The VIX is considered a reflection of investor sentiment and has in the past been a leading indicator of a dip in the S&P 500, but that relationship may have changed in recent times. For instance, in the three months between Aug. 8, 2017, and Nov. 8, 2017, the VIX was up 19%—seemingly suggesting anxiety among market participants and implying that the S&P 500 should be on a downward trajectory.

Instead, the VIX looks at expectations of future volatility, also known as implied volatility. Times of greater uncertainty (more expected future volatility) result in higher VIX values, while less anxious times correspond with lower values. 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. 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).

Beta represents how much a particular stock price can move with respect to the move in a broader market index. 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. All such qualifying options should have valid nonzero bid and ask prices that represent the market perception of which options’ strike prices will be hit by the underlying stocks during the remaining time to what is a binary option expiry. Sentiment plays a big role in decision making for the stock markets, and to that extent, it could be a good idea to glance at the VIX. However, the index is far from perfect, and investors should consider how much weight they want to peg on it. However, the VIX can be traded through futures contracts, exchange-traded funds (ETFs), and exchange-traded notes (ETNs) that own these futures contracts.

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. A methodology was adopted that remains in effect and is also used for calculating various other variants of the volatility index. Alternatively, VIX options may provide similar means to position a portfolio for potential increases or decreases in anticipated volatility. The VIX index tracks the tendency of the S&P 500 to move away from and then revert to the mean.

What is the Cboe Volatility Index (VIX)?

Since option prices are available what is business analytics 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). The first method is based on historical volatility, using statistical calculations on previous prices over a specific time period.

  1. However, the VIX can be traded through futures contracts, exchange-traded funds (ETFs), and exchange-traded notes (ETNs) that own these futures contracts.
  2. On the other hand, abnormally high volatility is often seen as anything that is above 20.
  3. Certain VIX-based ETNs and ETFs have less liquidity than you’d expect from more familiar exchange traded securities.

For instance, a stock having a beta of +1.5 indicates that it is theoretically 50% more volatile than the market. Traders making bets through options of such high beta stocks utilize the VIX volatility values in appropriate proportion to correctly price their options trades. 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. Any estimates based on past performance do not a guarantee future performance, and prior to making any investment you should discuss your specific investment needs or seek advice from a qualified professional. VIX values are quoted in percentage points and are supposed to predict the stock price movement in the S&P 500 over the following 30 days.

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. The VIX, which was first introduced in 1993, is sometimes called the “fear index” because it can be used by traders and investors to gauge market sentiment and see how fearful, or uncertain, the market is. That much is understood by most investors, but what exactly is volatility and how is it measured for the overall stock market? You may have seen references to something called the VIX, an index that measures volatility, during times of extreme financial stress.

When you see the VIX above 30, that’s sometimes viewed as an indication that markets are very unsettled. 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).

Prices are weighted to gauge whether investors believe the S&P 500 index will be gaining ground or losing value over the near term. The CBOE Volatility Index (VIX) quantifies market expectations of volatility, providing investors and traders with insight into market sentiment. It helps market participants gauge potential risks and make informed trading decisions, such as whether to hedge or make directional trades. While the VIX itself is an index and cannot be traded, there are funds and notes investors and traders can participate in to gain exposure to the index.

CBOE Volatility Index (VIX): What Does It Measure in Investing?

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. This formula was developed by Vanderbilt University Professor Robert Whaley in 1993. As an investor, if you see the VIX rising it could be a sign of volatility ahead. You might consider shifting some of your portfolio to assets thought to be less risky, like bonds or money market funds.

When VIX returns are higher, market participants are more likely to pursue investment strategies with lower risk. 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. 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.

The CBOE Volatility Index (VIX) is a measure of expected price fluctuations in the S&P 500 Index options over the next 30 days. The VIX, often referred to as the “fear index,” is calculated in real time by the Chicago Board Options Exchange (CBOE). 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. Greater volatility means that an index march 2021 fed meeting preview or security is seeing bigger price changes—higher or lower—over shorter periods of time. The VIX has paved the way for using volatility as a tradable asset, albeit through derivative products. CBOE launched the first VIX-based exchange-traded futures contract in March 2004, followed by the launch of VIX options in February 2006.

In August 2024, the VIX jumped above 60, a level not seen since the market meltdown in the initial stages of COVID-19 in March 2020, as worries grow about a possible recession. 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. Volatility is one of the primary factors that affect stock and index options’ prices and premiums.

The VIX is merely a suggestion, and it’s been proven to be wrong about the future direction of markets nearly as often as it’s been right. That’s why most everyday investors are best served by regularly investing in diversified, low-cost index funds and letting dollar-cost averaging smooth out any pricing swings over the long term. One of the most popular and accessible of these is the ProShares VIX Short-Term Futures ETF (VIXY), which is based on VIX futures contracts with a 30-day maturity. Some exchange-traded securities let you speculate on implied volatility up to six months in the future, such as the iPath S&P 500 VIX Mid-Term Futures ETN (VXZ), which invests in VIX futures with four- to seven-month maturities.

The VIX was the first benchmark index introduced by CCOE to measure the market’s expectation of future volatility. 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. 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).
