On January 6th, 2011 I posted a blog about volatility in the US equity markets (click to see that blog post). The short version of that post was that volatility as indicated by the $VIX was cheap on a historical basis. I suggested that readers get long volatility either through $VIX futures or the VXX ETF. I know that the VXX is called a "widow-maker" by many and that deserves a separate conversation (I will summarize briefly at the end of this post).
