VIX futures have become a vital tool for traders and investors looking to hedge against market volatility or speculate on future changes in market sentiment. Calculating these futures involves a complex methodology that hinges on the intricacies of the VIX index itself, which measures the market’s expectation of future volatility. This article will delve into the specifics of how VIX futures are calculated, highlighting key concepts and processes involved.
The Foundation: Understanding the VIX Index
The VIX, often referred to as the “fear gauge,” is an index that measures the market’s expectation of 30-day volatility. It is derived from the prices of S&P 500 index options, specifically the implied volatilities of a wide range of these options. The VIX is calculated using a formula that incorporates the weighted average of the implied volatilities of options across various strike prices and maturities.
Calculating the VIX Index
Option Selection: The VIX calculation involves selecting a set of near-term and next-term put and call options on the S&P 500 index. These options must have more than 23 days and less than 37 days to expiration.
Out-of-the-Money Options: The focus is on out-of-the-money (OTM) options, as they are more sensitive to changes in market volatility. Both put and call options are used to capture a complete picture of market sentiment.
Weighted Average: The implied volatilities of these OTM options are then weighted by the inverse of the square of the strike prices. This helps ensure that the VIX reflects the true market expectation of future volatility.
Risk-Free Rate: The calculation also incorporates the risk-free interest rate to adjust for the time value of money.
Summation: The final step involves summing up the weighted averages and adjusting them for the time to expiration. This provides the expected variance, which is then converted into the VIX index.
VIX Futures: Extending the Volatility Forecast
VIX futures provide a way to trade on the market’s future expectations of volatility. These futures contracts are cash-settled and based on the expected value of the VIX index at their expiration.
Key Components in VIX Futures Calculation
Underlying Index: VIX futures derive their value from the VIX index, but their prices reflect the market’s expectation of what the VIX will be on the contract’s settlement date.
Time to Expiration: The time remaining until the futures contract expires significantly influences its price. Longer-dated futures tend to be less volatile compared to near-term futures due to the extended time horizon.
Market Sentiment: The pricing of VIX futures also incorporates current market sentiment and expectations about future market conditions. This is influenced by economic indicators, geopolitical events, and overall market trends.
Contango and Backwardation: VIX futures often exhibit contango (when futures prices are higher than the spot price) or backwardation (when futures prices are lower than the spot price). These conditions are influenced by the market’s expectation of future volatility changes.
The Settlement Process
Settlement Value: VIX futures are cash-settled based on the Special Opening Quotation (SOQ) of the VIX index. The SOQ is calculated using the opening prices of S&P 500 index options on the settlement day.
Contract Expiration: VIX futures expire on specific dates, usually 30 days before the third Friday of the following calendar month. The final settlement price is determined on the Wednesday 30 days before the S&P 500 options expire.
Settlement Calculation: The final settlement value is a forward-looking measure of expected 30-day volatility, reflecting the market’s view at the time of expiration.

Practical Implications and Strategies
Hedging Strategies
Hedging with VIX Futures: Investors can use VIX futures to hedge against potential increases in market volatility. This is particularly useful during periods of economic uncertainty or market turbulence.
Inverse Relationship: VIX futures often have an inverse relationship with the stock market. When equity markets decline, volatility tends to increase, making VIX futures an effective hedge.
Diversification: Incorporating VIX futures into a diversified portfolio can reduce overall risk and enhance returns during volatile market conditions.
Speculative Strategies
Directional Trades: Traders can speculate on future changes in market volatility by taking long or short positions in VIX futures. A long position profits from an increase in volatility, while a short position benefits from a decrease.
Spread Trades: Spread trading involves simultaneously buying and selling VIX futures with different expiration dates. This strategy aims to profit from changes in the shape of the VIX futures curve, such as shifts between contango and backwardation.
Arbitrage Opportunities: Experienced traders may exploit arbitrage opportunities between VIX futures and related instruments, such as VIX options or volatility ETFs.
Conclusion
The Intricacies of VIX Futures Calculation
Calculating VIX futures involves a comprehensive understanding of the VIX index, market expectations, and the dynamics of futures pricing. By translating the anticipated volatility of the S&P 500 index into a tradable instrument, VIX futures offer valuable opportunities for hedging and speculation. Mastery of these concepts enables investors and traders to navigate market volatility with greater precision and confidence.
In-Depth Knowledge and Strategic Application
Understanding how VIX futures are calculated and how they can be strategically applied is crucial for anyone looking to engage with these financial instruments. Whether used for hedging or speculation, VIX futures provide a powerful tool for managing and profiting from market volatility.
FAQ on VIX Futures
1.What are VIX futures based on?
VIX futures are based on the CBOE Volatility Index (VIX), which is a measure of expected volatility in the market over the next 30 days. The VIX itself is derived from the prices of options on the S&P 500 index.
2.Are VIX futures liquid?
Yes, VIX futures are generally considered liquid instruments. They are actively traded on various futures exchanges and offer sufficient volume for traders and investors to enter and exit positions without significant price impact.
3.Does VIX predict future volatility?
The VIX is often referred to as the “fear gauge” because it reflects market expectations of future volatility. However, it does not predict specific directional movements in the market. Instead, it indicates the magnitude of expected price fluctuations over the next month.
4.What happens when VIX futures expire?
When VIX futures contracts expire, settlement occurs based on the value of the VIX at that time. For cash-settled VIX futures, the settlement price is determined by the opening level of the VIX on the settlement day. Physical delivery is not an option for VIX futures; all contracts are cash-settled.
5.Do VIX futures trade overnight?
VIX futures trading hours typically align with regular trading hours of the underlying equity index futures, such as the S&P 500 futures. While there may be limited electronic trading outside regular hours, liquidity is generally lower during these periods compared to regular trading hours.
