Options Implied Volatility

Knowing what options implied volatility is will assist any options trader in making beneficial financial decisions in the options market. Options implied volatility is an important factor when determining the price of an option. Options implied volatility suggests that when option volatility is high, the premium of that option is fairly expensive as compared to other options and when option volatility is low, premiums are relatively inexpensive. Options implied volatility measures options price changes – both increasing and decreasing.

Options Implied Volatility – Historical Volatility

When determining options implied volatility, financial experts and traders often rely on historical data to analyze and determine the volatility of an option price. Historical volatility is a measure of the volatility of an option for the 20 trading days prior to a contract date. This is a percentage expressed to explain the price changes in options implied volatility.

In contrast to historical volatility, options implied volatility is a measure of the pricing of options premiums. This pricing model uses the popular black options pricing calculations. This calculates the market’s estimate of the value of an underlying option, and thus determines the options implied volatility.

Options Implied Volatility – Calculators

There are numerous calculators available to determine options implied volatility. Some of these calculators are part of financial packages offered online, while some of the more basic options implied volatility calculators are offered for free on several internet sites. Options implied volatility calculators are used to calculate the implied volatility in what’s called an “option chain,” or series of options.

For a fee, some calculator sources use real time data to calculate options implied volatility. Both types of data used in calculating options implied volatility can be downloaded from numerous sources.
