Take a look at this chart. The $vxx is constantly getting crushed due to the fact that the front month $vix futures are always in contango. There are many strategies to sell the $vxx short, but look at this chart and you can likely come up with some good ideas.
The move down yesterday in the overall markets provided a good opportunity to take some $xiv or short $vxx $tvix $uvxy exposure. The market overreacted over some taper talk and gave you a spike in the VIX which was making new lows under 12. It closed the day at 13.60 range and today is back flirting with breaking 12 again. This continuously happens in the VIX and we know the best way to play this is through the CONTANGO that is in the VIX etfs! Yesterday I shorted 35% more $tvix to my existing position on that end of the day spike. This morning i took that 35% off for a 6% gain. Be carerful, use stops, do not bet to big or more than you are willing to lose. Shorting these etfs and Being long $ziv and $xiv are by far my most profitable and Predictable gains.
Hope you take advantage of them.
