Turn Volatility to Your Advantage

Welcome to your go-to place for information about the VIX complex – learn to measure, model and trade market moves with the world’s widest array of volatility products and resources.

Volatility measures the frequency and magnitude of price movements, both up and down, that a financial instrument experiences over a certain period of time. The more dramatic the price swings in that instrument, the higher the level of volatility. Volatility can be measured using actual historical price changes (realized volatility) or it can be a measure of expected future volatility that is implied by option prices. The VIX Index is a measure of expected future volatility.

Cboe Global Markets revolutionized investing with the creation of the Cboe Volatility Index® (VIX® Index), the first benchmark index to measure the market’s expectation of future volatility. The VIX Index is based on options of the S&P 500® Index, considered the leading indicator of the broad U.S. stock market. The VIX Index is recognized as the world’s premier gauge of U.S. equity market volatility.

The VIX Index estimates expected volatility by aggregating the weighted prices of S&P 500 Index (SPXSM) puts and calls over a wide range of strike prices. Specifically, the prices used to calculate VIX Index values are midpoints of real-time SPX option bid/ask price quotations.

The VIX Index is used as a barometer for market uncertainty, providing market participants and observers with a measure of constant, 30-day expected volatility of the broad U.S. stock market. The VIX Index is not directly tradable, but the VIX methodology provides a script for replicating volatility exposure with a portfolio of SPX options, a key innovation that led to the creation of tradable VIX futures and options.

On a global basis, it is one of the most recognized measures of volatility -- widely reported by financial media and closely followed by a variety of market participants as a daily market indicator.

Following the successful launch of VIX futures, Cboe Options Exchange introduced VIX options in 2006, providing market participants with another tool to manage volatility. VIX options have monthly and weekly expirations and trade during U.S. regular trading hours and a limited global trading hours session (2:00 a.m. to 8:15 a.m. CT). VIX options enable market participants to hedge portfolio volatility risk distinct from market price risk and trade based on their view of the future direction or movement of volatility.

Introduced in 2004 on Cboe Futures Exchange (CFE), VIX futures provide market participants with the ability to trade a liquid volatility product based on the VIX Index methodology.

Monthly and weekly expirations are available and trade nearly 24 hours a day, five days a week. VIX futures provide market participants with a variety of opportunities to implement their view using volatility trading strategies, including risk management, alpha generation and portfolio diversification.

VIX® Futures & Options Strategies

VIX futures and options have unique characteristics and behave differently than other financial-based commodity or equity products. Understanding these traits and their implications is important. VIX futures and options may provide market participants with flexibility to hedge a portfolio, employ strategies in an effort to generate returns from relative pricing differences, or express a bullish, bearish or neutral outlook for broad market implied volatility.

More VIX Strategies

Portfolio Hedging

One of the biggest risks to an equity portfolio is a broad market decline. The VIX Index has had a historically strong inverse relationship with the S&P 500® Index. Consequently, a long exposure to volatility may offset an adverse impact of falling stock prices. Market participants should consider the time frame and characteristics associated with VIX futures and options to determine the utility of such a hedge.

Long/Short Volatility

VIX futures provide a pure play on the level of expected volatility. Expressing a long or short sentiment may involve buying or selling VIX futures. Alternatively, VIX options may provide similar means to position a portfolio for potential increases or decreases in anticipated volatility.

Risk Premium Yield

Over long periods, index options have tended to price in slightly more uncertainty than the market ultimately realizes. Specifically, the expected volatility implied by SPX option prices tends to trade at a premium relative to subsequent realized volatility in the S&P 500 Index. Market participants have used VIX futures and options to capitalize on this general difference between expected (implied) and realized (actual) volatility, and other types of volatility arbitrage strategies.

Term Structure Trading

One of the unique properties of volatility – and the VIX Index – is that its level is expected to trend toward a long-term average over time, a property commonly known as "mean-reversion." The mean reverting nature of volatility is a key driver of the shape of the VIX futures term structure and the way it can move in response to changes in perceived risk. CFE lists nine standard (monthly) VIX futures contracts, and six weekly expirations in VIX futures. As such, there is a wide variety of potential calendar spreading opportunities depending on expectations for implied volatility.
