Everything is on the chart. The trend has been speeding faster than before since the 20/05/14
all these EFs are really scam. If you see VIX and TVIX/UVXY/VXX...These ETFs are suppose to move parallel with either 2X or 3X of VIX based on description. But it never follows. VIX is up a lot but these ETFs never move or move way lesser than VIX. At least SPY is following SnP that good news. Rarely u will see this kind of behavior with SPY. ETFs are literally SCAM.
Try to understand how ETFs are made, first of all it seeks to replicate benchmark based on a single day, and second these ETFs are made with derivatives, and derivatives lose time value fast...those effects are a lot more significant with VIX ETFs...The conclusion is if you want to trade those tickers you dont have to be good but excellent...or just buy the trend! Look at XIV making +50%-60% on a two-three months time frame. I don't call that a scam, maybe you've been on the wrong side of the trade too long
