VOLATILITY INDEXES

Perhaps the most popular measure of the level of implied volatility in index options is the CBOE Volatility Index^®, known by its ticker symbol VIX^®. VIX, introduced by CBOE in 1993, measures the volatility of the U.S. equity market. It is used by some traders as a general indication of index option implied volatility. Implied volatility levels in index options change frequently and substantially. Consequently, when trading short-term index options, traders should forecast the index level, the time period, and the volatility level. Traders of long-term index options should also include a forecast of interest rates.

Futures on the CBOE Volatility Index (VIX) were introduced in 2004 after the methodology for VIX was changed; please visit www.cboe.com/vix for VIX updates.

The page www.cboe.com/volatility has an overview of several volatility indexes.

Options involve risk and are not suitable for all investors. Prior to buying or selling options, a person must receive a copy of Characteristics and Risks of Standardized Options, which is available from The Options Clearing Corporation, One North Wacker Dr., Suite 500, Chicago, IL 60606, or by calling 1-888-OPTIONS.
