IV Crush: Implied Volatility Crush Overview (+ tips on how to avoid them)

The phenomenon of IV crush occurs when the extrinsic value of an options contract falls sharply after the occurrence of important corporate events such as earnings. Unfortunately, many newcomers to option trading are caught off balance by this implied volatility crush. Buyers of stock options before earnings release are the most popular way that newcomers to options trading get to know the Volatility Crush.
They are not only surprised to learn that they did not make any money on their option, although the stock went in their favor, they also lost all of their money!
This blog will explain what IV crush is and how to recognize it before it crushes you and avoid it.

What Is Implied Volatility (IV)?

The implied volatility of a security is a measure for predicting the probability of price movement. IV is very useful for forecasting future market movements, supply and demand, and pricing options contracts.

In addition, multiple variables are taken into account when calculating implied volatility. However, supply and demand, as well as time value, are two of the most important deciding factors.

Implied Volatility & Options Trading

In options trading, contracts are often priced using implied volatility. Options with higher premiums result from high implied volatility, and vice versa.

As you are probably aware, we value an option contract using two components: intrinsic value and extrinsic value. If you’re new to options and this sounds confusing, the extrinsic value of an option reflects the “risk premium.”

Furthermore, as the perceived volatility of a stock’s price rises, so does the demand for option contracts on that security. I know that was a mouthful.

When this situation occurs, the extrinsic value of the options rises. As a result, implied volatility has increased. This scenario is common as a company’s earnings date approaches.

Implied Volatility Crush

Traders use the word “IV crush” in options trading to describe a situation in which Implied Volatility drops rapidly. Typically, this occurs after an occurrence has occurred, such as earnings or an FDA approval date.

When do we usually get an IV Crush?

An IV crush typically occurs when the market transitions from a period or event with unknown information to a period or event with known information.

In layman’s words, IV increases in anticipation of an occurrence and falls afterward. Personally, I believe the best example is an upcoming earnings scenario. In our live trading space, we keep an eye on these kinds of stuff.

IV Crush after company earnings are released

Companies are shrouded in mystery, but we get a peek behind the curtain on earnings day. Every quarter, public corporations report their results, which market participants eagerly await.

As a result, implied volatility in options appears to rise before the “major” announcement and then fall precipitously afterward.

In general, if market participants believe that actual earnings will be better than predicted, they will purchase calls in the hopes of profiting from the announcement.

Alternatively, if they believe that real earnings will be smaller than expected, they will purchase puts. The underlying logic is the same as before: they expect to benefit from the announcement.

In other words, the mixture of call and put buyers raise uncertainty in the expectation of a genuine earnings “surprise”. Finally, earnings day arrives, they announce the earnings, and these trades close.

The cumulative effect of the sale in the options reduces uncertainty, resulting in the IV Crush. The option’s value has dropped dramatically as a result of all of this selling.

How to avoid or stop IV Crush?

How can you put a stop to or avoid an IV crush? When implied volatility is big, you can buy. You can also sell options based on earnings. It is important to note that selling options are extremely risky. However, since 80 percent of options expire worthlessly, the sellers are normally in a good position.

IV Crush Options Example

As an example, consider the stock ABC. ABC is trading at $100 the day before earnings in this case. You can purchase or sell the straddle for $2.00 with one day before expiration. This means that the market anticipates a 2% shift the next day, or earnings day ($2.00/$100 = 2% ).

What if, on the other hand, ABC stock had a straddle price of $20 the day before earnings? That means the market anticipates a 20 percent increase in earnings (($20/$100 = 20 percent ).

Based on the two examples presented above, even inexperienced traders will see a considerable difference in the market’s earnings expectations.

And if you were the trader who spotted the 20% scenario and sold the straddle before earnings, you’re in luck. In this scenario, even though the stock moves less than 20% on earnings day, your place is still a winner.

In the 2% case, on the other hand, the trader may do nothing. You’re probably wondering why that decision was made.

So she went back and looked at markets during past earnings reports and discovered that stock ABC moves by an average of 2%. As a result, she assumes her straddle is equally respected and does nothing.

Good or Bad Earnings

If the earnings report contains good, bad, or even new details, we can re-value the stock at this point. And, unless the organization is planning a big event in the near future (for example, putting itself up for sale), uncertainty decreases. And it is here that the magic takes place. Since humans crave certainty, reducing uncertainty lowers volatility.

You must pay attention to what I am about to say: When stocks fall sharply after earnings, the underlying options suffer an IV crush. This can seem counterintuitive as the stocks inversely link to fear.

Consider the S&P 500. Normally, when the S&P falls, we expect the VIX to rise. However, this is not the case when it comes to profits. Even a poor report provides us with useful information about the company’s activities.

This knowledge, regardless of direction, allows stock to be re-priced. In any case, uncertainty has been reduced, and implied volatility has decreased. And this is particularly true in the expiration month with earnings. On a weekly basis, we look for volatility to trade with our portfolio alerts!


An implied volatility crush ( IV Crush) occurs when the extrinsic value of an options contract falls precipitously as a consequence of a significant event, such as the release of corporate earnings or a regulatory announcement.

It arises as a result of rising uncertainty before a major event, followed by a sharp decrease in uncertainty as the event occurs and the results are digested by the general market. An IV crush option is risky because its existence means that even though the price of a stock moves in a trader’s favor, they may still lose their original investment. However, traders can still avoid an IV crush.

Traders may protect themselves by avoiding options with high implied volatility, options with an occurrence occurring in the expiration month, and options with higher implied volatility than historical norms.

However, by doing so, they run the risk of losing out on potentially profitable short-term trades. As in every trading strategy, use effective risk management techniques and incorporate them into a well-thought-out strategic plan. Earnings volatility is a complex event with many moving parts in general. Fortunately, it provides many opportunities for the benefit of astute traders.

Good luck with your trading!
