请教各位大神The iPath S&P 500 VIX Short-Term Futures ETN, or VXX, is an unsecured debt security issued by Barclays Bank PLC. Itis designed to track the performance of the S&P 500 VIX Short-Term Futures Total Return Index。
简单来说,VXX在追踪http://us.spindices.com/indices/strategy/sp-500-vix-short-term-index-mcap
可为啥用yahoo VXX的return vs SPVIXSTR return的 SCATTER PLOT 完全对不上呢
详见附件
VXX is ETN issued by BarCap tracking SPVIXSTR index. As a note form product, it's subject to default risk of BarCap. This is one of the reason why ETN could be diff from the underlying index.
Another reason is because SPVIXSTR is calculated from VIX futures and ETN is traded OTC. They are from two seperate markets and the barrier and cost of arbitraging between the two markets also ensures no guarantee of convergence between the two.
Here is a reference on my argument of default risk embeded in VXX and it's impact on VXX option pricing: http://www.sciencedirect.com/science/article/pii/S0377221712004614
