How Volatility Affects Option Prices How Volatility Affects Option Prices Volatility, a measure of how fast and how much prices of the underlying asset move, is key to understanding why option prices fluctuate and act the way they do. In fact, volatility is the most important concept in options trading.

There are two kinds of volatility: implied volatility IV and historical or statistical volatility HV. Whereas HV measures the rate of movement in the price of the underlying asset, IV measures the price movement of the option itself. Another way of looking at it is that IV is the volatility implied by the market price of the option based on an option pricing model.

In other words, it is the volatility that, given a particular pricing model, yields a theoretical value for the option equal to the current price. It usually rises when the markets are in downtrends and falls when the markets are in uptrends.

Historical volatility HV : Also known as statistical volatility SVthis is a measurement of how fast prices of the underlying asset have been changing over time. Because HV is always changing, it has to be calculated on a daily basis. In general, the bigger the HV, the more an option is worth. Volatility can be difficult to grasp unless taken in small bites.
