Here is a link to an interview today with Nouriel Roubini in which he discusses bubbles:
I would argue against those who believe that bubbles could start to form or that they are just beginning to form. I strongly believe that there are many bubbles in existence right now, and the implications of such are massive.
Over the last few months I have written quite a few posts on bubbles, and those posts can be found on in the “Bubbles” category listed on the right-hand side of the home page.
