The CBOE Volatility Index—also known as the VIX—is a primary gauge of stock 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. 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 (VXX) are two such offerings that track a certain VIX-variant index and take positions in linked futures contracts.
This process involves computing various statistical numbers, like mean (average), variance, and finally, the standard deviation on the historical price data sets. But for those who are more inclined to trade and speculate, ETFs that track the VIX can be a useful tool. When uncertainty and fear hits the market, stocks generally fall, and your portfolio could take a hit. But because of how they’re constructed, even the best volatility ETFs tend to decline in value over time, even if they do spike higher in times of intense volatility. Investors, analysts, and portfolio managers look to the Cboe Volatility Index as a way to measure market stress before they make decisions.

Options and futures based on VIX products are available for trading on CBOE and CFE platforms, respectively. Volatility values, investors’ fears, and VIX values all move up when the market is falling. The reverse is true when the market advances—the index values, fear, and volatility decline. Meanwhile, the IAI, which also has proven to be a leading indicator to the VIX, has shown some divergence.
VIX vs. S&P 500 Price
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. It tends to rise during times of market stress, making it an effective hedging tool for active traders. Though it can’t be stock market quotes silk lined stainless steel flask invested in directly, you can purchase ETFs that track the VIX. When its level gets to 20 or higher, expectations are that volatility will be above normal over the coming weeks. Just keep in mind that with investing, there’s no way to predict future stock market performance or time the market.
Cboe Volatility Index (VIX) or The Fear Index: Explanation and Its Calculation
- The VIX formula is calculated as the square root of the par variance swap rate over those first 30 days, also known as the risk-neutral expectation.
- She has contributed to numerous outlets, including NPR, Marketwatch, U.S. News & World Report and HuffPost.
- Beta represents how much a particular stock price can move with respect to the move in a broader market index.
- VIX values are calculated using the CBOE-traded standard SPX options, which expire on the third Friday of each month, and the weekly SPX options, which expire on all other Fridays.
- For example, the ProShares VIX Short-Term Futures ETF (VIXY) and the iPath Series B S&P 500 VIX Short-Term Futures ETN (VXX) are two such offerings that track a certain VIX-variant index and take positions in linked futures contracts.
When the VIX declines, investors are betting there will be smaller price moves up or down in the S&P 500, which implies calmer markets and less uncertainty. Downside risk can be adequately hedged by buying put options, the price of which depends on market volatility. Astute investors tend to buy options when the VIX is relatively low and put premiums are cheap.
CBOE Volatility Index (VIX): What Does It Measure in Investing?
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. 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. Over long periods, index options have tended to price in slightly more uncertainty than the market ultimately realizes.
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 higher the VIX, the greater the level of fear and uncertainty in the market, with levels above 30 indicating tremendous uncertainty. As a rule of thumb, VIX values greater than 30 are generally linked to large volatility resulting from increased uncertainty, risk, and investors’ fear.

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.
How Does the VIX Measure Market Volatility?
In finance, mean reversion is a key principle that suggests asset prices generally remain close to their long-term averages. If prices gain a great deal very quickly, or fall very far, very rapidly, the principle of mean reversion suggests they should snap back to their long-term average before long. Market professionals rely on a wide variety of data sources and tools to stay on top of the market.
VIX values below 20 generally correspond to stable, stress-free periods in the markets. 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.

Following the popularity of the VIX, the CBOE now offers several other variants for measuring broad market volatility. VIX values are calculated using the CBOE-traded standard SPX options, which expire on the third Friday of each month, and the weekly SPX options, which expire on all other Fridays. Only SPX options are considered whose expiry period lies within more than 23 days and less than 37 days.

During the time period mentioned above, despite some concerns about the market, the overall IAI actually moved lower. The VIX is considered a reflection of investor sentiment, but one must remember that it is supposed to be a leading indicator. In other words, it should not be construed as a sign of an immediate market movement. 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.
