iPath S&P 500 VIX Short-Term Futures ETN (VXX)

[Antisemetic Asshole30]

Once I wrote a blog about VXX and it's correlation to VIX futures and VIX index, there was none. Here is the chart to stamp it, it's pity for VXX buyers that they expect the one thing and get the "cat in the bag" and lose money in the end. There is no way to make money buying VXX because it's not correlated to VIX futures or VIX index, it's derivative instrument that can make you money only on a short term basis but as a long term investment it's a real waste of money.
My final advise to help you make money in a falling market:
SDS, DXD, QID only X2 leveraged ETF's are real thing, all X3 leveraged ETF's are outright theft of your money.

On this chart you can see how VIX expansion has very little correlation to VXX but SDS on other side is somehow correlated.
Resume: SDS is a better volatility play than VXX.
