What is IV Crush you ask? Well, as a stock is getting closer and closer to earnings, the market (the market makers) will start pricing in an “implied” move for the price of the stock as earnings approach.

They’re looking at that earnings date as a catalyst that needs to be priced in when selling options on the market (selling to buyers). This means IV goes up as we get closer to earnings and thus, the price of the option goes up.

It’s a big pump, and after earnings, there is usually a huge drop in IV, and this drops the price of the option. If you know about this ahead of time, you can profit from IV Crush like the pros do.

### Stability: Implied Volatility Formula

The implied volatility formula allows you as a trader to see how stable the market views options contract prices. Higher IV means the stock’s price is less stable.

Less stability means more risk. If you’re buying an option with a high implied volatility, you’re saying that there’s a higher chance the option goes into the money. You’ll make more money.

In the money means your option is worth something. In other words, you can sell it. For example, you bought an XYZ call option at $12 and it’s now trading at $15. You can sell it for a $3 gain.

Although, being in the money doesn’t always mean you’ll profit. For example, your gain was $3 but if you paid $3.50 for the option then you wouldn’t make a profit.

Lower IV means less risk. If you buy at a lower implied volatility you are saying you do not think there’s a big chance the price will move. So you do not mind getting paid less to sell.
