Just to be clear, the point of showing these results is not to imply that readers should choose the best performer in recent history. To the contrary, that would usually be a bad idea.
To illustrate, below in grey are the results of all of the simple strategies we’ve blogged about previously, trading XIV and VXX since 2005 (1). The bold line in red assumes that at the end of each month we selected the best performing strategy of the previous 6-months and traded just that strategy for the next month.

In terms of risk-adjusted performance (Sharpe and UPI), the red line performed worse than nearly all of the individual strategies.
Because of how volatile VIX ETPs like XIV and VXX are, one day’s difference here or there can have an enormous impact on returns in the short-term. That means choosing strategies based on which one has the hot hand at the moment is usually a bad idea.
