Investors should love bubbles.  That is where are lot of big money can be made.  Avoiding their destruction can be challenging of course.  A valuation anchor will help you recognize and avoid them, while a trendfollowing approach may help you ride them and get off before you crash and burn.  We published a paper a few years ago titled:
