IV Crush: Why Options Lose Value After Earnings, and Why I Rarely Trade Them

IV crush is the sharp drop in implied volatility that hits an option the moment an earnings report is released, and it is why you can buy a call, watch the stock move your way, and still lose money. Before the report, the market knows a big move is coming and prices that uncertainty into every option. After the report, the uncertainty is gone, the inflated volatility drains out of the premium, and the option is suddenly worth far less than you paid, whether the stock moved or not.

I traded derivatives professionally for 22 years, including running covered call portfolios that sold options on hundreds of stocks every month. I have been on the wrong side of IV crush, I have watched students get their first expensive lesson from it, and I eventually built my whole approach around avoiding it. This article explains how it works, how to see it coming on the option chain, and what I actually do when earnings show up on the calendar.

What IV Crush Actually Is

An option's price has two big moving parts besides the stock itself: time and implied volatility. Implied volatility is the market's forecast of how much the stock is likely to move before expiration. When traders expect a large move, they bid up options, and that shows up as higher implied volatility and fatter premiums.

Nothing raises expectations like a scheduled earnings report. Everyone knows the date. Everyone knows the stock could gap 5%, 10%, or more the next morning. So in the days leading up to the report, implied volatility on that stock climbs, sometimes to multiples of its normal level, and every call and put gets more expensive to buy.

Then the company reports. Within minutes, the question is answered. There is nothing left to be uncertain about, so the demand for options evaporates and implied volatility collapses back toward normal. That collapse is the "volatility crush", or IV crush. It happens on every earnings report, on both calls and puts, and it happens whether the stock moves or not.

The result is a trade that feels rigged when it happens to you for the first time. You paid a premium that had a big move baked into it. The event came and went. The volatility left the option. Unless the stock moved by more than what was already priced in, you lost money on a trade where your opinion about the company was correct.

Right on Direction, Still Lost Money

Here is the version of this lesson I have watched play out more times than I can count, and lived through myself early in my career.

A trader likes a company going into earnings. They think the quarter will be strong and the stock will pop, so they buy calls a few days before the report. The company beats. The stock does move up. And the calls barely budge, or actually lose value.

What happened is that the market had already been expecting roughly a 12% move, and the trader paid for that expectation in the form of very high implied volatility. The stock moved 10 or 11%. That is a big move by any normal standard, but it was less than what the options had priced, and once the volatility came out of the contract, the price gain on the stock was not enough to cover it. Right on direction. Wrong on pricing. Losing trade.

That is the whole problem with earnings in one sentence: you are not betting on whether the stock goes up. You are betting on whether it goes up by more than everyone already expects. That is a much harder bet, and you are paying a premium for the privilege of making it.

How to See the Expected Move Before You Trade

The good news is that the market shows you its expectation right on the option chain. You do not have to guess.

Find the first expiration that comes after the report date. If the company reports after the close on April 30th, look at the options that expire on or just after May 1st. Then look at the at-the-money strike, the one closest to where the stock is trading. Add the price of the call and the price of the put at that strike. That combined price, the at-the-money straddle, is roughly the move the market is pricing in, up or down.

⚡ Stock trading at $100, reporting tonight.

⚡ The $100 call in the first post-earnings expiration costs $4.00. The $100 put costs $3.50.

⚡ The straddle costs $7.50, so the market expects a move of roughly $7.50, or about 7.5%, in either direction.

Now you know the bar. If you buy that call, the stock has to finish above roughly $104 just to cover what you paid, and if it only rises 4 or 5% on a good report, you are likely giving money back as the volatility drains out. If you sell a put 5% below the market, you are selling inside the range the market itself says is normal for this event. Neither is a mistake by definition, but both are a lot less attractive once you can see the number.

Sellers Do Not Get a Pass

New traders sometimes hear all this and conclude that the answer is to be the seller, since the seller collects the inflated premium and benefits from the crush. That is true as far as it goes. But I stopped selling options through earnings a long time ago, and the reason is that traders consistently underestimate how violent a post-event move can be.

Picture it. You sell a put 7% below the market, which feels like a generous cushion. The report comes out and it is bad, and on top of the miss the company guides lower for next quarter. The stock opens down 15%. You are now 8% below your strike, you own a stock you were not planning to own at that price, and the premium you collected covers a fraction of the damage. Every bit of that pain was avoidable by not having the position on that night.

I spent years running large covered call funds, and we used to sell calls straight through earnings because the premium looked so good. Over time we found it was clearly better to pull back and wait. We gave up a little premium and kept a lot more upside, because the stocks we owned were free to run on the good reports instead of getting called away at a strike we had sold the week before. That change came from live trading and from backtesting, not from theory, and it is why I teach the rule I teach today. The full case for being a seller in normal conditions is in Why Is Selling Options Better than Buying Them?, and the honest risk picture is in Is Selling Put Options Safe? Neither argument depends on selling into binary events.

What I Actually Do When Earnings Are on the Calendar

My approach to earnings is boring on purpose. Checking the calendar is step four of the five checks I run before every trade, and it works like this:

📌 Selling a covered call? I look at whether the company reports before the expiration I am considering. If earnings fall inside that window, I do not sell the call. I wait for the report to pass and sell the next month instead.

📌 Selling a put? Same rule. I sell roughly 30-day options, so the question is simply whether they report in the next 30 days. If they do, I am not selling that put here.

📌 Iron condors and credit spreads? The whole point of an iron condor is that the stock stays inside a range. Earnings exist to break ranges. I do not put them on through a report.

📌 Already in a covered call and it is time to roll? If rolling to the next month would carry me through earnings, I usually do not roll. I buy the call back, take whatever small loss is there, sit out the report, and resume selling the following month.

Notice what this does to the trade that got everyone excited. The stock that is paying an unusually rich premium this month is very often paying it precisely because earnings are two weeks away. The premium is not a gift. It is compensation for a risk the market can see and you may not have noticed. I would much rather collect consistent income on companies I actually want to own than swing for the fences every month on the ones with a report coming.

The One Time Buying Into Earnings Makes Sense

I am not going to pretend earnings can never be traded. They can, as a pure tactical play, and I want to be precise about what that means.

If you genuinely believe a company is going to blow out the quarter in two weeks and you can articulate why, a bought option is the right tool for that view, because your loss is capped at the premium and your upside is not. In that case you would want an option with roughly 30 days to expiration, close enough to the event that a big move accelerates its value, with a realistic target. If the stock is at $10 and you think a great report sends it up 20%, you are looking at $12, so you buy the $10 calls and you size the position so that losing every dollar of it is fine.

That last part is the test. You already know the volatility is high and you already know the market has priced in a move. If you go in with your eyes open, with a real edge rather than an opinion, and the trade loses, that is an acceptable outcome, because you knew exactly what you were up against. What is not acceptable is doing this by accident, or doing it every quarter, or doing it with money you cannot afford to lose. It is a lottery ticket with better math than most. It is not a strategy.

Four Questions Before Any Trade Near an Event

Whenever a setup looks attractive, run it through these four questions before you even think about which strategy to use.

1️⃣ Is there an event coming? Earnings, a Fed decision, a product launch, a court ruling, a big economic release. If yes, pause. Early in your trading, that pause should usually turn into a pass.

2️⃣ What is volatility doing? Is implied volatility elevated versus this stock's normal level? Are the premiums inflated? If so, you are paying more to enter and your risk has changed.

3️⃣ Am I getting paid for risk, or paying too much for uncertainty? This single question filters out most bad trades. Buying options into high volatility is paying for uncertainty. Selling them through a binary event is getting paid, but not nearly enough for the tail.

4️⃣ Does this environment match the strategy, or am I forcing it? Buying calls when volatility is already high, or forcing an income trade because it is the first of the month, is how traders start chasing outcomes instead of managing risk. Sometimes the right answer is to sit out.

Event risk, in the simplest terms, is any scheduled or unexpected news that can move a stock sharply and fast. When it is on the calendar, the normal day-to-day rules change, and they change quickly. The Options Industry Council is a good free resource if you want to go deeper on how volatility feeds into option pricing.

Excitement Is Not Opportunity

Most of the money lost around earnings comes from confusing those two words. Earnings week for a stock you own, a big product announcement everyone is talking about, a name that is suddenly all over the news: these feel like opportunity because they feel like something is about to happen. Something is. That is exactly why the options are expensive.

The edge around earnings, if you ever develop one, comes from familiarity. Traders who watch the same handful of stocks for years learn how each one behaves going into a report, how it trades after a beat versus a miss, and how it reacts when the company pre-announces. That knowledge is real, and it is slow to build. Until you have it, the best trade around earnings is almost always the one you do not take.

Discipline is invisible. Nobody measures it. It pays extremely well.
