When different models are tested on one data sample and repeatedly altered in order to be found significant, the results are likely spurious. This is data-snooping – an ever-growing problem in the finance industry likely due to fierce competition and developments in data processing capacity. In academia, although recognized as a deplorable practice, data-snooping is likewise pervasive perhaps as a result of poor incentive structures at both the university and publisher levels. I manifest the problem of data-snooping through multiple academic and industry examples and then summarize Halbert White and Peter Hansen’s offered solutions, White’s Reality Check and Hansen’s Test for Superior Predictive Ability. I demonstrate the application of their tests by examining several passive investment strategies applicable to recent market moves and report my results.
