What Is Implied Volatility (IV) And Why It Matters In Options Trading?

Implied Volatility (IV) refers to the probability of the fluctuation in the market price of a stock, in short, it is a prediction of how volatile the stock can be at a certain point. The higher the IV, the more volatile in price movement the stock is expected to be.

A stock can have a high IV (which means more volatile) when it is approaching the earnings season as the probability of the share price going up or down is higher than the usual period. Stocks can also have high IV when the market is going through uncertainties, especially when the market is bearish (going down).

Why Does IV Matters In Options Trading?

IV matters because the higher the IV, the higher the premium for a given option contract. A high IV means the seller of the option contract (whether PUT or CALL) will have a higher risk of the contract not going his way and thus he will be compensated with a higher premium because of the higher risk involved.

Thus, if you are a seller of an option contract, you may want to consider selling an option contract when IV is high as you can command a higher premium. On the other hand, if you are a buyer of an option contract, you may want to buy when the IV is low.

A Tale Of 2 Tesla Option Contracts

I bought 2 Tesla LEAPS CALL with the same strike price, expiration date and delta on 31 Aug 21 and 15 Oct 21 respectively.

The share price of Tesla that I bought my LEAPS CALL on 31 Aug 21 was $738.18, while the share price of Tesla that I bought my LEAPS CALL on 15 Oct 21 was $839.70.

For that $100 increase in Tesla share price, by right, the premium should have increased by around $20 as the delta of the first CALL option contract was 0.194. However, I bought the 2nd option contract at almost the same premium price as the earlier one at $37.50.

This is due to the high IV for Tesla stock in August compared to the lower IV for Tesla stock in October. The fall in IV (or IV crush) swings the advantage to the buyer who can purchase at a lower premium for a similar contract with the same strike price, date of expiration and delta.

Sell an option (CALL/ PUT) when IV is high and buy an option (CALL/ PUT) when IV is low.
