops by $375 for the spread and $275 for the condor.

That's why condors look so good on the screen. The credit went from $125 to $225, up 80%, and the hold didn't grow at all. Check your broker; not every one treats it that way.

The stock runs through one side

Down through the puts. Copperline drops to $80. The single spread loses its full $375. The condor's call side expires worthless and keeps its $100, so the condor loses $275. The extra side helped, by exactly $100. That's all the "extra" credit can ever do: shave the loss by its own size.

Up through the calls. Now a different month. A big contract win sends Copperline to $125. The single put spread holder keeps the full $125; the stock went the way they bet. The condor's call side is blown through: −$500 on the call spread, plus the $225 total credit = −$275.

Same stock, same move. One trader made $125 and the other lost $275. That's a $400 swing, caused by the side that was added "for free."

Why "learn one side first"

A tested condor is harder to manage than a tested spread. When the stock rushes at your call side, the usual fixes, like rolling the put side up to collect more, put your put strikes closer to a stock that might turn back down. Now both sides are in danger at once. Iron condor tested: what to do walks through those choices.

Run single put spreads and single call spreads first. When you've closed a few that went against you, you'll know what each side feels like. Then put them together. Bull put spread vs bear call spread helps you choose the side.

Spreads need a higher options approval level at most brokers, and in Canada not every broker allows them in a TFSA or RRSP.
