This trading session, we are seeing both the index and the ETNs head into negative territory. The VIX is testing its 50-day moving average. In the days ahead it will be interesting to see if it can hold up.

United States Natural Gas Fund (UNG) -2.8%

UNG's recent three-day climb marks the fund's longest string of winning sessions seen all year. Unfortunately for those trying their luck with this battered product, selling pressure has since made a comeback and the fund is revisiting lifetime lows.

The premium-laden iPath Dow Jones UBS Natural Gas Subindex Total Return ETN (GAZ) is also heading lower, albeit to a lesser extent.
