Understanding Implied Volatility: A Comprehensive Guide

You might be familiar with historical market volatility, which helps us understand the price fluctuations of a security during a specific time period. However, historical volatility would not always be the right measure when predicting price fluctuations. Herein, Implied Volatility (IV) is useful to understand the future volatility associated with a financial instrument. Let’s explore below what implied volatility is and its benefits in detail.

What is Implied Volatility?

Implied volatility helps investors determine future volatility or price fluctuations for a particular financial instrument or stock. It is determined based on the option price. Options are financial contracts based on underlying assets. An option contract allows the holder the right to buy/sell the underlying asset at a pre-decided price on a future date. Also, the option holder does not have the obligation to buy/sell the underlying asset on a future date, as they can ignore the contract on expiration.

This measure is widely used by options traders in the market. You can thus say that Implied Volatility is an effective tool for deciding the option’s price. When it is high for a financial instrument, the associated option will have a higher premium. A financial instrument will experience more price swings when it is high. Similarly, the market will remain calmer when it is low. Investors also use it to determine the market sentiment. An increase in IV can lead to uncertainty in the market, thus leading to a reduction in trading volume.

Factors Affecting Implied Volatility

Now that you have understood the meaning of implied volatility, let us understand the factors that affect this phenomenon. The supply-demand dynamics have a significant impact on it. Usually, it increases when the demand for a particular financial instrument is high. On the other hand, it will decrease when the supply is high or more than the demand. When it increases, the option price or premium also increases.

The risk associated with options is higher due to increased volatility . Market and geopolitical events like political instability, economic reports, and earnings announcements can also have an impact. Price uncertainty and negative sentiment in the market, additionally, increase volatility as investors look to mitigate risks through options.

Why is Implied Volatility Essential?

Both released and historical volatility are based on actual price fluctuations in the past. They can provide insight into past price fluctuations but cannot predict them. Investors use implied volatility to determine the future price fluctuations for a financial instrument. There is more uncertainty in the market with a rise in volatility. For the same rationale, investors consider derivatives as insurance. The price of options and futures increases as more investors hedge their portfolios against price fluctuations.

When volatility is high, uncertainty and market risk rise. When there are increased chances of price swings, investors find it challenging to take better positions. Usually, investors prefer futures and options to cope with the IV and uncertainty in the market.

Pros and Cons of Implied Volatility

It does not consider fundamentals like the P/E ratio, PEG ratio, and Earnings Per Share . For the same rationale, it is used together with other technical and fundamental analysis tools for informed decision-making.
