Listener questions and comments
Whaley: I don't think people understand it as well as they should. The VIX doesn't trade. It's just a number produced from these 250 S&P 500 option prices. But what does trade are the VIX futures and the VIX options, which are related to VIX but in a strange way. Where VIX is the volatility over the next 30 days, VIX futures is the expectation of the volatility 30 days from now. Those two series don't behave like one another, in fact quite differently. VXX is incredibly actively traded. Would I have thought it would be this actively traded? No, but it is. I think the VIX futures index is particularly staggering. It probably trades more shares in a day than Microsoft. If you look at the turnover ratio, you'll find that it's a huge number. If people were just buying and holding, that number would be much lower.
