Earnings season is when option prices get expensive. Traders know a big move might be coming, so they pay up for options. Some traders take the other side of that demand by selling an iron condor right before the announcement. In this guide, we will explain how the trade works, how to size it using the expected move, and why the extra premium is not free money.
A Quick Refresher: What Is an Iron Condor?
An iron condor is a four-legged options trade. You sell a call spread above the stock price and sell a put spread below it, all in the same expiration. You collect a credit upfront, and you keep it if the stock stays between your two short strikes.
Because both spreads are defined risk, you know your maximum loss before you enter. That defined risk is exactly why traders like the iron condor for earnings, where a stock can gap violently in either direction overnight.
Why Option Premium Gets Inflated Before Earnings
Option prices are driven by implied volatility, which is the market's estimate of how much a stock might move. Before an earnings report, nobody knows if the company will beat or miss, so uncertainty is high and implied volatility rises. Options in the expiration right after the report can become dramatically more expensive than usual.
That inflated premium is what the earnings iron condor tries to capture. You are selling options when they are at their most expensive, hoping to buy them back (or let them expire) after they deflate.
What Is IV Crush?
The moment the earnings report is released, the big question is answered. The uncertainty disappears, and implied volatility collapses. This is called IV crush.
Because of IV crush, an iron condor sold before earnings can be profitable the very next morning even if the stock moved, as long as the move stayed inside your short strikes. The options lose value from the volatility collapse and from time passing, and both effects work in the seller's favor.
Finding the Expected Move
Before placing the trade, you need to know how far the market thinks the stock might move. The quickest estimate is the price of the at-the-money straddle (one call plus one put at the strike closest to the stock price) in the expiration just after earnings.
If a stock trades at $200 and the at-the-money straddle costs about $12, the market is pricing in an expected move of roughly $12, or about 6%, in either direction. That number becomes your map for placing the wings.
Sizing the Wings Around the Expected Move
The core idea is simple: place your short strikes at or beyond the expected move. If the market prices in a $12 move, selling strikes only $8 away means you are betting against the market's own estimate. Selling strikes $13 to $15 away gives the stock room to make a "normal" earnings move and still leave your condor safe.
Example
Stock XYZ trades at $200 and reports earnings tonight. The at-the-money straddle in this week's expiration costs $12, so the expected move is about ±$12 (roughly $188 to $212).
- Sell the $215 call and buy the $220 call
- Sell the $185 put and buy the $180 put
- Total credit collected: $1.60 ($160 per condor)
- Spread width: $5.00, so maximum loss is $5.00 minus $1.60 = $3.40 ($340 per condor)
If XYZ opens the next morning anywhere between $185 and $215, IV crush deflates all four options and the condor can often be bought back for a fraction of the credit. If XYZ gaps to $175, the put side is fully in the money and you take the maximum loss of $340.
Managing the Trade After the Announcement
Many earnings condor traders do not hold to expiration. The bulk of the profit usually shows up the morning after the report, when IV crush hits. A common approach is to close that morning, capture most of the credit, and move on.
If the stock gaps past one of your short strikes, the loss is already defined. At that point you decide whether to close for the loss or manage the tested side, but there is no adjustment you can make while the market is closed and the gap is happening.
The key risk: Earnings gaps happen overnight, when you cannot adjust or exit. A stock can open far beyond the expected move, taking your condor straight to maximum loss with no chance to react. Because you typically risk more than you collect, one bad gap can erase several winning trades. Never size an earnings condor as if the expected move is a guarantee.
The Math Traders Often Miss
In the example above, you collect $160 to risk $340. That ratio only works if you win clearly more often than you lose. Winning two out of three trades at those numbers is roughly breakeven before commissions.
The expected move is also just an average of the market's guesses. Most reports produce moves smaller than expected, which is why the strategy can work. But occasionally a stock moves two or three times the expected move, and those outliers are exactly what the inflated premium is paying you to absorb.
Key takeaway: An earnings iron condor is a bet on the size of the move, not the direction. You profit from IV crush when the stock stays inside your wings, but the premium is inflated for a reason: big gaps are real. Small position sizes are what keep this strategy survivable.
Common Mistakes to Avoid
- Selling strikes inside the expected move: The extra credit is tempting, but you are fighting the market's own estimate of the move
- Sizing too large: Earnings are binary events; a position you cannot afford to lose at max loss is too big
- Holding for the last few cents: Most of the edge comes from the IV crush; the remaining credit rarely justifies the extra days of risk
- Ignoring the company's history: Some stocks routinely blow through their expected move; check how past reports behaved before selling premium
- Not tracking results: Wins feel frequent with this strategy, so you need real records to know whether the occasional max loss is eating your profits

Summary
Trading iron condors over earnings means selling inflated premium right before an announcement and profiting from IV crush when the stock stays inside your wings. Use the at-the-money straddle to estimate the expected move, place your short strikes at or beyond it, and remember that the defined maximum loss is usually bigger than the credit you collect. Keep positions small, close winners after the crush, and track every trade so the numbers, not the feeling of frequent wins, tell you if the strategy works for you.
