Using VIX Futures for Directional Volatility Exposure

Article Quant Q&A · Author: jessica

Summary

The note asks how to take a directional view on volatility while limiting exposure to the underlying’s direction. It points out that straddles, strangles, and iron condors respond to volatility but also carry exposure to other option risk factors, including delta, gamma, theta, and interest rates. A position that begins near delta-neutral can acquire directional exposure as the underlying moves.

The response identifies volatility-linked futures, such as VIX futures, as a more direct way to express a view on implied volatility without taking the same direct position in stock direction or level. It also mentions their possible use in hedging equity returns and diversifying a portfolio. The note gives no contract mechanics, term-structure considerations, or evidence on performance; “pure” exposure is therefore a simplification, and the instrument’s behavior and risks require further analysis.

Key ideas

  • Option combinations remain exposed to factors beyond implied volatility.
  • Delta-neutral positioning can change as the underlying price moves.
  • VIX futures offer a direct instrument for taking a view on implied volatility.
  • Volatility futures may be used to hedge equity returns or diversify a portfolio.

# Directional View of Volatility












What is an option strategy that someone could employ to simply go long/short volatility?? Assuming I want 0 delta(0 gamma if possible) risk in my option position, how do I take a directional view on volatility? I know that Strangles/Straddles/Iron Condors are all ways to play volatility expansion if it goes beyond the width of your strikes. Not to mention you do maintain a 0 delta position until the price starts trending one way or the other for Strangle/Iron Condors. Are these option positions only way to play pure implied vol?

Iron condors/strangles/straddles (or any other option strategies) are affected by volatility, but are NOT pure volatility plays.

All option strategies are affected by a myriad of factors besides volatility, including but not limited to: directional movement in the underlying (delta), rate in change of delta (gamma), time passing (theta), interest rates changes (rho), etc..

If you want to take a pure directional bet on volatility, you can use volatility-related futures, such as the VIX futures.

CBOE VIX Futures

Futures on VIX provide a pure play on implied volatility independent of the direction and level of stock prices. VIX futures may also provide an effective way to hedge equity returns and to diversify portfolios.
