VIX FUTURES & VOLATILITY PRODUCTS
Plain English
The VIX ('fear index') measures expected stock market volatility. But you can't buy the VIX directly — you can only trade VIX futures or ETPs like UVXY and VXX. This distinction matters enormously: VIX futures behave very differently from the VIX index itself, and most retail traders lose money on VIX products because they don't understand this.
Going deeper
The CBOE Volatility Index (VIX) measures 30-day implied volatility of the S&P 500 from options prices. It spikes during market crashes (VIX reached 80+ in 2008, 65 in March 2020) and decays during calm periods (often 12-15). Key facts: (1) You cannot trade the VIX spot index directly — you trade VIX futures (/VX on CFE). (2) VIX futures are almost always in contango (front-month trades below the back-month) because volatility tends to normalize. This contango structure destroys long VIX ETP values — UVXY has historically lost 80-90%/year in calm markets. (3) VIX futures roll cost is brutal for longs: when March VIX expires, you must buy April at a higher price. (4) Inverse VIX products (SVXY) profit from contango but get catastrophically squeezed when VIX spikes. (5) Professional vol traders use VIX futures to hedge equity portfolios or express volatility views relative to realized volatility. The proper use: short VIX when it's high and declining, hedge with small long VIX positions before major risk events.
Examples
The Contango Decay Trap
VIX at 20. March /VX futures trade at 21. April at 22.5. May at 23.5. When March expires and VIX is still at 20, you 'roll' to April at 22.5 — paying 1.5 extra. Over 12 months, this roll cost compounds to 50-80% losses even if VIX stays flat. This is why long VIX ETPs destroy wealth in calm markets.
VIX Spike Hedge
You hold a $200,000 equity portfolio. Before a major FOMC meeting with high uncertainty, you buy 2 VIX call options or 1 /VX futures contract. If the market sells off and VIX spikes from 15 to 35, your VIX position gains $10,000–$20,000, partially offsetting equity losses. Cost: the roll decay if volatility doesn't spike.
