What Are VXX and VIXY?
Both VXX and VIXY are exchange-traded products that track short-term volatility expectations in U.S. equities.They derive their value from the CBOE Volatility Index (VIX) futures market.
- VXX: iPath Series B S&P 500 VIX Short-Term Futures ETN
- VIXY: ProShares VIX Short-Term Futures ETF
Note: These products do not track the spot VIX directly.
Instead, they maintain a rolling portfolio of front-month and second-month VIX futures contracts.
Why They Matter for Traders
Volatility products like VXX and VIXY act as “fear gauges” – they reflect trader sentiment and expectations for market turbulence.- Rise when traders expect more volatility
- Fall when markets settle down
| Market Behavior | What Happens to VXX/VIXY | Interpretation |
|---|---|---|
| S&P 500 falls sharply | VXX/VIXY spike | Fear or uncertainty rising |
| S&P 500 rises steadily | VXX/VIXY decay | Confidence returning |
| Flat equity markets | VXX/VIXY slowly erode | Futures roll cost (contango) |
Why VXX Doesn’t Move Exactly Like the VIX
VXX and VIXY track VIX futures, not the VIX index itself.Performance differences are mostly due to two effects: 1. Futures Curve Slope
- When volatility is low, the VIX futures curve is usually in contango (future prices > spot).
– VXX loses value daily as it sells cheaper front-month futures and buys costlier next-month futures. - When volatility spikes, the curve can flip to backwardation, allowing VXX to rise faster.
- Both products continuously “roll” a portion of holdings from the front to next-month futures each day.
– This creates a performance drag in calm (contango) markets.

Key Risks

- Their gamma sensitivity makes them useful as indicators, but poor buy-and-hold assets.
