Following the popularity of the VIX, the CBOE now offers several other variants for measuring broad market volatility. Examples include the CBOE Short-Term Volatility Index (VIX9D), which reflects the nine-day expected volatility of the S&P 500 Index; the CBOE S&P Month Volatility Index (VIX3M); and the CBOE S&P Month Volatility Index (VIX6M). Products based on other market indexes include the Nasdaq-100 Volatility Index (VXN); the CBOE DJIA Volatility Index (VXD); and the CBOE Russell 2000 Volatility Index (RVX). As the derivatives markets matured, 10 years later, in 2003, the CBOE teamed up with Goldman Sachs and updated the methodology to calculate VIX differently. It then started using a wider set of options based on the broader S&P 500 Index, an expansion that allows for a more accurate view of investors’ expectations of future market volatility.
Options and futures based on VIX products are available for trading on CBOE and CFE platforms, respectively. You might consider shifting some of your portfolio to assets thought to be less risky, like bonds or money market funds. Alternatively, you could adjust your asset allocation to cash in recent gains and set aside funds during a down market.
The VIX attempts to measure the magnitude of price movements of the S&P 500 (i.e., its volatility). The more dramatic the price swings are in the index, the higher the level of volatility, and vice versa. In addition to being an index to measure volatility, traders can also trade VIX futures, options, and ETFs to hedge or speculate on volatility changes in the index. The CBOE Volatility Index (VIX) is a real-time index that represents the market’s expectations for the relative strength of near-term price changes of the S&P 500 Index (SPX). Because it is derived from the prices of SPX index options with near-term expiration dates, it generates a 30-day forward projection of volatility.
How Can an Investor Trade the VIX?
Instead, investors can take a position in VIX through futures or options contracts, or through VIX-based exchange traded products (ETPs). For example, the ProShares VIX Short-Term Futures ETF (VIXY) and the iPath Series B S&P 500 VIX Short-Term Futures ETN (VXXB) are two such offerings that track a certain VIX-variant index and take positions in linked futures contracts. Active traders who employ their own trading strategies and advanced algorithms use VIX values to price the derivatives, which are based on high beta stocks. Beta represents how much a particular stock price can move with respect to the move in a broader market index. For instance, a stock having a beta of +1.5 indicates that it is theoretically 50% more volatile than the market.
A methodology was adopted that remains in effect and is also used for calculating various other variants of the volatility index. The VIX was the first benchmark index introduced by CCOE to measure the market’s expectation of future volatility. For people watching the VIX index, it’s understood that the S&P 500 stands in for “the stock market” or “the market” as a whole. When the VIX index moves higher, this reflects the fact that professional investors are responding to more price volatility in the S&P 500 in particular and markets more generally.
Prices are weighted to gauge whether investors believe the S&P 500 index will be gaining ground or losing value over the near term. Over long periods, index options have tended to price in slightly more uncertainty https://www.fx770.net/ 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.
How Can I Use the VIX Level to Hedge Downside Risk?
On the other hand, during times when the VIX is falling, indicating the possibility of more stability to come in the stock market, it might make more sense to focus on individual stocks or other riskier assets that might fare well during times of growth. Before investing in any VIX exchange-traded products, you should understand some of the issues that can come with them. Certain VIX-based ETNs and ETFs have less liquidity than you’d expect from more familiar exchange traded securities. ETNs in particular can be less liquid and more difficult to trade as well as may carry higher fees.

- As a rule of thumb, VIX values greater than 30 are generally linked to large volatility resulting from increased uncertainty, risk, and investors’ fear.
- The first method is based on historical volatility, using statistical calculations on previous prices over a specific time period.
- Prices are weighted to gauge whether investors believe the S&P 500 index will be gaining ground or losing value over the near term.
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. The VIX, formally known as the Chicago Board Options Exchange (CBOE) Volatility Index, measures how much volatility professional investors think the S&P 500 index will experience over the next 30 days. Market professionals refer to this as “implied volatility”—implied because the VIX tracks the options market, where traders make bets about the future performance of different securities and market indices, such as the S&P 500.

Volatility, or how fast prices change, is often seen as a way to gauge market sentiment, and in particular the degree of fear among market participants. The VIX index tracks the tendency of the S&P 500 to move away from and then revert to the mean. When the stock markets appear relatively calm but the VIX index spikes higher, professionals are betting that prices on the S&P 500—and thereby the stock market as a whole—may be moving higher or lower in the near term.

When the VIX moves lower, investors may view this as a sign the index is reverting to the mean, with the period of greater volatility soon to end. Alternatively, VIX options may provide similar means to position a portfolio for potential increases or decreases in anticipated volatility. Downside risk can be adequately hedged by buying put options, the price of which depend on market volatility. Astute investors tend to buy options when the VIX is relatively low and put premiums are cheap. Such protective puts will generally get expensive when the market is sliding; therefore, like insurance, it’s best to buy them when the need for such protection is not obvious (i.e., when investors perceive the risk of market downside to be low).

The index is more commonly known by its ticker symbol and is often referred to simply as “the VIX.” It was created by the CBOE Options Exchange and is maintained by CBOE Global Markets. It is an important index in the world of trading and investment because it provides a quantifiable measure of market risk and investors’ sentiments. During its origin in 1993, VIX was calculated as a weighted measure of the implied volatility of eight S&P 100 at-the-money put and call options, when the derivatives market had limited activity and was in its growing stages. The second method, which the VIX uses, involves inferring its value as implied by options prices. Options are derivative instruments whose price depends upon the probability of a particular stock’s current price moving enough to reach a particular level (called the strike price or exercise price).
This process involves computing various statistical numbers, like mean (average), variance, and finally, the standard deviation on the historical price data sets. Perhaps the most straightforward way to invest in the VIX is with exchange-traded funds (ETFs) and exchange-traded notes (ETNs) based on VIX futures. As exchange-traded products, you can buy and sell these securities like stocks, greatly simplifying your VIX investing strategy. It’s important to note here that while volatility can have negative connotations, like greater risk, more stress, deeper uncertainty or bigger market declines, volatility itself is a neutral term.
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. Volatility is one of the primary factors that affect stock and index options’ prices and premiums. As the VIX is the most widely watched measure of broad market volatility, it has a substantial impact on option prices or premiums. A higher VIX means higher prices for options (i.e., more expensive option premiums) while a lower VIX means lower option prices or cheaper premiums.
CBOE Volatility Index (VIX): What Does It Measure in Investing?
Large institutional investors hedge their portfolios using S&P 500 options to position themselves as winners whether the market goes up or down, and the VIX index follows these trades to gauge market volatility. The VIX volatility index offers insight into how financial professionals are feeling about near-term market conditions. Understanding how the VIX works and what it’s saying can help short-term traders tweak their portfolios and get a feel for where the market is headed. Since the possibility of such price moves happening within the given time frame is represented by the volatility factor, various option pricing methods (like the Black-Scholes model) include volatility as an integral input parameter. Since option prices are available in the open market, they can be used to derive the volatility of the underlying security. Such volatility, as implied by or inferred from market prices, is called forward-looking implied volatility (IV).
