A bubble would require an investment firm to make an intentionally risky investment with the intention of selling off at the IPO prior to the collapse of the company. This is what we saw in 2000 and in the 2009 housing bubble. The current state of affairs has companies being bought in cash by other large companies such as Google, Apple, etc. So the public never gets the chance to purchase overly valued stock. Further, of the companies that did have an IPO (Facebook, Groupon, Google) none of them had outrageously high growth. In fact, most of the companies stock values dropped after an IPO (at least initially). All of those are clear signs we are not in a bubble, as it is financially impossible at this point, regardless of the "nature of bubbles." However, 5 years from now, who knows! The bet was for 2020, not 2016.
