Implied volatility is determined mathematically by using current option prices and the Black-Scholes option pricing model. The resulting number helps traders determine whether the premium of an option is "fair" or not. It is also a measure of investors' predictions about future volatility of the underlying stock. Implied volatility rises when the demand for an option increases and when the market's expectations for the underlying stock is positive. You will see higher-priced option premiums on options with high volatility. On the other hand, implied volatility decreases with a lesser demand and when the underlying stock has a negative outlook. You will see higher-priced option premiums on options with high volatility, and cheaper premiums with low volatility.
It should also be noted that earnings announcements and news releases can have an impact on implied volatility. You may see a rise in implied volatility prior to an announcement, with a sharp drop-off in implied volatility afterwards.

In this case, the table must be horizontally scrolled (left to right) to view all of the information.

- Left-click with your mouse anywhere on the table.
- Use your keyboard's left and right arrows to scroll the table.
- Repeat this anywhere as you move through the table to enable horizontal scrolling.
