AMEX:VXX IPATH S&P 500 VIX SHORT-TERM FUTURES ETN
Thanks for comment. If you are right, then this VXX is a joke...you see, it takes one week/weeks to dive 10~30%, and you are saying it takes a "2008 crash" to go up 12%? Right? Can you explain please. I remember VIX can go from $12 to $50~70 when S&P market dive 30%, and I do realize VXX is not following VIX in a linear way, I did not expect a 2008 crash to set the TP.
