it's probably a better idea to stick with more conservative investments, like Chris King headsets--though you should be sure to check the Chris King Headset Composite Index (CKHCI) first, because even this is not immune to market fluctuations nor to the variations in the PistaDex. (When large numbers of hipsters sell their Pistas the headset market can also become flooded with their 1-inch Chris King headset "upgrades.")
