Hedging is a fundamental risk management tool. The most common hedging instruments are futures and options associated with a given underlying asset, when available. For equity exposure, index options are also widely used for hedging.

However, hedging can be done not only through equity index options, but also through volatility derivatives, although the latter are considerably more complex and nuanced. In today’s issue, we discuss the evolving dynamics of VIX futures and volatility ETPs, including lead-lag relationships, price discovery, and how hedging flows can influence volatility markets across different regimes and trading periods.

Lead-Lag Relationship Between the VIX Index and VIX Futures

The volatility index, VIX, is a measure of the stock market’s expectation of volatility over the next 30 days. The VIX index is calculated by taking a weighted average of the prices of put and call options on the S&P 500 index. The VIX is sometimes referred to as the “fear index” because it tends to spike when investors are worried about a sudden drop in the stock market.

VIX futures are derivative contracts that allow investors to bet on the direction of the VIX. They are traded on the Chicago Board Options Exchange (CBOE). VIX futures were first introduced in 2004, and they are now one of the most popular derivatives contracts. VIX futures are traded in monthly contracts, and each contract represents a bet on the direction of the VIX index at the end of the contract month.

Reference [1] examined the lead-lag relationship between the VIX index and VIX futures. It utilized the symmetric thermal optimal path (TOPS) method that can handle non-stationary time series.

Findings

  • The study examines the dynamic lead-lag relationship between the VIX and VIX futures markets using the symmetric thermal optimal path (TOPS) method.

  • The results show that the VIX dominated VIX futures during the early years, particularly before the introduction of VIX options.

  • In most periods, the relationship alternates rather than showing persistent dominance by one market.

  • During the initial phase, VIX futures typically lagged the VIX by less than five days.

  • The weaker role of VIX futures in the early period is attributed to lower trading volume.

  • The importance of VIX futures in price discovery increases over time, especially after the launch of VIX options in 2006 and VIX ETPs in 2009.

  • Since 2006, the lead-lag relationship has alternated, with the VIX sometimes leading futures and futures sometimes leading the VIX.

  • The growth of VIX derivatives markets appears to have increased the informational efficiency of VIX futures.

Briefly, in the early days, the VIX index led its futures. However, the dynamics have changed; VIX futures now sometimes lead the spot market. This could be explained by the launch of VIX options and Exchange-Traded Notes.

Intraday Elasticity Between VIX Futures and Volatility ETPs

Reference [2] analyzes the sensitivity of VIX ETPs to movements in VIX futures. Specifically, the authors investigate the intraday price dynamics of the SPVXSTR, along with three VIX ETNs (VXX, XIV, TVIX) and three ETFs (VIXY, SVXY, UVXY), all linked to that index. Rather than relying on standard OLS regression, the study employs quantile regression, which minimizes a weighted sum of absolute errors and allows for asymmetric penalties on over- and under-predictions.

Findings

  • The study analyzes the elasticity of VIX futures to volatility ETP prices using decile regressions on the S&P 500 VIX Short-Term Total Return Index (SPVXSTR).

  • The results show that elasticity is lower near market close but higher during intraday trading, likely reflecting liquidity differences.

  • Elasticity increases at the extreme ends of the return distribution near the close.

  • VXX exhibits significantly higher elasticity than VIXY, attributed to its dominant and largely unhedged note structure.

  • XIV and SVXY display similar elasticity patterns, while TVIX shows roughly half the elasticity of UVXY due to its lower leverage.

  • The findings suggest that intraday liquidity amplifies the responsiveness of VIX futures to ETP price movements.

  • VIX futures are found to be more sensitive to VXX than to TVIX or XIV during most trading periods.

  • Sensitivity to XIV increases throughout the trading day in higher-return environments, likely reflecting increased hedging demand.

  • The study highlights that VIX futures may overreact to ETP flows during stress periods and volatile market closes.

In short, the results show that VIX futures (SPVXSTR) are generally more sensitive to VXX than to TVIX or XIV, with the exception of the late-afternoon window (3:45–4:15 p.m.). Intraday elasticity is elevated—especially near the close and in the tails—implying that VIX futures can overreact to ETP price changes, which creates potential trading opportunities and important considerations for hedging under stress.

Closing Thoughts

Taken together, these studies highlight the evolving dynamics of volatility markets and the growing importance of VIX derivatives and ETPs in price discovery and market behavior. The evidence suggests that lead-lag relationships between the VIX and VIX futures are time-dependent and increasingly influenced by derivative products and hedging flows.

At the same time, the elasticity of VIX futures to ETP activity varies across volatility regimes and intraday periods, implying that liquidity conditions and dealer positioning can materially affect market dynamics. These findings are particularly relevant for volatility traders, portfolio managers, and risk managers operating in increasingly complex derivatives markets.

Understanding Volatility: A Practical Guide to VIX Futures

In this video, Jose Blasco provides an educational overview of volatility, the VIX index, and VIX futures, with a focus on practical trading applications and risk management. A key distinction made throughout the presentation is between risk and volatility, emphasizing that they are related but fundamentally different concepts. He explains realized volatility as backward-looking market movement, while implied volatility, embedded in option prices and represented by the VIX, reflects the market’s forward-looking expectations of future uncertainty. Using examples from the S&P 500 options market, the presentation illustrates how implied volatility behaves similarly to insurance pricing, rising when market participants anticipate greater future risks.

The second part of the presentation focuses on VIX futures and their unique market structure. Blasco explains that VIX itself is not directly tradable and that exposure must be obtained through VIX futures contracts. An important concept discussed is contango, where longer-dated VIX futures trade at higher prices than shorter-dated contracts due to expectations of greater uncertainty further into the future. He also explains why long-term buy-and-hold strategies in VIX products tend to perform poorly because futures prices gradually converge toward spot VIX over time, creating structural decay.

The webinar concludes with practical discussions on volatility trading, hedging applications, leverage, margin requirements, and the role of VIX futures as a distinct asset class rather than a traditional equity investment.

Volatility Weekly Recap

The figure below shows the term structures for the VIX futures (in colour) and the spot VIX (in grey).

U.S. equities continued to trade near record highs this week despite increased volatility following hotter-than-expected CPI and PPI inflation reports. Rising Treasury yields pressured technology stocks, while optimism surrounding the Trump-Xi summit and strong earnings helped support overall sentiment. By week’s end, uncertainty surrounding geopolitical negotiations weighed on risk assets.

Oil prices remained elevated amid supply concerns and ongoing geopolitical tensions. Gold weakened as higher Treasury yields offset safe-haven demand, while Bitcoin was volatile throughout the week, briefly rebounding on optimism surrounding the proposed CLARITY Act before giving back gains amid renewed market uncertainty.

In the volatility market, both spot VIX and short- to mid-term VIX futures remain in contango, with roll yield staying positive. However, mid-term futures (not shown) increased slightly during the week, allowing VIXM to gain while VXX declined.
