IV Crush: How to Trade Options Around Earnings

By Bruno Nalon · October 24, 2026 · 5 min read

You buy a call the day before earnings, the company beats, the stock goes up - and your call is worth less than you paid. That is IV crush: the sudden drop in implied volatility after an event the market was waiting for. Once you understand where the extra premium comes from and when it disappears, you can decide whether to sell it, avoid it, or pay for it on purpose.

What IV crush is

Implied volatility (IV) is the amount of movement the options market is pricing in. When a big unknown is coming - an earnings report, a court ruling, a drug approval - traders pay more for options, so IV rises. When the news is out, the unknown is gone, and IV falls back toward normal, often in a single session.

That drop is IV crush. It hits every option on the stock, calls and puts alike, and it hits the options expiring right after the event hardest. An option is made of intrinsic value plus extrinsic (time and volatility) value; IV crush removes a large part of the extrinsic value overnight.

Why options get expensive before earnings

A stock that normally moves 1% a day might move 8% the morning after earnings. Option sellers know this, so they demand more premium to carry that risk, and buyers who want a lottery ticket on the report are willing to pay it. IV usually climbs during the days before the report and peaks the last session before it.

You can see it in the option chain: the expiration right after earnings shows a much higher IV than the expiration a month later. That gap between short-term and longer-term IV is the clearest sign that an event is priced in, and it is roughly how much IV can fall once the event passes.

How to read the expected move

The quickest estimate of how far the market expects a stock to move on earnings is the price of the at-the-money straddle (one call plus one put at the strike closest to the stock price) in the first expiration after the report.

How to read the expected move
Stock price	ATM straddle	Expected move	Range priced in
$50	$3.00	±$3.00 (6%)	$47 to $53
$150	$9.00	±$9.00 (6%)	$141 to $159
$400	$16.00	±$16.00 (4%)	$384 to $416

Compare that number with how much the stock actually moved after its last several reports. If the stock usually moves less than the straddle implies, options look expensive; if it often moves more, they look cheap. Neither is a guarantee - one surprise quarter can move a stock two or three times its usual amount.

Example: right direction, still a loss

Here is how a correct directional call can still lose money. The stock is at $150 the afternoon before earnings. The weekly 150 call, with 5 days to expiration, costs $5.60 with IV at 80%. The 150 put costs about the same, so the straddle is about $11.15 and the market is pricing in a move of about ±$11. The company beats, the stock opens 2% higher at $153, and IV drops to 35%.

Example: right direction, still a loss
	Before earnings	Next morning
Stock price	$150	$153
Days to expiration	5	4
Implied volatility	80%	35%
150 call value	$5.60	about $4.04
Intrinsic value	$0	$3.00
Extrinsic (time and volatility) value	$5.60	about $1.04
Result per contract if sold	-	about -$156

The stock moved in the right direction, but only $3 - far less than the $11 the options were pricing in. The call gained $3.00 of intrinsic value and lost about $4.56 of extrinsic value. Held to expiration with the stock still at $153, the call is worth only its $3.00 of intrinsic value and the loss grows to $260. To break even at expiration, the stock needed to close above $155.60: the $150 strike plus the $5.60 paid.

Four ways to trade around earnings

There is no single right answer. Each approach takes a different side of the volatility premium:

Four ways to trade around earnings
Approach	What you are betting on	Effect of IV crush	Max loss	Beginner fit
Sell an iron condor into earnings	The move stays inside the expected range	Helps you	Defined (width minus credit)	Only with small size
Buy a straddle or strangle	The move is bigger than the expected range	Hurts you	The premium paid	Rarely
Calendar spread	IV of the front expiration falls more than the back	Helps you	The debit paid	Intermediate
Stay out until after the report	Nothing - you skip the event	None	None	Best default

Selling premium into earnings wins often because options are frequently priced for a bit more movement than actually happens, but when it loses, it loses big: a gap through your strikes turns the whole trade into a max loss overnight. If you sell, use defined risk, size it so the max loss is small for your account, and never use a naked short option on an earnings play.

A pre-earnings checklist

Before you open or hold any option over an earnings report, check these five things:

1. The exact date and time. Before the open or after the close changes which session absorbs the move.

2. The expected move from the straddle, compared with the stock's actual moves over the last four to eight reports.

3. The IV gap between the expiration right after earnings and the next monthly expiration - that is roughly how much IV can drop.

4. Liquidity. Bid-ask spreads widen before earnings; wide spreads eat the edge you were trying to capture.

5. The worst case. If the stock gaps twice the expected move against you, can you afford the loss without changing your plans?

How EasyTrade handles earnings

EasyTrade signals are built for steady, multi-week income trades, not earnings bets. When a stock has an earnings report scheduled before the signal's expiration, that stock is skipped. You get fewer signals around earnings season, but the ones you get are not exposed to an earnings gap.

If you already hold a position and an earnings date moves into its window, the usual choice is to close or roll it before the report rather than hope the stock lands inside the expected move.

Frequently asked questions

Does IV crush affect puts as well as calls?

Yes. Implied volatility applies to the whole option chain, so calls and puts both lose extrinsic value when IV drops. Buying puts before earnings has the same problem as buying calls: the stock must move further than the expected move for the trade to pay off.

When exactly does IV crush happen?

In the first trading session after the report. For a company reporting after the close, IV collapses at the next morning's open; for one reporting before the open, it collapses that same morning. Most of the drop happens in the first minutes of trading.

Can you profit from IV crush?

Option sellers can, because they collect the inflated premium and buy it back cheaper after the drop. The risk is a move larger than expected, which can wipe out many winning trades at once. Defined-risk trades such as iron condors cap that loss; naked short options do not.

Is IV crush only about earnings?

No. Any scheduled event with an uncertain outcome can do it: drug trial results, court decisions, product launches, central bank meetings and inflation reports for index options. The pattern is the same - IV rises into the event and falls once the result is known.

How do I estimate how much IV will drop?

Compare the IV of the expiration right after earnings with the IV of the next monthly expiration. After the report, the short-term IV tends to fall toward the longer-term level. If the front month shows 80% and the next month 40%, a drop to somewhere around 40% is a reasonable expectation.
