RE:no movement Shlinker, a combination of VIX futures flat and contango.
HVU upside will be weak compared to S&P drops until we work out of deep contango to a neutral or backwardated market. Then HVU will respond more forcefully to S&P drops. Also, VIX futures can sometimes tend to REACT to S&P moves instead of moving parallel (IE a delay in VIX response to S&P downside).
In case people missed it, HVU tracks the S&P VIX futures linked below, NOT the CBOE VIX futures most commonly quoted on the internet (MW, Yahoo, Google, etc).
