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
