All qualifying options need valid bid and ask prices to show market views on which strike prices will be met before expiry. While the formula is mathematically complex, it theoretically estimates the S&P 500 Index volatility by averaging the weighted prices of various SPX puts and calls across many strike prices. Henry Shwartz, Vice President, Client Engagement, provides insight into recent options market activity. 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). As the derivatives markets matured, 10 years later, in 2003, the CBOE teamed up with Goldman Sachs and updated the methodology to calculate the VIX differently.

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. 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.
What is volatility?
Traders can use VIX futures, options, and ETFs to hedge or bet on changes in the index’s volatility.In general, volatility can be measured using two different methods. The first method is based on historical volatility, using statistical calculations on previous prices over a specific time period. This process involves computing various statistical numbers, like mean (average), variance, and the standard deviation on the historical price data sets.
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. The Cboe Volatility Index® (VIX® Index) is a leading measure of market expectations of near-term volatility conveyed by S&P 500 Index®(SPX) option prices. Since its introduction in 1993, the VIX® Index has considered by many to be the world’s premier barometer of investor sentiment and market volatility. Such VIX-linked instruments allow pure volatility exposure and have created a new asset class.
- The VIX has paved the way for using volatility as a tradable asset, albeit through derivative products.
- Notably, US inflation expectations have barely budged on this latest jump in oil prices, in sharp contrast to the 2022 Russia/Ukraine invasion.
- Traders making bets through options of such high beta stocks utilize the VIX volatility values in proportion to correctly price their options trades.

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). The VIX attempts to measure the magnitude of the S&P 500’s price movements (i.e., its volatility). The more dramatic the price swings in the index, the higher the level of volatility, and vice versa. Welcome to your go-to place for information about the VIX® complex, including VIX options and futures.
However, the VIX can be traded through futures contracts, exchange-traded funds (ETFs), and exchange-traded notes (ETNs) that own these futures contracts. Options and futures based on VIX products are available for trading on the CBOE and CFE platforms, respectively. The VIX was the first benchmark index introduced by CBOE to measure the market’s expectation of future volatility.
Such volatility, as implied by or inferred from market prices, is called forward-looking implied volatility (IV). A research paper outlining the opportunities created by using market uncertainty. This paper explains how the strategy of selling volatility has generated higher returns with smaller losses, compared with traditional equity portfolios.

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. For instance, a stock with 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 proportion to correctly price their options trades. Following the popularity of the VIX, the CBOE now offers several other variants for measuring broad market volatility.
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. 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 between 23 and 37 days. The second method, which the VIX uses, involves inferring its value as implied by options prices.
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. 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.
The CBOE Volatility Index (VIX) is a real-time market index extensively used by investors to evaluate market sentiment and perceived risk. By representing the expected volatility of the S&P 500 over the next 30 days, the VIX acts as a barometer of investor fear and uncertainty, making it a crucial indicator in assessing market dynamics. VIX measures market expectation of near term volatility conveyed by stock index option prices. This document provides investors with simple guidelines that translate VIX Index levels into potentially more meaningful predictions or measures of market sentiment.
