This is a test of another common strategy for trading VIX ETPs like XIV and VXX: comparing the VIX index to the longer-dated VXV index. Traders often use this simple approach to judge whether the VIX futures term-structure is in contango (favoring XIV) or backwardation (favoring VXX).
Strategy results trading XIV (inverse volatility) and VXX (long volatility) are in blue, compared to buying and holding XIV in grey, from mid-2004 to present:
Go long XIV at today’s close if the VIX index will close below the VXV index, or go long VXX if it will close above. Hold until a change in position. Read about test assumptions.

Note the similarity in this strategy’s results to our previous test comparing first and second month futures; poor performance during the 2007/08 bear market, and more importantly, poor performance over the last 1+ year.
Monthly r2 between these two strategies = 75%, meaning these two strategies might not make as good of confirming indicators to each other as say our test comparing the VIX to front month futures, where the strategy produced a much more unique equity curve.
