The IPath VXX Volatility ETN Rockets Towards Biggest One-day Gain In Its History

The Barclays iPath S&P 500 VIX Short-Term Futures ETN , a vehicle used to bet on stock market volatility, rocketed 24% in premarket trade in the aftermath of the Brexit vote. That puts the VXX on track to post the biggest one-day percentage gain since it began trading on Jan. 30, 2009. About 2 1/2 hours ahead of the open, volume spiked to about 3.7 million shares, making it the most-actively traded in the premarket. The VXX was changing hands at $16.91, which would be the highest closing level since April 15.
